We've had several major releases in Q3, including the official Spacemesh Wallet and go-spacemesh 1.7.

Learn about these developments and more in our quarterly update.

Research & Development


The Spacemesh Wallet

Our dev team has created a light, easy-to-use wallet where you can store your SMH coins without having to run a full node. Since its release in August, we’ve made several small improvements and adjustments.

This release is the first step of an ongoing effort to make smeshing easier and more accessible. See Node Split below for more details.


Go-Spacemesh 1.7

The 1.7 series has been released, as part of our preparations for the ATX merge. If you’re upgrading from a release in the 1.6 series, please note the extensive migration process required for this series to operate and the temporary doubling of disk space usage.


Node Split/Smeshing Service

In our ongoing effort to lower the barrier for smeshing, we’re exploring a new direction for reducing the system requirements for smeshers. The idea is to re-architect the internal modules in go-spacemesh, isolating the smeshing logic from the passive consensus code. By dividing the node along those lines, we can enable users to run the lightweight, yet sensitive (access to private key) smeshing logic separately from the rest of the node. This can enable users with limited resources to use a remote node for their smeshing.

We want to introduce a node-split where we split node into multiple smaller entities as shown in the picture:

We believe that such a design will also be useful for larger smeshers, as it enables them to run small, lightweight smeshing services next to their PoST data. All the smeshing services that they run can then connect to a single passive node serving their entire operation.


ATX Merge

In September, we launched a dedicated testnet for preliminary testing of this feature, which we have continued to oversee and manage, paying close attention to the merged ATXs. At the same time, APIs have been finalized, and we’re finalizing the implementation of malfeasance proofs.


Sync v2

We’re close to shipping the initial version of Sync v2, which will allow syncing in a manner similar to the torrent protocol (parts of data from different peers). We will soon enable it on ATXs.


Explorer and Dashboard v2

Both our Explorer and Dashboard are now V2. Please note that the old versions with all their APIs are deprecated.


Node Performance Optimization

We have identified several areas for optimization and are working on them. This includes disk usage optimizations, memory consumption optimizations, and CPU usage optimizations. Many of these improvements will be included in upcoming 1.7 releases.

Hare4, which optimizes bandwidth usage, has also been fully developed and we’re preparing to enable it on mainnet soon.


Network Decentralization

Routing discovery is enabled for all Smapp users currently, which means that more peers behind NAT will become accessible.


Research


Athena VM

Everything we need to launch the initial, proof of concept Athena testnet is now in place on the Athena side. We merged a major update that includes the remainder of the initial set of host functions, a SDK and procedural macros used for writing Athena programs, and some other nice features such as the ability for a program to have multiple entry points.

The other big piece of news is that two additional developers have joined the Athena project. It took a few weeks but they’re now up to speed and have begun to make major contributions to Athena.

We also have a final proof of concept Spacemesh wallet template implemented in Athena Rust. For now it implements only two of the proposed four wallet methods, spawn and send, but this is sufficient for the initial testnet.

If work on the Athena Rust code appears to have slowed, it’s only because we now have everything we need for the testnet, and we’re totally focused on finishing the initial integration with go-spacemesh in order to launch the testnet.

The latest update is here, with more details.


PoST Merge

Spacemesh is suffering from “smesher identity overload” where millions of ATXs are published every epoch, placing a significant burden on everyone running a Spacemesh node. This is not because millions of individuals are smeshing, but rather because the existing PoST algorithm allows a form of resource optimization available only to individuals who split their storage allocation between many small identities.

To address this issue, we’ve developed a modified version of the PoST protocol that eliminates the indirect incentive to split large identities into smaller ones. A side effect of this change is that smesher weight will no longer be constant across epochs, but will instead slightly fluctuate.

To actually reduce the number of existing identities, and not just discourage new smeshers from splitting, we needed to allow large smeshers–whose identities are already fragmented into many small ones–to merge them without the need to re-initialize. Merging identities will be enabled even before the new PoST, but that only means putting multiple PoST proofs in the same ATX. Once the PoST v2 is rolled out, merged identities will only need to include a single consolidated PoST proof. A consolidated proof from multiple identities will take up slightly more space, but the size increase will be sublinear and capped (after a certain number of included identities, proofs will not grow anymore).

Another problem large identities face today is the huge upfront k2pow requirement. Today, k2pow grows linearly with the allocated space, because the benefit of “cheating” (replacing allocated space with trying a huge number of nonces to achieve a similar weight) increases linearly, as well. To allow sublinear k2pow increases, we require larger identities to provide slightly larger proofs. The larger the proof, the smaller the benefit of each additional nonce, so the cost to create another nonce (k2pow) can be smaller with no loss of security. This has an added benefit of nudging large smeshers to merge their identities, in order to do less total k2pow.

Q2 of 2024 has been a crazy time for Team Spacemesh. In this update, we’re excited to give you all a look at all the highlights.

Research & Development


ATX Merge

The merging of Activation Transactions (ATXs), which we aim to release with version 1.7, serves multiple critical functions aimed at enhancing network efficiency and security. We landed on ATX merge as a solution to address the network growth and the unexpectedly high number of smeshing identities, which has been taxing the network due to individual optimizations by large smeshers. The ATX merge is designed to reduce network congestion and enhance overall performance and scalability.

You can read the full overview here.


ATX Merge Specification

Version 1 (V1)of ATX merge incorporates the following features:

  • The inclusion of a certificate within the ATX that covers multiple PoSTs.

  • Any ATX containing multiple PoSTs is required to also include a 32-byte ID.

  • This 32-byte ID serves as a reference to another ATX that contains the actual marriage certificate.

  • There is a limitation of one marriage per set.

Version 2 (V2) is planned to expand upon these capabilities by introducing additional features such as:

  • Allowing more than one marriage per set.

  • Subset merges.

  • Merge announcements.

Implementation work can be viewed here.


Athena VM

The Athena project has completed its initial research and low-level design phases, resulting in a working VM compatible with the RV32IM instruction set. It is now entering the integration phase to add blockchain functionalities and interface with go-spacemesh. Athena uses the SP1 RISC-V VM as its core VM, but without the ZK components (SP1 is a RISC-V-based zkVM).

The implementation is here and you can even try it out yourself!

An in-depth update for the month of June is available on the official Athena website, along with a live demo on the Spacemesh Youtube channel.


Light Wallet

We understand that not everybody who holds Spacemesh coins wants to smesh. To address the need for a less resource-intensive solution for those who only want access to their wallets, we are in the process of developing our light wallet, Spacemesh Wallet.

It may be coming very soon indeed… 👀👀


Halborn Audit

We partnered with Halborn for a security audit of the Spacemesh protocol. Halborn is a leading blockchain security firm, focusing on auditing blockchain protocols and smart contracts to make them more secure. Given the adversarial and open environment of Web3, having our codebase audited was a fundamental step towards making Spacemesh more secure, robust, and resilient against any potential attacks. The audit is now complete and the full audit repor is available here.


Hardware Wallet Support

We truly believe in the ability to have self-custody of one’s own coins. As such, to further facilitate this goal, we are in the process of making Spacemesh compatible with Ledger hardware wallets.


API v2

A set of new and improved APIs has been in development and we will shortly begin testing nodes which will expose these APIs by default.


Public API Availability

mainnet-api is available, as well as testnet-13-api. The swagger docs are accessible via the `/docs` endpoint.


Testnet

Using the Testnet is a great way to experiment with the protocol without any real funds at risk. About two months ago, we launched Testnet-12 with a 1-day epoch. This network ran for several weeks before experiencing problems with the Beacon protocol. We launched its replacement, Testnet-13, last week.


1:N

This is a tool that we introduced during Q2. It allows smeshers to manage multiple PoST services on a single node.


Quick UDP Internet Connections (QUIC)

The QUIC protocol has been introduced. For a blockchain network like Spacemesh, this translates to improved network performance, better resilience, and reduced network overhead, ultimately leading to better peer-to-peer connections and enhanced decentralization.

Smapp now enables QUIC by default. We are working on relays that will assist with establishing the connections between natted nodes.


PoET Certifier

With go-spacemesh version 1.6.0, we introduced a new certification that will allow smeshers to use public PoET servers with more security.


Smapp

Several versions of Smapp have been released over the past three months, with improvements to ATX capacity and memory. All versions are available on the github repo, and the latest version is always available on our website.


Smesher UX

The UX experience of Smeshers has been lacking, and so we are taking measures to improve it with Smesher UX. These will include proof generation improvements, better proof status reporting, an ability to clear the node state, node identity management, and ATX builder improvements.


Traffic Usage Optimization

We have started working on reducing the traffic usage by the Spacemesh node.

Community


Spacemesh Anniversary Raffles

For the past almost nine weeks, we have been running weekly raffles in celebration of our upcoming anniversary, giving participants the chance to win prizes that can help them get started with smeshing (GPUs, HDDs, and gift cards), along with giving away Spacemesh SWAGPACKS.

Today we held the final raffle, but keep your eyes peeled for more opportunities to win.


Spacemesh World Challenge

The Spacemesh World Challenge is currently underway. We challenge our community to take photographs of themselves with a physical Spacemesh logo in interesting and unique locations around the world. Winners will be selected on the 24th of July.

Here are some of the submissions we have received so far, selected at random:

Events

We hosted and participated in several events over the course of the last quarter. These include:


Community Contributions

Our community remains prolific in their output of contributions to help fellow Smeshers.

In this update, we’d like to highlight the contributions which have provided the most utility to our community. (Please note that these are unofficial tools, which you use at your own discretion and risk.)

  • By @stizerg and @John: Updated SM-Monitor to v4.07 (You can set it up with this QR code:)

    - Now showing reward layers

    - Yellow for future layers

    - Green for layers within the past 1h

    - Gray for past layers

  • By @xearl4: For those brave enough to mess around with a CLI wallet, they have a new release of their patched smcli out. It now supports wallet spawn, wallet send, wallet balance and wallet sign subcommands.

The first quarter of 2024 was a momentous one for Team Spacemesh, which means that it was also exceptionally busy. We continued to roll out critical network updates and to make progress on the longer-term roadmap including the VM. We participated in events on three continents and continued to spread the word about what we’re up to and what we stand for.

The network continued to grow steadily and uptime has remained well above 99%, with no major downtime to speak of. In the first quarter of 2024, we continued to release regular development updates, and we’re happy that we now have enough bandwidth to resume our regularly-scheduled “big updates,” starting with this one.

Research & Development

Sync v2

Our previous sync implementation was not designed to handle the throughput we're now experiencing. We have re-designed it from the ground up, and many improvements have already been released:

  • Steps have been taken to boost the performance of booster nodes, which should result in a more efficient network synchronization experience.

  • The fetcher now supports a streaming mode, with continuous enhancements being made to the sync process.

Other improvements are still in development and will be released in the near future.


Quicksync

In order to simplify and expedite the syncing process for interested users, we rolled out the Quicksync feature. The full details are available in this blog post, but in summary quicksync allows users to download a snapshot of the current state from a trusted source (in this case, Team Spacemesh), allowing a node to sync within hours instead of days.


