a16z: Quantum threat to crypto is exaggerated, focus on current vulnerabilities

The threat of quantum computing to cryptocurrencies is exaggerated, and the industry should prioritize solving more immediate problems like security vulnerabilities, according to Andreessen Horowitz (a16z) Crypto. In a post on X, the firm explained that a quantum computer capable of breaking current cryptosystems within a month using Shor's algorithm does not yet exist, based on public technological forecasts. a16z argued that major public chains like Bitcoin and Ethereum face more pressing issues, including difficult protocol upgrades, complex governance, and security flaws. While the quantum threat is a long-term challenge, the firm stated that fixing practical vulnerabilities such as bugs and side-channel attacks should be the immediate priority.
