I&#x27;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&#x27;s.  Could we eliminate 4473&#x27;s altogether?  Of course, if we&#x27;re actually serious about background checks, we need to fix reporting into NICS system while we&#x27;re at it, among other things.<p>As to the linked proposal, it doesn&#x27;t strike me as very informed… I still fundamentally don&#x27;t understand the infatuation with insurance (other than as a backdoor way to limit ownership).  Insurance may cover acts of negligence, but doesn&#x27;t it exclude suicide&#x2F;suicide attempts and criminal acts, right?  What events are being insured, and who is paying out?
