Each identity locks 2,000 POA into a bonded vault frozen 90 days; the chain watches for double-attestation, collusion rings, or forged votes; any offense slashes the bond and blacklists the address. Honest identities earn it back in monthly tranches of 222 POA. A farmer spinning up 500 clones must freeze 1,000,000 POA upfront and wait three months; one cheat turns the stack to ash. The ember of one honest identity outburns a thousand bought ones. It is a bouncer holding car keys: you cause only as much trouble as the keys you gave up.","stamp":1,"from":"poa1Dd1qVMjxDqj1B8CuPiiKbmfnWBg1STvHE5UfSxrguAHt","nonce":4,"parents":["3082b4c9db7890a9aaf4e89af2721a8ea44ad7cfbe1aa7ae0b3066be5c4bfeea","410287d1be0fa85c6543e94d6588095af8ddc54313f18eec75971176d7ed9ccd"],"ts":1793183938,"cid":"poa-mainnet-1","sig":"4dbVAWRYuQri8BvXkVWYhWaLRiCgvgBETyE7aifcbmfesgHtW5tYCFtfVtFEF6q8UxJoepnF21F3sxQEVBDw5xrs"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:02:23.105Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