ATX Merge

This innovation aims to decrease the aggregate number of ATXes by amalgamating several of them, which will help with scaling up the network as it grows. Work on it has begun and we expect to implement it in the near future.


P2P Network Decentralization

To further expedite peer discovery, we have implemented relays within the p2p network. Relays and new discovery have been activated for all Smapp versions updated past 1.4.3.


Multiple PoST services per node

This is a long-awaited feature that was released with the Spacemesh v1.4. With this advanced feature, a node can now manage multiple identities and their life cycle. This reduces the amount of data that needs to be broadcast and fetched from the network, reducing the amount of data that needs to be stored locally due to only one database being needed for all identities, instead of one for each.


API v2

Development of this new and improved API is well underway, with v2alpha1 API being introduced with the 1.4 version of the node.


Distributed Verification

In order to reduce ATX validation load during the cycle gap, we allowed nodes to validate a random subset of PoST labels (instead of full validation), relying on others to find bad labels in the rest of the labels.This feature was released with version 1.4 and is enabled by default.


Explorer

We made the network explorer more robust, so that it’s now capable of handling a much higher load. It now also displays the correct Smesher ID in rewards in cases where multiple Smeshers use the same coinbase account.


Smapp

We released several new versions of Smapp over the past few months, with many notable improvements. These include the implementation of quicksync, and making statuses more informative and useful. We are currently working on enabling Smapp to display ATX sync progression.


Virtual Machine

In March, our R&D team met in Athens with the goal of defining and refining the Spacemesh VM design. After a long week of intense discussion and debate, they managed to reach a consensus on most of the core questions that needed to be addressed.

Lane Rettig has written a detailed explanation of the answers they landed on, and a summarized version of these decisions will be published soon.


Community

Ambassador Program

In December we launched the first phase of our Ambassador Program, where we began the selection process of our first cohort of ambassadors. In addition to a submission form based on qualifications and existing community contributions, we ran Zealy quests (please see link above for more details) which allowed all community members the chance to earn rewards, in addition to the role of ambassador.

The response to these challenges was overwhelming, with more than 1600 participants. As a result, sorting through all their submissions is taking some time. But we will announce the first cohort of ambassadors in the near future, as well as the details of how we will verify and distribute rewards to the challenge participants.

We will also soon introduce a program with tasks and monthly rewards for our ambassadors .
As the community grows, we will also be expanding the number of ambassadors, so be active, make content, be visible candidates and expect new recruitment to the ambassador program.

Watch this space for more opportunities.


Global Events

Our Dev Evangelist Lane Rettig attended several crypto conferences around the world to speak about Spacemesh and participate in panels, including:


AMA

An AMA with Lane Rettig (Dev Evangelist) and Noam Nelke (Chief Architect) was hosted by @altcoinist_com.

June and July were momentous months for Team Spacemesh.

After five years of ceaseless research and development, we reached genesis, and the network is alive and growing at a steady pace.

Our work continues, though, as we make improvements to the network, Smapp, and go-spacemesh, as well as continue development on future features like our Virtual Machine.

This is just the beginning.

 

Research & Development

Metrics

To better understand how smeshers are interacting with the network, so we can monitor things like network growth and overall health, we began to collect metrics. We only collect: versions, proving options, init size and init state. These are opt-out on Smapp and opt-in on CLI, meaning that our current statistics are very helpful estimates, but not comprehensive.

Presently, our metrics indicate:

  • 42558 completed PoST SU (storage units) -> almost 2.7PiB
  • 126930 total reported SU -> 7.75 PiB
  • about 5200 nodes

Protocol

P2P

We have migrated from our custom discovery to one from libp2p with Distributed Hash Tables. The primary reason is to benefit from hole punching and multiple transports support (quic, webrtc). 

Proving Difficulty

We temporarily lowered PoST proving difficulty on mainnet. 

We did this to prevent a certain kind of exploit, where an adversary with cheap processing power can replace some storage with much more computation, we've introduced a small amount of additional computation to the PoST proving process making this attack too expensive to carry out.

We had plans to offload this additional work and delegate it to other servers that can do it once for all smeshers they serve, but didn't think it was urgent.

After the launch of the Spacemesh mainnet we've talked to users and realized that the time this work would take on many users' actual setup would make it hard (sometimes impossible) to generate a proof in the limited time available for it.

As a temporary measure, until we can implement our long term solution, we're considerably reducing the amount of work required, so that no home smesher will be hurt by this.

As a consequence a powerful adversary could take advantage and slightly increase their power beyond their resource allocation. This would still require implementing some complex logic, putting in place specialized hardware and taking some statistical risk. This attack would also potentially be detectable.

To minimize the incentive to take advantage and the possible long term upside, we're committing to re-raise the difficulty within 10 epochs (5 months). We hope to finish implementing the delegation of this work much sooner, expediting the increase if the proving difficulty back to safe levels. But regardless of the time to roll this out—the temporary reduction will end automatically after 5 months.

This temporary change is part of our unwavering commitment to make smeshing at home effortless and effective.

Smapp

We implemented node functionality to stream the events via `EventsStream` api endpoint, and improved Smapp displays on the Smeshing screen that improves the usability and visibility.

The Smapp team is now preparing more configuration features to land soon.

Research

Post-genesis Improvements:

  • phased poets: nodes can work with multiple poet servers
  • poet service rewards: the community will be incentivized to run poet services
  • delegated k2pow and distributed verification: shorten proof generation for home miners

Virtual Machine

We have made solid progress on the plans to add a full VM to Spacemesh. A full overview of this design will be shared with the community very soon.

Community

Growth

Following genesis, our community has experienced a surge in growth, with 2000 more followers on Twitter, and 2500 more community members on discord. 

This is very exciting for us to see. We’re doing everything we can to ensure our community continues to thrive!

Contributions

Many community members have gone the extra mile to make life easier for other smeshers, so we decided to open a new #community-contributions channel on discord to compile all their work. Some of these awesome contributions include:

NOTE: All of these contributions are unofficial and haven’t been QAd by the Spacemesh team. 

Hackernoon

Spacemesh co-founder and CEO Tomer Afek did an interview with Hackernoon, where he discusses his love of surfing, and how this ultimately led him down the path to Spacemesh. He also explains what gives Spacemesh the ability to make a true “People’s Coin”.

Spacemesh has reached a very exciting milestone. Not only is our genesis candidate testnet holding strong, but it’s withstood two live updates without incident. 

Creating a novel layer one protocol from the ground up is a monumental undertaking, and it’s been a long journey to reach this point, with many stops and starts along the way. But now we can see the light at the end of the tunnel.

Thank you for taking this journey with us. It’s only going to get more exciting from here on out.

Research & Development

Testnet-05

Testnet-05 is live and stable! This mainnet genesis candidate is running with params that closely resemble those that will be deployed on mainnet. We strongly encourage all community members to join, initialize PoST storage and try smeshing to earn testnet coins in preparation for mainnet. There will also be opportunities for smeshers to win awesome gifts, which we detail in the Community section below.

Smapp & SMCli 

There is a new PoST initialization screen that allows Smeshers to configure advanced options.

Smapp autoupdate and forced auto-update is working as expected on the vast majority of the platforms. We deployed an update on Testnet-05 that tested this functionality, and it worked as expected.

We released the first production version of smcli, the Spacemesh CLI wallet tool. It allows generation of mainnet-compatible wallet files using BIP39 mnemonics as well as Ledger hardware wallets.

Protocol

We have been reworking POST from the ground up, using OpenCL based initialization. The new implementation is fully done and is integrated to testnet-05.

To ensure that the network is resilient, we’re working on providing robust “checkpoint recovery” which will help the network in the event that we encounter some showstopper bug. We hope to roll out this feature in an update to testnet-05.

Research

We were working on offloading k2pow (the proof of work required to generate PoST proofs) to poet servers in order to be more inclusive and friendlier to low end devices. We expect to ship this feature shortly after genesis.

We’re also in the process of switching k2pow to a different algorithm to level the playing field for Smeshers with less compute power.

Mainnet Readiness

We’re in the process of hiring a third party security research firm to help conduct audits of the Spacemesh code and perform security testing prior to launch. In addition, we’re continuing to improve metrics collection/telemetry and monitoring infrastructure so that we can keep a close eye on network health and respond immediately if something goes wrong.

Community

Spacemesh set up a booth at the Israel Crypto Conference in Tel Aviv, where CEO and Co-Founder Tomer Afek and Chief Architect Noam Nelke both gave presentations. It was awesome to meet with the broader crypto community and spread the word about Spacemesh.

We just completed the first Pre-Genesis Raffle, where smeshers won Ledger Nano Crypto Hardware Wallets, 2tb external harddrives, and one lucky smesher even won an MSI Gaming GeForce RTX 3060. 

There will be another raffle coming soon. If you want to participate, make sure to join the Spacemesh testnet and join our Discord server.

As we watch some of the world’s most entrenched and trusted financial institutions teeter on the edge of ruin, we feel even more passionate about our mission.

Ultimately, we want to offer as many people as possible the resources, freedom, and space required to make choices that aren’t beholden to an established system of power.  Spacemesh is on the cusp of releasing technology that will enable the masses to mine our coins. We are also setting the stage to build reliable, easy-to-use smart contracts, to serve as the basis of a bottom-up, collaborative value creation network.

One hurdle we've experienced is problems with Proof of Space data initialization. We found a bug, which we thought at first only affected Vulkan GPUs. But, after the release of Testnet-03, it became clear that it also affected NVIDIA cards. In response, our team immediately rolled up their sleeves and dived deep into resolving this issue. We also gained an overall efficiency increase in the process. 

While these results are indeed promising, we want to perform more testing before we launch, which has revised our estimate timeline:

  • New genesis candidate network launch: May 10th 
  • Genesis ~end of May

We take strength from you, our awesome community, for showing patience and continuing to lend us your support. 

 

Research & Development

Testnet-03

Our initial launch of the first genesis candidate network has provided us with extremely important feedback, and enabled us to fix a number of issues.

At the very beginning, there was a problem with POET that caused fast POETs to restart (nodes from different networks wanted to talk to them). We have now fixed the bug and updated POET servers. 

We also learned that some of the POST data that we initialized for tests on the 3090 GPU were invalid and contained incorrect data. We ran more extensive tests, and have started working on two parallel efforts to address these issues with the GPUs.

There was also one bad bug in Smapp that caused GPU VRAM overuse, which we are in the process of fixing.

SMCli

We have a beta release of a wallet tool that users can use to generate keys for genesis. A more feature-complete release, which includes support for mnemonic phrases, will be out very soon, and we expect to add hardware wallet support (ledger) shortly thereafter.

Getting this out required finalizing our interoperable wallet file spec, including how we encrypt wallet files, as well as the algorithm we use to convert mnemonic phrases into keys (BIP32/BIP44 derivation paths, BIP39 mnemonics) using ED25519. 

API

We refactored the API configuration and implementation to support multiple GRPC servers and services, and added a new feature to allow smeshers to update and switch between PoET servers. This included updates the tests, logging, and presets to use the new configuration and services

Optimization

One of the last changes inside the protocol is moving to an 8/56 proving algorithm, which should be about twice as fast on slow CPUs. This will allow Spacemesh to run on even slower CPUs.

