Lambda is a high-speed, secure, and scalable blockchain infrastructure project. Lambda serves as the data storage backbone for blockchains, with its own chain for billing, transactions, encryption, and access control. LAMB is the native token of the Lambda project, which can be used to create nodes that consume memory and storage resources.
1. Project Background
Lambdas primary business on the B-side is cold backup of enterprise critical data, achieved through distributed storage deployed within the Lambda network to back up database cold storage. Customers back up their data onto Lambda, where the network periodically conducts data integrity and recoverability proofs. Within the blockchain community, Lambdas partners include IOST, DATA, and distributed computing projects like Ankr and Perlin. Yifang Cloud is one of the initiators of Lambda and an important partner outside the crypto sphere. In terms of business development, the internal deployment version of Lambda has signed contracts with 67 users in industries such as insurance and banking.
The most crucial role in the Lambda ecosystem is that of miners, whose number has exceeded 10,000. The pledged storage space connected exceeds 300 petabytes. Recently, Lambda Network passed a proposal where miners LAMBS rewards balance will be mapped to TBB, upgrading from a single-token to a dual-token system. Miners receive 1 terabyte of mining rights for every terabyte of storage provided, and a staking mechanism for miners has been added to the network.
2. Roles and Responsibilities in the Lambda Network
In the Lambda network, there are four roles: Storage Miners (storage space suppliers), Verification Miners (ensuring data integrity and security and packaging transactions), Retrieval Miners (providing download bandwidth), and Users (storage demanders). The 1024 Verification Miners, promoted from Storage Miners, form the consensus network of LambdaChain.
3. LambdaChain Consensus Network
The LambdaChain consensus network is the foundation on which the Lambda network operates, consisting of 1024 Verification Miners (promoted from Storage Miners) who participate in consensus through the VRF algorithm and reach agreement using an improved BFT algorithm. The main significance of the consensus network is:
- The LambdaChain consensus network acts as a trusted mechanism to ensure data integrity and security, replacing the brand endorsement of centralized storage. It completes the technical process for verifying data safety and integrity on-chain.
- A Marketplace (storage transaction market) is built on the consensus network, where storage miners sell storage space and users buy it. The value of data storage is determined by market demand.
4. How the Lambda Network Operates Based on the LambdaChain Consensus Network
1. In the Lambda network, storage miners provide Proof of Spacetime (PoST) to the consensus network composed of verification miners, generating proof sets periodically. A fixed number of validators are randomly selected by the VRF algorithm to participate in consensus, and they reach agreement on submitted blocks using an improved BFT algorithm. This ensures the security of stored data.
2. During transactions on the Marketplace: storage miners pledge hard drive sectors to the consensus network, list their storage space for sale on the Marketplace, and storage users initiate purchase requests. Through the transaction market, storage needs are matched, and users store their data in the space provided by storage miners.
To ensure data storage safety and periodic fee settlements, block information includes transactions and settlement details, providing settlement services on-chain.
