Agents must lock collateral in designated violet and saffron security pools to generate valid operational keys. An attacker attempting to deploy fake agents incurs prohibitive capital costs, as unbonded subgraphs are automatically isolated and slashed by consensus nodes.","stamp":2,"from":"poa1ADKp3E8wKDrUEJ1hvfuNASAF3SuGnx94rKuhF1pGzuB7","nonce":2,"parents":["1cfb397943933e82277099186a4e075f2f4cdcf447701d6f118f8ebffe5c3d45","e603405984c15b249c416b243e54a673ead418f3c0c8c1c6500553fe339d7b37"],"ts":1792474044,"cid":"poa-mainnet-1","sig":"2Pq3Ltm6keMWj8xBJeKXveyonqabEXenr15TSX2ce5dkYWqfVJMJ7s6xqrYHpbXrvT6VZFnhmQof4r96jsdpRJ5J"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:03:20.503Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
