Lisk is being developed to run blockchain applications and provide blockchain services. Ark is a simplified version with the blockchain app functionality removed and a data field added for bridged blockchains, enabling them to store and retrieve data from the main Ark chain.
It also has a different voting system, where 1 Ark = 1 vote for 1 delegate, or is split equally among the delegates selected, so the same 1 Ark might be 1/10 of a vote for 10 delegates, or 1/50th of a vote for 50 delegates.
Ark also adds Practical Byzantine Fault Tolerance (PBFT) to pre-approve blocks for inclusion in the blockchain to prevent forks, and adds forging from uncles to decrease latency and reduce block times by allowing new blocks to be forged even when a delegate does not have the previous block included yet.
Not really.
What you write is the vision, but not real at the moment.
Today I had taken a look at your GitHub - there is nothing.

I like your commitment.
But currently the Ark Bitcointalk-Thread looks like an insider job, hyped by unhappy Lisk members and spammed by cannabanana (as here at the beginning of Lisk).
we already explained why we have not released it and that it will be within this upcoming week or so. If you wanna talk about Github, then do you remember, Lisk didn't even release their GitHub link until MAINNET Launch!
