Blockchain has the potential to transform audit and assurance activities by introducing efficiency and transparency. Since blockchain creates a tamper-proof and immutable record of transactions:
Continuous Audit: Auditors can perform ongoing audits using real-time data rather than periodic checks, enhancing the timeliness and reliability of assurance activities.
Automated Validation: Blockchain reduces the need for manual verification as transactions are automatically validated by consensus mechanisms.
Complex Protocols: Blockchain introduces complex protocols that auditors need to understand to evaluate and verify transactions.
Smart Contracts: Auditors must develop programming skills to understand the terms and conditions embedded in smart contracts, as these dictate transaction execution and compliance.
Data Sufficiency: While blockchain records transactions immutably, it may not provide sufficient contextual information for auditors to assess legality, fraud, or authorization.
Specialized Skills: Auditors with expertise in blockchain technology and smart contracts will be in high demand.
Multidisciplinary Teams: Audit firms may combine IT, accounting, and legal expertise to manage blockchain-related audits effectively.
Role Evolution: Auditors will transition from traditional tasks to providing assurance over blockchain systems, ensuring the integrity of underlying smart contracts and compliance.
Blockchain enables continuous auditing, allowing auditors to:
Monitor transactions and controls in real time.
Test both routine transactions and violation scenarios against pre-defined business rules within smart contracts.
Blockchain is set to reshape auditing by automating verification, enhancing transparency, and reducing fraud risks, but it also demands a significant upgrade in auditors' technical expertise.
