So
today,
myself,
we
will
not
be
focused,
of
course,
on
what
blockchain
is
how
it
works,
and-
and
definitely
I
want
to
give
you
a
view-
what
we
see
with
our
customers
across
europe-
middle
east
africa
and
then
take
you
to
some
of
the
customer
cases
which
some
of
them
fit
perfectly
fine,
with
the
use
cases
that
were
just
shared
and
then
we'll
go
in
as
well
with
some
department
solutions
and
then
we'll
go
into
the
blockchain
platform.
The
hyperledger
part
of
that
how
it
all
works
together.
A
A
All
the
slides
will
be
made
available
as
well
as
the
recording.
So
please
stay
with
me
if
you
may
go
too
fast,
it's
all
available
after
the
recording
first
thing,
I
think
I
would
like
to
to
to
position
as
well
is
that
people
have
been
talking,
of
course,
about
blockchain
for
a
longer
time
of
dlts,
just
with
ledger
technology
for
a
longer
time.
What
we
can
see
now
is
actually
it's
it's
gaining
ground.
A
When
I
was
talking
about
this
three
years
ago,
we
were
very
much
about
trying
to
see
where
it
would
actually
be
sticky,
which
use
cases
would
make
sense
and
which
would
wouldn't
make
sense.
Today
we
are
at
the
stage
that
we
can
see.
This
has
been
more
or
less
crystal
crystalled
out,
and
there
are
definitely
areas
where
blockchain
is
making
waves,
and
we
also
see-
I
think,
that's
good
as
well
for
this
this.
A
The
dlt
front-
runner
such
I
think,
is
also
good
if
you're
investing
in
your
skills
in
hyperledger
fabric
that
you
can
see,
that's
where
the
majority
of
the
implementation
are
taking
place
and
all
in
all
what
we
do
see.
Of
course,
there
are
different
areas,
but
the
the
areas
where
we
see
most
of
the
traction
is
actually
in
the
transportation,
logistics,
so
supply
chain
as
such
and
one
of
our
customers-
and
this
is,
as
was
mentioned
in
the
the
consortium
blockchains,
where
people
work
together.
A
Actually,
competition
works
together,
I'll
come
back
to
this
case
later,
but
it
gives
you
an
id
where
there
actually
is
a
very
much
a
driver
for
joint
working,
because
everybody
benefits
second
thing
we'll
go
into
that
as
well.
Of
course,
the
financial
sector,
not
so
much
the
cryptocurrency
sector,
I
do
see.
Of
course
we
do
have
discussions
on
the
central
currencies,
but
I've
talked
from
enterprise
blockchain,
but
much
talking
about
different
different,
the
in
the
in
the
finance
sector,
and
thirdly,
is
actually
the
traceability
and
traceability,
often
with
a
sustainability
element.
A
A
few
cases
here
and
we'll
touch
one
of
them,
which
is
actually
in
in
the
fall
for
space.
So
that's
like
the
kind
of
the
the
big
ones
that
that
drive
a
lot
of
the
blockchain
projects.
If
we
look
at
the
projects
we've
done
over
the
last
three
years,
we
can
actually
define
five
areas
track
and
trades,
as
mentioned
the
protected
commodities,
and
this
is,
I
would
say-
probably
I
won't
say
it's
the
most
simple
use
case,
but
it's
the
most.
A
It's
probably
the
the
default
use
case
where
you
try
to
track
an
element.
Whether
this
is
a
mineral
that
needs
to
be
changed
into
a
methyl
into
a
in
a
semi
product
into
a
finished
product.
That,
of
course,
is
kind
of
a
straightforward,
but
when
we
look
for
supply
chain
collaboration
a
little
bit
more
complex,
where
we're
talking
about
people
working
together
document
management,
all
this
kind
of
stuff,
I
think
that
that's
that's
where
we
see
a
lot
of
attraction.
A
The
custodianship,
where
it's
about
who
owns
what
who
has
which
right
the
e-voting
was
mentioned.
Certification
was
mentioned,
covert,
19.
I
think
that's
in
that
area.
It
comes
down
with
a
lot
more
things
about
around
identity
management
and
then
more
in
the
financial
financial
settlement,
trade
finance,
how
to
do
how
to
actually
smooth
the
relationships
across
the
trade,
helping
with
finance
structures
as
well
inter-company
transfers-
and
this
could
be
financial.
This
could
be
like
between
banks,
but
also
this
could
be
settlement,
and
I
have
an
example
with
ge
actually
can
show
as
well.
A
So
to
give
you
a
view
on
some
of
the
cases,
these
are
cases
which
actually
are
public
cases
and
I'll
go
in
some
of
them
in
especially
the
ones
in
bold
are
live
so
real
life
cases.
They
do
run
settlements,
they
do
run
transactions
on
a
blockchain
integrated
with
the
backend
systems.
Some
others
are
have
passed.
What
I
call
the
poc
stage,
so
they're
real
life,
they've
done
the
testing
they've
done
some
scalability,
but
they
may
not
do
it
as
a
live
life
solution.
A
So,
as
I
mentioned
supply
chain,
counterfeit
was
mentioned:
luxury
goods,
sustainability
and
authenticity
go
often
together,
transportation,
training
and
the
the
billing
settlement.
That's
actually
across
the
industry.
I
think
this
makes
those
makes
perfect
sense
if
we
dive
in
particularly
in
the
supplies
or
in
the
financial
services
there
you
can
see
also
a
good
number
of,
and
they,
though,
those
are
more
about
identity
management
for
a
kyc,
know
your
customer
tokenization
as
well
cross-border
transfers
and
insurance
cases.
