Today, more enterprises seek to set up private networks based on the XDC Network codebase. Whilst the process may seem daunting, knowing the steps to follow simplifies the process. As such, we’ve decided to give you a helping hand. Through this step-by-step guide, you’ll learn how to set up a private network on the XDC Network codebase. Note: This article walks you through the step-by-step setup of a XinFin private network with three masternodes (or network nodes). However, you can set up a private network with up to 5000 Nodes. Setting Up Private Blockchain Network Using XDC Network Codebase #1. Install Golang Download and install  Golang via these steps: i) Download the Go installer for , , or . Windows Linux Mac ii) Install Go on your computer system by following the specified steps, and you’re set up. For more information, refer to the . GO installation page #2. Set Environment Variables i) set GOROOT=$HOME/usr/local/go ii) set GOPATH=$HOME/go #3. Prepare XinFin Network Client Software Download the source code and build here. Run the commands: i) git clone https://github.com/XinFinOrg/XDPoSChain 
ii) git checkout v1.4.4
iii) make all #4. Customize Genesis Block Using the Puppeth Tool Run Puppeth command and answer questions about your private chain as follows: ./Puppeth i) Set chain name as XDPoS ii) Enter 2 to configure new genesis iii) Enter 3 to select XDPoS - delegated-proof-of-stake consensus iv) Set blocktime (default 2 seconds) v) Set a reward for each epoch vi) Set addresses to be initial masternodes vii) Enter the signers address. viii) Set the number of blocks of each epoch (default 900). (Note: If you would like to customize the epoch number, update the code here: common/constants.go:14 EpocBlockRandomize = 900) ix) Set gap (That is: How many blocks are needed to prepare a new masternodes set before checkpoint?) The suggested gap = 5 x) Enter the foundation address in which you hold the private key xi) Enter accounts with which you control private keys to unlock the MultiSig wallet xii) Enter how many Foundation MultiSignWallet require to confirm tx default=2 xiii) Enter the accounts that are allowed to confirm in Team MultiSignWallet xv) Enter the number of Team MultiSignWallet  that are required for confirming tx in MultisignWallet (default=2) xvi) Enter swap wallet address for fund 55 million XDC xvii) Enter the address which needs to be prefunded xviii) Enter the network ID xix) Export the genesis file  by: Selecting 2 to manage existing genesis. Selecting 2  to export genesis configuration Enter genesis filename---XDPOS.json xx) Press Control(CtrL) + C to exit. #5. Setup Bootnode i) Initialize bootnode key by entering the command: ./bootnode -genkey bootnode.key ii) Then start bootnode  with the command: ./bootnode -nodekey ./bootnode.key iii) Copy bootnode information shown: self=enode://c1a13b173d61097ba03c68346c0c761f75095efabe170a55cec427bca83af3c81529b5e6d599c3d594761ea1fac96d291471c805045db385c4c734bc979f63bd@[::]:30301 #6. Start the Masternode Follow the following steps to start the  masternode: i). Clone the Local DPoS Setup repository from: https://github.com/XinFinOrg/Local_DPoS_Setup ii). Replace the genesis file with yours. iii). Enter the bootnode key. iv). Edit the run.sh file by changing the network id and replacing the enode which was generated earlier. v). Enter the private key of the 3 masternode in the .env file, the masternode, and signers private key which was mentioned in the genesis file. vi). Start your masternode with the command : ./bash run.sh To help you understand flags in the run.sh file, here are several explanations. i). --- The log level ranges from 1 to 5. And, in this case, we're using 4 for debug messages Verbosity ii). ---That’s the path to your data directory created above. Datadir iii). ---That’s the path to your account's Keystore created above. Keystore iv). ---That’s your full node's name. Identity v). ---That’s your account's password. Password vi). ---This is XinFin’s  testnet network ID. Networkid vii) ---Your enterprise's full node's listening port (default to 30303) Port viii). -- , -- , -- , -- ---Your full-node will accept RPC requests at 8545 TCP. rpc, rpccorsdomain rpcaddr rpcport rpcvhosts ix). , , , ---Your full-node will accept Websocket requests at 8546 TCP. ws --wsaddr --wsport --wsorigins x). --- It implies that your full-node wants to register to be a candidate for masternode selection. Mine xi). ---That’s the minimal gas price to accept for mining a transaction. Gasprice xii). --- Target gas limit sets the artificial target gas floor for the blocks to mine (default: 4712388) Targetgaslimit xiii). --- Bootnode information helps in the discovery of other nodes in the network Bootnode xv). --- That’s blockchain’s  garbage collection mode ("full", "archive") Gcmode And, to see all flags usages, use the command: XDC  - -  help #7.  Check Your Private Chain To check whether your chain passes the first checkpoint, follow the following steps. i). Connect rpc eth.getBlock(0) eth.getBlock(1) ii) Verify Checkpoints. iii) Wait for 30 minutes to see if your chain passes the first checkpoint. Useful Tools to adopt: Some tools you can use to run different functions of the private blockchain network include:** ** i). XDCPay This extension helps access XDC's XDPoS enabled distributed applications or "Dapps"  within your browser. With the extension, you inject  XDC's XDPoS web3 API into every website's javascript context, helping Dapps read from the blockchain. ii) XDC Remix With the web browser-based integrated development environment, you can write, compile, deploy, and run Solidity-based smart contracts on the XDC network. ** For technical support, let’s connect via XDC’s Social media communities on__ __, , and ** Slack Twitter Discord.
