A privacy gadget for creating anonymous proof of membership on Ethereum.
| Semaphore is a zero-knowledge gadget which allows Ethereum users to prove their membership of a set without revealing their original identity. At the same time, it allows users to signal their endorsement of an arbitrary string. It is designed to be a simple and generic privacy layer for Ethereum DApps. Use cases include private voting, whistleblowing, mixers, and anonymous authentication. |

The core of the Semaphore protocol is in the circuit logic. However Semaphore also provides Solidity contracts and JavaScript libraries (i.e. @zk-kit/identity and @zk-kit/protocols) to make the steps for offchain proof creation and onchain verification easier.

The following is a list of our deployed onchain verifiers. Each Verifier.sol contract can be used with a binary tree of a certain depth. If depth = 20 the tree can have maximum 2^20 leaves (a group of 1048576 members).
