This weeks reading introduced an overview of blockchain security. Create a new thread, and describe how you would go about ensuring the security of data stored on a public blockchain. Assume that your blockchain app is one that manages prescription drugs for individual patients. Considering each of the elements of the CIA triad, describe how you might protect the blockchain data security. Then think of three questions youd like to ask other students and add these to the end of your thread. The questions should be taken from material you read or videos you watched from this weeks assigned activities.
