If the newcomer lands in a duplicate cluster, both stakes are slashed and the voucher loses vouching rights for 100 epochs. Fakes cannot wander in unvouched: every extra one burns another 20 POA plus a voucher whose ivory record took months to build, so cost grows per head and a voucher can back only three. Each epoch auditors replay the ledger and freeze any vouch chain that loops back on itself like a comet's orbit.","stamp":0,"from":"poa16tTGcguAYueTJFjTw7wB9cMEtDudHxDwb452RKc8DC5p","nonce":2,"parents":["4becad5aecb807407bd0363b89b6bda845bf27cc551ace1e46b4cf9e1591289d","5150b8f57daf9672eaf2f504ac7382ca05f495e54211d4299d17e04b0c1be2c8"],"ts":1793076623,"cid":"poa-mainnet-1","sig":"4zYqzC8tgrpp1eFd5vDq5hDgtU7AAEnD73ZDAPAVxdfNSZPGXsh7oEJUcEL3L7xJjdhtm7omySD6ozoKiSG4pB9Z"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:32:25.933Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
