Industries that he mentioned are: healthcare, logistics, insurance, governement and this list goes on. So do you really say that all the requirements that you wrote aren't necessary in this field?
they may be necessary, but that doesn't mean that blockchain is a good solution. Not even that blockchain is a solution.
Then let me tell you that blockchain adds an extra layer of protection to data that's stored and this is especially beneficial for services like these.
Do you think that this "extra layer of protection " is free? Is mining free? Would like to pay extra fees when you buy something in the supermarket and they want to register that in their blockchain?
Would like to pay fees when you make an exam? Because nothing is free in blockchain. You pay for EVERY interaction in a dApp in ethereum network for example.
Blockchain technologies are successfully implemented on land title registry in some countries and this isn't the place where governments plan to stop. In Brazil, as far as I remember they decided to use Blockchain technologies for newborn baby registry.
That information is just false. I live in Brazil and this is not happening. I read something about that, probably just a hyped project which never got out of the paper. Specially here in Brazil where people lack money to buy food, cloths, will people pay extra fees to have babies?
In overall, it's great in such industries, where the transparency and accuracy of information matters and I think there are a lot of like them, especially medicine too.
And, blockchain is slow because of high security and decentralization, it takes a lot of time to process these.
Not only time, but money as well.
We pay fees for transactions not because its fun, because someone has to pay for that processing power.
Edit: Don't get me wrong. I am not bashing bitcoin neither the blockchain. Just explaning how it works and why it is not suitable to be used in EVERYTHING.
Blockchain is not a new free "extra layer of security". It was not designed for that.
