### Description
|
|
|
|
|
|
|
|
|
|
The goal of this milestone is having
|
|
|
|
|
|
|
|
|
|
* using the [noise](http://noiseprotocol.org/noise.html) 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
