DOI: 10.1007/s10203-024-00458-w

Abstract: The process of mining blocks on a blockchain utilizing a Proof-of-Work consensus mechanism carries inherent risks, particularly when the operational expenses associated with mining exceed the rewards earned. Building on previous findings on mining in… read more here.

DOI: 10.1109/access.2023.3234322

Abstract: Blockchain (BC) technology has been established in 2009 by Nakamoto, using the Proof-of-Work (PoW) to reach consensus in public permissionless networks (Praveen et al., 2020). Since then, several consensus algorithms were proposed to provide equal… read more here.

DOI: 10.1109/access.2024.3521426

Abstract: In the area of blockchain, numerous methods have been proposed for suppressing intentional forks by attackers more effectively than the random rule. However, all of them, except for the random rule, require major updates such… read more here.

DOI: 10.1109/tnsm.2022.3219494

Abstract: Blockchain-powered smart systems deployed in different industrial applications promise operational efficiencies and improved yields, while significantly mitigating cybersecurity risks. Tradeoffs between availability and security arise at implementation, however, triggered by the additional resources (e.g., memory… read more here.

DOI: 10.3390/sym14030609

Abstract: In blockchains, the principle of proof-of-work (PoW) is used to compute a complex mathematical problem. The computation complexity is governed by the difficulty, adjusted periodically to control the rate at which new blocks are created.… read more here.
