## 1 Introduction
In other words, due to the fact that companies are obligated to pay SG on a quarterly basis, whereas salaries are often paid weekly, fortnightly, or monthly, employees are unable to depend on their pay slip to ensure that their SG has been paid [21]. Moreover, some employees find out that their super has not been paid when they file an insurance claim [15]. Furthermore, the issue of accurately determining the level of SG non-payment in Australia has been emphasized by The Senate Economics References Committee (SERC) [12]. Due to numerous data gaps, it is a challenging task to accurately estimate the extent of SG non-payment. It is vital to obtain the opinion of a responsible person from the ATO to confirm the degree of success of the aforementioned processes, even though there are ideas and procedures implemented to identify SG non-payments. Mr. [PERSON] [12], the ATO Deputy Commissioner responsible for Superannuation, stated,  
_\"In relation to the SG gap, effectively most of last year, as certainly many stakeholders knew, we have been progressing to develop a credible and reliable methodology to determine the SG gap. We certainly had been working through an appropriate methodology, but at this stage, as is I think on the public record, we do not feel we have a reliable one, that we have a high enough level of confidence\"._ [12]  
This statement was made according to data provided by the federal government, during the six-month amnesty that ended on 7 September 2020. This highlights the critical need to address the issue of unpaid superannuation and develop more effective and efficient systems for detecting and preventing non-payment, thereby ensuring the financial security of Australian workers. Even though it is a major liability for employers, and superannuation contributions are essential for ensuring the financial security of employees, the timely payment of superannuation contributions by employers to employees' super funds is not always guaranteed, which highlights the need for a robust system that enables both employees and the government (ATO) to detect unpaid contributions and take appropriate action. It is evident that there has been a significant upsurge in the use of technology to detect fraud in various industries. In fact, a novel AI-/ML-based system called the Anti-fraud-Tensorlink4 cheque (AFTL4C) has been developed to recognize fraudulent cheque fraud, which has become a significant problem for financial organizations, causing millions of dollars in losses as a result of illicit activity [22]. Moreover, National Payment Switches (NPSs), which are directly owned by Central Banks (CBs), are rapidly embracing the latest technologies to improve their fraud detection capacities in each of their respective nations [23]. Furthermore, studies point out that molecular genetics and electronic monitoring technology can be used to develop solutions to problems including food security, prohibited fishing, and depleting fisheries resources through fishery surveillance and seafood traceability [24]. Additionally, data were analyzed using MS Excel, VOS-viewer, and Bibliometrix (Biblioshinny) in a study on food fraud to find the most affected countries and food products [25]. In addition, it can be seen that automated tools such as fraud detection software, artificial intelligence (AI) algorithms and blockchain have been used in the detection of financial fraud [26]. Prior studies have noted the use of technology for fraud prevention and user acceptance. The literature highlights frauds relating to super funds across the globe. However, it sheds limited light on blockchain-based applications for preventing superannuation fraud. Therefore, based on the successful application of technology-based solutions for fraud prevention, this study reviews the role of blockchain technology in improving transparency and presents a blockchain-based solution to prevent superannuation fraud in Australia.
