validator_rust

Bundlr validator implementation in Rust

Prerequisites

Arweave Wallet

Generate an Arweave wallet, export it to a Json file and save in the project repository (E.g ./wallet.json)

Alternatively, you can use the wallet generator tool in this repository. Just run:

cargo run --bin wallet-tool create > wallet.json

Environment Variables

The following environment variables need to be defined:

DATABASE_URL="postgres://<username>:<password>@localhost/bundlr"                                // Path to store database file
BUNDLER_PUBLIC="OXcT1sVRSA5eGwt2k6Yuz8-3e3g9WJi5uSE99CWqsBs"    // Bundler public key
VALIDATOR_KEY="./wallet.json"                                   // Path to arweave wallet file
BUNDLER_URL="https://node1.bundlr.network"                      // Bundler Node url

You can find an example in the example.env file. Copy them by running:

cp example.env .env

Getting started

After cloning the repo and setting up all the prerequisites, just run:

cargo build
cargo run

The client will start validating

Running tests

To run tests, we need an empty postgres database with migrations executed. Database needs to be reset with every time tests are run.

# Start docker container for the database
docker compose -f docker-compose.test.yml up -d

# Run migrations
diesel migration run --database-url postgres://bundlr:bundlr@localhost/bundlr

# Run tests
cargo test

or you can run everything with the following oneliner:
