Blockchain for public safety: A survey of techniques and applications

As an emerging technology, blockchain provides a range of advantages, such as decentralized and transparent data storage, secure access control, and enhanced data traceability. However, it is rarely applied in the field of public safety. This paper presents an in-depth survey of blockchain technology, focusing on its potential applications and implications within the field of public safety research. We explore the practical needs of multi-party data collaboration in emergency management and discusses the applicability and value of blockchain technology in this context. Additionally, this paper introduces and compares several popular blockchain platforms. By providing a comprehensive examination of blockchain technology and its potential benefits for public safety, this paper seeks to enhance understanding of the technology's capabilities, encourage further research, and inspire innovation in this domain.
