Whistleblower

Inspiration

Feedback and voting tools like Google Forms expose who said what. In schools, workplaces, and communities across Africa and the world, people self-censor because they fear retaliation. We asked: what if you could vote on anything honestly with zero fear?

What it does

Whistleblower is an anonymous community polling platform built on the Midnight blockchain. Anyone can:

• Create a poll on any topic
• Vote anonymously no name, no wallet address, no trace
• See results that are mathematically verified no fake votes, no double voting

The magic is zero-knowledge proofs. Your vote is verified as legitimate without ever revealing who you are.

How we built it

• Midnight blockchain - the privacy layer that makes anonymous voting possible
• Compact smart contracts - ZK circuits that verify voter eligibility and prevent double voting
• HTML/CSS/JavaScript - clean, simple frontend anyone can use
• Lace wallet -connects users to the Midnight network

Challenges we faced

As first-time blockchain developers, the biggest challenge was understanding zero-knowledge proofs and how Compact works. Setting up the Midnight local dev environment was also a steep learning curve. We pushed through by attending every workshop and reading the docs carefully.

What we learned

• How zero-knowledge proofs work in practice
• How to write Compact smart contracts on Midnight
• That privacy and usability don't have to be opposites

What's next

Whistleblower has real potential as a tool for student governance, community decisions, and anonymous HR feedback anywhere honest input matters. We want to deploy on Midnight mainnet and partner with universities across East Africa.
