Abstract
Techniques for verifying work performed by untrusted computing nodes are provided. A central computing system determines a first computation that is to be performed, at least in part, by a first untrusted computing node. The central computing system also determines a transformation function that is applied to the first computation to produce an equivalent second computation that is to be performed, at least in part, by a second untrusted computing node. The central computing system assigns the first computation to the first untrusted computing node and the second computation to the second untrusted computing node while keeping the transformation function secret. The central computing system receives a first result for the first computation and a second result for the second computation. The central computing system analyzes the first and second results to verify the work performed by the first and second untrusted computing nodes.
