We all have rather a lot to be grateful for this vacation season, from the primary birthday of the beacon chain, to the profitable upgrades over the previous yr and the unbelievable progress throughout your entire Ethereum ecosystem.
As a extremely productive yr attracts to a detailed, there are a number of closing items to ship within the type of updates from many (15+!!) EF-supported groups which might be at all times working to enhance the community. And there is a lot of substantive materials right here, so take a while to type via the desk of contents, and dig in!
As at all times, this roundup collection focuses on EF-supported groups whose members are working to develop and enhance Ethereum as a complete. Included on this version are updates from many groups highlighted in the earlier report, and different new and rotating teams.
Enjoy! 🦄
Consensus R&D (aka EF Research Team)
Authored by Hsiao-Wei Wang
In the second half of this yr, the milestones in Ethereum consensus R&D included:
To align with The Great Renaming, we shifted elements to “Consensus Layer” from “Eth2” for clearer communication in the long run.
In early 2022, our group will deal with serving to to ship the “The Merge”, probably the most vital consensus protocol improve ever. Fortunately, we now have nice assist from consumer groups, and others in the neighborhood working to make this a actuality! In the meantime, we will probably be persevering with our analysis work on knowledge availability, L1 scaling, and the options of the “clean up” fork after The Merge.
Ecosystem Support Program
Authored by ESP Team
We printed our Q2 Allocation Update with grants totalling $7,794,000 for the quarter – and Q3 is coming quickly! You also can take a look at current month-to-month roundups right here and right here for extra detailed progress updates from a number of of our fabulous grantees.
Behind the scenes, we’re engaged on a significant web site overhaul which ought to make it simpler than ever to know ESP’s mission and priorities, and for eligible builders to use for funding or different assist. We can’t wait to launch the brand new web site in early 2022!
Ethereum.org
Authored by Sam Richards
To make our work extra accessible and to foster extra neighborhood collaboration, our group publishes an summary of our quarterly roadmap targets. See our This autumn product roadmap right here.
Happy holidays to all from the ethereum.org group 😀🎄 As at all times, our imaginative and prescient with ethereum.org is to create the very best portal for Ethereum’s rising neighborhood and to function the entrance door to Ethereum for thousands and thousands of recent guests every month.
Content updates
Ethereum strikes quick! As effectively as updating a whole bunch of pages to make sure our content material stays updated and correct, we’ve additionally launched a bunch of recent content material:
Ethereum.org exists due to a whole bunch of content material and code contributors from the neighborhood. In Q3/This autumn, we put emphasis on methods to extend contributions and acknowledge the neighborhood for the work they have been doing:
Some stats (Aug – Dec)
- Our GitHub contributors elevated by 57%, from 396 to 621 😲
- Our Discord neighborhood practically doubled, from 6,500 to 12,200 members 🎉
- We’ve hosted two neighborhood calls and began office-hours for contributors
- We added 3 new neighborhood guides (trusted members answering questions and moderating chat) 😎
- We launched tiered POAPs to gamify contributions for content material, code, and translations
Translation Program
Since hiring our new Translation Lead in July, the Translation Program has actually ramped up!
Some stats:
- Between July and November, the neighborhood collectively translated 1,373,046 phrases for ethereum.org, over 10x the quantity of this identical interval final yr! To put this in perspective, that is equal to translating the whole lot of virtually 20 books 📚!
- We’ve acquired translation assist from over 2,500 neighborhood contributors 🤯
- We have 37 languages reside on ethereum.org 🌍
- We launched an initiative to higher acknowledge our translators, together with a leaderboard and translator certificates!
CLR funding
We’re supporting a clr.fund spherical on Layer 2! After over 6 months of contributing to clr.fund’s quadratic funding stack, we have merged our modifications to the upstream repo, which provides L2 community assist and a wide range of internet app enhancements.
clr.fund plans to deploy a funding spherical on Arbitrum One geared in the direction of the staking ecosystem in January, and the EF is happy to supply matching funds to the spherical. We hope you take part! Stay tuned for particulars. Yay public items!
