TLDR
- Chun Wang, co-founder of F2Pool, is confident that Bitcoin will withstand threats from quantum computing.
- Wang dismisses concerns about quantum computers breaking Bitcoin’s SHA-256 hashing algorithm.
- Recent advancements in quantum computing by companies like Google and IBM do not pose an immediate risk to Bitcoin.
- Wang emphasizes the importance of making Bitcoin latency-tolerant for future interplanetary use.
- Wang envisions Bitcoin as the primary currency for future space settlements instead of short-lived altcoins.
Chun Wang, co-founder of F2Pool, believes fears over quantum computing’s potential to disrupt Bitcoin (BTC) are overblown. Wang, the first Bitcoiner to travel to space, dismisses concerns that quantum computers will break Bitcoin’s security. He confidently stated that those fearing quantum attacks have “never written a single line of quantum code.”
Quantum Computing and Bitcoin’s SHA-256 Algorithm
Recent advancements in quantum computing have fueled worries about Bitcoin’s SHA-256 hashing algorithm. Companies like Google, Microsoft, and IBM are developing quantum technologies, including the Willow, Majorana 1, and Blue Jay projects. Despite these developments, quantum computers remain largely unproven in practical applications.
Wang, however, remains unconcerned about quantum threats to Bitcoin. He argues that the technology is still far from being capable of breaking Bitcoin’s cryptography.
“Instead of worrying about quantum computing, focus on making Bitcoin latency-tolerant,” he emphasized.
BTC’s Role in an Interplanetary Civilization
Looking ahead, Wang envisions Bitcoin playing a crucial role in an interplanetary civilization. He believes that by the time humans settle on Mars, quantum computers will not be able to crack Bitcoin.
“Bitcoin must be the currency for space settlements, not some fleeting altcoins,” Wang said.
I’d bet that by the time humans settle on Mars and economic activity already begins there, quantum computers still won’t have cracked secp256k1. Instead of wasting time worrying about quantum computing, it makes far more sense to think about how to make Bitcoin latency-tolerant,… https://t.co/vycgtlWwKv

Wang’s mission to space as part of the Fram2 mission reinforced his vision. During this mission, Wang and his crew performed scientific experiments, including the first X-ray observations in space. He is now focused on ensuring that Bitcoin can thrive in future interplanetary environments.
