Sidechain: Expanding the Capabilities of the Main Blockchain
A sidechain is a separate blockchain that connects to the main blockchain (mainchain), allowing for two-way asset transfers. Its main goal is scalability, reducing the burden on the mainchain by processing transactions on a smaller network.
Sidechains also offer high customization, allowing developers to create unique rules and features for specific applications. Although separate, sidechains are not completely independent.
Their security is often derived from the mainchain through a two-way "peg" mechanism, where assets are locked on the mainchain when moved to the sidechain (often involving collateralization). This ensures that the value of the assets remains intact. In short, sidechains are an innovative solution to enhance the performance and flexibility of the blockchain ecosystem.
