Web3 Galaxy Brain: Jose Aguinaga on Passkeys, MPC, and AA Wallets

matallo.eth · 2023-09-29T21:52:23.000Z

My guest today is Jose Aguinaga. Jose is Head of Digital Custody Services at SEBA Bank in Switzerland. He was previously Head of Engineering at HOPR. Jose is also the creator of passkeys.is and mpc.is, two valuable educational resources that describe and demonstrate passkeys and multi-party computation, respectively. On this episode, Jose and I go deep on elliptic curve cryptography, ECDSA, passkeys, homomorphic encryption, distributed key generation, account abstraction smart wallets and much more. If you're interested in the frontier of self custody smart wallet user experience, this episode is for you. It was a pleasure talking to Jose who is knowledgable, humble, and generous. I hope you enjoy the show. As always, this show is provided as entertainment and does not constitute legal, financial, or tax advice or any form of endorsement or suggestion.
