Authenticating Transactions and Distributing Data to Peers

During this initial week we will start by looking at how the blockchain data

are shared among nodes in the peer-to-peer network over

the internet and how the interconnectivity of the nodes is managed.

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.

Blockchain Limitations

The blockchain is not a perfect system and indeed has its limitations.

We will explore some of the constraints of the blockchain and address the issues that cause such limitations.

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.
