We are pleased to announce that on October 19, 2025, at 12:00 PM UTC, COTI will undergo a network upgrade, marking a pivotal milestone in the network’s continued evolution.

The upgrade will occur automatically, requiring no action from users. All network participants, wallets, and nodes will transition seamlessly. With each release, we strengthen our infrastructure, guided not just by technical ambition but by the needs of our ecosystem: developers, enterprise partners, and users alike.

What’s included in the upgrade?

This upgrade includes significant protocol-level enhancements and introduces the first formal hard fork of the COTI network, known as ‘Hydrogen’. It includes a range of backend improvements focused on stability, cryptographic security, and long-term maintainability.

Following a comprehensive audit earlier this year, we’ve implemented critical refinements to both the MPC (Multi-Party Computation) and gcEVM components. These changes ensure COTI continues to lead with private, enterprise-ready infrastructure that’s resilient under load, efficient in execution, and secure at the core.

For instance, within MPC, we’ve introduced safer file-handling mechanisms, reinforced the randomness used in cryptographic operations, and improved memory hygiene by ensuring sensitive data is wiped from memory during cleanup. Enhancements to connection handling under high-concurrency conditions also make the network more robust in real-world usage scenarios.

On the gcEVM side, this upgrade tightens protocol validation, improves error-handling within opcode execution, and streamlines block processing. In fact, it brings all network participants under a more secure, consistent execution standard. This isn’t just an optimization, it’s a foundational shift that increases trust and reliability across the ecosystem.

No Action Required

As with previous upgrades, end users and token holders don’t need to take any action. Your assets will remain completely secure, with no anticipated disruption to network operations. All Node operators have already upgraded to the latest software release ahead of time.

Looking Forward

We are one step closer to realizing the long-term vision of the COTI protocol. By reinforcing the underlying architecture, we’re setting the foundation for broader adoption, increased interoperability, and a more reliable ecosystem for privacy-preserving, high-performance applications.

We will continue to iterate, refine, and ship improvements that align with our technology, vision, and the dynamic needs of our partners. The upgrade reminds us that meaningful evolution doesn’t have to be disruptive, it can be deliberate, forward-looking, and built to last.

Stay tuned for further updates, and as always,
Stay COTI.
