Lisk is a blockchain application platform, founded by Max Kordek and Oliver Beddows in early 2016. Based on its own blockchain network and token LSK, Lisk will enable developers to build blockchain applications and deploy their own sidechain linked to the Lisk network, including a custom token. Thanks to the scalability and flexibility of sidechains, developers can implement and customize their blockchain applications entirely. Lisk aims to make blockchain technology more accessible with a SDK written in JavaScript, special focus on user experience, developer support, in-depth documentations and the Lisk Academy. The Lisk network is operated using a highly efficient Delegated Proof of Stake (DPoS) consensus model, which is secured by democratically elected delegates. Lisk, headquartered in Zug, Switzerland, raised over 14,000 Bitcoins in funding during its ICO (Initial Coin Offering), making it valued at over $4 billion at its peak. Lisk is an open source blockchain platform which is powered by Lisk (LSK) Tokens that allows developers code decentralized applications (dApps) in JavaScript programming language. With Lisk, developers can build applications on their sidechain linked to the Lisk Network, and also with their custom token. In that sense, Lisk is similar with the Ethereum blockchain. However, the Lisk platform hasn’t been built to create smart contracts, but to develop diverse apps and functionalities using the LISK AppSDK framework. It is a modular cryptocurrency as this coin involves ‘modules’ that serve as the basis of its design and construction. The overall design is its trump card - the Lisk system allows anyone to use its ‘designing blocks’ to construct their own decentralised apps. It utilises 'sidechains'. Besides, many former members of Ethereum core members joined Lisk. On June 8 2016, Lisk CEO Max Kordek announced the addition of Charles Hoskinson (ex-CEO of Ethereum) and Steven Nerayoff (ex-advisor for Ethereum) as Senior Advisors of Lisk, to facilitate Product Development.
Lambda is a fast, safe, and scalable blockchain infrastructure project, which provides decentralized applications (DAPPs) data storage capabilities with unlimited scalability and fulfills services such as multi-chain data co-storage, cross-chain data management, data privacy protection, PDP, and distributed intelligent computing through logic decoupling and independent implementation of Lambda Chain and Lambda DB. Through the logical decoupling and separate implementation of Lambda Chain and Lambda DB, we provide infinitely scalable data storage capabilities to decentralized applications and achieve Multi-chain data cooperative storage, cross-chain data management, data privacy protection, data ownership proof, distributed intelligent computing and other services. Additionally, as the underlying service of blockchain, Lambda Chain provides millions of requests per second (RPS) through Sharding technology, which can grow as the scale of the system expands; and it also offers technology service capabilities for future unlimited expansion through sub-chain technology. We believe that all storage projects follow the core requirement of Provable Data Integrity.Also, it is crucial for data projects to store data in an infeasible storage node and make them trusted and secure, in the academic world, there are mainly two approaches which are Provable Data Possession (PDP) and Proofs of Retrievability (POR) depending on the usage scenarios. Lambda has applied these two approaches in blockchain through academic research and engineering verification, which has eliminated the core obstacles of decentralized storage.
