Frenchman whistleblower Hervé Falciani, the ex-mole of tax evaders, officially presented his blockchain-based project aiming to fight fraud and money laundering. The former UBS senior system engineer, who published the 'top secret' list of tax evaders that had financial accounts at the branches of the Swiss bank in the 2008 Valencia Polytechnic University bang, went in exile in the city of Madrid, Spain. Falciani became famous as the HSBC former employee.
