‘Lambda Provides the Concept of a Verification Node in the Field of Decentralized Storage’: Co-founder Lambda

Lambda is a leading decentralized infrastructure project providing secure, reliable, and infinitely scalable decentralized storage network that enables data storage, data integrity check, security verification and marketplace for storage related services on the Lambda Chain Consensus Network.

In recent years, there have been frequent data leakage problems in major internet platforms. Even business giants such as Facebook and Marriott have not been spared. Returning the value of data to data owners is an inevitable trend in line with humans pursuit of freedom. Blockchain technology with P2P features, provide an opportunity for this and this area will be highly valued by the industry in the next few years. Lambda is the only blockchain storage infrastructure provider in China. It is sometimes referred to as the “FileCoin of China” or “Filecoin 2.0.” Despite Lambda’s short history of less than one year, it is on track with its development plan. The first release of source code was published in mid-November and its test network will launch in Q1 of 2019.

Lambda’s co-founder, Lucy Wang, talked to BlockPublisher and compared Lambda’s progress with its competitors, she stated;

‘Although there is a myriad of players in the data storage industry but only a handful of them have been implemented. The nature of a P2P network solves the grave problem of centralization. While trusted centralized nodes on a P2P blockchain ecosystem does not currently exist, we believe it can be solved with data integrity check and storage proof verification. There are only four projects that currently aim for this critical function: Sia, Storj, IPFS/FileCoin and Lambda. Among them, Sia and Storj are already obsolete, leaving IPFS and Lambda as the only competitive players in the market’.

‘Filecoin’s consensus mechanism is Proof of Storage (POS), where the S is not a currency interest but rather how long and how much data the miner has helped customers. Storage is one of the most important factors influencing the consensus, so Filecoin adds a series of additional anti-cheating rules to the storage certificate; this exponentially increases the difficulty of technical implementation. More so, it doesn’t help much in the POS itself as much as it adds to the fairness of the consensus’.

‘In a recent research study conducted between Filecoin and Lambda, data points show significant plateau in Filecoin project development while Lambda’s grows notably in 2018. The chart examines Lambda and Filecoin’s launch, successful code tests, project development and expected growth into 2019. While both companies are expected to launch its main network in Q2 of 2019, Lambda continuously shows consistent growth and progress while Filecoin is delayed and currently shows no progress’.

‘For the first time, Lambda provides the concept of a verification node in the field of decentralized storage. This is similar to the concept of third party administrator (TPA) mentioned in academic research. Instead of using one TPA node, Lambda created 1024 Validator position on the consensus network and used Verifiable Random Function (VRF) consensus mechanism to reach a verification result to the storage proof, which avoid the high risk of mutual cheating from both Storage and Verification nodes. Moreover, Lambda separates storage from its chain, which is more conducive to the upgrade and development of storage technology. The evolution of storage does not affect the transactions on the chain and is more conducive to the development and capacity expansion of the Lambda ecosystem’.

‘Lambda fully implements PDP, POR and EC technology, which greatly improves the security of decentralized storage. It also optimizes the storage space and traffic consumed by the algorithm to achieve the same level of secure storage. Lambdaenables more secure storage at a lower cost’.

Ms. Wang further talked about what real-world solution does Lambda propose according to the needs and said;

‘Lambda’s idea is to iteratively implement a blockchain-based PDP and POR system through the prototype system and realize all the advantages of PoST, such as continuous challenges and random challenges on the chain. Lambda believes that in the case of non-blockchain, in another verification algorithm different from POR, a PDP algorithm can be constructed; assuming a trusted third party, through a certain probability, to verify the data holding, and verification results are stored in an explicit and non-tamperable manner. The credible third-party audit, also known as TPA, must be able to pass the verification results through the chain to achieve non-tamperable results and a single-point trusted verification process must also pass a set of semi-trusted Validator nodes. Wherein consensus is completed’.

The main differentiator from FileCoin is Lambda’s use of validator nodes and roles, which streamlines the project development. Today, Lambda’s open PoST implementation using the Validator node provides new ideas and research directions for distributed storage and blockchain storage. Lambda’s Proof of Space Time algorithm is available on GitHub.
