Lambda is a blockchain infrastructure project that offers fast, secure, and scalable capabilities for decentralized applications (DAPPs). It enables data storage with unlimited scalability and provides services such as multi-chain data co-storage, cross-chain data management, data privacy protection, proveable data possession (PDP), and distributed intelligent computing. Lambda achieves this through logic decoupling and independent implementation of Lambda Chain and Lambda DB. Additionally, Lambda Chain utilizes Sharding technology to process millions of requests per second (RPS), which increases as the system scale expands. It also employs sub-chain technology to provide future-oriented technical service capabilities with unlimited scalability.
