With the rapid advancements in quantum computing technology by major companies like Google, the threat quantum computing poses to Bitcoin's security cannot be underestimated. Over the weekend, renowned investment firm a16z even published a long article discussing how blockchain can address this threat. Here are a few takeaways from me: - Quantum computing breaking blockchain is just a matter of time, with a small probability of happening in about 5-10 years. - Bitcoin's current valuation already factors in the quantum threat. - Considering the efficiency of blockchain governance, developers and the community need to prepare in advance and push forward post-quantum solutions as soon as possible. - Regular users should avoid reusing addresses, as these addresses' private keys could be easily compromised in the quantum era. - Keep an eye on quantum-resistant projects. What do you all think about the quantum threat? Leave your thoughts in the comments below!
