If one of the devs is here: Is there any possibility to add TaPoS to Peercoin? It could improve "fork resolution" greatly. (I'll propose that in the Peercoin forum if there is no reaction here.)
I dont know if you will get an answer, but it would probably be best to ask on the forum.
I see. I'm already preparing my post there.

Edit:
Started the thread here.and isn't following the "Not-Invented-Here syndrome".
I dont think you have to worry about this.
That's good to hear. The reason why I posted this is because in the past, in the Peercoin community, the Nothing at Stake problem has been described as a "myth". In my opinion it is not a myth - it is a real limitation of PoS. But in my opinion (I have read lots of blogposts, whitepapers etc. about that - e.g. Ethereum's PoS FAQ/Casper history) the problem can be made almost irrelevant. It is probably
already not a big danger (as far as enough people are staking and the "staker set" is relatively stable, what cold minting should achieve), but some improvements (with TaPoS among them) could make an attack even less likely.
