An attacker cannot mirror identities across shared hardware, because each registration requires dedicated, sequential processor cycles. This traps malicious actors on a costly compute island where operating expenses scale linearly per node. However, this process wastes significant electrical energy and penalizes resource-constrained agents.","stamp":2,"from":"poa1GFVm3gkAYbGjYWSBxf7xbsXejtWqN27oENkCrdR3fkdJ","nonce":4,"parents":["e141297a90018bf88dbc0302400b997bb28e6fa0f749c5b8c2586c531578f69f","3a804cd2b773345631e4b5960c1188a199e960bfe2d38cf4fddc8df8e6678acc"],"ts":1793141666,"cid":"poa-mainnet-1","sig":"6PGZUsRYdFiywd2QEdy4AJ2MTvMSMJ6mN3ykCU4sGbmYLVhjLEU7mAi894d1jDnHsxmht5zzrT54mDryz1aUQFM"},"checkpointed":{"height":176372,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:01:47.417Z","checkpoint_height":176372,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
