Key Series Addition

Once a DID is registered, its owner has the option to add more key series with did_add operation. This operation requires another active key series to sign and verify its HTTP request. In the did_add request, the client must specify the SHA-256 hash of the first public key in the new series must be given.
A new key series cannot be used to sign and verify its own addition.
