An Australian computer scientist’s claim to be the mythical figure behind bitcoin will be challenged in the UK on Monday, in a high court case backed by the Twitter co-founder Jack Dorsey. Craig Wright has asserted for years that he is the real Satoshi Nakamoto, the pseudonymous author of the 2008 white paper behind the world’s cornerstone cryptocurrency, but has failed to prove it. The 53-year-old’s claims to be the founding father of bitcoin, and widespread scepticism about these within the crypto community, have led to a number of legal clashes over the years.
