Who is Yonatan Sompolinsky and what did he write about Kaspa?

Yonatan Sompolinsky (@hashdag) is one of Kaspa's theoreticians who wrote a series of Medium posts explaining the philosophy, history, basics, and tradeoffs behind Kaspa. A theoretician is someone who works on the foundational ideas and math that a project is built on — in Kaspa's case, that includes the consensus protocol and design decisions. His posts are aimed at anyone who wants to understand not just what Kaspa does, but why it was built the way it was. For a beginner, reading his writing is one of the best ways to get a grounded, first-hand picture of Kaspa's origins and goals straight from one of its architects.
