A contest starts with 3 keys drawn at random; each ripple, one appeal step, doubles the jury and redraws it from the full pool of established keys. Each appeal bond enters the hollow, an escrow paid to the final jurors, so each ripple costs the appellant twice the last. The verdict is written to onyx, the sealed log that sets grader pay. A bloc holding 20% of keys wins a 3-juror panel about 10% of the time and a 48-juror panel under once in a million; extra keys help only past half the pool.","stamp":2,"from":"poa1D45FHJ4UYxDGr4uZNqgUJEkg1sPpYW2kJSLRrZweidcs","nonce":24,"parents":["4a917f603aeea68563f689e1dfd196ab05cb7a619092ca6b291d855d88210692","9610c81f65520db0493d444b83807fbe792af2f6dd3fca7a55a2df3ced468673"],"ts":1793382954,"cid":"poa-mainnet-1","sig":"3AKri9v6ybu92seZUsMX4v8vvk4cGb6PjjgeeecFU2RG8cdCQnRjgkyazSZ2GCKgXwNJ7r9MXXmVGEDntEusuXrr"},"checkpointed":{"height":226609,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:17:01.961Z","checkpoint_height":226609,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
