TL;DR
- Matter Labs open-sourced the permissioning engine of Prividium, its DLT platform for regulated financial institutions.
- The Deutsche Bundesbank, Germany’s central bank, is the first institution to test and deploy Prividium on its own infrastructure.
- The permissioning engine can operate as a standalone component, without requiring a commercial agreement with the developer for its use.
Matter Labs, the development company behind ZKsync, open-sourced the permissioning engine of Prividium, its distributed ledger technology platform aimed at financial institutions.
The decision allows any institution to run, inspect, and modify the core code from its own environment, without relying exclusively on a commercial vendor. At the same time, the Deutsche Bundesbank became the first institution to test and deploy the open-source permissioning engine within its own infrastructure.
The code release responds to demand from the regulated sector. Alex Gluchowski, CEO of Matter Labs, explained that the most consistent feedback received from regulated institutions indicated that an exclusively commercial core created an unacceptable single-vendor dependency for critical infrastructure. “The ability to run, inspect, and modify the code independently is a prerequisite for adoption,” Gluchowski stated.
Matter Labs and the Bundesbank Send a Signal to the Entire Sector
Prividium’s technical design keeps smart contract and token data within the operator’s environment, while using zero-knowledge proofs to verify the correctness of operations. Several components were already open source beforehand, including the ZKsync OS core, the Atlas sequencer, the Airbender prover, the interoperability contracts, and the block explorer.
Today we announce that Prividium's core, the permissioning engine that governs roles and access, is now open source.

As announced, the permissioning engine will function as a standalone component, allowing an institution to operate a permissioned chain from public code without needing to establish a commercial agreement. Administration tools and integrations with existing systems will remain commercial products.
Matter Labs joins a broader trend. Several central banks and large financial institutions continue to explore settlement infrastructure and tokenization based on blockchain. The Eurosystem is currently working on Pontes, a system designed to connect market DLT platforms with Europe’s TARGET payment services, with an initial launch scheduled for the third quarter of 2026, according to the European Central Bank and the Bundesbank itself.
Matter Labs indicated that it will continue collaborating with the German central bank on the design and testing of the platform.
