Why Choose This Project?

Feedback systems today are often centralized, prone to tampering, and lack anonymity. Public surveys and opinion polls require transparency to build trust in democratic, educational, or product-based ecosystems.

This On-Chain Survey System stores surveys and votes securely on a blockchain using smart contracts — ensuring transparency, anonymity, and immutability. It’s ideal for institutions, public forums, or open-source product feedback systems.
