Mitra

Federated micro-blogging platform and content subscription service.

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

Subscriptions provide a way to receive monthly payments from subscribers and to publish private content made exclusively for them.

Supported payment methods:

• Monero.
• ERC-20 tokens (on Ethereum and other EVM-compatible blockchains).

Other features:

• Sign-in with a wallet.
• Donation buttons.
• Token-gated registration (can be used to verify membership in some group or to stop bots).
• Converting posts into NFTs.
• Saving posts to IPFS.

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

Code

Server: https://codeberg.org/silverpill/mitra (this repo)

Web client: https://codeberg.org/silverpill/mitra-web

Ethereum contracts: https://codeberg.org/silverpill/mitra-contracts

Requirements

• Rust 1.54+ (when building from source)
• PostgreSQL 12+
• IPFS node (optional, see guide)
• Ethereum node (optional)
• Monero node and Monero wallet (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 USER mitra WITH PASSWORD 'mitra';
CREATE DATABASE mitra OWNER mitra;

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:

CREATE USER mitra WITH PASSWORD 'mitra';
CREATE DATABASE mitra OWNER mitra;

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.

Monero

Install Monero node or choose a public one.

Configure and start monero-wallet-rpc daemon.

Create a wallet for your instance.

Add blockchain configuration to blockchains array in your configuration file.

Ethereum

Install Ethereum client or choose a JSON-RPC API provider.

Deploy contracts on the blockchain. Instructions can be found at https://codeberg.org/silverpill/mitra-contracts.

Add blockchain configuration to blockchains array in your configuration file.

Development

Start database server

docker-compose up -d

Test connection:

psql -h localhost -p 55432 -U mitra mitra

Start Monero node and wallet server

(this step is optional)

docker-compose --profile monero up -d

Run web service

Create config file, adjust settings if needed:

cp config.yaml.example config.yaml

Compile and run service:

cargo run

Run CLI

cargo run --bin mitractl
