Excuse my ignorance but, What do you mean with timestamp " isn't enough any

TIMESTAMP records down to the microsecond (us - the 'u' is supposed to
emulate the Greek letter mu), and with a fast processor it is possible
to commit a pair of transactions in the same microsecond. If TIMESTAMP
resolved nanoseconds (ns) then that 'uniqueness' would be restored for
another few generations of processors :-)
