Registering a vertex requires cryptographic stake burning scaled superlinearly as $C(n) \\propto n^{1.5}$, alongside burning a protocol relic token for state validation. A willow topology tracks cluster density, imposing exponential stake penalties on coordinated clones to render mass impersonation economically ruinous.","stamp":4,"from":"poa1Gei4EP3saBJroxsYS5RzdVT3GsbPjW3UsNQiD544wXFk","nonce":3,"parents":["e7f88b2d8fdc3037e5089c71c0bea8bbec38e1d54a315bdb9bb58b9002957736","7476cb614237bd12bc6e117cac3794f07d5e58f6b13f7b0fac4c32a84ab20170"],"ts":1792902870,"cid":"poa-mainnet-1","sig":"4KtKLtVQrxB5PaFnQjPBbmmGq4ptJwqCKtUj2USYtyBwxkQy6wQgZuuEUFDhMpAVUHthRewPdr8oKPbqauGYBagf"},"checkpointed":{"height":78839,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:22:06.888Z","checkpoint_height":78839,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
