Arbitrum Nova vs Ethereum

Arbitrum Nova is a high-performance alternative to Arbitrum One's chain. While Arbitrum One implements the purely trustless Rollup protocol, Arbitrum Nova implements the mostly trustless AnyTrust protocol. The key difference between Rollup and AnyTrust is that the AnyTrust protocol introduces an additional trust assumption in the form of a Data Availability Committee (DAC). This committee (detailed below) is responsible for expediting the process of storing, batching, and posting child chain transaction data to Ethereum's parent chain. This lets you use Arbitrum in scenarios that demand performance and affordability, while Arbitrum One is optimal for scenarios that demand Ethereum's pure trustlessness.

Ethereum emerges as a decentralized, open-source blockchain platform empowering developers to craft and deploy smart contracts alongside dApps. Pioneering the smart contract concept, Ethereum enables self-executing agreements with terms directly encoded into its blockchain, eliminating the need for intermediaries. Additionally, Ethereum serves as a hub for the creation and exchange of NFTs (Non-Fungible Tokens) and various digital assets. Its intrinsic cryptocurrency, Ether (ETH), facilitates network transactions and incentivizes miners to uphold network security. Ethereum's evolution to Ethereum 2.0 introduces a proof-of-stake (PoS) mechanism, aiming to enhance scalability and energy efficiency.
