## Summary

This is the white paper of Ouroboros, which is presented as a particularly secure proof-of-stake cryptocurrency. It addresses many different attacks and explains how the Ouroboros protocol can prevent them.

## Comments

Pretty long and hard to read (over 60 pages of thick information and heavy maths). It seems very serious, but it’s too complicated. If few people can understand it, few people will invest. Their cryptocurrency is not used all that much, too. Source : https://coinmarketcap.com
