Quantum won’t kill crypto—but it could accelerate Wall Street’s adoption of blockchain

Quantum computing may pose a threat to various sectors, but it is not a death sentence for the cryptocurrency industry. Despite the fears surrounding the possibility of quantum-powered attacks that could potentially expose trillions of dollars in assets and private data, the crypto industry appears to be better equipped to handle this challenge.

This is thanks to its open-source ethos and the ability to swiftly patch vulnerabilities and anticipate emerging threats. In contrast, legacy financial systems have historically shown delays in implementing critical upgrades, such as modernizing SWIFT's messaging format, which took seven years, or the Bank of England's ledger overhaul that took until 2025.

Given that the U.S. Government aims for critical infrastructure to be quantum secure by 2030, which is half the time it took for SWIFT's upgrade, the crypto industry's proactive approach to quantum readiness is particularly encouraging. Leading blockchain organizations have already published comprehensive plans for achieving post-quantum readiness before 2030, and Ethereum has set 2029 as its target date for quantum readiness.

Moreover, a wave of new startups in the crypto industry are developing novel post-quantum solutions, further solidifying the industry's position to meet the quantum challenge. As a result, the crypto industry might just leapfrog traditional players in the broader quest for quantum readiness. With increasing optimism, the author believes that blockchain technology, often considered vulnerable to quantum computing, could become a foundation on which the financial system rebuilds.
