A challenge organized by OpenMined Community.
The project is being developed as part of the #30DaysOfFLCode challenge. Each checkpoint represents a milestone, with the first goal being to complete at least Checkpoint 1 during the challenge.
Inspired by
Ionesio's tutorial, the initial coding task was to create a
repository for the voting API for SyftBox. In its first version, the API simply sums the values stored in
public/value.txt across all Datasites.
apis folder in SyftBox.
public/value.txt file with a number inside it.
I enhanced the aggregation logic to specifically address the binary voting requirements of Checkpoint 1. Here’s what’s new:
Validated Votes:
Ensured that only binary
votes (0 for No and 1 for Yes) are
counted. Any invalid or missing votes are now tracked separately to
maintain data integrity.
Mean Calculation:
Instead of simply summing
the votes, the system now calculates the mean of
all valid votes. This mean value helps determine whether the
election result leans closer to 0 (No) or
1 (Yes), providing a clearer understanding of the
overall outcome.
Outcome:
These enhancements improve the accuracy of
vote aggregation and ensure that only valid votes contribute to the election
result. Participants with invalid or missing votes are now clearly
identified, enhancing transparency and reliability.
To enhance privacy in our voting system, I’ve delved into (MPC). Here’s a simple analogy to illustrate its concept:
Imagine a group of employees wants to calculate the average salary without disclosing individual salaries. Each employee generates random numbers that sum to their salary and shares one number with each colleague. By summing the received numbers, each person gets a partial total. Summing all partial totals gives the overall sum, which, when divided by the number of employees, reveals the average salary—achieved without exposing individual salaries.
I focused on designing the flow of information to ensure privacy during the vote. While the implementation is still a work in progress, I’m getting closer to a robust privacy-preserving mechanism.
The repository’s README now includes instructions on:
Today, I want to take a moment to express my gratitude for the amazing OpenMined community, specially:
