type ValidatorRole

type ValidatorRole int8

ValidatorRole defines the validator role.

const (
	// RoleUnknown means that the role of the validator cannot be determined.
	RoleUnknown ValidatorRole = iota
	// RoleAttester means that the validator should submit an attestation.
	RoleAttester
	// RoleProposer means that the validator should propose a block.
	RoleProposer
	// RoleAggregator means that the validator should submit an aggregation and proof.
	RoleAggregator
	// RoleSyncCommittee means that the validator should submit a sync committee message.
	RoleSyncCommittee
	// RoleSyncCommitteeAggregator means the valiator should aggregate sync committee messages and submit a sync committee contribution.
	RoleSyncCommitteeAggregator
