All of us have loads to be glad about this vacation season, from the primary birthday of the beacon chain, to the profitable upgrades over the previous yr and the unimaginable progress throughout the complete Ethereum ecosystem.
As a extremely productive yr attracts to an in depth, there are just a few ultimate presents to ship within the type of updates from many (15+!!) EF-supported groups which might be all the time working to enhance the community. And there is a lot of substantive materials right here, so take a while to type by means of the desk of contents, and dig in!
As all the time, this roundup collection focuses on EF-supported groups whose members are working to develop and enhance Ethereum as an entire. Included on this version are updates from many groups highlighted in the earlier report, and different new and rotating teams.
Take pleasure in! 🦄
Consensus R&D (aka EF Analysis Group)
Authored by Hsiao-Wei Wang
Within the second half of this yr, the milestones in Ethereum consensus R&D included:
To align with The Nice Renaming, we shifted parts to “Consensus Layer” from “Eth2” for clearer communication in the long run.
In early 2022, our workforce will give attention to serving to to ship the “The Merge”, probably the most vital consensus protocol improve ever. Luckily, we now have nice help from shopper groups, and others in the neighborhood working to make this a actuality! Within the meantime, we will probably be persevering with our analysis work on information availability, L1 scaling, and the options of the “clear up” fork after The Merge.
Ecosystem Assist Program
Authored by ESP Group
We printed our Q2 Allocation Replace with grants totalling $7,794,000 for the quarter – and Q3 is coming quickly! You can too take a look at current month-to-month roundups right here and right here for extra detailed progress updates from just a few 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 help. We are able to’t wait to launch the brand new web site in early 2022!

To make our work extra accessible and to foster extra group collaboration, our workforce publishes an outline of our quarterly roadmap targets. See our This fall product roadmap right here.
Completely satisfied holidays to all from the ethereum.org workforce 😀🎄 As all the time, our imaginative and prescient with ethereum.org is to create one of the best portal for Ethereum’s rising group and to function the entrance door to Ethereum for hundreds of thousands of recent guests every month.
Content material updates
Ethereum strikes quick! In addition to updating tons of 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 because of tons of of content material and code contributors from the group. In Q3/This fall, we put emphasis on methods to extend contributions and acknowledge the group for the work they had been doing:
Some stats (Aug – Dec)
- Our GitHub contributors elevated by 57%, from 396 to 621 😲
- Our Discord group practically doubled, from 6,500 to 12,200 members 🎉
- We’ve hosted two group calls and began office-hours for contributors
- We added 3 new group guides (trusted members answering questions and moderating chat) 😎
- We launched tiered POAPs to gamify contributions for content material, code, and translations
Since hiring our new Translation Lead in July, the Translation Program has actually ramped up!
- Between July and November, the group collectively translated 1,373,046 phrases for ethereum.org, over 10x the quantity of this similar interval final yr! To place this in perspective, that is equal to translating the whole thing of just about 20 books 📚!
- We have acquired translation help from over 2,500 group contributors 🤯
- We have now 37 languages dwell on ethereum.org 🌍
- We launched an initiative to higher acknowledge our translators, together with a leaderboard and translator certificates!
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 help and a wide range of net app enhancements.
clr.fund plans to deploy a funding spherical on Arbitrum One geared in direction of the staking ecosystem in January, and the EF is happy to supply matching funds to the spherical. We hope you take part! Keep tuned for particulars. Yay public items!
We have been constructing on the shoulders of giants. Thanks to the clr.fund workforce, the MACI workforce & clr.fund’s group of contributors who proceed to push improvements within the ZKP & quadratic funding house.
- making a studying hub to permit non-technical customers to turn out to be proficient Ethereum customers
- constructing extra sources 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 ideas are based mostly on delivering probably the most worth within the shortest time, so if there’s one thing you assume we must always work on, please tell us! We welcome concepts and contributions from anybody in the neighborhood.

