Arbitrum Nova employs the AnyTrust protocol. Here are its key features: Data Availability Committee (DAC): A committee manages transaction data instead of storing all data on Ethereum, reducing costs, especially in high-transaction volume scenarios. Committee Selection: The DAC comprises selected nodes that ensure data availability, adding a level of trust assumption compared to Arbitrum One. Use Cases: Suited for social applications, gaming, and other high-transaction volume dApps due to its cost-effectiveness and scalability.
