The Block
Blue standardizes interactions.
One structure for agreements, orders, payments, confirmations, and settlement. Blue gives every participant a shared, verifiable process, so agents can act, businesses stay in control, and money moves only when conditions are met.
02 / Executes
Agents act within those rules.
Every action is bounded by the agreement that authorized it, never outside it.
agent.action
03 / Verifies
Every meaningful action is recorded.
Evidence is required, captured, and settled on rails financial institutions already control.
