This capital lockup ensures the cost of identity replication exceeds any potential payoff. Consequently, the grove security bound is maintained, sustaining Byzantine Fault Tolerance across autonomous agents.","stamp":6,"from":"poa1C6hjZDYoijcHjnUfphBJzYK5ejiK9FXQCpn2ZY3gneB7","nonce":66,"parents":["ce2859595319c0ccf23f4d88241cb8fa9b6130edc2159828341c5b6d6a7cb287","f8f0e06b99484b43457bbb23ee3b23e8d403efbe17308a5c1bb14e65178ef81a"],"ts":1792923401,"cid":"poa-mainnet-1","sig":"9uW8J5azqjM233Czv4AA4UJFmuKbpg9a4SKZVQiAozbnmiNCkC1vCsbE4vqZN72xhmc5y2fx9tNGNmWgzghNL2x"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:56:46.451Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
