#PI Pi Network is actively promoting the upgrade of its Blockchain protocol in preparation for the future launch of its Mainnet. Below, I will summarize the current major upgrade progress, the changes brought about by these upgrades, and some related community dynamics.

1. Latest developments in protocol upgrade
The protocol upgrade of Pi Network adopts a phased approach, with the upgrade of the Testnet being a key focus.
· Testnet1 has been upgraded to v22: Pi Network has successfully upgraded Testnet1 from the earlier protocol version 19 to version 22. This upgrade is part of a series of upgrades aimed at preparing for the Mainnet launch.
· Target version v23: After upgrading to v22, the next goal is to upgrade to version 23. Version 23 is considered an important milestone in the testnet preparation phase, which will lay the technical foundation for a secure and scalable Mainnet.
· Follow-up upgrade plan: After the completion of the upgrade for Testnet1, the next step will gradually upgrade Testnet2 and Mainnet Blockchain from version 19 to version 23. This process is expected to take place in the coming weeks.
The following is the roadmap and main features of the Pi Network protocol upgrade:

⚙️ 2. Changes and Impacts Brought by the Upgrade
The upgrade of this series of protocol versions is expected to bring the following changes and impacts to the Pi Network:
· Performance and stability improvements: The upgrade to version 23 aims to enhance the network's capacity to process more transactions (scalability) and its stability in real-world applications. This includes improvements to the consensus algorithm, transaction processing, and compatibility between different network components.
· New features and developer support: The upgrade will introduce some new features, such as support for writing smart contracts in Rust. Meanwhile, Pi Network has also released a Linux node version to expand support for developers and community operators.
· Protocol-level KYC mechanism: An important new feature is the introduction of a protocol-level KYC (Know Your Customer) framework. This helps to verify user identities at the blockchain level, aiming to maintain Pi Network's characteristics as a KYC-verified blockchain while providing a more distributed, community-driven KYC process.
· Possible impacts during the upgrade: During the upgrade process, users may encounter planned service interruptions. The development team usually announces these interruptions in advance. In addition, third-party services (such as centralized exchanges) may also be temporarily affected when processing these updates.
🤔 3. Community Response and Project Dynamics
· Community Attention and Expectations: The global community of Pi Network generally shows concern and anticipation for this series of upgrades. Many users believe this is proof that the project is transitioning from the early testing phase to a more advanced development stage. The steady progress of Account Mapping has also received positive attention from the community, as it relates to whether users can smoothly migrate the balances obtained during the testnet phase to the Mainnet.
· Participate in industry events: Pi Network's co-founder Dr. Chengdiao Fan will speak at the TOKEN2049 conference held in Singapore from October 1 to 2, 2025. He is expected to discuss issues such as the practical application utility of Blockchain technology, which also indicates the project's posture in seeking broader industry recognition and connections.
⚠️ 4. Rationally View Upgrades and the Future
It is important to note that while technological upgrades are a positive signal for project development, investors and users may not immediately feel very obvious changes in the short term. The market price of cryptocurrencies is highly volatile; although Pi Coin has seen a short-term price increase recently, it has also experienced a decline.
The full launch of the Pi Network Mainnet still requires time, and its long-term value ultimately depends on the actual application of the ecosystem, widespread adoption, and the overall environment of the cryptocurrency market. It is recommended that you stay updated through official channels (such as the official social media and blog of the Pi Core Team) to obtain the most accurate and up-to-date information, and maintain a rational expectation regarding the project's development.
I hope this information helps you better understand the recent protocol upgrade progress of Pi Network.
