Frequently Asked Questions
Zero-Knowledge Virtual Machines (zkVMs) FAQ
What is a Zero-Knowledge Virtual Machine (zkVM)?
A Zero-Knowledge Virtual Machine (zkVM) is a type of virtual machine that enables the execution of computations on encrypted data without decrypting it. This means that the computation is performed without revealing any information about the underlying data, thereby maintaining the confidentiality and integrity of the data.
How does a zkVM work?
A zkVM works by using advanced cryptographic techniques, such as homomorphic encryption and zero-knowledge proofs, to enable computations on encrypted data. Here’s a high-level overview of the process:
- Data Encryption: The data to be computed on is encrypted using a secure encryption algorithm.
- zkVM Compilation: The computation to be performed on the encrypted data is compiled into a zkVM bytecode.
- Execution: The zkVM executes the bytecode on the encrypted data, without decrypting it.
- Verification: The output of the computation is verified using zero-knowledge proofs, ensuring that the computation was performed correctly without revealing any information about the underlying data.
What are the benefits of zkVMs?
zkVMs offer several benefits, including:
- Confidentiality: zkVMs ensure that the data remains confidential throughout the computation process.
