#Download zeknd

The following script can be used to automatically download the stable version of zeknd to the current directory:

curl https://raw.githubusercontent.com/zekndnetwork/zeknd-sdk-documentation/master/scripts/get_zeknd.sh | sh

#Installation

Run these in the same directory as the previous step.

mkdir tmpgopath
export GOPATH=`pwd`/tmpgopath
./zeknd spin weave-blueprint
cd blueprint
export GOPATH=$GOPATH:`pwd`
make deps
make
cd build

../../zeknd init
cp ../genesis.example.json genesis.json

#Run Blockchain

../../zeknd run

#Send transactions

Open a second console and run the following commands:

cd blueprint/build
../../zeknd genkey -k priv_key -a pub_key
./blueprint call create-acct -p priv_key

This will generate a private key and create an account.

Next, let's set a value:

./blueprint call set -v 1 -p priv_key

and read it:

./blueprint call get
