As quantum computing advances toward 'Q-Day', the cryptographic infrastructure underpinning crypto assets faces imminent disruption. This article examines the necessity of coordinating regulatory frameworks with post-quantum cryptography (PQC) migration, emphasizing that institutions must embed quantum resilience into financial infrastructure security, while investors should assess projects' dual readiness in regulatory compliance and cryptographic adaptability.
As quantum computing approaches 'Q-Day', crypto assets face the risk of a complete overthrow of their cryptographic infrastructure. Once quantum computers achieve the capability to break current public-key encryption standards (such as RSA and ECDSA), the private key protection and transaction signature mechanisms of major crypto assets like Bitcoin and Ethereum will become invalid, fundamentally undermining asset security and on-chain trust models.
From a regulatory perspective, policymakers must proactively advance the standardization and migration roadmap for post-quantum cryptography (PQC), collaborating with the crypto industry to build a quantum-resilient framework. Institutional investors should incorporate quantum risk into their financial infrastructure security assessments, prioritizing projects' dual preparedness in both regulatory compliance and cryptographic adaptability to avoid the systemic shocks that 'Q-Day' could bring.
