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.
Solarcoin is a Scrypt based alternative digital currency and its innovation comes from the secondary proof of work reward: the Solar Proof of Work. Green solar energy producers are entitled to receive one SLR for every MWh electricity generated. In order to claim a Solar Proof of Work reward, solar plant owners must submit 3rd party verified energy generation certificates such as a Solar Renewable Energy Certificate (SREC) or equivalent country specific documentation. All Solar Proof Of Work rewards will be stored as transactions in the blockchain. The supply of SLR comprises of the following: - The Mining Pool: 105 million Solarcoins (0.1%) to be publicly mined over the next 40 years. All publicly mined Solarcoins represent historically generated and unclaimed solar electricity. - The Generator Pool: 97.5 billion SolarCoins (99.4%) are currently stored in the OCA non-circulating generation pool account. These will be exchanged for Solar Proof of Work claims of solar electricity generation submitted over the next 40 years at the rate of 1 SLR per MWh of solar energy. - The Genesis Pool: 500 million Solarcoins (0.5%) are stored in the genesis pool account for environmental charities, early volunteers, advisers, builders and maintainers of SolarCoin infrastructure. Genesis pool circulation is capped so that it will never represent more than 5% of total Solarcoin in circulation.
