export PROTOBUF_VERSION=3.5.1
curl -OL https://github.com/google/protobuf/releases/download/v${PROTOBUF_VERSION}/protoc-${PROTOBUF_VERSION}-linux-x86_64.zip
sudo unzip protoc-${PROTOBUF_VERSION}-linux-x86_64.zip -d /usr/local
sudo chmod +x /usr/local/bin/protoc

Installation
curl -OL https://downloads.loomx.io/loom/linux/stable/loom
chmod +x loom
export GOPATH=~/gopath
export PATH=$GOPATH/bin:$PATH
./loom spin weave-blueprint
cd blueprint
export GOPATH=$GOPATH:`pwd`
make deps
make
cd build
../../loom init
cp ../genesis.example.json genesis.json
Run Blockchain
../../loom run
Send transactions
Open a second console and run the following commands:
cd blueprint/build
../../loom 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
