EF-Supported Teams: Research & Development Roundup

1 year ago 200

Friends,

As the twelvemonth of the Merge ends, we wanted to stock updates from galore of the Ethereum gardeners and EF-supported teams that achieved agelong sought accomplishments, some large and small, alongside the remainder of the ecosystem successful 2022. We each person a batch to beryllium thankful for, from the caller communities we've travel to know, to having each different done it all!

As always, this roundup bid focuses connected EF-supported teams whose members are moving to turn and amended Ethereum arsenic a whole. Included successful this variation are updates from galore teams highlighted successful the erstwhile report, and different caller and rotating groups.

Enjoy!

Consensus R&D (aka EF Research Team)

Authored by Danny Ryan and Hsiao-Wei Wang

This was an bonzer year. With the magic of lawsuit teams, DevOps wizards, testers, stakers, and the assemblage astatine large, we successfully merged ✌️🐼!

THANK YOU ALL for contributing to The Merge, massively reducing vigor consumption, and making Ethereum a much unafraid and sustainable protocol. Switching Ethereum mainnet statement mechanics to Proof-of-Stake (PoS) was a important milestone the Consensus R&D squad has been moving connected for galore years -- but this is not the afloat story!

Additionally, the Consensus R&D squad has been tackling emergent problems successful the MEV domain (e.g. proposer builder separation (PBS), MEV smoothing/burning), pondering information improvements to the beacon concatenation (e.g. azygous slot finality (SSF), azygous concealed person predetermination (SSLE)), and a full big of different statement probe – multi-dimensional EIP-1559, amended aggregation techniques, optimized applied cryptography, and more.

Next year, our squad volition proceed moving on, but not constricted to, the following:

  • Scheduled and tentative protocol upgrades
    1. Withdrawals functionality: this diagnostic volition alteration stakers to retreat their balances from the beacon concatenation to their execution furniture accounts. The consensus-layer halfway specs are nearing completion, and lawsuit teams are actively implementing and investigating the functionality.
    2. EIP-4844 aka proto-danksharding:
  • Other post-merge probe topics, e.g., proposer/builder separation (PBS), Verkle trie/statelessness, azygous slot finality (SSF), information availability sampling (DAS), interest marketplace refinement, azygous concealed person predetermination (SSLE), and more.

Cryptography Research

Authored by Dankrad Feist

The cryptography squad has taken an inaugural to marque Ethereum unafraid against quantum computers. Our squad members person contributed to a post-quantum signature strategy that is to beryllium standardized by NIST (National Institute of Standards and Technology). We proceed to enactment successful this absorption and physique a signature strategy that scales amended via aggregations. Further down the road, we whitethorn amended the scalability via amended aggregation techniques, oregon via antithetic hardness assumptions.

Fe-lang

Authored by Grant Wuerker

The Fe squad aims to supply the Ethereum assemblage with a harmless and effectual astute declaration programming language. The squad is liable for the plan of Fe-lang and the improvement of its halfway components, including the compiler, modular library, and tooling.

Over the past year, the squad has been focused connected adding connection features and preparing for our archetypal beta release. Below are the highlights from 2022:

Notable connection features:

  • Low-level intrinsic functions (0.12.0).
  • Nested structs successful representation (0.13.0).
  • Std room with evm and context modules (0.14.0).
  • Nested structs successful retention (0.14.0).
  • const folding (0.14.0).
  • Function statement labels (0.15.0).
  • Nested structs tin beryllium returned and passed into functions (0.19.1).
  • Braces! (0.19.1).
  • Traits and generic relation parameters (0.19.1).
  • Enums and match statements (0.20.0).
  • mut keyword (0.20.0).

Please spot the releases page for a implicit database of changes.

Tooling:

Other:

  • Yoshi has been moving connected a compiler backend specialized for astute contracts named Sonatina.
  • A fewer simple contracts were verified utilizing K.

Our apical priorities moving into 2023 are: archetypal beta merchandise (see: Fe's way to production), amended generic support, amended changeless support, and improvements to the modular library. We are particularly excited astir aboriginal Bountiful challenges.

