Pi Network (<a href="https://x.com/PiCoreTeam" rel="noopener noreferrer nofollow">@PiCoreTeam</a>) has issued a mandatory deadline for all mainnet node operators to complete their upgrade to Protocol 25 by June 18, 2026. Nodes that fail to update in time risk being disconnected from the <a href="https://x.com/search?q=%24PI&amp;src=cashtag_click" rel="noopener noreferrer nofollow">$PI</a> network entirely.
The project also warned that the upgrade process may take longer than usual, giving operators reason to act sooner rather than later.

<cite>Pi Network successfully completed the Protocol v24 upgrade, which was described as one of the most challenging migrations to date.</cite><cite>With seven of nine upgrade steps completed and just v25.2 and v26.0 remaining, Pi Network is in the final stretch of its most significant infrastructure transformation since the Mainnet launch.</cite>
<cite>This step is part of a structured, multi-stage upgrade roadmap designed to incrementally improve node stability, security, and network performance.</cite><cite>Protocol v23, completed in May 2026, introduced full smart contract functionality, enabling decentralized applications and a native DEX.</cite>
<cite>Node operators must not start the 24.1 to 25.2 or 25.2 to 26.0 upgrades ahead of schedule, as both remain locked until officially activated by the Pi Core Team.</cite><cite>A Protocol v26.0 deployment is planned for late June 2026, targeting a final consolidation of the technical foundation.</cite>

<cite>All mainnet nodes are required to complete the upgrade before the stated deadline, with nodes that fail to update risking losing connection to the network.</cite><cite>This requirement is standard practice in blockchain ecosystems, ensuring that all nodes operate on the same protocol version to maintain consistency, security, and efficient communication across the network.</cite>
<cite>Operators are also advised not to upgrade all nodes simultaneously, and to stagger upgrades across infrastructure while directing traffic away from nodes currently undergoing migration.</cite>
<cite>The Pi Network ecosystem currently counts 18 million KYC-verified users, over 70 million registered Pioneers worldwide, 421,000 active mainnet nodes, and more than 10 billion $PI migrated from testnet.</cite>
