He supported me when I needed it. There are times when things were very difficult and Dave was my friend in those times. They ran a node or two for some time and later helped me with some of the scaling research I was doing.
Dave helped more in other areas than bitcoin. When it comes to bitcoin, there were many external people. All of them helped. One area that I did not do anything on was IRC. I am much more of a hothead. So here, when talking to a few people Dave would send received permission. On top of this as people will start to figure out both of us used similar connections to systems like Liberty reserve to load monitoring software.
When it came to scaling tests and some other work, Dave sourced people. All of this was conducted on a commercial basis. Contrary to what some people think I don’t have partnerships and never will.
