Investigate libp2p for multisig

[robvanmieghem]

python libp2p is still under development and still missing a lot of features: https://github.com/libp2p/py-libp2p Activity on the pylibp2p seems also very low

Ed25519 private/public keys can be used so hopefully we can derive libp2p addresses from a stellar address

if you are only looking to have python peer using the same version of py-libp2, you might be able to get away with it. But indeed this implementation is still in very early stage and not compatible with the go reference implementation (or any other implementation as far as I know)

libp2p uses multiaddr, which is just a format to looks like /ip4/127.0.0.1/tcp/80/. There is no cryptography involved there. I think what you are referring to when talking about public/private key is the peer ID that can be looked up using the DHT to connect to a peer without knowing it's actual IP/port, AKA peer discovery

Indeed

peerdiscovery is missing in the python implementation unfortunately

unsupported platform

tried upgrading some libs but keep having this

So at least on osx, using python libp2p is not an option for now even though creating a peerid from your stellar address(secret) in a host would be very simple:kp=libp2p.crypto.ed25519.create_new_key_pair(stellar_sdk.strkey.StrKey.decode_ed25519_secret_seed(wallet.secret))

[robvanmieghem]

instead of using python, implementing it in go would be a very good solution for issuance, not for normal wallet multisig since those wallets are implemented in python
