The project of Lesschain aims to provide an extensible and flexible blockchain that supports digital asset transactions, data access, and process control through a hierarchical structure. It creates a framework to allow users to execute smart contracts in an efficient manner. Besides, it provides an architecture for development that uses the underlying infrastructure to generate sub-blockchains quickly and easily. It is a blockchain platform that provides the necessary components for the erection of sub-blockchains, and provides solutions for the testing of new ideas, the deployment of private chains, the processing of complex  tasks, and the application of smart contracts.
