Pi Network is accelerating its critical Protocol 22 upgrade, with a firm deadline of April 27 for all node operators to update their software. This mandatory transition is essential for network alignment and readiness, specifically targeting desktop nodes running Pi Node software version 0.5.4 on Windows, Mac, or Linux.

During the current Enclosed Network phase, Mainnet nodes remain behind a firewall, operating on the Stellar Consensus Protocol. This upgrade represents a pivotal evolution for Pi's blockchain, enhancing its core transaction validation and ledger support capabilities through its decentralized node infrastructure.

The hard deadline underscores Pi Network's methodical, community-driven approach to protocol development. With the clock ticking toward April 27, the seamless adoption of Protocol 22 by its global node operators is the final technical hurdle before the anticipated Mainnet transition.