We have now created a workforce web site to offer a transparent explainer and to comprehensively record our present and previous work.
It’s simple to inform from the next headers that within the second half of the yr the workforce principally targeted on the EVM. It’s additionally necessary to say that we now have teamed up with the Geth Group to enhance the efficiency of the EVM interpreter.
EVM Object Format (EOF)
Step one in direction of this, EIP-3541, went dwell 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 had been made to EIP-3540 (together with the chosen prefix), and we additionally proposed additional work constructing on high 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
Throughout October we introduced EOF at Liscon (slides right here, however the recording isn’t obtainable) and on the Ethereum Meetup in Berlin (slides, recording).
EIP-2681 (Restrict account nonce to 2^64-1)
One in every of our previous proposals, EIP-2681, was accepted throughout ACD#120. It codifies a restriction, which was already (partially) applied in follow in most purchasers. After acceptance we now have prolonged the Ethereum State Exams suite and adjusted the geth implementation.
EIP-3855 (PUSH0 instruction)
EIP-3855 proposes to introduce a PUSH0 instruction which pushes 0 onto the stack. It is a regularly used characteristic, principally completed at present through inefficient or repurposed directions.
Our evaluation discovered that substantial sources may have been saved with this opcode:
To place the “waste” into perspective, throughout current accounts 340,557,331 bytes are wasted on PUSH1 00 directions, which suggests 68,111,466,200 gasoline was spent to deploy them.
EIP-3860 (Restrict and meter initcode)
EIP-3860 is a proposal to set a boundary and introduce metering for initcode. This may permit for extra optimised evaluation and execution, as a result of implementations would wish to cope with much less unknowns.
As a collaboration with the Geth Group, we began to work on measuring and enhancing 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 mostly on these preliminary outcomes, we now have appeared into profiling geth, and at last 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.
Comply with this hyperlink to see each PR. We plan to proceed this work within the subsequent quarter.
Two bugfix releases of evmone had been made: 0.8.1 and 0.8.2.
The workforce additionally maintains a C++ ethash/keccak256 library, which is utilized by evmone and Silkworm.
The most recent 0.8.0 launch introduces a brand new methodology for verifying the ultimate Ethash hashes towards the block issue. That is each a usability and pace enchancment. The strategy has been posted on Ethresear.ch.
Moreover, ProgPoW has been deprecated within the library.
The workforce 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 most of the design decisions we made.
- Bizarre quirks whereas testing WebAssembly reveals a wide variety of edge circumstances we now have encountered whereas growing Fizzy. The discuss additionally provides some potential options and explainers for these edge circumstances, in addition to how we now have prolonged the official WebAssembly take a look at suite to cowl them.

Within the second half of the yr the FV workforce continued to give attention to our current instruments:
- We lastly launched Act 0.1! You possibly can learn the superb tutorial at https://fv.ethereum.org/2021/08/31/act-0.1/ to examine what’s doable at the moment and use it.
- We’re at the moment refactoring error dealing with to enhance usability.
- Monitor the balances of contracts exactly, together with msg.worth despatched to and from the analyzed contracts.
- Additionally help the low-level name operate as an unsafe exterior name.
- Enhance counterexamples by reporting block.*, msg.* and tx.* values which might be necessary for failed verification targets.
- Report contract and reentrancy inductive invariants again to the consumer.

Within the second half of 2021, we printed 9 geth releases. As common, our time has been break up between EIP overview/implementation, shopper optimization/upkeep and reviewing code modifications proposed by the group.
In July, the London exhausting fork, which included EIP-1559, was activated. The brand new gasoline pricing scheme outlined by this EIP required many modifications throughout all subsystems of geth. We’re nonetheless discovering and fixing corner-case points associated to EIP-1559 now, six months after its introduction.
Two safety vulnerabilities had been found previously six months. For each of them, we adopted our safety advisory coverage: we instantly assigned a CVE quantity to the problem and printed a hotfix launch. Technical particulars concerning the vulnerability had been printed 6-8 weeks later.
Within the final quarter of 2021, our work has principally shifted in direction of implementation and testing of The Merge. We’re on observe to show geth into the ‘execution layer shopper’ 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 below management of the consensus layer. Geth additionally participates in Merge testnets.
Moreover, the geth workforce has been engaged on a number of long-term tasks, resembling implementation of Verkle Timber, a beacon chain gentle shopper, and a brand new database storage scheme for the Ethereum state.

