Eth-PM using Noise + Library

[weboko]

There was a question in Discord about broadcasting messages from an Ethereum node.

I thought it might be a nice catchy example to have implemented and put into our guide section especially considering there are a lot of L2 chain projects happening.

wdyt @LordGhostX @hackyguru ?

Based on what I gathered from the conversation:

• The user wants to establish communication between two files/cmds/nodes (clients).
• They have identified Waku as a promising solution (which is correct).
• The proposed solution involves setting up a nwaku/go-waku node and connecting both clients (JSON-RPC, SDKs).

Are you inquiring about the possibility of providing an example that demonstrates two clients communicating or proxying messages to/from an Ethereum node?

PS: The documentation is being relocated to https://docs.waku.org/ and is still in development.

Proposed way forward:

(1) Draft a protocol that is similar to ETH-PM but uses noise.
(2) Write a bounty with few outputs:

• implement protocol above as a library
• PoC that uses the library

We can then write a guide on how to do wallet to wallet communications.

In general, any good ideas for a guide can be recorded as an issue in docs.waku.org repo.
Any good ideas for PoC can be recorded in bounties repo.

After starting to draft the protocol: vacp2p/rfc#606

I don't think a bounty is a good idea. However, I do think it'd be good to create a library and use it in Eth-PM.

I'd also think that we should move the example to light push + filter + store. The usage of store will make the UX better to retrieve the static public key of the users and as we know, Relay in the browser is not yet that useful.

Finally, let's aim to do this work in 2024. Focus for now should be on making codebase production ready.
