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.
MARK.SPACE is an open-source platform for the creation of 3D/VR/AR-compatible spaces and objects of any purpose, as well as their quick launch and integration into a unique ecosystem. The platform supports a crypto economy and is powered by Blockchain. MARK.SPACE supports all Internet browsers (preferably Chrome) and, at the same time, is compatible with CardBoard, Oculus and HTC Vive. A desktop PC or tablet is all that is needed to create a state-of-the-art VR store, office, community or other space for business or entertainment. The MARK.SPACE universe consists of multiple VR spaces (units), in which each unit can be linked directly to its own top-level domain. The property right to the units is guaranteed by recording all transactions involving units (creation, sale, purchase or rental) on the Blockchain. All unit owners may buy, sell or rent their units to others using smart contracts. MARK.SPACE has an internal currency - the MARK token (MRK), which is a utility token (not a paper bond), allowing all users to sell and buy VR spaces and objects, consume various goods and use services, pay salaries to their employees and to buy ads to promote their businesses through the MARK.SPACE platform. GPU-miners who will be rendering VR spaces and objects for the platform’s users will also receive rewards in MRK tokens (Proof of Work (PoW) Concept).
