Please guys, try to understand what robbieboy2 is trying to say. He is not saying "NEM is a clone". He is saying "a lot of people think NEM is an NXT clone." And probably he is right.
It doesn't matter that this is not true. It matters that there are some people who think this. And it is a good idea to write a summery of the differences/improvements in a PDF.
There is one thing I disagree with you though, robbieboy2:Sure POI is different i guess, but at the end of the day its just a validation method.
POI is not just a validation method, it is a method to prevent the rich from getting richer, which is a problem at NXT.
Actually, PoI addresses a fundamental flaw in the block chain technology. It is some kind of a breakthrough. While we are at this I may want to add the beauty of the NEM design:
The design of the NEM platform is a tiered architecture. A tiered architecture has some advantages. The biggest advantage is that it makes cold wallet so simple. Secondly, it also makes the wallet so secure from hacks. One topology is to put the NIS in a Demilitarized zone in a firewalled setup and then if anyone is to be so paranoid, have another firewall with the wallet sitting behind it. Then one can run all sorts of applications behind it and use the NCC as a window to the NEM platform. This is all so neat - a protected NCC that acts as a gateway to some huge application that can operate in complete stealth mode. You cannot do that in any of the altcoin I know of (I must qualify though I care less about a lot of cryptos).
Multisig and a pruned block chain are also a couple more features that don't come with any "proprietary" wallet.
Honestly, this architecture has made me so excited from day 1 when I got involved. Just by looking at the two diagrams that were presented as a concept, I knew this was going to be the utopia of crypto 2.0. We should be proud of this as a gem of a NEM! Having said that, we still need the rest to be completed and I eagerly await till V1 where we should witness a giant slayer.
