Lambda is a fast, safe, and scalable blockchain infrastructure project, which provides decentralized applications (DAPPs) data storage capabilities with unlimited scalability and fulfills services such as multi-chain data co-storage, cross-chain data management, data privacy protection, provable data possession (PDP), and distributed intelligent computing through logic decoupling and independent implementation of Lambda Chain and Lambda DB. In addition, as a blockchain infrastructure service, with the use of Sharding technology, Lambda Chain provides the capability of processing millions of requests per second (RPS), which increases with the expansion of the system scale; with the use the sub-chain technology, it provides future-oriented technical service capabilities with unlimited scalability.
Lambda project is dedicated to providing a data storage infrastructure for blockchains and DAPPs and based on which it intends to offer storage and access capabilities of the decentralized cloud database. Moreover, based on scale-out and Sharding technology, it enables high-speed transactions; based on the trunk chain technology and cross-chain transaction verification, it enables cross-chain transactions, and data access and verification within the system; based on the Bridge Control Protocol (BCP), it enables the cross-chain communications with other chain systems. By providing a series of infrastructure capability services including block storage, file storage, object storage, KV storage, and table storage, which can be extended without limit, and fast network transmission - remote synchronization (rsync), Lambda makes it possible for DAPPs to perform data generation, computing, transmission, storage, and retrieving in an easy manner. Moreover, attribute encryption and agent encryption technologies applied in the project protect data privacy. Still, Lambda project is featured with flexible data structure, powerful programming interface, and efficient backup.