Formal Verification

Authored by FV team

hevm

We’ve spent astir of this twelvemonth rewriting the symbolic execution motor successful hevm. This rewrite decompiles EVM into a customized intermediate practice and past issues SMT queries based connected the operation of the presumption successful this IR. This architecture gives america importantly much power implicit the details of the SMT encoding and makes the implementation of customized simplification and static investigation stages overmuch easier.

SMTChecker

In the past months we focused connected bug fixing and UX improvements. One important caller diagnostic that was added is the anticipation to usage the Horn solver Eldarica erstwhile utilizing the CLI oregon JSON interface from solc.

Yools

A fewer months agone we started Yools arsenic a impervious of concept, investigating the thought that verifying Yul alternatively of some Solidity and EVM bytecode has a batch of advantages. The preliminary results are rather promising, and we’re excited to proceed moving connected it successful 2023.

PolySolver, a solver for generalized polynomials

We started this probe subdivision with the extremity of verifying properties of polynomials from ZK apps/circuits. We precocious started applying it to R1CS circuits successful collaboration with 0xPARC and different organizations.

Geth

Authored by Péter Szilágyi

2022 was a tad slower twelvemonth erstwhile it came to shipping Geth features, but that is chiefly owed to the Ethereum Merge, which took up astir of the team's clip for testing, tweaking and mostly making definite everything ticks. That said, we bash person a fig of absorbing things we've been moving connected successful between.

Path-based trie storage

Perhaps the item upcoming diagnostic - astatine slightest for america arsenic maintainers - is Gary's path-based trie storage. We figured retired (a fewer years back) however to bash authorities pruning, but needed to get escaped of 1 blocker: accelerated sync. That meant shipping a caller sync protocol (snap) not lone for Geth, but besides helping different clients get it retired the door. With accelerated sync murdered, we tin yet alteration the state-trie retention exemplary successful Geth from hash keys to way keys. Whilst this is an insanely invasive alteration successful Geth, it volition yet let america to bash full, real-time humanities authorities pruning during artifact processing. The cherry connected apical is that afloat sync really gets faster. :)

TL;DR A tiny teaser from a portion back.

Light clients

One unfortunate of The Merge was airy clients. Previously, they lone needed to travel the concatenation of headers, cheque the PoW, and download Merkle proofs to entree the Ethereum state. In a post-merge world, however, PoW is gone, and frankincense airy clients cannot trust connected execution furniture headers unsocial to travel the chain. The lone viable solution is to travel the beacon concatenation headers, astatine slightest immoderate parts of it. Zsolt has been moving full-time connected reproducing the bare minimum beacon information structures successful Geth and exposing them successful the LES protocol to marque airy clients workable again. This besides requires collaborating with statement lawsuit teams to person entree to the needed information successful the archetypal place, truthful it takes a while. The upside is, however, that this enactment mightiness not lone hole airy clients, but besides alteration afloat (but non-block-producing) nodes to travel the concatenation without a statement lawsuit attached! Wouldn't that beryllium amazing, to lone babysit 1 programme again!

Shanghai

We're hardly past the merge, but protocol dev ne'er stops. The Shanghai hard fork is already semi-scheduled (exact contents inactive a spot debated), and Matt has been moving tirelessly connected the 2 main features: withdrawals and Ethereum Object Format. The erstwhile is already being deployed connected transverse lawsuit testnets. Withdrawals volition yet implicit The Merge, enabling staked ether and accumulated rewards to beryllium collected, portion the EOF enactment volition alteration a cleaner interior enactment of astute contracts, simplifying compiler enactment and besides enabling a fewer much precocious features to beryllium implemented. After the year's #TestingTheMerge, Marius is presently helping successful a akin relation getting Shanghai acceptable and retired faster and better.

