Hi D-Lux,
Lisk is a blockchain network just like Ethereum that gives developers the tools needed to create D-APPS
in several programming languages. Both Lisk and Ethereum are more or less "just" developing the basic
framework to give developers a possibility to write, test and deploy applications on the blockchain.
Shift is a fork of Ethereum (the first of its kind, launched in August 2015). We offer all the functionality
from Ethereum and full D-APP compatibility to it. Our flagshipp application is decentralized Internet, in
its mature state complete with servers, search engines, forums, email and more (compare to Maidsafe's
Safe Network).
There is much more to Shift than that, so I suggest you join our Slack if you're interested to know
more about us and our community.
