Blockchain is the financial industry latest disruptor. Many startups are using the digital-currency technology to tackle financial companies’ slow, antiquated back-office operations. For banks, the blockchain has the potential to become a technology model for a low-cost and transparent transaction infrastructure.But not only startups are embracing the revolutionary potential of the blockchain and other digital innovations, so are regulators like ESMA. They’ve just started a call to hear from all those involved, from existing financial institutions to startups and investors. Pretty cool.
