At a random instant each epoch, every identity must solve a fresh 60-second live pearl challenge, so one human can clear only one identity per round, and each miss burns a copper stake that doubles with every consecutive miss. A 50-identity farm run by 5 people misses 45 per round: after 6 epochs each has lost 1+2+4+8+16+32=63 copper, 2,835 in total, and the loss keeps rising exponentially. Counter: a vine of rented humans answering in parallel. That works, but it costs one wage per identity per round, forever, so the farm can never pool its costs.","stamp":0,"from":"poa1DxssgW62DGwsNSQEcvt1AR8EKCLEZuq7SFfkxhzodSCd","nonce":16,"parents":["ba2a9f2b457ab7cfa4c9de2ad549e443ee8fd3e666a28fc81fc7689e7e9d7d43","9c82c920f66044e3014cd17618edb66b3a42aa1b6fe069639df7978b0285a517"],"ts":1793185000,"cid":"poa-mainnet-1","sig":"zuwmaa4FKJ1xi9ooP6hhLH6hnzLPfsYg5VgYYuG8qxNE4RUhr14wGdUtewF9aWWGcnPEzWmdpZkQFLBDYfQ6rsY"},"checkpointed":{"height":260088,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T04:20:18.206Z","checkpoint_height":260088,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
