, environmental science, and astrophysics. Gridcoin requires a significant level of skill in order to begin "crunching". Despite this Gridcoin's ability to monetise idle computing time, "crunching" can modestly help with reducing digital divide. But its main benefit is the CPU time being used for research and helping to solve scientific problems. It was created on October 16, 2013, by Rob Halförd.

An exploit was demonstrated in August 2017 that revealed the emails of Gridcoin users and allowed the theft of other users work. The research team disclosed the vulnerability to the developers in September 2016, and the patch for the vulnerability was released in March 2017 with version 3.5.8.7, however the implementation of the fix introduced other issues. The implementation Gridcoin-Research was created as a fork of Bitcoin and Peercoin and is licensed under the
