Following a successful trial, Olsztyn, Poland is the first city in the world to use blockchain to assist their emergency services, thanks to SmartKey, the blockchain connection platform.
The SmartKey team has successfully connected an Ethereum smart contract to a Teltonika smart key device and app which will enable fire, ambulance and police teams to enter any part of the closed district or any secure building within the city safely and securely, without having to track down a keyholder or wait for permission.
