Australian tech entrepreneur Craig Wright has told the BBC he was the creator of controversial digital currency Bitcoin, ending years of speculation about a person who until now has gone by the name of Satoshi Nakamoto.
The BBC said Mr 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 Mr Wright's claim and said he repeated the claim to The Economist and GQ.
"I was the main part of it, but other people helped me," the BBC quoted Mr Wright as saying.
Last year he became the latest in a line of men alleged to be the creator of Bitcoin, a currency that has attracted the interest of banks, speculators, criminals and regulators.
Wired magazine, which along with fellow US publication Gizmodo published a story outing Mr Wright based on a stash of leaked documents and emails, called him a genius.
