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

1. Project background

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

The most important role in the Lambda ecosystem is the miners, whose number has exceeded 10,000. The accessed pledge space exceeds 300PB. Recently, the Lambda network passed a proposal that the miners' LAMBS reward balance will be mapped to TBB, upgrading from a single token to a dual token. Miners get 1TB of mining rights for every 1TB of storage they provide, and a mechanism for miners’ pledges has also been added to the network.

2. Roles and responsibilities in the Lambda network

There are four roles in the Lambda network: storage miners (storage space suppliers), verification miners (ensure data integrity and security and package transactions), retrieval miners (provide download bandwidth), users (storage demanders), and storage The 1024 verification miners promoted by the miners constitute the LambdaChain consensus network.

3. Lambda Chain consensus network

The Lambda Chain consensus network is the basis for the operation of the Lambda network. It is composed of 1024 verification miners (promoted from storage miners). The consensus nodes are elected through the VRF algorithm, and consensus is reached through the improved BFT algorithm. The main consensus network The meaning is:
1. The Lambda Chain consensus network as a trusted mechanism ensures data integrity and security to replace the brand endorsement of centralized storage, and completes the relevant technical process of complete verification of data security on the chain.
2. A Marketplace (storage trading market) is built on the consensus network, which is used to store miners selling storage space and users buying storage space. The value of data storage is determined by market demand.

Fourth, how the Lambda network operates based on the Lambda Chain consensus network

1. In the Lambda network, storage miners provide PoST space-time proofs to the consensus network composed of validating miners, and periodically generate proof sets; a fixed number of Validators are randomly selected by the VRF algorithm to form consensus participating nodes, and through the improved BFT algorithm Reach a consensus on the submitted block and broadcast it to the network to ensure the security of data storage.
2. During the Marketplace transaction process: storage miners mortgage hard disk sectors to the consensus network, place orders on the Marketplace and sell their own storage space; Data is stored in the storage miner's space.
To ensure data storage security and periodic fee settlement. Block information includes transfer transactions, transaction settlement, etc., and transaction settlement is provided on the chain.
