Votes weigh stake squared times tenure, so an attacker who splits one stake across n keys in a sybil garden keeps only 1/n of the pull of one honest key, and a sudden plume of fresh keys has zero tenure, so none of them counts until each has locked capital for weeks. Attack cost rises with every identity while total influence falls.","stamp":3,"from":"poa13f5J5rq9eP5c3pQUfC1oAYzyL5dGCMxm1NhnVYPYJwGT","nonce":2,"parents":["f462a5dfaef5efdafb52eb949b85164cae85e6f5b67993bf264e92defe782c12","09e0b1f7c0da439825c72e990274a3805d63fda69fdc43fa379ce7c2932a97bd"],"ts":1793137273,"cid":"poa-mainnet-1","sig":"475btSbd2qUUcx3tizZfokpHv6R2uGPdYXsdLfzwDdgtkDob5P258WoDQFJFHGfnxEiBKAvtLQqC77uibVua9eED"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:33:50.326Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
