Could you merge quantum cryptography and blockchain?

[8CommaClub]

If blockchain is a public ledger which stores all of the transactions that have occurred and will occur , would it better to merge both quantum cryptography and blockchain together to store immutable data instead of using something like a directed acyclic graph? (DAG)

A nice question. Im waitting for an answer too. I studied some projects using DAG to store data and transactions. But I just understood a little bit. And OP mention about Quantum cryptography. I also want to know what its specification. Thank you in advance.

merging between blockchain and quantum cryptography is really very good just now does anyone want to make that?
if there really is, I also strongly agree.

at this time there has never been a supercum supercharged blcockhain super computer. but from the arrays I read in 2019 Russian scientists will create the first quantum blochain and will spend a full year completing it

Moving this topic to Development and Tech Discussion will yield you better answers. Once when Quantum Computers emerges in future, it would be literally easy for them to break the public - private key combinations and change the cryptographic functions. Those futuristic devices can mine the blocks at a much faster rate than normal ASIC's and can even double spend the currencies. But merging of quantum cryptography with blockchain technology would be helpful to save the cryptocurrency future and to make the quantum machines impossible to break the code and to find the vulnerabilities.

There is a research paper published which is based on integrating Quantum Cryptography with blockchain. Though, quantum machines will be evolving only in future, it is safer to use the current cruptographic algorithms.

Can you please explain, what do you mean by quantum cryptography?

To answer your question, the algorithm that can do integer factorization on a quantum computer has not been successfully applied and quantum computing is very far from being available to regular people.
