US House Republican leader Kevin McCarthy recently wrote in the New York Times that due to lack of flexibility, governments and regulators are clearly unable to adapt to the fast-growing technology sector, effectively protecting citizens from platforms such as Facebook and Google. And the sale of user data, those who are concerned about online privacy security should consider turning to decentralized technology. McCarthy believes that on most current network platforms, user data is controlled by the platform, and users are vulnerable to "privacy violations." In a decentralized network, user data is encrypted on the blockchain, which allows users to control access to their information and does not need to trust third parties. McCarthy said blockchain technology can provide greater data security, portability and privacy for each user, so blockchain privacy can be used as an alternative to overseeing large technology companies.
