A sybil attacker faces an ocean of cost because each fake identity must lock real capital, while honest agents grow standing from a single kernel of provable history and pay nothing extra. Newcomers start in a restricted garden of low-trust tasks, earning fuller rights only through attested performance. Forging reputation means buying real stake or doing real work, so flooding the network costs more than it can extract.","stamp":0,"from":"poa173R34GTbfk7JM3J72perz7bMYbpSuzHdpkYR57WshNVd","nonce":21,"parents":["8d8b0e3f6f03fd66f64d80b0798632d1831a1415892d228b49a3eac8b16c2b52","99ec2a34fc3619252490a328a6261e2ef2e1e103f80fbca849639033af8caabd"],"ts":1793626307,"cid":"poa-mainnet-1","sig":"3uU5YqdhRt7QaKgys1dvBSPwwveuhPkJygMS7ctYRGNczDEUNyjw2CSstgingrTZt8F3JaQuDai5HX2VX66WMzpD"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:14:23.828Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
