Blockchain itself is just, at its core, a method of cryptographically proving the authenticity of a ledger history. That’s it. What you DO with that technology is fairly boundless. You can embed anything in a block on the chain. We have lots of existing ways to handle proof of identity that can be inserted into a block (imagine if blocks contained the public key of block’s creator and then the entire block (including the public key) is signed with the private key)
Sure, you could do that, but all that would prove is that a block was signed with the private key associated with the included public key. That doesn’t necessarily say anything about someone’s identity though does it? It just says they know how to generate a public/private key pair and a digital signature. Maybe I’m misunderstanding your example?
