Researchers at the University of Luxembourg are part of an international team that has proposed the first blockchain system to guarantee proper performance even when more than 51% of the system’s computing power is controlled by an attacker.The system, RepuCoin, introduces the concept of “reputation” to blockchain, effectively making it thousands of times more expensive to attack than Bitcoin. It was developed at the University’s Interdisciplinary Centre for Security, Reliability and Trust, and has the potential to be applied in a number of global sectors including fintech, energy, food supply chains, health care and future 5G telecommunications networks.
