LNG public chain is a brand new asset interaction protocol, where different forms and heterogeneous assets (native digital currencies, digital assets) running on the LNG blockchain can be registered, exchanged, and more complex interaction operations based on contracts can be carried out through the LNG protocol.The LNG public chain adopts a three-layer architecture: application layer, contract layer, and data layer. The application layer is friendly to multiple terminals such as mobile terminals, making it convenient for developers to develop asset management applications; The contract layer adopts Genesis contracts and control contracts for asset issuance and management, and supports the extended UTXO model BUTXO at the bottom layer, optimizing the virtual machine and adopting a self reflection mechanism to prevent the dead end state in Turing completeness; The data layer uses distributed ledger technology to realize asset issuance, spending, exchange and other operations. The consensus mechanism uses the artificial intelligence ASIC chip friendly POW algorithm, and introduces matrix and convolution calculation in the hashing process, so that mining machines can be used for AI Hardware acceleration services after being idle or eliminated, thus generating additional social benefits....
