Nevada has become the first state to ban local governments from taxing blockchain use.
This could make Nevada a hub for blockchain startups and it certainly offers agorist opportunities. A brand new law in the state of Nevada creates a free-trade zone for cryptocurrencies and other blockchain applications exempting them from regulations. The law prohibits taxing and regulating blockchain businesses.
In addition to preventing local governments from taxing the use of a blockchain or smart contract (or requiring a licensure for their use), the bill stipulates "if a law requires a record to be in writing, submission of a blockchain which electronically contains the record satisfies the law" – meaning that data from a blockchain can be introduced in "proceedings".
In my opinion this is going to launch Bitcoin into the mainstream in a big way. My nephew was just in Nevada and sent me a picture of a Bitcoin machine in one of the hotel lobby's. This should be a wake up call to those who think cryptocurrency is just a fad.
