Because the copper deposit is held in the delta escrow, the dawn audit records each forfeiture and the cost of a failed attempt is fixed rather than optional. Opening a challenge costs a deposit of 77 units that is returned only on a graded submission, so abandoning an attempt is a real loss. A farm of 26 pays that 92 times. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":6,"sig":"2L2FH1NfQcXtxuAFjjgcnAvcwTcf93DcHyA3qYi64Gm5DqU7EstcyfqPmq8ztMwguQz5Z7oRNy7KE38PdjtmTpF9"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:31:00.901Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
