By attacker do you mean by doing damage or by exploiting it for profit ?
The +50% attack scenarios (and the protective measures) are applicable to both kind of attackers, while the DDoS attacks are mostly used to do damage rather than profit. Of course, by weakening the current miner or delegates, an attacker may also increase his own chances of building blocks and thereby his profits. My proposal solves this issue by hiding the identities of the next minters until they release their blocks (just like Bitcoin does).
Unless there can be a substantial improvement over pat coin in fairness and initial distribution etc then i think we have a problem and maybe no need for another coin.
Initial distribution is a very important aspect of any cryptocurrency. I didn't elaborate on that in my post and might cover it in an upcoming article. My current idea is to perform some intelligent sampling of past and present Bitcoin owners/miners, and assign one account to each entity identified as such. I'm not sure if I should require Proof-of-Burn on top of that.
So i would rather see someone more knowledgeable in that area post judgments on this topic.
I support looking into new things though.
Thanks for your encouragement. It's hard to get noticed, even though my idea is quite novel I think. I'm still looking for qualified feedback and crititicism from users like smooth, iamnotback, monsterer, jl777 etc.
