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.
Waltonchain is a genuine, trustworthy and traceable business ecosystem with complete data sharing and absolute information transparency. It is created by the combination of technologies of RFID and blockchain, which push forwards the integration of block chain and the Internet of Things. Waltonchain combines blockchain with IoT (specifically RFID) to create a management system for supply chains. The project is named after Charlie Walton, the inventor of RFID technology and a pioneer in the space. Logistics systems are complex and commonly involve several different parties. As these systems grow, it becomes increasingly tough for businesses in the same vertical to coordinate with each other. On top of that, individual entities may have different processes that further hinder the ability to transfer data back and forth. Waltonchain uses RFID identification to track products during each step of production and distribution. The data associated with each item is stored on an immutable blockchain that ensures its accuracy no matter where in the process it is.The Waltonchain team is loaded with supply chain experience. Do Sanghyuk, one of the co-founders, was previously the Director of the Korean Standard Products Association. The other co-founder, Xu Fangcheng was the Supply Chain Management Director of Septwolves Group Ltd. The team is getting support from their Chief Scientist Advisor, Kim Sukku – a former vice president of Samsung. Waltonchain has no shortage of partnerships – several of which are with Chinese provincial governments. The team is working with the Fujian government to create a “smart maritime” blockchain incubator, and with the Jinhu government to build smart air purification and monitoring systems. The Waltonchain architecture makes use of a novel consensus mechanism known as Proof-of-Stake & Trust (PoST). Waltonchain innovates on the traditional proof-of-stake (PoS) model and integrates a node reputation based system into the consensus mechanism. PoST provides for adjustable difficulty for each node, to ensure that integrity in the ecosystem is rewarded. Waltonchain also gives sub-chain developers the option to choose their own consensus mechanism, for example, sub-chains can strictly just have PoS as a consensus mechanism, and not PoST. Waltonchain, by use of its RFID technology, has introduced a novel way with which blockchain can solve not only the inefficiencies found with supply chain management, but also IoT.
