Workshop Notes: SIWE->CACAO->UCAN
Background (JT: @oed, BZ: , B, WC: @wyc)
- Sign-In with Ethereum fields can be fully represented as Chain Agnostic Capability Objects (CACAOs).
- UCANs are JWTs
@oed: Can we harmonize the way we represent the structure in IPLD? Boris: UCANs are broader than blockchain, we want to represent all types of capabilities. We want adoption and interoperability.
BZ goes over delegation.
- Today, the parent capabilities assume that CIDs listed are also UCANs.
- We could use the extension data to contain the interpretation rules for SIWE-CACAO.
- The attenuations are one per resource, with delegated session key in the
aud
.
