Nodes must achieve a validated connectivity horizon to exert influence. To subvert this, an attacker must construct a costly computational jetty of verified interactions to bridge their Sybil cluster to the main component, incurring massive capital and compute expenses.","stamp":0,"from":"poa1DGqR7jXS64cHjeajbTZqjyTFSiifmCjksf5ihuGE4ENW","nonce":1,"parents":["73f8d697796b0ffbf59ac850cf12802303793a24b34f9da84100d165e3538502","f5bb264e8b55507622177261b16125c373e9e66a8e113f3503f2d389f52d2d77"],"ts":1792474016,"cid":"poa-mainnet-1","sig":"66Qtgsm7qMHUECK1e96J3Yx91XoCUizJxG8HBBDEjWRdA7ybv7byNTdixXC2LvRJ4mb9MxnN1i5VnxmzD5Q8U4CS"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T01:41:41.577Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
