The Privacy and Scaling Explorations Team is sponsoring a dedicated round of grants for applications that integrate the Semaphore anonymous signaling protocol. Semaphore provides zero-knowledge primitives that enable developers to build powerful privacy preserving applications. With this grant round, we’re encouraging builders to try out these tools in real-world applications that matter to your communities.
Whether it’s talking confidentially with friends, anonymously broadcasting messages, or simply wanting to choose which aspects of our identity we reveal in which contexts, privacy allows us to express ourselves freely and without fear. Privacy is a tool that should be accessible to as many people as possible, and PSE’s goal is to foster a collaborative community to make access to privacy a reality in everyday life.
**If you’re a developer with an idea to use Semaphore for good, we want to hear from you!
Semaphore is designed to be a simple and generic privacy layer for decentralized applications (dApps) on Ethereum.
Semaphore is a zero-knowledge protocol that allows Ethereum users to prove their membership of a group and send signals such as votes or endorsements without revealing their original identity.
With Semaphore, you can allow your users to do the following:
You can integrate Semaphore into other primitives, POCs, or end-user applications. Below is a list of several apps already using Semaphore. They may give you an idea of what to build.
Unirep is a social media platform that uses anonymous reputation. Semaphore identities allow users to join with a unique identity, prove they’re eligible to post or give feedback, and choose how much of their stable identity they reveal in any given interaction.
Interep uses zero knowledge proofs to verify reputation from an existing account such as Github or Twitter without retaining any identifying information.
Zkitter is a decentralized social network based on Ethereum and ENS. It uses Semaphore for anonymous user identities.
Emergence incentivizes communities to participate or contribute to online meetings. The project uses Semaphore to preserve the anonymity of group members and was a finalist at the ETHMexico hackathon.
Surprise us with your creativity! But here are a few ideas for privacy-preserving applications we would love to see built out:
Anonymous chat for members of an organization or school
Prove professional skills, credentials, or certificates without revealing identity
Prove one does not have a criminal record without revealing identifying information
Privately share vaccination status
Privately share medical history
Privately prove income or residence to access government benefits and services
Privately prove the number of countries one can visit with a certain passport
Privately share one’s age
Grants are decided on a case-by-case basis. You can apply with more than one proposal so long as each proposal is unique and meets the requirements.
Ideas and projects at any stage are welcome:
Work in progress
Fully fleshed-out project
Proposals must be in English
Work must be open source with a free and permissive license
Published work must be accessible by a URL
What we look for:
Potential impact on broadening the Semaphore community
Quality of contribution to the Semaphore ecosystem
Clarity, conciseness, and organization of documentation
Novelty in reducing the barrier of entry to zero knowledge and privacy applications
Overall quality and clarity of data analysis or data visualization.
Application dates: September 16th to October 28th, 2022

How can I learn more about Semaphore?
I have more questions, where do I go?
The best place to ask technical questions about the Semaphore protocol or questions about this grant round is in our Discord server.
We will also be at Devcon VI in Bogota. Come say hello if you’re in town! We will be located at the Temporary Anonymous Zone (TAZ) in the Community Hub.
You can also email questions to: email@example.com
What if I miss the deadline?
