PoW vs DPoS:
Contrary to popular belief, 101 single-purpose servers are far more decentralized than thousands of miners lumped on a few mining pools;
not to mention the fact that with PoW, you have an ongoing arms race to become the most powerful miner,
leading to an ever increasing energy consumption of the whole network bottlenecked through these pools.
The Lisk Network has no such difficulty adjustments, and is extremely eco-friendly.
Every pool is just 1 server in the network, not a bottleneck.
But what about the sidechains when Lisk projects are released? How to secure them?
Side Chains may choose whatever algo model they like, including mirroring the Lisk core.

does the lisk website use cloud flare, are addresses that we used to login potentially compromised?
no

Why does the lisk team keep going back around to changing DPoS?
The current system works as it was designed to work.
The Lisk Team should be working 100% on getting that SDK rebuilt as thats the only thing that will pull this turd of a coin out of it's death spiral.
It has yet to be "changed" since the first lisk implementation, and the SDK is exactly what is being worked on
