Olsztyn, Poland is reportedly the get-go city in the world to leverage Ethereum'due south blockchain to aid the provision of emergency services, offering yet another tangible use case for distributed ledger technology.

Olsztyn has completed a successful trial run of SmartKey, a bridging applied science that connects blockchain with physical assets, to aid in police, fire and ambulance services.
