Bitcoin faces quantum risks by 2030 – Can developers secure BTC in time?

Conventional asymmetric (public-key) cryptography may become unsafe as early as 2030 due to advances in quantum computing, according to estimates from research and advisory firm Gartner. This was just one among half a dozen other concerns the firm outlined early in 2026. The list of threats included agentic AI creating new attack surfaces and introducing challenges for traditional identity and access management (IAM). It also highlighted regulatory volatility, which is making cybersecurity an increasingly critical business risk, among other concerns.
