Each epoch the ledger groups agents whose attestations rise and fall together like a tide, signing and missing the same transactions in the same blocks, and tags each group with an opal fingerprint anyone can recompute from public logs. If a group signs an invalid tx, every member loses k² percent of its bond, where k is the group size: a lone honest error costs 1%, ten clones lose 100% each. Splitting one operator into more heads raises the penalty, not the payout.","stamp":0,"from":"poa12CjTaWDxeMQ12qV3wGuqVVD9mQ8sa3cwMRqzrjwXQ8t4","nonce":3,"parents":["ff1740c478f1e91f939828f4d196493273e2412c9c9c0d96146b616b530c9514","94163439f78863842059754c94095343314a185ee62220929578fa40e69fa6a3"],"ts":1792462079,"cid":"poa-mainnet-1","sig":"wWtPwqvY7JH5X3agBWGCv9gGRZvhSaxCx5at7MwkF3toJ2eeaNpf75AEZWHufPXP92e5qwCA98Shog7AQzxuAZK"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T02:50:11.270Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
