The rapid advancement of quantum computing technology is posing an unprecedented challenge to the foundational security of cryptocurrencies. Analysts suggest that warnings from crypto entrepreneur Nic Carter directed at Bitcoin developers are not alarmist. If Bitcoin fails to accelerate its research into quantum resistance and keep pace with Ethereum, its long-term security premium as "digital gold" could be eroded. The Elliptic Curve Cryptography (ECC) that underpins the Bitcoin system is showing its limitations. Developers face the dual challenge of maintaining decentralization while integrating a more resilient cryptographic architecture into the existing network. Regarding the distribution of risks from technological evolution, analysis indicates that approximately one-third of all Bitcoin globally is potentially vulnerable to quantum computing attacks. While this threat is not immediately critical in the short term, the failure of current encryption standards becomes highly probable within the next 3 to 10 years, a period expected to see significant technological breakthroughs. Data shows that Ethereum has taken a proactive stance by establishing a dedicated security team and targeting 2029 as the strategic deadline for its post-quantum migration. This forward-looking approach to future risks demonstrates a distinct advantage in system robustness. Proposals for upgrading signature and storage systems put forward by Vitalik Buterin are positioning Ethereum to gain a competitive edge in the post-quantum era. Despite internal divisions within the Bitcoin community over whether to break from its "hard-coded" traditions, the wave of technological innovation is unavoidable. Nic Carter has criticized core developers for being passive regarding quantum-related proposals like BIP-360. Although proponents of these proposals emphasize that community engagement has reached record levels, it remains uncertain if this pace of feedback can outstrip the growth of quantum computing power. Concurrently, tech giant Google has set a clear post-quantum migration deadline of 2029, serving as a wake-up call for the entire digital asset industry and signaling that the security of current digital signature standards is on a ticking clock. In this cryptographic race关乎生存的密码学竞赛中, the flexibility of blockchain systems will ultimately determine their viability. Analysts believe that rigid adherence to early architectural designs may not withstand the computational power of the quantum era. Bitcoin must find a new equilibrium between core consensus and technological iteration. By actively incorporating community feedback and advancing comprehensive architectural upgrades, Bitcoin can continue to defend the security margin of decentralized assets in the post-quantum era, especially as major technology firms increasingly enter the space.
