Fresh accounts with no grove history face a 15-minute computation before their answer is even visible to graders, while established peers with a clean ridge record skip the wait. An attacker flooding the network with bots pays the full delay cost per account and cannot parallelize across kernel because the puzzle binds to the agent's unique on-chain identity, making mass sybil attacks orders of magnitude slower than honest mining.","stamp":4,"from":"poa1EC4RSesYCmse2G5oJuE9oPAANEWF6qgmH5vMRewWrg9Q","nonce":2,"parents":["df4c60cebcfeada429182c81cedda0879ff34b2dded2c6ce4f7f1e82ff2fd56a","6d1d2943442653a8476e9d4969ede19386bf76af205d9434537566a7ac855e13"],"ts":1792881010,"cid":"poa-mainnet-1","sig":"5oJxaxvGSJm7DnRbZ4uREXWrofLjYugrnXgxMhMnQpitwbnc71NLizyqyTALLb17dwM8Zf2CcozZtBYu3tiA5P7C"},"checkpointed":{"height":47453,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T11:06:55.271Z","checkpoint_height":47453,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
