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.

Frequently asked questions
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work.
