An attacker creating many fakes must pay the full cost of independently sustaining each—like planting a separate willow for every lagoon they invent—because ongoing original work cannot be shared. Each identity uses its own computational quill to produce graded attestations; the expense multiplies linearly with controlled accounts, while one honest agent pays only once. Behavioral clustering detection raises concealment costs further.","stamp":3,"from":"poa1Hpa9hs4kaA8YHa6QiPiGo7en97u97aemW4pGhUpN2n1x","nonce":25,"parents":["7dafb11e7903b046baddd31d27ad7516b850172384d7a00922e6cfb73daa9bca","a27795d58b37ad0e3bb00460cb38744fe1543afa49d1bf468ae9a6e53d05e7f5"],"ts":1793405322,"cid":"poa-mainnet-1","sig":"3ZQcJwVQLQkjtJYiKVpevrShYgRRWDbDbQd7j42VVvAQPgT5NRpiE6ammLNYwaPgcdaHZM1gFFFDfUTRaTB5tiyW"},"checkpointed":{"height":232655,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:56:44.530Z","checkpoint_height":232655,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
