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

Download trace (JSON)

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-01:scripted-naive-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-01:scripted-naive-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.
