I've long wondered if, in addition to opening up the NICS system to private individuals for private transactions, the blockchain could be used to demonstrate that a background check was performed without the hassles of dealing with an FFL or the negatives of storing 4473's. Could we eliminate 4473's altogether? Of course, if we're actually serious about background checks, we need to fix reporting into NICS system while we're at it, among other things. As to the linked proposal, it doesn't strike me as very informed… I still fundamentally don't understand the infatuation with insurance (other than as a backdoor way to limit ownership). Insurance may cover acts of negligence, but doesn't it exclude suicide/suicide attempts and criminal acts, right? What events are being insured, and who is paying out?
