Musichain is a new digital blockchain technology jointly developed over three years by International Risk Control Copyright Group Holdings Co., Ltd. and the Spotify technology team. It is one of the core areas for the practical application of blockchain technology. It includes mainstream features such as music copyright acquisition, peer-to-peer transfers, property holder onboarding, online and offline transaction payments. By building on Ethereum (an open-source, public, distributed computing platform that provides a decentralized Turing-complete virtual machine supporting the execution of smart contracts), it will support mainstream cultural sector copyrights and in-car music social software applications in the future, with plans to gradually develop and extend applications to adjacent industries.
