All of us 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 all the Ethereum ecosystem.
As a extremely productive yr attracts to a detailed, there are just a few ultimate items to ship within the type of updates from many (15+!!) EF-supported groups which can 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 way of the desk of contents, and dig in!
As all the time, this roundup sequence 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.
Get pleasure from! 🦄
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 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”, essentially the most important consensus protocol improve ever. Thankfully, we’ve nice assist from shopper groups, and others locally working to make this a actuality! Within the meantime, we might 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 Group
We revealed our Q2 Allocation Replace with grants totalling $7,794,000 for the quarter – and Q3 is coming quickly! It’s also possible to take a look at latest 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 serious 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 are able to’t wait to launch the brand new website in early 2022!
Ethereum.org
Authored by Sam Richards
To make our work extra accessible and to foster extra group collaboration, our crew publishes an summary of our quarterly roadmap objectives. See our This autumn product roadmap right here.
Pleased holidays to all from the ethereum.org crew 😀🎄 As all the time, our imaginative and prescient with ethereum.org is to create the very best portal for Ethereum’s rising group 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 a whole lot 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 lot of content material and code contributors from the group. In Q3/This autumn, 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
Translation Program
Since hiring our new Translation Lead in July, the Translation Program has actually ramped up!
Some stats:
- Between July and November, the group collectively translated 1,373,046 phrases for ethereum.org, over 10x the quantity of this identical 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 assist from over 2,500 group contributors 🤯
- We’ve 37 languages stay on ethereum.org 🌍
- We launched an initiative to raised 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 worked up 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 group 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 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 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 respect suggestions on our roadmap. Our guiding rules are primarily based on delivering essentially the most worth within the shortest time, so if there’s one thing you suppose 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 crew web site to supply a transparent explainer and to comprehensively record our present and previous work.
It’s straightforward to inform from the next headers that within the second half of the yr the crew largely centered on the EVM. It’s additionally vital to say that we’ve teamed up with the Geth Group to enhance the efficiency of the EVM interpreter.
EVM Object Format (EOF)
Step one in the direction of this, EIP-3541, went stay with London and we’ve 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 interchange 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 will not be accessible) and on the Ethereum Meetup in Berlin (slides, recording).
Different EIPs
EIP-2681 (Restrict account nonce to 2^64-1)
One among 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’ve 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. It is a regularly used function, largely completed right this moment by way of 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 might 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 Group, we began to work on measuring and enhancing the efficiency of the EVM interpreter in geth.
On the evaluation facet two reviews 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’ve seemed 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.
Observe this hyperlink 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 newest 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.
Fizzy
The crew additionally participated within the Wasm in Web3 convention throughout September. We gave two shows:
- 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.
- Bizarre quirks whereas testing WebAssembly exhibits a wide variety of edge circumstances we’ve encountered whereas growing Fizzy. The discuss additionally provides some potential options and explainers for these edge circumstances, in addition to how we’ve prolonged the official WebAssembly take a look at 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’ll be able to learn the superb tutorial at https://fv.ethereum.org/2021/08/31/act-0.1/ to verify what’s doable presently and the right way to use it.
- We’re presently refactoring error dealing with to enhance usability.
Hevm:
SMTChecker:
- Observe the balances of contracts exactly, together with msg.worth despatched to and from the analyzed contracts.
- Additionally assist the low-level name operate as an unsafe exterior name.
- Enhance counterexamples by reporting block.*, msg.* and tx.* values which can be vital for failed verification targets.
- Report contract and reentrancy inductive invariants again to the person.
Geth
Authored by Felix Lange
Within the second half of 2021, we revealed 9 geth releases. As typical, our time has been cut up between EIP evaluate/implementation, shopper optimization/upkeep and reviewing code modifications proposed by the group.
In July, the London arduous 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 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 revealed a hotfix launch. Technical particulars in regards to the vulnerability had been revealed 6-8 weeks later.
Within the final quarter of 2021, our work has largely shifted in the direction of implementation and testing of The Merge. We’re on monitor to show geth into the ‘execution layer shopper’ of the merged execution+consensus (fmr. “eth1+eth2”) layers. In preparation for The Merge, we’ve 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 crew has been engaged on a number of long-term tasks, corresponding to implementation of Verkle Timber, a beacon chain mild shopper, and a brand new database storage scheme for the Ethereum state.
Javascript Group
Authored by Holger Drewes
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 crew 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 shopper. In case you are you may see the next monitoring problem to look at our progress.
A bit extra relevant for the tip person 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 Widespread v2.6.0 launch for the newest Optimism L2 community integration.
And final however not least: there’s a VM ArrowGlacier launch accessible 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 crew 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 sensible contracts in a zk-rollup. Sadly, 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 working on L1 could be deployed to L2 with minimal modifications. It will enable full compatibility with present tooling and allow us to leverage information 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’ve early benchmarks and an vital objective going ahead to convey prover time down.
ZKOPRU
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 inside the layer-2 community between ETH, ERC20 and ERC721. It additionally supplies on the spot 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 non-public change function.
