- The 21.2 → 22.1 upgrade deadline is TODAY — April 27, 2026 — node operators who have not yet upgraded risk Mainnet disconnection.
- Do NOT upgrade all nodes at once — divert traffic to other nodes or point to https://api.mainnet.minepi.com during the process.
- Pi Network's upgrade roadmap now extends to Protocol 26.0 in June 2026 — five major milestones across a 10-week window.
- Protocol 23.0 deadline has moved earlier to May 11, 2026 — one week ahead of the previously announced May 18 date.
The clock is ticking. Pi Network’s Protocol 22.1 upgrade deadline arrives today — April 27, 2026 — and every node operator who has not yet completed the migration from v21.2 to v22.1 must act immediately. The Pi Core Team activated this upgrade step on April 17, marking the fifth consecutive protocol migration in Pi Network’s carefully sequenced mainnet rollout. Nodes that fail to upgrade today will be disconnected from the Pi Mainnet entirely.
As we covered in our Protocol 21.2 deadline guide, this upgrade is part of a critical dependency chain — each step building directly on the last, with no room to skip. And as detailed in our Protocol 22.1 activation report, this announcement also came with a significantly expanded roadmap — now extending all the way through Protocol 26.0 in late June 2026.
Full Upgrade Status — April 27, 2026
Here is the complete and updated protocol upgrade roadmap as of today:
Important: The Protocol 23.0 deadline has moved from May 18 to May 11, 2026 — one week earlier than previously announced. Update your planning accordingly. Four entirely new upgrade steps — Protocols 23.0, 24.1, 25.1, and 26.0 — have also been added to the roadmap, signaling an accelerating development pace heading into summer 2026.
Why Today’s Deadline Is Critical
Every protocol upgrade in Pi Network’s sequential rollout builds directly on the previous one, creating a strict dependency chain. Missing a step can require a full node resynchronization to catch up. Nodes that fail to upgrade by today’s April 27 deadline risk:
Mainnet disconnection — Nodes still running v21.2 after the deadline will be cut off from Pi Mainnet entirely — unable to process transactions, validate blocks, or participate in network consensus.
Loss of node rewards — Disconnected nodes cannot earn rewards during their offline period, creating a direct financial cost for operators who delay.
Resynchronization requirement — Nodes that miss the deadline may need a full resync to rejoin the network — a significantly more time-consuming process than the simple upgrade available right now.
Network-wide impact — Every node stuck on an outdated protocol version reduces Pi Mainnet’s overall security and performance during the transition window.
Protocol 22.1 — Technical Upgrade Details
The 21.2 → 22.1 upgrade is one of the most straightforward and fastest in the current sequence. Key technical specs:
- Docker Image:
pinetwork/pi-node-docker:organization_mainnet-v1.0-p22.1 - Release Notes:
https://github.com/PiCoreTeam/pi-node-docker/releases/tag/organization_mainnet-v1.0-p22.1 - Expected Downtime: Under 5 minutes in most cases — the fastest upgrade in the current sequence. In rare cases restarts may take longer — allow them to finish without interruption.
- Migration Type: Internal data migrations — quick and automated. No manual data handling required.
How to Complete the Upgrade Right Now
Critical reminder before starting: Do NOT upgrade all your nodes simultaneously. Divert traffic to other nodes or point to
https://api.mainnet.minepi.comduring the upgrade to maintain network stability.
Method 1 — Pi Desktop (Windows and macOS) — Simplest
No manual steps required. Simply restart your Pi Node via Pi Desktop and the upgrade will trigger automatically. This is the fastest and easiest upgrade path — ideal for operators running the desktop client.
Method 2 — Linux Node CLI — Recommended
If auto-update is enabled: No action required — the upgrade processes automatically.
