# What are ZKVMs?

### What are zkVMs?

Zero-knowledge virtual machines (zkVMs) revolutionize blockchain-based computation. Combining zero-knowledge proofs (ZKPs) with virtual machines, zkVMs create a secure, efficient, and privacy-focused environment for executing arbitrary code, including smart contracts and decentralized applications (dApps).

Unlike traditional virtual machines, zkVM outputs can be verified without computations without access to inputs. In a ZK-based network, this can make certain previously necessary consensus mechanisms (such as re-executing transactions) redundant. 

### Unleashing the Potential of zkVMs

Verifiable computation with zero-knowledge proofs opens new possibilities for privacy-preserving computation in finance, healthcare, supply chain, and more.

In the context of blockchains and decentralized applications, zkVMs offer a game-changing approach to ensure data confidentiality, integrity, and efficiency. Smart contracts deployed on zkVMs securely handle sensitive information without compromising user privacy, fostering greater trust and wider adoption.