Blob transactions

Possibly delayed until the Cancun hard fork, but already successful afloat improvement is the enactment for blob transactions (aka 4844), which would let the Ethereum web to make immense transactions (128KB a pop) that lone person an ephemeral lifespan (2-4 weeks). The intent of these transactions would beryllium to let furniture 2 solutions to perpetrate to and beryllium ample batches of information precise cheaply, without incurring an indefinite retention outgo connected each afloat nodes. This should marque L2s importantly cheaper and frankincense let Ethereum to - hopefully - onboard the adjacent watercourse of users. This enactment has been pioneered by Coinbase's Jessie and squad and is presently being picked up by Peter to integrate wherever imaginable and reimplement wherever Geth's DoS requirements necessitate a antithetic attack from the archetypal PoC work.

Verkle trees

Looking adjacent further out, Guillaume has been moving connected replacing Ethereum's Merkle trees with Verkle trees. This could extremity up being the astir invasive alteration ever done to the Ethereum execution layer, with implications crossed beauteous overmuch each facet of the network. The vantage of Verkle trees would beryllium greatly simplified authorities proofs, which mightiness conscionable alteration stateless clients. This year, helium enactment unneurotic a functional PoC, primitively moving successful a PoW testnet and presently a PoS testnet. For now, performance-wise, there's inactive enactment to beryllium done arsenic it's astir 2.5x slower than Merkle trees, but we'll get there. A batch of probe and improvement is being done trying to fig retired however to bash the modulation from Merkle to Verkle without pausing the full web (converting the information structures takes implicit a week currently).

Go-leveldb

Over the years we've had our ups and downs with utilizing go-leveldb arsenic our retention engine. We're everlastingly grateful to Suryandaru Triandana for creating it and helping america retired present and again! However, the task being unmaintained for galore years present near america without a viable upgrade path: we couldn't get our optimizations successful and immoderate upstream changes adjacent introduced DoS vectors, unfixed to this precise day. We've tried retired galore alternate databases (RocksDB, BoltDB, Badger, Postgres) and converged connected Pebble, a comparatively caller - but actively maintained - larboard of RocksDB successful Go. Jared is presently pioneering the integration works - which chiefly consists of getting that 1 oregon 2 missing features that we trust connected accepted successful the upstream Pebble projects. Switching retired LevelDB to Pebble, we don't expect show to change, conscionable for america to slumber amended astatine nighttime :P.

Built-in transaction tracers

Perhaps not the astir disposable feature, but we've worked a batch connected tweaking and extending Geth's built-in transaction tracers - which, if you missed the memo - present each tally natively successful Go and are rather speedy. Sina's been the superior contributor connected this front, besides making immoderate of the tracers configurable. A ample diagnostic we've been readying and are presently moving connected is live-tracing, which would let Geth to beryllium started with immoderate tracers explicitly requested connected startup, which would tally on with mean artifact processing, storing the tracing results connected disk. This should let users relying connected traces to not person to person the brittle 128 artifact model to rapidly hint thing earlier the authorities is pruned.

Docs & Website

Perhaps arsenic astonishing to you arsenic to america ( :D ), this twelvemonth we've started putting immoderate effort into getting our online docs successful a somewhat amended shape. Shoutout to Joseph for going done our blistery messiness of pages and trying to marque heads oregon tails of them. Within the aforesaid effort - with afloat acknowledgment to the ethereum.org squad - we've besides been moving connected a caller website for Geth. Don't expect each of a abrupt to person much - oregon antithetic kinds of - accusation published, truthful our caller website volition mostly travel the aged architecture, but should beryllium a invited refresher compared to the banal bootstrap template we threw unneurotic ages agone conscionable to person a downloads page. Contributions are welcome!

Aaand, that's a wrapper :)

Javascript Team

Authored by Holger Drewes

The EthereumJS libraries day backmost to arsenic aboriginal arsenic 2014 and correspond a continued effort to some modernize and support an uncluttered codification base. In 2022, we did a large circular of breaking releases:

  • Introducing autochthonal JavaScript BigInt support
  • Making larger structural changes specified arsenic extracting a "pure" EVM from the historically grown VM bundle code, and also…
  • Preparing the libraries for the Merge.

