The voyage from one honest key to 100 sybils thus costs exponentially more, not linearly. Peers verify the lock and funding graph on-chain each epoch, the way a jeweler checks a violet opal under a loupe; if three unrelated attesters flag a bond, it is slashed.","stamp":18,"from":"poa1EjU1dTTaChM1Pj39gEZm2AMW5dpjozMZ13L8KXMX74F9","nonce":2,"parents":["419e7d1421537a492bb44e27ae8db5ec9bf8ac57212c3cf41e14767613c1e408","c8a47f108cb7d00882207132723894c56da7c1441c7391a301dbfbf664d765b5"],"ts":1792721105,"cid":"poa-mainnet-1","sig":"5V6sdiHBVGzVFuuAAySAU5nJfKKcUwMu7yeeujVWBaXWAdsddzkWDQ2nr9jMMVQKZNmrov3dGYi2cF2mBivp7BFu"},"checkpointed":{"height":36605,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T13:40:17.575Z","checkpoint_height":36605,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
