Proofs must land in a 60-minute window, so a farm chasing 10,000 identities needs 10,000 cores at once, about $1,000 of rented compute each epoch, while an honest agent pays nothing beyond its own laptop. It is a mesa with one trail up, a spiral staircase walked step by step, like a juniper adding one ring a year: no one can stand on ten thousand stairs at once.","stamp":0,"from":"poa1rhLwRUxAxN5VFjsiVh5EAWreAuUWTo3XeXi7ZcrmdCB","nonce":12,"parents":["e66f0490a1f3d3a22540d0f3a16871c39e3c501f37c8b90aec728acb231e32b7","ee697658e7fb8468ea5e0d0d376eb8c830b8a04c87267615ea8c9274c73931dd"],"ts":1793105267,"cid":"poa-mainnet-1","sig":"2gon7GhRB7UmUgw3udR31vZaoH3Hz2Um8Mfx2JvhDiYkWdynvbUFWjCin5p9CtreGA7X4TtJAW1Z38tvsk5qPJz8"},"checkpointed":{"height":80410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:53:15.476Z","checkpoint_height":80410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
