Quantum computing threat controversy heats up: Two major camps in the Bitcoin community hold their own opinions

The Bitcoin development ecosystem has recently sparked intense discussions over the threat posed by quantum computing, with clear differences in industry opinions. Blockstream co-founder Adam Back recently stated that the threat of quantum computing to cryptocurrencies remains in its early stages and is unlikely to cause real harm to Bitcoin in the short term (the next decade).

Optimistic Viewpoint: The Threat Is Overhyped

Adam Back’s stance represents the view of some industry technical experts — while quantum computing theoretically challenges current cryptography, there is still a long way to go before practical applications are realized. He believes that within this time window, the Bitcoin ecosystem has enough time to upgrade its technology and implement protections.

Cautious Concerns

In contrast, Nic Carter, a partner at Castle Island Ventures, adopts a more cautious attitude. He points out that the industry’s downplaying of quantum risks is creating negative chain reactions — such “no need to worry” statements are blocking capital inflows from investors and even directly impacting Bitcoin’s market price.

Behind the debate lies a fundamental disagreement over the timeline and priorities for risk assessment. This discussion also reflects the differing attitudes within the Bitcoin community when it comes to addressing emerging technological threats.
