Node implementation for the Lux network - a blockchains platform with high throughput, and blazing fast transactions.
Lux is an incredibly lightweight protocol, so the minimum computer requirements are quite modest. Note that as network usage increases, hardware requirements may change.
The minimum recommended hardware specification for nodes connected to Mainnet is:
- CPU: Equivalent of 8 AWS vCPU
- RAM: 16 GiB
- Storage: 1 TiB
- Nodes running for very long periods of time or nodes with custom configurations may observe higher storage requirements.
- OS: Ubuntu 20.04/22.04 or macOS >= 12
- Network: Reliable IPv4 or IPv6 network connection, with an open public port.
If you plan to build Lux Node from source, you will also need the following software:
Clone the Lux Node repository:
git clone [email protected]:luxfi/node.git
cd nodeThis will clone and checkout the master branch.
Build Lux Node by running the build script:
./scripts/build.shThe node binary is now in the build directory. To run:
./build/nodeInstall Lux Node using an apt repository.
If you already have the APT repository added, you do not need to add it again.
To add the repository on Ubuntu, run:
sudo su -
wget -qO - https://downloads.lux.network/node.gpg.key | tee /etc/apt/trusted.gpg.d/node.asc
source /etc/os-release && echo "deb https://downloads.lux.network/apt $UBUNTU_CODENAME main" > /etc/apt/sources.list.d/lux.list
exitAfter adding the APT repository, install node by running:
sudo apt update
sudo apt install nodeDownload the latest build for your operating system and architecture.
The Lux binary to be executed is named node.
Make sure Docker is installed on the machine - so commands like docker run etc. are available.
Building the Docker image of latest node branch can be done by running:
./scripts/build_image.shTo check the built image, run:
docker image lsThe image should be tagged as avaplatform/node:xxxxxxxx, where xxxxxxxx is the shortened commit of the Lux source it was built from. To run the Lux node, run:
docker run -ti -p 9650:9650 -p 9651:9651 avaplatform/node:xxxxxxxx /node/build/nodeTo connect to the Lux Mainnet, run:
./build/nodeYou should see some pretty ASCII art and log messages.
You can use Ctrl+C to kill the node.
To connect to the Fuji Testnet, run:
./build/node --network-id=fujiThe lux-cli is the easiest way to start a local network.
lux network start
lux network statusA node needs to catch up to the latest network state before it can participate in consensus and serve API calls. This process (called bootstrapping) currently takes several days for a new node connected to Mainnet.
A node will not report healthy until it is done bootstrapping.
Improvements that reduce the amount of time it takes to bootstrap are under development.
The bottleneck during bootstrapping is typically database IO. Using a more powerful CPU or increasing the database IOPS on the computer running a node will decrease the amount of time bootstrapping takes.
Lux Node uses multiple tools to generate efficient and boilerplate code.
To regenerate the protobuf go code, run scripts/protobuf_codegen.sh from the root of the repo.
This should only be necessary when upgrading protobuf versions or modifying .proto definition files.
To use this script, you must have buf (v1.31.0), protoc-gen-go (v1.33.0) and protoc-gen-go-grpc (v1.3.0) installed.
To install the buf dependencies:
go install google.golang.org/protobuf/cmd/[email protected]
go install google.golang.org/grpc/cmd/[email protected]If you have not already, you may need to add $GOPATH/bin to your $PATH:
export PATH="$PATH:$(go env GOPATH)/bin"If you extract buf to ~/software/buf/bin, the following should work:
export PATH=$PATH:~/software/buf/bin/:~/go/bin
go get google.golang.org/protobuf/cmd/protoc-gen-go
go get google.golang.org/protobuf/cmd/protoc-gen-go-grpc
scripts/protobuf_codegen.shFor more information, refer to the GRPC Golang Quick Start Guide.
To regenerate the gomock code, run scripts/mock.gen.sh from the root of the repo.
This should only be necessary when modifying exported interfaces or after modifying scripts/mock.mockgen.txt.
Lux Node is first and foremost a client for the Lux network. The versioning of Lux Node follows that of the Lux network.
v0.x.xindicates a development network version.v1.x.xindicates a production network version.vx.[Upgrade].xindicates the number of network upgrades that have occurred.vx.x.[Patch]indicates the number of client upgrades that have occurred since the last network upgrade.
Because Lux Node's version denotes the network version, it is expected that interfaces exported by Lux Node's packages may change in Patch version updates.
APIs exposed when running Lux Node will maintain backwards compatibility, unless the functionality is explicitly deprecated and announced when removed.
Lux Node can run on different platforms, with different support tiers:
- Tier 1: Fully supported by the maintainers, guaranteed to pass all tests including e2e and stress tests.
- Tier 2: Passes all unit and integration tests but not necessarily e2e tests.
- Tier 3: Builds but lightly tested (or not), considered experimental.
- Not supported: May not build and not tested, considered unsafe. To be supported in the future.
The following table lists currently supported platforms and their corresponding Lux Node support tiers:
| Architecture | Operating system | Support tier |
|---|---|---|
| amd64 | Linux | 1 |
| arm64 | Linux | 2 |
| amd64 | Darwin | 2 |
| amd64 | Windows | 3 |
| arm | Linux | Not supported |
| i386 | Linux | Not supported |
| arm64 | Darwin | Not supported |
To officially support a new platform, one must satisfy the following requirements:
| Lux Node continuous integration | Tier 1 | Tier 2 | Tier 3 |
|---|---|---|---|
| Build passes | ✓ | ✓ | ✓ |
| Unit and integration tests pass | ✓ | ✓ | |
| End-to-end and stress tests pass | ✓ |