Within the final two quarters of 2021, preparations for “the large transitions” on the Ethereum community was a robust focus of our work. We participated within the Merge Interop in Greece and launched the primary Merge-testnet prepared variations of our shopper, VM and associated libraries (see e.g. the EthereumJS shopper v0.2 launch). We additionally began on an thrilling experiment with the Go-Ethereum Verkle/Stateless workforce to natively take a look at stateless block execution based mostly on a verkle proof served alongside a modified block header through devp2p inside our shopper. In case you are you possibly can see the next monitoring subject to look at our progress.
A bit extra relevant for the top consumer proper now: the help 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 Frequent v2.6.0 launch for the newest 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.
Privateness & Scaling Explorations
Authored by Thore Hildebrandt
The Privateness & Scaling Explorations workforce works to bridge the hole between cutting-edge analysis in zero-knowledge proofs, and software improvement on Ethereum.
The objective of zkEVM is to run sensible contracts in a zk-rollup. Sadly, the EVM was not designed to run in a zk circuit which makes it a problem. We need to implement the total set of EVM opcodes straight into the zk circuits so a wise contract operating on L1 could be deployed to L2 with minimal modifications. This can permit full compatibility with current tooling and allow us to leverage data of the EVM that the ecosystem has constructed up over the previous years. We’re making good progress on specification of the opcodes and implementation of the circuits, and we now have early benchmarks and an necessary objective going ahead to carry prover time down.
ZKOPRU (zk-optimistic-rollup) is a layer-2 scaling resolution for personal transactions utilizing zk-SNARK and optimistic rollup. It helps personal transfers and personal atomic swaps throughout 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 just lately launched on testnet – go forward and test it out. We’re engaged on enhancing sync-times and on a personal trade characteristic.
Unirep & Unirep Social
UniRep is a personal and non-repudiable repute system. Customers can obtain constructive and damaging repute from attesters, and voluntarily show that they’ve at the least a certain quantity of repute with out revealing the precise quantity. Furthermore, customers can’t refuse to obtain repute from an attester. We’re utilizing Unirep to construct Unirep Social: a Reddit-like platform that permits customers to privately accumulate karma. Constructing the Unirep Social web site was our focus previously months. Proofs in Unirep at the moment are 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 repute airdrop and consumer state transition airdrop. We’re additionally enhancing the effectivity in producing consumer state and Unirep state.
Fundamental features, frontend design, frontend and backend of Unirep Social are full, and we’re planning a closed pre-alpha launch. Try this blogpost if you wish to study extra.
CLR.fund for Everybody
The objective of the undertaking is to make it simple for any group to run their very own CLR spherical with clr.fund. This undertaking has been very busy. Now you can deploy your personal quadratic funding software with the clr.fund Deployer. Empower your group to decide on and fund its personal future, in a totally decentralized method. Try our Subgraph and Documentation.
Popularity is the important thing to belief. Individuals spend years build up their repute on centralized social platforms, however they’ve to start out from nothing each time they begin utilizing a brand new app. InterRep goals to make repute transportable to increase the compounding advantages of trusted human interactions throughout the net. Try this blogpost for the preliminary announcement and the repo. Up to now quarter we now have expanded the vary of social proof sources, to POAP and e-mail and have curated teams: on-chain, and off-chain through a Telegram bot. We’re doing a UI redesign, enhancing interplay with shopper functions and making ready for a dwell launch.
Semaphore / ZK-Keeper
Semaphore is a zero-knowledge gadget which permits customers to show their membership of a set with out revealing their unique id. On the similar time, it permits customers to sign their endorsement of an arbitrary string. It’s designed to be a easy and generic privateness layer for Ethereum dApps. Use circumstances embody personal voting, whistleblowing, mixers, and nameless authentication. With ZK-Keeper we’re focussing on holding Semaphore updated with the newest zk instruments and integrating it with different tasks like InterRep. We have now new libs for dealing with semaphore proofs and identities. Implementation is now performed on high of Halo2 and we’re getting it prepared for use within the browser.
RLN (Fee Limiting Nullifier) is a assemble based mostly on zero-knowledge proofs that allows spam prevention for decentralized, nameless environments. In nameless environments, the id of the entities is unknown. We have now just lately printed an explanatory weblog publish to get extra folks excited concerning the concept. We have now completed analysis round “Feasibility evaluation for ETH2 Validator privateness utilizing RLN”. We’re engaged on productionalizing the “Non-public immediate chat app utilizing RLN and Interrep” undertaking. We’re additionally serving to to combine the ZK-Keeper plugin into the RLN tasks.

