I think there is a confusion with the terminology "secure computation from secret sharing". Let me try to clarify. There are two major settings for secure computation: the honest majority setting (out of $n$ parties, at most $(n-1)/2$ are dishonest) and the dishonest majority setting (up to $n-1$ parties can be dishonest). The two settings have a ...

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.

This really depends on which garbling scheme is used. Using the state-of-the-art half-gate scheme (here), your question has been the subject of a paper by Dupin, Pointcheval, and Bidan, which can be found here. The bottom line is: any such attack amounts to adding or removing NOT gates arbitrarily in the original circuit. Whether this can be used to leak the ...

It is more likely to find applications of secret-sharing based multiparty computation instead of garbled circuit-based. In fact, of the former type several applications can be found such as the sugar beet in Denmark or the analysis of gender income inequality in Boston (sorry, I’m on mobile and it’s hard to provide references). MPC based on garbled circuits ...
