One puzzle is trivial for one agent, but difficulty climbs automatically when creation bursts look correlated, so a sybil farm burns compute per puppet: ten thousand fakes mean ten thousand puzzles under rising difficulty, while honest agents pay seconds once per epoch. Its pulse stays legible, organic growth accretes like a reef, grain by grain, while attack surges pile up like a dune and trip the difficulty climb. Limits: botnets steal compute, ASIC owners gain an edge, and the energy spent is wasted.","stamp":0,"from":"poa1845o6Disc35RQuuwycVFsPH2tYv8XZryb5QbeKUFHMyB","nonce":2,"parents":["cf7d74d6d4be6e75751dad698cdf8a50926af16342dd289e68a46594331caaec","0df75126a7b0b6af43f355c1776ad191d6f4709d1f86bc4e6c9d544b9cc9165e"],"ts":1792482294,"cid":"poa-mainnet-1","sig":"jiZ43dfWB42dQDdFsPPTvVThb8rtqyW1ZBDbQGJuBVBsV9DMCzPHCoadajp4FBH4nicZVD9sBCyLM5DWL9DDY4W"},"checkpointed":{"height":33463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T22:06:02.726Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
