1. A network node, comprising: a memory; and one or more processors to: receive a message that is associated with one or more first signatures and one or more second signatures, the one or more first signatures having been validated by a particular node; determine that the particular node is a trusted node, the network node not to validate signatures that have been validated by the trusted node; determine that the one or more first signatures have been validated by the particular node; determine that the one or more second signatures have not been validated by the particular node, the one or more first signatures being different than the one or more second signatures; validate the one or more second signatures and not the one or more first signatures based on determining that the one or more first signatures have been validated by the particular node and that the one or more second signature have not been validated by the particular node; and sign or provide the message, without validating the one or more first signatures and after validating the one or more second signatures, based on determining that the one or more first signatures have been validated by the particular node and that the one or more second signatures have not been validated by the particular node.
