What would be the fastest way to implement Dominant Assurance Contracts (which depend on multisignature transactions) with Monero?

Question

I think that dominant assurance contracts are a significantly overlooked or poorly explored idea for the entire cypherpunk and cryptocurrency community.

I'd like for all of us to do more exploration with it, but before that's possible there needs to be some implementation of it. So, what's the quickest, cheapest way to get a script that allows for a dominant assurance contract to be executed using Monero?

Answer 1

There is no simple built-in multisig option for now with Monero, we'll have to wait for RingCT and the multisig extension built on it.

So for now, probably there is no option to implement it at all.
