@zksync recently held a workshop for major financial institutions to introduce Prividium, its institutional-grade Layer 2 solution. The event brought together global heavyweights including @Citi, @DeutscheBank, @Mastercard, and the Central Bank of France.

During the workshop, zkSync presented the following key points: 1. Institutional-grade privacy and integrity Prividium uses ZK proofs to ensure computational integrity while keeping data private — an ideal setup for financial institutions.

2. High scalability with the Atlas upgrade The recent Atlas upgrade enables up to 15,000 TPS and 0.2-second block times, significantly improving throughput.

3. Seamless interoperability Through its interoperability solution, Prividium allows smooth asset transfers and contract calls between private chains or between private and public chains.

4. Low-cost ZK proofs with Airbender Using Airbender, ZK proofs can be generated at a cost as low as $0.0001 per transaction. Compliance at the chain level: Institutions can implement KYC and AML rules directly at the chain layer.

While Prividium promises strong privacy, it raises an interesting question of how seamless interoperability with public chains can be achieved under such constraints. The true test will come once it’s deployed in production, where developers can properly assess its experience.
