Create a simple chain with Byzcoin

steps.sh

# clone the Cothority repo, install bcadmin
mkdir chain
cd chain
git clone https://github.com/dedis/cothority.git
cd cothority/byzcoin/bcadmin
# will install in GOPATH/bin/
go install

# run some conodes
cd ../../conode
 go build --tags test
./run_nodes.sh -d tmp -v 3

# open another shell in the same "conode" folder

# create a chain, add some blocks
bcadmin -config tmp create tmp/public.toml
export BC="tmp/bc-XXXXX.cfg"
bcadmin darc rule --rule "test:test" -id ed25519:aef123

# you can run it multiple times to create blocks
bcadmin -c tmp darc rule --rule "test:test" -id ed25519:aef123 --replace

# you can get the roster in "tmp/public.toml"
# the byzcoin ID (ie. the first block) is print after "bcadmin create"
