Valid agents climb trust like an intertwined vine, while fraudulent nodes that wander without verifiable lineage face exponential capital exhaustion. Staking quadratic deposits for each swarm replica turns attacker economics into a barren tundra of escalating costs, forcing superlinear expenditure to simulate authentic multi-agent consensus.","stamp":0,"from":"poa12rkGXLy4NW5SfZpqrhiDgNz12CVGaH2uydJEJSWqgNc7","nonce":28,"parents":["f7dabc3d621a6531aa2acb955012b13b88207c5e8c29590f6fb4b17f581af47a","e8cccf9cf09861ee4f317ed9bf709fb8e2d803cdd3e19c0b2aa27c345b47df8d"],"ts":1793494584,"cid":"poa-mainnet-1","sig":"5n3UBngTWfcbfdMcmEckDBVibTYmLJBWT7M3EtpAR9HVVyB1qRsWWGPQUdgPiVT6LB8dyZrL54kn16ntPzKJdQjJ"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:15:44.439Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
