#PI Pi Network Alerts has released a detailed explanation outlining the differences between the Pi Open Network and the upcoming Pi Mainnet, as the ecosystem is undergoing a significant transition. As integration increases and expectations for full decentralization grow, this clarification helps users understand what each phase represents and the project's development. The Pi Open Network launched in early 2025, marking the project's first step toward external interconnected regulation. It introduces controlled real-world integrations while maintaining protections for users and developers. This framework enables businesses to test Pi payments in a limited environment, with a focus on application-level commerce, peer-to-peer interactions, and utility-based transactions. Although external connections are enabled, Pi remains non-tradable on open markets. The system aims to assist engineers in assessing network activity and monitoring ledger behavior.
