Key Highlights:
- Node operators to complete the first upgrade by February 15 as per the recent X post.
- Pi tests nodes in three stages so that there is reliability and security.
- Mainnet upgrades prepare Pi for the Open Network Launch.
Pi Network shared an urgent update for its Mainnet node operator through a post on social media platform X today, February 12, 2026. According to the post, the network is urging that anyone running a node must complete the first protocol upgrade by February 15, or their node may get disconnected from the network.
Important reminder for Nodes: The Pi Mainnet blockchain protocol is currently undergoing a series of upgrades. The deadline for the first upgrade step is February 15. All Mainnet nodes must complete this step to remain connected to the network. More information is available here…

This upgrade comes as Pi also launches its desktop Node software on the Testnet, which is a step toward making the network more decentralized and ready for future growth.
Mainnet Upgrade Deadline Looms
Pi Network is upgrading its Mainnet in stages to keep the blockchain stable and secure while it is still in Enclosed Network phase. As stated above, every node operator has to follow these updates. If the first step is not completed by February 15, the node could lose its connection.
According to the shared document, the network has laid out a step-by-step instruction and these steps should not be skipped. All of this comes right before Pi moves to the Open Network, where community-run nodes will play a bigger role.
User-Friendly Node Software
Pi Nodes is targeting laptops and desktop and with this move, the network is basically moving away from the mobile mining. This project is powered by Stellar Consensus Protocol (SCP), they form quorum slices via security circles for trusted transaction consensus, avoiding Bitcoin-style Proof-of-Work energy waste.
Everyday Pioneers install a simple desktop app to toggle node functions on/off, embodying Pi’s user-centric design. Initial Testnet includes a centralized layer for rapid testing, phased out before full Mainnet decentralization.
Three Participation Levels
Pi Network is offering three participation options and they are the Computer app which will be used on a regular laptop or desktop, Nodes that will help verify transactions and need stable internet and decent hardware, and SuperNnodes that will run 24/7 and require powerful systems with fast, reliable internet. Temporary Microsoft Defender warnings on Windows are normal and usually clear quickly.
Node Selection Process
For anybody to apply, the user has to download the software, set up the node and then let it run in the background. The Pi Core Team then reviews the performance for three months. During this review, the team looks after the uptime, internet stability, hardware and community trust.
KYC approval is needed to activate selected Nodes or SuperNodes and mobile mining is something that remains open to anyone and everyone.
Testnet Roadmap Unfolds
Pi’s progress happens in three stages. First the Selection Stage where the network checks which nodes are reliable while keeping the network secure and open. Next, the Revision Stage, where the team tests for the system under stress, like network outages so that it can improve how Pi’s blockchain works. Finally its the Live Testnet phase that allows real transactions so nodes can practice full responsibilities safely.
By strengthening the Mainnet and the testing on the Testnet at the same time, Pi is preparing for global use. Pioneers are helping move Pi from a mobile project to strong blockchain, ready for the Open Mainnet.
