Few issues in financial policy are more controversial than the impact of blockchain, the distributed ledger technology that sits behind the digital currency bitcoin. Does it threaten not only the profits of financial intermediaries but also their business models? Could it undermine the control that central bankers exert over global payments and securities processing? Or is it a tool to streamline cluttered processes, improve resilience and enhance transparency?

Broad-based adoption could take as long as a decade, as issues such as scalability and standards have yet to be resolved. And while there is a great deal of hype surrounding the technology, there are also several misconceptions.
