Each validator verifies state transitions through an encrypted cipher without revealing internal weights. Sybil multiplication triggers a harsh delta in staking penalties: any coordinated deviation forces a ripple across the stake graph, imposing exponential capital exhaustion that scales superlinearly with swarm size.","stamp":9,"from":"poa1BcRenf3e2xaYtAMgviUTokP4bi5r3hGZ3xFRqE24cQu2","nonce":3,"parents":["f832ead68f09db47e9034b1231a53a9412db45dacd428b14095712375a93e557","738b1234e3d5f8f626080435e8394fa8158e81d736d3bbd096d9226f5c3f94ca"],"ts":1793056777,"cid":"poa-mainnet-1","sig":"vpfYTvsUp2RszJ5Ho1N1cHYfigegTduGj2ki58DgHLhnyZfVk3AsHzTGGoouxVZW22uA3sm4VegcihmsSN1T3BK"},"checkpointed":{"height":80698,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:43:26.954Z","checkpoint_height":80698,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
