Prerequisites:

Cloud Server / VPS Recommendations
  • AWS Lightsail - Linux virtual server (1 cpu, 1GB memory, 40GB ssd, 2TB bandwidth)
  • Google Cloud Platform - Compute Engine General purpose (N2)
  • Vultr - Cloud Compute (1 cpu, 1GB memory, 25GB ssd, 1TB bandwidth)
  • Digital Ocean - Droplet (1 cpu, 25GB ssd, 1TB bandwidth)
  • Linode - Shared virtual Instances (1 cpu, 1GB memory, 25GB ssd, 1TB bandwidth)
  • [Others]
  • 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.
Bonding enough DOS tokens to run a node
  • Acquire at least 800,000 DOS tokens, (and optional - acquire several DropBurn token to reduce (up to 30%) the amount of DOS tokens needed to start a node, distribution plan be out later).
  • Replace your node ip address in config.json
  • Node runners currently earn three types of incomes: (Self-bonded) staking rewards, (other delegators') staking reward shares, oracle request processing fees.
Register and setup Infura api key

Run with docker image

  • docker pull dosnetwork/dosnode:v1.0.1-m

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 v1.0.0-m

  • 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.
