Yes.  But Git clients can't trust the server like that.

The only way to make sure the server didn't send you crap data, or worse 
maliciously altered data, is actually to not transfer any checksum data 
but to recompute and validate the received payload locally.

This being said, you should never have to wait 6 hours for that phase to 
complete.  It is typically a matter of minutes if not seconds.
