I’m not sure. Mullvad is still a good product, but what it funds is not.

If I’m entirely honest, I mostly see VPN services as a predatory market, inflated by their own marketing campaigns about the risk of personal privacy. There are some products who are true to their word, like Mullvad, but most are looking for a quick buck from the average user who might forget they have a running subscription if they keep the cost low enough.

Frankly, after seeing what’s happened with Proton and Mullvad, I’m not inclined to believe anyone in this market amounts to more than a paranoid libertarian at best.

There was some drama after one of Mullvad’s cofounders was outed for donating considerable sums of money to right wing organizations. It’s fallen out of favour as the default recommendation as a result

A blockchain doesn’t actually provide control over a transaction, it just verifies that it happened. It’s supposed to be a long, immutable record of every transaction that has ever ocurred, which is precisely why transactions can’t be reversed. The work of verifying those transactions is performing by miners, or some other “proof of” design where you have an authority in the chain that confirms it.

Basically, it’s nothing more than a fancy receipt.
