Lighthouse
As of Lighthouse 3.3.0, the required parameters to make it work with Otterscan are:
lighthouse beacon \
--http \
--http-address "0.0.0.0" \
[--http-port <REST-API-port-number> \]
--http-allow-origin '*' \
--genesis-backfill \
[--disable-backfill-rate-limiting \]
[<other CLI arguments>]
--http-portis optional, by default it binds to:5052.--genesis-backfillis required in order to backfill slot data back to the genesis. If you don't specify that parameter and use checkpoint sync, only slot info after the checkpoint will be available.--disable-backfill-rate-limitingis optional, but if your node is used exclusively for Otterscan you'll probably want to enable it in order to speed up backfilling during the first sync.
