Guess guest90 disappeared. I would also be interested to see some real world implementations of protocol implementations in other domains. I have harked on about how a cryptonote/Monero digital identity scheme would be very beneficial.

Better than building it on bitcoin it would seem

Or Ethereum

At least one incarnation uses Hyperledger which has some ZK based stuff, but it's a bit of a privacy shitshow at the moment

*Hyperledger Indy

Does the curve Monero uses support something like non-hardened key derivation?

e.g. given a public key K, derive another public key K', but without being able to derive K from K'

yanmaani: there is hash to point

UkoeHB: Will that get me the same behaviour with the private keys?

In Bitcoin's curve, you can go from a public key to another public key

and you can go from a private key to another private key

and k_childG = K_child

specifically like in github.com/bitcoin/bips/blob/master…#Child_key_derivation_CKD_functions

That, I don’t know. Seems unlikely
