Garbling in the wild (soft question) I am curious to know whether (Yao's) garbled circuits are actually deployed in practice. There has a lot of works on optimising garbled circuits (e.g., here and here) and I am interested in whether these simply of theoretical interest or with practical applications in mind. (A quick Google search did not yield much.)
Bolt labs uses Garbled circuits (from emp-toolkit) for channel management between the merchant and the customer. More on their blog post
In general, I don't think Garbled circuits is one of the most efficient MPC protocol out there for most tasks. So you're not likely to find many practical applications.
