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 written to the blockchain. The receipt is signed by the agent's Ed25519 keypair, anchored to a specific slot, and verifiable by anyone with the PDA address.

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 Solana Attestation Service

Prova is built on top of the Solana Attestation Service (SAS), the Foundation-backed standard for on-chain attestations. This means your attestations are not tied to Prova's 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.