A
So
that's
where
we
can
see
a
lot
of
attraction
and
government
as
well
often,
the
government
cases
are
around
identity
management.
This
could
be
e-voting.
This
could
be
asylum
seeking
this
could
be
tracking
of
resident
new
residency
or
they
have
to
do
with
a
lot
of
documentation.
So
very
document,
heavy
processes
where
the
government
is
involved
could
be
customs,
could
be
application
for
resident
discipline.
That's
where
we
see
a
lot
of
attractions
and
healthcare
as
mentioned
is
a
is
a
definitely
it's
one,
probably
the
most
complex
area,
but
also
there's
a
good
reward.
A
So,
let's
take,
let
me
take
you
to
some
cases
to
give
you
to
show
you.
This
is
real.
This
is
happening,
and
the
first
case
is
about
olive
oil.
This
is
italian
olive
oil,
I'm
not
familiar
with
living
olive
oil.
I
suppose
there's
also
a
good
industry
for
that
of
some
some
or
some
form
of
natural
oils,
so
I
think
it
may
it
may
apply
as
well.
A
The
idea
is
here
that
this
is
existing
business,
which
already
had
in
place
some
of
the
quality
standards,
but
what
I
wanted
to
do
is
to
more
or
less
to
show
that
they
could
manage
the
whole
track
from
the
starting,
the
farmer
into
the
delivery,
and
this
is
delivery
b2b
into
restaurants,
into
wholesalers
that
they
could
track
it,
but
also
that
they
could
manage
the
workflow
with
that.
So
they
started
to
build
actually
a
system
of
workflow
using
some
part
of
the
the
blockchain,
not
the
full
blockchain.
A
They
started
actually
in
the
middle,
with
a
few
of
their
pressings,
with
their
shippers
with
their
marketing
teams
with
their
brand
management,
and
they
built
a
network
where
they
could
track
from
the
lot.
So
a
lot
of
olaf
being
pressed
into
their
retail
into
the
wholesalers
in
the
u.s
and
mexico
from
italy
to
that
and
to
manage
that
properly.
I
think
that
worked.
It
worked
out
really
fine.
Well,
they
actually
rebuilt
a
bit
of
the
supply
chain
and
they
changed
a
lot
of
the
paperwork
that
they
had
to
do
with
it
from
there.
A
They
expanded
it
actually
and
to
scale
it
back
actually
into
the
farms
and
the
pressings
so
to
make
it
really
distributed
start
with
the
quality
as
well
and
to
the
end
as
well.
They
are
also
extended
to
the
end
users
overall,
building
a
traceability
building
a
brand
and
with
that
as
well,
showing
that
they
can
upheld
their
quality
that
they
already
have
and
can
prove
it
with
a
blockchain
that
what
they
show
is
real.
I
think
that's
a
good
case
of
one
of
the
the
first
ones
we
showed,
and
you
can.
A
You
can
apply
this
to
honey
to
any
of
the
products
where
there
is
a
quality
standard
required
as
well.
There's
something
like
trust
that
people
want
to
trust,
and
eventually
people
will
buy
the
product
because
it
will
they
can
trust
it
and
they
will
they
were.
They
are
inclined
to
buy
even
at
a
higher
price,
because
you
can,
you
can
prove
the
deal
to
statisticity
second
case
a
supply
chain.
A
This
is
the
one
I
mentioned
consortium
very
much
across
started
in
the
apec
region.
It's
very
much
about
handling
documents,
because
the
documents
itself
are
quite
a
quite
a
big
blocking
issue.
In
the
whole,
the
whole
shipping,
and
particularly
this,
was
started
with
dangerous
goods,
so
you're
talking
about
goods
that
need
a
lot
of
paperwork,
customs
checks,
etc.
So
they
decided
to
bring
together
a
few
shippers
and
a
few
porters
all
together,
and
this
was
actually
built
by
one
of
our
partners-
cargo,
smart
and
they
built
the
solution
for
this
debut.
A
To
the
end,
delivery
is
managed
on
the
blockchain
visible
made
available
on
the
blockchain,
and
particularly,
of
course,
the
the
documentation
and
what
they
managed
to
do
is
actually
work
together
with
a
lot
of
those
different
shippers
and
competitors
to
bring
to
come
together
as
one
network
and
actually
this
network
together,
ships
around
35
to
40
percent
of
all
worldwide
shipments,
and
then
that
started
with
the
process
of
dangerous
goods
to
to
to
to
cut
things
short.
The
key
thing
is
what
they
did.
A
What
they
found
out
is
actually
they
could
take
down
the
time
it
takes
for
the
documents
to
be
written,
shared
signed
off
by
65
by
using
a
digital
digitized
version
of
the
document
available
through
a
distributed
ledger.
So
this
is
a
very
good
example
of
distributed
ledger
where
people
have
access
and
also
a
permissioned
ledger,
where
those
people
only
have
access
to
what
they
can
see,
or
they
should
be
able
to
see.
I
think
a
very
good
example
of
a
permissioned
high
pleasure,
fabric-based
blockchain.
Actually
it's
and
it
is
across
the
asia-pacific.
A
A
Another
one
I
mentioned
was
ge,
and
this
is
an
example
of
the
one
of
the
third
things,
the
four
things
which
is
actually
settlements,
and
this
is
about
settling
between
different
participants.
