Why has Matter Labs open-sourced the Prividium engine?

Matter Labs has open-sourced Prividium’s permissioning engine so financial institutions can run, inspect and modify the core software themselves.

What is Prividium used for?

Prividium is Matter Labs’ distributed-ledger platform for financial institutions, designed to keep smart-contract and token data within an operator’s environment.

How is Deutsche Bundesbank testing Prividium?

Deutsche Bundesbank is the first institution testing and deploying Prividium’s open-source permissioning engine within its own infrastructure.

What does the open-source Prividium engine allow?

The Prividium engine allows institutions to operate permissioned blockchains from public code without relying on a commercial agreement for the core permissioning software.

Why does Matter Labs use zero-knowledge proofs in Prividium?

Matter Labs uses zero-knowledge proofs in Prividium to verify correctness while keeping smart-contract and token data inside the institution’s own environment.

Matter Labs open-sources Prividium engine for banks

Matter Labs has open-sourced Prividium’s permissioning engine for financial institutions.
Deutsche Bundesbank has become the first institution to test and deploy the engine.
The release lets institutions run and modify the core software themselves.

Matter Labs, the developer behind ZKsync, has open-sourced the permissioning engine for its Prividium blockchain platform.

Deutsche Bundesbank has become the first institution to test and deploy the engine within its own infrastructure, Matter Labs said.

“The ability to run, inspect and modify the code independently is a precondition for adoption,” said Alex Gluchowski, Matter Labs CEO.

The release allows institutions to operate permissioned blockchains from public code while keeping smart-contract and token data within their own environments.

Matter Labs is privately held, so there was no public share-price reaction following the announcement, which was made on September 8.

The Prividium engine uses zero-knowledge proofs to verify network activity while allowing institutions to control their own infrastructure.

Matter Labs said the engine will operate as a standalone component, while administration tools and institutional integrations will remain commercial products.
