At a convention on digital currency, rarely does an audience Q&A session include a question as incendiary as, “Why is this fraud allowed to speak at this conference?” But that’s how a discussion about Bitcoin ended up last year in Seoul.

The supposed fraud is Craig Wright, an Australian-born technologist who gained notoriety three years ago when he declared himself the inventor of Bitcoin. The provocateur is Vitalik Buterin, a baby-faced Russian-Canadian programmer who helped create another popular digital currency called Ether. No one disputes Buterin’s role in Ether; many reject Wright’s claim to be Satoshi Nakamoto, the mysterious genius behind Bitcoin.
