Arizona Governor Doug Ducey has signed a bill that aims to prohibit firearm tracking using blockchain and other technologies.

Filed by an Arizona state representative Paul Boyer in January this year, House Bill 2216 seeks to prohibit anyone from using blockchain or distributed ledger technology (DLT) to track any identifiable information on firearms. Law enforcement and other entities are, however, exempted.

The bill covers potential technologies that can be used for gun-tracking under the term "electronic firearm tracking technology", and explains:

"For the purposes of this section, 'Electronic Firearm Tracking Technology' means a platform, system or group of systems or devices that uses a shared ledger, distributed ledger or block chain technology or similar form of technology or electronic database for the purpose of storing information in a decentralized or centralized way, that is not owned or controlled by any single person or entity and that is used to locate or control the use of a firearm."

According to public records, the senate passed the bill earlier this month by 17-12 vote, CoinDesk reported. Earlier this week, the House gave the measure its nod with 34-24 vote. Thereafter, the bill was sent to Governor Ducey, who signed it into law on 18 April 2017.

Last month, Governor Ducey signed the bill HB 2417 into law, which recognizes blockchain signatures and smart contracts under state law.