Community

Our community has been instrumental in helping us to improve our protocol, and also in helping each other. As a thank you to those members who went above and beyond, we sent out a bunch of Spacemesh swagpacks.

There will be more opportunities to get your own Spacemesh swag, as well as other goodies, in the future. Just make sure to join our Discord server!

We are so very grateful for your ongoing patience, support and faith in the Spacemesh project and mission.

While genesis for Spacemesh is one more milestone and by no means a final destination, and while there is so much that remains to be achieved, Spacemesh has been in the making long enough without getting in the water. It’s now time to test the water. What this means is that the genesis date is around the corner, but also that we expect the early days post-launch to be bumpy.

In this update we seek to bring you up to speed on all main fronts:

1. Product and Roadmap
2. Issuance Schedule
3. Testnet
4. Vision for Cultural Evolution

Introduction

For a crypto asset to ascend to the value of Bitcoin or Ethereum at minimum, the following three ingredients must be present:

  1. Novel and profound technological breakthrough

  2. Novel and profound social/political agenda

  3. Novel and profound distribution model to reach the masses (since early mover advantage is gone)

#1 — Tech: The technological break Spacemesh makes from traditional DLT protocols is radical, an entirely qualitatively different means of achieving consensus in the permissionless setting, which (if successful) promotes higher quality of decentralization and low barrier to entry.

(*) Read here (7min read) on the Qualitative aspect of money systems.

#2 — Social: Spacemesh’s social mission and cultural agenda is even more novel and radically different, on the following accounts:

  1. Spacemesh values and social mission are not to be measured in popularity, because we only do what we do for the mission we truly believe in. So supporting us, by purchasing or mining Spacemesh coin, function as means of supporting the very ideas we stand for. In so doing, Spacemesh is the first to break from the functional (values neutral) means of presenting cryptocurrency infrastructure.

  2. Alongside the technology, we offer a comprehensive, scientific (anchored in evolutionary biology), scalable to humanity-wide, solution for an entirely new mode of organization, the ‘Messy Federation’ of the ‘Biological Future’, demonstrating robust qualitative advantages on every possible axis, over the decaying neoliberal order. Read more on ‘Messy Federation’ here (11m. read)

  3. In accordance with this, Spacemesh community building has been focused on quality over quantity since its inception, signaling to the few who care to listen in these frequencies to begin with. We already see the fruits of this approach, as a tight-knit community, composed highly aligned like-minded people, stands to benefit most from non-overpopulated genesis, while evolving into bedrock for
    our wider community.

  4. The team of cryptographers and engineers in Spacemesh is of the highest conceivable quality and unity and represents a promising attempt to launch a 3rd contender to the ETC/BTC PoS/PoW duopoly.

#3 U.B.I. Distribution:

In May of 2023, a unique date will occur, when the open source codebase of Spacemesh cryptocurrency will have its genesis moment. The uniqueness of this date stems from the ability of ~1 billion people (who already have the minimum hardware) to participate, risk-free, in the fair distribution of a cryptocurrency. Not by lottery nor by money, but rather by guaranteed coins, every epoch, from their gaming PCs at home.

Following this date, since no one has any $SMH (Smesh coin), the only way to get it will be to mine it yourself. That is, until enough supply has been mined and accumulated by exchanges to allow for trade. During this period, the distribution of $SMH amongst miners is both extremely fair and entirely out-of-spacemesh’s-builders-control.

In the background a few trajectories are worthy of attention, as if the case for material logic (the rationale for cryptocurrency) needs even more support:

  1. There is growing scientific convergence and a body of evidence to suggest, for example most recent Nobel committee decision, as Wittgenstein predicted, that spacetime and its contents are NOT fundamental reality, a complete break from the “I think therefore I am” Cartesian picture, so dominant to human thinking for the past 400 years.

  2. As a result, the establishment “end of history” paradigm is facing problems all over the world. Many ordinary people are getting frustrated with relativistic logic, narrative manipulation, and campaigners constructing fake reality in the media.

  3. We believe, and will demonstrate if given the trust by a large community base, that there is an entirely new game for humanity to play collectively, and an entirely new way for humanity to make sense and discover deeper truth collectively, and an even newer way for humanity to signal what’s virtuous and increasing fitness to one another.

  4. While A.G.I. (non biological computation general intelligence) yet struggles to cross the Rubicon. To borrow the words of the great Eliezer Yudkowsky, the most important thinker on the AGI alignment problem: Humans must never let go of the steering wheel (and let the machines drive) or else we’ll certainly crash the future.

The true calling of decentralization and cryptocurrency is clearer than ever!

Lastly, facing the criticism Spacemesh building should not have taken so long, we find it imperative to emphasize the timelessness of that which can not be measured empirically: hill climbers and valley crossers require two distinct qualities, and while turbocharged execution might appear on the surface effective, that which is built to last must be ever-so-carefully constructed and reconstructed, and may thus appear confused to an uneducated eye. If Spacemesh will succeed, let it remind us that greatness is NOT about ‘moving fast and breaking things’.

The opportunity for permissionless, decentralized, environmental and programmable people’s crypto, remains up for grabs.

Product & Roadmap

Spacemesh continues to define its role in the emergent cryptocurrency industry as the “onboarding of the rest of us”; Thereby our axes of optimization remains as they have been from day zero:

Reduce Barrier of Entry: Allow anyone, anywhere, without requiring any special equipment or prior knowledge, to join the network and receive a monthly allowance of Smesh coin.
Collaboration Focused: as an antidote to the extreme individualism period we live in today. For home miners, collaborations should manifest as most feasible path to build economic independence, turning a small monthly allowance into regenerative flows.

Node — The core team has completed implementing the final critical components of the node required for the mainnet launch. As our main focus is on home miners with older hardware, the team identified and addressed various performance issues affecting speed, memory, networking, and storage over the past few months. The team has worked methodically to address these issues, solving some on the implementation level, while others required minor or even significant protocol adjustments. A few issues were temporarily patched until more substantial upgrades can be implemented after the genesis launch.
The node is currently undergoing final adjustments and testing before it can power the Spacemesh mainnet and cater to the long tail of users.

Smapp — To make Spacemesh more accessible to everyone, we have developed a user-friendly, secure, and powerful app with a beautiful interface that aligns with the Spacemesh brand. The team has invested significant effort in stabilizing and improving the app to make it as useful as possible while adapting it to the latest changes in the node and protocol. SMApp is a versatile tool that enables users to manage their Spacemesh node and wallet with ease. It can handle various responsibilities including securing the wallet with a passphrase or hardware device, installing and upgrading the node, guiding users through the PoST setup process, and much more.

Infrastructure — Our infrastructure is now battle-tested and capable of launching and maintaining thousands of Spacemesh nodes in a managed environment. The team has implemented real-time monitoring, alerting, and analysis tools to effectively monitor running networks.
Furthermore, we have stabilized and improved our testing infrastructure, increasing its robustness and consistency. This improvement enables us to more easily and safely accept pull requests from the community and make Spacemesh a true collaborative effort!

PoET — While the PoET protocol has been in use for several years, the team recently focused on making the implementation production-ready. This involved optimizing the code for efficiency and building a physical server capable of running the protocol at peak performance. We benchmarked various types of hardware and created a recipe for a high-performing PoET server. We then used this recipe to build two additional, redundant servers in different locations to serve as Spacemesh’s proof-of-elapsed-time backbone. We will publish the hardware specifications for those interested in building their own servers. To optimize proof execution, we modified or rewrote key areas of the software implementation. Our analysis of the PoET runtime revealed that the main CPU core spends minimal time performing tasks other than calculating hashes. PoET hashing utilizes specialized CPU instructions, similar to built-in ASICs. Thus, we anticipate no significant performance gains in the near future.

What’s next? The Spacemesh roadmap outlines several areas for improvement including enhancing security, adding desired functionality, and improving efficiency and performance. The following is a sample of issues that we intend to address in the short term, once we have a stable running network.

User Deployed Code — Currently, we have limited the functionality of accounts immediately after genesis to precompiled contracts provided by Spacemesh. However, we recognize the importance of introducing user-deployed code to the Spacemesh ecosystem. To facilitate this, we plan to keep the base layer simple and introduce a decentralized rollup that will be independent of the base layer. This rollup will be based on the EVM framework, providing a familiar and capable platform for users to build on.

Separate Executor Role — In line with the industry-wide movement towards more modular blockchain architecture, we are also exploring decoupling transaction execution from consensus. This involves allowing a subset of smeshers to specialize in transaction execution, which would reduce the load on most smeshers, lower the minimum system requirements for non-executors,
and still compensate executors for their work. This approach aligns with our commitment to reducing computation and power consumption network-wide.

Scalable Hardened PoET — To ensure the stability and security of the PoET service regardless of the load placed on it or attacks carried out against it, we have designed an improved version of PoET that is a “drop-in replacement.” This new version of PoET is infinitely scalable and less susceptible to attacks, and it exposes the same API to the system as the current version. In the long term, we plan to incentivize the PoET service to open it up for competition, but for now, we are focused on ensuring that the running PoET is stable and secure.

Dynamic PoST Space Allocation — Although the protocol allows for increasing and decreasing the allocated PoST space, the current node and SMApp lack the functionality to perform these actions. We anticipate that this will be one of the most requested features from the smesher community, and we are actively working to implement it in a user-friendly way.

Pruning of Outdated Objects — One of the most important post-genesis tasks on the roadmap, and one that’s especially important for the scalability and longevity of the protocol and the network, is pruning: making it possible to selectively remove data objects, such as old blocks and state, from running nodes. While we have designed many of the objects used by the protocol to be prunable for efficiency and security purposes, we still need to define when and how to perform the pruning. This will not only help save storage space but also prevent smeshers from experiencing disk overflow in the event of a spam attack. We believe that implementing this feature will help make the Spacemesh network more resilient and efficient in the long run.

Issuance Schedule

In setting out to achieve these economic goals (as in so many other areas of the project) we are primarily inspired by Bitcoin. While there will never be another successful fair launch like Bitcoin, we believe we’ve come as close as possible to this ideal. We’ve started with Bitcoin’s economic model, and made three important tweaks.

  1. Rather than having abrupt “halvenings”, Spacemesh issuance decays predictably and gradually with every layer.

  2. Whereas Bitcoin has a half-life of about four years, the half-life of Spacemesh issuance will be about 29 years. This means that, while the last full Bitcoin will be issued around 2140. the last Smesh coin will be issued hundreds of years after genesis, in around 2899.

  3. A small portion of Spacemesh issuance, 6.25% of the total, flows into “vaults” for early investors and builders, with multi-year vesting.

Testnet

Spacemesh genesis release candidate #1 is running in testnet and configured with final mainnet parameters. It is now almost fully simulating the experience of mining on mainnet.

Testnet-03 Progress Report

So far, we have observed a few issues:

  • April 12th, 2023: we discovered a problem with PoET that caused some of the nodes to not evenly register to the PoET servers (some poets got fewer members than others). This has been fixed.

