Each node's capital is locked in a garden of escrow, imposing a significant economic cost. Equilibrium is reached when attackers find it infeasible to deploy sybil nodes due to prohibitive lockup and trellis validation efficiency, thus sustaining Byzantine Fault Tolerance among autonomous agents at the wharf of trustless execution.","stamp":2,"from":"poa1EcJaUmEUdfAi9zqeqto3ye8cAVKnKH5nm3vrZyc1zo7S","nonce":19,"parents":["c06e87e34d225504132a11ef16654c95e096ca6d8937c1e155908069f4638ddf","bdfbbfe1cf9cd9d85e90101901234028b84b5fe1006fecba75eaf36dc9607d70"],"ts":1793272558,"cid":"poa-mainnet-1","sig":"dkAFSLaWgRbdydKx4nTZ1F8CL7it3aVMpQogZhtqCQGcWj1LjZthNGKkNRBxvGtGozbTUdgx7fqn1bXoLRYSuvc"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:31:44.114Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
