...after all POW is actually secure.
We agree. PoW is actually secure.BUT... PoW is an incredibly inefficient and wasteful way of obtaining that security, and requires trillions upon trillions of wasted hashes per blocktime. The key point is
DPoS Lisk obtains blockchain security levels equal to that of PoW Bitcoin or Ethereium with ONLY ONE hash per 10 second blocktime, NOT trillions of hashes like BTC or ETH.
That's why Lisk is being valued so highly. LISK represents BOTH a revolutionary way to secure a blockchain AS WELL AS a revolutionary easy way to create sidechains and dapps.Lisk is superior to Ethereum on both counts. Period.I know you know all these points by heart, and you're good at delivering them. But DPOS is not the panacea you think it is. If it were, every currency would move to it.
1. Regarding resilience, how do you guard against a DDOS attack on the 101 delegates?
2. Regarding decentralization, how do you prevent a Sybil attack of delegates?
3. Regarding incentives, long term, how do keep your voters interested in nominating the delegates?Ans. 1. You can't 2. You can't 3. You won't1. Regarding resilience, I can guard against a DDoS attack by letting a big-ass firewall system pass data only from the other 100 IP addresses I know are from my fellow delegates. I don't have to respond to every packet thrown my way and so fall behind with my blocktime tasks. A DDoS doesn't have to overwhelm 101 delegates; it has to overwhelm 101 big-ass firewall systems protecting those delegates. That's a much tougher problem.
2. Regarding decentralization, I can examine each of the 101 delegates that are initially selected and make sure they are 101 individual people, then apply the same scrutiny to the trickle of replacements as they come along. Hey, I personally am doing that right now - take a look:

So...
Ans. 1. We can 2. We are 3. We will
