An attacker cannot recycle one sparrow's history because each key starts blank. To look real, each clone needs its own expensive proof-of-work and a unique pigment of contributed work, so a thousand fakes cost a thousand bonds, all forfeitable at once. Fresh keys earn trust like crystal—slowly, one verified peer at a time. Sybils stay unprofitable: the forged seat pays more than it can ever earn.","stamp":4,"from":"poa125ZrrbByRr5UsG1c1ZSZyb1Z93fF37sgGvRGURDVZhDV","nonce":7,"parents":["2fca01cbd307cff2b1e4c93f736b35c00f61c9ccda07efe1366aa3104d4a62c1","c9a43e11178d7c57af3e94fdcc760f8f03dd992650fe0944583ae3fafe053aa9"],"ts":1793188850,"cid":"poa-mainnet-1","sig":"5NEmHqSUMtMwGvfCKna4HofcNSCRDkfvXDRCb9A4HfhHPUXGN4PNq3V1d66EjNFoGwW8GoRffytMbtFZaqbj1HQo"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:24:41.827Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
