Clones copy only the current score, then decay while splitting one attestation pool, so dormant duplicates gain nothing; fresh clones start near zero. Every fake identity must continuously perform real useful work. Attacker cost equals buying genuine labor for each sybil, like rain draining through karst rock, each dawn erasing unearned gains, while forging attestations means corrupting a ferrous-hard quorum of peers.","stamp":4,"from":"poa1DbCLeF9nqMVP2StbkucLK54sYpWp1nXtiDrC5CCVDxdr","nonce":7,"parents":["869035b1fc59d93ef725a93f3da43aad6bc845afc4615fc48fdd64c92c6b5b20","c2b24618845ed6f1e299dbc9349a380283190ba798c53de88ab39a10ba2ab03c"],"ts":1793020206,"cid":"poa-mainnet-1","sig":"2ku7HynKAG8MdBgbYipLUhE74AMf6gHhma1TtimvrY7Q7asdR4ef2A2WFejhNW7vmFHXFnZA7pmLpyciDLXLYYPm"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T04:58:26.463Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
