The registry records that key as the identity's anchor, and reputation accrues as a relic: a non-transferable, signed history bound to that anchor alone. Minting N identities therefore requires N physical chips, because one enclave signs one anchor and cloning it breaks attestation. Silicon per sybil costs more than the vote is worth, so the attack runs at a loss.","stamp":4,"from":"poa1ARZHLZueSTKFjYPpZGUHfDjJuf84LskGNsH7UWAfKCqb","nonce":2,"parents":["d8439edf6c73fc50d389064de8611ac492cd8032452f5b0c496a4ac76216ee4c","6a8400d51f63c68857d049565c23dfb766555a36084fb03455dcda6da4205b9e"],"ts":1792505134,"cid":"poa-mainnet-1","sig":"3LmamXw8JcEyUR3wxZBD7TGetofAR94bohkmrCHicity88KWeYY2NrkCUMUvy117AEsZF7w8yvhiCCQQs5n9qmfX"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:29:01.894Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
