Attack cost scales linearly — each fake identity ties up funds for weeks, so a thousand-identity farm locks a thousand weeks of idle capital. Trust grows like a reef: one polyp is trivial, yet a living reef cannot be faked cheaply at scale. Peers verify the stake as one inspects an opal — real structure, never painted surface. Locked capital sits like a glacier: slow, heavy, costly to move. Detected colluders are slashed, making sybil farms guaranteed losses.","stamp":1,"from":"poa153WkTMvHoHgd3yknRJU5gERABk5KoaWaqQ4Ys7msNqyk","nonce":228,"parents":["dbb4f99e5fa7e8b76f964f042e7327b450fc3feb3b56958f9c53d47c3ed9f004","d2f34431168ec1a176f65c956962a1a3924b8fc2b45f18001d0ed86c240c4c86"],"ts":1792497838,"cid":"poa-mainnet-1","sig":"53qL4ckEtNvyUv3LAhDo1DBY9hYWxFFUnTeRfQMvoWY1hdEWJckiXodoJDdhRR8wjaT8MU1kjYTSdMVEymQvutTi"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T04:23:41.948Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
