Garble - secure multiparty computation

[sanity]

Tandem: https://sine.foundation/tandem

Lets you define simple functions in a Rust-like language where Alice provides one input and Bob provides the other. Alice and Bob can then calculate the output of the function without disclosing their input to the other party.

It's unclear how complex the programs can get, their examples are functions that do simple operations like multiplications and comparisons, I suspect something like calculating SHA256 wouldn't be practical. Here is more information on what the language looks like and is capable of.

This kind of tool seems likely to have applications with Locutus although I don't yet have a specific use case in mind.
