Description

The goal of this milestone is having

• using the noise framework

• Ethereum Wallet address used to derive authentication key for noise

• Design an Ethereum address-based 1:1 chat

  • should be transport agnostic
  • toy eth chat: https://rfc.vac.dev/spec/20/
    • this milestone requires forward secrecy (see limitations section of the toy eth chat RFC)
  • consider using https://eips.ethereum.org/EIPS/eip-5564

• Naive Groupchat functionality (using n 1:1 chat channels)

• involve metamask here (metamask im team)

• a follow up milestone will cover running Ethereum chat on top of Waku

• follow up goal: develop this into an EIP

Justification

Deliverables

• specification (RFC) of a secure Ethereum-based chat protocol
