## Issue Addressed Related PR: https://github.com/sigp/lighthouse/pull/2137#issuecomment-754712492 The Fork is required for VC to perform signing. Currently, it is not guaranteed that the Fork has been obtained at the point of the signing as the Fork is obtained at after ForkService starts. We will see the [error](https://github.com/sigp/lighthouse/blob/851a4dca3c5a514455006589b1a756a8a994258a/validator_client/src/validator_store.rs#L127) if VC could not perform the signing due to the timing issue. > Unable to get Fork for signing ## Proposed Changes Obtain the Fork on `init_from_beacon_node` to fix the timing issue.
