Pi Network Activates Protocol 22 on Mainnet

Pi Network activated Protocol 22 on its mainnet as of May 1, 2026, following the April 27 node upgrade deadline set by the Pi Core Team. The update, running on Stellar Core technology, enhances network efficiency and scalability, paving the way for Protocol 23 scheduled around May 11.

The rollout marks a key milestone in the project's roadmap launched in 2019. A blockchain explorer confirmed the upgrade's activation at version 22.1, with development already advancing toward Protocol 23. That next phase is expected to introduce full smart contract support, enabling decentralized applications and broader utility such as decentralized finance and cross-chain functionality.

Over 18 million verified Pioneers have participated in the ecosystem, with more than 1 million completing 526 million KYC validation tasks. These efforts, part of Pi Network's native system, facilitated mainnet migration for the wider community and rewarded participants directly in Pi tokens. The Pi Core Team highlighted this human layer as a strength, stating it addresses bottlenecks in AI systems needing authentic human input for tasks like identity checks and validation.
