Running a local testnet#
To easily start a local testnet you can use the launch_local_testnet.sh
script.
This script allows you to start n amount of nodes and then run several actions
on them through the JSON-RPC API.
Run the local testnet script#
# Run the script, default start 3 nodes
./fluffy/scripts/launch_local_testnet.sh
# Run the script with 16 nodes
./fluffy/scripts/launch_local_testnet.sh -n 16
# See the script help
./fluffy/scripts/launch_local_testnet.sh --help
The nodes will be started and all nodes will use node0 as bootstrap node.
The data-dirs and logs of each node can be found in ./local_testnet_data/.
You can manually start extra nodes that connect to the network by providing any of the running nodes their ENR.
E.g. to manually add a Fluffy node to the local testnet run:
