As security researcher Dan Kaminsky explains, Bitcoin looks like a security nightmare on paper. A C++ code base with a custom binary protocol powers nodes connected to the Internet while holding e-cash, sounds like a recipe for disaster. C++ programs are often riddled with memory corruption bugs. When they are connecting to the Internet, this creates vulnerabilities exploitable by remote attackers. E-cash gives an immediate payoff to any attacker clever enough to discover and exploit such a vulnerability. Fortunately, Bitcoin’s implementation has proven very resilient to attacks thus far, with some exceptions. In August 2010, a bug where the sum of two outputs overflowed to a negative number allowed attackers to create two outputs of 92233720368.54 coins from an input of 0.50 coins. More recently, massive vulnerabilities such as the heartbleed bug have been discovered in the OpenSSL libraries. These vulnerabilities have one thing in common, they happened because languages like C and C++ do not perform any checks on the operations they perform. For the sake of efficiency, they may access random parts of the memory, add integers larger than natively supported, etc. While these vulnerabilities have spared Bitcoin, they do no not bode well for the security of the system.

Node software still isn't ported to Rust? There's no way all nodes use the same node software

C++ is a security nightmare on its own

8.82 years ago i met in an Ottawa gay club a man called Dr Sòy Nzagraerav.
After a few drinks, we decided to move into a more private place, so he invited me at his condo.
He was very drunk, so he grabbed a piece of paper and he started to draw something, he told me about this project: to merge several gay men into one single organism, by stitching their anuses and mouths together.
I was very scared, but he continued: "i dream about a chain of gay men linked together, it's not about money, i want to achieve the ultimate thrill!!!".
I poured him an entire bottle of Minttu, then two, hoping to loose his consciousness, but the more he drank, the more he seemed to be hyped.
I had to hit him with a big raw Sandy Brown i found in his bathroom, i ran away.
