## ⚙️ Installation
### Prerequisites
- Golang 1.23 or higher is required to build and run the project. You can find the installer on
the official Golang [download](https://go.dev/doc/install) page.
- [Rust](https://www.rust-lang.org/tools/install) 1.80.1 or higher.
- A C compiler: `gcc` or `clang`.
- Install some dependencies on your system:
- macOS
```bash
brew install jemalloc
brew install pkg-config
make install-deps
```
- Ubuntu
```bash
sudo apt-get install -y libjemalloc-dev libjemalloc2 pkg-config libbz2-dev
make install-deps
```
- To ensure a successful build, you either need to synchronize the tags from the upstream repository or create a new tag.
### Build and Run
```shell
make juno
./build/juno
```
Use the `--help` flag for configuration information.
Flags and their values can also be placed in a `.yaml` file that is passed in through `--config`.
### Run with Docker
To run Juno with Docker, use the following command. Make sure to create the `$HOME/juno` directory on your local machine before running the command.
```shell
docker run -d \
--name juno \
-p 6060:6060 \
-v $HOME/juno:/var/lib/juno \
nethermind/juno \
--http \
--http-port 6060 \
--http-host 0.0.0.0 \
--db-path /var/lib/juno \
--eth-node
```
You should replace ` `with your actual Ethereum node address.
If you're using Infura, your Ethereum node address might look something like: `wss://mainnet.infura.io/ws/v3/your-infura-project-id`.
Make sure you are using the websocket URL `ws`/`wss` and not the http URL `http`/`https`.
To view logs from the Docker container, use the following command:
```shell
docker logs -f juno
```
## 📸 Snapshots
Use the provided snapshots to quickly sync your Juno node with the current state of the network.

```
### Run Juno Using Snapshot
1. **Download Snapshot**
Fetch the snapshot from the provided URL:
```bash
wget -O juno_mainnet.tar https://juno-snapshots.nethermind.dev/files/mainnet/latest
```
2. **Prepare Directory**
Ensure you have a directory at `$HOME/snapshots`. If it doesn't exist yet, create it:
```bash
mkdir -p $HOME/snapshots
```
3. **Extract Tarball**
Extract the contents of the `.tar` file:
```bash
tar -xvf juno_mainnet.tar -C $HOME/snapshots
```
4. **Run Juno**
Execute the Docker command to run Juno, ensuring that you're using the correct snapshot path `$HOME/snapshots/juno_mainnet`:
```bash
docker run -d \
--name juno \
-p 6060:6060 \
-v $HOME/snapshots/juno_mainnet:/var/lib/juno \
nethermind/juno \
--http \
--http-port 6060 \
--http-host 0.0.0.0 \
--db-path /var/lib/juno \
--eth-node
```
After following these steps, Juno should be up and running on your machine, utilizing the provided snapshot.

### Phase 3: Starknet decentralization begins 🚧
Juno can synchronize Starknet state from other full nodes with the aim of decentralizing Starknet by removing the dependency from the centralized sequencer.
Snap sync is implemented, significantly reducing sync times.
### Phase 4: Juno becomes a Starknet Sequencer 🔜
The decentralization of Starknet is complete! Juno becomes a sequencer and participates in L2 consensus to secure the network. Juno has multiple modes of operation:
• Light client: provides fast permissionless access to Starknet with minimal verification.
• Full Node: complete verification of Starknet state along with transaction execution.
• Sequencer: secure the network by taking part in the L2 consensus mechanism.
