Proof-of-action
Signed receipts attributable to one agent identity. Forgery needs the private key.
Zanii gives every AI agent a cryptographic identity and turns each action into a signed, hash-chained receipt — anchored to a public blockchain. Anyone can verify who did what, under whose authority. Without trusting us.
0 proofs recorded· 0 agents· 0 on-chain anchors// one line per tool — every call becomes a provable receipt import { ZaniiAgent } from '@zanii/sdk'; const zanii = new ZaniiAgent({ serverUrl, agentDid, agentPrivateKey, delegation, apiKey }); const sendEmail = zanii.wrapTool('email.send', realSendEmail); // sendEmail now works exactly as before — and is cryptographically recorded.
AI agents now touch real systems — calling tools, moving money, accessing customer data. But the only record is a log you could quietly edit. When an auditor, a customer, or a court asks “what did your agent actually do — and who authorized it?”, “trust our database” isn’t an answer. Zanii makes the answer cryptographic.
Every agent gets a cryptographic identity, delegated by its owner with scoped, expiring authority. An agent can never do more than the human behind it — and it’s provable.
Each action becomes an Ed25519-signed, hash-chained receipt in an append-only Merkle transparency log. Deleting, altering, or reordering any receipt is mathematically detectable.
The log’s fingerprint is periodically written to a public blockchain, so not even Zanii can rewrite history. Verify any proof with the open SDK — no trust in us required.
Signed receipts attributable to one agent identity. Forgery needs the private key.
Owner-signed, expiring authority with one-click revocation. Least privilege, provable.
Inclusion & consistency proofs (RFC 6962) — the log is provably append-only.
Tree heads anchored to Base, so history is immutable even to the operator.
Self-contained, offline-verifiable exports mapped to EU AI Act & SOC 2 needs.
Two agents co-sign one neutral proof. ERC-8004 compatible identities.
The protocol is open. Every proof is checkable offline with our SDK or your own code. The ledger’s fingerprint lives on a public blockchain. You never have to take our word for anything — that’s the point.
