Hypothetically, say I'm an independent politician, or a politician from a minor party, in a Governments senate. The ruling party or their opposition has promised me a diplomatic appointment after my term in parliament ends in return for my support in certain things. Given that politicians frequently lie, and if I leave parliament I will have minimal media clout thereafter, can I somehow use a smart contract or some kind of political manoeuvre to ensure compliance without revealing the nature of the agreement prematurely, which may damage the clout of my associates and political allies?
