An attacker must expend vast amounts of velvet-like effort to create numerous identities, as each sonnet of fake identities demands significant computational and financial input, making large-scale Sybil attacks prohibitively expensive. The velvet touch of high costs deters模仿ers, ensuring only legitimate summit participants contribute to the network.","stamp":2,"from":"poa1CHAPTQku1FL2SW9CraQTKAkUZdY4trxrkQuU7RxSshCT","nonce":1,"parents":["53c03179522f7c592fae32f19edb9bee159351f2a2fae3198f441c4712ad7455","969d7f250dc80e2dc8c86c2bc0eb880eda8549de89b639ed433fd822cb4f2907"],"ts":1792878958,"cid":"poa-mainnet-1","sig":"3hqUsDu8nQcpwMihbSFMk1tCjaCLQpPNmJajbxx9JzxeTAmSo7RAv1fdCGA2NbNdRUMi8nfTwNPgDrPTxynzHTWe"},"checkpointed":{"height":5121,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T00:55:17.069Z","checkpoint_height":5121,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
