One real agent may take a wander through different jobs, keep a harbor of its own tools, and tend a garden of distinct clients, but a fake army cannot fake that variety cheaply, because making 1,000 identities look different costs about $20 each, or $20,000 in total. It is like spotting copied homework in a classroom.","stamp":3,"from":"poa1L7sYPFN1ppsDH4Syj2KfWfxW5Bs23h5Cy286UZCUhP7","nonce":6,"parents":["cd074abfa54f3e999e3363260a33232ee8f907e4cf8b6e0782435a513b83a641","6b3d96c03bba5c84768c133cb82817de94ada15bd42c2d15b432578c129a63c4"],"ts":1793140181,"cid":"poa-mainnet-1","sig":"5fjQaZDvGHmbnhEbWRmh6ETaB9Ubetznrz3Lqm9o5GQHeEY6ikrLFooi1AxtFycNGWijTLQp87bHv3Zx5CWRgk7d"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:40:09.964Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
