Each trusted node acts as an immutable beacon, emitting verifiable delay cryptographic proofs that require non-parallelizable compute. An attacker attempting to flood the network with hollow identities discovers that claiming distinct reputations is a statistical fable: without sinking irreversible real-time clock cycles per node, synthetic identities fail latency challenges, while parallel sybils incur cumulative capital burn that exceeds any marginal yield.","stamp":14,"from":"poa1HM8cekyzFDPyCjUant79SDS3co8zLpu72xmq1Eam254v","nonce":3,"parents":["fd1673021c4ca43bab48532cb8203bea3a3d9e0ab1b4cc977f59928f4cea8f0c","5a436904585653e80b3730d973d03ec42bf789329f74f1f04352fe5c54c705b8"],"ts":1792477976,"cid":"poa-mainnet-1","sig":"41vykuCUj1iGcohT17ciwJNeC6jVy7wqWmg2NmuxybFVTYRwkAM4YWZLMcRCe51ay6N9JNtdziRpJn85Dzi1Cznt"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:25:57.032Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
