#夏日创作营 Quantum computing shock is coming—could Bitcoin’s dominance be shaken? Cardano founder Charles Hoskinson offers key insights

The crypto market’s landscape has never been static. Recently, Cardano (ADA) founder Charles Hoskinson made public remarks, delivering a highly thought-provoking judgment about Bitcoin’s future development, which has sparked wide discussion across the entire crypto community.
In his view, the security risks brought by the maturation of quantum computing technology will become a major test for Bitcoin’s governance system. Quantum computers have far greater computing power than conventional devices; once deployed, the existing Bitcoin encryption mechanisms would face decryption risks directly. At that time, the network would need to complete large-scale upgrades at the underlying layer to withstand this technical crisis. But Bitcoin’s biggest shortcoming is precisely that it is extremely difficult to upgrade and adjust.
Hoskinson described BTC’s current state as “frozen in time.” The community consensus is fragmented, and every protocol change requires coordination among multiple parties—miners, token holders, and the development team—resulting in very low progress efficiency. If, when facing quantum threats, the entire network cannot quickly reach a unified upgrade plan, Bitcoin could very possibly lose its throne as the world’s top cryptocurrency.
These comments are not empty venting—there is industry history behind them from the early days of public-chain development. The founder noted that in the early years, many participants disliked Bitcoin’s rigid nature and lack of flexibility for iteration, so they chose to start anew. Ethereum’s emergence was directly tied to this industry disappointment. Newer public chains like Ethereum and Cardano reserved governance mechanisms for rapid iteration from the underlying design stage, leaving them with more room to adjust when facing new technical risks.

After the news went out, discussions in the crypto world have already split into two camps. Bitcoin supporters believe the community had already laid out anti-quantum solutions in advance; the long-term consensus is solid enough that it won’t be easily replaced. Meanwhile, altcoin investors seized on this viewpoint, betting on flexible public chains and expecting market upside dividends.
From an objective perspective, Hoskinson’s remarks essentially point to the core competitive logic of the public-chain track: besides price and market value, the network’s ability to self-reform is what truly determines long-term survival. The security challenges of the quantum era are just a microcosm; in the future, all kinds of new technologies and new demands will continuously test the governance efficiency of every public chain. For ordinary crypto participants, this signal is worth noting: the market valuation logic is quietly shifting. Relying solely on the historical halo of established coins is no longer an absolutely safe choice. Public chains that have efficient iteration and robust anti-risk mechanisms are more likely to gain long-term favor from capital. Of course, large-scale commercialization of quantum computing still has a long cycle, and the Bitcoin community has also been developing corresponding protection measures. In the short term, the landscape won’t be easily rewritten. But in long-term track competition, a new chapter has already begun. $BTC ‌
