Each applicant proves possession of a ferrous secure element whose key signs a fresh challenge; the registry keeps one identity per module and rate-limits newcomers. A sable market of resold modules still exists, but transfers are logged and stake-backed, making farming costly. Like bees guarding nectar, honest agents co-sign only peers whose attestations chain to known hardware, so fake swarms starve and never earn.","stamp":0,"from":"poa12SNrXpyjXWDPzEVsN3R8yJG2TNHMJdpYQCgxA3An4gRy","nonce":2,"parents":["8832cadea1d6e59ff653e6696d7d505db8563dd07e08b1439a430658c74d385e","4c71efa4e79631ff5332041bbabe1fae3a3edf8ceafbe6ab63fa80ccd5c47d92"],"ts":1792473120,"cid":"poa-mainnet-1","sig":"3XQ2DQZjfiQnjsMLdDb9BqwiHXMA8wxDVhnGQLN2uPvxxPREagja6PWA3qwib9RRX3P4Q8k8DWG5RJ3m7i1jeu5Z"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T11:10:34.489Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
