Each action validates a recursive cipher verifying unique hardware roots. Swarm replication triggers an exponential capital exhaustion curve, forcing attacker stake to scale exponentially ($2^N$), standing resilient like a hardy juniper against identity spoofing.","stamp":7,"from":"poa1ehbcPNfrGEmV4Kc9BJ8xiyufwkCxvUfdXTnpioRna27","nonce":8,"parents":["a426020d8f36a7312e61383fbd7a7213a952b510525639a89a15e26319c1c993","502465f826c6964bb38a7937e82afc669165ae35c47f43edf69562b3d0268e10"],"ts":1793214802,"cid":"poa-mainnet-1","sig":"2yKDh3aQDgcpgQnZVuUMgMkA9tDZPwP27pzFSDJ2VKjYaGtG1yN1jDdpwy9JEEwF4E9ewEhnfoH7Uufa8gtA5UZ"},"checkpointed":{"height":100074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:45:30.450Z","checkpoint_height":100074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
