Inspiration Behind TrueConsensus 🌟

It all started with our shared frustration over opaque ranking sites and clunky group chat polls. We were fed up with hidden algorithms that left users guessing how votes were counted, breeding distrust and skepticism. That’s when TrueConsensus was born—a platform designed to shatter the mystery and revolutionize voting. By eliminating the need to create polls in group chats, we deliver a seamless, transparent experience where every vote counts right on the website.

Why We Built TrueConsensus 🚀

Our mission is clear: restore trust and clarity to the voting process. We built TrueConsensus as an open-source platform featuring an algorithm that anyone can inspect, verify, and even modify. This isn’t just about voting but about empowering you with complete visibility and control over the process.

Technology Stack 🛠️

Frontend: Next.js, Tailwind CSS
Backend: NestJS, TypeORM
Database: PostgreSQL
Authentication: Firebase
Hosting: Vercel (frontend) & Render (backend)
Languages: TypeScript and JavaScript

Challenges and Accomplishments 🏆

One of our toughest challenges was ensuring that every authenticated user could vote only once, maintaining the integrity of our system. Crafting a transparent algorithm using the Condorcet voting method demanded innovative thinking and rigorous planning. The Condorcet method is a voting system that identifies the candidate who would win a one-on-one election against each of the other candidates. This method ensures that the most broadly preferred candidate wins, rather than just the one with the most votes. Despite these hurdles, we’re proud to have built a platform that invites community collaboration and empowers users to redefine how voting should work.

Created by

I designed the frontend voting page using Tailwind CSS and React. My goal was to ensure that the interface is easy to use, giving users a smooth experience while voting.

Masruful Islam
I came up with the initial idea, and led the development of the backend. On the backend, we used Nest.js, PostgreSQL, Typescript, and TypeOrm. I helped specifically by designing the database and then implementing the tables in Nest.js, and then coding routes to each table. Then I use Ian's work which was to make a firebase auth guard, to protect specific routes. ex. from the auth guard, we verify the token but also get the user_id, so if a user gives us the token and makes a vote, we will automatically know who made the vote. Finally, i helped with making the ranked pairs algo implementation.
