Australian tech entrepreneur Craig Wright told the BBC on Monday he was the creator of controversial digital currency bitcoin, ending years of speculation about a person who until now has gone by the pseudonym Satoshi Nakamoto.

The BBC said Wright gave technical proof supporting his claim to using bitcoins known to be owned by bitcoin's creator. It said prominent members of the bitcoin community had also confirmed Wright's claim and said Wright repeated the claim to The Economist and GQ.

"I was the main part of it, but other people helped me," the BBC quoted Wright as saying.
