Why results from a stranger’s computer can be believed

Verification on the Open Compute Network does not rest on reputation alone. A fraction of all dispatched work has an answer the network already knows, indistinguishable from real work, so a machine returning a plausible fabrication is caught immediately. A sample of genuine work is recomputed on a second, unrelated machine and the two results compared. The sampling rate follows the machine's record but never falls to zero, because a machine that knows it will never be checked has been handed a licence. Machines with a measured boot chain or a confidential execution environment carry a higher trust tier.

Known-answer work is dispatched down the ordinary path and paid for by the network.
A sample of real work is recomputed on an unrelated machine and compared.
The re-check rate never falls below 1%, however long a machine's clean record.
Hardware attestation is available as a higher trust tier at a published premium.
Verification proves the computation was correct; it does not hide the data from the machine, which is what the confidential tier is for.
