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 1.23.6 or higher](https://golang.org/dl/): ```bash wget -c https://golang.org/dl/go1.23.6.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 <tag_or_branch> # For example: git checkout <vX.X.X> # 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. ## License Dual-licensed under [MIT](https://github.com/filecoin-project/lotus/blob/master/LICENSE-MIT) + [Apache 2.0](https://github.com/filecoin-project/lotus/blob/master/LICENSE-APACHE) ", Assign "at most 3 tags" to the expected json: {"id":"9640","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
