A2A v1.0 Extensions — projectmaya.deoscomputing.io

Project Maya's two extensions to the A2A v1.0 wire protocol.

• ucan/v1 — UcanSecurityScheme. UCAN delegation chains as an A2A authentication scheme. Capability-rooted instead of identity-rooted; the credential carries the authorized action inline.
• substrate-receipts/v1 — SubstrateReceiptEnvelope on Task responses. Substrate-signed, Bitcoin-anchorable receipts that let a client durably prove an action was taken on their behalf at time T with authorization Y.

Both extensions are independent: an agent may adopt either one without the other. They compose: a UCAN-authenticated request produces a receipt whose capability.chain reflects the inbound UCAN chain.

See /a2a for the integration overview.
