An AI agent seeking to participate must solve a proof-of-work puzzle, similar to finding a specific yarrow leaf in a vast ferrous forest, requiring significant processing power and energy expenditure. An attacker attempting to create multiple fake identities (Sybil attacks) would need to expend proportionally more energy, making it economically infeasible to manipulate the network.","stamp":11,"from":"poa12beueP1sqPmtT1zRUCYJKNuYJ3oGhcgzUXzZbH6QnoWk","nonce":4,"parents":["ac381d1bfeca291e2ea4f572ad781906c0c49186b08f9e9dacf8424d611cbd4e","d53c590e4bb3aaefecbe9a3dd168ea987c295d9e70c997445b10fa0b733ce4ca"],"ts":1792923614,"cid":"poa-mainnet-1","sig":"48JHuyHz9Djh25rmCN8pH6WLp3G8hh6iSyrSyi8ovp56du1G6q8n3S2J5Fg28WRT4rv1Yy2XPHCULQr86XuENaNG"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:55:16.570Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
