UCAN & WNFS 🌳 What, Why, and Integration 🦜
Decentralized Digital Identity DIDs 🛂
Decentralized Digital Identity DIDs
Decentralized Digital Identity DIDs • One or more public keys • Truly “universal” user IDs • Agnostic about backing • Self-attesting • Database • Blockchain • For users, devices, and more • Relates to verifiable credentials
Decentralized Digital Identity did:key & UCAN
Decentralized Digital Identity did:key & UCAN • “Just” a public key (e.g. RSA, EdDSA)
Decentralized Digital Identity did:key & UCAN • “Just” a public key (e.g. RSA, EdDSA) • Self-certifying, extremely flexible
Decentralized Digital Identity did:key & UCAN • “Just” a public key (e.g. RSA, EdDSA) • Self-certifying, extremely flexible • Well suited to capabilities/authZ (vs identity/authN)
Decentralized Digital Identity did:key & UCAN • “Just” a public key (e.g. RSA, EdDSA) • Self-certifying, extremely flexible • Well suited to capabilities/authZ (vs identity/authN) • Made practical with UCANs • did:key → authN • UCAN → authZ
Decentralized Digital Identity Variety
Decentralized Digital Identity Variety • Microsoft ION, 3Box’s Ceramic, Sovrin, did:key, and well over 400 others
Decentralized Digital Identity Variety • Microsoft ION, 3Box’s Ceramic, Sovrin, did:key, and well over 400 others • Can federate, but hasn’t been done yet win the wild • Fission working towards interop with ION as first step

UCAN Tradeoffs & Hybridization
UCAN Tradeoffs & Hybridization • Pure ACL, reactive • Centrally view who has access to what • Check on every request, bottleneck • At-will revocation • Access rules grow in complexity • More complex provisioning
