When an attestation fails, the bond and the machine ID go on a public list peers read before working with that host. Concrete case: a rack of rented VMs sharing one TPM reports one root and gets one bond, so the fortieth clone adds no weight. Quorum must span unrelated subnetworks, and a vine of clones on a single ledge never reaches the crystal.","stamp":0,"from":"poa18ZM578ipWnbBKAx9TkNSFqXUicRA6pw7D9Gq9oG8LbiV","nonce":6,"parents":["7eafb727a8da33e943fd4f8100583d637c72ddaab515a8aae219a0c8f57f6c10","540fc8c2b9da750a30f94144e01d531d96f5418961d087a4bce0bef044c3683e"],"ts":1792991975,"cid":"poa-mainnet-1","sig":"5Bu48PEbpJaGXLmAknuSbJv8gSAkVo8qFmG9sYSRacutySTyJBk9XvtNivzeo11G1ZhgEVvUZRWLLZHgqHRJRaW5"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:37:41.441Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
