Cargo Cartesi

Rust-specific toolkit for building DApps on Cartesi.

Motivation

The Cartesi ecosystem on its own is self-sufficient. It, however, requires learning some domain knowledge. To smooth-out the learning curve, we developed a toolkit that allows Rust developer of any level to build DApps on Cartesi using a high-level interface.

Requirements

• Rust
• Docker

Installation

Clone this repository, then run

cargo build -p cargo-cartesi

And put directory target/debug in your $PATH.

Usage

Create new DApp

Use the following command to create hello world DApp and build from there.

cargo cartesi new my-dapp

Creates a new DApp in my-dapp/ directory.

Build binary

In the DApp directory run:

cargo cartesi build

To build RISC-V specific binary. Cartesi machine is built on RISC-V architecture so that's the target we need.

Create file-system

Cartesi machine uses ext2 file-system. To embed the binary in an image that the machine can mount, run:

cargo cartesi create-fs

Build machine

To create Cartesi machine in an initial state, in the DApp directory run:

rm -rf pwd
mkdir pwd
cargo cartesi create-machine

The initial state is when the DApp runs on Cartesi machine until first yield. It will be stored in pwd/machine directory.

Run (one-shot)

To run binary on a Cartesi machine without rollups, in the DApp directory run:

cargo cartesi run

This is an experimental feature, the app runs on Cartesi machine but is not able to yield or do any other operation using MachineIo.
