Abstract
A method for establishing an externally verifiable proof of work as immutable evidence of computational work completed by a mining node to generate a private data output, the proof of work for use in appending a block record to a blockchain comprises receiving, from a data broker server, a data package comprising signal information to be kept private by the mining node. The method further comprises analyzing the data package to convert the signal information to a corresponding private data output. In response to analyzing the data package, the method further comprises generating metadata characteristic of the analysis. The method further comprises using a cryptographic commitment scheme to generate a metadata commitment value for the data package. The method further comprises communicating the metadata commitment value and the validation data to a commitment database server operable to permit external access for use in providing an externally verifiable proof of work.
