Researchers have uncovered a method to secure Bitcoin against future quantum attacks without requiring a hard fork or protocol update. This breakthrough means the network could theoretically withstand quantum decryption without changing its core code, potentially preserving its current structure. However, the solution comes with a hefty price tag—users might face $75–150 in GPU computing costs per transaction, making it impractical for everyday use. While this approach highlights Bitcoin's adaptability, the high costs underscore the need for more affordable solutions. The findings spark a crucial debate about balancing quantum security with accessibility, as the crypto community prepares for the looming quantum era.
