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 12 months and the unimaginable progress throughout the whole Ethereum ecosystem.
As a extremely productive 12 months attracts to a detailed, there are just a few last 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 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 Group)
Authored by Hsiao-Wei Wang
Within the second half of this 12 months, the milestones in Ethereum consensus R&D included:
To align with The Great Renaming, we shifted parts to “Consensus Layer” from “Eth2” for clearer communication in the long run.
In early 2022, our staff will concentrate on serving to to ship the “The Merge”, essentially the most important consensus protocol improve ever. Luckily, we have now nice help from shopper groups, and others in the neighborhood working to make this a actuality! Within the meantime, we will likely 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 Update with grants totalling $7,794,000 for the quarter – and Q3 is coming quickly! You can too take a look at latest 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 significant 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 help. 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 staff publishes an summary of our quarterly roadmap objectives. See our Q4 product roadmap here.
Pleased holidays to all from the ethereum.org staff 😀🎄 As all the time, our vision 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 latest guests every month.
Content material updates
Ethereum strikes quick! In addition to updating a whole bunch of pages to make sure our content material stays updated and correct, we’ve additionally launched a bunch of latest content material:
Ethereum.org exists because of a whole bunch 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 have 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 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 really 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 similar interval final 12 months! To place this in perspective, that is equal to translating everything 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 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 adjustments to the upstream repo, which provides L2 community help and a wide range of internet 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 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 staff, the MACI staff & 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 develop into proficient Ethereum customers
- constructing further sources on operating 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 respect suggestions on our roadmap. Our guiding rules are based mostly on delivering essentially 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.
Ipsilon
Authored by Alex Beregszaszi
We have now created a team website to supply a transparent explainer and to comprehensively checklist our present and previous work.
It’s simple to inform from the next headers that within the second half of the 12 months the staff principally targeted on the EVM. It’s additionally essential to say that we have now 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 have now conducted 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 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 here, however the recording isn’t obtainable) and on the Ethereum Meetup in Berlin (slides, recording).
Different EIPs
EIP-2681 (Restrict account nonce to 2^64-1)
One in all our previous proposals, EIP-2681, was accepted throughout ACD#120. It codifies a restriction, which was already (partially) applied in observe in most purchasers. After acceptance we have now prolonged the Ethereum State Checks 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 achieved as we speak 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 suggests 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 is able to enable for extra optimised evaluation and execution, as a result of implementations would want 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 aspect two stories are noteworthy:
- Geth vs evmone compares the velocity of Geth and evmone utilizing the benchmarking suite in evmone.
- Geth & Go compiler explores the impact of the Go compiler model on the velocity of geth.
Based mostly on these preliminary outcomes, we have now 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 checklist of related PRs: 23952, 23970, 23974, 23977, 24017, 24026, 24031, 24120.
Comply with this link 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 staff additionally maintains a C++ ethash/keccak256 library, which is utilized by evmone and Silkworm.
The newest 0.8.0 release introduces a brand new technique for verifying the ultimate Ethash hashes in opposition to the block problem. That is each a usability and velocity enchancment. The strategy has been posted on Ethresear.ch.
Moreover, ProgPoW has been deprecated within the library.
Fizzy
The staff 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 selections we made.
- Weird quirks while testing WebAssembly exhibits a wide variety of edge instances we have now encountered whereas creating Fizzy. The speak additionally offers some potential options and explainers for these edge instances, in addition to how we have now prolonged the official WebAssembly take a look at suite to cowl them.
Formal Verification
Authored by Leo Alt
Within the second half of the 12 months the FV staff continued to concentrate on 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 examine 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 help the low-level name operate as an unsafe exterior name.
- Enhance counterexamples by reporting block.*, msg.* and tx.* values which can be essential 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 standard, our time has been break up between EIP evaluation/implementation, shopper optimization/upkeep and reviewing code adjustments proposed by the group.
In July, the London laborious fork, which included EIP-1559, was activated. The brand new fuel pricing scheme outlined by this EIP required many adjustments 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 have 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 have 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 observe to show geth into the ‘execution layer shopper’ of the merged execution+consensus (fmr. “eth1+eth2”) layers. In preparation for The Merge, we have now 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 staff has been engaged on a number of long-term tasks, comparable to implementation of Verkle Bushes, a beacon chain gentle 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 staff 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. If you’re you may see the next tracking issue to observe 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 immediately 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 available and on the Ethers.js entrance. Richard has simply posted an thrilling overview on the upcoming Ethers.js v6 library adjustments and updates on his blog.
