A method of establishing a chain of relationships, comprising: receiving, by an identity verification platform from a device of a first user, a first request for registration comprising an identification of the first user, identification of an entity, and a relationship between the first user and the entity; verifying, by the identity verification platform responsive to receipt of the first request, the identity of the first user and the relationship between the first user and the entity; verifying, by the identity verification platform, that the entity is legitimate; receiving, by the identity verification platform from the first user, a first invitation for a relationship between a first individual and the entity; transmitting to a device of the first individual, by the identity verification platform responsive to receiving the invitation for the relationship from the device of the first user, a second request for approval of the relationship between the first individual and the entity; receiving, by the identity verification platform from the device of the first individual, approval of the relationship between the first individual and the entity; transmitting, by the identity verification platform to the device of the first user, confirmation of the relationship between the first individual and the entity; creating, by the identity verification platform, a custom badge for display on the entity's website, the custom badge representing the relationship between the first individual and the entity and valid for one or more domains associated with the verified entity; receiving, by the identity verification platform, an identification of a selection by an end user of the custom badge; and responsive to receiving the identification of the selection, rendering, by the identity verification platform, on a domain controlled by the identity verification platform, a verification that the relationship between the first individual and the entity is valid. receiving, by an identity verification platform from a device of a first user, a first request for registration comprising an identification of the first user, identification of an entity, and a relationship between the first user and the entity; verifying, by the identity verification platform responsive to receipt of the first request, the identity of the first user and the relationship between the first user and the entity; verifying, by the identity verification platform, that the entity is legitimate; receiving, by the identity verification platform from the first user, a first invitation for a relationship between a first individual and the entity; transmitting to a device of the first individual, by the identity verification platform responsive to receiving the invitation for the relationship from the device of the first user, a second request for approval of the relationship between the first individual and the entity; receiving, by the identity verification platform from the device of the first individual, approval of the relationship between the first individual and the entity; transmitting, by the identity verification platform to the device of the first user, confirmation of the relationship between the first individual and the entity; creating, by the identity verification platform, a custom badge for display on the entity's website, the custom badge representing the relationship between the first individual and the entity and valid for one or more domains associated with the verified entity; receiving, by the identity verification platform, an identification of a selection by an end user of the custom badge; and responsive to receiving the identification of the selection, rendering, by the identity verification platform, on a domain controlled by the identity verification platform, a verification that the relationship between the first individual and the entity is valid. <EOS>