So
this
is
a
kind
of
this
you
could
say
is
a
private
blockchain,
where
different
organizations
of
ge
have
to
cross
charge
each
other
for
service
they
have,
and
actually
I
had
a
system
in
place
for
years
already
to
set
this
settlement.
You
can
imagine
with
the
size
of
a
ge.
This
could
also
be
different
companies.
A
But
of
course,
if
you
do
this
right,
maybe
you
do
it
wrong.
It
will
straightaway
have
an
impact
in
your
bookkeeping.
So
to
do
this
right,
it's
very
important,
but
it
takes
a
lot
of
processes,
a
lot
of
people,
so
what
g
has
done
is
actually
to
say:
hey
where
we
do.
This
cross
charging
invoice
settle
settlements,
invoice
validation
on
the
on
a
department
level.
A
We
use
the
blockchainx
to
settle
this
instantaneously
and
in
that,
instead
of
having
a
end
of
the
month,
closing
we
can
do
actually
an
end
of
the
day
or
even
an
immediate
closing.
It's
a
very
good
example
of
how
to
to
use
blockchain,
also
in
a
private
environment,
to
to
create
mass
efficiencies,
and
that,
as
well,
is
interesting
as
well
as
oracle,
see
that
we
can
see
very
much
public
permission
offerings
consortium
offerings
as
all
private
offerings
that
all
make
sense.
A
If
you
find
the
right
use
case,
for
it
then
coming
to
some
of
the
probably
closer
to
home.
So
this
is
actually
one
of
our
customers
in
in
jordan,
jordan,
alleybank
and
what
they've
done?
They
are.
Actually,
they
spin
off
kind
of
a
fintech
themselves,
which
is
ali
fintech,
and
they
built
a
part
of
the
rebuild
actually
part
of
the
onboarding
onboarding
process.
So
onboarding
itself
is
quite
cumbersome
and
what
happened
they
were
thinking
about?
A
This
is
when
kovit
hit
hit
the
road
and
hit
jordan
as
well
so
from
the
start
of
this
was
absolutely
a
a
success
because
they
could
offer
as
their
bank
for
people
to
be
at
home
and
be
able
to
open
up
bank
accounts
with
their
bank
just
using
some
microsoft
technology
for
some
facial
recognition
and
handwriting
and
oracle
technology
to
do
all
the
back
end
where
the
blockchain
sits,
which
actually
looks
into
that
all
stuff
are
done
in
an
auditable
way.
So
this
is
another
element
of
blockchain.
A
Blockchain
gives
you
the
immutability,
so
it
gives
you
the
auditability
of
opportunities
and
that's
what
they've
done,
bringing
blockchain
into
the
onboarding
process
and
interesting
as
well.
They've
done
is
they've,
taken
it
further
and
they're,
now
expanding
to
business
partners
outside
the
banking
sector
that
actually
going
to
make
use
of
the
same
system
for
kind
of
a
nationwide
identification
system
for
onboarding.
So
you
can
imagine
if
it's
telcos
or
utilities
etc.
A
They
can
make
use
of
this
as
as
such
and
a
last
customer
in
the
space
is
actually
a
ministry
in
as
well
in
the
in
the
region,
actually
using
it
for
sharing
privacy
data
for
residencies.
Again,
this
is
done
actually
on
a
fully
in-house
on-premise
world
between
different
ministries,
to
share
information.
You
can
see,
there's
a
broad
area
where
people
could
use
it.
A
This
would
be
by
the
way
a
good
example,
of
course,
discussion
between
centralized
and
decentless
information,
a
government
with
centralized
controls,
but
using
it
to
decentralize
decentralized
data
across
different
constituencies,
different
ministries
which
all
have
their
different
different
requests
for.
Sharing
your
data
as
such
any
one,
which
is
probably
from
a
totally
different
space,
is
actually
pompeii
where
we
worked
with
them.
A
Actually,
the
pompeii
island
park
to
set
up
a
system
covert
19
system
to
make
sure
that
when
people
are
in
there,
they
can
check
how
many
people
are
there,
they
can
get
feedback
from
who
is
where
whatever
and
actually
this
there's
a
good
control
on
the
the
crowds?
There's
a
lot
of
technology
used.
Actually
in
this
because
you're
talking
about
experience,
you're
talking
about
all
kind
of
stuff,
you
need
to
settle,
but
one
part
of
it
is
the
blockchain
part.
A
So
that's
a
great
example
where
you
can
see
that
blockchain
at
the
end
of
the
day
may
not
be
the
the
key
technology,
but
it's
technology
delivers
real
good
value
in
situations
like
covert
19,
to
make
things
really
immutable
and
checkable
and
there's
something
which
is
live,
so
you
can
download
the
the
pompeii
app
and
then
actually,
at
the
back
end,
it
will
run
blockchain
to
everything
you
do
and
visit
over.
There
is
then
being
recorded.
A
These
were
customers
very
quickly,
go
as
well
to
some
of
what
we
call
the
actually.
These
were
end
customers,
but
where
we
see
the
massive
growth
and
also,
I
think
that
hopefully
is
well
interesting
for
a
lot
of
people
in
the
audience.
Here
is
if
you
would
like
to
develop
your
own
solution,
maybe
for
your
market.
So
if
you're
a
partner
or
an
isv
to
develop
some
solutions,
so
as
oracle
blockchain
platform,
you
can
build
your
own
solution
with
that.
