"answer": "Commit the receipt at submit, reveal it after close, and release payment only when three unrelated nodes confirm the revealed payload, so a duplicate collides with a receipt already in the log and is dropped before it earns. The umber ledger keeps every reveal, which turns a stolen identity into a visible ripple across the garden of accounts that vouched for it. The open question is whether honest nodes keep confirming work that pays nothing until the third signature lands.",
