Quantum Threat Resurfaces for Bitcoin, QRL Surges 40%
New research highlights critical quantum computing risks to Bitcoin's cryptography, potentially impacting 25-30% of its supply. Meanwhile, quantum-resistant token QRL rallies 40%.
Quantum Computing Threat Looms Over Bitcoin
New research has intensified concerns over quantum computing's potential to compromise Bitcoin's foundational cryptography. Reports published on March 31, 2026, indicate that breaking the Bitcoin blockchain's security could require fewer than 500,000 qubits, a significant reduction from prior estimates.
A separate study by Caltech and Oratomic suggests a system with approximately 26,000 qubits might breach the encryption standard securing both Bitcoin and Ethereum within about 10 days. This vulnerability, affecting an estimated 25-30% of the total Bitcoin supply, challenges the core tenets of crypto, including "trust the code."
Dragonfly Managing Partner Haseeb warns that while these attacks remain theoretical, they necessitate an upgrade to quantum-safe technology for the network by around 2029. Following these revelations, Bitcoin (BTC) saw a pullback to $66,250 from over $68,000, amidst broader market weakness and rising real bond returns.
The Quantum Hedge: QRL Sees Significant Gain
Amidst Bitcoin's decline and macro uncertainties, one token, QRL (Quantum Resistant Ledger), experienced a notable surge. The native cryptocurrency of the Quantum Resistant Ledger jumped 40% in 24 hours, reaching a high of $1.62 and pushing its market capitalization beyond $127 million.
QRL positions itself as an "externally audited enterprise-grade blockchain platform" designed to withstand future quantum computing advancements. Unlike Bitcoin, which relies on vulnerable elliptic curve cryptography, QRL employs the NIST-recognized XMSS (eXtended Merkle Signature Scheme) for quantum-safe, one-time signatures.
Seizing Market Volatility
The re-emergence of quantum risk, coupled with QRL's strong performance, underscores the dynamic nature of the crypto market. Traders are closely monitoring how these technological shifts and market reactions could present new opportunities in both established and emerging assets.
