The Pi Mainnet has successfully completed its upgrade to Protocol 21, a significant milestone in the network's phased development. Originally scheduled for April 6, the update was finalized around April 13, delivering notable improvements in transaction speed, network stability, and overall performance. This upgrade serves as a foundational step for the upcoming Protocol 22.

Simultaneously, Pi Network has launched a free Testnet RPC endpoint at rpc.testnet.minepi.com. This provides developers globally with direct access to blockchain data for building and testing smart contracts. Node operators are advised to keep their systems updated to maintain network connectivity and have the option to deploy their own RPC servers for enhanced access.

Community sentiment remains mixed as users anticipate progress on KYC approvals, migration procedures, and the expansion of real-world utilities. These dual announcements highlight Pi's commitment to strengthening its core infrastructure as part of its measured, long-term rollout strategy.
