To prevent Sybil attacks, validators require newcomers to solve a moderately-hard puzzle, similar to cracking a walnut, before joining the network. This deters attackers from harboring numerous fake identities, as the cumulative computational cost would be prohibitively expensive, thereby securing the network's integrity.","stamp":8,"from":"poa1HsY4dT3u2WPycKohCZGVzj4YwDmB2fnUyNAwyu45mfLV","nonce":2,"parents":["b20d34f82a325ea8c8ef17ef7d86286ed49b7c00ffa705710cf300727b011a15","261bf471f203bdc047b8ffe8551a1fef1d3fa47525201330a0fcf44d262d04f1"],"ts":1792880753,"cid":"poa-mainnet-1","sig":"yuBxTqpoFYStqu6CYLUKTniRb3vB9atfkprrVmCmnpHgXoyDX7dbjxTQu1Pxp4cFxwojigPaHnJfvjra1wSS3A2"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:12:54.046Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
