Quantum computers,which substantially exceed traditional computing speed and data processing capacity,are gradually moving from theory toward practice.The tremendous computing power of quantum computers will bring fundamental challenges to current information encryption mechanism.Two key applications of quantum information technology were introduced,followed by comments on how quantum supremacy threatens the current blockchain consensus and encryption mechanisms.Meanwhile,considering loopholes existing in the current blockchain technology,a blockchain system integrating quantum technology was discussed aiming to prevent the threat of quantum supremacy.

Key words: blockchain, cryptographic algorithms, quantum supremacy, quantum information technology, quantum blockchain
