Sorry could you elaborate on marking a little? In what way is it different from normal P2P coin transfer? As you stated yourself Bitmark is a rather direct Bitcoin fork with Scrypt POW. But from the description I can't see what makes marking different either.
I can
elaborate a great deal, but maybe what is needed is something more concise.
Marking is the passing of reputation, similar to clicking 'like', the difference being that the marks are actually transferred from user to user, and marks have all the properties of crypto currency.
A marking also has a reason why, which can be a string message, or a URI, an identifier for anything from a web address to a telephone number to a geo location.
It is also a 'share' like a retweet or share on facebook.
Technically it is a protocol and an implementation with an API which works at the level of the web, not P2P, it is a separate thing on top of crypto which makes markings instant, off chain, and scalable to the size of the web. The crypto level part, bitmark, acts as the glue between implementations, allowing people to transfer marks from one service to another, or to storage and back, all the things you can do with Bitcoin.
The system then is a massive reputation graph which works over every website and every integrated thing in real life, it provides instant viral crowd funding for any creation, idea, or charity, and also rewards every curator of useful or interesting things. As a user you give spendable reputation with every marking, and receive it also for everything you share or make.
Let us say for example you post a sketch or a song you have created somewhere on the web, then people can mark you for it, as they would currently like, but in our model each marking is a little bit of rep and a little bit of money and optionally a share also. So if your sketch or song was good it can spread virally through the web and receive many marks, perhaps you have just earned a day or a weeks wages, and been fairly rewarded. In the current web system you post something on facebook or twitter and get meaningless likes/favs/karma from an infinite supply whilst the services benefit from your efforts. So we flip this around and make your reputation have true value again.
Perhaps you have a good idea, you can mention it, if it is good then it will be marked (you will get reputation and money and shares with each click), so now you have some incentive to progress your idea a little bit and maybe write something bigger about it. The marking process happens again and now John has joined you to help make a prototype, the process happens again and now you have a small community and reputation and funding to progress even further, and the thing scales out from there.
A nice thing is that your idea gave you lots of marks, and you maybe enjoyed the sketch from the previous example so you marked them with a higher amount, and the creator of that sketch was drawing another whilst listening to that song, so they marked the creator of that song as they listened.
Fast forward a little further and maybe you are going to demo your idea to a large manufacturer, you knew which taxi to get in because your mobile app showed you the companies reputation (each marking is of course also a review), and whilst travelling you think you need some lunch. Your google glasses give you a little overlay of markings against geo points as you look out of the window, which tell you that your friends ate at Frankies Pizza House last week and gave them good marks. So you stop there for lunch. Now maybe that table you sit at has a little brass token with the table number, but also NFC, so you just move your mobile device over the table number and you see the bill is to be 12 marks, so you tap your phone and slide your finger a little to add a tip to your waitress and mark her, then tap again to confirm. As you walk out side you get a little notification, you were just given a little mark back from Frankies, for being a polite customer.
As we say, Bitmark the currency is a little bit boring, it is just crypto currency. Marking however, that is quite fun and maybe just a little bit different from tipping
