How to be a blockchain developer? I want to be a blockchain developer, any suggestion or help for me?
It's not like you'll attend a seminar and later on you can be one out of it.
Becoming a blockchain developer takes time and you must be knowledgeable with coding and programming language. The first question that I'll ask you is do you have any programming/coding background?
If you do have, you can move to the next level of starting to become a blockchain developer by looking up a training course online(if there is).
I think he should start by studying CS and get a degree in it ~ 4 years
Yes if OP doesn't have that background about basic programming languages, logic, coding and other important computer science subjects better to start and get a CS degree.
