  We study holographic entanglement and information scrambling in de-Sitter
(dS) space in the context of the DS/dS correspondence. We find that our
previously identified non-local entanglement structure of dS vacua can be
extended out of the time-reflection symmetric slice. We extend the geometry to
a two-sided configuration and calculate the zero-time mutual information
between two intervals on different sides when there is a localized shock wave
in the bulk. Interestingly, we find that the information scrambling time
saturates the fast scrambler bound proposed by Sekino and Susskind and that the
shock wave renders a wormhole to be traversable. Furthermore, we calculate a
two-sided out-of-time-ordered correlator (OTOC) in the late time regime and we
see that, before scrambling, it exponentially grows with an exponent whose
value saturates the maximal bound of chaos proposed by Maldacena, Shenker and
Stanford. At the end, we provide an explanation why the exponential growing of
the late-time OTOC with the maximal bound of chaos saturated and the
traversability of the wormhole are simple results of the non-local entanglement
structure and point out that this is a realization of the ER=EPR proposal.
