MB (MBinternational Chain) aims to construct a blockchain system that integrates payments and commerce using zero-knowledge proof mechanisms. Initially issued via ERC20, MB uses POW as its consensus mechanism to establish foundational features such as wallets and a marketplace, thereby building a robust internal and external commercial circulation for MB. Once the mainnet is established, the zero-knowledge proofs it employs will provide fully decentralized payment confidentiality. As a public chain, it also offers a multi-component, extensible decentralized platform for a broad community of developers.