We’ve been constructing on the shoulders of giants. Thank you to the clr.fund group, the MACI group & clr.fund’s neighborhood of contributors who proceed to push improvements within the ZKP & quadratic funding area.
What’s subsequent?
- making a studying hub to permit non-technical customers to grow to be proficient Ethereum customers
- constructing extra assets on operating nodes and staking to enhance accessibility
- additional automating our translation pipeline to launch translated content material out quicker
- increasing the Translation Program past ethereum.org
- updating content material to transition away from the Eth2 terminology because the merge approaches
How does that sound?
We admire suggestions on our roadmap. Our guiding rules are primarily based on delivering probably the most worth within the shortest time, so if there’s one thing you assume we should always work on, please tell us! We welcome concepts and contributions from anybody in the neighborhood.

Ipsilon
Authored by Alex Beregszaszi
We have created a group web site to offer a transparent explainer and to comprehensively record our present and previous work.
It is simple to inform from the next headers that within the second half of the yr the group principally targeted on the EVM. It’s additionally vital to say that we now have teamed up with the Geth Team to enhance the efficiency of the EVM interpreter.
EVM Object Format (EOF)
The first step in the direction of this, EIP-3541, went reside with London and we now have carried out a survey throughout many testnets and EVM chains to discover a becoming prefix for EOF.
Continued clarifications have been made to EIP-3540 (together with the chosen prefix), and we additionally proposed additional work constructing on prime of it:
- EIP-3670 to introduce code validation at deploy time
- EIP-3690 to exchange JUMPDEST opcodes with a JUMPDEST-table
- EIP-4200 to introduce two new opcodes, RJUMP and RJUMPI, facilitating static jumps
During October we introduced EOF at Liscon (slides right here, however the recording will not be obtainable) and on the Ethereum Meetup in Berlin (slides, recording).
Other EIPs
EIP-2681 (Limit account nonce to 2^64-1)
One of our outdated proposals, EIP-2681, was accepted throughout ACD#120. It codifies a restriction, which was already (partially) applied in apply in most shoppers. After acceptance we now have prolonged the Ethereum State Tests suite and adjusted the geth implementation.
EIP-3855 (PUSH0 instruction)
EIP-3855 proposes to introduce a PUSH0 instruction which pushes 0 onto the stack. This is a steadily used function, principally completed at present by way of inefficient or repurposed directions.
Our evaluation discovered that substantial assets may have been saved with this opcode:
To put the “waste” into perspective, throughout current accounts 340,557,331 bytes are wasted on PUSH1 00 directions, which implies 68,111,466,200 gasoline was spent to deploy them.
EIP-3860 (Limit and meter initcode)
EIP-3860 is a proposal to set a boundary and introduce metering for initcode. This would enable for extra optimised evaluation and execution, as a result of implementations would wish to cope with much less unknowns.
geth
As a collaboration with the Geth Team, we began to work on measuring and bettering the efficiency of the EVM interpreter in geth.
On the evaluation aspect two stories are noteworthy:
- Geth vs evmone compares the pace of Geth and evmone utilizing the benchmarking suite in evmone.
- Geth & Go compiler explores the impact of the Go compiler model on the pace of geth.
Based on these preliminary outcomes, we now have appeared into profiling geth, and eventually contributing a number of enhancements to the codebase, most of which has been already merged. A non-comprehensive record of related PRs: 23952, 23970, 23974, 23977, 24017, 24026, 24031, 24120.
Follow this hyperlink to see each PR. We plan to proceed this work within the subsequent quarter.
evmone
Two bugfix releases of evmone have been made: 0.8.1 and 0.8.2.
ethash
The group additionally maintains a C++ ethash/keccak256 library, which is utilized by evmone and Silkworm.
The newest 0.8.0 launch introduces a brand new technique for verifying the ultimate Ethash hashes towards the block issue. This is each a usability and pace enchancment. The technique has been posted on Ethresear.ch.
Additionally, ProgPoW has been deprecated within the library.
