for us to truly understand what zkEVM is we need to first understand what zero-knowledge proof, well zero-knowledge proof is a type of cryptography that allows you to prove your identity or specific credentials to a third party, without revealing any personal details. Zero-knowledge proof allows you to maintain control over your identity. This means that instead of constantly having to provide personal identification like a driver's license, apps can verify your identity without actually having access to any of your sensitive personal information. With zero-knowledge proof, only the necessary information is provided to prove your eligibility for certain services or compliance with regulations. This reduces the risk of fraud and makes processes such as visa applications, loans, rent agreements, and voting much simpler and more secure.
zkEVM is a Layer 2 scaling solution for Ethereum that uses a technique called Zero-Knowledge (ZK) rollups to improve scalability and reduce the cost of transactions. In zkEVM, transactions are processed off-chain and only the final state is committed to the Ethereum mainchain through cryptographic proofs, which are verified by smart contracts on the main chain.
This means that zkEVM can process a large number of transactions off-chain, without burdening the Ethereum network with high gas fees and congestion. Users can transfer their tokens between addresses, interact with smart contracts, and perform other transactions on zkEVM with low transaction fees and fast confirmation times, similar to those offered by centralized exchanges.
Furthermore, zkEVM ensures that the security of the system is maintained even though the transactions are processed off-chain. This is done by creating cryptographic proofs that ensure the correctness and validity of the transactions before they are committed to the Ethereum mainchain. These proofs are generated by a decentralized network of validators who are incentivized to ensure the security and integrity of the zkSync system.
Overall, zkSync provides a secure and low-cost way to scale Ethereum, while still maintaining the same level of security as the Ethereum main chain.
