README
| Semaphore is a generic privacy layer. Leveraging zero-knowledge technology, users can prove their membership in groups and send messages (extending from votes to endorsements) off-chain or across EVM-compatible blockchains, all without revealing their personal identity. |
| ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
The core of the Semaphore protocol is in the [circuit logic](/packages/circuits/scheme.png). However, Semaphore also provides [Solidity contracts](/packages/contracts) and JavaScript libraries to make the steps for offchain proof creation and onchain/offchain verification easier. To learn more about Semaphore visit [semaphore.pse.dev](https://semaphore.pse.dev).

## 🛠 Install
Clone this repository:
```bash
git clone https://github.com/semaphore-protocol/semaphore.git
```
And install the dependencies:
```bash
cd semaphore && yarn
```
## 📜 Usage
Copy the `.env.example` file as `.env`:
```bash
cp .env.example .env
```
And add your environment variables.
### Code quality and formatting
Run [ESLint](https://eslint.org/) to analyze the code and catch bugs:
```bash
yarn lint
```
Run [Prettier](https://prettier.io/) to check formatting rules:
```bash
yarn format
```
Or to automatically format the code:
```bash
yarn format:write
```
### Conventional commits
Semaphore uses [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/). A [command line utility](https://github.com/commitizen/cz-cli) to commit using the correct syntax can be used by running:
```bash
git commit
```
It will also automatically check that the modified files comply with ESLint and Prettier rules.
### Testing
Run [Jest](https://jestjs.io/) to test the JS libraries:
```bash
yarn test:libraries
```
Run [Mocha](https://mochajs.org/) to test the contracts:
```bash
yarn test:contracts
```
Or test everything with:
```bash
yarn test
```
### Build libraries & compile contracts
Run [Rollup](https://www.rollupjs.org) and [TheGraph](https://www.npmjs.com/package/@graphprotocol/graph-cli) to build all the packages and the subgraph:
```bash
yarn build
```
Compile the smart contracts with [Hardhat](https://hardhat.org/):
```bash
yarn compile:contracts
```
### Documentation (JS libraries)
Run [TypeDoc](https://typedoc.org/) to generate a documentation website for each package:
```bash
yarn docs
```
The output will be placed on the `docs` folder.
### Releases
Bump a new version with:
```bash
yarn version:bump
# e.g. yarn version:bump 2.0.0
```
It will create a commit and a git tag that will need to be pushed on the main branch. A workflow will be triggered and will
publish the Semaphore packages on [npm](https://www.npmjs.com/) and release a new version on Github with its changelogs automatically.
