$2,5trn in crypto exposed to quantum attacks

More than $2.5 trillion in cryptocurrency value across the top 20 blockchains remains vulnerable to quantum attacks, as none are fully quantum-protected, according to data from TechGaged and qLABS Research. While quantum-resistant technology exists, major blockchains like Bitcoin, BNB Chain, and Dogecoin lack clear upgrade plans, with Bitcoin alone exposing $1.6 trillion—71% of the top-20 L1 capital—without a formal migration strategy. Eight blockchains, including Ethereum, XRP, Solana, and Cardano, are actively developing quantum-resistant security, but their combined market cap of $456.5 billion represents only about one-fifth of the total crypto market. Another seven chains, such as BNB Chain and Hyperliquid, have no quantum security plans at all, while five others acknowledge the risk without a clear path forward. The exposure varies sharply: $1.67 trillion sits on chains that recognize the threat but lack solutions, $122.7 billion on those with no public plans, and just $456.5 billion on chains actively preparing. BNB Chain stands out as the largest network with no quantum security measures, leaving $87.3 billion exposed, while Hyperliquid, valued at $10.3 billion, shows no visible preparation. Cardano leads in quantum readiness with a long-term strategy, followed by Ethereum and XRP, which aims for full quantum readiness by 2028. Solana introduced a public quantum-readiness roadmap last month, but none of these networks are yet fully secure. The data highlights a growing gap between blockchains treating quantum risks as urgent and those dismissing the threat as distant. Experts warn that quantum computing is advancing faster than the crypto industry’s ability to adapt. Jastra Kranjec of TechGaged emphasized that quantum risk is no longer theoretical, as quantum advancements outpace crypto’s security upgrades. The analysis underscores the urgent need for broader adoption of quantum-resistant solutions across the industry.
