Cryptocurrency has become a household topic, but a new report reveals it faces a potential threat that could affect anyone using digital currencies. Recent advancements in quantum computing may soon challenge the very encryption methods that keep cryptocurrency transactions secure.

The Quantum Threat to Crypto

According to a report released by Citigroup, advancements in quantum computing pose a significant long-term risk to the cryptocurrency market. As quantum technology continues to evolve, it is starting to threaten the encryption systems that protect crypto assets. Analyst Alex Saunders highlights that while large-scale quantum attacks are still viewed as a medium-term risk, the speed of these technological advances necessitates that investors pay close attention to the issue.

Quantum computers could specifically target public-key cryptography systems, such as those used by Bitcoin and Ethereum. This means that a sufficiently powerful quantum computer could hypothetically derive private keys from public keys. Such a scenario would allow adversaries to generate fraudulent transactions and steal assets from digital wallets.

Bitcoin’s Vulnerability

The report indicates that Bitcoin may be particularly exposed to these quantum threats. Its governance structure is more conservative, and updates to its protocols move at a slower pace than other cryptocurrencies. Wallets with publicly disclosed public keys, as well as older wallet types, are especially at risk. This includes wallets that are inactive or even those associated with Bitcoin’s creator, Satoshi Nakamoto. Citigroup estimates that between 6.5 and 6.9 million BTC, representing about one-third of the total Bitcoin supply, could be vulnerable with a current value of around $450 billion.

Further complicating matters, future quantum computers could potentially decrypt private keys even before Bitcoin transactions are finalized. Citigroup warns about an attack model known as “collect now, decrypt later,” where hackers could store encrypted data now to decrypt it later when quantum technology has sufficiently advanced.

Resilience of Newer Networks

Interestingly, the report mentions that proof-of-stake networks may have some level of resilience against quantum threats. These networks can implement protocol updates more frequently, potentially making them harder to compromise. However, Citi also noted that sufficiently advanced quantum computers could still interfere with validator keys and disrupt network functions.

Still, Citigroup believes that the cryptocurrency sector has the capacity to adapt to these risks in the long term. They advocate for the development of post-quantum cryptography solutions and new protocol designs as critical next steps. Specifically, upgrades like BIP-360 and BIP-361 for Bitcoin should be closely monitored for their ability to combat these new threats.