The Protocol Assist (PS) workforce was shaped in 2021 to develop the variety of methods by which the groups constructing or interacting with the Ethereum base layer are supported. The workforce’s major focus is enabling core builders to ship community upgrades on Ethereum’s execution layer.
To this impact, Berlin, London and Arrow Glacier had been deployed this yr. Past these, PS spent vital efforts working in 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 group, which led our workforce to prepare frequent Neighborhood Calls. Throughout these, software, infrastructure and tooling builders had been invited to debate greatest help protocol upgrades and supply a easy transition for his or her customers. Alongside these calls, the workforce has given a number of talks and printed a number of posts concerning the altering Ethereum roadmap, resembling this current all core devs replace, this piece in Bankless and this current publish on the Merge and the applying layer within the EF Weblog.
Past protocol upgrades, the PS workforce has taken on two main initiatives to make sure purchasers groups are nicely supported. First, a Shopper Incentive Program was introduced to offer groups Ethereum-aligned long-term incentives. This system supplies shopper 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 progressively vested to the groups, that are free to both liquidate them or preserve them operating to gather rewards and costs. This program aligns groups with Ethereum, ensures they’re “dogfooding” their purchasers 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 had been run, with over 25 members. Of those, at the least 5 at the moment are working full time within the ecosystem. These preliminary cohorts have taught us loads about what was good and what may very well be improved with this system. Anticipate a revamped CDAP in 2022!
Lastly, the workforce experimented with offering infrastructure to the shopper groups and broader group. To that finish, crawler.ethereum.org was shipped and open-sourced. We hope that having an extra crawler operating and obtainable for the group to enhance, modify or fork helps present higher views of the community’s topology.

Over the previous 6 months, the Remix workforce has unscrewed the again of our app to do some in depth 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 fundamental product “tour” of our IDE. We’ve plugged in tasks into our “expertise”, 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, enhancing Decentralized GIT and integrating Github. Final however not least, we’ve up to date our current plugins. In brief, we’ve maxed it out to 11.

Strong Incentives Group
Authored by Barnabe Monnot
The RIG (Strong Incentives Group) welcomed new workforce members and took part in lots of necessary 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 difficulty with the present fork alternative, written up as Three assaults on Proof-of-Stake Ethereum. Luckily, there’s a sturdy candidate repair that was just lately merged within the consensus specs, after many productive discussions with Stanford’s Tse Lab, who co-authored the “Three assaults” paper. Caspar and others additionally proposed a distinct mitigation (“proposer view merge“), that’s nonetheless below analysis. Try 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. Try his discuss at EDCON!
Block 12,965,000, August fifth, 12:33:42 PM UTC, was an necessary date for us: the London exhausting fork activated, and with it, EIP-1559. During the last yr, we have launched a collection of notebooks presenting numerous simulations of the brand new charge 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 Charges 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 intently working with the cadCAD Edu workforce in making ready an internet masterclass in validator economics, supported by a totally extensible mannequin of Ethereum economics (in Python).
Snake Charmers [Python Ecosystem]
Authored by Keri Clowes
Within the second half of 2021, the Snake Charmers workforce accomplished the modifications wanted throughout the ecosystem to help the London exhausting fork. This concerned wide-ranging, elementary 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 instructional content material, and positioned an even bigger emphasis on developer relations. And as all the time, there may be ongoing group help, subject triage, and bug squashing throughout our Python instruments.

This yr has been an enormous yr for the Portal Community. We began this yr with an concept and solely a unfastened plan for construct a peer-to-peer community that might ship light-weight entry to the Ethereum protocol. We now have three impartial groups and implementations and are nicely underway to launching the preliminary testnet which ought to evolve into a totally purposeful community by the top of 2022.
Throughout this yr we now have solved the beforehand unsolved downside of 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 Community. We additionally had the pleasure of working with a number of members of the Core Developer Apprenticeship Program who used the Portal Community tasks as a leaping off level for stepping into Core Protocol improvement.
