TrustMesh A2A — Open Agentic Web Protocol

Hackathon Submissions

• Cognizant Open Agentic Web Challenge ($13,000 USD Cash Prize Pool)
• DoraHacks Terminal 3 Build+Scale Agent Micro Grant ($1,800 USD)

Core Innovations

1. Open Agentic Web Discovery (/.well-known/agent-card.json):

   • RFC-compliant schema enabling zero-friction agent-to-agent capability indexing.
   • Declarative skill registry, authentication multibase keys, and SLA policies.

2. W3C Ed25519 Capability Credentials & Attenuation Engine:

   • Native Node.js crypto & WebCrypto Ed25519 signing.
   • Deterministic canonical JSON serialization.
   • Multi-hop delegation chains with strictly monotonic depth limits and action scope attenuation.
   • Temporal validation (issuanceDate, expirationDate).

3. Deterministic SLA Settlement & Micro-Escrow Hashlock:

   • Performance-bonded execution receipts.
   • Latency-enforced escrow state transitions (PENDING -> SETTLED / SLASHED / REFUNDED).
   • Replay protection and SHA-256 preimage verification.

4. SDK & Command Line Interface:

   • bin/cli.js: Key generation, agent card creation, capability issuance, and verification.
   • Standalone live browser simulator: docs/index.html.

Test Results

• 19 automated unit & security tests executed via Vitest with 100% pass rate.
• Covers cryptographic primitives, base58 multicodec, signature forgery detection, scope expansion rejection, and SLA slash penalties.