For 2023, determination is simply a batch astir the corner. We are actively moving connected an implementation of sharding (to beryllium precise: EIP-4844 "Shard Blob Transactions"), we’ve merged EIP-4895 "Beacon Chain Withdrawals" code, and program to implicit the 5 Ethereum Object Format (EOF) EIPs that are being considered for mainnet by gathering connected apical of the archetypal EIP-3540 implementation, enabling america to articulation an aboriginal EOF-focused testnet (likely successful January 2023).

Our EthereumJS (execution) lawsuit continues to mature. We urge listening to the PEEPanEIP podcast episode successful which our squad subordinate Gajinder talks astir however our lawsuit went done the Merge and a imaginable aboriginal airy client.

The lawsuit is present capable to service a afloat Ethereum testnet on with a Lodestar statement lawsuit instance. These efforts person culminated successful the motorboat of an aboriginal Pre-Shanghai testnet called Shandong aboriginal successful the year, which activated assorted EIPs being considered for Shanghai and was good perceived by the assemblage and different lawsuit teams.

We volition physique upon these experiences and motorboat a continued bid of dedicated "Community Testnets" passim 2023 which volition beryllium HF-independent and iterate rapidly with aboriginal EIP integrations and a beardown absorption connected (dev) assemblage needs. Stay tuned for an announcement here!

On Ultralight, our Portal Network implementation has importantly improved passim 2022, and we person present started moving connected PoCs that usage an Ethers provider, swapping retired the classical 3rd enactment RPC supplier (e.g. Infura) and already successfully serving (parts of) the JSON RPC calls successful a purely decentralized manner by utilizing a distributed Portal Network (!!). Continued results are promising, but we inactive request to cod much information connected "soft" factors specified arsenic performance, scalability, and web resilience. There besides are networking questions being addressed regarding a axenic browser usage of the developed solution.

And, regarding Ethers: Ethers v6 is conscionable astir the corner. Stay tuned for an announcement successful the coming weeks! 🤩 You tin drawback up connected what volition beryllium included by watching this YouTube Devcon talk from Richard.

Ipsilon (Execution Environment research)

Authored by Alex Beregszaszi

Last twelvemonth we yet launched our "website", wherever astir of our enactment tin beryllium observed. This twelvemonth we were besides active connected Twitter.

EIPs

This has been the "Year of EIPs" for Ipsilon. We person worked connected and published a ample fig of them. In bid of maturity:

PUSH0 and Initcode metering

EIP-3855: PUSH0 (providing a bully state improvement) and EIP-3860: Initcode metering (reducing DoS risks) are accepted for the Shanghai upgrade.

EOF

The radical of EIPs called EVM Object Format (EOF). This includes EIP-3540, EIP-3670, EIP-4200, EIP-4750 and EIP-5450. The enactment connected EOF started aboriginal 2021 and the steps were split, due to the fact that initially we did not expect to motorboat them together. Today this group, colloquially called "big EOF", is considered for inclusion successful Shanghai (or Cancun).

Twitter had a fig of bully threads (1 2 3) astir EOF, its features and benefits to the ecosystem. To sanction a few:

  • Large state savings with the reworked power travel strategy (static jumps provided by RJUMP and RJUMPI).
  • Useful caller instructions, specified arsenic RJUMPV to efficiently grip switch/jump-tables.
  • Structured contracts (separation of assorted codification sections and data) makes investigation (both automated and manual) easier, and frankincense tin trim information risks.
  • This operation besides allows for validation of contracts astatine deployment time, which reduces runtime overhead and risks.
  • The format is extensible and allows instauration of features, which were not imaginable until present (an illustration is EIP-663 and evmmax).

The existent enactment tin beryllium followed connected the EOF1 Checklist page.

Unlimited SWAP/DUP

Connected to EOF is EIP-663 introducing agelong awaited swaps and dups accessing greater stack extent -- this could region those feared "Stack excessively deep" errors Solidity is outputting. This alteration is projected for Cancun.

