ZK-rollups and Optimistic rollups are both Layer 2 scaling solutions that aim to increase transaction throughput and speed by moving transactions off-chain12. However, they differ in their transaction verification and dispute handling mechanisms12. Optimistic Rollups: They operate under the assumption that all transactions are valid by default unless proven otherwise12. They use a fraud-proving scheme, […]

A zero-knowledge proof is a concept in cryptography where one party (the prover) can prove to another party (the verifier) that a given statement is true, without conveying any information beyond the mere fact of the statement’s truth1. This means they don’t prove something with as much certainty as simply revealing the entire information would2. […]

A zkEVM rollup is a zero-knowledge Ethereum Virtual Machine1. It aims to replicate the Ethereum environment as a rollup, allowing developers to build on it just like they would on Ethereum1. It is an EVM-compatible rollup that is secured by a Zero-Knowledge Proof (ZKP), giving it the enhanced functionality of some of the Optimistic Rollup […]
