README
Project Lotus - ่ฒ
Lotus is an implementation of the Filecoin Distributed Storage Network. For more details about Filecoin, check out the [Filecoin Spec](https://spec.filecoin.io).
## Building & Documentation
> [!NOTE]
> The default `master` branch is the dev branch, please use with caution. For the latest stable version, checkout the [latest release](https://github.com/filecoin-project/lotus/blob/master/LOTUS_RELEASE_FLOW.md#why-is-the-releases-branch-deprecated-and-what-are-alternatives).
For complete instructions on how to build, install and setup lotus, please visit [https://lotus.filecoin.io](https://lotus.filecoin.io/lotus/install/prerequisites/#supported-platforms). Basic build instructions can be found further down in this readme.
## Reporting a Vulnerability
Please send an email to [email protected]. See our [security policy](SECURITY.md) for more details.
## Related packages
These repos are independent and reusable modules, but are tightly integrated into Lotus to make up a fully featured Filecoin implementation:
- [go-fil-markets](https://github.com/filecoin-project/go-fil-markets) which has its own [kanban work tracker available here](https://app.zenhub.com/workspaces/markets-shared-components-5daa144a7046a60001c6e253/board)
- [builtin-actors](https://github.com/filecoin-project/builtin-actors)
## Contributing
We welcome contributions to Lotus! Please see our [Contributing Guide](CONTRIBUTING.md) for more details on how to get started.
## Basic Build Instructions
**System-specific Software Dependencies**:
Building Lotus requires some system dependencies, usually provided by your distribution.
Ubuntu/Debian:
```
sudo apt install mesa-opencl-icd ocl-icd-opencl-dev gcc git bzr jq pkg-config curl clang build-essential hwloc libhwloc-dev wget -y && sudo apt upgrade -y
```
Fedora:
```
sudo dnf -y install gcc make git bzr jq pkgconfig mesa-libOpenCL mesa-libOpenCL-devel opencl-headers ocl-icd ocl-icd-devel clang llvm wget hwloc hwloc-devel
```
For other distributions you can find the required dependencies [here.](https://lotus.filecoin.io/lotus/install/prerequisites/#supported-platforms) For instructions specific to macOS, you can find them [here.](https://lotus.filecoin.io/lotus/install/macos/)
#### Go
To build Lotus, you need a working installation of [Go 1.22.7 or higher](https://golang.org/dl/):
```bash
wget -c https://golang.org/dl/go1.22.7.linux-amd64.tar.gz -O - | sudo tar -xz -C /usr/local
```
**TIP:**
You'll need to add `/usr/local/go/bin` to your path. For most Linux distributions you can run something like:
```shell
echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.bashrc && source ~/.bashrc
```
See the [official Golang installation instructions](https://golang.org/doc/install) if you get stuck.
### Build and install Lotus
Once all the dependencies are installed, you can build and install the Lotus suite (`lotus`, `lotus-miner`, and `lotus-worker`).
1. Clone the repository:
```sh
git clone https://github.com/filecoin-project/lotus.git
cd lotus/
```
Note: The default branch `master` is the dev branch where the latest new features, bug fixes and improvement are in. However, if you want to run lotus on Filecoin mainnet and want to run a production-ready lotus, get the [latest release](https://github.com/filecoin-project/lotus/blob/master/LOTUS_RELEASE_FLOW.md#why-is-the-releases-branch-deprecated-and-what-are-alternatives).
2. To join mainnet, checkout the [latest release](https://github.com/filecoin-project/lotus/blob/master/LOTUS_RELEASE_FLOW.md#why-is-the-releases-branch-deprecated-and-what-are-alternatives).
If you are changing networks from a previous Lotus installation or there has been a network reset, read the [Switch networks guide](https://lotus.filecoin.io/lotus/manage/switch-networks/) before proceeding.
For networks other than mainnet, look up the current branch or tag/commit for the network you want to join in the [Filecoin networks dashboard](https://network.filecoin.io), then build Lotus for your specific network below.
```sh
git checkout
# For example:
git checkout # tag for a release
```
Currently, the latest code on the _master_ branch corresponds to mainnet.
3. If you are in China, see "[Lotus: tips when running in China](https://lotus.filecoin.io/lotus/configure/nodes-in-china/)".
4. This build instruction uses the prebuilt proofs binaries. If you want to build the proof binaries from source check the [complete instructions](https://lotus.filecoin.io/lotus/install/prerequisites/). Note, if you are building the proof binaries from source, [installing rustup](https://lotus.filecoin.io/lotus/install/linux/#rustup) is also needed.
5. Build and install Lotus:
```sh
make clean all #mainnet
# Or to join a testnet or devnet:
make clean calibnet # Calibration with min 32GiB sectors
sudo make install
```
This will put `lotus`, `lotus-miner` and `lotus-worker` in `/usr/local/bin`.
`lotus` will use the `$HOME/.lotus` folder by default for storage (configuration, chain data, wallets, etc). See [advanced options](https://lotus.filecoin.io/lotus/configure/defaults/#environment-variables) for information on how to customize the Lotus folder.
6. You should now have Lotus installed. You can now [start the Lotus daemon and sync the chain](https://lotus.filecoin.io/lotus/install/linux/#start-the-lotus-daemon-and-sync-the-chain).
7. (Optional) Follow the [Setting Up Prometheus and Grafana](https://github.com/filecoin-project/lotus/tree/master/metrics/README.md) guide for detailed instructions on setting up a working monitoring system running against a local running lotus node.
