On September 28, the California governor signed AB 2658, which requires the Secretary of the Government Operations Agency to appoint a blockchain working group by July 1, 2019. (The act defines blockchain as “a mathematically secured, chronological, and decentralized ledger or database.”) The working group is charged with evaluating, among other things, (i) the risks and benefits associated with the use of blockchain by state government and California-based businesses; (ii) the legal implications of the use of blockchain; and (iv) best practices for enabling blockchain technology to benefit the state and its businesses and residents. The act, which has a sunset date of January 1, 2022, requires the working group to provide a report to the legislature by July 1, 2020.
