Will do.

Which C or C++ library would you recommend to use to convert between them?
Can you share what you think that DID Document would like that includes
both representations? I don’t even like using base58 for the public key as
no Bitcoin implemention uses base58 for public keys at all — bitcoind only
used hex.

Also, do you agree that this DID Document should not include information
about the base58hash of the public key of the tip that is used in the BTCR
Method to revoke or rotate this DID Document? My challenge is only a DID
resolver can do this, so why put it in the DID Document at all?
