Is there anybody else that uses GPG signed contracts for assets?
A couple of real life registered Bitcoin companies here in the USA that I am involved with have started to do so. Assets are not exactly tradable so I realize that is not what you are really asking. Its pretty crazy to see. Will be showing my lawyers them soon, would really like to know what he thinks about it.
Yeah, I was talking about other online asset trading platforms (havelock, cryptostocks, GLBSE-copy-of-the-week, etc). Some might not remember, but GLBSE originally used GPG signed contracts; unfortunately there was no moderation as to what went into them. Later the gpg signatures were eliminated to make it more user friendly, before it was suddenly shut down.
I suspect we will see the use of gpg signatures grow in the business world. Adding them is a simple thing to do (once you spend just a little time learning how), and they are a great way of certifying a document, especially when dealing with distant people, sort of the modern version of having your documents witnessed by a notary.
