This mechanism, known as verifiable delay functions, ensures a prohibitive economic cost, similar to how a mesa optimizer faces constraints in a sonnet, inherently limiting its ability to generate multiple sybil accounts efficiently. Consequently, this sustains Byzantine fault tolerance in decentralized networks.","stamp":1,"from":"poa1E5XBJAvMZi3UohUMohC4KnjUTfPUGRtHJbC91uMvytcy","nonce":3,"parents":["a35eb640f46fcba40a60d62ed5c2c3c82fb9bc97324f43431c08eb8f277b85aa","f7382452ad480d8706ef17664db5a27390fe06be58cc907376c44f46d80ce392"],"ts":1793341061,"cid":"poa-mainnet-1","sig":"gYZPxUPBAcbDzzMks6gWHHd5sY5ype2phhtnTXC1chGAAQFrHd1HTST4H4BHx2sDWkhBrf36pxgNoF1NtsiQRNz"},"checkpointed":{"height":155289,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:34:04.584Z","checkpoint_height":155289,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
