Although quantum computing is still in its infancy, it could pose a threat to Bitcoin and other proof-of-work algorithms in the near future, according to Amit Mehra, a partner at venture capital firm Borderless Capital. Speaking at the Global Blockchain Congress Dubai 2025, Mehra shared that the firm is deeply exploring quantum computing and the development of quantum-resistant technologies. He anticipates that quantum computing will mature by the end of the decade but warns that the rapid pace of advancements in chip and decentralized computing technology could accelerate its impact. Quantum computing leverages the principles of quantum physics to process information at unprecedented speeds and has the potential to break the cryptographic protections underpinning cryptocurrencies, driving the urgent need for post-quantum security standards.
Charles Edwards, founder of the Bitcoin and digital asset fund Carpriole, stresses the urgency of addressing quantum threats immediately, warning that failure to do so could cause Bitcoin to lose its competitive edge to gold permanently.
Efforts to prepare for quantum threats are underway across the blockchain ecosystem. For example, SUI Research has developed a new cryptographic framework to shield blockchains like SUI, Near, Solana, and Cosmos from quantum attacks without requiring disruptive hard forks or key resets. However, similar robust solutions for Bitcoin and Ethereum remain elusive.
At a governmental level, the US is evaluating investments in quantum computing to maintain national security and technological leadership, with the Department of Commerce reportedly considering funding initiatives to compete with China in this emerging field.
