Thanks for the update .
As far as ideas , do you think it is possible to tie a registered gun owner database to the blockchain ? You could instantly transfer gun ownership at a gun show or private transaction and you would own the private key to the registered serial number on the gun. The ownership database would be public info on the blockchain that anyone could look at. I remember reading somewhere that there is a certain amount of information you can add inside of the blockchain and that would be enough for a gun serial number I think. This could also be an effective way to curb sales of stolen guns because if you cant show that you are the owner of the private key that is registered to that serial number then the gun is not yours. You could market Guncoin this way as a way to track and publicly register gun ownership on the blockchain.
You must not be from the US.... We don't have a registered firearms owners database. The only national thing we have here is NICS (national instant check system) and that system is run by the FBI, and only shows weather or not a person who is trying to buy a gun from a federally licensed dealer (FFL holder) is a prohibited person or not (aka a convicted felon). We don't register our guns here. Face to face transfers between two private people don't require a Form 4473 to be filled out (unless you're from the communist state of New York. Sorry 315er
. State laws do vary, but bans on FTF transfers are hardly enforceable (though ATF agents DO try every once in a while and they ALWAYS say that they're a felon to see if you'll go through with the deal. It's pretty fucking obvious.).
Can't be offended by facts..
We are working hard to repeal the (un)safe act, but the fix is in.. The Governor that forced the bill through illegally in the middle of the night, was re-elected by something like 15 counties when 47 counties voted against him. (going by memory)
He is also being investigated by the federal attorney general for bribary and corruption, but is still talking about a presidential election run in 4 years.
As far as using the blockchain for firearm transfers, it could be used as a record keeper. But would also require some personally identifiable information to be permanently located in the blockchain to show who the transfer was to.
I'm not familiar with laws outside the US, but inside the US laws vary by state, even through there is some federal control. For most states rifles can be sold by f2f transfers, not requiring any paperwork at all. And, most states require a permit to possess a pistol, and exchanges/purchases must be done by a shop with a FFL (Federal Firearm License) to provide the NICS check, record the transaction, and hold the pistol until the purchaser gets it entered into the county or state pistol database.
Crazy laws here.. See a doctor for insomnia issues because of some recent stress, lose your pistol permit, police come and collect whatever firearms they know about. (this happened not far from me)
Even crazier, have the same first and last name as someone else and be somewhere around the same age, and get your permit revoked for doing nothing wrong.. (this also happened not far from me)
