Here is my list for great innovations in crypto currencies...
1) Bitcoin ---------------- This is the genesis... all stems from here.
2) Namecoin ------------ This is the first coin to show the blockchain can be used for other things distributed.
3) Litecoin -------------- This coin was an attempt to put fairness back into distribution via being an ASIC killer. Scrypt.
4) Peercoin ------------- This coin introduces Proof of Stake as a method for creating new coins. Reduces energy consumption. ( Sunny King coin )
5) Primecoin ------------ This coin is a proof of concept for showing that POW can be 'useful' in some way. ( Finding prime number chains ) It also introduces a variable block reward based on difficulty. Thats two innovations in one coin! ( Sunny King is a genius IMHO )
6) Protoshares ---------- This coin is an interesting idea.. uses yet another POW ( asic/gpu killer attempt ) but it also introduces the idea that a coin can sort of be a 'share' of future projects.... a kind of IPO coin... so it is on my list.
7) LuckyCoin ------------ Random Block rewards... makes it kind of 'fun' for miners.... leads up to:
DogeCoin ------------- Hype/meme coin. Nothing new here except proof the public likes marketing... variable blocks.. many coins adds liquidity. People are willing to part with Doge to gamble, play games, etc...
Now the last interesting coins...
10) Ripple ----- The first 100 percent premined coin.. Means to be a payment network rather than a 'coin' per se. They have issues with distribution IMHO.
11) NXT------- Similar to Ripple, however they had people buy in with Bitcoin. The distribution was based on 'early investors' and as such it is kind of interesting to me... requires new technology.
So..... what is PMC? Where does it fit in?
PMC is like Bitcoin technology-wise. Bitcoin is still running strong and PMC is the same thing...
PMC is NOT like Ripple in that there is no centralization/foundation controlling 70 percent of the coins.
PMC is NOT like NXT in that it was not created with angel investors.
PMC is more like Doge. We didn't innovate any technology. ( Doge didn't either ) We just challenged a basic pre-conceived notion: "Pre-Mine == Bad".
PMC pre-mined all the coins but, GAVE EVERY LAST ONE OF THEM AWAY. So PMC is the first POD coin... "Proof of Distribution". Well we don't have 'proof' unless you want to peruse the block chain... But that is what happened...
PMC is 'energy efficient'
PMC is 'scarce'
PMC is 'deflationary'
PMC can be plugged into any system that uses BTC. So it is very 'portable' from a programmers perspective.
Just keep at it... eventually it will 'win'.
