Navigating Euclidean Distances in Secure Multi-Party Computation with Nada DSL

[emanuel-skai]

Hello GitHub Community! 👋

I'm excited to share my journey building a project using the Nada Domain Specific Language (DSL), part of the Nillion Network, focused on securely calculating Euclidean distances for similarity measurement in multi-party computation environments. The goal is to enable privacy-preserving operations that could benefit fields such as healthcare, finance, and beyond where data privacy is paramount.

🚀 What I'm Building and Why
The project involves computing Euclidean distances squared between vectors securely, ensuring that the data from different parties remains confidential while allowing collective insights. This could revolutionize how sensitive data is utilized collaboratively, maintaining privacy and compliance.

📖 Lessons and Progress
Throughout this process, I've navigated various challenges and learned a great deal about secure computations:

MPC's Complexity: Multi-party computation (MPC) is fascinating and offers a unique opportunity to think creatively and solve problems innovatively.
Debugging in MPC: Unlike traditional programming, debugging in an MPC environment like Nada involves thinking about data privacy continuously, which introduces unique challenges and solutions.
Performance Optimization: Ensuring computations are efficient while secure has been a key focus, requiring careful balancing.
💡 Tips for Developers
Here are a few tips if you're venturing into secure multi-party computation or using Nada DSL:

Start Small: Begin with simple computations to understand how operations are handled securely without compromising performance.
Embrace the Nada Toolkit: Even as a devoted Python enthusiast, I've found that building projects with Nada and utilizing its testing and debugging commands have been extremely useful.
Program Simulator: For rapid prototyping and testing, the program-simulator is invaluable, offering speed and agility without compromising on security.
