Estonia's eRoad system includes a blockchain - predating Bitcoin by a year or so in fact - for recording any accesses and changes to official data with the goal of being able to detect breaches and/or corruption sooner. The country's own instance of the platform has about ten nodes IIRC, mostly operated by various government bodies but a few operated by other organisations - again IIRC including its main university and somewhere in Lithuania as well?
