All of us have lots to be pleased 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 all the Ethereum ecosystem.
As a extremely productive yr attracts to a detailed, there are just a few remaining presents to ship within the type of updates from many (15+!!) EF-supported groups which are at all times working to enhance the community. And there is a lot of substantive materials right here, so take a while to kind by way of 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 an entire. Included on this version are updates from many groups highlighted in the previous report, and different new and rotating teams.
Get pleasure from! 🦄
Consensus R&D (aka EF Analysis Staff)
Authored by Hsiao-Wei Wang
Within 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 crew will give attention to serving to to ship the “The Merge”, probably the most vital consensus protocol improve ever. Happily, now we have nice assist from consumer groups, and others locally 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 Help Program
Authored by ESP Staff
We revealed our Q2 Allocation Update with grants totalling $7,794,000 for the quarter – and Q3 is coming quickly! You can even take a look at current month-to-month roundups here and here for extra detailed progress updates from just a few of our fabulous grantees.
Behind the scenes, we’re engaged on a serious web site overhaul which ought to make it simpler than ever to grasp ESP’s mission and priorities, and for eligible builders to use for funding or different assist. We will’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 crew publishes an outline of our quarterly roadmap targets. See our Q4 product roadmap here.
Joyful holidays to all from the ethereum.org crew 😀🎄 As at all times, our vision with ethereum.org is to create the very best portal for Ethereum’s rising neighborhood and to function the entrance door to Ethereum for tens of millions 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 neighborhood. In Q3/This autumn, we put emphasis on methods to extend contributions and acknowledge the neighborhood for the work they had been doing:
Some stats (Aug – Dec)
- Our GitHub contributors elevated by 57%, from 396 to 621 😲
- Our Discord community practically doubled, from 6,500 to 12,200 members 🎉
- We’ve hosted two community 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 really 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 similar interval final yr! To place this in perspective, that is equal to translating the whole lot of virtually 20 books 📚!
- We have obtained translation assist from over 2,500 neighborhood contributors 🤯
- We’ve 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 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 crew, the MACI crew & clr.fund’s neighborhood of contributors who proceed to push improvements within the ZKP & quadratic funding house.
What’s subsequent?
- making a studying hub to permit non-technical customers to turn into proficient Ethereum customers
- constructing further sources on working nodes and staking to enhance accessibility
- additional automating our translation pipeline to launch translated content material out sooner
- 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 recognize suggestions on our roadmap. Our guiding ideas are primarily based 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 locally.
Ipsilon
Authored by Alex Beregszaszi
We’ve created a team website to supply 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 crew principally targeted on the EVM. It’s additionally vital to say that now we have teamed up with the Geth Staff to enhance the efficiency of the EVM interpreter.
EVM Object Format (EOF)
Step one in direction of this, EIP-3541, went reside with London and now we have conducted 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 prime of it:
- EIP-3670 to introduce code validation at deploy time
- EIP-3690 to switch JUMPDEST opcodes with a JUMPDEST-table
- EIP-4200 to introduce two new opcodes, RJUMP and RJUMPI, facilitating static jumps
Throughout October we offered EOF at Liscon (slides here, however the recording shouldn’t be obtainable) and on the Ethereum Meetup in Berlin (slides, recording).
Different EIPs
EIP-2681 (Restrict account nonce to 2^64-1)
One among our outdated proposals, EIP-2681, was accepted throughout ACD#120. It codifies a restriction, which was already (partially) carried out in apply in most shoppers. After acceptance now we have prolonged the Ethereum State Assessments 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 can be a often used characteristic, principally completed immediately through inefficient or repurposed directions.
Our evaluation discovered that substantial sources might have been saved with this opcode:
To place the “waste” into perspective, throughout present accounts 340,557,331 bytes are wasted on PUSH1 00 directions, which implies 68,111,466,200 fuel 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 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 Staff, 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.
Primarily based on these preliminary outcomes, now we have seemed 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.
Observe this link to see each PR. We plan to proceed this work within the subsequent quarter.
evmone
Two bugfix releases of evmone had been made: 0.8.1 and 0.8.2.
ethash
The crew additionally maintains a C++ ethash/keccak256 library, which is utilized by evmone and Silkworm.
The most recent 0.8.0 release introduces a brand new methodology for verifying the ultimate Ethash hashes towards the block problem. That is each a usability and pace enchancment. The strategy has been posted on Ethresear.ch.
Moreover, ProgPoW has been deprecated within the library.
Fizzy
The crew 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.
- Weird quirks while testing WebAssembly exhibits a wide selection of edge circumstances now we have encountered whereas growing Fizzy. The discuss additionally provides some potential options and explainers for these edge circumstances, in addition to how now we have prolonged the official WebAssembly check suite to cowl them.
