Binance Founder CZ Says No Need to Panic, Bitcoin and Crypto Will Stay Post-Quantum

Concerns about quantum computing and its potential impact on crypto security have resurfaced following new research from Google. The discussion gained momentum after reports suggested that advances in quantum computing could enable attackers to break widely used cryptographic systems more quickly than previously expected.

In response, Binance founder Changpeng Zhao, commonly known as CZ, urged calm, stating that cryptocurrencies can adapt through upgrades to quantum-resistant algorithms. His comments come as the researchers suggest a possible post-quantum transition timeline as early as 2029. They had previously expected the shift to take place in the mid-2030s.

Google Quantum Breakthrough Sparks Crypto Security Concerns

Newly published findings by Google Researchers indicated a roughly 20-times more efficient implementation of Shor’s algorithm, a quantum computing method capable of breaking widely used cryptographic systems. According to the reports, a quantum computer with approximately 500,000 physical qubits could theoretically break Elliptic Curve Digital Signature Algorithm (ECDSA) keys within minutes.

ECDSA currently secures many major blockchains, including Bitcoin and Ethereum. The research has therefore triggered renewed discussion around the long-term security of digital assets.

CZ Says Crypto Can Upgrade to Quantum-Resistant Algorithms

Responding to the growing discussion, CZ emphasized that cryptocurrencies can adapt to advances in quantum computing. He stated that crypto networks can upgrade to quantum-resistant, or post-quantum, cryptographic algorithms, reducing the need for panic.

CZ acknowledged that implementation would not be straightforward in decentralized systems. Communities may debate which algorithms to adopt, potentially resulting in forks as different networks choose separate upgrade paths. New implementations could introduce bugs or short-term security risks, particularly during early adoption phases. Some inactive or abandoned projects may fail to upgrade altogether, but filtering out those dormant ecosystems would ultimately be a net positive.

CZ also noted that users holding assets in self-custody wallets would likely need to migrate funds to new quantum-resistant addresses. This process could create additional complexity, especially for long-term holders or inactive wallets.

Despite these challenges, he maintained that crypto will remain viable in a post-quantum environment. He emphasized that similar transitions have occurred in the past, including major protocol upgrades across leading blockchain networks.

Satoshi’s Bitcoin and Long-Term Security Questions

CZ also raised questions about dormant holdings, including the widely discussed wallets believed to belong to Satoshi Nakamoto. If advances in quantum computing reach practical levels, inactive wallets that do not migrate to quantum-resistant addresses could theoretically become vulnerable.

CZ suggested that if such coins remain unmoved for extended periods, it may be necessary to consider locking or effectively burning vulnerable addresses to prevent exploitation. However, he also acknowledged the difficulty of identifying all early wallets without affecting legitimate long-term holders.

Crypto Industry May Begin Post-Quantum Planning

Despite the concerns, CZ reiterated that encryption typically evolves alongside advances in computing. He emphasized that increased computing power also benefits defensive cryptography, allowing stronger encryption methods to emerge.

Post-quantum cryptography research is already underway across academia and industry, with developers exploring algorithms designed to resist quantum attacks. While practical quantum threats remain years away, the latest discussion highlights growing awareness and preparation within the crypto ecosystem.

As quantum computing development accelerates, industry participants will remain aware and monitor progress closely. For now, CZ urges patience, as cryptocurrencies can adapt and will remain resilient even in a post-quantum future.
