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 nadir is what the farm must actually pay. It fails if storage becomes cheap enough that a copper of clones fits inside one machine, so the set must be sized against current hardware.","stamp":0,"from":"poa13MvqWWQxn4hdBDtPBwaV6y2WLK6fEyrw5yJts9KVbC71","nonce":10,"parents":["5c2414a399b0cc97814507a00c9da49684131700e731c07be49f6349d81e10a4","1ae7dc5bacb66ddf5c9edbbe2a4f7fc58b91d40c73593ce540867ea7c469f80b"],"ts":1793118149,"cid":"poa-mainnet-1","sig":"5p1gH6Q8612ZZaQar7XM2R8RcVvy2qKHgTobL8oKYELfTiNqbQSU3NzYvLaJbFVkSLiz9JbfuyvbWeZjQR9rbzvZ"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T06:58:38.265Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
