Smart Wedding Contract on Ethereum
Christian Lanz

As far as I can see, the only advantage it has over a paper contract is that it doesn’t burn, and you could potentially prove you’re married (and the other functions), even if Austria gets nuked off the map entirely, because the blockchain exists wherever you flee, like New Zealand.

But then, I mean, couldn’t you also store and run that code from old-fashioned centralized data centers!?

I don’t quite understand why you would need Ethereum, or any other blockchain to do the above.
