From what I can tell, the currencies Primecoin (XPM) and Peercoin (PPC) are very similar; both use the same proof-of-stake system, and hence have the same inflation rate. The main difference seems to be Primecoin's use of Cunningham chains for its proof-of-work. I want to ask some questions about this.

If there are no other differences, then what is the point of Peercoin today? Will Peercoin still be relevant in the future?
Exactly how useful are the scientific contributions made by Primecoin?

PPC and XPM are very different.

That is an interesting omission, considering they were created by the same person. Why does not it?

Because it's a different concept.

Sunny King presented Primecoin like a proof-of-concept for the new hash algorithm. So the innovation of this coin lies in the PoW system. Proof-of-Stake would probably have added too much complexity for this purpose.

Most everything you mentioned isn't right. XPM does not use PoS, they do not have the same inflation rate, and they were never designed to be similar  Grin

It appears that I was misinformed. Thank you all for explaining the matter!
