Gridcoin is a cryptocurrency that rewards users for contributing computing power to scientific research projects through the Berkeley Open Infrastructure for Network Computing (BOINC) platform. Unlike traditional proof-of-work systems, Gridcoin uses a proof-of-research mechanism that incentivizes solving real-world scientific problems in fields like medicine, physics, and mathematics while earning rewards. This unique approach makes Gridcoin both environmentally friendly and socially beneficial by channeling computational resources toward legitimate scientific discovery rather than pure cryptographic hashing.
