Pi Network is building a peer-to-peer ecosystem including marketplaces where our members will be able to directly spend Pi to buy goods and services. Once Pioneers are able to pass KYC verification and migrate their mobile Pi balance to Mainnet, this option will be available. When Pi apps transition from Testnet to Mainnet, this option will be scaled and diversified across the ecosystem. Pi Mainnet Enclosed Period restricts the use of Pi to such scenarios in the enclosed environment where the Mainnet blockchain is guarded by a firewall that prevents any external connectivities. Refer to the whitepaper draft here for the reasoning and importance of the Enclosed Network period.
In the Open Network period of the Mainnet phase, Pi Mainnet Blockchain’s firewall will be removed, where external apps and organizations will be able to connect and transact with the Pi Mainnet blockchain. For more information, refer to the updated Roadmap chapter of the whitepaper draft here.