Formal Verification
Authored by Leo Alt
Within the second half of the yr the FV crew continued to give attention to our present instruments:
Act:
- We lastly launched Act 0.1! You possibly can learn the wonderful tutorial at https://fv.ethereum.org/2021/08/31/act-0.1/ to verify what’s potential at the moment and easy methods to use it.
- We’re at the moment refactoring error dealing with to enhance usability.
Hevm:
SMTChecker:
- Monitor the balances of contracts exactly, together with msg.worth despatched to and from the analyzed contracts.
- Additionally assist the low-level name perform as an unsafe exterior name.
- Enhance counterexamples by reporting block.*, msg.* and tx.* values which are vital for failed verification targets.
- Report contract and reentrancy inductive invariants again to the consumer.
Geth
Authored by Felix Lange
Within the second half of 2021, we revealed 9 geth releases. As common, our time has been break up between EIP evaluation/implementation, consumer optimization/upkeep and reviewing code modifications proposed by the neighborhood.
In July, the London laborious fork, which included EIP-1559, was activated. The brand new fuel 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 up to now six months. For each of them, we adopted our safety advisory coverage: we instantly assigned a CVE quantity to the difficulty and revealed a hotfix launch. Technical particulars concerning the vulnerability had been revealed 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 monitor to show geth into the ‘execution layer consumer’ of the merged execution+consensus (fmr. “eth1+eth2”) layers. In preparation for The Merge, now we have re-written a lot of the sync code to function underneath management of the consensus layer. Geth additionally participates in Merge testnets.
Moreover, the geth crew has been engaged on a number of long-term tasks, akin to implementation of Verkle Bushes, a beacon chain gentle consumer, and a brand new database storage scheme for the Ethereum state.
Javascript Staff
Authored by Holger Drewes
Within the final two quarters of 2021, preparations for “the large 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 crew to natively check stateless block execution primarily based on a verkle proof served alongside a modified block header through devp2p inside our consumer. In case you are you possibly can see the next tracking issue to observe our progress.
A bit extra relevant for the tip 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 immediately 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 available 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 blog.
Privateness & Scaling Explorations
Authored by Thore Hildebrandt
The Privateness & Scaling Explorations crew works to bridge the hole between cutting-edge analysis in zero-knowledge proofs, and utility growth on Ethereum.
zkEVM
The purpose 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 immediately into the zk circuits so a wise contract working on L1 will be deployed to L2 with minimal modifications. This can enable full compatibility with present 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 now we have early benchmarks and an vital purpose going ahead to deliver 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 non-public transfers and personal atomic swaps inside the layer-2 community between ETH, ERC20 and ERC721. It additionally offers on the spot withdrawal with pay-in-advance options and compliance compatibility utilizing spending key and viewing keys. ZKOPRU has recently launched on testnet – go forward and test it out. We’re engaged on enhancing sync-times and on a non-public change characteristic.
Unirep & Unirep Social
UniRep is a non-public and non-repudiable popularity system. Customers can obtain constructive and destructive popularity from attesters, and voluntarily show that they’ve not less than a certain quantity of popularity with out revealing the precise quantity. Furthermore, customers can not refuse to obtain popularity from an attester. We’re utilizing Unirep to construct Unirep Social: a Reddit-like platform that enables customers to privately accumulate karma. Constructing the Unirep Social web site was our focus up to now months. Proofs in Unirep at the moment are listed in order that they are often referred many instances and stop one proof from being submitted twice. Unirep can now deal with an preliminary popularity airdrop and consumer state transition airdrop. We’re additionally enhancing the effectivity in producing consumer state and Unirep state.
Primary capabilities, frontend design, frontend and backend of Unirep Social are full, and we’re planning a closed pre-alpha launch. Take a look at this blogpost if you wish to study extra.
CLR.fund for Everybody
The purpose of the venture is to make it simple for any neighborhood to run their very own CLR spherical with clr.fund. This venture has been very busy. Now you can 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. Take a look at our Subgraph and Documentation.
InterRep
Repute is the important thing to belief. Folks spend years increase their popularity on centralized social platforms, however they’ve to begin from nothing each time they begin utilizing a brand new app. InterRep goals to make popularity moveable to increase the compounding advantages of trusted human interactions throughout the online. Check out this blogpost for the preliminary announcement and the repo. Up to now quarter now we have expanded the vary of social proof sources, to POAP and electronic mail and have curated teams: on-chain, and off-chain through a Telegram bot. We’re doing a UI redesign, enhancing interplay with consumer purposes and getting 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 unique identification. 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 non-public voting, whistleblowing, mixers, and nameless authentication. With ZK-Keeper we’re focussing on conserving Semaphore updated with the newest zk instruments and integrating it with different tasks like InterRep. We’ve 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 (Charge Limiting Nullifier) is a assemble primarily based on zero-knowledge proofs that allows spam prevention for decentralized, nameless environments. In nameless environments, the identification of the entities is unknown. We’ve lately revealed an explanatory blog post to get extra folks excited concerning the concept. We’ve completed analysis round “Feasibility evaluation for ETH2 Validator privateness utilizing RLN”. We’re engaged on productionalizing the “Non-public on the spot chat app utilizing RLN and Interrep” venture. We’re additionally serving to to combine the ZK-Keeper plugin into the RLN tasks.
