Ethereum Rollups

📜 TL;DR:

  • 🚗 Rollups optimize Ethereum's performance by gathering transactions "off the main Ethereum highway" (Layer 1) and then officially process them on a "side road" (Layer 2).


🌐 Overview

  • Ethereum Rollups are a Layer-2 scaling solution designed to enhance the throughput and features of the Ethereum network.

  • They operate by "rolling up," or bundling, multiple transactions off-chain and submitting them in batches to the Ethereum mainnet for data availability. By doing so, they significantly reduce congestion and gas fees while maintaining interoperability with Ethereum.

  • Rollups can also add new protocol features that would be impossible directly on Ethereum (e.g., PoP security to inherit Bitcoin Finality and Hemi's hVM Bitcoin Interoperability system).
