I like your article! In my opinion, and I may be completely wrong so please take this with a grain of salt, the benefits to TrustPlus's Automatic Transactions that led me to invest in this coin are the following:
Firstly, when it comes right down to it, security and anonymity rely on a game of numbers. That is, anonymity relies on obscurity and security relies on the ability to maintain a secret. The fact that TrustPlus generates automatic transactions means that, without a doubt, they are contributing to the obscurity of all transactions and therefore their potential for anonymity and security.
In/of my own account I have already seen at least 23 automatic transactions for my 10 or so real transactions. This means that, already this early in the game, the chance of finding one of my real transactions, amid all the transactions associated with my address, are 10 in 33, or ~ 30%.
You might say that a 30% chance of finding something is still a pretty good chance, so how can TrustPlus be better?
Well, some people like to compare anonymity to finding a needle in a haystack. So what would it take to make my real transactions at least as hard to find as a needle in a haystack? (Even though the Mythbusters already made this colloquialism obsolete: Episode 23 – "Bug Bomb , Talking to Plants , Needle in a Haystack"
http://en.wikipedia.org/wiki/MythBusters_(2004_season)#Needle_in_a_Haystack)
To answer that question you need to quantify the number of needles and the denseness of the haystack with respect to the needles.
To that end I would like to refer you to this fun paper by Bruno Jedynak and Damianos Karakos,
http://cis.jhu.edu/~bruno/JedynakKarakosSPL.pdf (though their motivation originated from their interest in an algorithm for tracking roads in satellite images).
I will let the reader review their detailed conclusion, but basically, for the case of TrustPlus anonymity will depend on the frequency of generation of automatic transactions.
Secondly, the security of my transaction can only be enhanced by the amount of anonymity associated with all my transactions! That is, if I want to keep my transaction secret, it is up to me to share the fact that there was even a real transaction to begin with, the fact that I trust any other addresses at all, and further which addresses I trust; else, you might never even know to look for that transaction amid all the clutter!! (ie. do you even know that there is a needle in the haystack and how to distinguish the needle from the hay!)
Thirdly, I like their solution to the block chain bloat problem that is plaguing the crypto coin community. I know that, so far, the answer to this question has been, "hard drives will get bigger", (though some are trying to get more creative) but really, do you as a customer want to carry with the entire history of all transactions ever!! I certainly don't. For me, there needs to be a certain amount of trust associated with reducing the amount of history (I call this baggage) you carry around with you. Therefore, if the system is already requiring trust in the automatic transactions, it follows that it may potentially also be trusted when the time comes to transition to a new history of transactions. I am sure that you can keep the old history for archival purposes if you are so inclined, but the beauty of it is that you are not required to!!!
Thoughts, and/or comments?! Oh, and please correct me if I am wrong, I am always looking forward to learning more about the vibrant crypto coin community!
