Downloading the Conflux Client

Conflux-rust is a high-performance implementation of the Conflux protocol developed by the foundation with the Rust language. Conflux-rust is a Conflux node that connects to other nodes on the Conflux network and provides an RPC interface that you can use to query and interact with the blockchain. It is also a command-line tool that manages local accounts and conducts RPC interaction with nodes. You can download the released package through any of the ways listed:

Download pre-built binaries​

The release page on the conflux-rust GitHub repository providers pre-built binaries that you can download and run directly. There are two versions for the mainnet and the testnet: the mainnet version is Conflux vx.x.x, while the version for testnet is Conflux vx.x.x-testnet (which has a suffix of testnet). Each program will be provided for Linux, Windows10, and macOS.

On the Release page, each version will have a version update description and Assets that you can download. After selecting the corresponding platform, you can click the link to download the zip package. For example, when unzipping the conflux_linux_v2.0.3.zip file, a run folder that contains node programs, configuration files, and startup scripts will appear. The specific documents include:

➜  run tree
.
├── conflux
├── log.yaml
├── start.bat
├── start.sh
├── hydra.toml
├── pos_config
└── throttling.toml

0 directories, 6 files
  • conflux Node program
  • hydra.toml Mainnet configuration file (If you download the testnet program, the configuration file is called testnet.toml)
  • log.yaml Log configuration file
  • throttling.toml Internet speed flow limit configuration file (used for development and testing)
  • start.sh Linux system startup script
  • start.bat Windows system startup script
  • pos_config Configuration files for the PoS consensus mechanism. Normally you don't need to edit it.

Make sure you only run binaries downloaded from the official Conflux-Chain/conflux-rust GitHub repository.

Then you can use the startup script to start the node. For example, on Linux, you can run the following command to start the node:

./start.sh

Or you can run the following command to start the node:

./conflux --config hydra.toml

Docker​

Conflux provides an official Docker image of conflux-rust. You can use it to quickly start a node. You can start a node within two steps: Download image and Run container.

$ docker pull confluxchain/conflux-rust
$ docker run -p 12537:12537 --rm --name cfx-node confluxchain/conflux-rust

So far, there are three tag lines in the officially released image:

  1. x.x.x
  2. x.x.x-mainnet
  3. x.x.x-testnet

The first type of image will run a private chain node in dev mode by default. The chainId and miner account will be randomly generated. At the same time, 10 genesis accounts will be created (the defult password is 123456), and 1000 CFX will be distributed to each account for developing and testing.

The image with mainnet/testnet suffix tag will activate the nodes of the main network/test network by default. The nodes will start to synchronize data from Epoch 0 through the network. (The process of sychronizing might take a long time, and the transaction sending request won't be processed.)

They all support the use of custom configuration files and data directories through mounting directories. You can check the tutorial at: Conflux-rust docker file on Github

FAQs​

illegal instruction​

If you encounter this error when running the node, you can try to download the compatible version binary from the release page for example conflux_linux_glibc2.27_x64_v2.3.3-compatible.zip , or compile the source code yourself.
