The researchers believe it affects all VPN applications when they’re connected to a hostile network and that there are no ways to prevent such attacks except when the user’s VPN runs on Linux or Android.

The blockchain’s use of decentralization is pretty much a security measure. If you want to rule out the blockchain entirely, you’d still need to address the immutable and transpartent components. Only using one block once published moving forward is quite different than the fediverse. Then there’s smart contracts too. It’s a massive improvement to various current online platforms, to say it’s merely decentralization is highly misleading.

Edit: So far, web 3.0 has yet to impress me and I’d be surprised if it does anytime soon. But blockchain tech is not simplistic and can be setup for anonymity as well.

It’s more closely related to the initial intentions of the internet than most other social platforms. Ideally it could get things going back in the right direction again iif nothing else!