Unirep & Unirep Social
UniRep is a non-public and non-repudiable fame system. Customers can obtain constructive and destructive fame from attesters, and voluntarily show that they’ve at the very least a specific amount of fame with out revealing the precise quantity. Furthermore, customers can not refuse to obtain fame 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 prior to now months. Proofs in Unirep at the moment are listed in order that they are often referred many instances and forestall one proof from being submitted twice. Unirep can now deal with an preliminary fame airdrop and person state transition airdrop. We’re additionally enhancing the effectivity in producing person 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. Try this blogpost if you wish to be taught extra.
CLR.fund for Everybody
The objective of the mission is to make it straightforward for any group to run their very own CLR spherical with clr.fund. This mission has been very busy. Now you can deploy your individual quadratic funding utility with the clr.fund Deployer. Empower your group to decide on and fund its personal future, in a completely decentralized method. Try our Subgraph and Documentation.
InterRep
Repute is the important thing to belief. Folks spend years build up 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 broaden the compounding advantages of trusted human interactions throughout the online. Try this blogpost for the preliminary announcement and the repo. Prior to now quarter we’ve expanded the vary of social proof sources, to POAP and e-mail and have curated teams: on-chain, and off-chain by way of a Telegram bot. We’re doing a UI redesign, enhancing interplay with shopper purposes and getting ready for a stay 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 identical 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 protecting 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 high 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 permits spam prevention for decentralized, nameless environments. In nameless environments, the identification of the entities is unknown. We’ve just lately revealed an explanatory weblog submit to get extra individuals excited in regards to the concept. We’ve completed analysis round “Feasibility evaluation for ETH2 Validator privateness utilizing RLN”. We’re engaged on productionalizing the “Personal on the spot chat app utilizing RLN and Interrep” mission. 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 through which the groups constructing or interacting with the Ethereum base layer are supported. The crew’s important 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 important 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 group, which led our crew to arrange frequent Group Calls. Throughout these, utility, infrastructure and tooling builders had been invited to debate the right way to finest assist protocol upgrades and supply a clean transition for his or her customers. Alongside these calls, the crew has given a number of talks and revealed a number of posts in regards to the altering Ethereum roadmap, corresponding to this latest all core devs replace, this piece in Bankless and this latest submit on the Merge and the applying layer within the EF Weblog.
Past protocol upgrades, the PS crew has taken on two main initiatives to make sure purchasers groups are nicely supported. First, a Shopper Incentive Program was introduced to provide groups Ethereum-aligned long-term incentives. This system supplies shopper groups with a set of 144 validators that they need to run utilizing their software program. Assuming groups maintain assembly sure efficiency benchmarks on mainnet, these validators are step by step vested to the groups, that are free to both liquidate them or maintain them working to gather rewards and charges. This program aligns groups with Ethereum, ensures they’re “dogfooding” their purchasers on mainnet, and that they maintain delivering performant software program.
Second, a Core Developer Apprenticeship Program was launched. This program offered stipends and mentorship to self-directed people who wished 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 contributors. Of those, at the very least 5 at the moment are working full time within the ecosystem. These preliminary cohorts have taught us rather a lot about what was good and what could possibly be improved with this system. Count on a revamped CDAP in 2022!
Lastly, the crew 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 working and accessible for the group 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 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 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 extra particulars in our article.
Sturdy Incentives Group
Authored by Barnabe Monnot
The RIG (Sturdy 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 may take a look at Protocol cryptoeconomics with the RIG, introduced by Barnabé at EthCC in July.
On the Proof-of-Stake consensus facet, 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. Thankfully, 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 time and is now a analysis assistant on the RIG, launched a sequence 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 vital date for us: the London arduous fork activated, and with it, EIP-1559. During the last yr, we have launched a sequence of notebooks presenting varied 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 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 crew in getting ready a web-based masterclass in validator economics, supported by a completely extensible mannequin 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 arduous 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 have been 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 assist, problem triage, and bug squashing throughout our Python instruments.

Portal
Authored by Piper Merriam
This yr has been a giant yr for the Portal Community. We began this yr with an concept and solely a free plan for the right way 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 nicely underway to launching the preliminary testnet which ought to evolve into a completely practical community by the tip of 2022.
The EF Portal crew has been working arduous on Trin, a portal shopper written in Rust. The EF Javascript crew has additionally been engaged on Ultralight, a portal shopper written in Typescript aimed toward being runnable within the browser. The crew from Standing.im has additionally been engaged on Fluffy, a portal shopper supposed for integration with the Standing ethereum shopper and pockets options.
Throughout this yr we’ve solved the beforehand unsolved drawback of the right way to distribute the present Ethereum State in a way that’s conducive to environment friendly storage and retrieval. We established the Portal Wire Protocol, an extensible base protocol that’s the basis of the entire networks making up the Portal Community. We additionally had the pleasure of working with a number of contributors of the Core Developer Apprenticeship Program who used the Portal Community tasks as a leaping off level for entering into Core Protocol improvement.
Safety [Security / Consensus Tests]
