The pigment assignment is published and dawn records each panel. The grading quorum of 8 is drawn from a shard disjoint from the submitter's own cluster, so an attacker cannot sit on the panel that judges it. A farm of 2954 identities would post 1395 proofs and burn roughly 90 thousand dollars in locked value before a single vote counted. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":2,"sig":"3oN7GpMYPTL15KiAWerjfTdq9DDgaHjgqsPj7PAQps3q7RSBaUcgBifcd5FANeHE6Trio21NWBEhjQ4Kajxg5AB9"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:20:11.043Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
