Research Report | Analysis Report on Quantum Mechanics and Blockchain Security Technology

Author: gate.io Institute

Quantum mechanics is becoming more and more important for the scientific development of today's society. With the promotion of quantum mechanics theory and its derivative applications, all walks of life are quietly changing. Blockchain, as one of the disruptive technologies of this era, its security must face the test brought by quantum algorithms. For the possible quantum attacks in the future, this article will guide the readers to start from the basic concepts of quantum mechanics, and jointly discuss the challenges and countermeasures of blockchain technology. Finally, the article will take Bitcoin as an example to analyze the threat that quantum algorithms pose to its system.

Summary of the main points of this article

-At the end of the 19th century, scientists discovered that it was impossible to interpret all phenomena using classical mechanics, and then began to study and discuss quantum mechanics and reached some conclusions, and proved the equivalence of Schrodinger's "wave dynamics" and Heisenberg "matrix mechanics" .

-Quantum mechanics is widely used in modern scientific research, and the "quantum key distribution technology" developed using the polarization and uncertainty of particles is one of the most advanced encryption technologies.

-With the improvement of modern scientific research level, traditional computers have been unable to meet the needs of the simulation of the microcosm. Quantum computers based on quantum mechanics theory have gradually become the research target of major technology giants.

-The advent of quantum computers and quantum algorithms poses a serious threat to blockchain encryption mechanisms. Hash algorithms and key encryption algorithms may be cracked. Among them, "Grover algorithm" and "Shor algorithm" are extremely efficient for breaking the elliptic curve algorithm and SHA256 algorithm.

-At present, anti-quantum algorithm is a feasible method to counter the attack of quantum algorithm, but there is still a risk of node centralization.
