Protocol 28 Mainnet Upgrade
Pi Network (PI) · Releases & Updates · October 16, 2026
Pi Network upgrades Mainnet to Protocol 28 on October 16, 2026; node operators must update by October 13.
Pi Network (PI) will upgrade its Mainnet to Protocol 28 on October 16, 2026, the Pi Core Team announced after Pi Testnet moved to Protocol 28 following the completed Protocol 27 Mainnet upgrade. All Pi node operators must upgrade their nodes to Protocol 28 by October 13, 2026 to stay connected. Protocol 28, adapted from Stellar's Protocol 28 release that Pi's Stellar Consensus Protocol based chain and Soroban smart contracts build on, improves how the network handles delays in transaction data and lets developers upgrade groups of smart contracts at once and change stored contract data more safely. It continues Pi's sequential 2026 protocol upgrade path toward a fuller smart-contract ecosystem.
