It is an open source blockchain application written in javascript. It enables developers to create distributed and manage decentralized blockchain application by deploying their own side chain linked to the lisk network. It attempts to be the first as a modular cryptocurrency.
The blockchain is actually is on a separate side chain, separated from the main blockchain. This helps in scalability issues that many blockchains have issues with. It uses the Delegate Proof of stake(DPoS) algorithm created by BitShares. In DPoS only the first 101 delegates can forge the network. It functions through a series of rounds and around consist of 101 individual blocks.
LSK uses proof of storage algorithm to forge cryptocurrencies. Delegates have got the rights to create their own pools and engage in mining and the rewards will be distributed to all the participants in the pool.
Coins can be stored on different wallets which are available on the internet.
Its team is more concerned with developing the technology than making content for press releases. Developers have flexibility when it comes to creating their own blockchain for their applications. The Javascript SDK has the potential to attract many dApp developers due to its ease-of-use.
They have gone a different way to most other developing dApp platforms. Instead of focusing on marketing to investors before having a working product, it is instead working silently on technology made easy for developers whose applications will bring utility and true value.
