Understand the project
Practical overview
When it fits
Use Semaphore when an application needs to verify membership or accept an interaction while preserving the participant’s identity. It is suited to both off-chain designs and applications using EVM-compatible blockchains.
Who it is for
- Developers building privacy-preserving blockchain applications
- Teams creating anonymous voting, endorsement or attestation systems
- Builders needing membership-gated interactions without public identity disclosure
- Developers implementing off-chain or EVM-compatible on-chain verification
Documented uses
- Prove that a participant belongs to a defined group
- Create zero-knowledge proofs for off-chain interactions
- Verify proofs on-chain or off-chain
- Enable anonymous messages, votes, endorsements or participation claims
Before you choose
Requirements & limits
The repository is public and MIT-licensed. It provides a TypeScript-led codebase with Solidity, Circom and zero-knowledge proof components, plus JavaScript libraries and API documentation.
- Choose it when group membership must be proven without disclosing personal identity.
- The protocol supports both off-chain verification and use across EVM-compatible blockchains.
- Integration involves circuit logic, Solidity contracts and JavaScript libraries rather than a standalone end-user application.
- The repository documents messages, votes and endorsements as interaction patterns.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
