Goals

Set up a CasperLabs Network with Highway.
Stop a node and restart it. Observe node catching up.
Restart with different round exponents. See the effect on DAG.
Observe effects - CLarity.
Shutdown the network.
We will record the session.

Pre-Requisites

Clone the repository on your machine

git clone https://github.com/CasperLabs/CasperLabs.git

2. Install the latest dev packages from https://repo.casperlabs.io/casperlabs/repo/dev/

# Remove old versions of casperlabs engine, client and node
sudo apt remove casperlabs-client casperlabs-engine-grpc-server casperlabs-node
# Get latest versions of engine, client and node and install the same
curl -O https://repo.casperlabs.io/casperlabs/repo/testing/casperlabs-client_0.14.0_all.deb
curl -O https://repo.casperlabs.io/casperlabs/repo/testing/casperlabs-engine-grpc-server_0.14.0_amd64.deb
curl -O https://repo.casperlabs.io/casperlabs/repo/testing/casperlabs-node_0.14.0_all.deb
sudo apt install ./casperlabs-client_0.14.0_all.deb ./casperlabs-node_0.14.0_all.deb ./casperlabs-engine-grpc-server_0.14.0_amd64.deb
# cross check if all have the same version
casperlabs-node --version

3. Set environmental variables for running Highway

# Export Highway environmental variables
export CL_HIGHWAY_ENABLED=true
export CL_CHAINSPEC_HIGHWAY_BOOKING_DURATION=8minutes
export CL_CHAINSPEC_HIGHWAY_ENTROPY_DURATION=1minute
export CL_CHAINSPEC_HIGHWAY_ERA_DURATION=5minutes
export CL_CHAINSPEC_HIGHWAY_VOTING_PERIOD_DURATION=1minute
# We will provide the Genesis Era Start time
export CL_CHAINSPEC_HIGHWAY_GENESIS_ERA_START=

4. Clean up any leftover state from old runs

5. Create keys and accounts.csv file

6. Start the engine and node

Prerequisites

casperlabs-client

Instructions

You should see the following output:

If you build from source, you will need to add the build directories to your PATH, for example:

7. Observe the network on Explorer
