This is the list of cryptocurrency projects that have source code of the main components written from ground up: eg: no fork, no clone, and not built on top of a specific project such as bitcoin.
I put it here to remind all of us that build a cryptocurrency from scratch is incredibly hard. So creators and developers are working hard on it are worthy a lot of praise.
Thank you to https://twitter.com/cryptic_monk?s=09 who had the first idea and research data on coins built from the scratch and @johntromp
In this list, whoever the author, who has taken so much headache to study and collect data, many great thanks. Until now there are only 98 or 99 coins built from scratch.
