Hello!
I'm interested in the possibility of integrating an escrow mechanism into a blockchain. I know that escrow is often used to protect the interests of parties in various transactions, and I would like to know if similar functionality can be implemented using blockchain technology.
Basic escrow is a 2-of-3 multisig.
I think a trustless escrow would would have to be done in a layer on top of Bitcoin because it is aware of only a very limited set external criteria.
