Sidechains are a method for creating separate, customizable blockchain networks that are connected to a main blockchain.
This allows for the creation of specialized, purpose-built blockchain networks that can be used for specific use cases or applications.
Sidechains are typically implemented through the use of two-way pegs, which allow for the transfer of assets or data between the main blockchain and the sidechain. This means that users can move assets between the main blockchain and the sidechain as needed, without having to rely on intermediaries or centralized exchanges.
Some of the key benefits of sidechains include increased scalability, enhanced privacy and security, and greater flexibility for developers and users. By creating separate, independent blockchain networks, sidechains can help to alleviate some of the congestion and scalability issues that can arise on the main blockchain.
