Binance Blog published a new article, revealing insights into how quantum computing could affect the long-term security of blockchain networks and what the crypto industry is doing to prepare. The article says quantum computers cannot break today’s major blockchains, but recent research has renewed attention on the need to adopt post-quantum cryptography early. It explains that the cryptography required to defend against future quantum attacks already exists, while the main challenge is getting the wider crypto ecosystem to upgrade in a coordinated way. Binance says preparation before threats become urgent is central to building long-term security, and the piece outlines what has changed, why the topic is drawing more attention, and what crypto users can do in the meantime. The article stresses that today’s systems are not immediately vulnerable, but that upgrading blockchains, wallets, exchanges, and custodians will take years, which makes early planning important.

Quantum computing is described as a long-term issue rather than an immediate threat. The article explains that conventional computers use 0s and 1s, while quantum computers use quantum physics to solve certain problems more efficiently. Major blockchains rely on public-key cryptography to protect wallets, transactions, and digital assets, and current quantum machines are still too small and error-prone to break those defenses. However, a Google Quantum AI paper published in March 2026 suggested the computing power needed to break the public-key cryptography used by blockchain networks may be around 20 times lower than earlier estimates, due to more efficient quantum algorithms rather than a sudden improvement in hardware. The article says these findings highlight the importance of preparing now. It advises users to keep crypto apps updated, use new receiving addresses when self-custody wallets recommend them, follow security guidance from wallet or exchange providers, and stay informed through trusted sources. Binance also notes that in 2024, the U.S. National Institute of Standards and Technology finalized its first post-quantum cryptography standards, giving governments and companies a foundation for future upgrades.
