Delaware is will soon have a blockchain law, though the process is in the early stages. A piece of legislation would change the state's General Corporation Law to allow for blockchains.
The Delaware Blockchain Initiative is supported by Symbiont, and 2017 is the year that it is supposed to happen. The bill states, "Amendments to Sections 219, 224 and 232 and related provisions are intended to provide specific statutory authority for Delaware corporations to use networks of electronic databases (examples of which are described currently as 'distributed ledgers' or a 'blockchain') for the creation and maintenance of corporate records, including the corporation’s stock ledger."
According to law firm Richards, Layton and Finger, the bill is will need more support from the Corporation Law Section and also need introduction to the Delaware General Assembly (the state's legislature). However it could happen as soon as August.
