To become a Blockchain Developer I would suggest you start by getting a degree in Computer Science, IT, or any related field. Master programming languages like Python, Java, C++, Ruby, etc. Learn and master cryptography, blockchain architecture, Data structures, smart contracts, etc. Once you feel you are confident about basics or foundational knowledge, then check out the Blockchain Training course from Intellipaat. I will also share a video of a customer who took this course and upskilled successfully.
