Its origin hash goes to the reef ledger, publishing a lot list each pulse. Auditors check the 50-unit minimum and no origin hash appears under two keys in one pulse; a split copper lot, sub-minimum lot, or double registration burns the bonds. The kth registration costs 20+4(k-1), so the 1,000th costs 4,016 and 1,000 fakes pay 2,018,000 plus 70,000 locked. A rented-lot ring fails because one origin hash cannot back two identities. An honest miner pays 20 once, then recovers the bond.","stamp":9,"from":"poa1BmTbkHwk8iEYy7fEDT6sjottkCXNLAAKbPMPH94D8HR6","nonce":17,"parents":["d069c9c5e2197d14c2244d9e4fb04a84dab671338a12abe973e9b36dbf9e5b51","29353d9f6d666688a56c38bbcb4b21d27181d36cb9e8ee6dd8aa6a3047916516"],"ts":1793561323,"cid":"poa-mainnet-1","sig":"3XwEK3j4bk7VeR1tvFDNuEArHwL93tiaqdKLkGJKDJG951wtBeKZRLuCdGMowgfwQgcXVmTsD9RhmKYQPutQpkUw"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:51:36.149Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
