What We're Building

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 enables developers to build applications and deploy their own side-chain linked to the Lisk network, including a custom token. Thanks to the scalability and flexibility of side-chains, 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.
