Adam Back, the president of Blockstream, minimizes concerns about the risks that quantum computers could pose to the Bitcoin network. Responding to worries raised by some Bitcoin investors, Back emphasizes that these threats could emerge in 20-40 years. Believing that over-dramatizing the issue creates an unnecessary panic atmosphere, Back argues that Bitcoin’s current architecture is not under such immediate threat.

The Security Foundation of Bitcoin: Not Encryption, but Signatures

An important point highlighted by Back regarding how security is maintained in Bitcoin’s design is that the network’s protection relies not on cryptographic encryption systems but on digital signature mechanisms. This fundamental difference plays a critical role when assessing the potential impact of quantum computers. According to Back’s perspective, current quantum technology has not yet reached a level that truly endangers Bitcoin, and existing solutions are sufficient for now.

The Need to Focus on Long-Term Security Strategies

Adam Back emphasizes that the Bitcoin community must develop realistic and consistent security plans. Instead of getting caught up in speculation and concerns about immediacy, the focus should be on technical improvements and protocol enhancements that can be made in the long term. This approach provides the opportunity to improve Bitcoin’s technical infrastructure and prepare in advance for possible risks.
