Currently, the 暗号 industry is already struggling amidst public opinion controversies, geopolitical conflicts, and financial turmoil. Google’s latest research has brought a new challenge to this field: the timeline for the practical implementation of quantum computing is being continuously accelerated.

For years, the potential threat posed by quantum computing has been discussed, debated, and researched within the industry. Blockchain developers have long been working on quantum-resistant encryption technologies. However, what truly stirs the investment market is the pace of technological iteration. Google’s Quantum AI team pointed out that a quantum computer would need less than 500,000 qubits to crack the elliptic curve cryptography used by Bitcoin—an encryption method long considered the most secure. Setting aside the technical parameters of qubits, the key fact is: the latest estimates for the required number of qubits are far lower than previously expected, which also advances the potential “life-or-death test” for the blockchain ecosystem to around 2029.

Besides the possibility of Bitcoin exposing security vulnerabilities in as little as 9 minutes, another report highlighted the risks faced by Ethereum: the network has up to 5 potential attack vectors. If exploited, these could endanger approximately $100 billion worth of DeFi and tokenized assets.

It is important to clarify that the quantum computers mentioned in these research reports have not yet truly materialized and remain theoretical. However, the related discussions have already driven tokens and protocols with quantum-resistant features to achieve double-digit gains. Furthermore, tokens considered “quantum-adapted,” which utilize more advanced protocols like zero-knowledge proofs, have also benefited from this wave of attention.

Setting aside speculative sentiment and panic-driven surges, as quantum technology continues to permeate the broader financial markets, investors should recognize some key lessons and insights.

Quantum Risk Is No Longer Theoretical, and That’s Actually a Good Thing

The discussion around quantum computing and cryptocurrency has shifted from abstract risks to quantifiable, practical threats.

New research suggests quantum systems might need only 10,000 to 26,000 qubits to break currently widely-used encryption standards, a significant reduction from previous estimates in the millions. More importantly, the attack scenarios are no longer hypothetical. Researchers have outlined specific attack methods: extracting private keys from ongoing transactions within minutes, or even transferring funds before a transaction is confirmed.

This reality reデフィnes the core issue for investors, auditors, and policymakers: the risk is no longer just “will quantum computers emerge,” but whether existing systems can migrate to post-quantum cryptography fast enough. Some estimates suggest the “quantum node” could arrive as early as 2029, leaving a response window shorter than the upgrade cycles of most financial infrastructures.

From a practical perspective, the market faces a classic accounting and valuation challenge: the need to recognize and assess contingent liabilities before they materialize into actual losses.

について 市場 Is Already Pricing in the Quantum Transition

Despite the underlying threat still unfolding, market behavior shows participants are not waiting for clarity. トークンs and projects touting quantum-resistant features have seen gains approaching 50%, indicating capital is positioning early in defensive infrastructure and related projects.

This is a common pattern in financial markets: investors often price in structural risks before they fully materialize. In the current context, this means capital will flow towards quantum-resistant cryptography, upgraded blockchain protocols, and security-focused players in this space.

Meanwhile, despite increasingly clear warnings, the prices of mainstream crypto assets remain relatively stable. This reflects a growing market consensus: this transformation will be accomplished through protocol-level upgrades, not the demise of the industry.

For accounting and auditing professionals, this introduces a new dimension to valuation analysis. Digital assets must now contend not only with market volatility and regulatory changes but also with technological obsolescence risk—a risk that must be disclosed, modeled, and stress-tested.

The Crypto Industry Is Unlikely to Perish, But Its Underlying Architecture Will Be Reconstructed

Despite increasingly urgent warnings, the overall conclusion from various research and industry commentary is clear: quantum computing will not destroy blockchain but will force a reconstruction of its security architecture. Recent analyses point to multiple attack vectors, ranging from fast exploits targeting transaction-level vulnerabilities to slower attacks targeting dormant wallets with exposed keys.

Concurrently, ongoing research in the post-quantum cryptography field shows that viable solutions already exist, though their adoption remains uneven.

Importantly, any observer, investor, or policy advocate can attest: blockchain systems are not static. Protocol upgrades, hard forks, and cryptographic algorithm migrations are already part of the ecosystem’s operational mechanics. Compared to traditional financial infrastructure, this adaptability is itself a structural advantage.

Quantum computing presents not a fatal flaw, but a forced opportunity for progress. The ultimate winners will not be those trying to avoid the risk, but those driving the transformation forward, embedding quantum resistance into governance, disclosure, and technical design before the threat fully materializes.

Looking back over the past five years, from stablecoins to U.S. Treasuries, and then to funds and U.S. stocks, mainstream assets have been gradually introduced into the on-chain system. Through tokenization, they have become new, tradable financial products, to some extent validating the on-chain trading logic for secondary market assets from traditional finance (TradFi). However, the primary market—the realm hiding super unicorns like SpaceX, ByteDance, OpenAI, and Anthropic—remains tightly shut. Users can trade Tesla stock seamlessly on-chain, yet it remains difficult to secure a “ticket” to SpaceX before its IPO. Nevertheless, since last year, boundaries have indeed been tested: Robinhood experimented with tokenized private equity products like OpenAI in Europe, Hyperliquid listed perpetual contracts for assets like SpaceX, and this week, MSX launched on-chain Pre-IPO share offerings for unicorns including…
