Lisk is a public block chain platform that provides decentralized block chain apps
main difference between Lisk and Ethereum in my opinion is that Eth project has many bankers and whales behind it, supporting its advertising campaign with millions of dollars and also use that money to manipulate the price of it while those behind Lisk don't have any of it!
and the reason why Eth has "forked projects" is that everyone is looking for profit, and when you stick to a famous coin which is being advertised to death, you can also pump your own project and make money.
