Yeah, the internet is, but what I'd envision would be separate intranets who could communicate to each other if they want. So Brazil could talk to India, but they wouldn't have to. The block chains could be transparent to trusted systems and opaque to other intranets. Block chain also could be more similar to Elastic Search DB or Mongo DB, where it takes a majority of servers to confirm the validity of a tramsaction before solidifying a change

Just tossing the idea out there

Most people who shit on "blockchain" don't grasp the nuances. For instance, a hashsums can verify a piece of code is valid, but who's providing the hashsum? If it's on the same server, how do we trust it? If it's on a validator's server, who is validating that validator? This is a fundamental problem in computer science and blockchain is one of the solutions

I shit on blockchain because there's high probability of a backdoor in 90% of all computers and most software is vulnerable, so even if the blockchain isn't vulnerable directly, it most likely is on a different level
