Sidechain technology enables interoperability between the sidechain and the main chain through specific interfaces, allowing assets and data on the main chain to be circulated and processed on the sidechain, thus providing higher scalability, security, and flexibility for the blockchain system. Sidechains can be used to implement business scenarios such as asset issuance, transaction optimization, and smart contract execution while maintaining the decentralization and security of the main chain. For example, Bitcoin and the Lightning Network are types of sidechains."}]}],"pr":"899ade9531dbb74c27384a1e347d99a4ced65e68eb1f679c16e36ca404cbe57a"}