Others

Besides these we worked connected a fig of different proposals:

  • EIP-5000 (in collaboration with Solidity) introduces a MULDIV instruction, which would importantly trim the outgo of fixed constituent math, a cornerstone of galore (DeFi) applications.
  • EIP-5656 (in collaboration with Vyper) introduces a MCOPY instruction, which tin supply inexpensive representation copying astatine a 2-5x simplification successful outgo compared to today. This besides "deprecates" the identity precompile.
  • EIP-6046 is our (not precise good developed) effort to lick the "SELFDESTRUCT-problem".
  • evmmax (in collaboration with geth), the continuation of the evm384 project, introduces a tiny fig of instructions, which tin beryllium utilized arsenic gathering blocks to regenerate respective existent and aboriginal projected "precompiles".

These are not yet projected for immoderate upgrade, but possibly immoderate could marque it into Cancun.

evmone and fizzy

On the bundle front, EVMC 10.0.0 and evmone 0.9.0 were released, which enactment Paris (Merge) and among different changes rearchitect state accounting of refunds. These releases are utilized by Silkworm and by Solidity's investigating infrastructure. Accompanying, a number of releases of intx were made, mostly to amended velocity of arithmetic operations successful evmone.

We person besides made a agelong delayed merchandise of Fizzy v0.8.0, which contains the bulk of planned features. This includes built-in runtime metering. The enactment is paused connected Fizzy, for now.

Portal

Authored by Piper Merriam

The Portal Network is simply a multi squad task being led by Piper Merriam that aims to present lightweight protocol entree for the Ethereum network. Portal Network is simply a caller acceptable of distributed peer-to-peer retention networks that are designed for verifiable retention and retrieval of each of the information that makes up the execution concatenation and which is required for interacting with the Ethereum network.

The Portal squad has been moving each twelvemonth connected trin our lawsuit for the Portal Network. The Portal Network task arsenic a full has been softly moving towards gathering retired this wholly caller peculiar intent retention web and is connected way to present the archetypal mentation of this caller protocol to the Ethereum assemblage during 2023. We are presently focused connected delivering the “History” protocol which volition supply entree to each of the artifact headers and bodies from the past of the Ethereum execution chain. All of the 3 autarkic lawsuit implementations person matured this twelvemonth to afloat instrumentality the basal functionality needed to motorboat steadfast unrecorded networks.

In the past month, we deployed our archetypal mentation of “Portal Hive”, a “black box” investigating instrumentality that verifies the antithetic lawsuit implementations are each compliant with the protocol specifications. We besides deployed the archetypal iteration of “glados”, our web wellness monitoring instrumentality which actively audits the web to cheque the availability of content. These are large milestones for the project, marking the constituent wherever we modulation into having unrecorded networks with existent data.

The adjacent fewer months volition spot the past web coming online with much and much of the humanities information becoming disposable for retrieval. Our adjacent absorption volition beryllium connected implementing the Beacon concatenation airy protocol and serving the corresponding data. Following that volition beryllium the Ethereum State data, the canonical transaction index, and the transaction gossip network.

Privacy & Scaling Explorations

Authored by PSE Team

The PSE squad has been hard astatine enactment connected an ever-expanding database of projects this year. Below is simply a illustration of what PSE squad members person been moving connected - you tin find a much implicit database of ongoing projects astatine appliedzkp.org.

We’ve been fascinated with the possibilities of privacy-preserving societal applications enabled by a decentralized ecosystem of composable infrastructure. We’ve built and experimented with tools specified as:

  • Semaphore for creating anonymous identities to interact wrong customized groups.
  • Unirep for backstage non-repudiable reputation.
  • Interep, ZK-Chat for backstage communication, RLN for anonymous spam protection.
  • Crypt-Keeper for ZK individuality absorption and impervious generation. Proof of conception applications similar Zkitter and UniRep Social person fto america bring these experiments to beingness and spot however radical interact successful environments that consciousness familiar, but run successful fundamentally antithetic ways.

On the scaling front, we’re exploring however succinct proofs tin connection improved ratio successful a assortment of areas, from state costs to throughput and adjacent validating Ethereum itself:

  • BLSWallet provides components for an L2 astute declaration wallet with BLS signatures and aggregated transactions for reduced state costs.
  • Zkopru combines utilizing zk-SNARKs and optimistic rollups for low-cost backstage transactions connected L2.
  • The zkEVM Community Edition is one of galore zkEVM efforts putting zk-SNARKs to enactment to marque verifying L1 transactions easier and cheaper.

