The most pro-gun state in the U.S. has apparently been blocked in its latest attempt to muzzle new blockchain-based technologies which could make gun owners accountable for every shot they fire.

The bill was introduced last month by Arizona state representative Paul Boyer, and seemed set to pass through legislative hurdles with ease until hitting an abrupt roadblock when the Senate Government Committee chose to freeze the bill and halt its further progress.

House Bill 2216 aims to prevent the possible introduction of tracking systems which communicate ledger entries to a blockchain system when a suitably-enabled weapon is discharged. Proposed section 13-3122 would read:

‘It is unlawful to require a person to use or be subject to electronic firearm tracking technology or to disclose any identifiable information about the person or the person’s firearm for the purpose of using electronic firearm tracking technology.’

The addition is not intended to be applicable for law enforcement officers or for those who voluntarily subscribe to such a tracking scheme. Persons or entities enabling such technologies would be liable to 1-5 years’ imprisonment under the legislation, and a fine of up to $2,500.

According to Guns And Ammo, Arizona is the premier state in the union for gun-lovers, boasting an ‘unmatched shooting culture and strong industry presence’.

In a climate where eight years was not enough time for President Obama to make any headway on America’s devotion to its domestic weaponry, and where the current president seems likely to undermine such control as there already was, lobbying concerns such as the National Rifle Association tend to abreact at any fledgling hint of increased gun monitoring.

Intelligent authorisation technologies are beginning to gain ground and commercial interest, enabling what has been to date a science-fictional concept (notably in various incarnations of Judge Dredd). BioFire Technologies is developing guns which require personalised fingerprint access to operate; Safe Gun Technology Co. is creating kits capable of retrofitting ‘dumb guns’; and iGun Technology Corp eschews fingerprint ID in favour of RFID recognition of a ring worn by the shooter.

A smart gun created by the New Jersey Institute of Technology employs biometrics to verify the authorised user via their unique grip style and pressure via Dynamic Grip Recognition.

Bolting on the kind of blockchain registry that Paul Boyer has been opposing would be a relatively trivial matter once any digital authorisation system is in place.
