Cryptography can be used to hide something, or prove something. The word cryptography encapsulates two different disciplines, cryptography and provegraphy. People who use the term crypto-* to refer to blockchain, do not know that blockchain has nothing to do with hiding information, but it has everything to do with proving information.
So the question becomes, what information are you interested on proving to someone on the internet? Say you want to ask an Israeli on Twitter about some bomb stuff and you want to prove you are a reporter. Say you want to prove in a comment on HN, that a repository on github is yours.
However one problem arises. The digital identity or identities, have to be stored somewhere. What happens if there is an outage? OpenAI had a multiple hour outage just today, and an ISP in Australia had a 12 hour outage yesterday. In that case, people cannot prove digitally their identity or identities (hundred of them if they like), even in real life.
The Greek government requires for the digital identity to be proven, access to internet[1]. I was just researching that right now.
Last, Estonia tries to secure the digital identities of their citizens on the blockchain[2]. Why digital identities need to be secured on a blockchain? Just a server or two, in a government building are not enough? How could a globally competitive network of miners, each one holding the digital information independent of any other, be more secure than the one or two servers solution?
