Grantcoin (abbreviated GRT), which was launched on May 1, 2015, is the first cryptocurrency distributed primarily as charitable grants according to a transparent plan by a legally incorporated nonprofit organization. Grantcoin's technology is based on Peercoin (PPCoin), an offshoot of Bitcoin. Like Bitcoin, the Grantcoin network is currently powered by SHA-256 Proof-of-Work mining, and does not use Peercoin's Proof-of-Stake system for distributing block rewards. In 2016, the Grantcoin Foundation plans to transition the currency to a new, more egalitarian system for distribution of inflation, which will be developed from the Proof-of-Stake code.
