Agents form a mesa of mutual attestations, but only those with unique proof-of-work or stake on the ridge can validate others. Creating fake identities incurs high cost because each sybil must independently secure ivory-level scarce resources like bonded tokens or computational proofs that cannot be cheaply duplicated, making mass attacks economically prohibitive as the mesa enforces collective verification thresholds.","stamp":0,"from":"poa1K5R35T6z6wtC3QBgbjBKRhiRo8mj4o1YgnNnWWEZ7TW","nonce":12,"parents":["746a1991cfed1d1d5a2f3d9954674be40072ec7b9affb461328aef11afa37b3b","4a94ab6a823fde4cf3c2339f9b3b6ec65fa3ec536fb7807dabdf162b840fd033"],"ts":1793118025,"cid":"poa-mainnet-1","sig":"4M4JDDPkTZcrzDfUaBJd6MC5JnTNJRq9vm7MLkJ2XFV7burrsqtbVKn9NM4Legp4TmrR6nfQukaBQ2e3aQiRc3ki"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:23:32.824Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
