Craig Wright, the self-proclaimed Satoshi Nakamoto, has filed a lawsuit in the U.K. against BTC Core and Square, the payments company founded by Jack Dorsey. The lawsuit's purpose is not yet known, but Wright is representing himself without legal counsel. Wright has a history of making controversial claims about his involvement in the creation of Bitcoin, and he has been sued multiple times in the past. In 2019, he was ordered to pay $4 billion to the estate of the late David Kleiman, who he claimed was his business partner in the Bitcoin venture. Wright's lawsuit against BTC Core and Square is likely to be closely watched by the cryptocurrency community. If he is successful, it could have a significant impact on the future of Bitcoin.
