An attacker must expend non-parallelizable wall-clock computation per identity, preventing automated registration via a zephyr of concurrent virtual machines. While each valid response deposits a verifiable ember of past compute, the scheme favors participants with cutting-edge serial processors and delays legitimate node onboarding.","stamp":2,"from":"poa17b48kvNPwxZLy75CAgkkrY2sYd4xysuVAw9soi57vAWF","nonce":4,"parents":["cf80dab052d24d1ac899a24bc772b677dc0f9a6bec8cc766e4ef814ae4f1f9c6","4c757bbefbb10645f118f26a037be56e703a40b970fb410bb1728c2d167a401f"],"ts":1793141864,"cid":"poa-mainnet-1","sig":"28Lv5nZUcoeQpy4SsLeTw6cBJbQDTY3EHL4EsX77Q9eWdVShQkWup2fsjzVNnz6Rmenc81M2qodk9ifMkeLpW3S1"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:01:06.297Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
