Fantom vs Arbitrum Nova

Fantom is a high-performance, scalable, and secure smart contract platform engineered to surpass the constraints of preceding blockchain platforms. Operating as a permissionless, decentralized, and open-source network, Fantom leverages Lachesis, its asynchronous Byzantine Fault Tolerance (aBFT) consensus mechanism. This innovative approach enables Fantom to achieve remarkable speed and affordability compared to older technologies while maintaining exceptional security standards.

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.
