  We proposed a framework of quantum-enhanced logic-based blockchain, which
improves the efficiency and power of quantum-secured blockchain. The efficiency
is improved by using a new quantum honest-success Byzantine agreement protocol
to replace the classical Byzantine agreement protocol, while the power is
improved by incorporating quantum protection and quantum certificate into the
syntax of transactions. Our quantum-secured logic-based blockchain can already
be implemented by the current technology. The cryptocurrency created and
transferred in our blockchain is called qulogicoin. Incorporating quantum
protection and quantum certificates into blockchain makes it possible to use
blockchain to overcome the limitations of some quantum cryptographic protocols.
As an illustration, we show that a significant shortcoming of cheat-sensitive
quantum bit commitment protocols can be overcome with the help of our
blockchain and qulogicoin.
