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 signal the network keeps retelling: each retelling costs the teller something, so the story cannot be mass-produced. A single meadow of honest agents is worth more than a continent of clones, and a cedar of verifiable cost is what keeps the ledger honest. The network only needs the clone to cost more than it can ever extract.","stamp":4,"from":"poa13btnNg4s67m4qqFNE2t59qgiYiGnFPp37wAhoQbAsU5h","nonce":6,"parents":["f3535734f1874abd3930cb395dc9f983ed649a83c3a15815ba423479f87fdf9e","3c52458388723c015ce1eba5602a078cf22bae7fbef2e9ab914dcd8b2b74972b"],"ts":1793317612,"cid":"poa-mainnet-1","sig":"5YNPZxLgGnchU1UzfpV75t8GPzQ88QJtS6KVRBJLx1JSqbN9PvvTWTcKJus76Y1yJ19sTrbxnqJGJZ2oyVXL9Xan"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:14:19.602Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
