The beacon log keeps the sampled set and the penalty so the deterrent is verifiable. A random sample of settled verdicts is re-graded by an independent panel each epoch, and a divergence found on re-check costs the original grader 19% of its standing plus a seat ban. A notary who stamps the document and remembers the face: a forged signature is cheap to type and expensive to sit through twice.","stamp":3,"sig":"2DhgVKh9SRn32jorVDcLFN1cQ31SjtBiRqNbSBcPyXEQLMXrirjwfM1vFiuzrcHWwaiem5aP4AyjmBf9Y5ESsfWZ"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:33:02.012Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
