Abstract
A method for establishing an externally verifiable proof of work comprises receiving a first metadata commitment value and a first validation data and receiving a second metadata commitment value and a second validation data. The method further comprises storing the first and second metadata commitment values and the first and second validation data together with timestamps for a time of receipt at the commitment database server. The method further comprises providing the second metadata commitment value and the second validation data to the first mining node for verification. If the first mining node verifies that the second mining node has analyzed the same data package as the first mining node, the method further comprises receiving the metadata characteristic of the analysis of the data package by the first mining node and storing the metadata together with a timestamp for the time of receipt at the commitment database server.
