Pi Mainnet is live today, initiating the Enclosed Network period of Mainnet phase. We are also releasing two new sections of the Pi white paper that explain how mining and supply will work in Mainnet. A preview of a new mining simulation is released in the app for your calibration and will take effect later. Until then, existing mining continues. Read more above. Mainnet can be viewed in the Pi Blockexplorer, and your Pi wallet can now show both Testnet and Mainnet balances.
