Feel free to add details about yourself and relevant links here ahead of time - Boris Mann, @bmann, Fission https://fission.codes - Patrick Woodhead, @patrickw, Protocol Labs Retrieval Markets ipns://retrieval.market - Jon Schwartz, [@j_schwartzz](https://twitter.com/j_schwartzz), GLIF - https://apps.glif.io ### Overview Boris will present some of his previous work in the space, and ideas for moving FIL Accounts forward. This is a kick off meeting, so nothing is set in stone yet -- please bring your own ideas and what you want to see as outcomes. The FIL Accounts presentation from last year's labweek will be used as a starting point and overview: https://docs.google.com/presentation/d/1AT3npAPhZJeJhJxRpWUFQelALV7J8dm92EeLaLUa_r0/edit?usp=sharing ### Communication Channels The [#identity channel in Filecoin Slack](https://filecoinproject.slack.com/archives/C02JJ644V5W). HackMD for meeting agenda / notes? Luma https://lu.ma for ongoing meetings / calendar invites - will look at either a "Filecoin" Luma community and/or an "FIL Accounts" one? TBD Open question: best place for long form discussion? ### App Login Spec FIP We'll want to document how to work with wallets and RPC endpoints and apps, and turn it into a Filecoin Improvement Proposal (FIP). Can we learn from other sovereign chains here? Are there any "leapfrog" opportunities -- e.g. around account abstraction? Also, FIL has built in multisig support at the chain level -- does this offer any interesting opportunities? SIWE is "Sign in With Ethereum" -- but can also be read as "Sign in With Everything". Can look at aligning with this spec too. Chain Agnostic Standards Alliance (CASA) is happening Sept 15th in Berlin. A `did:fil` and some other FIL chain specs can be added there. DAGHouse (Web3Storage, NFTStorage) are actively adopting UCAN, which helps with decentralized auth / offchain delegation (disclaimer: and was developed by Boris/Fission team, it is now a community working group https://github.com/ucan-wg). * eg. UCAN support in Estuary for end-to-end FIL support ### FIL.js We'll need to build a standard "FIL.js" library that implements the App Login spec. App developers can add this to their app to enable FIL-powered logins. Looking at related chain implementations like web3.js, ethers.js, [cosmos.js](https://github.com/cosmostation/cosmosjs) -- we may investigate how to _include_ FIL support in there? Relevant libraries: - https://filecoin-shipyard.github.io/filecoin.js/ - https://www.npmjs.com/package/@glif/filecoin-wallet-provider ### Wallets in the Wild * Glif * Brave * MetaMask Snap * Trust Wallet -- no login capability, but could likely support through WalletConnect v2 support ### RPC Endpoints Glif team have a full featured endpoint, ARG/ecosystem team have one. Need to talk to Infura, others, about availability / turning on endpoints which accept signed transactions for FIL transfer. ### FVM - EVM Some discussion about current state. * likely to have an EVM-compatible RPC endpoint with "shims" for FIL native translation * open questions around needing a FIL account first (for devs) -- as well as supporting EVM-flavoured accounts/wallets natively ## :closed_book: Follow Ups  - [ ] Schedule next meeting - [ ] Setup FILAccounts WG Github Org ## Notes  Jenny - FIL Slack * working with Lotus * TPM of Lotus Dietrich * Browsers and Platforms * W3C * Interop & standardization Ally * Dev advocate FIL Foundation * FVM team Raul * Lead of FVM project * Learn more * Account abstraction Alexandru * contribute to a lot of projects in FIL * learn about identity -- make active contributions * FIL.js ? Get link Jonathan * Glif project, and wallets * help with login Taosheng * come from * contributed projects to FIL * reputation Pando project * implementing DIF Michael * Sonr -- looking to build user owned internet * learn more about WG * working on project to work on bridge / Cosmos Steven * work at Fission * WalletAuth Dragan * FVM team * TPM Eva * work on ecosystem collabs at Outercore * learn what to do RFPd JeffG * work at Fission * head of product * webnative Andy * work at Fission * web3 ### Immediate Future Jonathan * Use DIDs and data backpacks -- self sovereign -- separate this out * How to make it easier to build on the FVM without having to rebuild a wallet Boris * FIL accounts first Dietrich * Brave not yet hooked up to FIL provider * WalletConnect * Universal Wallets CCG Scope * FIP defining app signin * RPC support for signing * FIL.js providing injecting of a FIL provider Jonathan * making it easier for devs to work with any wallet * FILSnap * Ledger * DevX or -- create wrappers ### Filecoin.js * not about users or wallets * everything about signing, JSON-RPC API * not saying it should be the only javascript library * putting a team to work on FIL.js * looking at other implementations -- e.g. ethers.js * identity * https://github.com/filecoin-shipyard/filecoin.js ### Account Abstraction Generally speaking -- any contract on chain, to act as a sender of a message vs. Externally Owned Account (EOA) Deep changes to protocol, including mempool, validation of message Main motivator is FEVM -- allow for Filecoin chain to validate Ethereum-flavoured wallets * RLP encoded * Ethereum signature scheme * Filecoin already supports SECP-256k1 * alternative solution -- introduce Ethereum knowledge in baseline Filecoin protocol -- which would be coupled to Ethereum evolution * eg also things like Multisig not inheriting the last sender of transaction * social key recovery * with account abstraction, do a recovery scheme -- (this whole thing is smart contract wallets elsewhere) Two channels on Filecoin Slack * FIL-FIPs, FVM * no FIP yet Authentication of actors -- validate a give message Boris: don't need RPC for _just_ signing ### Chain Agnostic Standards Alliance (CASA) * who is the CASA "rep" for Filecoin ecosystem * file issues to define FIL addressing and other standards * Eva? Tech support from Boris, Jonathan * help from Dietrich on standards ### UX Flows Jonathan -- need to look at flows, around EVM and FIL accounts Cosmos interop as well Boris: Fission can contribute some UX flows * Ryan wrote this https://fission.codes/blog/wallet-stack/ Boris: Link to Kepler / Cosmos + EVM Raul: * offline ? * instantiate a WASM actor * light clients ### RPC Need to have community RPC providers FEVM -- JSON-RPC shim needed Pockt Network --> https://www.pokt.network/ -- round robin RPC providers * Eva has been talking to them ## Chat Log :::spoiler Chat Log 09:01:33 From Raúl Kripalani to Everyone: risky question to ask 09:02:13 From Dietrich Ayala to Everyone: what a rad group 09:02:31 From jennijuju to Everyone: omg so many favs here 09:02:35 From Dietrich Ayala to Everyone: WASN'T ME 09:02:44 From Boris Mann to Everyone: https://hackmd.io/HtiQe4oASsaBLf5NLfc8sg 09:02:45 From Dragan Zurzin to Everyone: Ola 09:03:21 From Ally Haire to Everyone: great agenda 09:03:22 From JSchwartz to Everyone: Sup y’all!
