Proposal: RSA GitHub Wallets POC

[hcheng826]

General Grant Proposal

• Project: RSA GitHub Wallets POC
• https://github.com/privacy-scaling-explorations/acceleration-program/issues/11

Project Overview :page_facing_up:

Overview

Use the RSA signature that GitHub supports to generate off-chain zk proof from the commit message or pull request data, just like how zk email generate the proof from email payload. Use the zk proof to integrate with AA wallet and perform operations. The circom circuits supporting succinct RSA signature proof is already made by zk-email. We can also use their relayer to generate and submit proofs to the AA bundlers.

Project Details

Provide as much detail as possible about the project's expected final state.

• Scope of Work: PoC, Blog Post or Spec on HackMd

• Key Features

  The RSA GitHub Wallets POC project integrates several core components to create a seamless and secure system for authorizing transactions via GitHub operations:

  • GitHub User/Wallet Account Owner: Users hold GPG keys to submit signed commits to GitHub. These signatures are used to generate off-chain zk proofs for on-chain verification.
  • Relayer: A crucial component that listens to commit events, parses commit messages, and generates zk proofs from them. The relayer then submits these proofs to the AA bundler. Additionally, we will experiment with the possibility of using GitHub Actions as part of the CI/CD pipeline to execute relayer tasks.
  • Wallet Account on Chain (AA Smart Contract): This on-chain component verifies the zk proofs generated from signed commit messages and executes the corresponding user operations (userOp).
• Use Cases and Potential Impact
  • Developer Transactions: Streamline project financing by allowing developers to authorize transactions directly from GitHub.
  • Collaborative Funding: Facilitate collective fund management through shared AA wallets, with transactions authorized by GitHub activities.
  • Community Incentives: Encourage open-source contributions by enabling commits or PRs to trigger payments from a project's AA wallet.
• PoC/MVP or other relevant prior work or research on the topic
  • ZK email and ZK email wallet

I'm looking for a reviewer

[ETHorHIL]

Hey, I can take this.

[hcheng826]

@ETHorHIL Thanks! do let me know if there's any feedback!

[ETHorHIL]

The proposal looks sensible. We can move on.

[hcheng826]

@ETHorHIL I have the first draft for milestone 1 of background research and design here: https://hackmd.io/@THUxtt18Qeiwn2vtWvmVDg/H1B5WKbxC I read the guide Looks like I should wait for feedbacks or approval before moving on to the next milestone? Let me know if I can go ahead or there're any feedbacks. Thanks!

[NOOMA-42]

@hcheng826 we'll proceed to another round of review by @mitsu1124, please kindly wait for further notice
