Consider the study by Yermack (2016) named “Corporate Governance and Blockchains.” Which of the following claims and statements are made by that article?

           I.          Maintaining anonymity has at times proven difficult in the Bitcoin blockchain. Law enforcement officials have successfully identified and prosecuted money launderers, drug dealers, operators of virtual casinos and Ponzi schemes, and other miscreants.

         II.          The first suggestion of blockchain-like structure was introduced in Haber and Stornetta’s (1991) proposal for the digital time stamping of documents in sequence to authenticate authorship of intellectual property, however the first reference to this data structure a “chain of blocks” appears to come from Nakamoto (2008).

       III.          If a company’s shares are traded on an exchange that is built on blockchain, then there will be consequences. For example, blockchain trading of a company’s shares would likely reduce the effectiveness of equity-based management incentives.
