In police investigations, maintaining the integrity of the chain of evidence is paramount, so a distributed, hard-to-falsify record kept via blockchain could provide an added layer of security to the evidence-handling process. In addition, blockchain can be leveraged for flagging certain kinds of transaction patterns — giving police a heads up when an individual engages in suspicious financial activity.
Startups are innovating to bring these benefits to law enforcement. Chronicled is developing sealable, tamper-proof containers with near-field communications chips that register container contents through a blockchain system — creating an ideal solution for evidence management in law enforcement.
Elliptic, meanwhile, is developing a system to continually scan bitcoin registries, uncover complex relationships within the transactions, and flag suspicious transactions/histories for potentially alerting law enforcement.