A
As
a
customer,
oracle
has
built
a
few
solutions
ourselves,
but
also
we
have
a
great
partner
network
which
builds
solutions
on
top
of
our
technology
and
if
I
start
with
the
ones
that
we've
built
ourselves
a
lot
around,
but
one
of
them
actually
is
some
of
them
are
done
by
our
technology
hub,
and
I
think
they
just
came
around
here.
We
talked
about,
for
example,
the
education
credentials.
I
think
that's
a
key
one
that
we've
built
as
oracle
and
that
we
can
share
as
well.
A
If
you
have
a
situation
where
we
can
share
and
we
can
help
to
build
the
prototype
with
that
other
ones,
for
example
in
the
medical
sector,
for
skew
records
to
use
the
element
of
blockchain
who
can
see
what,
in
what
stage
of
any
part
of
the
process
supply
chain
tracking
as
such
cross-border
transfers,
one
of
our
customers
and
also
invoice
reconciliation.
So
we
have
pieces
that
we
can
share
as
well
as
other
cool
that
can
be
reused
to
prototype.
A
Some
of
those
cases
as
such,
but
I
think
more
important-
is
that
we
have
a
a
good
number
of
partners
and
listed
here
are
partners
who
all
use
oracle's
blockchain
technology,
a
lot
of
them.
They
have
hyperledger
knowledge,
and
then
they
looked
if
oracle
could
be
a
good
technology
for
them
and
they
have
been
building
solutions
on
top
of
our
solution,
which
is
running
on
hyperledger
fabric
and
they
build
it
for
specific
use
cases
vertical
horizontal
industry
use
cases
as
such.
A
Let
me
take
you
to
a
few
just
to
show
what
exactly
is
kind
of
the
power
you
can.
You
can
bring
if
you
have
those
built,
so
one
of
them
is
circular
from
the
uk,
but
actually
there
a
lot
of
the
best
started
in
africa
in
the
mining
sector,
in
rwanda,
they're
now
expanding
it
and
actually
attracting
from
actually
mining
into
refinery
from
refinery
into
the
semi
products
etc,
and
this
was
all,
of
course,
I
think
that's
used
there.
A
But
with
that,
of
course,
that's
only
part
of
the
the
chain,
and
that
is
done
with
as
well.
Ait
solutions,
ai
solutions,
iot
solutions
to
bring
it
all
together
and
to
create
as
much
data
points
that
you
need
to
start
the
blockchain
with
a
proper
input,
because
that's
the
whole
thing
somewhere
has
changed
between
the
physical
world
and
the
digital
world.
That's
what
you
need
to
do
properly
so
using
facial
recognition,
geofencing
all
this
kind
of
stuff
to
make
them
once
done
the
blockchain,
then
you
can
push
it
through.
A
Interestingly,
what
actually
surplus
done
is
they've
worked
also,
we
work
with
them
with
the
automotive
industry,
particularly
for
electrical
vehicles,
and
with
that
we
found
out
actually
it's
great
to
see
that
mining,
of
course,
could
be
the
source
of
a
lot
of
distrust.
You
would
like
to
track
it,
but
actually
what
we
try
to
do
as
well.
A
The
key
thing
is
here:
they're
using
it
for
recycling
of
cobalt
for
electrical
vehicles,
we're
talking
about
mica
and
other
other
communities.
I
think
it's
a
great
case.
This
is
something
that's
valid
for
everyone,
and
one
of
the
other
cases
that
we're
working
with
them
is
actually
carbon
footprint.
Tracking
and
that's.
This
is
carbon
footprint
tracking
carbon
footprint
tracking
across
the
manufacturing
space.
So
you
can.
A
You
can
actually
record
on
the
blockchain
how
much
carbon
footprints
carbon
is
is
being
produced
whilst,
for
example,
producing
a
car
and
that
becomes
more
and
more
important
as
well
when
we're
starting
about
positioning
positioning,
sustainable
products
as
such
another
part.
Another
part
of
us
is
actually
from
slovenia
and
they've
built
a
solution
for
payments
in
the
milk
sector.
A
Farmers
bring
milk
quotas
etc,
and
how
to
settle
this
across
the
board,
something
as
well
very,
which
is
actually
supported
by
the
eu,
but
I
think
it's
interesting
as
well
to
see
that
we're
mixing
data
and
blockchain
together
and
then
payments
to
make
a
secure
system
because
often
blockchains
are
in
itself
are
pretty
easy.
If
you
look
at
the
blockchain,
it
makes
it
more
interesting
when
blockchain
can
deliver
additional
value
in
a
system
of
different
participants
where
there
may
be
some
trust.
A
Maybe
it's
a
lot
of
processes
that
need
to
be
settled,
then
the
blockchain
really
creates
a
lot
of
value,
and
the
interesting
year
is
what
they've
done
as
well.
Dave
they've
bring
together
the
brought
together
actually
erp
systems
which
need
to
settle
a
lot
of
the
stuff
and
they
need
to
be.
This
need
to
be
settled
with
erp
systems
on
the
back
end,
but
also
do
you
settle
with
payment
systems?
A
What
they
try
to
do
is
also
say:
well,
we
don't
want
oracle's
blockchain,
which
is
highlighted
fabric,
to
run
all
the
logic.
It
will
logic
what
it
will
do.
Actually
it
will
build
the
network
and
it
will
execute
some
of
the
payment
calculations,
but
some
of
the
other
calculations,
for
example.
How
much
do
you
pay?
How
much
is
a
liter
of
milk
worth?
