Q2031059 Inglês
     

      There are still many unknowns with respect to how blockchain will impact the audit and assurance profession, including the speed with which it will do so. Blockchain is already impacting Certified Public Accountant (CPA) auditors of those organizations using blockchain to record transactions and the rate of adoption is expected to continue to increase. However, in the immediate future, blockchain technology will not replace financial reporting and financial statement auditing. Financial statements reflect management assertions, including estimates, many of which cannot be easily summarized or calculated in a blockchain.
           Furthermore, the process of an independent audit of financial statements enhances the trust that is crucial for the effective functioning of the capital markets system. Any erosion of this trust may damage an entity’s reputation, stock price and shareholder value, and can result in fines, penalties, or loss of assets. Users of financial statements expect CPA auditors to perform an independent audit of the financial statements using their professional skepticism. CPA auditors conclude whether they have obtained reasonable assurance that the financial statements of an entity, taken as a whole, are free from material misstatement, whether due to fraud or error. A blockchain is unlikely to replace these judgments by a financial statement auditor.
       That said, CPA auditors need to monitor developments in blockchain technology—it will impact clients’ information technology systems. CPA auditors will need to be conversant with the basics of blockchain technology and work with experts to audit the complex technical risks associated with blockchain.
         In addition, CPA auditors should be aware of opportunities to leverage their clients' adoption of blockchain technology to improve data gathering during the audit. They should also consider whether blockchain technology will allow them to create automated audit routines. The auditing profession must embrace and "lean in" to the opportunities and challenges from widespread blockchain adoption. CPA auditors and assurance providers are encouraged to monitor developments in blockchain technology because they have an opportunity to evolve, learn, and capitalize on their already proven ability to adapt to the needs of a rapidly changing business world.
