This week we will examine and study the ways that the blockchain keeps track of ownership transactions through the use of electronic ledgers. After an item changes hands many times, one can literally see each handoff by looking at the continuously growing string of data blocks in the blockchain.

The key to the blockchain’s success is the use of hash values and encryption. These are the same technologies that allow you to log into your favorite website without revealing your password and the same technologies that allow you to send a private, encrypted text message. By the end of the week you will apply a hashing algorithm to a character string and see the results.

As you will see in this final week, it is sometimes important to step back from a purely functional discussion of what the blockchain can do to what it means when it does it. You will apply cryptography and hashing to a simple scenario in order to determine the authenticity of a simulated email message.
