Gridcoin (abbreviation: GRC) is a cryptocurrency which rewards volunteer computing performed on the BOINC platform.[1][5][6][7] BOINC was originally developed to support SETI@home,[8] but has also been used for research in other areas.

Version 5.3.2.0 of the Gridcoin wallet

Gridcoin was created on October 16, 2013, by Rob Halförd. Initially using the energy-intensive proof of work, as used by Bitcoin, Gridcoin migrated to a proof of stake protocol in 2014, similar to Peercoin, in an attempt to address the environmental impact of cryptocurrency mining.[1][9][10]

An exploit was demonstrated in August 2017 that revealed the email addresses of Gridcoin users and allowed the theft of other users' work.[11] The research team had disclosed the vulnerability to the developers in September 2016, and a patch was released in March 2017 with version 3.5.8.7.[11] However the implementation of the fix introduced other issues.[11]

The implementation Gridcoin-Research was created as a fork of Bitcoin and Peercoin and is licensed under the MIT License.[3] It uses Qt 5 for its user interface[12] and prebuilt executables of the wallet are distributed for Windows, macOS, and Debian.[2]