  • April 16th, 2023: we located another issue inside the go-spacemesh code that caused invalid timing of generating the POST proof, causing a substantial number of nodes to miss the window for epoch 2. The fix for that is incoming, and we will use the “force update” feature that will force your Smapp to restart and load a new version of components. Sadly, that will cause some nodes to miss rewards for one epoch. Anyone who uses go-spacemesh directly should update manually.

Besides that, we spotted a few issues with Smapp that were fixed with releases of 0.3.1 and 0.3.2. Some of them caused problems with starting post-initialization etc. We expect 0.3.2 to be much more robust at these basic operations.

Please upgrade the Smapp whenever you see a popup in the smapp saying that there is a new version, as this will ensure optimal functioning.

Other notable incoming changes to testnet-03

Vision for Cultural Evolution

We strive towards a forward-looking, decentralized yet coordinated inter-group collaboration.

Spacemesh is determined to become the ideal infrastructure for supporting the Messy Federation Political Framework — Crypto-enabled, self-organizing, well-integrated: a superorganism composed of superorganisms, nested and meshed together, vastly more resilient and prosperous than any of their individuals could possibly dream. Crisscrossing and switching between different modes of organization, capturing meaning together.

Spacemesh’s technological mission is to build the world’s most decentralized, robust, sustainable and programmable people’s cryptocurrency. Suitable for robustly and qualitatively support of such Messy Federation. Giving humanity an immutable ledger of the past which cannot be altered by those who want ‘progress’ at any cost; A necessary architecture to serve as a foundation stone for a humanity that is consciously evolving itself. To free us from our post-Enlightenment obsession with finding data-driven static solutions,

On such a foundation we seek to bring to life Spacemesh’s social mission for a new and improved system to collectively satisfy our mutual needs, without devastating the planet or behaving sociopathically. A springboard for a revolution in human values, so we can mindfully adapt ourselves, our culture and our economy, as an inter-connected, complex living system; giving groups the ability to, through technology like smart contracts, enact
Ostrom’s eight principles in a far more streamlined and efficient way.

Code freeze is so close that we can almost taste it.

Research & Development

Optimization


As we move towards code freeze in preparation for genesis, a lot of our energy is focused on optimization. We’ve now fully changed our hashing function from SHA256 to BLAKE3, unifying hashing across the protocol. BLAKE3 has the benefit of significantly faster processing speed when compared to SHA256.

Go-spacemesh now also has more refined layer processing.


Protocol

PoST development continues apace, including a rewrite to Rust for more effective AES usage. We expect that these changes will lower CPU requirements..

In the Hare protocol, we’ve adjusted the behavior of the non-smeshing nodes to make sure that they fully participate in the network.


Smapp

For maximum cross-platform accessibility, we now have an AppImage for Linux distribution, ARM support for Linux and MacOS, and full support for native Apple Silicon. To improve convenience for smeshers, we have validated and improved the auto-update mechanism.


Testnet

We have released new test networks 323 and 324. We have placed the first fast PoET server inside a datacenter and we’re working on hooking it up to the testnet. We’re still in the process of securing our bootnodes for the mainnet (including but not limited to firewalls and DDoS protection).


Research

Our research team gathered in Gdańsk, Poland for a research summit focused on defining the post-genesis Spacemesh roadmap. We laid out a vision for a “Spacemesh 2.0” with, among other things, a full-featured VM with layer two support, more efficient PoST proofs, more resilient PoET infrastructure, and a revamped, more efficient Hare. In addition we also took the opportunity to finalize a few remaining, important topics for Spacemesh 1.0 (the upcoming, initial genesis release candidate). A formalization of the genesis version of SVM is in progress.


Mainnet Readiness

We’re finalizing the genesis specification for PoST proofs. We’ve found a way to significantly improve the speed of proof generation and verification that will lower the final device requirements. The current generation of the testnet is still running with an older implementation, so estimations from the current networks are outdated. We will also provide a tool that you can use to assess the PoST performance of a system that should prove useful for capacity planning.


Community

We have added several more episodes to our Bite-Size Talks series, featuring Noam Nelke, Spacemesh’s Chief Architect. In the past month, we covered: Genesis, Layers, and Epochs, Rewards, Explained, the What Does "Fairly Distributed" Really Mean, why the world Does The World Need Another Cryptocurrency?, What Could Possibly Go Wrong?, Can Spacemesh Development Be Lean?, and Why Does Crypto Need Proof?.

For many more informative videos, be sure to subscribe to our Youtube channel.

To show our appreciation for all the help that our community has provided in making our code the best it can possibly be, we sent out swagpacks to all those who’ve reported bugs and made suggestions.

Keep being awesome, smeshers!


The development process is always complex and unpredictable, doubly so when you’re developing a novel layer one protocol with a truly novel consensus mechanism like we are at Spacemesh.

We're gradually adjusting testnet parameters (min/max PoST storage size and proof complexity, length of epoch, PoET params, etc.) to more closely resemble the target mainnet parameters. In the process, we're discovering new bugs. This is ultimately a good thing, since it means that mainnet will not have to contend with these issues, but they do unfortunately mean it’ll take a bit longer to do genesis and launch the mainnet.

In light of these new challenges, we anticipate that genesis will occur late in March 2023.

 

Research & Development

PoST Proofs


One of the bugs we ran into is the time it takes to generate and validate PoST proofs (the core proofs that underlie proof of spacetime). We had made a few assumptions about “fast” hash functions, but never tried testing them to generate proofs of large amounts of space—on the order of gigabytes or more. We're calibrating the parameters and investigating several candidate hash functions (SHA3, AES, Blake3, Siphash) with different performance characteristics, along with their security params/cryptanalysis, to make sure they're appropriate, secure, and fast enough. This is harder and is taking longer because we need to test these params across an array of hardware and software - Mac, Linux, and Windows, on Intel and ARM, old and new processors, etc., to make sure it supports the wide range of hardware that we expect smeshers will be running.

Due to the resource demands of the protocol in its current form (bandwidth and compute), you'll need relatively modern hardware with a strong internet connection to smesh reliably in the beginning. We have a lot of ideas and plans for how to reduce these requirements over time and will prioritize that as soon as genesis has happened.

Hare and equivocation proofs


Over the course of many testnets, we came to realize that there are three types of faulty messages in Hare:

  1. Missing message: a message was expected never arrived.

  2. Invalid message: when the signature of a message is not valid, or the message binary structure is incorrect or the eligibility proof is incorrect.

  3. Equivocation: when the same eligibility is used to produce two (or more) different messages.

That third case is the most dangerous one. Spreading equivocations is the primary way of attacking Hare protocol, because any other forms of attack are very easy to filter out. For this reason, we’ve been shoring up our equivocation defense to make sure the Hare protocol is not vulnerable to such attacks come genesis.

We’ve also restored passive Hare participation, so that Hare proceeds even if the VRF nonce is not present.

There have been a suite of improvements to PoET server Proof of Sequential Work: hashing speed, benchmark, and much more. We’ve also improved Node to PoET communication..


Wallet Format


We’re finalizing our wallet format, which includes finalizing a few small but important details about choices of elliptic curve, cipher, and signature scheme, wallet file format and encoding, etc. This also involves developing a new library to be implemented across the Spacemesh ecosystem for generation of new wallets and keys, such as by early Spacemesh supporters to generate their initial keypairs. This library will also be used to develop a CLI (command line) tool for wallet generation. Since SMRepl, the previous CLI tool, is now fully deprecated, we’re building the tool in a modular fashion and expecting that it’ll be expanded into a robust CLI tool that can be used not only to manage keys and wallets, but also to manage a running Spacemesh node.


PoET


We have spent significant time improving PoET stability, and we have been focusing on defining final deployments and final hardware for PoET servers. The hardware is pretty much fully finalized—we’re just fine-tuning the last remaining efforts. We have also fine-tuned performance of PoET and decided to increase the difficulty of hashing from 100 hashes per leaf to 400 hashes per leaf.


Account Model


On the research front, we spent some time considering different schemes for smart contract address generation, looking at algorithms used by other networks and considering the uniqueness of the Spacemesh account model. We settled on a scheme whereby template authors can choose which elements of “immutable state,” including the template deployer’s address, will be hashed into the final, deployed contract address.


Consensus


Exploration began into ways to bring about full consensus on the active set in Hare, or alternatively, novel Hare designs that (like Tortoise) don’t rely on full and perfect consensus. (Read more about the design considerations in this recent article.)


Hash functions


We revisited the question of which hash function is best-suited for general use throughout the Spacemesh protocol and settled on Blake3. We’re exploring available libraries with hardware acceleration. (Note that other hash functions, such as SHA256 and scrypt, will continue to be used in places like PoET and PoST.)


Updates


In the interest of making the update process as painless as possible, we’re exploring ways to make the random Beacon protocol more resilient against scenarios where many nodes restart mid-epoch, such as after a software update, as well as to improve the update process more generally.

Spacemesh 2022 End of Year Update

2022 was momentous and transformative, not just for Spacemesh but for the blockchain and crypto industry as a whole.

We saw the expansion of government overreach in the form of sanctions against Tornado Cash, as well as the logical consequences of all the hyper-centralized, FOMO-based infrastructure driving much of the existing crypto industry: the collapse of FTX.

But this only served to highlight the importance of Spacemesh’s mission. In order to bring blockchain to its true, revolutionary potential, we need something that is truly decentralized and truly censorship-resistant.

Spacemesh has also undergone a great many internal changes this year, where we said goodbye to many team members while welcoming many new ones. This has presented us with a great many challenges, but also opportunities. It is friction, after all, that drives us closer to the truth—and to our true potential.

2023 will be even more momentous, with genesis on its way.

Read the full update here.


As our industry wraps up what is arguably its worst year yet, and doubts resurfacing about the merits of blockchains and cryptocurrencies, we are more certain than ever that the missing ingredient is the added resilience of decentralization. As a result, Team Spacemesh’s determination is on the rise. This is the ideal atmosphere for launching our coin.

In November, the Spacemesh team gathered in Lisbon for four intense days of in-person workshops and discussions. This was an important touchstone, allowing for our distributed team to meet face-to-face and get on the same page about our values and goals, and our plan of attack. We discussed a wide-ranging set of topics including outstanding research challenges, development progress, devops, community and open source strategy, and everyone’s World Cup picks!

One important outcome of these discussions is that our original projection of genesis by December is no longer realistic because testing is taking longer than expected. Development is going well and we are very nearly code complete, and testing continues apace. With the help of our community on the testnet, we’ve identified many bugs in need of fixing—which is a very good thing! (That’s what testnets are for.) In light of all these factors, our most up-to-date estimate for Genesis is the end of January 2023.

We’ll keep everyone in the loop as we get even closer to Genesis. For the most frequent updates or to ask questions, join us on discord.

Research & Development

We had an extremely engaging strategic conversation regarding our VM choice and programmability plan in Lisbon, based on recent learnings from Ethereum and other projects. We’ve decided to explore layer two options including rollups and EVM compatibility. Expect a comprehensive announcement of our plan soon.

