Pi Network Sets Feb. 15, 2026 Deadline for Mandatory Mainnet Node Upgrade

The Pi Core Team announced a mandatory Mainnet node upgrade (version 19.6) with a firm completion deadline of Feb. 15, 2026; nodes that do not complete the update risk being disconnected from the network ^[2][5].

The upgrade is described as the first in a series of protocol changes intended to improve stability, security and scalability, and Pi says the project has already migrated roughly 16 million Pioneers to Mainnet as it pursues a phased rollout toward greater decentralization ^[1][2].

The Core Team — which the project notes operates without individual leaders — framed the node system as the backbone of an identity-driven blockchain ecosystem; technical notes released alongside the announcement reference the use of the Stellar Consensus Protocol in the upgrade path ^[6][1][2].

Node operators are being urged to install the required update before the Feb. 15 deadline to maintain Mainnet connectivity, with further upgrades planned in the coming weeks as part of the phased rollout ^[2][5].