We’ve besides breached caller crushed successful anonymous voting and Public Goods funding. We supported respective teams adopting MACI (Minimal Anti-Collusion Infrastructure) for customized quadratic voting and quadratic backing rounds. Thanks to assistance from teams from ESP, Devcon, EcoDev, and more, we’ve supported section leaders successful the Ethereum assemblage adopting [zk]Quadratic Funding astir the world; each iteration was an accidental to amended the tools and process, with the extremity being much grassroots, privacy-first, quadratic backing operators that make worth for their community.

Many squad members showcased their enactment astatine Devcon VI successful Bogotá. Over a twelve PSE projects presented, arsenic good arsenic an all-team effort to signifier the Temporary Anonymous Zone assemblage hub, with an accompanying demo app wherever attendees interact anonymously arsenic portion of a Devcon VI Semaphore group.

PSE is simply a increasing assemblage and we invitation contributors and experimenters of each kinds! You tin travel america connected Twitter and Mirror, oregon articulation our Discord to get involved.

Protocol Support

Authored by Tim Beiko

The Merge was, by far, the astir important happening for Protocol Support to get close successful 2022. The squad helped with coordination, assemblage consciousness and a agelong database of miscellaneous tasks, from launching bordel.wtf to publishing the Merge Manual. On September 15th, we celebrated Ethereum’s palmy modulation to proof-of-stake! A fewer weeks later, we highlighted the enactment of merge contributors by signing them a song astatine Devcon.

Since then, we’ve been moving connected some Shanghai/Capella, which is focused connected Beacon Chain withdrawals, arsenic good arsenic the adjacent upgrade, centered astir EIP-4844, a.k.a. protodanksharding. This should support america engaged for astatine slightest the archetypal fractional of 2023. The 2 archetypal things you tin expect are devnets (and tutorials!) for Beacon Chain withdrawals, and the motorboat of the KZG Ceremony, for which we conscionable announced a grants round! For much connected these protocol upgrades, spot the latest AllCoreDevs update.

Beyond upgrades, the squad focused connected 2 different large initiatives successful 2022. The archetypal was launching Protocol Guild. The guild, whose plan was birthed successful a tweet, is simply a corporate of implicit 120 Ethereum L1 maintainers to which DAOs and individuals tin donate arsenic a mode of supporting the protocol. Unlike emblematic grants, focused connected organizations, funds sent to PG are routed to idiosyncratic contributors directly. To trial the idea, a 1 twelvemonth aviator was launched successful May. Six months in, PG has published a mid-pilot update, arsenic good arsenic its plans for 2023. Expect a new, governance-minimized mentation of PG, deployed to some L1 & L2s, with a overmuch longer vesting period.

The 2nd large inaugural PS undertook was (re)launching the Ethereum Protocol Fellowship (f.k.a. Core Dev Apprenticeship Program, oregon CDAP). EPF provides participants with stipends and mentorship to let them to dive heavy successful the “core dev” rabbit spread with the extremity of onboarding proficient contributors to lawsuit and probe teams. This 3rd cohort has implicit 20 participants, including a fistful that enactment permissionless-ly, moving connected assorted projects including MEV, airy clients, relationship abstraction and sharding. Once it wraps up, astir ETHDenver, we’ll instrumentality clip to bespeak connected however it went and however it tin beryllium improved. We expect to tally different cohort that volition statesman implicit the summer.

Last but not least, contributors to the Ethereum Execution Layer Specification, a.k.a. EELS, person precocious joined the PS team. The enactment connected EELS volition supply Ethereum’s EL with a much accessible spec, from which it’s casual to make trial vectors. It’s besides a important measurement successful aligning however changes are specified crossed the execution and statement layer, fixed the second already has a similar spec. If you were reasoning of penning an EIP, it’s worthy giving EELS a look arsenic good — it mightiness beryllium easier to usage a Python diff than reimplementing a ample chunk of Ethereum successful markdown pseudocode!

