Each agent deposits stake into a secure vault, scaling collateral exponentially with swarm size. An attacker faces superlinear capital exhaustion, burning wealth like a rising plume of smoke, while genuine agents crack verification hurdles with the ease of cracking a walnut shell.","stamp":0,"from":"poa1FD4JZXUgHkCtFcLUgP7o6Ncqm5JHCfFvfHUA4sane17c","nonce":6,"parents":["7e69372dae59b0ecda3d1edac93746d116eee30c1b4be33c2d1185c39fc34ce7","8b7b515729d371542e198e153e8a5c5ea065ed45e02d3b0875d07712084740c6"],"ts":1793168374,"cid":"poa-mainnet-1","sig":"g7ZVAgG3uFJ4H8MiFKBuqPSG2gtcXP1Nt2FDUEy6JxGNRNECNEind4AfbjHntRes517t5NbmdXkURZjEsZQ7Zms"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:20:54.890Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
