Arbitrum Nova vs xx network

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.

The xx network is a future-proof layer-one blockchain that facilitates thousands of transactions per second and protects against cryptography-breaking quantum computing. The xx network’s blockchain enables digital sovereignty by putting the users in control of the messaging and payments infrastructure. The xx blockchain utilizes breakthroughs in stake-based consensus protocols to provide energy-efficient and quantum-secure transactions at a scale to meet the needs for global payments.