On the protocol front, work on PoET server resilience continues, in particular allowing one submission of PoST per miner per round of PoET service.

We completed measures that will allow the network to recover from a 30/70 split, and fixed many issues, including: handling multiple block certificates, completing optimistic filtering conditions, repairing PoST initialization on Macs, improving performance, and fixing data races in PoST initialization.

In the beginning of November we released Smapp v0.2.7 with huge breaking changes, including new transactions and accounts structure and BECH32 addresses. By the end of November, Smapp supported the latest version of go-spacemesh.

Here are all the Smapp releases from November:


These releases coincided with iterations of the Spacemesh open testnet, and the latest iteration—network 310—has support for GenesisID.

On the research front, phase 1 of our Hare simulation has been completed, meaning that we’ve successfully tested unreliable network conditions. The data we collect from these tests has helped us to optimize the Hare protocol in areas such as equivocations defense and data volume. We are also making progress towards final mainnet parameterization, including setting difficulty for the Proof of Work Protected Setup-Verifiable Random Function.

POPS-VRF is very important to prevent malicious users from creating multiple identities to artificially meddle in consensus, by implementing measures such as looking for a nonce to satisfy a given difficulty during PoST initialization.

And in preparation for Genesis, we’re working through a detailed plan on how to get a minimum amount of storage space online right away when the network goes live. There are many details to work out, including how to cheaply acquire or rent GPUs, and how to pipeline PoST initialization proofs from GPUs to cheaper long-term storage. This exercise is extremely helpful in thinking through every small detail that will be involved in genesis, and putting all of the steps in the right order. It has also involved creating some custom software, including a standalone version of gpu-post for testing GPU performance.

The Plant the Future drop challenge has come to a close, with 1250 trees planted!

This accomplishment was only possible with the help of our awesome community, who persevered despite the testnet network not always being the most reliable.


Volunteers came forward to translate Spacemesh blog posts into multiple languages, including Italian, Russian, Estonian, Mandarin, Japanese, & Vietnamese, with more languages to come. We are compiling all these contributions into a twitter thread.

And finally, Spacemesh’s CEO and co-founder Tomer Afek released a new blog post exploring the factors leading to our increasingly radicalized and polarized world, and how decentralization is vital to fixing it.

There are many arbitrary metrics that you may choose to measure the success of a project—number of users, revenue, stickiness vs. churn, etc.—but, at the end of the day, what's really the best one?

We think the answer is: joy. Does the thing you build and ship to your customers spark happiness for them? How would they feel if you took it away from them tomorrow?

Interestingly, this is not a metric that most crypto projects talk about. They tend to focus on things like transaction throughput per second or VC dollars raised (or lost). These are poor proxies, at best, for what really matters. Ultimately, it all comes down to this: do users enjoy using your product? Does it bring them joy? Does it have a materially positive, fun impact on their lives?


If we’re absolutely honest with ourselves, it seems that vanishingly few crypto projects, whether base layer infrastructure or applications, have crossed this threshold so far. Partly this is because of the intrinsic headaches that crypto still entails, such as managing keys, onramps and offramps. These vital considerations mean that crypto solutions are rarely the fastest or easiest. On the other hand, it speaks to something even more fundamental: money, and fancy financial primitives, simply do not bring joy to most people. NFTs are a little better, since they’re collectible art, but most NFTs are less about sparking joy and more about creating FOMO (i.e., its opposite).

And this is not just a philosophical exercise! This has serious, real-world implications on our trade. Users were willing to fight for Uber when it played fast and loose with regulation and entered unfriendly markets, because using it in the early days was such a joyful, novel experience. How many people would be willing to fight on behalf of crypto today?

As we’re contemplating what we’re building, why, and how, we’d do well to learn this lesson. Everything we build—every line of code, every byte thrown across cyberspace, every word and every handshake—should be motivated above all else by the pursuit of joy and fun. If we manage to deliver delightful, novel experiences to people around the world, the rest will work itself out. And if not, then it doesn’t matter how decentralized we are or how many transactions we’re processing: the world will never really care very much.


Research & Development

Come mainnet, it will be extremely important for our network to be resilient. We’ve been improving this resilience with the implementation of multiple PoET server support within a single node. This will provide redundancy in case one of the servers fails.

We’ve been taking measures to ensure that the network can recover from partition. For example, by making sure that in the event of a network rejoin following a 30/70 split, the 70 nodes will remain confident, and the 30 nodes will do a full vote count on all the nodes from both sides of the split—which means all the nodes will reach the same mesh hash.

In Tortoise, we’ve also increased the number of layers that can be kept in memory. This will allow us to use that stored data in the process of self-healing. (E.g if we can keep 10 000 layers in memory, we can heal a partition that started 10 000 layers back.)

Shoring up security is likewise imperative, and that’s why we’ve been focusing on the security of both the protocol and Smapp. On the protocol side, we’ve started work on the implementation of Proof of Work Protected Setup-Verifiable Random Function, which will prevent malicious users from creating multiple identities and thereby manipulating consensus.

We must also prevent adversarial users from including any number of ineffective blocks (containers for transactions, so they can be very large). We have addressed this issue with deferred block fetching, where we allow smeshers to syntactically validate a ballot even when they don’t have the referenced blocks. This will prevent the ineffective blocks from being stored on the mesh.

In Smapp, we found a vulnerability that uses a constant IV (initialization vector) across multiple encryptions, which is quite dangerous and will be addressed. We also noticed that authenticated encryption was not being used by SMAPP, so it would be impossible to tell if the wallet file was corrupted or altered before trying to parse the decrypted wallet data. To fix this, we defined new encryption and key generation parameters for the SMAPP wallet, to make sure the encryption key derived from the user's password is safe and that the actual encryption process of the wallet uses secure nonces.

A new public testnet will be coming very soon. This represents a huge step forward in terms of the maturity of our code, with the testing done by our community proving to be invaluable. Once this network is launched, we will give an update about the network progress and status every two weeks. (Changes in the code will render the current dashboard and explorer obsolete, but they will be back as soon as possible.)

This network release is accompanied by a new Smapp release, which includes support for the new transaction structure, HD wallet support (which paves the way for hardware wallet support in the future), autocomplete for contacts, log rotations to reduce log file size, and a host of other improvements and bug fixes.

On the research front, we’ve completed the first version of a Hare simulator, which is used to measure Hare resistance to bad network conditions and attack scenarios. A more advanced version of the simulator (based on “discrete event simulation” pattern) is in development, and will allow for more detailed simulation of bad network conditions (such as messages getting delayed) and for testing balancing attacks. These simulators will provide us with vital lessons and feedback which will then be applied to the production code.


Community

The Spacemesh community is planting trees!

As part of our “Responsible Energy Use” social cause, we started the “Plant the Future” drop challenge. We tasked community members to smesh testnet coins and send them to a specific account address. For every 1000 testnet SMH they sent, Spacemesh committed to pay for a tree to be planted. And for every 50 000 SMH, we doubled the number of trees.

This drop challenge has been put on hold for now, to be continued when the new-and-improved public testnet returns. In the meantime, we planted the 250 trees already smeshed by our awesome community.


Crypto is moving in a direction where powerful actors like nation states and international banks are increasingly compelled to pay attention, and often for good reason. There are indeed bad actors making use of cryptocurrencies to nefarious ends, so it’s understandable that the US treasury and other nation state actors are beginning to respond aggressively.

But while we agree with their goals, we disagree with their tactics, because privacy is a non-negotiable human right. We're entering uncharted territory, and it's incumbent upon us as visionaries and builders to emphasize the positive, socially constructive use cases of cryptography, blockchain, and decentralization. We need to show regulators the potential for crypto as a force for good, as opposed to the international crime syndicates and money laundering that currently have all their attention.

Understandable motives aside, many of the threats that the early cryptocurrency pioneers predicted are now becoming realities—the sanctions against Tornado Cash being the most notable recent example. We’re certain it won’t be the last.

The easy, "happy hacker cypherpunk" days of crypto are sadly coming to an end, and more is at stake than ever before. As regulatory measures pick up in pace and severity, as “the tide goes out” on the halcyon beginnings that many knew could never last forever, we’ll no doubt see who's been swimming without any swimming trunks this whole time—that is, which projects are DINOs ("decentralized in name only")!

Recently, Ethereum successfully transitioned from Proof of Work to Proof of Stake via the Merge. While this is certainly good news for the energy-strapped residents of planet Earth, it remains to be seen if Ethereum will be able to maintain its edge and prevent censorship now that a handful of large, regulated actors control the majority of its stake.

This is why we here at Spacemesh are compelled by our vision of a truly decentralized cryptocurrency. And why we’re doing everything in our power to see our mission through as soon as possible.


Research & Development

We added a dependabot that automatically creates PRs for Spacemesh when any of its dependencies is updated. From now on, fixes will be integrated more quickly, which will increase our efficiency going forward. It will also check and alert us to changes made by the Go community, bringing us closer to open source readiness.

Efficiency is a concern at every level of the protocol, which is why we’ve optimized the manner in which ATXs are broadcast. In the past, every ATX was broadcast with the NodeID that created it. But this was redundant, because the NodeID could be derived from the ATX’s data and signature. So by removing the NodeID from the ATX broadcast, we reduce the amount of data transmitted between nodes without losing any of the necessary information.

We’ve made major improvements to the Hare protocol, ensuring that Hare output for each layer is now certified and distributed in the network. Hare certifiers certify eligible messages through “gossip” after a block is generated. We’ve refined the process by which a node generates a Hare certificate for that layer when it receives enough certify messages, and fixed a bug where Hare sync flow didn’t work.

On the SVM front, we’ve completed support for multisig wallets. Multisig wallets use two or more private keys, either independently (in case one of the private keys is lost, or the wallet must be accessible to multiple users) or in tandem (to ensure extra security through 2-factor authentication).

Research into the SVM specification draft continues, as part of our ongoing efforts to create a complete vision of SVM functionality. This will serve as a strong foundation for the introduction of smart contracts post-genesis.

Smapp has received two new features: node auto-launch prior to unlocking the wallet, and log rotation. The latter is especially important during testing, as log files are very comprehensive and tend to get very large.

We’re also researching mitigations of two potential denial of service vectors in the Tortoise protocol:

  • Block-level spam: a category of DoS attack where an adversary invents a large number of fake block identifiers and drags the network into expensive work of downloading them (which will eventually turn out to be a waste of time and resources). We invented a new defense mechanism for such attacks, based on “dangling pointers”, which requires changes in the block fetching mechanism.

  • Ballot-level spam: a category of DoS attack where an adversary gossips a large number of ballots reusing the same eligibility (i.e., commits a protocol fault called “equivocation”). We’ve worked on a new defense mechanism to stop such attacks. The protocol changes mostly involve pruning bad ballots.

Other areas of research include redesigning the PoET API and rewards mathematics.

  • PoET servers are to be maintained in a decentralized way, i.e. anyone can run such a server. This raises a question of malicious/unreliable PoET servers. We are working on suitable changes to prevent such malicious behavior.

  • Smeshers receive regular rewards from both transaction fees and block subsidies. Both of these are now fully specified and implemented.

