We do not use Hyperledger Aries, but thanks for showing us. I have a blockchain background, and Keyri is somewhat inspired by blockchain concepts, but we've stayed away from blockchain-based solutions for privacy reasons. The pseudonymity of traceable blockchain transactions (in the auth scenario, authentication request transmissions) do not provide adequate privacy. Apologies if I'm misinterpreting Aries - perhaps its ledger is not publicly viewable. I have other objections to blockchain-based identity solutions, but privacy is the main one.
Then there are other passwordless auth solutions employing "private blockchains". That term basically means "database" in my mind and is obviously not ideal from a privacy perspective.
