Traditional thinking cannot imagine that pure software can achieve absolute security in theory. This is due to cognitive misconceptions and the early development stage of security concepts. The growth history of computers since their invention is an evolutionary history of self-development and self-destruction. Systems strive to maximize compatibility and openness, adapt to various hardware and software, and then struggle to prevent bad actors from exploiting these open interfaces. For personal operating terminals, this is a normal developmental law, but for IoT devices, it's unnecessary to completely open the core underlying and open control interfaces. These can be designed as dedicated processing systems, which inherently eliminate over 90% of intrusion opportunities. However, VoidChain achieves absolute security by breaking through the traditional world's perception of software security. It argues that only hardware trust roots are reliable, but VoidChain proposes that software trust roots can achieve or even exceed the theoretical security level of hardware trust roots. Based on this, combined with the idea of automatically customized processing systems, it can completely shatter the conventional belief that software cannot achieve absolute security. In fact, according to VoidChain's security standards, even Bitcoin currently lacks security. Most nodes run on the Internet, and other CPUs may have undisclosed micro-kernel control modules. This means that CPU manufacturers can control any existing public chain at zero cost if they want to attack, but VoidChain prevents them from doing so. Theoretically, CPUs cannot easily achieve their goals. This is the future world - a consensus rule world truly free from any human intervention.
