In the last few months I’ve been approached by several different groups in the virtual currency space asking for my input on various things; mostly because of my involvement in payment systems over the last 15 years, but also because I’ve been involved with Bitcoin almost from its beginning. My advice has spanned technical, business, and even legal issues pertaining to virtual currencies; unfortunately, security hasn’t really been given the attention it needs.
The start of 2014, and much of Bitcoin’s existence, has been plagued by security breeches with several Bitcoin related sites falling victim to thefts. As a result I’ve decided to put together a reasonably short document on securing virtual currency applications. It is based on my experience from working at banks and payment processors since the late 90’s and is centred around existing standards and policies such as PCI, OWASP, NIST, etc…. The information has always been out there but application developers (sadly) aren’t normally thinking about security. ‘Throwing a firewall’ in front of it just won’t cut it; especially when it means a compromise could cost you the contents of your hot wallet and your dignity, if you are lucky.
It is titled Virtual Currency Application Security and it is available on Github. It is a work in progress and will evolve, please feel free to provide feedback.
I'm an idea developer. I'm also the Co-Founder, CTO of Redfall Technologies and Vogogo.com. I design and implement online payment systems, specifically online wallets, NACHA, Canadian Payments Association and credit card processing. I also dabble in all things technical.

Silly this has to be mentioned, but be humble. Don’t run your mouth on forums talking about how superior your service/application/product is. It only isolates the community further and no good can come from it. In fact if you set yourself up as an ass people will come out of the woodwork just to take a run at you. You have everything to lose and they have everything to gain.

On the humorous side, your ‘blowhard’ statement reminds me of something a friend once said “Nobody likes a mediocre show off.”
