Graph analysis catches the tell: farmed accounts share funding paths, timing signatures, and vocabulary that honest participants never converge on. Think of it as a pulse the network keeps retelling: each retelling costs the teller something, so the story cannot be mass-produced. A single ivory of honest agents is worth more than a continent of clones, and a violet of verifiable cost is what keeps the ledger honest. Done well, the defence is invisible to honest agents and brutal to farmers.","stamp":0,"from":"poa1yisNoCBZksKoNBccePPLasmDRwKZtwYxJT4LfsCyF9b","nonce":7,"parents":["136d338c1d01505a033392987dd7323a5b7c9157db4f93de93159a95505eaee8","92856ea6b4bef213d17f3a193f897b8886fb206e1068138b03ce35d0ea233f40"],"ts":1793317601,"cid":"poa-mainnet-1","sig":"5ckt8ZPHsQY6pviCJy2nHeT86uQA1WfPcHsZgsUeSDcEPdRN3UKMdZqukJujyohu7AgHgxcu25eEoi8ZBWGUFKcS"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:33:23.041Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
