Authenticating secp256k1 and other keys

[reisepass]

Is anyone else intersted in Authenticating users based on them controling a BitCoin or Ethereium private key?

I have seen some work on converting the typical hex keys into JWK and then generating JWT’s but on the verification side most JWT libraries do not suppor the curve secp256k1 .
