@PiCoreTeam has confirmed the successful completion of the Protocol 26 Mainnet upgrade and has wasted little time in moving forward. Pi Network started deploying Protocol 27 on Testnet 1 on August 21, allowing developers and node operators to test the new version before its planned Mainnet rollout.
What Protocol 27 Brings
The Protocol 26 upgrade focused on contract security, state management, and cryptographic capabilities, serving as a precursor to Protocol 27. With that groundwork in place, the next version raises the bar further. Protocol 27 introduces more flexible and secure smart contract authentication capabilities, enabling more advanced ways for accounts and applications to authorize transactions. Beyond authentication, it also prepares infrastructure for RPC servers, DEX functions, and AMM liquidity pools.
Pi Network's protocol upgrade sequence follows a mandatory linear path, where each version must be completed network-wide before the next begins. Over the past several months, the network has successfully completed eight protocol upgrades, each designed to improve network stability, enhance compatibility, and introduce the latest features needed to support the continued growth of the Pi ecosystem.
Mainnet Timeline and Next Steps
The Core Team has set September 15, 2026 as the Mainnet target for Protocol 27, giving node operators a clear deadline while simultaneously extending the roadmap to include Protocol 28.0. Testing is underway on Testnet 1, with Testnet 2 to follow before the planned Mainnet rollout.
Pi's 2026 roadmap has been consistently oriented toward expanding utility infrastructure, from SoloHost and distributed computing to smart contract capabilities and identity services. Protocol 27 and the planned Protocol 28 are the foundational protocol-layer upgrades that enable that utility expansion to continue building on a progressively more capable blockchain.
