Built on [ActivityPub](https://activitypub.rocks/) protocol, self-hosted, lightweight.

Unique features enabled by blockchain integration:

- [Sign-in with a wallet](https://eips.ethereum.org/EIPS/eip-4361).
- Donations.
- Paid subscriptions.
- Proving membership with a token.
- Converting posts into NFTs.

Currently only Ethereum and other EVM-compatible blockchains are supported.

Smart contracts repo: https://codeberg.org/silverpill/mitra-contracts

Frontend repo: https://codeberg.org/silverpill/mitra-web

Demo instance: https://mitra.social/ (invite-only)

Matrix chat: [#mitra:halogen.city](https://matrix.to/#/#mitra:halogen.city)

## Requirements

- Rust 1.54+ (when building from source)
- PostgreSQL 12+
- IPFS node (optional, see [guide](./docs/ipfs.md))
- Ethereum node (optional)

## Installation

### Building from source

Run:

```
cargo build --release --features production
```

This command will produce two binaries in `target/release` directory, `mitra` and `mitractl`.

Install PostgreSQL and create the database.

Create configuration file by copying `contrib/mitra_config.yaml` and configure the instance. Default config file path is `/etc/mitra/config.yaml`, but it can be changed using `CONFIG_PATH` environment variable.

Start Mitra:

```
./mitra
```

An HTTP server will be needed to handle HTTPS requests and serve the frontend. See the example of [nginx configuration file](./contrib/mitra.nginx).

Building instructions for `mitra-web` frontend can be found at https://codeberg.org/silverpill/mitra-web#project-setup.

To run Mitra as a systemd service, check out the [systemd unit file example](./contrib/mitra.service).

### Debian package

Download and install Mitra package:

```
dpkg -i mitra.deb
```

Install PostgreSQL and create the database. Open configuration file `/etc/mitra/config.yaml` and configure the instance.

Start Mitra:

```
systemctl start mitra
```

An HTTP server will be needed to handle HTTPS requests and serve the frontend. See the example of [nginx configuration file](./contrib/mitra.nginx).

cargo test
```

### Build for production

```
cargo build --release
```