If auto-update is disabled, run:
pi-node update-protocolMonitor progress with:
watch pi-node statusUpgrade is complete when your node shows “Synced” and ingest_latest_ledger matches the network. Verify by running:
curl http://localhost:31401Compare against: https://api.mainnet.minepi.com
Method 3 — Self-Managed Docker
Update your docker-compose.yml with the new image:
pinetwork/pi-node-docker:organization_mainnet-v1.0-p22.1Then run:
docker-compose up -dExpected downtime for Docker operators is typically under 5 minutes.
What Comes Next — The Road to Protocol 26.0
Completing today’s Protocol 22.1 upgrade puts node operators in position for four remaining milestones in Pi Network’s current upgrade sequence:
22.1 → 23.0 — Deadline May 11, 2026: The most significant near-term milestone. Protocol 23 is widely expected to introduce broader smart contract functionality — moving Pi’s capabilities from Testnet experimentation to Mainnet readiness. As we covered in our Pi Network RPC server launch analysis, this upgrade is the direct enabler of the full developer ecosystem Pi has been building toward. Wait for official Pi Core Team activation — do NOT start this upgrade early.
23.0 → 24.1 — Deadline May 25, 2026: Details TBD. Monitor @PiCoreTeam on X and minepi.com/blog for activation announcements.
24.1 → 25.1 — Deadline June 8, 2026: Details TBD.
25.1 → 26.0 — Deadline June 22, 2026: The final step in the currently disclosed roadmap — completing Pi Network’s full 2026 protocol upgrade sequence.
Five major protocol milestones across a 10-week window from May through late June 2026 represents the most infrastructure-dense period in Pi Network’s history.
How This Connects to Pi’s Broader 2026 Momentum
Today’s upgrade deadline is not happening in isolation. Alongside the protocol upgrade sequence, Pi’s ecosystem is delivering across multiple fronts simultaneously:
- The Pi Launchpad Testnet strong Pioneer participation.
- Second migrations have brought referral bonuses on-chain for over 119,000 Pioneers.
- The public Testnet RPC server has opened Pi’s infrastructure to external developers for the first time — a direct prerequisite for the Protocol 23 smart contract launch.
- Protocol 23’s smart contract upgrade will enable the Pi Launchpad Mainnet launch and Pi DEX integration — the real-world utility tools Pi’s ecosystem has been building toward throughout 2026.
Bottom Line
The Protocol 22.1 deadline is today — April 27, 2026. If you are a Pi Network node operator and you have not yet upgraded from v21.2 to v22.1, act now. With under 5 minutes of expected downtime and a straightforward process across all platforms, there is no reason to delay. Every node that stays online and upgraded strengthens Pi Network’s decentralization and keeps the ecosystem on track for its historic Protocol 23 smart contract milestone in May.
Frequently Asked Questions (FAQ)
What is the Pi Network Protocol 22.1 upgrade deadline?
The deadline for the 21.2 → 22.1 protocol upgrade is today — April 27, 2026. Node operators who do not complete the upgrade by this date risk being disconnected from Pi Mainnet entirely.
How long does the Protocol 22.1 upgrade take?
The 22.1 upgrade is one of the fastest in the current sequence — expected downtime is under 5 minutes in most cases. In rare cases, restarts may take slightly longer, but no manual data handling is required.
What happens if I don’t upgrade my Pi node by April 27?
Nodes still running v21.2 after the deadline will be disconnected from Pi Mainnet. This means your node will be unable to process transactions, validate blocks, earn node rewards, or contribute to network consensus until you upgrade and resync.
Can I upgrade all my Pi nodes at the same time?
No. The Pi Core Team explicitly advises against upgrading all nodes simultaneously. Divert traffic to your other nodes or point to https://api.mainnet.minepi.com during the upgrade process to maintain network stability.
How far does Pi Network’s upgrade roadmap extend?
The currently disclosed roadmap extends through Protocol 26.0, with a deadline of June 22, 2026 — covering five major upgrade milestones across a 10-week window from May through late June 2026.
