DOS Client and Core Libraries

Prerequisites:

Cloud Server / VPS Recommendations

• AWS Lightsail - $5 monthly plan (1 cpu, 1GB memory, 40GB ssd, 2TB bandwidth)
• Vultr - Cloud Compute $5 monthly plan (1 cpu, 1GB memory, 25GB ssd, 1TB bandwidth)
• Digital Ocean - Droplet $5 monthly plan (1 cpu, 25GB ssd, 1TB bandwidth)
• Linode - $5 monthly plan (1 cpu, 1GB memory, 25GB ssd, 1TB bandwidth)
• .

Verified and recommended installation environment

• Ubuntu 18.04 x64 LTS or higher
• An IPv4 address
  • Run $ dig +short myip.opendns.com @resolver1.opendns.com
  • Or get it from cloud server providers. Most vps / cloud server
• With below ports open:
  • udp port 7946
  • tcp port 7946,9501
• It's recommended to generate ssh login key pairs and setup public key authentication instead of using password login for server security and funds safety:
  • Learn how to setup SSH public key authentication on Ubuntu 18.04 and disable password logins.

Acquire testnet ether and testnet tokens

• Acquire testnet ether from rinkeby faucet.
• Acquire 100,000 testnet DOS token, (and optional - acquire several testnet DropBurn token).
• Please fill in this form to request testnet tokens.
• Replace your node ip address in config.json

Register and setup Infura api key

• Register and get Infura api key
• Replace your infura api key in config.json

Run binary from github releases

• Install:

  $ wget https://github.com/DOSNetwork/core/releases/download/v1.0-beta.23/config.json
  $ wget https://github.com/DOSNetwork/core/releases/download/v1.0-beta.23/dos.sh
  $ sudo chmod +x dos.sh
  

• Use a existing keystore (optional):

  $ mkdir vault
  $ cp oldKeyStore vault/
  

• Start:

  $ ./dos.sh start
  

• Check client status :

  $ ./dos.sh status
  

• Stop client :

  $ ./dos.sh stop
  

• Debuging an issue :

  $ ./dos.sh log
  

Building binary from source

• Install Go and setup golang workingspace like below:

  $ sudo apt-get install golang 
  $ sudo apt-get install go-dep 
  $ sudo apt-get install build-essential
  

• Open ~/.bashrc and set $GOPATH and $PATH environmental variables:

  $ vim ~/.bashrc
    export GOPATH=$HOME/go
    export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin
  $ source ~/.bashrc
  

• Download source code:

  $ mkdir -p $GOPATH/src/github.com/DOSNetwork
  $ cd $GOPATH/src/github.com/DOSNetwork && git clone https://github.com/DOSNetwork/core.git
  $ cd core
  $ git checkout v1.0-beta.20
  

• Build:

  • $ make vendor - to prepare dependencies for building
  • $ make - to build release version client

• Run:

  $ ./dos.sh start
  

• Dev tips:

  • $ go fmt ./... to reformat go source code.
  • $ golint to fix style mistakes conflicting with effective go. (golint tool for vim users.)
  • $ make devClient to build develoment version client.
  • $ make updateSubmodule to fetch latest system contracts from repo, instead of making contract modifications locally.
  • $ make gen to generate binding files for system contracts.
  • $ make clean to remove built binaries or unnecessary generated files.
