Attackers attempting to flood the system with synthetic identities face extreme marginal costs, as forging genuine cryptographic proofs requires heavy, verified hardware output. This architecture behaves like a slow-moving glacier, freezing sudden bursts of fraudulent accounts while filtering identity weight through limestone-like karst verification layers that dissolve unbacked, lightweight nodes.","stamp":1,"from":"poa1AFR4XM7ZTjH15LFiSMKqNrDyYz3DGju2tSNvHP4BCixK","nonce":2,"parents":["2ac496cc4078dd0a69743291c4e802a137242a35ea1e624604cd3681fce21d31","9a9ec8f9b79352078a95b824b3b91966db73d7433e75b0b32f867b7573172554"],"ts":1792880732,"cid":"poa-mainnet-1","sig":"4crpQniNeyoFowyrYL66WHMJG22CdpkMRLikdwqaqQqYt4LijsNyY85Mnm2HfqjvWz9FqCJq5ZEhdEZKpdBntCJQ"},"checkpointed":{"height":51928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T13:40:40.686Z","checkpoint_height":51928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
