MVC is a UTXO model of a first-level smart contract public blockchain with unlimited potential. This is a revolutionary blockchain solution designed to solve Bitcoin's congestion problem. MVC achieves unparalleled transaction speed, exponential scalability, high concurrency, and extremely low fees while maintaining decentralization. Combined with a cross-chain decentralized identity (DID) solution, MVC will be an ideal sidechain for Bitcoin, unleashing the full potential of Bitcoin in daily transactions, and providing a Bitcoin virtual machine, making the development of large-scale Web3 applications a possible.
