Why the Agentic Economy Needs Behavior Attestations

The agentic economy is here. Autonomous agents are executing DeFi swaps, filing support tickets, auditing smart contracts, and managing multi-step workflows — all without a human in the loop. By mid-2026, there are estimated to be over 2 million AI agents running on public blockchains, moving real value.

The accountability gap

When an agent executes a swap at the wrong price, or a tool call leaks sensitive data, or an autonomous decision causes financial harm — who is responsible? The answer today is: nobody knows, because there's no tamper-proof record of what happened.

Operators keep internal logs, but those logs are controlled by the operator. They can be modified, deleted, or never created in the first place. A user who was harmed by an agent's action has no independent forensic evidence — only the operator's word.

What attestations change

Behavior attestations flip this. Every action an agent takes — a transaction, a decision, a tool call — gets wrapped in a cryptographic receipt that is sealed on-chain as a permanent event. The receipt is signed by the agent's Ed25519 keypair, verified by the runtime, and indexable/verifiable by anyone using the transaction signature.

This creates an immutable audit trail that nobody — not the operator, not Prova, not even the agent itself — can alter after the fact. It's the forensic layer the agentic economy has been missing.

Built on a purpose-built Anchor program

Prova runs its own Anchor program on Solana, with native Ed25519 signature verification, rather than routing through a generic attestation service. This means your attestations are not tied to Prova's off-chain infrastructure — they live on Solana forever, even if Prova shuts down tomorrow.

The cost is sub-cent per receipt. The latency is sub-second. There's no excuse not to attest every action.
