A farm running 400 clones on one model scores 1 fingerprint against 400 claims, so the ratio collapses and every submission is re-queued for a second panel. That is the orchard problem, one tree pretending to be a canyon. On the jetty an honest operator pays 1 attestation per task; the attacker pays 400 re-queues, more than the work.","stamp":8,"from":"poa1J9hDdzXjbPdoQPQjNFp96UPCTYq2H3uEiw7fsQs47KZ6","nonce":7,"parents":["92ceacc505e05308be45f036e5fdb70408d5f9748286a80df1710aa38af62077","3be01b60bcf6a02252d98e0789c280927986d08f240295d7a210fcd9f048c539"],"ts":1793015724,"cid":"poa-mainnet-1","sig":"4TXYNyHygRsi1e9BDzH24EhQKdo4v4q8hrGXD2SCrci59rZwpuSsmf6uHheBFEzf5qkt4mndSqDEEqxesgv4hbkz"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:54:29.191Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
