ZKsync Opens Prividium Core Code Under Apache 2.0

Matter Labs announced on Sept. 8 that it has made the core code for Prividium, its privacy-focused stack, available under the Apache 2.0 open-source license. The company framed the move as opening the foundational components of Prividium for broader review and reuse while keeping certain higher-level tools and enterprise features under commercial terms.

According to Matter Labs, Germany’s central bank, the Bundesbank, is testing a self-hosted deployment of the software. The reported trial suggests an institutional interest in running Prividium in environments controlled by the user rather than relying on hosted services.

The release establishes a dual approach: community-accessible core code that can be adopted and inspected under a permissive open-source license, alongside commercial enterprise tooling that remains proprietary. Matter Labs says this split preserves commercial opportunities while making core innovations publicly available.

Beyond the licensing change and the Bundesbank trial, Matter Labs has not been reported to have altered the commercial status of its enterprise offerings. The company’s announcement emphasizes the availability of the core code under Apache 2.0 and reiterates that enterprise-grade tools will continue to be offered commercially.
