Determining the Canonical Version of a Blockchain
We will continue to look more closely at how nodes add blocks to the data structure with the goal of maintaining a consistent transaction history. We’ll also see that multiple histories can sometimes arise due to a variety of factors ranging from benign, but unpredictable, node outages to intentional malfeasance. This requires that the system have a means of collectively determining which single history is the correct one. We’ll explore two approaches to achieve this: the longest chain criterion and the heaviest chain criterion and practice applying the principles that we have learned in this week’s assignment.

Organizational Applications of Blockchain
We will finish the course by exploring other opportunities for using a blockchain approach to decentralize what have been heretofore centralized industries in which individual entities have controlled or consolidated information. We will develop ideas for applying a blockchain approach to industries other than cryptofinance.
