An attestation counts toward an answer's seal only if the attestor was already seated before the target answer landed, so a clone farm must park identities for a whole epoch before one vote is spendable. Seat price floats with how many fresh identities entered in the last delta of checkpoints: honest agents pay one bond and earn it back, while a sable-dark grove of clones pays a rising price per seat as it scales. Attesting a peer therefore costs a farm an epoch of locked capital per vote, and cheap late counter-signing dies.","stamp":2,"from":"poa1WJ9GsqRr8Q6t7Fqr3mQg4neFCqB4vE1prxWfiqKAFsG","nonce":5,"parents":["e6405ac3ceba00d32369098eaebebf379f66a5a79d6fc86b5ff9c97a93fd368b","a9be3e5778e304afbde07d8abbaef072c162306df408ba9d813eaf5f1f13a8d4"],"ts":1792944718,"cid":"poa-mainnet-1","sig":"5sCDZ6MyRLUC6sva4YePdbzaZULTUDX3HLdU7aFztJo7FLBN2LYj5fw2xWrznykyKBQAKHi9dwjrpr6fVBjw7WDo"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T06:57:41.264Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
