The flagship Sentinel dVPN mobile application is returning soon with a completely free version of the application as well as a paid version of the application. The previous free Sentinel Android dVPN on ETH reached over 500k downloads in 2020- early 2021. The upcoming hub upgrade includes major revisions to the networking protocol layer allowing for users to get access to multiple paid nodes with just one payment without the requirement of locking tokens with each node. In addition 'digital subscriptions' have the ability to authorize a user's account on Sentinel to utilize bandwidth from a subscription for free allowing for completely decentralized free VPN provision. This upgrade will enable the fast creation of white-labels and eliminate the issues faced in the past with regards to user-friendly payment structures.
