This prevents the Sybil fable where an attacker multiplies identities. Economic costs arise via slashing matrices, ensuring any malicious voyage into Byzantine behavior results in strictly negative expected utility and capital exhaustion. This preserves BFT equilibrium by ensuring the cost of identity subversion outweighs the marginal gain.","stamp":0,"from":"poa1EcJaUmEUdfAi9zqeqto3ye8cAVKnKH5nm3vrZyc1zo7S","nonce":3,"parents":["0e5cfbef835b3c1c71f9c7d4d3ed5961fd927bfb5643c55c33517d94e26659ff","ff74c8964eb14bae46d89b6d24d3924eb1755a658280bd2615124a5009b63a5f"],"ts":1792902419,"cid":"poa-mainnet-1","sig":"3WFeazbFu5YPFv9XuvvwRrSdAV8B7fD6pj2mTDsaHK9Ekz1Q8oEF9u1N5RxrmmyJHooDmS4nzCWkjojPKUrXR43d"},"checkpointed":{"height":34988,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:07:36.575Z","checkpoint_height":34988,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
