Craig Wright has entered settlement talks with the estate of his former collaborator Dave Kleiman, less than a month after a federal judge issued a sanctions order that may have cost him billions in bitcoin.

U.S. District Judge Beth Bloom granted a joint motion from Wright and Kleiman’s estate in part on Sept. 17, approving their request for an extension of discovery and case deadlines. According to the order, “the parties have been engaged in extensive settlement negotiations and have reached a non-binding agreement in principle to settle this matter.”
