Mitra

Federated social network with smart contracts.

Built on ActivityPub protocol, self-hosted, lightweight. Part of the Fediverse.

Unique features enabled by blockchain integration:

• Sign-in with a wallet. A combination of domain-based and key-based identity.
• Donations.
• Recurring payments. Subscribers-only posts.
• Token-gated registration (can be used to verify membership in some group or to stop bots).
• Converting posts into NFTs.

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

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

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

Matrix chat: #mitra:halogen.city

Requirements

• Rust 1.54+ (when building from source)
• PostgreSQL 12+
• IPFS node (optional, see guide)
• 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.

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.

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.
