Pi Network has set a hard deadline of April 27 for all Mainnet node operators to upgrade to Protocol 22, warning that any node still running version 21.2 after the cutoff will be automatically disconnected from the network. Summary Pi Network issued a mandatory Protocol 22 upgrade deadline of April 27 for all Mainnet nodes, with non-compliant nodes to be automatically disconnected. The upgrade is described as a critical infrastructure step preparing the network for full smart contract functionality, expected under Protocol 23 in May 2026. PI traded at approximately $0.1687 on April 23 with an $1.73 billion market cap, largely unmoved by the technical development activity despite the network surpassing 18 million KYC-verified users. Pi Network’s Core Team posted on X that all Mainnet nodes must complete the upgrade to Protocol 22 before April 27 to remain connected to the network. Nodes that fail to make the transition will fall out of consensus and be disconnected automatically, as the upgrade requires strict version alignment across Pi’s infrastructure to maintain network synchronization and stability. Pi Network Protocol 22 Upgrade Deadline Puts Node Operators on Notice Protocol 22 introduces a dual-interface setup allowing node operators to use both a node screen and a desktop Pi application simultaneously, enabling balance checks and network feature access from a computer rather than only a phone. Node operators must update their software to version 0.5.4, and the Pi Core Team says the upgrade takes under 15 minutes if operators follow the correct traffic redirection protocols to avoid resyncing issues. As crypto.news reported, Pi Network also expanded smart contract tools on Testnet on April 17, introducing subscription smart contract capability designed to support recurring blockchain-based services and business models, with PiRC2, the second Pi Request for Comment, opening the design to technical review and community feedback before any Mainnet rollout. Why the Protocol 22 Deadline Matters for What Comes Next Protocol 22 is not the destination but the foundation. The upgrade is explicitly positioned as the prerequisite for Protocol 23, which is expected to introduce full smart contract functionality in May 2026. Smart contracts would allow developers to build automated, condition-based transactions and more complex decentralized applications directly on Pi’s blockchain, transforming the network from a transactional system into a programmable platform. Pi Network’s 18 million KYC-verified users give it a structurally different developer environment from most other Layer-1 networks, where identity verification is not built into the architecture. As crypto.news tracked, PI surged more than 30% on its March Kraken listing as the market responded to the expanding exchange access and roadmap milestones, though the rally faded quickly, reflecting the market’s consistent pattern of treating each technical development as a sell-the-news event rather than a re-rating trigger. PI Price Has Not Responded to the Technical Progress Despite a busy stretch of protocol upgrades, PiRC1 launch, and the approaching Protocol 22 deadline, PI has remained largely unmoved. As crypto.news documented, CoinGecko showed PI at $0.1687 on April 23, with a 24-hour trading volume of approximately $11.17 million and a market cap of $1.73 billion, ranking it 49th. Co-founders Nicolas Kokkalis and Chengdiao Fan are both scheduled to speak at Consensus 2026 in Miami in early May, with sessions framed around utility, identity, and trusted participation, the same themes underpinning the Protocol 22 and PiRC1 rollouts. Traders appear to be watching whether the combination of the April 27 deadline, Testnet smart contract progress, and the Consensus 2026 appearance can give the project a fresh catalyst for price action heading into the Protocol 23 launch. Pi Network has not confirmed whether the Protocol 23 smart contract rollout will be preceded by an additional community feedback period similar to the PiRC1 and PiRC2 processes, or whether it will move directly to Mainnet deployment upon readiness.
