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, PDP, and distributed intelligent computing through logic decoupling and independent implementation of Lambda Chain and Lambda DB. Through the logical decoupling and separate implementation of Lambda Chain and Lambda DB, we provide infinitely scalable data storage capabilities to decentralized applications and achieve Multi-chain data cooperative storage, cross-chain data management, data privacy protection, data ownership proof, distributed intelligent computing and other services. Additionally, as the underlying service of blockchain, Lambda Chain provides millions of requests per second (RPS) through Sharding technology, which can grow as the scale of the system expands; and it also offers technology service capabilities for future unlimited expansion through sub-chain technology. We believe that all storage projects follow the core requirement of Provable Data Integrity.Also, it is crucial for data projects to store data in an infeasible storage node and make them trusted and secure, in the academic world, there are mainly two approaches which are Provable Data Possession (PDP) and Proofs of Retrievability (POR) depending on the usage scenarios. Lambda has applied these two approaches in blockchain through academic research and engineering verification, which has eliminated the core obstacles of decentralized storage.
Proton is a public chain that is dedicated to data fusion and collaboration. It builds the fundamental infrastructure for data security and high-efficiency data collaboration processing across various data sources, unleashing the real potential of big data and artificial intelligent applications on different industries. With freeing the data from silos, from a single online shop to the IoT industry giants can break through their bottle neck of lacking valid data samples and insufficient recognition of data via 'Proton Inside'. Proton Chain Proton is a Blockchain Based System enabling the Unified ID system for Data Storage and Collaboration.It allows decentralised data sharing and processing with guaranteed privacy among different platforms,freeing data from today’s silos. Proton network can well be adopted to empower the digital marketing eco-system using blockchain and provides support and service to advertisers, agents, DSPs, SSPs, DMPs and end users.