What
are
the
the
the
kind
of
the
parameters
for
the
milk
industry
they've
put
in
a
knowledge
graph
system,
so
the
knowledge
graph
system
works
together
with
the
blockchain
and
those
together
create.
A
Then
what
is
actually
is
the
final
price
for
the
milk.
That's
delivered
at
a
certain
date
time
and
then
make
sure
that
the
payment
is
settled
in
a
completely
transparent
way.
I
think
that's
a
great
solution
as
well,
where
both
farmers
and
milk
factories
and
distributors
all
can
see
what's
their
part
and
how
they,
how
they
make
money,
and
I
think
the
last
one
probably
is
e-voting
one
of
our
cust.
This
is
actually
one
of
um's
dave
built
an
e-voting
system,
for,
I
would
say,
probably
local
government.
So
this
is
talking
about
certain
propositions.
A
That
is
not
about
actually
voting
for
a
person
or
for
a
the
ballot.
It's
more
voting
for
decision
making
and
they've
brought
it
all
together
to
make
it
easier
to
create
it,
but
also
to
make
sure
that
the
identities
are
right,
that
people
can
use
it
twice
that
you
can,
for
example,
have
a
way
called
family
voting.
The
people
vote
for
you,
whilst
you're
not
casting
your
own
vote,
etc.
So
to
really
build
the
solution,
great
solution
again
bringing
different
technologies
together.
So
it's
identity
management
from
this
case
the
belgium
government.
A
It's
me
using
oracle
technology
to
set
some
of
the
back
end,
but
also
they're,
using
other
technologies
like
rocket
chat,
youtube
actually
to
to
create
a
complete
system.
Again,
I
think
that's
that's
the
the
the
beauty
of
it
bringing
blockchain
into
existing
technologies
and
making
it
much
more
resilient,
such
and
the
last
one
actually
is
where
we
work
together.
A
Covert
19
was
mentioned
where
we
worked
together,
actually
with
ibm
and
microsoft,
to
build
a
global
network
where
data
is
shared
and
researchers
can
look
into
the
data
share
the
data
as
such
and
create
it
no
further
do.
I
hope
I
gave
you
some
cases
that
real-life
cases
give
you
ideas
and
I'm
gonna
quickly
move
over
to
the
blockchain
product
and
hand
over
the
ends
in
a
few
a
few
minutes.
A
So
actually
this
all.
What
we've
done
is
done
over
the
last
three
years
and
we've
done
that
with
oracle
technology.
Based
on
what
called
oracle's
blockchain
platform
oracle's
blockchain
platform
is
hyperledger
based
we'll
come
to
that,
how
it
all
works
together,
and
actually
we
have
two
versions
and
yes,
we'll
go
into
more
detail.
We
have
a
cloud
version
and
a
on-prem
version,
so
this
is
actually
our
flagship
product
based
on
hyperledger
fabric.
As
such.
A
What
we
also
do
have
we
have
a
specific
solution,
which
is
called
intelligent,
track
and
trace,
which
is
only
about
tracking
trace
for
the
supply
chain
market,
and
this
is
something
for
example,
which
could
be
used
in
serialization
or
exactly
in
the
distribution
of
vaccine.
That's
particularly
where
it's
it's
focused
on
that
also
runs.
Action
on
blockchain
platform
is
also
hyperledger
fabric
based,
you
might
come
across
a
fourth
notion,
which
is
called
oracle
database
blockchain
tables.
I
just
spent
one
minute
on
it
to
make
sure
that
we
position
it
well.
A
A
They
made
it
possible
to
use
the
same
immutability
capabilities
and
the
auditing
and
certification
capabilities
as
a
blockchain
as
a
dispute,
but
not
with
the
distributed
ledger,
but
with
a
central
ledger.
So
it's
not
a
central.
It's
a
centralized
solution,
a
database
where
we've
added
blockchain
features
to
make
the
database
even
more
secure,
such
so.
In
some
cases
where
we
may
think
where
people
say
well,
we
like
the
immutability
or
irreversibility
of
blockchain.
A
A
We
want
to
make
sure
it
can
integrate
with
rest
of
the
world
and
we'll
touch
on
based
on
that,
but
that's
actually
oracle's
product
strategy,
permission
blockchain,
because
that
makes
sense
for
our
enterprise
world
integratable
as
well
enterprise
ready.
Otherwise,
it
will
not
will
not
be
sticky
and
just
recently,
actually,
we've
done
a
new
release
in
that
new
release.
Actually,
we
a
few
key
features.
I
think
which
I
would
like
to
highlight
is
that
what
we
now
can
do
is
we
can
make
the
blockchain
actually
distribute
across
different
data.
A
Centers
really
distribute
across
the
globe
easy
scale
up
scale
out,
but
also
important
as
well.
We've
changed
from
the
kafka
protocol
to
the
rav
protocol,
the
latest
hyperledger,
and
that
gives
a
good
opportunity
to
actually
to
make
it
much
more
resilient
altogether
and
give
much
higher
higher
availability.
A
C
Thank
you
for
the
presentation.
It's
been
very,
very
informative.
Just
for
the
sake
of
timing,
I
would
like
to
conclude
this
by
four
o'clock
or
something
libyan
time,
so
we
have
half
an
hour
with
mr
saladin
regarding
the
walkthrough
and
we
will
have
a
q
a
session
at
the
end.
So,
mr
jens,
please
try
to
keep
the
time
into
15
minutes.
Please.
B
Let's
check
the
presentation
vote
here
we
go,
or
can
you
see
my
powerpoint
yeah?
Wonderful?
So
that's
all
about
me.