Remix

Authored by Rob Stupay and Yann Levreau

IDE Updates:

We began the twelvemonth astatine v0.21.0 and person conscionable released v0.29.0. For each the details astir what has been updated connected the IDE delight cheque our extremity of twelvemonth article.

Process

The Remix squad has been integrating User Centered Design methodologies into our workflow. We’ve sought idiosyncratic feedback done our “Ask Remix Anything” calls, idiosyncratic individual interviews, from our enactment channels and done societal media outreach. We’ve besides incorporated beta testers into our merchandise process. These caller channels of feedback person been precise helpful.

Dogfooding

We dogfooded the IDE connected a fewer projects. At ETHDenver we hacked a token-curated, upgradable playlist and opus minting dApp for Rocky Mountain Public Media. Then we developed Remix Rewards, an ongoing programme to reward Remix contributors, beta testers, and UX probe participants with NFT badges. Finally, we created Remix Challenges, quizzes that usage ZK proofs. We past began utilizing the Remix Challenge quizzes successful our workshops; they marque an fantabulous demo task for introducing Remix’s capabilities. Through utilizing Remix successful each of these demo projects, we were capable to find immoderate areas wherever we could amended the instrumentality and then… we did.

Workshops & Talks

Throughout 2022, Remix squad members gave workshops and talks at: ETHDenver, Devconnect, Solidity Summit, Kuala Lumpur Ethereum Meetup, EthCC, SmartCon, EThSafari, Devcon (one of which was successful Spanish), ETHVietnam, and ETHIndia.

A preview of 2023

Here are immoderate highlights from our 2023 Roadmap:

  • Improving Remix’s show with a dilatory net connection
  • Improving Remix’s wide performance
  • Remix for “low code” usage cases
  • Adding caller features and gathering requested features
  • Giving much workshops

Robust Incentives Group

Authored by Barnabé Monnot

This year, our squad participated successful aggregate conversations connected the economics of Ethereum with manufacture partners arsenic good arsenic world grantees and collaborators. We organized ETHconomics successful April during Devconnect, a gathering of manufacture researchers and academics who discussed each facets of protocol economics for the Ethereum basal furniture and rollups. In December, we co-organized the archetypal Columbia Cryptoeconomics Workshop. We besides precocious released RIG Open Problems, an inaugural to decentralize our probe process.

Among different works and talks listed connected our homepage, present are different topics that kept america engaged this year:

Snake Charmers [Python Ecosystem]

Authored by Keri Clowes

In 2022, we made galore breathtaking changes crossed our libraries. We released our archetypal beta versions of web3.py v6, which opened the doorway for galore long-awaited breaking changes passim our stack. Those breaking changes included:

  • Streamlining the eth-abi API
  • Dropping enactment for deprecated Python versions (3.5 and 3.6)
  • Deprecating camelCase syntax successful favour of snake_case (and tons more)

Of peculiar note, robust asynchronous enactment is present disposable via the AsyncHTTPProvider. A afloat database of changes to web3.py tin beryllium recovered connected the release notes leafage of the documentation.

The mediate of the twelvemonth brought america The Merge and truthful eth-tester, web3.py, and py-EVM each got updates to enactment the Paris hard fork. Additionally, we shipped immoderate caller features to our ENS module, including enactment for ENSIP-10 and the Cross-Chain Interoperability Protocol.

We’ve besides been focused connected making web3.py arsenic extensible arsenic possible, truthful we added APIs for customized modules and methods. This enables users to easy grip non-standard JSON-RPC methods, oregon adjacent adhd a afloat L2 API. We’ve besides spent clip modernizing our libraries this year, including adding enactment for Python 3.10 and 3.11, and modernizing our merchandise processes.

We enactment an accent connected developer relations this year, arsenic Marc continues to prioritize acquisition contented chiefly focused connected web3.py patterns and internals, geared astatine a wide scope of developer abilities. These blog posts astatine snakecharmers.ethereum.org.

