Reassurance on Bitcoin’s Security Amid Quantum Advancements
In the realm of cryptocurrency, Graham Cooke, a seasoned expert from Google, has provided reassurance regarding the security of Bitcoin in the face of advancing quantum computing technology. He asserted in a recent post on social media that the mathematical principles underpinning Bitcoin wallets are exceedingly robust, even surpassing the complexities of spacetime itself.
Concerns Over Quantum Computing Developments
This statement comes amidst heightened anxiety within the crypto community triggered by Microsoft’s introduction of the Majorana 1 quantum chip, which has the potential to escalate to an impressive one million qubits. This chip utilizes a groundbreaking material known as a ‘topoconductor’, conceived by Microsoft’s engineers. The advancement raises concerns among Bitcoin enthusiasts, who fear that a computer with such capabilities could crack the encryption protecting Bitcoin addresses.
Stability of Quantum Qubits
Cooke elaborated on the stability of Microsoft’s qubits compared to traditional ones, using an analogy of a knot in a rubber band that can endure alterations yet retain its form. He emphasized that this unique stability would allow quantum computers to evolve towards millions of qubits without losing their quantum properties.
Advancements from Other Tech Giants
Alongside the developments from Microsoft, other key advancements in quantum computing from firms like Google and IBM are igniting discussions about the endurance of Bitcoin’s cryptographic defenses. As the current CEO of Brava Labs, a blockchain startup, Cooke firmly believes that skeptics of Bitcoin’s security fundamentally overlook the extraordinary power of mathematics that protects digital currencies.
Strength of Bitcoin’s Cryptographic Algorithms
Despite the brisk progress of quantum technologies, Cooke reassured stakeholders that the algorithms safeguarding their crypto wallets hold more strength than the average person comprehends. For instance, he pointed out the extraordinary number of possible keys derived from a Bitcoin seed phrase, positing that a 24-word seed phrase yields 340 septillion trillion more combinations than its 12-word counterpart.
To illustrate the almost insurmountable task of hacking it, Cooke mentioned a hypothetical scenario involving 8 billion people, each equipped with a billion supercomputers, attempting a billion combinations each second. The timeframe to successfully decipher a seed phrase in this manner would exceed 1040 years – a figure that dwarfs the universe’s age of approximately 14 billion years.
As Cooke famously noted, “one would need to reset the universe trillions of times to even be close to achieving this feat.”
