Finality on Ethereum

Finality on Ethereum

Proofs are anchored to Ethereum, providing transaction finality with the strongest available security guarantees.

Prividium™ is a full ZK-based blockchain that keeps data private within your infrastructure.

Designed for enterprises, Prividium™ offers user-level privacy, compliance, cross-chain connectivity, and Ethereum-grade security out of the box.

Privacy with public proofs

Prividium™ ensures that sensitive data never leaves your infrastructure. Transactions, counterparties, and balances remain private, while ZK proofs certify correctness without exposing raw information. This eliminates the risk of data leakage and ensures regulators, partners, and auditors can verify outcomes independently. Finality on Ethereum combines privacy with strong security guarantees, making the system private yet publicly verifiable.

Prividium built-in compliance with role-based access controls and selective disclosure

Built-in compliance

Prividium™ combines role-based access controls with ZK proofs to make requirements such as AML and KYC enforceable and verifiable. Granular permissions allow only authorized parties to deploy contracts, interact with them, or view data. Selective disclosure supports bytecode verification, sanctions checks, and proof of reserves or circulating supply on demand. Compliance can be demonstrated without exposing confidential business data, aligning blockchain operations with regulatory expectations.

Enterprise control with scale

Prividium™ gives operators full authority over governance and transaction ordering. A single operator can enforce policies directly, while independent validators can optionally attest to each batch for added protection. Enterprises can also customize the chain, from defining a custom gas token to operating in a fully gasless mode for seamless user experience. The platform is designed for horizontal scalability, allowing multiple Prividium™ instances to run in parallel and meet any level of throughput demand.

Prividium direct connectivity to Ethereum via ZKsync Connect without bridges

Direct connectivity

Prividium™ chains connect natively to Ethereum and the ZKsync ecosystem via ZKsync Connect, providing enterprises with seamless connectivity. Assets and information move seamlessly without bridges or intermediaries, improving capital efficiency and reducing risk. Transactions inherit Ethereum finality, while new chains can be onboarded in minutes rather than months, eliminating governance overhead and simplifying enterprise expansion.

Prividium™ enables new use cases

Faster, compliant global payments

Cross-border payments between regulated entities

Traditional cross-border settlements take days, rely on intermediaries, and expose sensitive data. With Prividium™, regulated institutions can transfer value directly between one another. Transactions settle in minutes, compliance checks are enforced on chain, and data stays private, removing costly intermediaries and delays.

Digital asset issuance and lifecycle management on Prividium

Full lifecycle for digital assets

Digital asset issuance and lifecycle management

Issue, distribute, and manage digital securities or tokenized assets with end-to-end governance. From creation and onboarding investors through dividends, transfers, and redemption, Prividium™ enforces compliance automatically. Every action is auditable and anchored to Ethereum while operational details remain confidential.

Compliant markets, verified participants

KYC-anchored tokenized markets

Open new liquidity channels without regulatory risk. Prividium™ enables marketplaces where every participant is identity verified (KYC/AML) but trades are still peer to peer. This reduces counterparty risk, ensures compliance, and allows institutions to safely unlock liquidity across tokenized assets.

Atomic swaps and cross-chain finance between institutions

Secure cross-chain financial products

Atomic swaps and cross-chain finance between institutions

Institutions can move value instantly across chains without intermediaries. Prividium™ supports atomic swaps, ensuring both sides of a transaction succeed or none at all. Combined with interoperability in the Elastic Network, banks and enterprises can build new cross-border settlement systems and financial instruments that work across multiple chains securely and privately.

Real-time intraday liquidity

Intraday repo and secured financing

Repurchase agreements (repos) are a backbone of institutional funding, but intraday liquidity is constrained by manual processes and batch settlement. Prividium™ enables real-time intraday repo markets where collateral, cash, and settlement all move instantly and privately. Institutions can optimize treasury operations, reduce counterparty exposure, and free up capital throughout the trading day.

ZKsync: The Elastic Network Endgame

Delphi Consulting's institutional accelerator report examines ZKsync's transformation from a single ZK rollup into the Elastic Network — a modular ecosystem of interoperable ZK Chains built on the open-source ZK Stack. The report argues that ZK proof technology is the key to solving blockchain's dual challenge: liquidity fragmentation across 30+ L2s and public chains' inability to meet institutional demands for privacy, compliance, and customization. With $1.19B in total economic value and 13+ new ZK Chains onboarding, ZKsync is positioning across tokenization, gaming, social, and permissioned enterprise use cases.

