Organizations are testing the potential of blockchain technology in different areas, bringing implications to record-keeping and the business processes associated with it, namely audits. Permissioned, private blockchain frameworks can contribute to the processes behind audits by (i) alleviating auditor’s work, (ii) hindering fraud and collusion between organizations and auditors, (iii) promote synergies between organizations and their stakeholders, and (iv) protecting access to sensitive information. This paper provides pointers to the utilization of the blockchain technology as an enhancer of secure, distributed, and more automatized audits. The proposed solution uses a permissioned, private blockchain to store audit logs. The blockchain is then leveraged to performed distributed and automatic audits over the recorded logs, aiming to reduce costs associated with audits. In particular, the solution is based on a four-layer architecture, namely the data acquisition, data transfer, data audit, and data analysis & storage layers. The evaluation shows that the proposed solution is secure and can save and analyze up to around 30 audit logs per second.
