The Wall Street Journal (WSJ) has issued warnings regarding a prospective threat to Bitcoin (BTC) from quantum computing, labeling it in a recent article as “a time bomb waiting to explode.”
The article discusses the possibility that advancements in quantum computing could jeopardize Bitcoin’s security, posing a potential threat to the entire blockchain sector.
Theoretically, a quantum computer could break private keys within minutes, which would undermine the current security framework of Bitcoin. This discussion was recently reignited following Google’s unveiling of its Willow quantum computing chip on December 9.
Concerns emerged within the crypto community about the potential for a quantum hack to occur sooner than the widely accepted timeline of 10 years. As a result, the WSJ article examined the likelihood of such an event and its implications for the traditional financial system.
$3 Trillion Impact
The article referenced projections from a 2022 study by the Hudson Institute, which estimated losses could exceed $3 trillion across both crypto and traditional financial markets, possibly sparking a global recession.
Arthur Herman, a senior fellow at the Hudson Institute, remarked:
“This is a time bomb that could explode if someone develops quantum-computer hacking and uses it against cryptocurrencies.”
Furthermore, the WSJ noted that Bitcoin’s market capitalization reached $2.1 trillion at its all-time high of $108,000, suggesting that these estimates have likely increased.
Skip Sanzeri, co-founder of the quantum-safe cybersecurity firm QuSecure, shared insights with the WSJ:
“Bitcoin will be a major target. Unlike banks that have regulations and protective measures, Bitcoin operates in a lawless environment. If your Bitcoin is stolen, there’s no one to reimburse you.”
Additionally, the article highlighted that 1.72 million BTC is currently dormant in wallets with exposed public keys, making them particularly susceptible to quantum hacking, including wallets belonging to Bitcoin’s pseudonymous creator, Satoshi Nakamoto.
Moreover, it noted that even Bitcoin transactions awaiting confirmation in the 10-minute block time are at risk, as hackers could potentially break the encryption and reroute funds.
Not Waiting for the Apocalypse
Despite the perceived threat, experts assert that there is still time to take preventive measures. Emin Gün Sirer, founder of Avalanche, maintains that the immediate anxieties are overstated. He stated:
“There is certainly a quantum apocalypse looming on the horizon, but it is far enough away that there is no reason to panic.”
In August, tech giant Meta discussed the potential for a “quantum apocalypse” in an episode of its Metatech Podcast, where engineers indicated that a breakthrough in quantum technology could impact blockchain and all sectors reliant on encryption.
Consequently, software engineers are actively working to establish robust post-quantum cryptography. In Meta’s approach, they are integrating traditional algorithms with innovative technologies to develop security standards that are effective both currently and in the future.
This indicates that while quantum computing represents a genuine risk to the blockchain sector, labeling Bitcoin as a ticking time bomb overlooks the ongoing efforts to safeguard the integrity of the crypto ecosystem.
Meta’s technical team concluded their discussion optimistically, acknowledging that although creating quantum-resistant cryptography is a complex challenge, it is one that can be approached with determination.
