The U.S. Securities and Exchange Commission has dropped a three-year investigation into blockchain software developer Hiro Systems (formerly Blockstack), which raised $70 million in token sales between 2017 and 2019, according to a filing. “Based on the information currently available to us, we do not plan to recommend that the Commission bring an enforcement action against Hiro Systems PBC (formerly Blockstack PBC),” the SEC’s enforcement division said in a letter to Hiro included in an attachment to Friday’s filing.
