Background Chain refers to a secondary blockchain that supports a primary blockchain by handling specific tasks off the main network. This helps to improve efficiency, reduce congestion, and lower transaction costs.

In many cases, Background Chains can manage tasks such as executing smart contracts or processing transactions with faster confirmation times. By delegating these operations, the main blockchain can focus on its core functions, such as maintaining security and consensus.

Background Chains typically operate with a distinct protocol or set of rules, allowing them to be flexible and specialized. They often communicate with the main blockchain to ensure data integrity and synchronization.

Using Background Chains can lead to enhanced scalability, as they can process a higher volume of transactions without burdening the primary network. Overall, this approach enables more efficient resource allocation and better performance for users while maintaining the integrity of the whole system.
