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.
Users can employ unused hard disk capacity to mine Bitcoins without the need for expensive mining rigs and other specialized hardware. Traditional mining hardware is energy intensive, noisy, produces a lot of heat, and is becoming increasingly specialized, moving beyond the means of ordinary people. With BHD, mining is simple and accessible. POW-based mining is all about raw computing power and energy output, whereas BHD's POC-based mining is far more energy efficient and returns to Satoshi Nakamoto’s original ideal that mining would be decentralized and performed by ordinary people. POC (Proof of Capacity) scans are only performed once every few minutes. For the rest of the time the hard disk is on stand-by with negligible power usage, greatly reducing energy costs. Based on capacity proof, it will support super-large blocks in the future and will add functions such as zero-knowledge proof. Solid-state drives are expensive, POC has no requirement for fast data processing, only capacity, so POC naturally eliminates ASIC chips. Currently, the amount of energy expended globally in POW mining is greater than the total energy output of 159 countries. The development of digital currencies shouldn’t have to be built on the wasting of resources. With BHD, POW calculations can be completed with a minimum of computing and energy resources.
