Neutral and transparent governance of the Global Synchronizer for the @CantonNetwork

[Canton Foundation @CantonFdn]

May Ecosystem Update 👀

◽ CIP-0116: Featured App Locking. A new governance framework requiring Featured Apps to lock 5M CC (or 25M CC for higher reward tiers), with a 30-day compliance window and 60-day unlock period.

◽ 166 new validator operators approved, continuing to expand the decentralized infrastructure powering @CantonNetwork.

◽ Unified developer documentation launched. Role-based learning paths, consolidated SDKs and tooling references, and a built-in AI assistant to help builders navigate the full development stack.

◽ @OneSwapCC approved as a Featured App, joining the growing set of applications building on Canton.

◽ The Canton Foundation team attended @SEABWOfficial in Bangkok, connecting with builders and institutions across the APAC region.

◽ First Canton Builder Office Hours completed, opening a direct line between the Foundation and developers building on the network.

Six milestones in just one month. The Canton Network ecosystem continues to grow, govern, and build.

ICYMI: @0xBlockBooster joined the Canton Foundation as a member, alongside other leading global institutions.

As a member, BlockBooster will participate in Foundation governance, contribute to ecosystem development, and expand its on-chain asset management footprint across private credit, tokenized funds, and other real-world asset categories on @CantonNetwork.

When asset managers join the same governance table as the world's largest custodians and settlement systems, it signals where institutional infrastructure is heading.

If you're building at @ETHGlobal, join our @CantonNetwork Workshop w/ @JPandya26 tomorrow at 3 PM EST.

If you're considering the Canton Foundation bounty, this is where you start.

The workshop covers Canton's architecture, the developer tooling, and how to deploy on DevNet before you write a single line of code.

Validator Resources:

Here is what validators need to prepare for Canton Protocol 35.

Minimum Splice version: 0.6.5. If you are not running this version, your node will not participate in the Protocol 35 upgrade. Confirm your version now.

The upgrade uses a Logical Synchronizer mechanism. The old and new protocol versions coexist during the transition. Transactions continue processing. Once all validators confirm, the cutover happens seamlessly.

Validators do not need to coordinate downtime. But they do need to be on the correct Splice version before the TestNet LSU window opens.

CIP-0117 has been approved: Logical Synchronizers.

Protocol upgrades on @CantonNetwork will no longer require coordinated multi-hour network halts. Logical Synchronizers reduce upgrade downtime from hours to seconds.

How it works: A successor synchronizer spins up alongside the existing one. Validators upgrade their binaries at their own pace before the scheduled window. At upgrade time, the network cuts over automatically. No coordinated shutdown. No migration dumps. No manual recovery steps.

Why this matters: Previous upgrades (CIP-0062, CIP-0089) required 90 minutes to 3 hours of downtime, a live coordination call across all Super Validator operators, and explicit action from every validator. As the network scales, that pattern breaks. CIP-0117 moves coordination on-chain, automates the validator-side upgrade, and makes protocol evolution a routine operation.

Validator history is fully preserved. Applications see a continuous transaction stream. Application developers do not need to take any action.

First Logical Synchronizer Upgrade schedule:

→ DevNet: June 10
→ TestNet: June 17
→ MainNet: June 27

Minimum Splice version: 0.6.5

Approved June 5, 2026.
