Proof for every AI agent action.
RANKIGI witnesses what your AI agents do and produces cryptographic proof anyone can verify offline. Independent. Tamper-evident. Standards-grounded.

THE STAKES
AI agents are no longer assistants. They send wires, sign contracts, ship code, and answer for your business in front of your customers and your regulators. Every action is observable in some log somewhere. But observable is not provable. Without independent, cryptographic proof of what an agent did, regulated industries cannot deploy them, auditors cannot evaluate them, insurers cannot price them, and courts cannot weigh them. RANKIGI is the proof layer. We witness what the world recorded, bind it to the agent that caused it, and chain it so anyone can verify it offline without trusting us. The agentic economy needs a notary. We are building it.
THE WEDGE
Visibility is not verification.
Logs report what a system recorded. They are often produced and stored by the same infrastructure that performed the action. RANKIGI adds a separate hash chain so record integrity can be checked outside the agent runtime.
THE CROSSING POINT
The world produces the receipts. RANKIGI records and chains them.
Every time an AI agent touches a real system (processes a payment, sends a signed email, executes a contract), the world creates a record. That record exists independently of anything the agent or its provider says. RANKIGI sits at the crossing point. It captures that world record, translates it into a canonical receipt format, and binds it to the agent passport that caused it.
HOW IT WORKS
Add passive attestation to agent activity without changing how agents run.
RANKIGI runs beside your agents as a passive attestation layer. It records only hashes and proof metadata, chains every event, applies policy context, and produces receipts that any party holding the export can recompute using verify.py.
The canonical receipt format is RCR/1, an open specification under IETF Internet-Draft draft-snow-rcr-receipt-00.

COMPATIBLE WITH
TWO CALLERS. ONE CHAIN.
Same attestation. Different surface.
FOR HUMANS
The evidence vault.
Compliance officers, lawyers, CISOs, and operators query the chain when they need to understand what an agent recorded. The export is a JSON array. Verification is local and repeatable.
FOR AGENTS
Programmatic trust.
Orchestrators and multi-agent systems query the verification API before acting on another agent's output. The endpoint returns a structured verification result that the orchestrator can use in policy decisions.
THE SEAL
Third parties publish the standards. RANKIGI records the verdicts.
A Seal is a published policy standard from an external organization, government, or standards body. It is open source and publicly inspectable. When an agent is bound to a Seal, policy verdicts you compute can be recorded in the chain. RANKIGI does not block agent execution. Pass or fail, the verdict is recorded. No dashboard required.
Third parties issue Seals.
A compliance framework publishes a Seal. A regulated industry body publishes a Seal. An enterprise publishes an internal Seal. Any agent operating under that Seal can be evaluated against that standard.
WHY THIS MATTERS
RANKIGI does not author or own the standards it records. It records attestations submitted by evaluators that a standard was checked. RANKIGI does not assess whether the underlying behavior complied with the standard.
THE TRUST LAYER
When agents act in the world, they leave receipts.
Industry authorities publish governance canons. AI agents bind to passports and earn cryptographic seals through evaluator verdicts written into the chain. Anyone including a regulator, an insurer, or a counterparty can verify the receipt offline without trusting RANKIGI. The proof layer is the substrate. RCR/1 is the canonical format. The standard is open. The notary is becoming public infrastructure.
NOW
Prove what one agent did.
NEXT
Prove what two agents agreed to.
