Base vs Arbitrum Nova

Base, an Ethereum-based blockchain developed by Coinbase, operates as a Layer 2 (L2) network, leveraging Optimism to provide a secure, cost-effective, and user-friendly environment for decentralized application (dApp) development. With a mission to onboard the next billion users to web3, Base ensures near-zero fees, quick transactions, and robust security supported by Ethereum's infrastructure. At its launch, Base had over 100 dApps and service providers, aiming to solve the blockchain trilemma by prioritizing interoperability and composability among participating rollups. This approach enhances scalability while preserving security and decentralization.

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.
