Truechain Test Network Setup

Installing the system environment

Note: This article operates in a Mac environment.

1. Install go environment (go requires version 1.7 and above)

1. The MAC executes the command brew install go.
   Encountered by the wall problem, you can open the browser https://studygolang.com/dl/golang/go1.10.3.darwin-amd64.pkg download, and then step by step installation.
2. Configure the GOPATH environment variable. Execute the following command in turn:
   Execute CD ~
   Implementation of VI. Bash_profile
   Insert a line of your own project directory address in. Bash_profile Export gopath=/
   Sers/edz/go
   Execute Go ENV
   If the output has the same Gopath value as set above, it is set successfully.

2. Configuring the C Compiler

1. Mac side performs brew install GCC

compiling source files

1. Download Project Source Https://github.com/truechain/truechain-engineering-code
2. Enter the project directory. To compile. Execute command: Make Getrue
3. After the compilation is complete. The path to the Getrue command is the project directory/build/bin/.
4. Add the Getrue path to the system environment variable

Genesis.json

Create your own test network. You first need to create the network's Genesis state, so that all nodes know and agree to this state.
The Genesis state (or Genesis block) is a small JSON file. Such as

Build a test network

Step1. Set up the test directory. For example, test

Step2. Refer to the source code in the Cmd/getrue Genesis.json file, the contents of the file are as follows.

 {  "config": {        "chainId": 10,        "homesteadBlock": 0,        "eip155Block": 0,        "eip158Block": 0    },  "alloc"      : {      "0x970e8128ab834e8eac17ab8e3812f010678cf791" : { "balance" : "90000000000000000000000"},      "0x68f2517b6c597ede0ae7c0559cdd4a84fd08c928" : { "balance" : "10000000000000000000000"}      },  "coinbase"   : "0x0000000000000000000000000000000000000000",  "difficulty" : "0x200",  "extraData"  : "",  "gasLimit"   : "0x2fefd8",  "nonce"      : "0x0000000000000042",  "mixhash"    : "0x0000000000000000000000000000000000000000000000000000000000000000",  "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",  "timestamp"  : "0x00"}

Step3. Create a Genesis block. Execute the following command

Getrue--datadir Test Init Path/to/cmd/getrue/genesis.json

The--datadir is used to specify the directory. When the above command finishes, the directory has more than Getrue and KeyStore two folders. Getrue folder is used to store the relevant data of the chain, KeyStore folder is stored in the chain of user information

Step4. Start the test chain start node. Execute the following command
Getrue--datadir Test--nodiscover console 2>>getrue.log
