Matter Labs CEO Alex Gluchowski on open source as the answer to vendor dependency in financial infrastructure, and a central bank running public code.

We're excited to announce that $ZK, the native token of ZKsync — the institutional privacy and settlement network on Ethereum — is now available on Revolut, Europe's largest fintech.
With over 70 million users globally, Revolut is one of the most trusted digital banking platforms in the world. The availability brings $ZK directly into the hands of 15M retail users across the UK and EEA, enabling them to access $ZK with 0% FX fees, seamless fiat onramps, within the convenience of a regulated finance app.
This moment reflects a broader shift already underway.
Across the financial system, institutions are moving onchain. Not as an experiment, but as a transition toward more efficient, programmable, and globally interoperable finance. ZKsync has been building for this shift, enabling private execution, selective disclosure, and settlement anchored to Ethereum, with strong adoption already underway. As the $100 trillion global banking system evolves toward programmable settlement, $ZK underpins and captures the economic activity of this emerging network.
The availability of $ZK on Revolut expands access to this network connecting retail users to the same underlying infrastructure that institutions are rapidly adopting.

Prividium Core is now open source under Apache 2.0: one app and six packages, designed to run against ZKsync OS as a working permissioned chain.

Matter Labs is open-sourcing the Prividium permissioning engine, so institutions can run a permissioned chain from public code, in their own environment.
