This might be unpopular but - TAX COLLECTION - Automatically. The Govt wastes more money than anyone so streamlining tax collection could be a huge revenue source. Sales taxes could be automatically collected with transactions logged on the block chain by using a blockchain enabled debit card when purchases are made with taxes directly remitted to the states (In USA). Income taxes can be the same by having paychecks deposited to the same. People could "log in" to their blockchain debit card and pay their bills and have everything recorded on the blockchain without having to go crazy saving receipts.
