COTI pushed a planned upgrade to its mainnet on October 19, 2025, at 12:00 PM UTC, a move the project says will make the network faster, stronger and more resilient. The update is being framed as a careful, engineering-first step forward rather than a flashy new feature, the kind of infrastructure work that quietly matters once systems are under real-world strain.
The team made a point of reassuring users: the upgrade runs automatically and requires no action from token holders or end users, and node operators had already moved to the latest release to smooth the transition. In short, COTI expects wallets, nodes and other participants to switch over seamlessly without any disruption to assets or day-to-day use.
Faster, More Resilient, Privacy-Ready
Dubbed “Hydrogen,” this release is the network’s first formal hard fork and bundles a set of protocol-level changes aimed at long-term maintainability, cryptographic security and operational stability. Rather than being a grab-bag of optimizations, Hydrogen reads like a targeted refactor of core pieces of the stack meant to strengthen the platform for enterprise and developer use.
One of the focal points of the upgrade is MPC, Multi-Party Computation, where engineers implemented safer file-handling, reinforced the randomness that underpins cryptographic operations, and tightened memory hygiene so sensitive data is wiped clean during cleanup. Connection handling was also hardened to behave more predictably under high concurrency, a practical improvement for privacy-first, enterprise-grade deployments.
On the execution side, COTI updated gcEVM with stricter protocol validation, improved error handling during opcode execution, and more efficient block processing. Those changes are meant to bring nodes to a more consistent execution standard and reduce surprises for developers and integrators running complex workloads on the network.
COTI frames Hydrogen as a building block: shoring up the architecture today to make broader adoption, greater interoperability and privacy-preserving, high-performance applications easier to build tomorrow. The message from the team is straightforward: meaningful progress doesn’t have to be disruptive; when done deliberately and audited, upgrades can improve trust without upending the user experience.