Fizzy
The group additionally participated within the Wasm in Web3 convention throughout September. We gave two displays:
- Fizzy — A deterministic interpreter (slides) gave a complete overview of what Fizzy is, the way it compares to different engines, and in addition explains the reasoning behind lots of the design decisions we made.
- Weird quirks whereas testing WebAssembly exhibits a wide variety of edge instances we now have encountered whereas creating Fizzy. The speak additionally provides some potential options and explainers for these edge instances, in addition to how we now have prolonged the official WebAssembly take a look at suite to cowl them.
Formal Verification
Authored by Leo Alt
In the second half of the yr the FV group continued to deal with our current instruments:
Act:
- We lastly launched Act 0.1! You can learn the superb tutorial at https://fv.ethereum.org/2021/08/31/act-0.1/ to verify what’s potential presently and methods to use it.
- We’re presently refactoring error dealing with to enhance usability.
Hevm:
SMTChecker:
- Track the balances of contracts exactly, together with msg.worth despatched to and from the analyzed contracts.
- Also assist the low-level name perform as an unsafe exterior name.
- Improve counterexamples by reporting block.*, msg.* and tx.* values which might be vital for failed verification targets.
- Report contract and reentrancy inductive invariants again to the consumer.
Geth
Authored by Felix Lange
In the second half of 2021, we printed 9 geth releases. As common, our time has been break up between EIP overview/implementation, consumer optimization/upkeep and reviewing code modifications proposed by the neighborhood.
In July, the London exhausting fork, which included EIP-1559, was activated. The new gasoline pricing scheme outlined by this EIP required many modifications throughout all subsystems of geth. We are nonetheless discovering and fixing corner-case points associated to EIP-1559 now, six months after its introduction.
Two safety vulnerabilities have been found prior to now six months. For each of them, we adopted our safety advisory coverage: we instantly assigned a CVE quantity to the difficulty and printed a hotfix launch. Technical particulars concerning the vulnerability have been printed 6-8 weeks later.
In the final quarter of 2021, our work has principally shifted in the direction of implementation and testing of The Merge. We are on observe to show geth into the ‘execution layer consumer’ of the merged execution+consensus (fmr. “eth1+eth2”) layers. In preparation for The Merge, we now have re-written a lot of the sync code to function underneath management of the consensus layer. Geth additionally participates in Merge testnets.
Additionally, the geth group has been engaged on a number of long-term tasks, corresponding to implementation of Verkle Trees, a beacon chain gentle consumer, and a brand new database storage scheme for the Ethereum state.
Javascript Team
Authored by Holger Drewes
In the final two quarters of 2021, preparations for “the big transitions” on the Ethereum community was a powerful focus of our work. We participated within the Merge Interop in Greece and launched the primary Merge-testnet prepared variations of our consumer, VM and associated libraries (see e.g. the EthereumJS consumer v0.2 launch). We additionally began on an thrilling experiment with the Go-Ethereum Verkle/Stateless group to natively take a look at stateless block execution primarily based on a verkle proof served alongside a modified block header by way of devp2p inside our consumer. If you have an interest you possibly can see the next monitoring difficulty to look at our progress.
A bit extra relevant for the top consumer proper now: the assist of our libraries for the rising L2 networks like Polygon, Arbitrum or Optimism has been improved. These and another networks can now straight be referenced to e.g. ship a transaction to a sure L2 community. See e.g. the Common v2.6.0 launch for the most recent Optimism L2 community integration.
And final however not least: there’s a VM ArrowGlacier launch obtainable and on the Ethers.js entrance. Richard has simply posted an thrilling overview on the upcoming Ethers.js v6 library modifications and updates on his weblog.
Privacy & Scaling Explorations
Authored by Thore Hildebrandt
The Privacy & Scaling Explorations group works to bridge the hole between cutting-edge analysis in zero-knowledge proofs, and utility improvement on Ethereum.
zkEVM
The objective of zkEVM is to run good contracts in a zk-rollup. Unfortunately, the EVM was not designed to run in a zk circuit which makes it a problem. We wish to implement the complete set of EVM opcodes straight into the zk circuits so a wise contract operating on L1 will be deployed to L2 with minimal modifications. This will enable full compatibility with current tooling and allow us to leverage information of the EVM that the ecosystem has constructed up over the previous years. We are making good progress on specification of the opcodes and implementation of the circuits, and we now have early benchmarks and an vital objective going ahead to convey prover time down.
