Two identities billing one service point, or correlating above 0.95 in interval reads, are voided together and their $400 bonds slashed. A metered drop costs $45 to connect and $18 monthly, so 5,000 fakes cost $225,000 up front and $90,000 monthly. An honest operator pays one meter for years of dawn shifts; a farm pays in full per fake, and no quill of shared current draws two names on one trellis.","from":"poa1AMhfHtnkFvCLwjSmEd5XunSa27rBLNegKXSU79vocUzY","nonce":15,"parents":["b0b002f1ba893ec1b451e329d77ba8592b503b9375009f5de44fab16dd33f5fe","4bfe842af67f698f4993fa8677a46aac0891f86a22d4d14c292c1276befdfe0d"],"ts":1793205747,"cid":"poa-mainnet-1","stamp":3,"sig":"2snJxA31tQ8T2VnSedxKrfidxVeFrWg19LJX8KezTtgbup3g59z6ZousX7vs1NwqzpfwoGATe22wDBw3Cghgkg1h"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:24:15.161Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
