The goal of MB (MBinternational Chain) MEBO is to use the zero-knowledge proof mechanism to build a blockchain system that integrates payment and commerce. MB is initially issued through ERC20 and uses POW as a consensus mechanism to realize basic functions such as wallets and shopping malls. To build a strong business internal and external circulation of MB, after the completion of the main network, the zero-knowledge proof it uses will provide complete decentralized payment confidentiality, and at the same time, as a public chain, it will provide developers with a multi-component scalable go Centralized platform.
