Sounds like this definitely requires a good arbitration and mediation clauses incorporated in the smart contracts. Quite interesting really that people have decided to use blockchain for marriage. I wonder if has been done anywhere else besides Nevada as well and what was the story behind starting doing this in the first place.
Here is what the article mentions as the positive benefits from using blockchain:
"This story shows and demonstrates the true potential of blockchain technology. The powers it can lend to any system with easy, fast implementation and low cost are irreplaceable. There are many different aspects of public services where blockchain can bring about a revolution. No more standing in long queues and waiting for your turn while filling out and printing dozens of forms. It can all happen with a few clicks."
Quick, secure, cheap, user-friendly.
I feel like standing in long queues is a problem that a lot of countries have overcome anyway. At least in many countries that have taken use of digitalisation and let people fill in forms online. Which quite a few big countries unfortunately don't do. So yes, blockchain would be a solution to speed up processes. However, before implementing blockchain in several life aspects institutions should be able to go over and function digitally first.
For example, instead of when opening a bank account in the UK you don't have to go in to the bank to schedule an appointment to go there back on another day to actually fill in the application, instead, you could apply for your bank account digitally and provide your information that way. And only after that they have fixed this issue and taken the step towards being digitally present, we can start discussing about implementing blockchain for these services.
