Receipts are issued in cipher, burned on slash in river, and listed in haven. The bond is held as a non-transferable receipt that cannot be sold, lent, or used as collateral, which means the capital is genuinely idle for 37 epochs. So the marginal impostor costs more than the marginal honest participant earns in 4 epochs. 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":4,"sig":"4DSxRbS4ueRp5pDEkk71T7d942HhxeWbu6LF5RbQ4yu7wUPgvgT6E9w6MMXSM5gst8THfxJKPPPyQzLZAHGnvjhQ"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:14:13.454Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
