Yes, governments are building on existing blockchains or else trying to push Start ups to develop applications for governmental purposes. But a lot of it makes sense - e.g. Establishing polls about the public opinion regarding important topics on the blockchain with access via citizenship-card. So they get public opionion before discussion at parliament. Maybe blockchain helps to get the classic governmental descissions more democratic.

This posting is especially for my home country - Austria. However - all over Europe blockchain initiatives start.
