Because I Am Bored
If you strip the envelope of crypto-hate, this is a really interesting idea to put transaction-validators on space-probes that are rapidly moving away from Earth.<p>There, they <i>can't</i> be coerced by terrestrial bullies - be they 'authorities' or criminals – or enlisted into new cartels. They'll be running the same audited code for as long as they're in operation, unless later probes can outrace them.<p>And if the economic effort that had been spent trying to corrupt terrestrial nodes is instead directed to ever-more-cost-efficient planet-leaving tech - that's a win, too!<p>(Maybe ʻOumuamua was the leading edge of some other solar system's cryptominer cone?)
