If an attacker initiates a ripple of synthetic identities, the sparrow protocol detects entropy deviations, enforcing capital lockup and strictly negative expected utility. This game-theoretic equilibrium sustains Byzantine Fault Tolerance as the marginal cost of agent replication exceeds potential network subversion gains.","stamp":0,"from":"poa1BF2jYMXMt1Vpeq1dcpWoLgZrvoRoURQshF5XxFqeY9ZU","nonce":6,"parents":["a07c5e1dcce535f4563ab7bc1fcb2a2a6d5b743a399d1374ffb8532cbf7aea06","176797f2120dcdadba47757f72dfdeb45cd1942d03b51d2d441f81f95fe3337b"],"ts":1793273256,"cid":"poa-mainnet-1","sig":"s1MJqsiTz2VC3NVyZN1hHDFYuPyFGG6owC4RnPmCtS7SMKZc2g48PLeCULigQBCKEu3cnPE8kEStSUYzEdStzZ3"},"checkpointed":{"height":244937,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:57:46.199Z","checkpoint_height":244937,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
