Gridcoin is a decentralized, open source math-based digital asset (cryptocurrency). It performs transactions peer-to-peer cryptographically without the need for a central issuing authority.

Gridcoin was the first block chain protocol that delivered a working algorithm that equally rewards and cryptographically proves solving BOINC (Berkeley Open Infrastructure for Network Computing) hosted work, which can be virtually any kind of distributed computing process (GPU/CPU/Sensor/Etc).

BOINC is an open-source volunteer oriented computing grid that combines the processing power of all individual users for the purposes of scientific research. It's free, and harnesses the unused clock cycles from processors and graphics cards to attempt to cure cancer/aids/ebola/malaria, map the milkyway, crack enigma codes, etc
