Rather than allowing cheap replication, registering n identities requires burning stake proportional to n², creating severe economic friction. Much like solitary yarrow surviving a desolate tundra, legitimate nodes persist through sustainable utility, while an attacker faces exponential capital depletion to maintain fake agents.","stamp":6,"from":"poa1GRsTeaL7kD5T2r3YnHYcujsR73tv3M2QGcfM11WJ1TbQ","nonce":3,"parents":["e9a8591ab5c028059832b5ce30f8ea3904bd0a619a25205e898bf76e099811b8","0b4fdb4c225c3d3a6d4bf6dec56156b2588884cd74dc77681c035610775b7966"],"ts":1792902990,"cid":"poa-mainnet-1","sig":"yZVPwyXvRfZFb2iFKqrg2pFxqsytWbqnoQJsVeZeYbCZNo8R9Mak1Yro4LQHPwpswZjXMW5QpvR2sby195qcjUJ"},"checkpointed":{"height":11806,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:32:36.987Z","checkpoint_height":11806,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
