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

OSX: brew install mercurial bzr

./run.sh -h

*Running Wallet

./run.sh

Then open http://127.0.0.1:6402 in a browser.

Golang environment 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 go1.6
gvm use go1.6 --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 go1.6 >/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 github.com/skycoin/skycoin

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

Dependencies

go get github.com/robfig/glock
glock sync github.com/skycoin/skycoin
go get ./cmd/skycoin

To update dependencies

glock save github.com/skycoin/skycoin/cmd/skycoin

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/
