Lambda is a high-speed, secure and scalable blockchain infrastructure project. Lambda is the blockchain’s data storage infrastructure with its own chain for billing, transactions, encryption and access control. LAMB is a native token for the Lambda project that can be used to create memory and storage resources that consume nodes.

1. Project background

Lambda's main business on the B-side is cold backup of enterprise key data, and the cold backup of database is backed up through distributed storage deployed by Lambda intranet. Customers back up data to Lambda, and the network regularly conducts proof of data integrity and proof of data recovery. Lambda's partners in the circle include IOST, DATA, distributed computing projects Ankr and Perlin. Yifang Cloud is one of the initiators of Lambda and an important partner outside the Lambda currency circle. In terms of business promotion, the Lambda intranet deployment version has signed contracts with 67 users including the insurance industry and the banking industry.

The most important role in Lambda ecosystem is miners, with the number of people currently exceeding 10,000. The access pledge space exceeds 300PB. Recently, Lambda Network passed a proposal that miners' LAMBS reward balance will be mapped to TBB, and upgraded from a single to a dual token. For every 1TB of storage provided by miners, a mechanism for miners to stake is also added to the network.

2. Roles and responsibilities in the Lambda network

There are four roles in the Lambda network: storage miner (storage space provider), verification miner (to ensure complete and secure data and package transactions), search miner (to provide download bandwidth), and users (to store demander). The 1024 verification miner promoted by storage miners constitutes the LambdaChain consensus network.

3. Lambda Chain consensus network

Lambda Chain consensus network is the basis for the operation of Lambda network. It consists of 1024 verification miners (storage miners promoted). It elects consensus nodes through VRF algorithms and reaches consensus through the improved BFT algorithm. The main significance of the consensus network is:
1. The Lambda Chain consensus network serves as a trusted mechanism to ensure the integrity and security of data to replace the brand endorsement of centralized storage, and completes relevant technical processes for complete data security verification on the chain.
2. Marketplace (storage trading market) is built on the consensus network to store miners' sales storage space and users' purchase storage space. The value of data storage is determined by market demand.

IV. How does the Lambda network operate based on the Lambda Chain consensus network

1. In the Lambda network, storage miners provide PoST spatio-temporal proof to the consensus network composed of verification miners, and regularly generate a set of proofs; the VRF algorithm randomly selects a fixed number of Validators to form a consensus participating node, and reaches a consensus on the submitted blocks through the improved BFT algorithm and broadcasts it to the network to ensure the security of data storage.
2. During the Marketplace transaction process: the storage miner mortgages the hard disk sector to the consensus network, place orders on the Marketplace and sells his own storage space; the storage user initiates purchase requirements and completes the matching of storage needs through the trading market, and the user stores the data in the storage miner's space.
To ensure the security of data storage and periodic fee settlement. Block information includes transfer transactions, transaction settlement, etc., and transaction settlement is provided on the chain.
