Lambda is a high-speed, secure and scalable blockchain infrastructure project that provides unfoldable data storage capabilities for decentralized applications through the logical decoupling and separate implementation of Lambda Chain and Lambda DB. Chain data collaborative storage, cross-chain data management, data privacy protection, data retention proof, distributed intelligent computing and other services. In addition, as the basic service of the blockchain, Lambda Chain provides millions of requests per second (RPS) through Sharding technology, and can grow as the system scales up; through sub-chain technology, provides Unlimited expansion of technical service capabilities for the future.
