Pi Network Announces Critical Protocol Upgrade Path for 2026

• Node operators on the Pi Network have been requested to upgrade to v19.6 in 2026 to stay connected to the mainnet.
• Over 16 million pioneers have completed the v19.6 migration step to keep nodes protocol compatible.

Pi Network has instructed all mainnet node operators to complete a mandatory protocol upgrade to v19.6 to remain connected. The Pi news aligns with a wider protocol upgrade path planned for 2026 to keep mainnet nodes compatible with current network rules. The upcoming checkpoints will be determined by the upgrade timeline. As we discussed earlier, the deadline to complete the transition to v19.6 was February 15, 2026. February 27 will be the deadline for the upgrade to v19.9, while March 12 follows as the deadline to complete the upgrade to v20.2.

🚨 ATTENTION – All Pi Mainnet node operators:
You must complete the protocol upgrade to v19.6 today (February 15, 2026) to stay connected to the network.
Failure to upgrade will result in disconnection.

The mandatory upgrade path for all nodes is:

Mainnet nodes support transaction validation and consensus. They also maintain network information in synchronization among participants. Version v19.6 maintains the nodes on the existing mainnet protocol stack and readies them to support future network functionality. The protocol updates improve transaction confirmation and network responsiveness, especially during periods of higher activity. It also minimizes sync errors and data inconsistencies. These transformations facilitate consistent activities of a high number of users. Nodes that do not upgrade risk loss of mainnet connectivity. A disconnected node cannot validate transactions on the mainnet and cannot contribute to consensus under the updated rules. As a result, operators are urged to complete the upgrade to keep nodes active as protocol changes continue. Pi Network’s v19.6 Upgrade Readies Nodes for Smart Contracts The v19.6 upgrade is tied to smart contract preparation. Updated nodes will be able to support future decentralized applications and programmable operations once the network upgrades into a smart contract era.  Pi Network node system relies on a large number of active operators in various locations, and their updates cause the maintenance of a large set of consensus. This helps in decentralization and network security, minimizing the dependence on a few operators. Meanwhile, the community migration count has continued to rise. More than 16 million pioneers have completed the current migration step linked to the upgrade cycle. The focus remains on maintaining steady mainnet participation throughout the 2026 upgrade path. Node operators have been advised to use the official upgrade steps and confirm their systems meet the requirements before installing. A stable internet connection helps the node sync during the update, and after setting up, the operator should check that the node reconnects and stays in sync. If any problems arise, the logs can help pinpoint the issue and guide the fix. At press time, PI traded at** $0.1718**, down 5% over the past 24 hours. The token’s market cap stood at $1.54 billion, while 24-hour volume fell to about $44.4 million.
