ZKsync Unveiled Prividium — “The Bank Stack of Ethereum” for the Enterprise Segment

• ZKsync has launched Prividium, a ZK blockchain.
• According to the team, it is preparing Ethereum for a mass influx of banks in 2026.
• The new institutional infrastructure offers privacy, AML and KYC compliance, and native cross-chain interoperability.

The ZKsync team has unveiled Prividium — a new ZK blockchain for institutions, positioned as Ethereum’s “bank stack” and a key piece of infrastructure for large players to enter blockchain at scale in 2026. 

The project stresses that “2026 will be the year of institutional adoption at scale,” and that Prividium delivers user-level privacy, access control, regulatory compliance, cross-chain connectivity with Ethereum, and a security level comparable to the network’s base layer.

Prividium’s key feature is combining private transaction execution with public verifiability of outcomes. All activity — transactions, counterparties, and balances — is executed privately within the operator’s infrastructure, minimizing the risk of data leaks. 

At the same time, each batch of transactions is accompanied by zero-knowledge proofs (ZK proofs) that confirm the correctness of computations “without revealing raw data.”

Transaction finality is achieved by anchoring ZK proofs on the Ethereum network, providing “the strongest available security guarantees.” Regulators, partners, or auditors can receive only the information they are authorized to access, thanks to a controlled data disclosure mechanism.

Prividium combines a role-based access model with ZK proofs, making anti-money laundering (AML) requirements and know-your-customer (KYC) procedures both enforceable and verifiable. 

Granular permissions define who can deploy smart contracts, interact with them, or view data. 

Selective disclosure supports bytecode verification, sanctions lists, and proof of reserves or token circulation “on demand.” This way, regulatory compliance can be demonstrated without revealing sensitive business information.

According to the statement, Prividium operators gain full control over governance and transaction ordering. A single operator can directly enforce policies, while independent validators — optionally — can provide additional confirmation for each batch of transactions. 

The platform supports customization — from choosing a custom gas token to a fully gasless mode for users. 

Horizontal scalability makes it possible to run multiple Prividium instances in parallel and reach any required level of throughput.

Prividium connects natively to Ethereum and the ZKsync ecosystem via ZKsync Connect. Assets and data are transferred without bridges or intermediaries, improving capital efficiency and reducing risks. New networks can be connected “in minutes, not months,” simplifying the scaling of enterprise solutions.

Unlike permissioned ledgers such as R3 Corda or Besu, where all consortium participants can see the data, Prividium provides ledger-level privacy with selective access.

Compared with public blockchains — Ethereum, Solana, or Arbitrum — the solution offers privacy and policy-driven execution, while still preserving public verifiability via Ethereum.

ZKsync noted that Prividium paves the way for new crypto-finance use cases: 

• fast, regulated cross-border payments between financial institutions
• the full lifecycle of digital assets
• tokenized markets with verified participants
• secure cross-chain financial products
• as well as intraday liquidity and secured financing tools

As a reminder, the ZKsync team recently announced the shutdown of ZKsync Lite in 2026.