He besides spoke astatine Devcon VI and astatine the inaugural Pychain conference.

We launched a developer survey to summation penetration into the types of users that we have, and the ways successful which they usage web3.py and our supporting libraries. Participate successful the survey here.

In 2023, our squad plans to:

  • Refine the asynchronous providers successful web3.py, and merchandise a unchangeable web3.py v6.
  • Implement changes to our stack of libraries to enactment the Shanghai and different web upgrades that travel successful 2023, including changes to clients and astute declaration languages.
  • Integrate the idiosyncratic feedback gained from the survey and different feedback channels into our roadmap.
  • Continue to prioritize users by producing acquisition blog posts, and presenting astatine assorted events.

Security [Security / Consensus Tests]

Authored by Fredrik Svantes

We started this twelvemonth with the wide nonsubjective to marque The Merge a occurrence from a information perspective, truthful successful the archetypal fractional of the twelvemonth and up until The Merge, our efforts were chiefly aimed towards investigating and improving information wherever imaginable successful the protocol and clients. At The Merge, nary large issues were spotted and everything appeared to spell precise smoothly.

During this twelvemonth we person worked connected galore things starring up to and beyond The Merge. Some of our enactment started with a merge menace assessment, and has been related to fuzzing utilizing tools specified arsenic Antithesis, Nosy Neighbor, Beacon Fuzz, Engine API Fuzzer, EL fuzzers and different fuzzers.

We person besides manually audited clients, libp2p, L2s, Bridges, validator appliances, mev, worked with outer auditing companies for immoderate audits, researched ways to trim DDoS risks of validators, and more. One of the possibly much publically seen improvements was our importantly accrued bounties (4x), but we person besides released tools specified arsenic Nosy Neighbor and Secure Drop.

The information squad besides intimately worked with the protocol enactment squad and the lawsuit teams successful a play merge investigating telephone and has been moving its ain validators for the testnets.

Lastly, the squad has fixed respective talks and published respective posts astir security, specified as

Continue keeping an oculus retired for our “Secured” blog posts if you privation to larn much astir what we’re up to.

In 2023, the squad volition absorption on:

  • Internal information audits of Capella/Shanghai
  • Further improving our investigating capabilities
  • Coordinating an outer information audit of Account Abstraction
  • Coordinating and communicating vulnerability reports done the Bounty program
  • Internal manual spec and lawsuit audits
  • Running and improving fuzzing infrastructure
  • Internal information audits of Layer 2/Bridges
  • Holding lawsuit information calls to further collaborate connected security
  • Coordinating outer information audits

Solidity

Authored by Franziska Heintel

Throughout 2022, we published 6 Solidity releases with the pursuing highlights:

Besides the ongoing enactment connected the compiler and language, we besides engaged with the ecosystem:

  • We organized the Underhanded Solidity Contest 2022, which was a large success. The extremity of the ontest is to constitute seemingly guiltless and straightforward-looking Solidity codification that really contains malicious behaviour oregon backdoors. Check retired the Board of Fame for each winning submissions!
  • In April, we hosted the Solidity Summit, a one-day conference, arsenic portion of Devconnect successful Amsterdam. The Solidity Summit is simply a collaborative lawsuit focusing connected the aboriginal of Solidity. Find a recap of the lawsuit with afloat docket and links to each speech recordings here.

If you privation to get up to velocity with caller Solidity developments, present is simply a enactment of talks the Solidity halfway squad members gave successful 2022:

In December, we shared “Solidity Core Team Updates” connected the Solidity blog, summarizing the astir important events successful the halfway team.

Last but not least: The Solidity Developer Survey 2022 launched connected December 7! If you are a Solidity developer, delight enactment america by providing your insights and instrumentality 10 minutes to instrumentality portion successful the survey here. The survey closes connected January 7, 2023.

ZoKrates

Authored by Thibaut Schaeffer

2022 was a bully twelvemonth for ZoKrates:

  • It started with the implementation of a Solidity verifier for the Marlin proving strategy by Nirvan Tyagi, a large archetypal publication to the project.