If
you
want
more
connect
with
me
via
linkedin
or
send
me
an
email,
what
I
would
like
to
talk
about
a
little
bit,
how
we
came
to
to
blockchain
in
oracle
and
yoast
always
showed
what
we
call
our
four
step
approach.
B
B
B
Those
missing
features
that
we
have
identified
in
discussion
with
our
customers
to
the
open
source
hybrid
fabric,
but
not
go
that
way
down
to
break
compatibility
to
alter
the
the
open
source
code
so
that
you
have
to
go
with
oracle
once
you
make
your
decision
and
can't
go
back
or
can't
go
into
the
hybrid
environment
where
you
have
an
open
source
application
where
you
have
an
oracle
branded
version
of
hyperelectric
fabric.
So
we
try
to
be
very
careful.
B
We
focused
on
adding
all
those
extensions
to
the
core
open
source
hybrid
fabric
without
breaking
any
kind
of
of
compatibility,
so
you're
still
able
to
join
a
hyperelectric
fabric-based
blockchain
network
with
an
oracle-provided
blockchain
instance
you're,
not
breaking
the
network
compatibility.
You
can
still
participate
in
channels.
You
can
still
run
the
same
chain
code
as
if
you
would
do
it
with
the
open
source,
hybrid
traffic,
but
still
from
an
enterprise
point
of
view.
Our
customers
get
more
or
gain
more
flexibility.
They
gain
more
reliability
around
how
this
service
is
being
provided.
B
You
will
see
much
more
of
that
in
the
in
the
live
demonstration,
of
course.
So
all
in
all,
we
were
able
to
enhance
our
political
fabric,
make
it
better.
You
might
say,
by
adding
features
within
the
distributed,
ledger
technology,
and
we
are
part
of
the
hyperledger
organization,
so
we
are
playing
giving
back
what
we've
done
to
the
open
source
and
we
also
added
some
features
based
on
the
hyperledger
fabric
service
that
we
are
offering
on
top
of
the
oracle
cloud
infrastructure
solution.
So
on
both
areas,
we
we
added,
for
example,
a
rest
proxy
interface.
B
We
added
the
management
operations
console
we
tuned
or
we
scaled
up
the
the
lecture
database
by
replacing
the
couchdb
with
a
berkeley
db,
which
has
a
much
better
performance
for
electric
theories.
We
added
external
services
what
we
call
a
rich
history
database
that
you
can
do
analytics
on
all
the
data
that
you
have
stored
on
your
lecture,
for
example,
and,
of
course,
all
the
underlying
operations.
B
Manageability
capabilities
have
been
improved
by
running
it
on
the
autocloud
infrastructure,
whereas
running
it
on
your
own
data
center,
on
your
on
your
docker
or
on
your
docker
network,
or
in
a
third-party
cloud
providers.
Data
center
recently,
with
a
step
to
our
last
generation
release
of
our
oracle
blockchain,
offering
we
also
added
built
into
the
service
the
capability
of
resilience,
high
availability
architecture
out
of
the
box
by
spinning
up
the
service,
you
can
decide
where
and
what
data
center
it
should
be.
B
What
should
you
back
up
the
failover
data
centers
immediately,
the
the
various
hypernational
fabric,
nodes
and
peers
will
be
distributed
evenly
across
those
availability
data
centers,
so
that
you
always
can
guarantee
that
even
one
available
deficit
is
going
down.
You
still
have
two
others
up
and
running,
providing
all
the
necessary
features
and
functionalities.
B
We
added
capabilities
for
our
enterprise
customers
to
scale
in
and
scale
out
particular
resources,
but
less
on
the
infrastructure
level,
adding
more
cpus,
more
memory,
more
power
to
your
installation,
but
also
on
the
hyperlithofabric
level,
by
scaling
out
in
terms
of
number
of
peers
scaling
out.
The
number
of
certified
authorities
scaling
out
in
terms
of
storage
that
the
ledger
database
is
associated
to
so
a
lot
of
improvements
that
are
very,
very
difficult
to
gain.
B
Yeah,
you
see
all
that
so
step
number
three.
Now
we
have
done
the
improvements
now.
The
question
was:
how
should
we
bring
this
to
our
customers
and
everyone
is
moving
into
the
cloud
also
a
couple
of
years
ago,
we
decided
why
not
offer
this
as
a
cloud-based
service
customers
can
subscribe
to
having
the
capability
to
select.
B
They
would
like
to
start
to
have
electro
fabric-based
blockchain
network
that
would
like
to
join
an
existing
network
with
a
hybrid
effect,
based
instance,
so
give
them
the
ability
to
spin
up
an
instance
based
on
the
open
source
application
fabric,
with
all
the
benefits
that
I've
mentioned
earlier.
It
includes
inside
your
cloud
infrastructure
everything
you
need
to
do.
B
Compatibility
compatibility
here
to
join
with
other
hyperledger
fabric
networks
and
existing
or
creating
new
blockchain
network,
and
the
same
goes
not
only
for
the
cloud
version,
but
also
for
the
100
code,
compatible
enterprise,
on-premise
version
that
you
can
take
and
deploy
in
your
own
data
center.
For
example.
If
you
are
not
allowed
or
don't
want
to
subscribe
to
an
organ
cloud
infrastructure
data
center,
that
is
the
on-prem
version.
B
It's
a
virtualized
environment
that
you
can
download
from
oracle.
