How secured can one get when using VPN based Blockchain service compare to other VPN apps? I don't see any difference here, many developers just want to make every thing available on blockchain, most of the projects don't count, no one needs them
The difference is that Blockchain-based VPNs will offer an incentive for running a node, whereas traditionally-centralized VPN services do not. Since Blockchain is not meant to be used for everything (especially at handling loads of data at an ever-growing rate), it could serve as a financial layer for the innovative VPN system. Decentralized VPN solutions could adopt innovative cryptographic techniques (ZKPs perhaps?) to stay ahead in the game. Of course, the number of VPNs using Blockchain technology are still experimental and not proven for widespread use. It may take a couple of years from now before we'll be able to grasp the true power of a decentralized VPN service backed by the Blockchain. We already have the Mysterium Network and the Tachyon Protocol, so I'd expect new projects to emerge over time that would make use of Bitcoin's innovative technology for their own benefit.
With many alternative networks available today (such as Tor, Zeronet, i2p, etc.), it's doubtful that a VPN service relying on Blockchain technology will ever succeed in the future. But who knows? Technology is known to evolve over time. As people become aware of the need for privacy, they'll resort to anonymity networks or other privacy solutions to protect themselves against government surveillance. Rest assured, that a decentralized VPN service with an incentive mechanism will surely attract the likes of tech gurus, investors, and everyday people. All in all, I'd recommend anyone to use tried-and-tested privacy solutions like Tor or i2p instead of Blockchain-based VPNs until they become mature for mainstream use. Time will tell us whenever this was just crazy idea (of a VPN using Blockchain technology) or not. Just my opinion
