Love chain is an innovative blockchain network based on DAG technology. The love chain is asynchronous, and the total sequence table cannot be determined without additional structure. The structure will take the form of a lighthouse. Chain tower is a set of criteria for the different units of some certification marks to determine the main link. All units that join the love chain are linked to the start unit, but since many units may have multiple parent chains, there are multiple paths between these units and the start unit. The path that intersects the most with the cells in the chain tower is considered the optimal path. Speed advantage, safety advantage, applicability advantage. Lovecoin is applicable to all applications that can be used on the network, such as payment, social networking, medical care, games, privacy, insurance, notarization, assets, charity, Internet of things, cloud storage, artificial intelligence, asset transaction, asset lending, encryption technology, VR AR and so on.