You
can
test
it
out
immediately
and
it
can
be
deployed
in
on
on
certain
weatherization
engines,
whether
they
run
in
your
data
center
on
your
local
machine,
without
in
even
in
a
cusp
in
a
cloud
data
center
from
azure
or
aws,
and
you
can
have
all
the
benefits
that
we've
built
on
top
of
hyperledger
fabric,
also
in
an
on-premise
environment.
If
you
don't
want
to
or
can't
subscribe
to
a
cloud
service.
B
B
You
have
capabilities
in
kind
of
architecture.
You
can
create
private
deployment
completely
based
on
on-premise
edition.
You
can
build
a
cloud
service
deployment
by
adding
high
flash
fabric
open
source
running
in
someone's
data
center
and
someone's
cloud
service
to
your
existing
blockchain
network.
Together
with
your
oracle
cloud-based
hyperledger
fabric
offering
or
you
can
have
a
hybrid
network
where
some
participants
are
going
off
on
premise.
Other
participants
are
living
in
the
cloud,
but
you
still
have
a
working
blockchain
network
based
on
hyperledger
fabric
available.
B
This
skill
leads
us
to
the
the
last
building
block
again
from
the
enterprise
perspective
from
our
customers
perspective.
All
this
is
nice
to
have.
It
is
laying
the
groundwork
for
participating
in
the
blockchain
network,
but
it
does
not
give
you
as
much
as
how
the
heck
can
I
create
my.
Can
I
integrate
my
business
processes?
How
can
I
can
integrate
my
services
as
participants
into
a
blockchain
network?
Do
I
have
to
do
this
from
scratch?
Do
we
have
any
cooking
receipts
available
for
me
and
again
here
we
thought
about
okay.
B
Why
not
provide
a
certain
amount
of
pre-integrated
capabilities
and
services
alongside
our
blockchain,
offering
so
that
our
customers
doesn't
have
to
start
from
scratch.
Our
partners
doesn't
have
to
start
off
from
a
blank
white
sheet
of
paper,
but
still
are
able
to
immediately
connect
the
business
service
into
into
the
blockchain
network,
whether
this
are
by
the
orc
integration
cloud,
whether
it's
on
a
pure
nava
geology,
node.js,
client,
sdks
or
a
restaurant,
an
application,
the
api
ipi
development
integration.
B
That
really
is
based
on
the
on
the
business
process
of
the
customers,
enterprise
infrastructure,
where
you
would
like
to
integrate
a
blockchain
into
I'll.
Just
give
you
an
example-
and
this
definitely
does
not
speak
as
a
reference
architecture,
but
it
could
be.
You
have
your
oracle
blockchain
instance
that
is
part
of
blockchain
network.
It's
attached
to
the
identity
management,
so
you
can
assign
users
and
approach
to
this.
You
need
some
kind
of
overlay,
so
you
visualize,
what's
going
on
visualize
your
business
processes,
what
they're
doing
with
the
blockchain
network
receiving
submitting
transactions
endorsements?
B
Contrary
to
a
point-to-point
integration
which
of
course,
is
possible
with
the
blockchain
platform
from
oracle.
So
it
could
go
from
easy
to
more
complex,
but
definitely
it
adapts
to
the
enterprise
requirements
to
our
customers
and
partners,
requirements
that
we
have
my
saying
is
always
blockchain
itself
doesn't
make
sense,
but
blockchain
integrated
into
business
process
or
vice
versa.
Business
process
enhanced
with
blockchain
capabilities.
B
We
provide
faster
and
richer
integration
capabilities
as
compared
to
other
hyperlink
fabric
offerings
on
the
market,
and
we
have
a
much
better
administrative
I.t
operations,
integration
which
our
customers
definitely
will
value,
because
this
is
in
the
end,
what
they
would
like
to
ask
for.
How
can
how
can
I
get
this
blockchain
instance,
this
blockchain
network
into
my
overall
ip
applications
into
my
monitoring,
logging
consoles
and
so
on,
and
we
are
still
interoperable
with
existing
hyperledger
fabric-based
blockchain
network
initiatives
that
are
available
on
the
market.
B
We
thought
about
okay,
if
we
can
release
a
burden
of
building
chain
code
of
maintaining
the
development
cycle
of
shane
code
and
introduce
a
tool
that
could
help
our
partners
and
developers
with
that.
We
came
up
with
the
blockchain
builder,
which
is
quite
new,
released
in
november
this
year,
where
you
can
go
from
a
specification
file
which
you
more
or
less
write
in
business
language
no
code,
the
app
builder
will
read
the
specification
file.
B
It
will
interpret
the
definitions
in
the
specification
file
and
then
generate
chain
code
out
of
that
either
node.js
or
in
go,
and
then
it
also
provides
you
a
testing
environment
where
you
can
test
and
make
iterations
make
changes
to
the
shakeone
go
into
testing
cycle
again
up
until.
Finally,
you
are
able
to
deploy
this
generated
chain
code
from
business
language
into
your
blockchain
instance
into
your
channels
into
a
hardware
fabric-based
blockchain
network.
This
is
one
of
the
latest
enhancements
we
we
did
on
top
of
our
solution.
B
It's
available
for
windows,
linux,
mac
os
as
a
command
line
integration
or
what's
even
more
interesting
as
plugin
for
visual
studio
code
editor.
So
you
can
do
in
your
pro
in
your
preferred
editor.
You
can
enhance
and
then
speed
up
your
your
schenko
development
instead
of
doing
everything
from
scratch
on
a
white
piece
of
paper.