Community

As part of our efforts to empower our community across the globe, we reached out to various community pioneers to translate Tomer Afek’s open letter to the Spacemesh community into several languages. These include: Chinese, Japanese, Indonesian, Ukrainian, Russian, and Italian.

More translations will be coming in the future, reflecting the truly international nature of the Spacemesh community.

We also have some passionate and creative developers in our community. Recently, andreiv.eth#4775—one of our Community Pioneers—took the initiative to develop spacemeshlib, a tool to help other developers get started on 3rd-party development with Spacemesh technology. We extend a huge thank you to Andrei, and invite all who are interested in getting hands-on with Spacemesh to check it out!

Our mission at Spacemesh is to build the most decentralized cryptocurrency that’s ever existed. With every passing week, we become more aware of how crucial this mission is.

In order for cryptocurrencies to live up to their real promise, they have to be censorship-resistant. While the underlying network, Ethereum, is decentralized, many of the applications running on it, including stablecoins like USDC, are not. Circle’s recent blacklisting of Tornado Cash ETH addresses in response to sanctions by the U.S Treasury has proven that, without true decentralization, censorship resistance is just a myth. And Ethereum’s imminent transition to proof of stake risks making it much more centralized, putting censorship resistance truly at risk.

This is why our work to build a truly decentralized, permissionless, censorship-resistant cryptocurrency platform is so important.

With this in mind, we’re very conscious about the factor of team cohesion. Our development team is fully remote and international, so this is a particular challenge for us. That’s why, in July, we brought our development team together in person so that they could get to know one another, helping them perform better as a team instead of a set of individuals. We also held a hybrid workshop session to discuss the most pressing problems that we see and came to a consensus on how to address them.

We’re also looking to expand our team with new hires: a golang developer to join our core team, and a Developer Relations Evangelist who will lead the charge to communicate Spacemesh’s technology to the wider world and make it accessible for developers in our community.

Research & Development

As our team transitions from an intensive R&D phase to a testing phase, where we thoroughly test our code and infrastructure to prepare for genesis, testing tools become more and more important. To this end, we’ve created tools for more advanced testing of the network to ensure that it remains stable indefinitely. These include automating things like submitting transactions, adding/deleting nodes, verifying that nodes are synced, and introducing unpredictable “chaos” conditions. These tools will enable us to efficiently conduct the sorts of tests we need to prepare for genesis.

It’s essential that we find as many bugs as possible, and deal with the bugs we find with our automated testing tools. To that end, we’ve started regular, larger scale, and long-running tests to flush out bugs, and started adding more metrics for debugging performance and general monitoring.

To make Spacemesh as future-proof as possible, we’re also in the process of decoupling execution from consensus. In essence this means that the parts of the Spacemesh node that are responsible for executing smart contracts are totally separate from the parts that are responsible for coming to consensus on the canonical, ordered set of transactions in each block. While all smeshers will perform both tasks at genesis, this decoupling makes it easier to introduce different roles into the protocol in the future, and embrace a more modular future. For more on the topic of modular blockchain and why it’s central to the Spacemesh vision, we suggest watching this talk and reading this recent article by team member Lane Rettig.

Smapp development continues apace! We’ve released version 0.2.6, which comes with a new “report issue” button (to help the community to inform us of those bugs we’re looking for), as well as a host of bug fixes, such as recovering wallet from mnemonics and showing rewards in the transaction log. Now we’re working on catching and showing proper messages on system errors (which is mainly a problem on Windows), and starting up the node and smeshing on the Smapp startup if it was already configured previously. (For example, if Smapp is toggled to auto-start once the user’s computer boots up, then after system reboot it should start smeshing automatically, without a requirement to unlock the wallet.)

Our research team made significant progress finalizing the design of various aspects of the PoET protocol. As a recap, Spacemesh relies on PoET (proof of elapsed time) servers, which are separate from the main Spacemesh node, to allow smeshers to generate and submit proofs for the time part of the proofs of spacetime that underlie the protocol. In the past, there’s been difficulty in aligning PoET execution with protocol epochs, meaning that the PoET server completes the proof and then idles until the next round is supposed to begin. In mainnet, we'll want to control PoET more tightly by setting a precise completion time, in such a way that when it’s reached execution stops. Our research team has now devised a way of achieving this with PoET ticks.

The research team has finalized a number of other critical outstanding designs over the past few days. One of these is the design of the “precompiled” smart contracts that we’ll include at genesis—a single-sig and multi-sig wallet, and a vesting account for coins belonging to early contributors—as well as the plan by which these initial accounts will be deployed, and the transaction format necessary to support these account types and use cases. Another is the design of GenesisID, a feature that’s used to prevent cross-chain replay attacks and ensure that data originating from one network can never be broadcast successfully on another network. A third is the initial, genesis nonce scheme, which is similar to the “sequential integer”-type nonces employed by smart contract platforms like Ethereum, but allows gaps to accommodate the way the Spacemesh protocol orders transactions and selects blocks.

Finally, we’re very excited to share that we’ve finalized the details of the Spacemesh economic model, first announced late last year. The full specification, which accounts for every single smidge, is available in this repository, where you can also find a table with issuance details for the first ten years.

Community

The “Responsible Energy Use” social cause is still ongoing, with the Knowledge Expo and Earth Propaganda drop challenges finished, and a new drop challenge on its way.

It’s not just the Spacemesh team that’s international; our community is too. And to make sure our international spirit is flourishing everywhere, we’re looking to empower our global communities. We’re creating a mechanism on our community discord server for people to vote for the creation of new global communities, so that those who come together in Spacemesh can find solidarity in the language they’re most comfortable with.

Tomer Afek, our founder and CEO, wrote a message to our community, where he gives an overview of our progress, a preview of the road ahead to genesis, discusses our values and priorities, and dives into what we feel is the missing piece that we must bring into the world: the People’s Coin. More decentralized than any cryptocurrency that’s before.

Thank you all for taking this journey with us!


We’re halfway through 2022, and our outlook is optimistic. Though we’re still settling in with our newly-expanded team, we have momentum and we’re confident that genesis is coming soon.

One of the things at the forefront of our minds is governance and trust. As technologies become exponentially stronger, so does the need to guide and bind these technologies in an ethical way. This is what drives the need for sustainable, scalable, and decentralized base-layer technology that can be used by millions.

At Spacemesh, we view trust as a natural resource, and see trustless technologies as the drivers of bottom-up social change and creative destruction. But the process of creating that technology is not “trustless”. Our community has put their trust in us, and we don’t take that for granted. We are grateful for your engagement during this long wait; your creativity and enthusiasm inspire us to work even harder towards a better future.

Research & Development

On the protocol front, we finalized the design and began implementation work of the Hare certification round—the last major update to the Hare protocol for genesis. We’re also getting very close to finalizing several other important elements.

These include, firstly, the nonce scheme, which differs from the simple, sequential integer nonces that Ethereum uses, and better fits the mesh data structure. Secondly, the account data structures. Since we’re launching without light client support, we’ll be starting with a straightforward key-value database, but we need to factor in design considerations and do some future-proofing for upgrading to a trie structure later. And thirdly, the design for protocol versioning. This is an important tool to prevent cross-chain replay attacks, and to make sure that all relevant tooling (Smapp, explorer, dashboard, etc.) can support multiple chains at genesis.

Additionally, research efforts are underway regarding both SVM and the Accounts/Templates/Transactions model. The former involves discussions of the high-level tradeoffs among: account unification, consensus-execution decoupling (aka “miner-verifier separation”), semantic preprocessing of transactions, smart-contracts level metaprogramming (dynamic account creation, and dynamic template creation). The latter is well advanced, and will stand as a more formalized companion to the corresponding unified documentation chapters that we’ll begin publishing soon.

Regarding Smapp, we’ve entered the final testing phase of the latest Smapp release, which will include a new Modern Dark Skin and an updated meshing status screen that provides additional transparency regarding a smesher’s per-epoch eligibility and rewards. We began work on a Genesis Product Plan that includes upcoming updates and development of SMREPL, hardware wallet (Ledger) and Vault with MultiSig. We also started New API developments for Smeshing Statuses and Reward Estimation. This will expand into further API updates with the latest transaction format.


Community

The Responsible Energy Use social cause is underway.

After bringing the Digital Privacy cause to a close, our focus shifts to an issue that none of us can afford to ignore: our irresponsible use of energy. Despite many promising advancements in the technology surrounding greener and more sustainable energy production, “dirty” energy continues to account for just over half of all global carbon emissions, with those emissions increasing every year. With this cause, we hope to examine why this continues to be the case, and also discuss ways that we can help the transition to a more responsible mode of both using and producing energy.

Since this is such a huge and often intimidating topic, we kicked off the cause with the Knowledge Expo drop challenge, which invites our community to share videos, blog posts, and articles that they’ve found helpful or informative.

Our community also shared their knowledge in the last drop challenge of the “Digital Privacy” cause—Pro Tips—and we compiled their advice into a handy blog post. Our community continues to demonstrate what #winning_together is all about!

The first few months of 2022 have been a time of adjustment and adaptation for Team Spacemesh: in part because of world events, and in part because of major restructuring in the team. Making a layer-1 protocol is a challenge no matter how large or well-resourced the team, but even more so when the team and treasury are relatively small. There have been challenges in balancing testing (e.g., running a functional testnet) with ongoing dev work, and the pace of development has been slower than we'd like—-but we're confident that we now have the team and processes in place to address both of these issues.

Our new team members include the core developers Alexander Bergasov, Eugene Toropov, and Jonathan Zlotnik, infrastructure lead Andres Monje, app developer Max Parfenov, programmability lead Tannr Allard, and R&D coordinator Wojciech Klaudiusz Zaborowski.

We’ve also restructured management of our product and R&D teams, to make things more streamlined and structured. We can already feel how these efforts are paying off, though there’s still room to grow. In particular, we want to focus on promoting cross-team communication, transparency, and picking up the pace of development.

Recent developments have shown just how important it is to have layer-1 projects that are not based on Proof of Stake, and we’re anxious to meet that need. Communication and self-reflection are the keys to rising to the challenges awaiting us.


Development

As a team, we’re laser-focused on genesis.

Protocol-wise, we finalized and implemented accounts state management for genesis, made significant progress on the implementation of the account abstraction, switched to ECVRF-EDWARDS25519-SHA512-ELL2 as a vrf function across the whole protocol (proposals, hare, beacon), and implemented mempool management with conservative cache/state.

We’ve also been focusing in on the hare protocol by building an overview of the hare components that need attention, so that we can close the gap between research and implementation. This is because we need the hare protocol implementation to be rock-solid prior to genesis. This involves making the code very readable and maintainable so that, ideally, any researcher should be able to look at our implementation and quickly understand what’s different about this flavor of byzantine agreement.

Our documentation is getting similar attention. Spacemesh has reached a point in its maturity as a project that we feel ready to consolidate our documents with open source readiness in mind. To this end, we’ve also started a schema language draft—or “quipu”—to help with the specification of binary structures across the protocol.

