Why you should enroll

You will learn both how an attacker might potentially execute an attack, how the network protects against the attack and what the probability of someone executing the different attacks is.

Although this course focuses on Bitcoin you will be able to apply this knowledge to any cryptocurrency or blockchain network because all cryptocurrencies share a similar security model.
