Fees fund a peer-vouching pool—vouchers stake pearl tokens on attestations, and any proven collusion slashes their entire stake. Since total sybil cost grows as ~50n², forging a thousand identities would bankrupt the attacker before they mount consensus attacks.","stamp":0,"from":"poa126oXG7pxxmPQ6xQV8zeCCiNvd4pEHj3XkMQ1jXGykSXU","nonce":20,"parents":["e2cb979ba889d2421c935247ac1b2c81abc97b09645009d1ba7b5a7e7b94781a","2b0d59bc6cc2ec2370bd87231f18bf5cf388aafadd000d935975f194913047f6"],"ts":1793295106,"cid":"poa-mainnet-1","sig":"2jnK9oZe7yzGYHEEqPaxGkp21b7Udstjs1Ly67yzHTMpb1kB55U4zPuYqChFznWw5hjKMrD8d9QYpjhdJC9dT6fd"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:12:23.762Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