On the Smapp front, there are several persistent bugs which have been negatively impacting user experience, and we’re working on addressing them all. But we’re doing a lot more than that: we realize that, to live up to our promise of being the crypto platform for everyone, we have to focus on making Smapp as intuitive and user-friendly as possible. As such, we’re refactoring the code to make Smapp faster and more responsive.

This is going to be quite the undertaking, since some parts of Smapp are still running on legacy architecture, and we expect there to be some regressions and bugs as a result. We encourage community members who notice anything amiss to report their findings on github or the #smapp channel on discord.


Research

We’ve started PoET benchmarking and tick implementation planning. ”PoET ticks” are how we intend to measure how long the PoET has worked for ATX weight purposes. Today we ignore this measure and always multiply the PoST value by 1. This is just a temporary implementation for testing, though, and we must start actually taking the amount of PoET work into account before genesis.

The way we do this will impact many parts of the system. If we use very high values for PoET, for example, we risk overflowing variables (e.g. when we multiply by very large PoST values and aggregate the entire weight of the epoch). So we must ensure that the numbers fit, or else use a different kind of variable entirely. This is where the benchmarks come in: we run them on different machines so that we know the scale of the number of PoET iterations that are possible in a 2-week epoch. (Epochs after genesis will last for 2 weeks.)

We’re also investigating eligibility magnitude estimation. This wasn’t part of our original plan, but it came up as an issue regarding what happens if industrial smeshers allocate huge amounts of storage to the system and how this would impact home smeshers. Making sure that our network can scale without jeopardizing the profitability and sustainability of home miners is a huge priority for us.


Community

The Spacemesh Social Causes Program is going strong. We’ve been tackling the “Digital Privacy” cause, because this is a big part of what Web3 is all about. Our most recent drop challenge, “Pro Tips”, really shows the power of people wanting to help each other out on the internet. This is what “winning together” is all about!

As the “Digital Privacy” cause winds down, we also have some thoughts about privacy more broadly. About why it’s always being undermined, and why it’s so important to protect it at all costs.

Of course, we can’t possibly win anything together without the help of our community. In May, we compiled and addressed community suggestions which had been shared with us on our discord server. While we can’t implement every suggestion, we’re deeply grateful for every single one of them. Not just because they often have good ideas and valuable insights, but because they show us that our community is invested in making Spacemesh succeed.

The “Same Opportunity” Social Cause went out with a bang! Together, our community created a fundraiser for the Peruvian NGO Agape Hand. The fundraising effort was brought to a close with two major events: the Agape Hand Raffle and the sale of Spacemesh’s first-ever NFT. This NFT was created by artist David Crunelle in collaboration with the Spacemesh community. It was sold for 5 ETH. In total, over $24000 was raised to help needy kids in Peru.

We learned a lot from this first social cause, and Alon Askal wrote a blog post to cap it off, reflecting on these lessons.

We’re now focusing on another social cause that is near and dear to our hearts: “Fight Censorship”.

Spacemesh 2021 End-of-Year Update

2021 has, in many ways, felt like a continuation of 2020. Institutions, particularly of the economic and monetary variety, continued to come under great stress. All across the world, we saw massive supply chain disruptions, along with a protest movement of voluntary unemployment, and high inflation rates that many economists were convinced couldn’t possibly happen.

In short, this year has only strengthened our conviction that we MUST have an alternative to the current global economic system: one which is robust, decentralized, and anti-fragile. Spacemesh is in a unique position to help usher in this kind of system, because it is both race-free and has a low barrier to entry–ensuring that miners without tons of resources can still reap the benefits of joining the network.

2021 was all about Spacemesh 0.2, and we did it! We added many new team members from all across the globe, including developers, researchers, and community facilitators. We have maintained our status working fully remote, with team members in the United States, Israel, Russia, Italy, Ukraine, Germany, India, and Taiwan.

As we move into 2022, we have Genesis squarely in our sights.

The full end-of-year update is available here.

go-spacemesh

It was another fantastically productive period for go-spacemesh development. In parallel to rolling out the new devnet, we’ve continued to identify and fix dozens of small and medium-sized issues and make numerous improvements to components including sync, peer accounting, Tortoise beacon, memory management, API, p2p networking, state management, metrics, and database.

Finished proof of concept for proposed libp2p integration.

Smapp

We are still working on getting Smapp 0.2 code complete and will release it to devnets and testnets as soon as it is ready.

Research

Continuing to work on finalizing the research roadmap for the next major milestone (0.3). This includes finalizing things like transaction selection, rewards, and account abstraction.

Spacemesh 0.2 Open Testnet - Tweedledum

We plan to launch Tweedledum as soon as Spacemesh 0.2 is a bit more stable and Smapp 0.2 is ready.

go-spacemesh

We’ve continued to make good progress on fixing issues including memory leaks and making under the hood improvements to core components such as sync, mesh, P2P, tortoise beacon, API, and database.

We successfully merged self-healing, the final big component to be included in the 0.2 milestone. This is exciting because it means that future devnets and testnets should be far more stable and more resilient to various issues.

We’re investing a lot of time and energy in making our build and testing environment (CI/CD) stabler and improving our testing infrastructure. We have a couple of team members dedicated to this task, but we’re looking to hire another. If you’re interested or know someone that might be, please check the posting on our website.

go-spacemesh

We merged several major improvements to the new Tortoise Beacon, and added support for the weak coin

We fixed several race conditions and memory leaks, which should make the 0.2 network much more stable

We merged several big improvements to the sync code, improved logging, and improved how nodes negotiate time

We began some groundwork to improve encoding and significantly reduce memory consumption as a result

We finished self-healing, another major part of the Tweedledum (0.2) milestone and cut the first 0.2 release candidate build. We launched a new internal devnet using this build.

Research

The research team remains focused on finalizing our mechanism designs for transaction selection and rewards for the 0.3 milestone.

Research is also actively contributing to SVM design and implementation, in particular, account state/trie design, account unification, and our nonce scheme.

SVM

We are making great progress with Global State porting, adding all necessary features for 0.3. We have plans for future modifications that will allow light clients support.

We implemented the verify step for the Accounts Unification.

We added a String type to the SDK (compliant with the Fixed-Gas constraints).

We added a Receipts Encoding SMIP.

Spacemesh Open Testnet - Tweedledee (Net 135)

After much deliberation, we’ve decided the time has come to retire Tweedledee. As such, testnet 135 has been taken down.

We’ll be transitioning the testnet infrastructure to run the brand new 0.2 code over the coming weeks. We hope to introduce a new, next-generation Tweedledum testnet in the coming weeks, and we appreciate your patience as we complete the transition.

go-spacemesh

A new dev workflow, focused on shorter sprints and more granular tasks, has allowed us to keep up the blistering pace of development on go-spacemesh. We merged roughly the same number of commits in the second half of July as we did during the first half of the month.

With the completion of the new GPU PoST code, we finished the 0.2 milestone. We are now one milestone away from our first mainnet release candidate.

We are testing the 0.2 code in an internal devnet, and will launch it on a public testnet as soon as it’s stable.

We’ve made several big improvements to sync, introduced safe layer math, fixed a memory leak in P2P, and streamlined how blocks are read from the database. As usual we’ve also made a slew of improvements to tooling, infrastructure, and testing.

Research

We remain focused on finalizing the designs for transaction selection and rewards, and moving these into development for the 0.3 milestone.

We are also improving the design of the sync algorithm to make sync as efficient and safe as possible, including looking at Graphene for set reconciliation.

Spacemesh relies far more heavily upon nodes being in agreement about time than do proof of work blockchains. We currently rely upon node operators synchronizing their node clocks using NTP, but we’ve begun to explore other possibilities, including baking a time sync mechanism into the Spacemesh protocol.

SVM

Efforts are largely focused on porting the Global-State to SVM. We are borrowing a lot from Alexey Akhunov’s work on Turbo-Geth and his innovative ideas, which will help us achieve good SVM throughput.

Main PRs:
Transaction `Envelope` and `Context`
Craft Deploy transactions from the CLI

go-spacemesh

It’s been an extraordinarily busy and productive couple of weeks for our dev team. We merged 23 commits to go-spacemesh alone. The pace of development has picked up as we’ve welcomed several new team members, are putting the finishing touches on the 0.2 release milestone, and are beginning to work on 0.3.

Major recent changes include a rewrite of the node syncer, upgrades to the Hare mechanism, introduction of the Tortoise Beacon (a major component of 0.2), and a slew of fixes and improvements for P2P, database, ATX/Nipst handling, data structures, and tooling.

We found a major issue (related to how we calculate the size of the active set) on the most recent testnet (the problem killed at least one previous testnet, and possibly several). We patched it on the testnet and we’re working on a longer-term fix for 0.2.

Research

We’re focused on finalizing the designs for account unification, including how to generalize nonces, transaction selection, and rewards.

Spacemesh Dev

Initial dev work on initial version go-ledger-sdk is complete and waiting to be merged. This library is designed to deliver support to the Spacemesh Ledger App to golang clients such as smrepl.

We found and fixed a memory leak in Tortoise, and fixed some low level networking issues as part of ongoing testnet work.

Research

We have a new SMIP on Account Unification, our candidate account model. It’s based on the Account Abstraction design from Ethereum, with modifications to support the mesh data structure.

We’re working on a “unified block” design that overcomes many of the challenges associated with the coordination problem of transaction selection in a mesh. It adds a step to the existing consensus process whereby participating nodes agree on not just a set of blocks and transactions to include in each layer, but also, how to order and aggregate those transactions into a single “superblock” per layer.

As part of the ongoing effort to investigate and respond to testnet issues, we’ve made great progress fixing issues that have arisen in the P2P (networking) stack, the Hare consensus mechanism, and elsewhere. Users should start to see the impact in terms of better UX starting with the next testnet.

We’ve added a new, more sophisticated type of logging, contextual logging, that adds a great deal of context to our logs and allows us to trace the path of an individual message or piece of data up and down the stack. This has already greatly facilitated debugging of the most complex issues (including the ones described in the previous bullet point).

Research

We’re finalizing the design of our account and transaction model. We’re researching the work that Ethereum and other communities have done on account abstraction (unifying multiple account and transaction types into a single model) and evaluating its suitability for Spacemesh.

While the Spacemesh topology makes it harder to calculate and compare a single state root per layer (relative to a chain topography), we’re researching ways to do just this to immediately detect bugs that lead to state forks.

We’ve made good progress on economic research, including an analysis of Filecoin economics and issuance model and its applicability to Spacemesh. We’ll announce a candidate economic and issuance plan soon.

Research continues on an efficient algorithm for transaction selection, which is an especially difficult problem in Spacemesh due to the fact that it’s a distributed knapsack problem.

We’ve put a lot of thought into streamlining our R&D pipeline to remove obstacles and ensure that we’re on the shortest possible path to genesis. We set up a new project board that can be used to track the pipeline.

We’re looking for strong go-developers to join our global core dev team

Research

We decided to drop BLS signatures in favor of ED25519, for reasons of efficiency. We’re also working on using a single pubkey for both VRF and NodeID signing.

We finalized our design for transaction signing, with future-proof support for pruning redundant transaction data later. This will allow us to move ahead with hardware wallet support.

