Quick Start for Beginner

Refer to Download page for binary releases of cpchain.

For ease of reading, we use cpchain to represent all available cpchain versions. The instructions below are demonstrated on Linux.

If you are using Windows platform, all commands below are also viable. Just replace cpchain with cpchain-windows-4.0-386.exe or cpchain-windows-4.0-amd64.exe.

For 32-bit PC user, please select 386 version. And 64-bit PC users should download amd64 version.

For Mac user, please download darwin version. (Darwin forms the core of macOS)


All code starting with a $ is meant to run in your terminal or cmd. Do not copy $, as it is not a part of a command.

Apply for a Wallet

Use the cd command to enter the directory containing cpchain binary file.

For Windows users, use the commands below in cmd.

$ mkdir datadir
$ cpchain-windows-4.0-amd64.exe account new --datadir ./datadir


Change cpchain-windows-4.0-amd64.exe to cpchain-windows-4.0-386.exe if you are using on 32 bit operation system.

For Linux and Mac users, use the commands below in terminal:

$ mkdir datadir
$ ./cpchain account new --datadir ./datadir


If you discard --datadir option, the account file is created under default user directory.

The first command is to generate a keystore file located in datadir/keystore, in which you can find the wallet address. The second command create a new account, and return the wallet address.

Connect to Mainnet


The capitalized VARIABLES requires your modification according to your own settings.

Refer to FAQ if you encounter any problem.

Get Block Mined

This section is for users that are willing to propose new blocks.


Before mining a block, make sure that you the balance in your account is large enough (at least 200,000 cpc).

Windows user the command below. (Here we use amd64 version as demonstration.)

$ cpchain-windows-4.0-amd64.exe run --datadir ./datadir ^
    --unlock WALLET_ADDRESS ^
    --rpcaddr --port 30311 --mine ^
    --rpcapi personal,eth,cpc,admission,net,web3,db,txpool,miner --linenumber

Linux and Mac users please use the following command:

$ ./cpchain run --datadir ./datadir \
    --unlock WALLET_ADDRESS \
    --rpcaddr --port 30311 --mine \
    --rpcapi personal,eth,cpc,admission,net,web3,db,txpool,miner --linenumber


The port 30311 should be opened. Otherwise, other nodes cannot connect you in the P2P network.


If you discard --datadir option, the account file is read from default user directory.


A flag --account WALLET_ADDRESS is required in case your ./datadir directory contains more than one account file.


Flags --rpcaddr and --rpcapi make APIs available in your node. You may discard them if you do not need any API. And make sure the port 8501 is open if you are willing to use APIs.


^ and \ are splitters for long command for Windows and Linux (Mac), respectively. You do not need to type them if you put the command in a single line.

Get Chain Synced

This section is for users that only want to sync with the Mainnet, review or sending transactions.

Windows users can utilize the command below:

$ cpchain-windows-4.0-amd64.exe run --rpcaddr --port 30311

Linux and Mac users please try this command:

$ ./cpchain run --rpcaddr --port 30311

Check Your Status

After you use ./cpchain run command, you have connected to Mainnet. Use the commands below to check your status.

For Linux and Mac users:

$ echo YOUR_PASSWORD > datadir/password
$ ./cpchain campaign status \
--keystore ./datadir/keystore/YOUR_ACCOUNT \
--password ./datadir/password

For Windows users:

$ echo|set /p="YOUR_PASSWORD"> datadir/password
$ cpchain.exe campaign status ^
--keystore ./datadir/keystore/YOUR_ACCOUNT ^
--password ./datadir/password

The first command generates a file containing your password, which are located in datadir/password. The second command is to check your account status given the keystore file as well as the password file you just generate.


If you receive any error message under good network condition, the first thing you need to do is to check if your node version is out-dated.

The upgrade is simple. All you need is to download the latest version from Download page, and replace the old version with the latest one.

You can always use --version flag to check the version.

For Linux and Mac users, use the command as below:

$ ./cpchain --version

Windows users use the following command.

$ cpchain.exe --version

After you upgrade, your node can continue syncing with the chain.
