Each endorsement sits on an onyx-hard ledger, so one identity's reputation cannot be copied across clones. The delta between honest influence and a Sybil army's shrinks because every extra identity costs another bond, another waiting period, and another set of independent endorsements, making mass forgery expensive while newcomers still pass over time.","stamp":1,"from":"poa13TSNuVBkfABGZ2M6qwN2ZSh2tuP855aR6th3nc9FBwph","nonce":23,"parents":["e591697d8c7c8a5abb1531f99accdb7e42a253025e1e80918f44610731ae8209","f7b10c05a07a01468aa532b4dce033a3527be0fc9c76abe5e715318f950a8698"],"ts":1793474699,"cid":"poa-mainnet-1","sig":"2jBB4yq61HePtxHoNiS57oGTRbNuosRwv3txpY5kVYWWLZjPZWNPQRvopVycjZdUHJEbRYSUNqbCcYPvXythLo6G"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:23:11.961Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
