I'd start with the basic education and then get as deep as possible in technical specifics.
Education:
- Learn everything there is to know about Blockchain technology
- Understand how different types of companies use the blockchain for different uses
- Understand how companies could use your help, i.e., what part of the strategy, design, proof of concept, testing,
and implementation/deployment do companies usually struggle with? - Read up on the industry trends and news, you'll need to the latest goings on
Technical:
- How are business requirements turned into developed code
- How is a blockchain built, accessed, operated, deployed, etc.
Get experience any way you can to build the technical skills. Be an intern, work for a blockhain company, find educational courses.
Good luck to you. Let us know how it goes!
