Most of the dominant blockchains are not immune to quantum dangers, meaning that the technology that secures your crypto today could be compromised tomorrow.

According to TechGaged.com, six of the top 10 blockchains are unprepared for quantum intrusions; Bitcoin is recognized as the most at risk, followed by Hyperliquid and BNB Chain. Here’s a breakdown of the rest of the market.

The quantum threat is growing and the crypto market is divided, according to the qLABS Quantum Vulnerability Index (qLVI), which ranks the top 10 Tier 1 blockchains by their exposure to quantum risks, including market value at risk, exposure to historical data and level of readiness. The index uses a weighted model that combines these factors to assess real vulnerability.

The results reveal a marked split in the cryptosphere, separating those blockchains that perceive quantum attacks as a real threat from those for which it is still only a distant scenario.

According to the index, four out of ten blockchains have no plan of action against quantum attacks at all, and another two recognize the risk, but without a clear maneuver. Bitcoin is the most vulnerable.

Bitcoin leads the way with an estimated risk of about $1.5 trillion, 17 years of open data on the network and no clear path to quantum security, making the highest-value network the most difficult to modernize.

It is followed by Hyperliquid, the only major system that has taken absolutely no steps to prepare for quantum technologies, including no clear plan, public acknowledgement or broad discussion of quantum risks. BNB Chain ranks third on this list due to its large ecosystem and lack of a specific quantum readiness plan, which makes it a high risk.

However, most of the other significant blockchains also do not demonstrate explicit readiness. Networks such as Dogecoin and Monero lack clear strategies, while TRON is aware of the risk but has no defined steps, placing it in the middle of the ranking.

The qLABS Index also showed that while all major blockchains rely on cryptography that could eventually be hacked by quantum machines, only four are actively preparing for this risk and working to minimize it.

Cardano is the network with the highest preparedness for quantum threats, relying on years of research and a clearly outlined long-term strategy. Ethereum follows with a clear roadmap and active research. XRP Ledger is also among the leaders, aiming for full quantum readiness by 2028, and Solana recently unveiled a public plan outlining research, new wallet deployments and transitions.

This is critical because networks that prepare in advance are much less at risk if quantum threats manifest themselves sooner than expected, while others may be forced to make hasty and risky upgrades.

Recent revelations confirm this shift: peer reviews have dropped significantly, meaning the time it takes to crack modern cryptography is shorter; companies such as Google and Cloudflare have already mapped out 2029 for a full migration to post-quantum technologies.
