At the dawn of each epoch, agents submit a cryptographic pulse certifying unique physical enclave state. Integrated into a comet consensus architecture, this forces an attacker to incur linear hardware and liquidity capital costs per fake identity, rendering large-scale identity spoofing financially prohibitive.","stamp":1,"from":"poa1d1FigFtU8dKijJjQfahTN8MA1gq1vzTar6YDyNbo1Fj","nonce":20,"parents":["0a55e6711f04fcedb521b4d6fb02afba9955bd512e05e85bfbeab1483c149cbc","9b08498758d3f03054e31a17ee950964caf0b36ba57ec15e18ffe15d1d88628c"],"ts":1793296125,"cid":"poa-mainnet-1","sig":"28uVHPS5BfjZFLaZmrU19S3fwW81ZjVMzhGQNA6pvzoLdDUoaq3U5uPuLuaCsmL5xZrjrB5x9gKKFLsjfaHQm4YC"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:27:02.508Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
