skycoin

Skycoin is a next-generation cryptocurrency.

Skycoin improves on Bitcoin in too many ways to be addressed here.

Skycoin is small part of OP Redecentralize and OP Darknet Plan.

Installation

• For detailed installation instructions, see Installing Skycoin*

For OSX:

1. Install homebrew, if you don't have it yet

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Install the latest version of golang

$ brew install go

3. Setup $GOPATH variable, add it to ~/.bash_profile (or bashrc). After editing, open a new tab Add to bashrc or bash_profile

$ export GOPATH=/Users/<username>/go
$ export PATH=$PATH:$GOPATH/bin

4. Install Mercurial and Bazaar

$ brew install mercurial bzr

5. Fetch the latest code of skycoin from the github repository

$ go get github.com/skycoin/skycoin

6. Change your current directory to $GOPATH/src/github.com/skycoin/skycoin

$ cd $GOPATH/src/github.com/skycoin/skycoin

7. Running Wallet

$ ./run.sh
OR
# go run ./cmd/skycoin/skycoin.go
For Options
# go run ./cmd/skycoin/skycoin.go --help

For linux:

$ sudo apt-get install curl git mercurial make binutils gcc bzr bison libgmp3-dev screen -y

#Setup Golang

• use gvm
• else download binary and follow instructions

#Golang ENV setup with gvm

In China, use --source=https://github.com/golang/go to bypass firewall when fetching golang source

$ sudo apt-get install bison curl git mercurial make binutils bison gcc build-essential
$ bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)
$ source $HOME/.gvm/scripts/gvm

$ gvm install go1.4 --source=https://github.com/golang/go
$ gvm use go1.4
$ gvm install go1.7
$ gvm use go1.7 --default

If you open up new terminal and the go command is not found then add this to .bashrc . GVM should add this automatically

$ [[ -s "$HOME/.gvm/scripts/gvm" ]] && source "$HOME/.gvm/scripts/gvm"
$ gvm use go1.7 >/dev/null

The skycoin repo must be in $GOPATH, under src/github.com/skycoin. Otherwise golang programs cannot import the libraries.

#pull skycoin repo into the gopath
#note: puts the skycoin folder in $GOPATH/src/github.com/skycoin/skycoin
go get -v github.com/skycoin/skycoin/...

#create symlink of the repo
$ cd $HOME
$ ln -s $GOPATH/src/github.com/skycoin/skycoin skycoin

Dependencies

Dependencies are managed with gvt.

To install gvt:

$ go get -u github.com/FiloSottile/gvt

gvt vendors all dependencies into the repo.

If you change the dependencies, you should update them as needed with gvt fetch, gvt update, gvt delete, etc.

Refer to the gvt documentation or gvt help for further instructions.

Running A Skycoin Node

$ cd skycoin
$ screen
$ go run ./cmd/skycoin/skycoin.go
#then ctrl+A then D to exit screen
#screen -x to reattach screen

##Todo

Use gvm package set, so repo does not need to be symlinked. Does this have a default option?

$ gvm pkgset create skycoin
$ gvm pkgset use skycoin
$ git clone https://github.com/skycoin/skycoin
$ cd skycoin
$ go install

##Cross Compilation

Install Gox:

$ go get github.com/mitchellh/gox

Compile:

$ gox --help
$ gox [options] cmd/skycoin/

• one way latency
• two way latency (append), latency between packet and ack
• service handler (ability to append services to meshnet)
• uploading bandwidth, latency measurements over time
• end-to-end route instrumentation
