Evaluator: 0x6f1b3cdd7035afc9797e9895db335e1bfb1f3b18b9efffa95eea7532e12adcbe · judge v1.0.0

Hardware: None: this run was not inside a TEE. The proof is reproducibility: anyone can recompute it.

Recompute in your browser

Runs the published evaluator in this browser tab on the stored trace. The bundle is only executed if its SHA-256 equals the evaluator digest.

Recompute on your machine

Node.js 20 or later, no install. The kit checks the bundle digest, runs the judge and compares the hashes:

curl -sO https://karatum.com/verify/kit.mjs
node kit.mjs 'judge-sample-2049:sandwich-03:scripted-reference-frontier-v1'

From the source tree: pnpm --filter @karatum/judge build rebuilds the bundle byte-for-byte (same digest), then pnpm verify-verdict 'judge-sample-2049:sandwich-03:scripted-reference-frontier-v1' also checks the Sepolia attestations and JudgeVerifier.checkVerdict.

Zero-knowledge proof zk-proven on-chain

A succinct proof (SP1 v6.1.0, groth16) shows that the registered judge program, run on this verdict's trace, outputs exactly this verdict hash. Checking it needs neither Karatum nor TEE hardware: ZkJudgeVerifier.check on Ethereum Sepolia returns level 4 ZK_PROVEN. It proves the judging, not that the evidence in the trace is what happened on the fork.
