“…There are already studies that try to model, although indirectly, blockchain data. Some create easy-to-use interfaces, such as HTTP REST interfaces [Li et al 2017, Pratama andMutijarsa 2018] while others provide SQL interfaces that execute on top of native blockchain clients [Linoy et al 2019, Trihinas 2019. Finally, many studies decide to simply copy the data in order to make it accessible through popular database management systems and its interfaces [Peng et al 2019, Bartoletti et al 2017, Bartoletti et al 2017, Han et al 2019, Zhou et al 2019.…”

The popularity of blockchains has been steadily rising since its inception in 2009. Its original focus was the creation of a distributed trustless system for a digital currency. Bitcoin was the first widely used blockchain. However, many more have been further created: Ethereum, Solana, Hyperledger Fabric, to name a few. Due to it, blockchain networks and its properties are being scrutinised by data scientists. This topic is known as blockchain analysis. However, analysis ́ tasks are hard to be accomplished over multiple blockchains. Even though most have similar concepts, each one has its own data modeled differently. As a consequence, scientists end up needing to do rework in order to apply similar analytics and algorithms in more than one blockchain network. In fact, blockchain data modeling is an open issue. This master’s thesis aims at proposing an unified model for blockchain data. For the best of our knowledge, there is no similar work in the literature.

“…Besides, some privacy-preserving schemes that try to leverage 5G technology in blockchain-oriented solutions have been presented [7] , [10] , [11] , [16] , [22] , [26] . We can conclude that more and more researchers are paying attention to solve the privacy issues in 5G-integrated blockchain networks.…”

Privacy-preserving contact tracing in 5G-integrated and blockchain-based medical applications

The current pandemic situation due to COVID-19 is seriously affecting our daily work and life. To block the propagation of infectious diseases, an effective contact tracing mechanism needs to be implemented. Unfortunately, existing schemes have severe privacy issues that jeopardize the identity-privacy and location-privacy for both users and patients. Although some privacy-preserving systems have been proposed, there remain several issues caused by centralization. To mitigate this issues, we propose a P rivacy-preserving contact T racing scheme in 5G-integrated and B lockchain-based M edical applications, named PTBM. In PTBM, the 5G-integrated network is leveraged as the underlying infrastructure where everyone can perform location checking with his mobile phones or even wearable devices connected to 5G network to find whether they have been in possible contact with a diagnosed patient without violating their privacy. A trusted medical center can effectively trace the patients and their corresponding close contacts. Thorough security and performance analysis show that the proposed PTBM scheme achieves privacy protection, traceability, reliability, and authentication, with high computation & communication efficiency and low latency.

Improvement in the requirements for engineering practices is needed in areas such as requirement elicitation, validation, prioritization, and negotiations between stakeholders to create successful projects for COVID-19 (coronavirus disease 2019) software. Many algorithms and techniques are used to create quality software projects, but they still need more improvement to work effectively for global pandemic COVID-19 software. By improving the reliability of requirement engineering practices using blockchain-based technology, the software will be reliable and will make it easier for the users working in a lockdown situation because of COVID-19. Therefore, our purpose is to identify the factors for reliable software engineering practices using blockchain-oriented technology for COVID-19 software. A systematic literature review is conducted to identify challenges and offer solutions. Through using blockchain-based technology for requirement engineering practices, the requirements will be gathered accurately and validated, and the conflicts between stakeholders will also be solved. It will improve the quality and reliability of COVID-19 software projects, which will help society work effectively from home. Improvement in the quality and reliability of COVID-19 software will improve users’ interest, and their working capacity will be increased.
