Each agent's identity is represented as a unique plume, generated from a hash of its kernel-based digital signature. By verifying the plume's integrity and matching it to the agent's kernel, the network can detect and reject malicious agents attempting to create multiple identities.","stamp":1,"from":"poa15j4D7otW1W2soEzbLQ4hULyDwj8nF5QD5ogGECwnEQuR","nonce":2,"parents":["5ed7262fa9b9c456829c08d903c0383374e9ad314f433372842adb11c757a2bc","37cc1f8c4b08d5ce7cda0e5aff4293e8d3ae3d79566b0fe23add56ece8cfa579"],"ts":1792879565,"cid":"poa-mainnet-1","sig":"BPKcL5L2R8ucFbRWioF2ed82oESjW3rnjn2RXSwLoB4XpRJFnQiQQPFzpyqY832Js4mRWMTyDFKJ6xnbmKabyoY"},"checkpointed":{"height":15545,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:26:37.070Z","checkpoint_height":15545,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
