How can I get an entry level career on blockchain? What do I need to do/study/learn?
What you need to study if you want a career on blockchain is programming languages. Solidity/Python/Java/PHP/Ruby is as far as I know the most used OOP programming languages on Blockchain development but there are still more that can be used.
Correct.
But there's still one other perspective of OP's question in my opinion. I don't know if I'm correct but I think OP were trying to ask if there's a certain courses that teaches majorly in Blockhain and has certificates when finish a degree or vocational course, I think? well if I'm not mistaken, there are just limited countries that offer such thing.
And if OP were trying to ask how he would start his career on Blockhain like trading, he won't need diplomas to that anymore. All he needs is to self study and attends seminars that tackles blockchain topics to receive certificate.
