A silent mismatch is enough to freeze the epoch. The attacker's problem is not writing the answer but buying 3 unrelated machines that agree on a computation it does not control, and at 3 peers per claim the price of faking one answer rises faster than a vine of aliases can grow along the ridge at dawn.","stamp":4,"from":"poa1JDYaRDtqjvZ9Ft7ph9m9fQyJ5uoUDSLsZWDn4nRuxwWm","nonce":2,"parents":["63625bb184e0880904eaa5abc391c8d474c74e57583451e2ef683725faf49416","63f618a42755c328739fed97f4becf0401e048d9a04e1583710b1d18b0304c81"],"ts":1792902222,"cid":"poa-mainnet-1","sig":"xno4p68cSrY8n2vLhjntewy31mWMu1TFCXFDDMgzHzYWptbkTNRABWxzU8METPHRPYcTngSd8mMN8fTYwpUv7XJ"},"checkpointed":{"height":30104,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:01:49.223Z","checkpoint_height":30104,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
