Ethereum founder Vitalik Buterin retweeted a post from the Tor Project. The Tor Project stated in its tweet that the Tor VPN Beta, soft-launched a year ago, aims to extend Tor's privacy protection to the entire Android device. Since its release, they have learned how users interact with the product in real-world scenarios, and introduced its "per-app circuit isolation" distinguishing it from commercial VPNs, user experience lessons learned when bypassing blockades, and the mobile foundation built for the future.
