Eth2-validator (placeholder name) is a lightweight Ethereum validator.
Deploy a consensus devnet with Viewpoint.
Run the server command to start the Viewpoint server:
$ viewpoint server --name test-altair-1 --num-tranches 2 --altair 1
In another terminal, deploy a Lighthouse validator and two beacon nodes assigned to half of the genesis validator accounts:
$ viewpoint node deploy validator --type lighthouse --tranche 0 --beacon --beacon-count 2
Run Eth2-validator:
$ eth2-validator server --endpoint http://127.0.0.1:<port> --priv-key ./e2e-test-altair-1/tranche_1.txt --log-level debug
where port is the Http port of one of the beacon nodes deployed in the previous step.
