Blockchain 
technologies
At the core of blockchain technologies, the 
most important aspects are consensus 
algorithms and digital signatures. Consensus 
algorithms can be used to generate blocks, 
while digital signatures can secure 
transaction information.

Quantum 
computation
Digital signatures are an essential application 
of public-key cryptography. In this case, the 
security of blockchain technology based on 
the digital signatures is under the threat of 
quantum computation.

How it works?
algorithms can be involved in blockchain 
technologies, which further improve system 
securities. A blockchain generated by the use 
of entanglement in time cannot trace back 
the transaction information, and thus the 
improvement in the overall security of the 
blockchain is poor.

Quantum blockchain 
algorithm
In the blockchain, the signer generates the 
transaction and then uses a private key to 
sign, and the receiver authenticates the 
transaction by using the signer’s public key to 
ensure transaction security in the aspect of 
cryptography.
