With proper legislation blockchain technically allows making all government spendings and documentation orders of magnitude more transparent then they are now.
Pushing for this legislation is a common interest of... Well for all the people.
There is a case for my country where Transparency International pushed our government to move their land ownership registry to blockchain and Ukrainian government did it. Now there is need to push for everything else - documents, databases, taxes and expenses.
Do you know about any organized movements that push for this?
I would like to see this implemented. Some political parties already list their expenses online, but the blockchain can be way more transparent than what legacy banking system has to offer.
I really doubt they would stick to receiving payments on public addresses tho. All they need is accept payments in other addresses or even in Monero and don't report that..