ZKOPRU
ZKOPRU (zk-optimistic-rollup) is a layer-2 scaling answer for personal transactions utilizing zk-SNARK and optimistic rollup. It helps personal transfers and personal atomic swaps inside the layer-2 community between ETH, ERC20 and ERC721. It additionally supplies immediate withdrawal with pay-in-advance options and compliance compatibility utilizing spending key and viewing keys. ZKOPRU has lately launched on testnet – go forward and test it out. We’re engaged on bettering sync-times and on a non-public change function.
Unirep & Unirep Social
UniRep is a non-public and non-repudiable fame system. Users can obtain constructive and detrimental fame from attesters, and voluntarily show that they’ve a minimum of a specific amount of fame with out revealing the precise quantity. Moreover, customers can not refuse to obtain fame from an attester. We are utilizing Unirep to construct Unirep Social: a Reddit-like platform that enables customers to privately accumulate karma. Building the Unirep Social web site was our focus prior to now months. Proofs in Unirep are actually listed in order that they are often referred many occasions and forestall one proof from being submitted twice. Unirep can now deal with an preliminary fame airdrop and consumer state transition airdrop. We are additionally bettering the effectivity in producing consumer state and Unirep state.
Basic capabilities, frontend design, frontend and backend of Unirep Social are full, and we’re planning a closed pre-alpha launch. Check out this blogpost if you wish to be taught extra.
CLR.fund for Everyone
The objective of the challenge is to make it simple for any neighborhood to run their very own CLR spherical with clr.fund. This challenge has been very busy. You can now deploy your personal quadratic funding utility with the clr.fund Deployer. Empower your neighborhood to decide on and fund its personal future, in a completely decentralized method. Check out our Subgraph and Documentation.
InterRep
Reputation is the important thing to belief. People spend years increase their fame on centralized social platforms, however they’ve to start out from nothing at any time when they begin utilizing a brand new app. InterRep goals to make fame moveable to develop the compounding advantages of trusted human interactions throughout the net. Check out this blogpost for the preliminary announcement and the repo. In the previous quarter we now have expanded the vary of social proof sources, to POAP and electronic mail and have curated teams: on-chain, and off-chain by way of a Telegram bot. We are doing a UI redesign, bettering interplay with consumer purposes and making ready for a reside launch.
Semaphore / ZK-Keeper
Semaphore is a zero-knowledge gadget which permits customers to show their membership of a set with out revealing their authentic identification. At the identical time, it permits customers to sign their endorsement of an arbitrary string. It is designed to be a easy and generic privateness layer for Ethereum dApps. Use instances embrace personal voting, whistleblowing, mixers, and nameless authentication. With ZK-Keeper we’re focussing on protecting Semaphore updated with the most recent zk instruments and integrating it with different tasks like InterRep. We have new libs for dealing with semaphore proofs and identities. Implementation is now finished on prime of Halo2 and we’re getting it prepared for use within the browser.
RLN
RLN (Rate Limiting Nullifier) is a assemble primarily based on zero-knowledge proofs that permits spam prevention for decentralized, nameless environments. In nameless environments, the identification of the entities is unknown. We have lately printed an explanatory weblog publish to get extra folks excited concerning the thought. We have completed analysis round “Feasibility analysis for ETH2 Validator privacy using RLN”. We’re engaged on productionalizing the “Private instant chat app using RLN and Interrep” challenge. We’re additionally serving to to combine the ZK-Keeper plugin into the RLN tasks.
Protocol Support
Authored by Tim Beiko
The Protocol Support (PS) group was shaped in 2021 to develop the variety of methods wherein the groups constructing or interacting with the Ethereum base layer are supported. The group’s essential focus is enabling core builders to ship community upgrades on Ethereum’s execution layer.
