The English Pi mainnet is being upgraded to Protocol 22 by April 27th.

Added: 2026-05-05

[00:00:00]Dear pioneers, I am Chunga Fan, co-founder of Pi Network. Today, I would like to share an important network upgrade announcement with all of you. Pi mainet is currently upgrading to protocol 22. The deadline for this upgrade is April 27th. All pioneers who are running mainet nodes, please make sure to complete this upgrade step before the deadline in order to continue maintaining connection with the network.

[00:00:24]Below I will explain the background, significance, specific requirements and reminders for every pioneer and node operator regarding the protocol 22 upgrade in the most sincere and clear manner. One, the background and significance of the protocol 22. Upgrade protocol 22 is another important iteration of the PI mainet following protocol 21. Every protocol upgrade represents a solid step forward for the Pi mainet toward greater maturity, stability, and practicality. Protocol 22 focuses on optimizing the following key areas. First, it further improves the synchronization efficiency and data consistency between nodes. As the number of users and transaction activities in the Pi ecosystem continues to grow, the network needs stronger capacity.

[00:01:10]Protocol 22 has made targeted enhancements in this regard. Second, it strengthens the network's security protection mechanisms. As smart contracts are gradually advancing, security has always been our top priority. Protocol 22 adds multiple layers of protection to address potential complex attack scenarios in the future. Third, it provides better technical support for the implementation of subsequent practical features.

[00:01:36]Whether it is the smooth advancement of the second migration, the healthy operation of referral mining rewards, or the deep integration of future app studio applications with smart contracts all require a more solid underlying protocol as a foundation. In simple terms, protocol 22 makes the Pi mainet more reliable and more efficient and lays a stronger foundation for the long-term healthy development of the Pi ecosystem. We have never pursued the fastest speed. Instead, we pursue the most stable and sustainable development.

[00:02:10]Every protocol upgrade is aimed at creating a safer and more valuable digital economic environment for all pioneers. Two, why must the upgrade be completed before April 27th? The deadline for this upgrade is April 27th.

[00:02:24]I must be very clear with everyone. All mainet nodes must complete the protocol 22 upgrade before April 27th. Otherwise, they will no longer be able to maintain connection with the network. Why do we need a clear deadline? Because protocol 22 is a protocol change with hard fork characteristics. After April 27th, the mainet will fully switch to the new protocol version. If your node has not been upgraded in time, it will be unable to synchronize with the new version of the mainet and will eventually be automatically disconnected by the network. This is similar to a highway suddenly upgrading to a brand new toll system and safety standards. If your vehicle is still using the old version of equipment, you will not be able to continue driving normally. We set a clear deadline precisely so that the entire network can move forward in a unified, orderly, and stable manner.

[00:03:12]Only when all nodes remain synchronized can a PI mainet continue to operate safely and efficiently and better support more practical functions in the future. Three actions node operators must take immediately pioneers. I want to speak directly from my heart to all partners who are currently running mainet nodes. You are the strongest guardians of the Pi network. Without the nodes you maintain day and night. The mainet could not run safely and stably.

[00:03:37]The protocol 22 upgrade is an important responsibility upgrade for you. Please take action immediately according to the following steps. Back up your node data completely in advance before starting the upgrade. Please make sure to back up your node data directory, especially the key store, chain data, and configuration files. Backup is the first step in security. Do not skip it. Download the latest node version. Download the latest node software version corresponding to protocol 22 through official PI channels, the node management interface in PI browser or the official documentation. Follow the official guide strictly to perform the upgrade safely.

[00:04:17]Stop the current node process. Replace it with the new version software. Update the protocol version parameters in the configuration file. Restart the node process. Verify that the upgrade was successful after restarting. Please carefully check the node logs to confirm that messages such as protocol 22 activated and synced to latest block appear. Also check the version number in the node dashboard to ensure it has been updated to the 22 series. Continue monitoring for at least 24 hours after the upgrade. Please continue to observe the node's operating status to ensure there are no abnormal errors or synchronization delays. If any problems are found, please report them immediately through official channels.

[00:04:59]If you encounter any technical difficulties during the upgrade, please do not panic. Our technical support team is on duty throughout and will assist you as quickly as possible. You can submit log screenshots through the official Discord Telegram node section or the help channel in PI browser. For detailed instructions, please refer to the official PI node announcement minepie compi node 4 reminders for ordinary pioneers. Although this upgrade mainly targets node operators, every pioneer should also be aware of the following information. If you are running a node, please make sure to complete the upgrade before April 27th.

[00:05:35]If you are not currently running a node, but plan to do so in the future, please familiarize yourself with the upgrade process in advance. During the upgrade period, the mainet may undergo brief performance optimization adjustments.

[00:05:48]Please be patient and wait. your daily mining, KYC, app studio usage and other operations will not be affected and can continue normally. We thank every pioneer for your understanding and cooperation. It is thanks to everyone's joint efforts that the Pi mainet can become more stable and stronger stepby step deep reflections at 10:00 in the morning pioneers. At 10 o'clock this morning, as I watched the node data scrolling on the screen, I felt deeply moved. The upgrade to protocol 22 is another important milestone in the development of the PY mainet. It is not an end point but a new starting point.

[00:06:24]It provides a solid underlying guarantee for the smooth advancement of the second migration, the healthy operation of referral mining rewards and the implementation of more practical functions in the future. The reason we set the deadline on April 27th is not to put pressure on anyone, but to allow the entire network to move forward in a unified, orderly, and stable manner. I believe that every pioneer who truly cares about PI and has accompanied it for a long time will understand and actively cooperate with this upgrade because our common goal has never been short-term excitement, but to build together a long-term healthy public chain ecosystem that truly belongs to ordinary people. Closing remarks and gratitude. Dear pioneers, the successful completion of the protocol 22 upgrade requires the serious execution of every node operator and the understanding and support of all pioneers. I especially want to say thank you to all node operators. It is because of your day and night duty and timely upgrades that the Pi mainet can remain stable. I also thank every ordinary pioneer for your patience and cooperation. Every contribution you make is the greatest driving force for Pi's steady progress.

[00:07:36]The future of Pi is bright because of all of you. Let us continue to join hands, complete the protocol 22 upgrade well and build the PI mainet to be safer, more stable and more trustworthy.
