Brief description
This tutorial is used for the construction of any BitShares ( bitshares) chain, such as BAR, Gongxinbao and other copycat chains built through BitShares source code modification. The environment built in this article is a private environment, which is convenient for testing and development. The system is best used Ubuntu, and CentOSother dependencies may need to be installed.
Download program
Go githubto download the compiled program, or you can download the source code yourself and compile it according to the documentation, but the configuration required is very high (8G memory), otherwise the compilation will fail, and the compilation will take several hours.
BTS：https://github.com/bitshares/bitshares-core/releases
BAR：https://github.com/bar-chain/bar-core
I download the compiled binary program directly here
wget https://github.com/bitshares/bitshares-core/releases/download/3.3.2/bitshares-core-3.3.2-linux-amd64-bin.tar.bz2
Unzip
tar -xjf bitshares-core-3.3.2-linux-amd64-bin.tar.bz2
Get two application files
- witness_node: node program
- cli_wallet: Wallet command line program
Create genesis data file
If you are synchronizing public chain data, just skip this step
mkdir genesis
cd genesis
vi genesis.json
Copy and save the configuration information below

Configuration file
After performing the previous operation, a datadirectory will be generated in the current directory , and the block and configuration files will be generated in the directory. We need to modify some configurations
cd data
vi config.ini
The configuration that needs to be modified is as follows
# 找到这一个配置，将值修改为true，这个配置是开启挖矿生成区块，主链的话不需要打开
enable-stale-production = true
# 在文件最后加入下面的配置
p2p-endpoint = 0.0.0.0:11010

Start and stop nodes
The start command is a bit long, in order to facilitate the start and stop, we have made a good start and stop script
vi start_witness.sh
# 将下面的脚本保存
#!/bin/bash
nohup ./witness_node --data-dir data --seed-nodes "[]" >> witness.log 2>&1 &
vi stop_witness.sh
# 将下面的脚本保存

./stop_witness.sh
Stop and start the wallet
To start the wallet, you need to specify RPCthe httpport and websocketport, chain ID, and wallet file. It should be noted that the node must be started before it can be started, otherwise an error will be reported
./cli_wallet --wallet-file my-wallet.json --chain-id ced68e68d7e41258f6a2e71643e41c690edae19dbed8c5f525a0f5c74d322fa9 --server-rpc-endpoint ws://127.0.0.1:11011 -H 127.0.0.1:11012

You can see the command line that will enter the wallet. This command line can be used to create wallets, transfer funds, etc., press Ctrl+Cto exit
In order to facilitate the start and stop, we can also make scripts to start and stop the wallet