To this impact, Berlin, London and Arrow Glacier have been deployed this yr. Beyond these, PS spent vital efforts working in the direction of The Merge, first with Rayonism, then the Amphora workshop and now the Kintsugi Devnet!
This accelerating tempo and scope of change has required extra outreach to the Ethereum neighborhood, which led our group to prepare frequent Community Calls. During these, utility, infrastructure and tooling builders have been invited to debate methods to greatest assist protocol upgrades and supply a clean transition for his or her customers. Alongside these calls, the group has given a number of talks and printed a number of posts concerning the altering Ethereum roadmap, corresponding to this current all core devs replace, this piece in Bankless and this current publish on the Merge and the applying layer within the EF Blog.
Beyond protocol upgrades, the PS group has taken on two main initiatives to make sure shoppers groups are effectively supported. First, a Client Incentive Program was introduced to provide groups Ethereum-aligned long-term incentives. The program supplies consumer groups with a set of 144 validators that they have to run utilizing their software program. Assuming groups preserve assembly sure efficiency benchmarks on mainnet, these validators are regularly vested to the groups, that are free to both liquidate them or preserve them operating to gather rewards and charges. This program aligns groups with Ethereum, ensures they’re “dogfooding” their shoppers on mainnet, and that they preserve delivering performant software program.
Second, a Core Developer Apprenticeship Program was launched. This program supplied stipends and mentorship to self-directed people who needed to dive deep into protocol improvement. CDAP was launched as an experiment which proved to be extremely profitable! Two cohorts have been run, with over 25 contributors. Of these, a minimum of 5 are actually working full time within the ecosystem. These preliminary cohorts have taught us rather a lot about what was good and what may very well be improved with this system. Expect a revamped CDAP in 2022!
Lastly, the group experimented with offering infrastructure to the consumer groups and broader neighborhood. To that finish, crawler.ethereum.org was shipped and open-sourced. We hope that having a further crawler operating and obtainable for the neighborhood to enhance, modify or fork helps present higher views of the community’s topology.
Remix
Authored by Rob Stupay
Over the previous 6 months, the Remix group has unscrewed the again of our app to do some intensive rewiring. First amongst these modifications was continued work on shifting our code to React. We additionally expanded our attain by dialing in some efficient channels to new communities, and onboarding new customers with a primary product “tour” of our IDE. We’ve plugged in tasks into our “experience”, integrating Slither, and Hardhat, in addition to updating the Remix VSCode extension.
And, if that’s not sufficient, we jammed on some instruments for collaborative coding, bettering Decentralized GIT and integrating Github. Last however not least, we’ve up to date our current plugins. In brief, we’ve maxed it out to 11.
See extra particulars in our article.
Robust Incentives Group
Authored by Barnabe Monnot
The RIG (Robust Incentives Group) welcomed new group members and took part in lots of vital milestones for the Ethereum protocol. For a fast refresher on what the RIG is and what we care about, you possibly can take a look at Protocol cryptoeconomics with the RIG, introduced by Barnabé at EthCC in July.
On the Proof-of-Stake consensus aspect, Caspar, who joined us as full-time analysis scientist earlier this yr, discovered a problem with the present fork alternative, written up as Three assaults on Proof-of-Stake Ethereum. Fortunately, there’s a robust candidate repair that was lately merged within the consensus specs, after many productive discussions with Stanford’s Tse Lab, who co-authored the “Three attacks” paper. Caspar and others additionally proposed a special mitigation (“proposer view merge“), that’s nonetheless underneath analysis. Check out Caspar at Liscon presenting his outcomes!
Shyam, who joined us first as analysis intern final summer season and is now a analysis assistant on the RIG, launched a collection of notebooks exploring the beacon chain statistics from many distinctive angles, together with oceanic video games and inequality. Shyam has additionally been engaged on an extension to our Beacon runner PoS simulation engine that features reinforcement studying. Check out his speak at EDCON!
