How is zkEVM different from zk-rollups? What do they mean?

The Ethereum Virtual Machine does not support zero-knowledge proofs by default. zkEVM is designed to ensure the continuity of the Ethereum state while providing proof that all information is correct. In this way, many people have begun to know zkEVM, but they don’t know what zkEVM means? zkEVM (Zero-Knowledge Ethereum Virtual Machine) is an Ethereum state machine that executes smart contracts in a manner compatible with Zero-Knowledge Proof (ZKP) technology, designed to ensure the continuity of the Ethereum state while providing all information correct To prove it, the editor below will give you a comprehensive introduction to zkEVM.

#What does zkEVM mean?

zkEVM is a virtual machine compatible with zero-knowledge proof computing and used to execute smart contracts. It is built on Ethereum and processes, stacks and forwards transactions to the Ethereum mainnet. This aggregation processing method is able to efficiently handle large loads from the Ethereum network, allowing for cheaper and faster transactions.

zkEVM achieves its goal by replicating the Ethereum environment as a zero-knowledge summary. It first reads the initial state and calculates all transactions, then outputs the new updated state and the corresponding zero-knowledge proof. This proof is submitted to the verifier smart contract, which verifies the validity of the transaction by verifying the correctness of the initial state and the new state without having to verify all transactions one by one.

Since zkEVM is built on the Ethereum Virtual Machine, it allows developers to easily migrate Ethereum DApps and smart contracts to zkEVM without implementing zero-knowledge proofs. In other words, zkEVM is able to support zero-knowledge proof smart contract execution, including token exchange and payment functions that were not previously supported.

Due to the compatibility features of the Ethereum Virtual Machine, developers can leverage existing Ethereum Virtual Machine tools and the programming language Solidity to create new products while benefiting from the enhanced security provided by zkEVM. Users will also benefit from this, as they can continue to use the same DApps and familiar tools with double the security and privacy protection.

What is the difference between zkEVM and zk-rollups?

One of the main differences between zk-rollups and zkEVMs is their different design goals. Focused on scalability, zk-rollup allows large volumes of transactions to be processed off-chain while still maintaining the security and integrity of the Ethereum main chain. The advantage of this method is that it can greatly improve transaction throughput, reduce transaction fees, and reduce the burden on the Ethereum main chain. In contrast, zkEVM focuses on privacy protection. It allows the execution of smart contracts in a privacy-preserving manner, making it possible to create private, confidential transactions on the Ethereum platform. The advantage of this approach is that it protects users’ privacy, allowing them to conduct blockchain transactions without exposing transaction details. In general, zk-rollups and zkEVMs are solutions proposed to solve the scalability and privacy issues of Ethereum, but their specific implementation and application

zk-rollup and zkEVM are Ethereum significant innovations that can improve Ethereum’s scalability and privacy. These innovations are expected to greatly enhance the functionality of the Ethereum platform, making it more suitable for a wide range of application scenarios.
