Sidechain technology is similar to mainchain technology but has independent consensus mechanisms, transaction validation, and governance models. The emergence of sidechains aims to address some limitations of mainchains, such as scalability, performance, and security issues. By transferring part of the business or assets to the sidechain, the pressure on the mainchain can be alleviated, thus improving the overall operational efficiency of the blockchain ecosystem. Meanwhile, sidechains also provide developers with a new platform for experimentation and innovation in exploring and improving blockchain technology. In summary, sidechains represent an exciting development in the field of blockchain technology, promising more flexible  and efficient solutions for businesses and users alike."}]}],"pr":"6e67e13b3588373f41c8ff150c443c432cab4d9d0958d7a76346ce4fc8136d19"}