  • Three-pillar architecture (ZK Router, ZK Gateway, ZK Chains) enables trustless cross-chain interoperability with shared liquidity, ~1s soft confirmations, and no third-party bridge dependencies
  • Enterprise adopters include Deutsche Bank (asset tokenization), Buenos Aires government (digital identity for 3.6M residents), Tradable ($1.7B tokenized private credit), GRVT (regulated hybrid DEX), and Lens (decentralized social media)
  • ZKsync leads all rollups in theoretical throughput at 434 TPS with the second-lowest block time; 2025 roadmap targets 10,000 TPS at $0.0001 per transaction
  • Modular ZK Chain design lets enterprises choose chain type (rollup/validium), data availability, gas token, sequencing model, and permissioned vs. permissionless access — enabling confidentiality with verifiability
  • ZK token (21B supply, ~$687M circulating market cap) serves governance, network fees, and future validator staking; three-body governance model (Token Assembly, Security Council, Guardians) implements separation of powers
The Future of Tokenization: How ZKsync Is Changing the Game

The Future of Tokenization: How ZKsync Is Changing the Game

The Block Research report examines how ZKsync's Elastic Chain architecture is positioned to capture the projected $10–16 trillion tokenized asset market by 2030. The report argues that while tokenization of real-world assets has already surged past $11 billion, the industry has yet to achieve full on-chain issuance and value transfer — and that ZKsync's combination of scalability, customization, confidentiality, security, and native interoperability addresses the key technical and enterprise-readiness blockers preventing that transition.

  • 97% of institutional investors (BNY Mellon/Celent survey) agree tokenization will revolutionize asset management; BCG/ADDX project a $10–16T tokenized asset market by 2030
  • ZKsync's Elastic Chain enables full on-chain issuance by eliminating intermediaries, minimizing counterparty risk, enabling real-time settlement, and improving liquidity through automated smart contracts
  • Modular ZK Stack lets enterprises customize chain type, gas token, data availability, data visibility, accessibility (permissioned/permissionless), sequencing, and consensus — supporting granular compliance and confidentiality requirements
  • Early institutional traction includes Tradable ($500M+ private credit tokenization), Fidelity International ($50M money market fund on ZKsync Era), Deutsche Bank (asset tokenization platform on a ZK Chain), and Buenos Aires government (decentralized digital identity for 3.6M residents)
  • Three remaining adoption blockers identified: regulatory clarity, technological robustness, and enterprise readiness — with the Elastic Chain directly addressing the latter two while positioning enterprises to adapt as regulations evolve

Frequently asked questions

Everything you need to know about Prividium™.

No. Only ZK proofs are posted to Ethereum. These proofs confirm correctness without revealing underlying data or transaction details.

No. Permissioned ledgers depend on consortium trust. Prividium™ uses ZK proofs so every block is automatically verifiable. Trust is built into the math, not the governance model.

ZK proofs guarantee that every block is correct, even if there's only a single sequencer. An operator can see and choose which Prividium™ transactions to include, but they cannot falsify results because invalid blocks will fail verification. This means censorship is possible today, but a malicious or invalid transaction cannot be executed.

Yes. Prividium™ lets regulators verify balances, flows, or specific fields using cryptographic proofs tied to the Ethereum-anchored state. In practice, operators could also provide offchain reports as they do today. The difference is that with Prividium™, regulators have the option to independently verify the data whenever they are ready to adopt the tooling.

Not yet. Today Prividium™ operates with a single sequencer. Decentralized sequencing is on the roadmap, which will allow multiple operators to share responsibility and reduce censorship risk. Each sequencer in that model will see the full data processed on Prividium™.

Add-ons like FHE or mixers only cover certain applications and often add heavy performance costs. They also make data private even from the operator, which creates compliance risks, as seen with mixers. Prividium™ is a full chain architecture with privacy, compliance, and interoperability built in from the base layer, ensuring confidentiality without breaking regulatory requirements.

Traditional bridges rely on third parties and introduce extra trust assumptions. Prividium™ uses Ethereum itself as the trust anchor, enabling native, trust-minimized interoperability without intermediaries. Learn more about interop.

No. The core stack is open source and independently audited. Enterprises can operate it themselves, work with Matter Labs for SLAs and enterprise support, or choose other hosting providers. There is no vendor lock-in.

Each Prividium™ chain sustains 10K+ TPS. Enterprises can deploy multiple chains in parallel to scale throughput as needed, without hitting a performance ceiling. These chains communicate seamlessly through native interoperability, so assets and data can move across them as if on a single network, while preserving privacy, compliance, and Ethereum-grade security.
