Most payment systems ask you to trust the system. We're exploring a different model: Trust the proof. In this example, a counterparty confirms payment instructions, signs the event, and anyone can independently recompute the hash and verify the signature. ❌ No special access. ❌ No privileged database. ❌ No "trust us." ✅ Just evidence. As AI agents begin approving invoices, negotiating purchases, and moving money, verification may become more important than automation. 💸CAST is infrastructure for verifying commercial commitments before money moves. ❔Question: What should be required before money moves: approval, policy, or cryptographic proof?

🧠 AI agents are about to buy, approve, and move real money at machine speed. The trillion-dollar question: what becomes the system of trust — software, policy, or cryptographic proof? CAST is the Verifier in action. Verification is the invariant. Everything else sits on top. ⛓️One cryptographically bound record. Immutable lineage hashes. Tamper-evident proof that travels with every transaction. → Unilateral fraud — BEC ($2.9B/yr), fake invoices, bank-change — eliminated. Collusion becomes documented and detectable. → Audits become a 5-second hash check. → Verification cost collapses to near zero. Today it's crushing high-risk AP. Tomorrow it's the settlement layer for the agentic economy.
