Nasdaq-listed cloud-based software company Epazz Inc has filed a patent for a blockchain solution that will manage the compliance of online sports gambling operators in the United States.

In a regulatory filing, Epazz announced on Wednesday that it has developed a blockchain fantasy sport gambling solution that will keep track of state laws to determine if an individual is in compliance.

Even before the U.S. Supreme Court lifted the federal sports betting ban, Epazz pointed out that operators have to look up to each state law if they are in compliance.

Epazz’ patent application targets compliance management and verification of available funds, according to the company. The company’s cryptocurrency wallet, Zenapay, will verify all the details before an individual is allowed to participate in a transaction, according to the Chicago-based firm.
