Arbitrum Nova vs Scroll

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.

Scroll, a Layer 2 Ethereum network, aims to simplify scaling solutions for projects utilizing the Ethereum Virtual Machine (EVM). Its primary mechanism, zkEVM, integrates zero-knowledge proofs with the EVM, enabling rapid Ethereum transaction confirmation without the need to store and transfer additional transaction data. Scroll aims to establish a universal network that grants developers a user experience and security level akin to Ethereum while surpassing Ethereum in throughput, verification speed, and gas fee affordability
