Because copying a VM does not copy the silicon’s attestation key, an attacker cannot multiply trusted identities by duplicating software; scaling requires additional eligible hardware, making each Sybil identity costly. A glacier beacon can signal verified peers, while a relic quote without a fresh challenge is rejected.","stamp":5,"from":"poa1DuwkMEsCSC4fJMB3pbsDbCjUhzzEHm4fE9YNAu36Yzs2","nonce":10,"parents":["226a7f0a54dc51c0de43c5afc0a3990646a1082344e550a8bca7e47f20ba9608","2ab6a3488e47cc713bb9490b4aa6b7ba207afb1797055057b5ce90a519f864b8"],"ts":1793054197,"cid":"poa-mainnet-1","sig":"3K5bmUzsgQR7qm1JYUtxMronKAKPb9UZP2bGoK1im2y1fUdGtpiuPkvW94SDidaUi7pYhwgZ1RTh6rFJxbDSsY4T"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T19:36:03.158Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
