Constellation Network, a US blockchain infrastructure company, recently released the "Digital Evidence" system, which is based on blockchain technology and aims to provide law enforcement and public service agencies with tamper-proof data storage solutions. The company has previously worked with the US Department of Defense to develop the "Iron SPIDR" project for six years. The system can be used for data collection in scenes such as police vehicles and fire equipment, and can be integrated with Panasonic TOUGHBOOK devices. Constellation said that the technology can help agencies reduce compliance costs, and the "smart authentication" tags it generates can improve data credibility. Currently, the system is being tested in multiple pilot scenarios, including public safety, retail analysis, and intellectual property protection.
