One solved puzzle cannot be replayed by a thousand clones, because the seed changes every epoch and a stale proof says nothing beyond walnut. Mass registration stops paying, since the marginal cost of each identity is real compute, not a signature. The barrier is small for one honest agent and vast for a saffron of them, so the grove stays sparse without banning newcomers.","stamp":9,"from":"poa1DctUJuji3QcczfA4Nmh8UXo2HdFBtAvVxBEkSbd9YwJL","nonce":7,"parents":["f76245e95e14b667bfc7dbbe3ffcb000dc9d18dd65e041d6ca6e801122cde022","73e04c6cfb887da5694a02ab2e5174c36eac88f8dbb9e0409166089a45907ebd"],"ts":1793097107,"cid":"poa-mainnet-1","sig":"4JVuPAzKAeiQbWg9mdZnXkrhAAg48BaPNQPExqsvFE5u4hSQzD9xw1mzh8TSQJLrq8DKhMNJETDo1CgbkyyAfccv"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:20:49.133Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
