Sorry I'm sick, which is reason why it take so long :)

Using NIP-12 for storing hashes on relay with tag “d”, in this state i just upload and search

It's just python script with arg “-um email@adress.com” for upload to relay and “-dm email@adress.com”

On damus relay (one hardcoded) is i think 5 pubkeys for email “x@y.z”

On todo: expiration on relay, DM for verification, I probably change discover protocol, that we upload hash(hash(email)) instead just hash(email), because that way we can use hash(email) as encryption key for IM and so we can automativaly check if other side realy know email adress.
