Chinese scientists have developed a new blockchain storage technology that they say can resist attacks from quantum computers. Blockchain technology – which provides a shared, decentralised digital ledger that stores tamper-proof records – has shown revolutionary potential in areas like financial services and supply chain management. Usually, blockchains use specialised encryption algorithms to verify each transaction, ensure the ledger’s security, and provide transparent access to data. “However, the rise of quantum computers threatens to break today’s blockchain security systems,” said Wu Tong, an associate professor with the University of Science and Technology Beijing. “Even the most advanced methods struggle against quantum attacks.” Wu worked with a team from the Beijing Institute of Technology and Guilin University of Electronic Technology to find a solution to the problem. They came up with EQAS – or efficient quantum-resistant authentication storage – which the team outlined in the Chinese-language Journal of Software in early June. Current mainstream security methods rely on complex mathematical problems like large-number factorisation, but quantum computers can easily solve those problems using algorithms.
