Flow vs Arbitrum Nova

Flow is a layer one blockchain designed from the ground up for consumer apps and the digital assets that power them. The network runs on a Proof of Stake consensus mechanism with a unique "multi-role" architecture that solves the blockchain trilemma, balancing scalability, efficiency, and cost.

FLOW ($FLOW) is the native utility token that is used for:

• Fees for processing transactions and storing data.
• Buying, selling, and trading assets on Flow
• Staking and delegating to secure the network

Flow tools include:

• Cadence, a purpose-built smart contract programming language designed for consumer-grade applications
• Full EVM equivalence, allowing anything from Ethereum to work on Flow
• Protocol-level account abstraction and mobile support for onboarding new users
• Cross-chain interoperability with the wider web3 ecosystem
• Developer hub with comprehensive documentation and tools

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.