Protocol Help
Authored by Tim Beiko
The Protocol Help (PS) crew was fashioned in 2021 to develop the variety of methods by which the groups constructing or interacting with the Ethereum base layer are supported. The crew’s predominant 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 neighborhood, which led our crew to prepare frequent Neighborhood Calls. Throughout these, utility, infrastructure and tooling builders had been invited to debate easy methods to finest assist protocol upgrades and supply a easy transition for his or her customers. Alongside these calls, the crew has given a number of talks and revealed a number of posts concerning the altering Ethereum roadmap, akin to this recent all core devs update, this piece in Bankless and this recent post on the Merge and the application layer in the EF Blog.
Past protocol upgrades, the PS crew has taken on two main initiatives to make sure shoppers groups are nicely supported. First, a Client Incentive Program was introduced to present groups Ethereum-aligned long-term incentives. This system offers consumer groups with a set of 144 validators that they have to run utilizing their software program. Assuming groups hold assembly sure efficiency benchmarks on mainnet, these validators are progressively vested to the groups, that are free to both liquidate them or hold them working to gather rewards and charges. This program aligns groups with Ethereum, ensures they’re “dogfooding” their shoppers on mainnet, and that they hold 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 growth. CDAP was launched as an experiment which proved to be extremely profitable! Two cohorts had been run, with over 25 members. Of those, not less than 5 at the moment are working full time within the ecosystem. These preliminary cohorts have taught us lots about what was good and what could possibly be improved with this system. Anticipate a revamped CDAP in 2022!
Lastly, the crew 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 working 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 crew has unscrewed the again of our app to do some intensive rewiring. First amongst these modifications was continued work on transferring 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 “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 present plugins. Briefly, we’ve maxed it out to 11.
See more details in our article.
Strong Incentives Group
Authored by Barnabe Monnot
The RIG (Strong Incentives Group) welcomed new crew 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, offered 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 attacks on Proof-of-Stake Ethereum. Happily, there’s a robust candidate repair that was recently 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 unique mitigation (“proposer view merge“), that’s nonetheless underneath analysis. Take a look at Caspar at Liscon presenting his outcomes!
Shyam, who joined us first as analysis intern final summer time and is now a analysis assistant on the RIG, launched a series of notebooks exploring the beacon chain statistics from many distinctive angles, together with oceanic games and inequality. Shyam has additionally been engaged on an extension to our Beacon runner PoS simulation engine that features reinforcement studying. Take a look at his talk at EDCON!
Block 12,965,000, August fifth, 12:33:42 PM UTC, was an vital date for us: the London laborious fork activated, and with it, EIP-1559. Over the past yr, we have launched a collection of notebooks presenting various 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 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 actual world, and opens new analysis instructions for enhancements to the rule.
The RIG was additionally intently working with the cadCAD Edu crew in getting ready an online masterclass in validator economics, supported by a completely extensible model of Ethereum economics (in Python).
Snake Charmers [Python Ecosystem]
Authored by Keri Clowes
Within the second half of 2021, the Snake Charmers crew accomplished the modifications wanted throughout the ecosystem to assist the London laborious 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 have been mounted. We’ve ramped up efforts to generate instructional content material, and positioned an even bigger emphasis on developer relations. And as at all times, there’s ongoing neighborhood assist, challenge triage, and bug squashing throughout our Python instruments.

Portal
Authored by Piper Merriam
This yr has been an enormous yr for the Portal Network. We began this yr with an concept and solely a free plan for easy methods to 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 completely purposeful community by the tip of 2022.
The EF Portal crew has been working laborious on Trin, a portal consumer written in Rust. The EF Javascript crew has additionally been engaged on Ultralight, a portal consumer written in Typescript geared toward being runnable within the browser. The crew from Status.im has additionally been engaged on Fluffy, a portal consumer meant for integration with the Standing ethereum consumer and pockets options.
Throughout this yr now we have solved the beforehand unsolved drawback of easy 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 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 moving into Core Protocol growth.
Safety [Security / Consensus Tests]
Authored by Safety (Safety / Consensus Assessments) Staff
On the safety and testing aspect, a number of consideration has been given to the London improve and the upcoming merge. We’ve made updates on tooling for check authoring and continued to enhance the reference assessments.