Privateness & Scaling Explorations
Authored by Thore Hildebrandt
The Privateness & Scaling Explorations staff works to bridge the hole between cutting-edge analysis in zero-knowledge proofs, and utility improvement on Ethereum.
zkEVM
The aim of zkEVM is to run good 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 immediately into the zk circuits so a wise contract operating on L1 might be deployed to L2 with minimal modifications. This may 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 have now early benchmarks and an essential aim going ahead to deliver 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 gives prompt 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 damaging 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 occasions 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 aim of the challenge is to make it simple for any group to run their very own CLR spherical with clr.fund. This challenge has been very busy. Now you can deploy your personal quadratic funding utility with the clr.fund Deployer. Empower your group to decide on and fund its personal future, in a totally decentralized method. Take a look at our Subgraph and Documentation.
InterRep
Status is the important thing to belief. Individuals spend years build up their popularity 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 popularity transportable to increase the compounding advantages of trusted human interactions throughout the net. Check out this blogpost for the preliminary announcement and the repo. Previously quarter we have now 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 shopper purposes and getting 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 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 instances embody personal 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 have now new libs for dealing with semaphore proofs and identities. Implementation is now carried out on high of Halo2 and we’re getting it prepared for use within the browser.
RLN
RLN (Price Limiting Nullifier) is a assemble based mostly on zero-knowledge proofs that allows spam prevention for decentralized, nameless environments. In nameless environments, the identification of the entities is unknown. We have now not too long ago revealed an explanatory blog post 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 “Personal prompt chat app utilizing RLN and Interrep” challenge. 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) staff 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 staff’s principal 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 12 months. Past these, PS spent important 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 staff to arrange frequent Group Calls. Throughout these, utility, infrastructure and tooling builders have been invited to debate easy methods to finest help protocol upgrades and supply a clean transition for his or her customers. Alongside these calls, the staff has given a number of talks and revealed a number of posts concerning the altering Ethereum roadmap, comparable 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 staff has taken on two main initiatives to make sure purchasers groups are effectively supported. First, a Client Incentive Program was introduced to present groups Ethereum-aligned long-term incentives. This system gives 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 steadily vested to the groups, that are free to both liquidate them or maintain them operating 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 supplied 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 have 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 might be improved with this system. Anticipate a revamped CDAP in 2022!
Lastly, the staff 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.
Remix
Authored by Rob Stupay
Over the previous 6 months, the Remix staff has unscrewed the again of our app to do some in depth rewiring. First amongst these adjustments 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 more details in our article.
Sturdy Incentives Group
Authored by Barnabe Monnot
The RIG (Sturdy Incentives Group) welcomed new staff members and took part in lots of essential 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 aspect, Caspar, who joined us as full-time analysis scientist earlier this 12 months, discovered a difficulty with the present fork selection, written up as Three attacks on Proof-of-Stake Ethereum. Luckily, there’s a sturdy 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 below analysis. Take a look at 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 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 essential date for us: the London laborious fork activated, and with it, EIP-1559. Over the past 12 months, we have launched a sequence of notebooks presenting various 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 actual world, and opens new analysis instructions for enhancements to the rule.
The RIG was additionally carefully working with the cadCAD Edu staff in getting ready an online masterclass in validator economics, supported by a totally extensible model of Ethereum economics (in Python).
Snake Charmers [Python Ecosystem]
Authored by Keri Clowes
Within the second half of 2021, the Snake Charmers staff accomplished the adjustments wanted throughout the ecosystem to help the London laborious fork. This concerned wide-ranging, basic adjustments 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 academic content material, and positioned an even bigger emphasis on developer relations. And as all the time, there’s ongoing group help, challenge triage, and bug squashing throughout our Python instruments.

Portal
Authored by Piper Merriam
This 12 months has been a giant 12 months for the Portal Network. We began this 12 months with an concept and solely a free plan for easy methods to construct a peer-to-peer community that would 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 totally practical community by the top of 2022.
The EF Portal staff has been working laborious on Trin, a portal shopper written in Rust. The EF Javascript staff has additionally been engaged on Ultralight, a portal shopper written in Typescript geared toward being runnable within the browser. The staff from Status.im has additionally been engaged on Fluffy, a portal shopper meant for integration with the Standing ethereum shopper and pockets options.
Throughout this 12 months we have now 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 improvement.
