TL;DR:

The architecture integrates Prividium as a private execution layer and Phylax for deterministic risk controls.

The system enables the native issuance of tokenized deposits, stablecoins, and Real-World Assets (RWA) with total privacy.

Thanks to Zero-Knowledge (ZK) proofs, entities achieve cryptographic integrity without exposing sensitive data.

The global banking sector has moved past debating the importance of blockchain to focus on the infrastructure necessary for its implementation. In this context, ZKsync and Phylax have presented “Bank Stack,” an innovative on-chain financial architecture for institutions anchored in the security of Ethereum.

This innovation is designed to resolve structural issues of fragmentation and high compliance costs that traditional entities must face. By linking the mainnet with Prividium, banks can execute confidential transactions while maintaining interoperability with the global market.

Privacy and Operational Security: The Pillars of the Bank Stack

Unlike other products, this architecture is divided into three integrated planes covering everything from the blockchain platform to governance services. On one hand, Prividium serves as the institutional transaction layer, allowing for predictable performance and rapid deployment without rebuilding infrastructure from scratch.

On the other hand, Phylax introduces execution-time controls that act as “circuit breakers” to prevent catastrophic losses. These mechanisms allow for the establishment of limits and security policies that are executed deterministically, preventing anomalous transactions from being executed on-chain.

Furthermore, the proposal includes a native identity and compliance layer that moves KYC/AML regulations directly into the logic of the assets. This transforms regulatory compliance from an operational burden into an architectural guarantee, facilitating real-time auditing and reporting.

In summary, the Bank Stack marks the beginning of an era where institutional finance operates in a shared and programmable manner. With the ability to settle flows instantly and manage risks robustly, ZKsync and Phylax are building the rails of the financial future on Ethereum.
