     5  // within the network, so we can potentially raise a slashing challenge against the origin, should
     6  // we discover that this message is evidence of a protocol violation.
     7  // TODO: this struct does not have its final form. We only retain the ID of the node where the message
     8  // originated. However, this will not allow us to prove to somebody else that `OriginID` really sent
     9  // this message, as we could have tempered with the message and then erroneously accuse `OriginID`
    10  // of a protocol violation. In the mature protocol, `OriginID` will be replaced by an inspector object
    11  // (generated by the networking layer) that allows us to generate a cryptographic proof of who sent the message.
