Description
The DoTS platform intially proposed and presented by Tan and Kaviani promises to solve many of these issues by addressing the practical needs of distributed trust applications as a software development kit for developers to build applications with distributed trust. In this paper, we present mid- and low-level architectural modifications to the DoTS platform in order to make the platform and API more accessible to developers, while fulfilling its original vision.
We demonstrate both that our modifications maintain the simplicity of developing new applications on top of DoTS, with our secret key recovery and (n, t)-threshold ECDSA signing applciations requiring fewer than 500 lines of integration code each, and we demonstrate that it is equally easy to port existing applications to utilize the DoTS platform, replacing over 2,600 lines of code in MP-SPDZ with simple function invocations.
We show that, by leveraging the unique conditions of such applications typically executing in distinct trust domains in geographically separated regions, applications utilizing the updated DoTS design suffer as little as 6.4-9.5% overhead compared to ad hoc, complex, application-specific network solutions.
