Instructions for deploying a local a geth + lighthouse blockchain "fixturenet" for development and testing purposes using laconic-stack-orchestrator (the installation of which is covered [here](https://github.com/cerc-io/stack-orchestrator#user-mode)):
## Clone required repositories
```
$ laconic-so --stack fixturenet-eth setup-repositories

## Build the fixturenet-eth containers
```
$ laconic-so --stack fixturenet-eth build-containers
