hi, pleased you are writing an article, I have made a list of some of the unique points that may help,
1) The masternode network supports around 2700 full nodes that keep the network seeded with strong peers and coupled with a small blockchain size(<1 gigabyte size) result in a fast sync time of around 0.24 seconds per hour behind in wallet. I call this the Tao ratio and have been tracking it and comparing to bitcoin as both develop, with each new release the tao sync ratio has reduced indicating efficient streamlined programming (last darkcoin release v0.11.1.25 = 1.35 seconds per hour behind)

The recent bitcoin mining fork caused by a pool only mining the headers using the SPV (multibit) wallet is an example of the importance of full clients running on the network, when the client is lite to begin with, there is no need to have a multibit wallet for most purposes, hence the network should not fork.
2) the masternode network has a proof of service test scoring system in order to stay on the network as a paid node. This ensures that all the active nodes are fast, stable and stay online 24/7 thus ensuring a reliable speedy network.
3) The masternode's true potential has not been realized yet as an example, I believe the whatsapp network had roughly 1000 computers with a capacity of 1 million messages per second.
Encrypted wallet to wallet messaging is one of a number ideas that have been suggested, hence there is one of the fastest messaging systems on the planet just waiting to happen.
4) In version 12 of the wallet release, development projects are going to be proposeable (by anybody) and the masternode holder will have 1 vote each that will decide whether a project is going to be funded from the mining output. Meaning that once the vote consensus reaches 51%(of the 2700 nodes), the programmer will get paid once per month from a percentage of the mining output - in a completely decentralized way that has no central point of control.
5) InstantX - using the instantX wallet feature, transactions are locked by the masternodes within around 4 seconds, guaranteeing the recipient will be paid, when an exchange chooses to use this feature, deposits should be reduced to a few seconds.
It is noted that a number of sites do not wait 1 confirmation of bitcoin, thus they are opening themselves up to a double spend hack, this can not happen if they used the instantX feature as the transaction is locked for payment (it also excludes the payment being sent on again by the recipient, until the normal proof of work has taken place)
6) Darksend - ability to send transactions anonymously but still be visible in the blockchain. Again the masternodes come into their own, facilitating a coin mixing service that basically mixes up all your own change addresses by sending the coins around the network in a random way (2 rounds is lowest security, and 8 rounds is maximum security, although 16 round has been tested).
(It is well known that companies like coinbase have been closing accounts because they do not 'like' the transaction history)
7) the protocol is the same as bitcoin, so feature developments will be compatible.
