Institutions want to build on Ethereum and leverage its incorruptibility, hard finality, and global liquidity. But many financial use-cases can’t be run on a chain where everything is public by default. Here’s how Prividium extends Ethereum for enterprises:

Used by millions and securing billions in capital, Ethereum has established itself as the definitive network for decentralized apps. For financial institutions, using it as a settlement backbone means tapping into a shared source of truth that no single entity controls.

And with the EVM as the de-facto standard for production-grade web3 applications, Ethereum also brings a mature ecosystem of tools, libraries, frameworks, and infra that enterprises can rely on. The kind of ecosystem gravity no alternative system can match.

Most critically for financial use-cases, Ethereum is incorruptible. Incorruptibility means no party can violate the rules under any circumstances. Ethereum achieves this as participants verify every transaction publicly, enforcing the correctness of the network.

But for some institutional use-cases, a public data model is a non-starter. You can’t expose positions, cashflows, or counterparties to the entire world and still meet fiduciary, competitive, and regulatory constraints. Privacy isn’t “nice to have”, it’s mandatory.

This pushed some institutions towards using private or permissioned ledgers, but these systems are restricted islands, isolated from the global economy and often dependent on privileged or trusted actors.

And so institutions were left with hard trade-offs: → Public blockchains (verifiable but exposed) → Private ledgers (confidential but isolated) Both broke something essential, privacy or interoperability. Neither of these two model works for regulated capital markets.

That’s the gap Prividium fills. Private and interoperable enterprise blockchains, secured by ZK proofs and anchored to Ethereum. Customizable for different use-cases, Prividiums keep data confidential, let regulators verify compliance, and connect to public liquidity.

Each Prividium runs inside an institution’s own environment → cloud or on-prem. > Transactions execute privately. > Balances and data never leave the operator’s systems. > Every batch generates a ZK proof, verified on Ethereum. Private execution, public verification.

By anchoring private execution to Ethereum’s public settlement layer, Prividiums move beyond the old “public vs private” trade-off. Institutions can now build private systems that are provably correct, publicly verifiable, and fully connected to Ethereum’s ecosystem.

So, how is visibility defined in a Prividium? Each participant only sees what they’re meant to. > Public → only sees proofs on Ethereum > System operator → role-based visibility > Regulators → selective disclosure (only the fields they’re authorized to view)

But privacy alone isn’t enough. Institutions need their private systems to talk to each other. That’s why Prividiums are interoperable by design. They connect natively to Ethereum and other ZKsync chains (both public and private), without relying on third‑party mechanisms.

This architecture unlocks: > Near real-time connectivity replacing T+2. Capital moves more efficiently > Privacy with connectivity to Ethereum’s deep pubic liquidity > ZK proofs for credible transparency, and cryptographic compliance

ZK proofs can make private systems incorruptible. In simple terms, they allow one party to prove a statement is true without revealing any of the underlying details of the statement.

Every Prividium proves the correctness of its private state with ZK. This is what makes privacy practical, extending Ethereum’s verifiability and incorruptibility.

This is a critically important point. As an example, a single system that can illegitimately mint tokens would be a systemic risk, able to compromise every interconnected system.

ZK is the only approach that can enforce integrity across private systems without relying on a trusted or curated network.

Under the hood, Prividiums run on the ZK Stack. Powered by Airbender, the world’s most performant open-source RISC-V proof system, and upgraded through Atlas, it’s enterprise-ready: thousands of TPS, sub-cent costs, ZK-verified.

We’re already seeing the first Prividium production deployment: @Memento_Bc, a compliance-focused chain built with @DeutscheBank to bring fund servicing and reconciliation onchain. Many more chains are on testnet already.
