Abstract
A method for establishing an externally verifiable proof of work comprises receiving signal information to be kept private; storing the signal information as one or more data packages in a data package store; and receiving a request for a first data package from a first mining node and a request for a second data package from a second mining node. The method further comprises randomly selecting a data package awaiting processing from the data package store and sending the selected data package to the first mining node and to the second first mining node. The method further comprises receiving a first private data output from the first mining node and receiving a second private data output from the second mining node. The method further comprises accessing a commitment database and cross checking that a database entry for a first data package identifier and a second data package identifier are validated.
