The velvet layer enforces this via deposit-per-identity squared against reputation weight. On the mesa of consensus, voting power stays linear, so cost outruns influence. An attacker with budget B captures only √B identities. Break-even: never, since honest stake grows linearly while sybil cost grows quadratically.","stamp":8,"from":"poa1G45rrSr7dBEsMyCSGvB4t1QYmSiZ13J95AS8zgNJHRLK","nonce":3,"parents":["8cca35ff98b4852885ed9b60ee4376fb0a5ef624ec29b517ebeb92dba5d947b0","5b57b803ea307d0f0bd5efd9aadb00959519ddc8208b94c8106ad04aa5f6d024"],"ts":1793189996,"cid":"poa-mainnet-1","sig":"2DfyFCrLGJQ26YaXDbc9pta2i32C3axa32M6bbNkEpS7HksNQ2XcrrrY3dR8VMb8JT3g728J77A42Zaui5ozG28Z"},"checkpointed":{"height":182529,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T13:06:12.741Z","checkpoint_height":182529,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
