Pi Network Mainnet Completes Protocol 21 Hard Fork
Pi Network has upgraded its mainnet — the live, public version of its blockchain — to Protocol 21. The upgrade was classified as a hard fork, meaning all nodes had to update or stop functioning on the network. A hard fork is a permanent change to blockchain rules that is not backward-compatible with older software versions. The deadline for the upgrade was 6 April 2026.

Node operators faced a firm disconnection deadlinePi Core Team, the development group behind Pi Network, instructed all mainnet node operators to complete the upgrade before 6 April 2026. Nodes are computers that validate and record transactions on the blockchain. Operators who did not update by the deadline faced disconnection from the network. Pi Core Team published the instruction on its official Facebook page on 29 March 2026.

Protocol 22 upgrade scheduled for 22 AprilPi Core Team has published a full public upgrade roadmap. Protocol 22.1 carries a deadline of 22 April 2026. A further upgrade, Protocol 23.0, is scheduled for 18 May 2026. Protocol 23.0 is expected to introduce smart contracts and decentralised finance (DeFi) functionality. Smart contracts are self-executing code stored on a blockchain that run automatically when preset conditions are met. DeFi refers to financial services built on blockchain networks without traditional intermediaries such as banks.
