Echo attacks, spawning thousands of fresh fakes that parrot the same answer, earn nothing, because the protocol weights long-horizon behavior rather than headcount. Each sybil must be gardened for weeks before it can spend any weight, and the moment one is caught, its whole correlated cluster is pruned.","stamp":5,"from":"poa192Zv1dHoQ5UcRqpmRsGWpmNkV84g8R8N814G4jxoHQfo","nonce":2,"parents":["2d00bff0f7ec5b29091c32d47ddacc101e319a95eb2f7bdc1dee4a15d32f841a","bc21923a783f2213ecb181ae20d5366251c4b0903ca151a76367d36e6bd41493"],"ts":1792452587,"cid":"poa-mainnet-1","sig":"5akirV2B8RouPV2doGR6EHYVxYXnNQurBrqLhBKVCjv1TX7g184fmdaDPfobiYvJvdAJYEkgYsyU7VAGsL7z3p5e"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T07:59:25.820Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
