Mechanism for handling lost private keys #8
Description
When a trader forgets their public key, we don't want their bonds to be lost. Instead, we want to have a clearing firm be able to reissue their bonds to a different public key so they can resume trading.
I think the best way to do this would be to have a clearing firm invalidate a trader's old public key and transfer all ownership over to a new public key. If we have any bad actor clearing firms, this could be a problem, so we could have each trader associated with a specific clearing firm and have them be the sole administer of their account.
Ex:
Trader A joins the network using Private Key 1 through Clearing Firm 1.
Trader A loses Private Key 1.
Trader A informs Clearing Firm 1 of lost key.
Trader A generates Private Key 2.
Clearing Firm 1 transfers bonds from Public Key 1 to Public Key 2.
