## Issue Addressed Resolves #2069 ## Proposed Changes - Adds a `--doppelganger-detection` flag - Adds a `lighthouse/seen_validators` endpoint, which will make it so the lighthouse VC is not interopable with other client beacon nodes if the `--doppelganger-detection` flag is used, but hopefully this will become standardized. Relevant Eth2 API repo issue: https://github.com/ethereum/eth2.0-APIs/issues/64 - If the `--doppelganger-detection` flag is used, the VC will wait until the beacon node is synced, and then wait an additional 2 epochs. The reason for this is to make sure the beacon node is able to subscribe to the subnets our validators should be attesting on. I think an alternative would be to have the beacon node subscribe to all subnets for 2+ epochs on startup by default. ## Additional Info I'd like to add tests and would appreciate feedback. TODO: handle validators started via the API, potentially make this default behavior Co-authored-by: realbigsean <seananderson33@gmail.com> Co-authored-by: Michael Sproul <michael@sigmaprime.io> Co-authored-by: Paul Hauner <paul@paulhauner.com>
