This committee (detailed below) is responsible for expediting the process of storing, batching, and posting L2 transaction data to Ethereum's L1. They 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). While Arbitrum One implements the purely trustless Rollup protocol, Arbitrum Nova implements the mostly trustless AnyTrust protocol. Arbitrum Nova Īrbitrum Nova is a high-performance alternative to Arbitrum One's chain. This is made possible by the Nitro technology stack, a "Geth-at-the-core" architecture that gives Arbitrum One (and Nova) advanced calldata compression, separate contexts for common execution and fault proving, Ethereum L1 gas compatibility, and more. It lets you build high-performance Ethereum dApps with low transaction costs and Ethereum-grade security guarantees, introducing no additional trust assumptions. What Arbitrum production chains are available? Arbitrum One Īrbitrum One is a Layer 2 (L2) optimistic rollup chain that implements the Arbitrum Rollup protocol and settles to Ethereum's Layer 1 (L1) chain.
We’ll describe the available Arbitrum production and testnet chains, their differences, and the technology stacks that these chains use. In this conceptual overview, we’ll learn about the different Arbitrum chains and how they relate to each other.
Arbitrum chains are Layer 2 solutions built on top of the Ethereum blockchain, designed to increase scalability and reduce transaction costs.
