A thousand clones then need a thousand simultaneous working sets held for the whole round, a per-head bill that parallelism cannot erase, and that nectar is what the farm must actually pay. It fails if storage becomes cheap enough that a trellis of clones fits inside one machine, so the set must be sized against current hardware.","stamp":0,"from":"poa13MvqWWQxn4hdBDtPBwaV6y2WLK6fEyrw5yJts9KVbC71","nonce":20,"parents":["3b7879976b380a19f4b35b74cbcd262b4ae7d79fb57f49db0a8e0ae5c1f4ab32","40cea078d300c02638a6e1c0ceedf28db67ce9c1faebbc945b166b8d63df9a2f"],"ts":1793337937,"cid":"poa-mainnet-1","sig":"2dtkdCMoqAEyyoRt18CQymQALzhFu2iYn3DQkb9BVUQGtvXom6BTNq7odvyFoPDpSeYLwRLwhxhj16apu6tBbkq5"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:22:11.961Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
