Essay on security-related risks of block chain

The topic you chose to report on is Block Chain. Please prepare to expand upon this should cover the following: 

o    Before you describe the security risks, please do some research into how block chain is secured ? You can get a little technical here but be sure to describe any technical details in a way that business professionals will understand and then describe what are the security risks?

o    Next, the following two articles were published in recent editions of the ISACA Journal. Use these articles as a starting point to discuss some of the security weaknesses of block chain?

o    A-View-of-Blockchain-Technology-From-the-Information-Security-Radar 
o    Blockchain-Identifying-Risk-on-the-Road-to-Distributed-Ledgers 

•    These articles are written from the perspective of an IT auditor, so my expectation is NOT that you simply describe to the class the content of the articles; instead, use these (and any other articles you find) to describe why this is an important topic for accountants (auditors, corporate accountants)? what should  the  auditors do in the blockchain security risks (audit objectives)? 

o You should very explicitly address the relation between blockchain security risks and accounting/auditing processes and information. 

The primary focus will be on  security-related risks of block chain.
