Yes its a project currently in development by Duffield and whomever else is hired by the DGBB. I’m going through the white paper now, but it looks to be very interesting indeed. They have some top notch stuff in there. The easiest way to envision the Dash network is to look at it in layers Dash 1.0 as similar to Bitcoin. This is where cryptographic signing of mined blocks takes place, etc. very low level protocol. This is also where Dash and Bitcoin part ways. On top of this is layer 2 or the masternode network. This is where masternodes work together to do instantX, Coinjoin etc. They are incentivized to do this because Masternodes receive 45% of mining rewards (other 45% to miners, remaining 10% goes to the network for development, marketing, etc. and is voted upon by Masternodes).
Evolution is layer three which is built upon the masternode network. Having masternodes is actually a very useful thing because they can be used to for more than just anonymizing and mixing the transactions on the network. This is where evolution comes in, there is, according to the white paper, DAPIs, lightclients, social clients, named aliases (so ‘regular’ people don’t have to deal with unreadable addresses) planned to be built on top of the network. This allows for DAPIs to connect to the network and handle transactions ‘off chain’ so to speak. The problem with Bitcoin transactions is in order to do them you either have to: have a full blockchain at your disposal in order to ‘trust’ that the transactions are valid, OR you have to be running a light client who does that for you and trust THEM. The whole point is not trusting centralized authorities.
This is where masternodes come in. This gives you the benefits of the centralized service, without the need to have a full blockchain yourself. What will happen is that Masternode quorums will be randomly selected to verify the transaction. If all 7 (I believe) agree, then the work is verified and added to the blockchain. But since this is masternodes doing it not your client, your transaction is near instant (supposedly less than 4 sec IIRC) so you can use Dash at point-of-sale with merchants on your phone etc. Very interesting stuff. Not to mention the social wallets aspect and Dash Storage. I haven’t fully delved into this, but apparently it will do basically the same thing that maidsafe is doing, decentralized storage of files. Obviously in a different way, but that appears to be the goal. But because the Masternode network is already up and running, building all of this shouldn’t take too long theoretically.
