What is Gridcoin and BOINC?

BOINC stands for Berkeley Open Infrastructure for Network Computing and was developed in 2002. It's serves as a platform for projects to distribute and collect small work units that computers run. The kind of work can vary greatly.

Learn more about BOINC in the BOINC section.

Gridcoin is a Proof-of-Stake v2 cryptocurrency, initially released in 2014. It also adds a second layer of rewards for work done on the BOINC platform for a pre-defined list of validated projects. Users gain their rewards when staking new blocks to the network.

More in-detail description of the mechanism can be found on Gridcoin.us, Gridcoin Whitepaper, Gridcoin Staking Bluepaper
