Bitcoin's Security Vulnerability to Quantum Computing Highlighted by Galaxy's Alex Thorn
Sounding the Alarm: Quantum Computing's Imminent Threat to Bitcoin
Alex Thorn, Galaxy Digital's Head of Research, has raised a red flag over a perilous threat lurking in the shadows—quantum computing. He warns that the peril is greater than many realize.
Thorn stresses that while a quantum attack would impact all public key cryptography and consequently all cryptocurrencies, the solutions to protect Bitcoin aren't the best, at present.
Quantum Threat Multiplying BTC's Woes
For starters, quantum computing endangers Bitcoin by potentially rending its cryptographic security ineffective. This includes elliptic curve cryptography (ECC) and hash functions like SHA-256. Quantum computers could derive private keys from public ones, thus enabling unauthorized access.
Meanwhile, quantum-resistant cryptography is under development, yet the timeline for a fully secure solution remains ambiguous. Some remain skeptical about the effectiveness of solutions to protect Bitcoin.
"Quantum is a bigger headache than people imagine, and the options to fix it for Bitcoin are worse than people think," Thorn posted.
When probed about a possible timeline for the emergence of this threat, Thorn admitted that no one knows for sure, making it one of the most challenging questions in the field.
"This is a 'national security' level question," Thorn asserted.
Thorn suggests that by the time the threat materializes, it may already be too late to respond. His recent concerns reverberate among many.
Nate Geraci, President of the ETF Store, reaffirms his earlier stance. He notes that, like any technology, Bitcoin has the potential for vulnerabilities that could surface with time.
"There's a non-zero chance Bitcoin could be compromised. If it can be manufactured, it can be toppled," Geraci added.
Some even foresee a bleak future for Bitcoin due to quantum computing.
"Right time to invest in Bitcoin was before 2020. I'm aggressively researching the next Bitcoin-like asset," analyst Nishant Bhardwaj remarked.
The concerns have escalated with recent advancements in quantum technology, triggered by Google's quantum computers now operating 241 million times faster than conventional computers.
"A quantum computer with just 4,000 qubits could crack Bitcoin's encryption in 10 minutes. By 2030, they'll crack Bitcoin's encryption in seconds," Chirag Jetani, Founder and COO at Diamante, said.
Quantum: The Double-Edged Sword
Despite the risks quantum computing poses, it offers immense potential. Jetani outlines five ways it will revolutionize blockchain by 2030.
- Quantum-Resistant Cryptography: This involves creating encryption that is secure against quantum computers. The US National Institute of Standards and Technology (NIST) is at the forefront of this endeavor.
- Quantum-Enhanced Smart Contracts: Quantum computing could foster smarter, real-time adapting contracts for faster, autonomous decisions.
- Quantum Random Number Generation: Blockchain could leverage quantum randomness for secure voting, fair gambling, and tamper-proof processes.
- Quantum-Secure Identity Systems: Quantum computing could ensure unhackable digital identities, protecting personal data and privacy.
- Quantum-Powered DeFi: Quantum computing could transform DeFi with instant payments, advanced financial modeling, and real-time risk assessment.
"You need to start transferring your assets to quantum-resistant systems now. Because by 2030, it'll be too late," Jetani cautions.
Will Bitcoin Outlast Quantum Computing?
Despite the warnings, some remain optimistic. Tether's CEO, Paolo Ardoino, predicts that quantum computing isn't likely to pose a meaningful threat to Bitcoin's cryptography anytime soon. He believes that quantum-resistant addresses will be added to Bitcoin in time, before any serious risk arises.
Quantum computing research firm, Project 11, also stresses that quantum computers posing an actual threat to proof of work isn't expected for at least 10 years. The firm believes that Bitcoin, despite its vulnerability to future quantum computing advances, could survive through technological upgrades and adaptations.
Time will tell whether Bitcoin can evolve swiftly in response to quantum advancements while preserving its decentralized ethos.
