Quantum computing is advancing at a faster pace than many in the crypto industry anticipated, while preparedness across major blockchain networks continues to lag behind. A new study published by TechGaged.com, based on data from qLABS, highlights a widening gap between exposure to quantum risks and actual readiness across leading digital assets.
The research positions Bitcoin as the most vulnerable blockchain network, while Cardano emerges as the safest among the top Layer-1 ecosystems.
Quantum Vulnerability Index Reveals Top 10 Blockchain Risks
The findings are derived from the qLABS Quantum Vulnerability Index (qLVI), which evaluates the 10 largest Layer-1 blockchains based on exposure to quantum threats. The index considers key factors such as market value at risk, historical data exposure, and preparedness for quantum migration.
The ranking is as follows:
Bitcoin — 8.33
Hyperliquid — 7.90
BNB Chain — 7.87
Dogecoin — 7.77
Monero — 7.37
TRON — 6.83
Ethereum — 6.80
XRP Ledger — 6.30
Solana — 6.00
Cardano — 5.60
Bitcoin Tops Exposure Risk with No Clear Quantum Strategy
According to the study, Bitcoin ranks highest in quantum exposure, with approximately $1.5 trillion in theoretical value at risk and 17 years of publicly exposed blockchain data.
The report further notes that four of the top 10 networks currently lack any quantum migration roadmap, while two others acknowledge the risk without presenting actionable plans. This leaves a significant portion of the ecosystem underprepared for future quantum disruption.
Hyperliquid Identified as Least Prepared Network
While Bitcoin leads in overall exposure, Hyperliquid stands out as the least prepared blockchain in the index. The study highlights that it received the maximum Migration Unpreparedness score (MU = 10), reflecting a complete absence of roadmap, leadership acknowledgment, or strategic discussion regarding quantum threats.
Wider Industry Gap Between Risk and Readiness
The research emphasizes that the broader blockchain ecosystem continues to show a significant imbalance between exposure and preparedness. Networks such as BNB Chain, Dogecoin, and Monero are highlighted as lacking structured quantum readiness strategies, while TRON only acknowledges the risk without actionable implementation plans.
Cardano Leads Quantum Preparedness Rankings
In contrast, Cardano is identified as the most quantum-prepared blockchain, supported by long-term research initiatives and a clearly defined strategic roadmap.
Ethereum follows with active research programs and a structured migration timeline. XRP Ledger is also noted for its roadmap targeting full quantum readiness by 2028, while Solana has recently introduced a public plan that includes research development, wallet upgrades, and migration strategies.
Expert Insight on the Growing Readiness Gap
According to Jastra Kranjec, research PR analyst at TechGaged, the gap between quantum exposure and preparedness is expanding rapidly. She warns that without clearly defined migration strategies, even the largest blockchain networks could face systemic vulnerabilities once quantum computing reaches practical deployment levels.
Methodology Behind the Findings
The analysis is based on TechGaged research using data from the qLABS Quantum Vulnerability Index (April 2026). The index evaluates the 10 largest Layer-1 blockchains using a weighted model that combines market value at risk, historical data exposure, and preparedness levels. Scores range from 0 to 10, with higher values indicating greater vulnerability to quantum threats.
