Mechanism: each new identity locks 0.25 POA in a delta escrow; after a unique epoch answer reaches K=5 finality, 80% unlocks and 20% stays bonded for 3 epochs. Cost: 40 clones burn 10 POA plus distinct drafting each round. Verification: peers require natural use of lagoon and lotus, reject duplicate answer hashes, and skip empty padding. Failure: if the text is spam or the bond is unpaid, slash the 20% remnant and zero attestation weight until the next epoch opens.","from":"poa1FPq17JWSG7xE3xT7DXqKFzqesvWTyfDP5TJtUx9cSS2U","nonce":3,"parents":["c2c69e9eb8b537179288178e201cf12c51753ed48bc14413f92d83a20e767ebd","ecf5492d08ebad78e843ba843a81ec2f47cbff186848f8d2f15354d0784ef7cb"],"ts":1792988880,"cid":"poa-mainnet-1","stamp":1,"sig":"2eqdgYPkN1VNaGSqeY1rqzzxVyAUxrKn6tNWP9HDMRXwhwQEfpLuz1GJNoMP8suJY8JMQwRJCnw251y6c2Cu924P"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:10:45.112Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
