PI Network has shared a fresh node update through its official X account. The team said the Mainnet blockchain is moving through Protocol 22. The key deadline is April 27, 2026. All nodes must upgrade to v22.1 before this date.
The official Pi Node page also says the Mainnet protocol upgrade is in progress. It states that every validator must move to v22.1. The latest Node desktop version listed on the page is 0.5.4.
This PI Network News update matters because validators help support the functioning. Crypto news says a validator runs on laptops and desktops. They help validate transactions and support consensus on the shared ledger.
Validators should focus on three points:
Deadline: April 27, 2026
Required version: v22.1
Main action: Nodes should upgrade before the cutoff

Source: Official X Account
Validator uses the Stellar Consensus Protocol. In simple words, validators work through trusted groups. These groups help agree on valid transactions.
This is also linked to Network Mainnet progress. Readers can also check the smart contract release to understand recent technical work around Testnet.
It's not just a normal software change. This shows that the project is still moving through its technical roadmap.
For readers, the main point is simple. Old nodes may not stay aligned after the deadline. That can affect validator participation.
The official page explains that validators support decentralization. It also says users can run Node through a desktop app. This makes participation easier for non-technical users.
This PI Network News story may also draw attention to token sentiment. Upgrade deadlines often create short-term market interest. Still, price movement depends on demand, listings, liquidity, and broader crypto market mood.
After v22.1, the market will watch how smoothly validator operators complete. A clean action can support confidence in Mainnet operations.
The next key question is whether the project can keep moving toward stronger project stability. Investors will also watch future protocol 22 updates, validator activity, and Pi mainnet news.
For now, the message is clear. Validators should complete the action before April 27. That deadline is now the center of this PI Network News update.
Pi Network has given node operators a clear task. Upgrade to v22.1 before April 27, 2026. The update supports wider Mainnet process and keeps nodes aligned with the latest protocol path. For readers and investors, the next signal will be how smoothly the project handles this deadline.
