Block chain development: Which FCC courses support this goal?

I’m new to this community, and trying to map out the most efficient learning path towards being a block chain developer.

Which FCC courses should I start with?
Which FCC courses will contribute the most to being block chain competent?
If there are multiple FCC courses that will support my goal, what is an ideal order to take these in?
What other free resources exist that support being a block chain developer?

Deepest gratitude in advance!
