Many agree that blockchain technology has the potential to cause paradigmatic changes in many aspects of the global business process. Decentralized technology is already penetrating the cloud storage landscape, taking advantage of the security and reliability of blockchain, ensuring the fidelity of archived data and user privacy.
Recently, Ethereum World News (EWN) achieved with Lucy Wang, co-founder and CMO of Lambda, one of the main projects in the decentralized storage ecosystem to discuss issues related to storage blockchain and demonstration of the key event. Here are some extracts from the interview.
The Lambda approach to Blockchain storage
EWN: What are the unique aspects of Lambda's approach to blockchain-based storage that distinguishes it from its competitors both inside and outside the decentralized technology industry?
Lucy Wang: Lambda is the first project to announce a working Provable Data Possession (PDP) protocol called Lambda Provable Data Possession (LPDP). Furthermore, the project completed five key innovations:
- Innovatively designed the role of Validator that provides the verification service for the storage test. The Validator replaces the storage miner as a full-time archival-proof test resultant, which significantly improves the performance of the archiving and recovery system.
- In response to the PDP (Provable Data Possession) algorithm, Lambda has created a blockchain consensus network in an innovative way and used the role of validators to replace the third party administrator (TPA) in the 39, PDP algorithm.
- Innovatively modified PDP algorithm from synchronous to asynchronous communication, which drastically reduces the communication traffic for Challenge in the system. The use of chain data as a random seed for storage miners to release the Challenge addresses the randomness of the TPA challenges.
- Innovative update of the PDP algorithm from periodic verification to a verification set generated by miners to present the result of the verification at once and fully implement the Proof-of-Space-Time (PoST) verification.
- In Lambda's consent network, a set of Validators is randomly selected through the Virtual Routing and Forwarding (VRF) mechanism, and the results of the archival test are verified by the BTP (Byzantine Fault Tolerance) consent, which solves the problem of the & # 39; reliability of the single TPA verification.
EWN: Ordinary people tend to find the learning curve for new technologies discouraging. How does your project plan to make its solutions easy to understand for everyday users?
Lucy Wang: The adoption by the Lambda user is completed in several stages. In step one, we only target existing users who are familiar with the domain in which Lambda is located. In the next phase, we expand to a new user base from the word of mouth of existing users. We simplify language and technical parameters using business language and other simple methods to explain how people can use Lambda.
Bring the network to scale
EWN: two of the biggest problems for blockchain-based projects are security and scalability. Considering the vastness of the project's ambition, how do you plan to make it scalable while at the same time guaranteeing solid security.
Lucy Wang:
Security, reliability and high performance are three key features of unlimited scalable decentralized storage.
First of all, the consent network of the Lambda chain is a reliable mechanism that guarantees the integrity and data security by completing the technical verification processes on the blockchain. To ensure access security, Lambda provides an access control plan based on multi-authorization attribute-based encryption (MA-ABE), along with the ability to encrypt data and the ability to remove attributes through encryption of agents.
Secondly, Lambda applies three measures to ensure reliability: 1) incentive and sanctioning strategies 2) POR technology and 3) restoration of network orders and data recovery.
Thirdly, the high performance of a decentralized storage project depends mainly on four aspects: 1) the processing capacity of the consent network transactions 2) the matching capability for storage orders, or the efficiency of contract signature 3) the ability to upload data after matching orders and 4) the ability to control delays during data access.
Proof of keys
EWN: In short, what is Proof-of-Keys?
Lucy Wang: "Proof of Keys "is an event that was started by a well-known enthusiastic crypto Trace Mayer. During this event, cryptocurrency owners are urged to remove their cryptographic assets from exchanges and other third parties in an attempt to demonstrate solvency. The idea is that if the stock exchanges actually hold the cryptographic assets of the customers (which they claim to retain for customers after filing), then all customers should essentially be able to remove their assets from such third parties in any moment. Focusing on the fact that cryptographic holders should know how to store and protect their private cryptographic keys and effectively transfer them in their possession at will.
EWN: Lambda recently launched the first open source ProST-of-Space Time (PoST) algorithm for developers on GitHub. How does the upcoming Proof-of-Keys enter the general storage ecosystem that the project is trying to create?
Lucy Wang: In a P2P structured environment without authorization, security and reliability are the key factors to ensure mass adoption by everyday users. For the storage of cryptocurrencies, the creation of the "Key Test" event consists in calling the attention of all users who store cryptographic resources and creating awareness on users' rights and transparency in the total number of resources. and time intervals of stored resources.
In terms of a decentralized storage solution, the concept is exactly the same. We want to encourage every user to protect their own data privacy requesting the solution provider and his verification test of the storage space to ensure that the data was archived for as long as the purchased service. This is what we call the key module of a decentralized storage solution is & # 39; Proof of Data Integrity & # 39; and this is something that all actors in this area are struggling to develop. The PoST algorithm is a concept initially introduced by FileCoin to solve this problem, however Lambda is the first in the world to develop and publish the codes on GitHub.
