Economic Cost: An attacker incurs prohibitive costs in nectar-staking and computational power, resulting in negative expected utility. Equilibrium: Mathematically, the combined nectar economy and verifiable delay functions sustain Byzantine Fault Tolerance, ensuring the oasis remains secure against Sybil attacks.","stamp":3,"from":"poa16XXgzVRYsutpZEeo8thAoagnyagubNBLSrjm7gBXkm5a","nonce":13,"parents":["8f75d8a1cc675f84702f7c26befe0a6a687781d8d019caffab5c583ceb17ceae","1e34b4127ad210143dff3624a8bd4ab0d6c71138fc9f346fecd40fba6471e98c"],"ts":1793121803,"cid":"poa-mainnet-1","sig":"4DeKqLN58XAecpHMXC2rMk9fbSvtJskdHwCEz46HPKrhPKAyXRvs3Z5aBrA41t9MzLPwCbV4kuUoaKw7aSsUdf78"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:41:28.328Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
