 In this module, you learned that random numbers (or, at least, pseudorandom numbers) are essential in cryptography, but it is extremely difficult even for powerful hardware and software to generate them. Go online and conduct research on random number generators. What are the different uses of these tools besides cryptography? How do they work? Explain your answer using your own words in 6-7 paragraphs.

hapter 10 introduced the need and function of governance in a blockchain environment. Create a new thread, choose two aspects of enterprise blockchain governance presented in chapter 10 and describe how you think each one could help govern a blockchain environment (and how it differs from a traditional application environment.) Then think of three questions you’d like to ask other students and add these to the end of your thread. The questions should be taken from material you read in Chapter 10. You’re not trying to test each other, but you are trying to start a discussion.
