According to PANews, Vitalik Buterin, the co-founder of Ethereum, has been interacting with Railgun on a monthly basis using small amounts of ETH over the past six months. This information was in response to a report by Wu. Buterin stated that Railgun uses a privacy pool protocol that effectively prevents malicious actors from joining and protects user privacy. Railgun is a privacy protocol that allows users to make transactions on the Ethereum network without revealing their identity or the amount of their transaction. Buterin's regular interaction with Railgun demonstrates his support for privacy protocols on the Ethereum network.
