The Central Bank of Brazil introduces the Pix button to dispute fraud cases, which adds a feature that Satoshi Nakamoto must have been against. The Central Bank of Brazil has developed a new Pix service where fraudulent transactions can be disputed online. According to Breno Lobo, Deputy Head of Competition and Market Structure Department at the Central Bank, the process enhances the possibility of getting stolen money back in time. The Pix dispute button creates some reversibility and centralized intervention. The persistent Pix upgrades by the Central Bank of Brazil are an indication of attempts to strike a balance between innovation and the security of users.
