A new Security model for blockchain Using Quantum Computing

Abstract

Quantum computing is the solution to many
complex problems that technology facing today, like a
replica of quantum computing systems and large number
factorization. The concept of the quantum computing
mechanism is pretty well accepted. Quantum computing is
both boon and bane to our current blockchain technology
which is fully established on encryption mechanism and
hashing functions. Digital signatures in a blockchain may
allow an attacker to fetch the identical key. Determining
hash may be easy. So, ongoing blockchains also need their
own resettling. We can achieve this by developing a new
protocol or creating a post-quantum mechanism. Creating
a quantum-based blockchain is a solution to this.
Generating quantum-based replica of each block and
maintaining that block in a superposition that can’t be
altered with normal computers. To alter a quantum-based
block with the same quantum computing technology is also
impossible or it takes more than 2000 years because to
achieve this we need more than 50 qubit quantum
computers, which is not created yet. The IBM-created
quantum computer comes with only 27 qubit falcon
processor.
