About

Papyrus is a StarkNet full node written in Rust.

Getting Started

Compiling and running papyrus

Prerequisites

• Rust

You can build and run a papyrus node with the default configuration by running:

mkdir data
cargo run --release --package papyrus_node --bin papyrus_node

Configuration

Papyrus supports configuration from command-line arguments and a configuration yaml file. In case both are provided, the command-line arguments take precedence. The default path for the configuration file is config/config.yaml. You can override this path using the --config_file command-line argument. See the default configuration file for available options. Note that the configuration file can be partial or even empty. You can check the available command-line arguments by running:

cargo run --release --package papyrus_node --bin papyrus_node -- --help

Running papyrus with Docker

Prerequisites

• Docker

Command line

You can run a papyrus node with the default configuration by running:

docker run --rm --name papyrus\
  -p 8080-8081:8080-8081 \
  -v <local-host-data-path>:/app/data \
  ghcr.io/starkware-libs/papyrus:dev

Notes

• The container must have write access to <local-host-data-path>. A possible way to assure this is to create the <local-host-data-path> directory (only the first time you run papyrus) and add --user "$(id -u):$(id -g)" to the docker run command.
• You must include the dev tag which keeps track of our development branch and contains the most up-to-date code. Once we have official releases we will add a latest tag for the latest release.
• Currently, there is no automatic upgrade mechanism. Make sure to periodically pull the latest image and re-run the node.

Memory usage

The Papyrus node will use all the RAM it can in order to cache the storage.

If you're not running any other applications on your machine, this is the recommended behavior.

Otherwise, you can limit the node's memory usage by running it in a container with a limited memory. Note that it might make the node less efficient as it will decrease the caching of the storage.

This can be done by adding the flag --memory 1g (For a 1GB limitation) to the command in the Docker section. The full command should be

docker run --rm --name papyrus\
  -p 8080-8081:8080-8081 \
  -v <local-host-data-path>:/app/data \
  --memory <memory-limit>
  ghcr.io/starkware-libs/papyrus:dev

For more information, see Docker's documentation.
