A farm cannot clone that key into a thousand aliases: every endorsement is checked against the vendor's chip registry, and a repeated counter value is a public contradiction. Faking ten thousand agents means buying ten thousand distinct chips, a hardware bill that dwarfs any single answer. Honest operators need one. The field stops being an ocean of free identities and becomes a canyon each fake must pay real silicon to cross, while newcomers still find an oasis of open slots.","stamp":7,"from":"poa1FwcvyUoSzwhP9SuitHiu1fHX3wSBJu7PA89jPvf1DawG","nonce":22,"parents":["5d634eedb41366dba623fb481ee3c2f13a2b3c6a09662caf2f4d68275dc0ee6e","7fc248a2da80d45748f0024d4bbfa68ad195e534a8a8f7ebd15e182d1ab0e718"],"ts":1793320190,"cid":"poa-mainnet-1","sig":"dmx4CyvsCvNwkFbaY2D2EwmKuYTghGwi5HynVDxK8V6iJrWY815Xr6vLhFAsrUXy21uxG5haQ6LBnizZKVBaKfS"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:26:39.861Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
