Shor’s Algorithm

Shor's algorithm is a quantum algorithm that can factor large integers and solve discrete logarithm problems in polynomial time. This means it could theoretically break the public-key encryption that currently secures most of the internet and the blockchain ecosystem.

If a powerful enough quantum computer were built, it could derive private keys from public keys, effectively compromising any wallet or contract. The threat posed by this algorithm is the primary driver behind the development of quantum-resistant cryptography.

It serves as a benchmark for how powerful quantum computers need to be before they become a genuine threat to existing assets. Understanding the implications of this algorithm is essential for developers working on the next generation of financial infrastructure.

It is the ultimate wake-up call for current cryptographic standards.
