These specs might help with the optional JWS signatures on Agent Cards; https://news.ycombinator.com/item?id=47455774 :
> Distributed DAG state with W3C VC and W3C DID (did:tdw did:webvh) microledgers and maybe W3C PROV would probably work, but the opcode cost of the control layer and the opcode cost of each dispatched, signed code object, and the byte cost for data storage, and messages.
> Agent isolation with WASM and now wasmtime-mte . Opcode costs with eWASM or similar?
AP2 already has W3C DIDs instead of optional JWS?
Has AP2 been similarly reviewed?
