Well, transparency works both ways doesn't it? Governments are largely not transparent. If they were, you wouldn't have something like the CIA, Guantanamo bay and the entire surveillance enterprise. I am just quoting the US government as an example but most governments are more or less the same.

Expecting others to be transparent, while governments go on about their private secret activities is very unfair.

Case in point - why hasn't any government adopted any open blockchain till date ? I mean, there are gazillions of operations that the government can use a blockchain for. OK, forget about a blockchain, at least an open distributed ledger ? For instance, all public RFPs and contracts can go on a queryable open distributed ledger. Why hasn't this happened yet ?

Let the governments show a spend log of every tax penny collected and then we'll talk about transparency.
