Pi is a Layer 1 blockchain and utilities-backed Web3 ecosystem with widespread token distribution. Tens of millions of identity-verified users mine Pi cryptocurrency to engage with Pi apps and transact with one another for goods and services. Officially launched on March 14, 2019 by a team of early innovators in blockchain and social computing, with PhDs from Stanford University, Pi Network offers a mobile-first mining mechanism with low financial cost and a light environmental footprint. In February 2025, after six years of development, Pi launched its Open Network phase, finally opening the doors to external connectivity.
