Conclusion
Effective gun control in the US requires the the number of guns available in society be limited in ways that are compatible with both the constitution and public health. The blockchain protocol is the most accurate system to track gun flow from manufacturer to end user, and track sales from one gun owner to another. It allows for better privacy than existing background check systems, and simultaneously link ownership of a specific gun to a specific individual in an immutable manner. A blockchain based digital gun safe would improve the implementation of existing gun laws, maintaining privacy and improving gun control. Gun control should not be viewed in isolation as a legal issue that can be solved simply by the creation of more laws. Blockchain technology, when applied to the financial systems and businesses, can potentially help create a climate where the rates of suicide and interpersonal violence are minimized.
