Due to its popularity and the number of decentralized apps (dApps), Ethereum has experienced network congestion. This move has limited scalability, high fees, and slow transactions. Layer 2 (L2) protocols, which are platforms that operate on top of the underlying blockchain, have been one answer to these challenges. One sort of L2 solution is zero-knowledge rollups, which are aimed to provide improved transaction speeds and cheap costs. The other top solution is optimistic rollups parallel to the main Ethereum chain on layer 2. This feature can improve the scalability of the network by not requiring any computation. Instead, after a transaction, it will propose a new state to Mainnet. The main issue with Ethereum is how developers and users will choose the most advanced technology for their app. Convenience usually wins unless the technology is better. This article will discuss how optimistic and zero-knowledge rollups transform and improve network performance. Let’s dive in: What are Rollups? A rollup is an Ethereum-based scaling solution that allows users to perform transactions outside the network’s Layer 1. It will enable the key to maintain its security while scaling the network. Because just a portion of the data from rollup transactions must fit within Ethereum blocks, moving transaction execution off-chain enables a more significant number of transactions to be executed. Rollup transactions are processed on an entirely...
