In August 2025, Ethereum co-founder Vitalik Buterin warned that there was a 20% chance that quantum computers would crack cryptography by 2030, four years from now. Although some forecasts predict that “Q-Day” will happen around 2040, the clock is ticking, and there has been significant progress in quantum computing. Q-Day is the hypothetical moment when a quantum computer becomes powerful enough to shatter the cryptographic foundations of the modern world. For PIVX, a cryptocurrency built on the pillars of security and privacy, this raises a critical question: Is PIVX quantum-resistant or ready for the quantum age?The Quantum Threat: Shor’s and Grover’s AlgorithmsTo understand PIVX’s position, we must look at the two primary quantum “weapons” that threaten cryptocurrencies
