Introduction to Secret Sharing from First Principles - Stoffel - MPC Made Simple
I recently wrote this introduction to secret sharing article. I found that existing ones are either too academic or they simply go through a worked example; neither of which help to develop an intuition as to why secret sharing works. I attempted to write one in such a way that you aren't simply fed the formulas alongside a worked example but that you try to get an intuition as to why this works.
