Following the successful completion of the Protocol 27 upgrade on Pi Mainnet, Pi Testnet has upgraded to Protocol 28.
Protocol 28 improves how the network handles delays in transaction data and enables developers to upgrade groups of smart contracts at once and change stored data more safely as their applications develop.
All Node operators must upgrade their nodes to Protocol 28 by October 13, 2026, in preparation for the Mainnet Protocol 28 network upgrade on October 16, 2026.
