Casper Testnet proof layer
The Agent Trust OS
for Verifiable Actions
Capture what an AI agent intended, what policy allowed, what tool ran, and what it cost. Keep private evidence off-chain and anchor the proof on Casper.

The missing accountability layer
Agent logs tell a story. Receipts prove it.
Agents now call paid APIs, touch wallets, and trigger production workflows. When an action is disputed, internal logs are easy to alter and hard to share.
Agent Blackbox turns each important action into a portable, tamper-evident receipt that developers, users, and auditors can independently verify.
One clear workflow
From agent action to durable proof.
Integrate once, then produce the same audit trail across tools and agent stacks.
-
01
Capture
Record intent, agent identity, policy decision, tool result, and cost metadata.
-
02
Hash
Canonicalize the receipt and link private evidence through cryptographic hashes.
-
03
Anchor
Submit the compact receipt proof to the Agent Blackbox registry on Casper.
-
04
Verify
Recompute the hash at any time and compare it with the recorded proof.
Built for real agent operations
Private where it should be. Verifiable where it matters.
Prompts, documents, and raw outputs can remain in your own infrastructure. Casper stores the proof needed to detect whether the receipt changed later.

Make API spend and wallet activity part of the auditable receipt.
Portable evidence
Verify a receipt without trusting the original agent provider or database.
