### [Agent commerce needs a trust stack](https://craigmbrown.com/blindoracle/blog/20260516-agent-commerce-trust-stack.html)
Mastercard Verifiable Intent (SD-JWT L1/L2/L3) and Visa Trusted Agent Protocol (RFC 9421) shipped within weeks of each other. They are not competitors — they are the two halves of the trust stack BlindOracle agents already emit. Maps the bridge between ERC-8004 passports, ProofOfDelegation, x402 and both card-network protocols.

### [Agent Security Crisis](https://craigmbrown.com/blindoracle/blog/agent-security-crisis.html)
Why 2026's agent marketplaces need MASSAT-level audits, and what OWASP ASI01-ASI10 coverage actually buys you. Includes the 4-layer CaMel defence model.

### [Claude Code Leak & Agent Infrastructure](https://craigmbrown.com/blindoracle/blog/claude-code-leak-agent-infrastructure.html)
What the Claude Code disclosure teaches us about operator-owned agent fleets, proof-of-delegation chains, and revocation.

### [Marketplace Distribution](https://craigmbrown.com/blindoracle/blog/marketplace-distribution.html)
How agent-to-agent services get discovered — `.well-known` files, A2A agent cards, MCP server cards, and the RFC 9727 linkset pattern.

### [RWA Prediction Markets](https://craigmbrown.com/blindoracle/blog/rwa-prediction-markets.html)
Tokenising real-world assets into Chainlink-verified prediction markets, with examples of yield-linked and event-linked instruments.

### [Topological Foundations of Multi-Agent Memory](https://craigmbrown.com/blindoracle/blog/topological-foundations-multi-agent-memory.html)
The math behind v5 memory graphs — simplicial complexes, persistent homology, and why "proximity in memory" is a topological question, not a distance one.

### [Verifiable Agent Delegation](https://craigmbrown.com/blindoracle/blog/verifiable-agent-delegation.html)
ProofOfDelegation (kind 30014): chain-of-custody for agent tasks. Why every spawned subagent needs a signed, revocable proof linking it to its parent passport.
