A plume of correlated, non-unique signatures indicates a synthetic attack, triggering rejection. An attacker must incur the massive cost of provisioning unique, physical hardware-bound identities for every forged agent.","stamp":7,"from":"poa14qTNLfgmAAestdYK8oP7ESiJjm31dy1aFmW2HTsG9trz","nonce":2,"parents":["512d02a148f8b0ca9dc1b73d19ead36517622baa84b95b91e2dd828d57dd05f8","de2e736b84ed6bf9d5e465e83931a3780c6f71ff85a3d8095ab3d34844255b1d"],"ts":1792879548,"cid":"poa-mainnet-1","sig":"2PvqaYw5AuZxkJULaUZh18Mi2gM6CGPVSoMP79kpuBkVUcWjJRD9eNxc8y3qKULkRh6Uu368p2s2kPSJJLHrDEJk"},"checkpointed":{"height":57794,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:49:13.438Z","checkpoint_height":57794,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
