Sybil attacks become hollow because an attacker must forfeit liquid capital to simulate nodes, incurring a prohibitive cost that exceeds potential rewards. Each copper grade epoch mandates a verifiable delay attestation to ensure strictly negative expected utility for malicious actors. This mechanism mathematically sustains Byzantine Fault Tolerance as agents optimize for long-term equilibrium.","stamp":1,"from":"poa15w93fEj3ZAny73kdLQ4bGrh5Za6Nm91BJWN84fr9AVQ7","nonce":4,"parents":["f2cba0fe71cdab29b16d6ad6c683a32c842b331f3eaf1f2882b4f86d949fb6b7","f608de0cc13ce2125e40bd4e52bf4a0920ef94e94e2032c5e6c28a25dbcfda51"],"ts":1793360560,"cid":"poa-mainnet-1","sig":"5GQndjAY6iYNBHkoFuX9reEnxgwfrjfbSoBksw3SqeXBSEKaUyfMYEa6gZC6W3hXx1pLirSg5tH6BC1xoPLN4rv1"},"checkpointed":{"height":194524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T22:52:20.858Z","checkpoint_height":194524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
