If macro worries tied to the Iran conflict weren’t enough, new research has revived what might be seen as an existential threat to bitcoin BTC$66,436.28, quantum computing.

A paper from Google suggests breaking the Bitcoin blockchain's cryptography with quantum computers could require fewer than 500,000 qubits, a fraction of previous estimates. A separate paper by Caltech and quantum startup Oratomic suggests a system with around 26,000 qubits could break the encryption standard that secures the Bitcoin and Ethereum blockchains, in about 10 days. (“Qubits” are considered the processing power units of quantum computers.)

A quantum hack would compromise the core tenets of crypto, namely "trust the code" and the "hard money" value proposition, according to Charles Edwards, founder of Capriole Investments. About 25%-30% of the total bitcoin supply is already vulnerable to future quantum computing attacks.

While these attacks remain theoretical, according to Dragonfly Managing Partner Haseeb, they put a deadline in place: The network may need to upgrade to quantum-safe technology by around 2029.

The leading cryptocurrency by market value has already pulled back to $66,250 from the high of over $68,000 reached during Asian trading hours. This comes as demand-side conditions appear weak and real or inflation-adjusted returns on bonds rise, disincentivizing investment in risky and emerging technologies such as bitcoin.

While the broader market followed bitcoin lower, one token stood out. QRL, the native cryptocurrency of the Quantum Resistant Ledger, has surged 40% in 24 hours, hitting a high of $1.62. The token's market cap was just over $127 million at the time of writing.

QRL describes itself as "an externally audited enterprise-grade blockchain platform secure today from the quantum computing advances of tomorrow."

Unlike Bitcoin, which relies on elliptic curve cryptography that makes it vulnerable to quantum attacks, QRL uses a quantum-safe signature scheme called XMSS (eXtended Merkle Signature Scheme).

XMSS is a post-quantum cryptography algorithm recognized by standards bodies such as NIST for its resistance to quantum attacks. By design, XMSS generates one-time signatures that are extremely hard for quantum computers to crack, making QRL theoretically “future-proof” against quantum threats.

The takeaway: Projects like QRL could draw more attention and potentially gain market value as concerns about quantum threats grow. Stay alert!
