Right, one can do distributed/federated apps w/o blockchain (see email). It's too practical to be exciting
That alone is enough to make me feel sure of my investments. However, there are many beautiful things that will come out of Web3.0 as well. End to end open source VPNs, containerized and running on a decentralized cloud is already a reality. You an use it today for free on Android and IOS (Velocity VPN - Running Sentinel back end.) Its open source and anonymous end to end. No one is keeping logs.
Don't look at the shit coins and the bubble and think the dream of Web3.0 is not real.
Are you saying sentinel is open source, or that Velocity is open source? Because I can't find any velocity repositories on the web, nor is the app on f-droid.
That's a little misleading, the app says it is "free and unlimited while in its testnet phase". Presumably it will require some cryptocoin eventually.
