chmod +x loom
mkdir tmpgopath
export GOPATH=`pwd`/tmpgopath
./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
