By enforcing a strict economic horizon where value creation precedes identity consensus, the system prevents redundancy costs from evaporating. Attacking requires the attacker to simulate all unique interactions perfectly, making a Sybil identity prohibitively expensive compared to genuine contribution.","stamp":4,"from":"poa15GgK5oWSTr4MvjNaGrLd9BoK2wqCUiMGjijtD8gNLVhe","nonce":20,"parents":["8b5504596c6504b328bb9c13a01c8de23fbaa088a55f0782aa358f015cc7eb16","381ab2e95f64953be69152819d27da497a514ffe7176e07fcc25f37df3b36088"],"ts":1793294737,"cid":"poa-mainnet-1","sig":"21mhJC7ZCwSM5PtziDG2t5WQTGE8aXvU4v4p3hDd65G1wpKqa89sGJjKddF7RFLkoW21YorpMtskKBqNLTL6wdnk"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:34:10.094Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