Block 12,965,000, August fifth, 12:33:42 PM UTC, was an vital date for us: the London exhausting fork activated, and with it, EIP-1559. Over the final yr, we have launched a collection of notebooks presenting numerous simulations of the brand new payment market mechanism, which set the stage for additional evaluation after launch. Barnabé reported some outcomes early after, and with co-authors (together with Shyam) wrote up a longer-form paper, Transaction Fees on a Honeymoon: Ethereum’s EIP-1559 One Month Later. The paper is motivated by the behaviour of the 1559 replace rule in the true world, and opens new analysis instructions for enhancements to the rule.
The RIG was additionally carefully working with the cadCAD Edu group in making ready an online masterclass in validator economics, supported by a completely extensible mannequin of Ethereum economics (in Python).
Snake Charmers [Python Ecosystem]
Authored by Keri Clowes
In the second half of 2021, the Snake Charmers group accomplished the modifications wanted throughout the ecosystem to assist the London exhausting fork. This concerned wide-ranging, basic modifications all through our stack, particularly in Py-EVM, Ethereum Tester, Web3.py, and eth-account. There have been additionally two bug bounties submitted for Py-EVM which were fastened. We’ve ramped up efforts to generate academic content material, and positioned a much bigger emphasis on developer relations. And as at all times, there may be ongoing neighborhood assist, difficulty triage, and bug squashing throughout our Python instruments.

Portal
Authored by Piper Merriam
This yr has been a giant yr for the Portal Network. We began this yr with an thought and solely a free plan for methods to construct a peer-to-peer community that might ship light-weight entry to the Ethereum protocol. We now have three unbiased groups and implementations and are effectively underway to launching the preliminary testnet which ought to evolve into a completely practical community by the top of 2022.
The EF Portal group has been working exhausting on Trin, a portal consumer written in Rust. The EF Javascript group has additionally been engaged on Ultralight, a portal consumer written in Typescript geared toward being runnable within the browser. The group from Status.im has additionally been engaged on Fluffy, a portal consumer supposed for integration with the Status ethereum consumer and pockets options.
During this yr we now have solved the beforehand unsolved drawback of methods to distribute the present Ethereum State in a fashion that’s conducive to environment friendly storage and retrieval. We established the Portal Wire Protocol, an extensible base protocol that’s the basis of all the networks making up the Portal Network. We additionally had the pleasure of working with a number of contributors of the Core Developer Apprenticeship Program who used the Portal Network tasks as a leaping off level for entering into Core Protocol improvement.
Security [Security / Consensus Tests]
Authored by Security (Security / Consensus Tests) Team
On the safety and testing aspect, plenty of consideration has been given to the London improve and the upcoming merge. We’ve made updates on tooling for take a look at authoring and continued to enhance the reference exams.

In the second half of this yr, we launched Solidity variations 0.8.8, 0.8.9, 0.8.10 and 0.8.11:
- Solidity 0.8.8 brings you consumer outlined worth varieties as a significant new function. It additionally improves overriding interface capabilities, studying from immutables, and extra.
- Solidity 0.8.9 is a pure bugfix launch and fixes two vital, however low severity, bugs:
- Solidity 0.8.10 accommodates exterior perform name optimizations, permits the brand new EVM code generator for pure Yul mode and may report contract invariants and reentrancy properties via the SMTChecker.
- Solidity 0.8.11 provides a primary implementation of a Language Server and permits a safer strategy to carry out ABI-encoding.
Moreover, a number of Solidity group members introduced at ETHGlobal’s Developer Tool Summit:
The Solidity documentation bought a number of upgrades, most notably, we…
- up to date the assets part with basic assets, Ethereum IDEs, editor integrations, Solidity instruments, Solidity parsers and grammars.
- added the performance to open code examples within the documentation straight in Remix.
Lastly, we launched our yearly Solidity Developer Survey. If you’re a Solidity developer, please take 10 minutes to share your suggestions and participate within the survey right here. The survey will probably be open till thirty first of December 2021.
Oh and we’re hiring! Have a take a look at our C++ Engineer Solidity opening.