We decided to support both standard ED25519 (which does not support pubkey extraction) and our ED25519++ design (which does) in the node, although only standard ED25519 transactions will be supported in Smapp at genesis. The former will result in larger, slightly more expensive transactions, while transactions using the latter will be slightly cheaper as they do not need to explicitly include the sender pubkey.

We’re finalizing our design for a NetworkID (unchanging post-genesis) and a ProtocolID (changes with every protocol update) for cross-network replay protection

We’re exploring a simpler, stateless multisig design and considering including multisig as a “first class” transaction type

Transaction selection is much trickier in the mesh topology than in a chain since, rather than a single miner constructing a single block, there are many smeshers and many blocks per layer, hence it’s a distributed knapsack problem. We’re evaluating a promising new proposal that cleverly avoids many of the challenges we face around transaction selection and ordering.

SVM

Spacemesh App

We are working on the following major updates to the app: use only the new Spacemesh API, support the new 0.2 transaction format, and include many user interface improvements and additional new features such as vaults and a new new user experience flow.

Spacemesh Web Services

  • We finished implementing full automation for deployment web services to a Spacemesh network using github actions and we have deployed the services to the new TweedleDee 123 testnet as well as a testnet statuspage https://status.spacemesh.io

Spacemesh Open Testnet - Tweedledee

Over the weekend, open testnet 122 experienced an issue that caused layer verification to fail. We are investigating the issue and will launch an updated testnet as soon as we have verified a fix.

Join Team Spacemesh!

We are looking to extend our core dev team with a few exceptional people. All positions are fully remote, so anyone with the requisite skills and experience may apply.

We’re looking for experienced Go developers to join our core dev team.

We’re also looking for a Principal Software developer to analyze and improve the Spacemesh protocol and its implementation.

go-spacemesh

We remain very focused on implementing Spacemesh protocol features as defined in our SMIPs. We also finalized several new specs that are about to go to development.

We are working on making tests more robust and less flaky.

Added ataxid and smesher id to api bloc.

Research

We finished a series of SMIPs specifying the software and protocol update process: for go-spacemesh, the protocol, Smapp, and code signing.

Preliminary research on transaction structure and processing is finished and implementation work will begin shortly. Innovations in this design include multiple transaction types (including a “batch” transaction type), a new nonce scheme better suited to a mesh (than a blockchain), and transaction pruning. See SMIP-37 for more.

Similarly, preliminary research on incentive design and rewards is finished and implementation work will begin shortly. We’ve settled on a design based on EIP-1559 (which has very good game theoretic properties and has already been implemented in major blockchains including Celo, Filecoin, and NEAR) that’s modified to better suit our mesh topology. Innovations in this design include how to pick a base fee per layer, pooling of fees and rewards, and reward maturation. See SMIP-38 for more.

Research is ongoing into how to allow unnecessary data to be pruned from the mesh using a strategy called dangling pointers, and into how to design a separate role in the protocol for validators (as opposed to miners). More on these topics soon.

SVM

Smapp

We have implemented most screens related to variable gpu-generated proof of space in preparation for the API support needed to complete this new major feature.

We implemented many new screens and features as well as updates to existing features.

Dashboard and Explorer

We fixed many issues we discovered on the open testnet explorer, and we finalized the first alpha release of both explorer and dashboard for the testnet.

We are working on a supported deployment of dashboard and explore for upcoming Testnet releases. Both dash and explore will be launched with the upcoming open testnet release.

CLIWallet

We completed a major update to the wallet which includes many new features. The wallet now uses the new Spacemesh API, and is able to connect to a public API endpoint securely over the Internet.

We are working on supporting Smapp’s wallet file format and storing sensitive wallet info in a secure way on disk.

Spacemesh API

  • We added smesherId and atx to block data structure to improve the information displayed in a Spacemesh explorer.

  • We implemented a supported secure public API endpoint for Spacemesh testnets. it will be launched with the upcoming testnet release.

Tweedledee - Spacemesh Open Testnet

We successfully soft-launched Tweedledee - the first Spacemesh open testnet - on March 1st. Since launch, we had over 100 people join the testnet from all over the world - mostly via word-of-mouth - and the network grew to about 700 p2p nodes from the 300 internally-managed p2p nodes to bootstrap the mesh. It currently runs about 440 full p2p nodes.

We started getting great feedback from the community and we have been busy fixing bugs and improving the network for the next app and p2p node update. Shout out to all who gave us feedback - you know who you are! Thanks to your invaluable input, we’re aiming to release a new minor app version with bug fixes in about 2 weeks.

We improved both the Testnet Guide and the Testnet FAQ based on user feedback and common questions.

We onboarded devs who wanted to join the Testnet by building go-spacmesh and our CLIWallet directly from source code and improved the joining documentation. We started to launch proper releases of go-spacemesh and the Spacemesh app for the testnet view github releases.

We operated the manual testnet tap and got many testnet users some Smesh to start playing around with coin transactions before getting their first smeshing coin rewards.

We ran a survey of early testnet users and received valuable feedback which was largely positive. Although users acknowledged that it was a bit rough around the edges, they were pleasantly surprised by how smoothly it ran at such an early stage.

From ffnet to Tweedledee

We launched a small experimental testnet for friends & family on Feb 15th with a network of 325 full nodes, and have been running the network for the last 2 weeks.

It’s super exciting for team Spacemesh to onboard our first group of real users using their home PCs, see them Smeshing, transacting with each other, and getting Smesh from the testnet tap.

We got some great feedback on the initial release, and already improved the user experience of the Spacemesh app by eliminating some annoying network requirements via p2p improvements, giving users complete control over where to store their proof-of-space file, and providing more information for users about their Smesher status.

Here’s some of the feedback we got:

“This is the smoothest UX i've experienced on a super early testnet”

“The visual feedback of this build is 10x better than the last, doesn't make you feel like it's just stuck”

“Just sent some SMD to someone. It works!!!

“I got my first smeshing reward!”

>> Tweedledee is Coming!

We finished preparing for the launch of our open testnet on March 1st including a new landing page and our comprehensive testnet guide. We call this release Spacemesh 0.1 / Tweedledee.

We are launching Tweedledee to learn from real users in the real world and the initial testnet release is just a beginning. It is experimental, has lots of bugs, and has a sub-optimal user experience - but it’s just the first iteration on our vision of home mining for everybody!

Follow the white rabbit...

Developers: Don’t Trust - Verify!

We're pleased to announce that we've added support for building a Spacemesh full node (go-spacemesh) and a fully functional CLI wallet directly from source code, and that you can join the open testnet using these instead of using the Spacemesh app and its managed full node. See dev documentation.

We published our updated 2020 roadmap on our road to mainnet.

We are finalizing a CLI wallet so people will be able to build a full node and the wallet from source code and join the testnet without using our reference GUI app.

We finished implementing and benchmarking a GPU optimized proof-of-space library utilizing the new cross-platform Vulkan GPU compute framework as well as OpenCL and Cuda. The library now provides an optimized implementation for all popular PC GPUs such as Nvidia and AMD on Windows, OS X and Linux. This library is going to be used to setup proof of space time on home PCs without hogging the CPU.

Spacemesh

We are on track to release Spacemesh 0.1 open testnet on March 1st. To get notified about when you can join with your PC at home, sign up here. Track our progress here and here

We clarified and updated our platform roadmap for 2020.

We published the first part of our dev docs for the protocols. Additional protocol docs are in the works and will be published soon.

We have set up an additional lite closed testnet env for testing with 50 nodes on google cloud and we are running closed testnets on this new env. See:

We have completed a comprehensive testnet guide for the Spacemesh 0.1 release with updated system requirements, coin units and additional screen shots.

Community

Welcome to 2020! Headsup that we are switching to a bi-weekly (every 2 week) cadence for these updates.

Smesher

We've found the memory leak that's been holding us back a few weeks now and have written code to fix it. PR is under review.

We're now testing the transaction mechanism with stress and stability tests and also testing sync.

We are running iterative closed testnets of between 200-300 nodes (currently 300) as we stabilize.

Merged issues

App

The bottleneck of updating the wallet file with recent changes (txs and rewards as txs) was removed.

Update doesn’t depend on retrieving tx statuses frequency.

App starts node from binary and not from container, most of run parameters are still hardcoded and any change requires app repackaging.

Business logic of querying node for it’s status and other requests were moved to later stage in order to allow running the node binary first.

Working on semi-automatic node start through the app.

closed issues in smapp repo.

SVM

Finished the last big refactoring effort - now the code should look better (hygiene-wise).

Currently working mainly on the 'app template' feature. We’ll have something called an "app template" from which we’ll be able to spawn multiple instances (called apps). Each app will have its own storage. All apps will use the same code defined in the app template. The motivation is to encourage code reuse and save on-mesh storage. (since we share code)

Wow what a year it has been. From everyone over here at Spacemesh, we hope you have a wonderful holiday season and happy new year. Here is the end of year wrap up - a summary of everything we accomplished over the course of 2019. Here's to 2020!

Happy new year from the Spacemesh Team!

We held a product summit where we defined our goals for iterative testnets and the road to mainnet.

Tal Moran, Chief Scientist, and Lane Rettig, Spacemesh Engineer @ our product summit.

Smesher

We have been testing the nodes sync and transaction processing, investigating memory leaks as well.

Merged issues

App

App is getting TXs from node and updates statuses in the UI. Smeshing rewards are displayed as transactions too now.

We are also working on a more robust way to save wallet data to disk to prevent data loss.

Finished refactoring to speed up the app and changed addresses length to match node settings

Autoupdater for Windows in progress

closed issues in smapp repo.

SVM

Refactored the codebase to improve code hygiene.

Decoupling wasmer from SVM external interface. This will open the door to having go-svm relying only on the svm object file (which will use wasmer internally, but this fact should become obvious to the end-user consuming svm)

ED25519 Public Key Extraction Go Library

https://github.com/spacemeshos/ed25519

An open-source drop-in replacement to golang/crypto/ed25519 with additional functionality.

We have developed this for the Spacemesh protocol since we could not find a good open source alternative. We hope that the open source blockchain dev community will find these capabilities useful in other scenarios and platforms.

In the ed25519 signature scheme, in order to verify the validity of a given signature, the validator should posses the public key of the signer. It can be sent along with the message and its signature, which means that the overall data being sent includes 256 bits of the public key. Our function allows to extract the public key from the signature (and the message), thus the public key may not be sent, resulting in a smaller transferred data.

  • Core dev team go-spacemesh project updates:

    On-going dev work at full steam ahead on p2p and the consensus protocol

    Set requirements for the Transaction processor and Account DB - two components that are representing the node's internal view of the mesh

    Set requirements for the mesh sync protocol that will allow a node to get the current mesh state for which a consensus can be proved

    Fixed a bug in the connection cache where in case two node's tried to simultaneously connect to each other they ended up with both connections getting closed

    Fixed a bug in the secured session where due to the nature of the crypto package that we are using, the decryption of messages that got encrypted and sent on the wire in different order failed.

    Made the listening port configurable and allowing nodes to discover other node's listening port using dht's discovery protocol
