</b> MetaMUI is a permissioned public blockchain network that many central banks, commercial banks, and other financial institutions can publish their CBDC(central bank digital currency)s. MetaMUI is also an identity-based meta-blockchain that uniquely solves the CBDC design trilemma of privacy, identity, and programmability. By decentralizing identity and multi-ledger mechanisms, MetaMUI uniquely positions itself as an enabler of privacy-preserving CBDC that is fully compliant with financial regulations. MetaMUI is the first peer-to-peer digital cash that can confirm the transaction without requiring either blockchain consensus or the mediation of a central server. With its true peer-to-peer nature of digital cash, MetaMUI can outperform centralized account-based and blockchain token-based digital payment. It can achieve more than 1 million transactions per second. MetaMUI is the first blockchain that solves the serialized operational structure of the blockchain consensus process. MetaMUI can process transactions in parallel and independently. With this decentralized operation capability, MetaMUI can achieve virtually unlimited scalability simply by adding more and more nodes to the network. It is one of the technological candidates to implement the World Reserve Currency that can serve the entire humanity. In short, MetaMUI is a mainnet coin that fuels the MetaMUI network and supports the MetaMUI blockchain development. It is a future value-backed coin. It is designed as a deflationary coin that accumulates and continuously increases the backup assets of MetaMUI from the project incomes of MetaMUI Network. Project income sources of MetaMUI Network are CBDC publication license and usages fees, NFT(Non-Fungible Token) and NFT contents publication fees, Tokenized Asset publication and trading fees, SSID(Self Sovereign Identity) related Verifiable Credential publication and verification fees, and more.<b>...