By
that
I
would
like
to
hand
over
to
share
it
and
to
start
with
live
demonstration
and
also
some
insights
into
the
application
builder.
Thank
you
very
much.
D
D
D
D
D
D
I
have
to
create
their
own
channels
again
right,
so
I'm
just
describing
the
context
now,
but
I'm
gonna
show
you
exactly
how
this
is
being
done
and
then
take
you
through
through
the
steps
now
for
the
sakes
of
the
time
whenever
you
create
a
blockchain
platform,
or
instance,
it's
gonna
take
around
like
10
to
12
minutes,
so
I
took
the
liberty
to
create
two
of
them.
I'm
gonna
create
one
for
you
now
and,
as
I
go
through
the
demo,
we'll
go
back
and
have
a
look
at
it.
D
D
So
the
thing
is
here
that
this
is
the
primary
instance
and
that's
the
one
who
is
going
to
join
the
instance.
As
you
can
see,
the
role
is
a
participant,
so
I
need
to
have
another
dealer
right,
so
I'm
going
to
create
one
num
and
show
you
how
this
is
easily
can
be
done.
So
I
have
the
button
here
create
blockchain
platform,
I'm
going
to
create
on
that.
D
D
These
are
logical,
isolations,
where
you
can
create
a
certain
instance
that
no
one
has
access
to,
and
you
can
put
some
security
rules
on
top
of
it
and
and
to
provide
to
prevent
access
from
unauthorized
people.
So
for
me
I
have
a
compartment
called
blockchain
meetup
and
then
I'm
gonna
put
a
display
for
for
the
new
instance
of
the
dealer.
I
already
have
the
name
here,
so
that's
the
jewel
dealer.
Then
I'm
gonna
put
some
description
and
then
here
I
have
the
option
to
either
create
a
new
network.
D
Basically,
this
is
if
it's
a
founder
or
I
have
just
to
select,
join
an
existing
network
which
is
a
participant.
So
since
jude
dealer
is
a
competitor
of
sam
dealer
and
both
are
selling
parts
to
detroit
auto.
So
therefore
joe
dealer
will
be
joining
the
detroit
auto
and
therefore
I'm
gonna
select
john
an
existing
network.
Now.
D
Unless
you
are
a
group
of
companies
and
you
are
creating
for
everyone
else
that
are
within
the
companies,
but
you
and
you
want
to
interact
with
each
other.
Then
you
need
one
admin
who
can
do
all
of
that,
then
I
go
to
the
edition
where
I
have
standard
and
enterprise,
so
I'm
going
to
select
standard
here
which
is
going
to
give
you
two
oracle:
processors,
50gb
of
storage
and
two
peers.
Otherwise,
for
the
enterprise
we
have
different
options
depending
on
the
size
of
your
business.
Of
course
you
can
create
multiple
blockchains
and
join
them
together.
D
If
you
need
to
go
beyond
that,
but
for
now
we're
going
to
go
with
the
standard.
So,
as
you
see
what
I
did
here
select
my
compartment
display
name.
Some
description
created
the
platform
role
which
edition
I
need
and
that's
it.
If
I
have
third
party
certificates,
I
need
to
apply,
I
can
just
drag
and
drop.
I
don't
have
one
now.
I
don't
need
it.
D
So
I'm
going
to
create
the
hit
the
create
button
and
what's
going
to
happen
now
is
the
platform
we're
going
to
instantiate
the
jude
dealer
blockchain,
and
this
is
going
to
take
around
10
minutes,
I'm
going
to
leave
it
there
and
then
I'm
going
to
go
and
work
on
those
two,
so
I
already
have
opened
them
here.
So
what
I
have
is
detroit
auto,
which
is
the
founder,
and
I
do
have
sam
dealer,
which
is
the
participant
of
detroit
auto.
They
pretty
much
have
the
same
dashboards
and
and
interface.
D
So
I'm
going
to
focus
on
one
here
initially,
you
would
have
your
own
dashboard,
where
you
can
have
a
summary
of
what's
being
deployed.
We
have
two
channels,
I'm
going
to
create
a
new
one
as
well.
We
have
peers
that
are
the
two
peers.
When
I
created
the
standard
edition
of
this
blockchain
channel,
we
have
two
orders,
which
is
the
the
components
that
are
responsible
for
ordering
the
transactions
and
making
sure
they
are
being
deployed
within
the
the
ledger.
D
I
have
one
smart
contract,
which
is
the
chain
code
and
it
has
different
terminologies
a
program.
It's
a
software.
It's
a
function.
It's
a
smart
contract
at
the
end
of
the
day,
which
is
a
software
deployed
within
the
blockchain
each
one
of
them,
and
they
all
you
know,
just
execute
those
functions
within
the
smart
contract
and
one
participant
which
is
to
my
knowledge
is,
of
course,
the
the
sam
dealer.
Additionally,
I
have
the
health
of
my
blockchain.
D
I
have
the
activities
at
the
channel
level
and
I
have
the
activities
at
the
peer
level
all
within
a
unified
dashboard.
That
gives
you
what
you
need
in
order
to
deploy
the
blockchain
and
managing
it.
Now,
on
top
of
that,
I'm
not
gonna
go
in
details
within
all
of
the
tabs.
What
I
want
to
show
you
is:
when
you
create
the
network,
you
can
easily
have
it
represented.
You
know
each
of
all
the
nodes,
how
they
are
interconnected.
D
So
basically
I
would
have
the
list
here
once
the
jude
instance
is
completed.
I
can
join
it
and
then
it
will
be
part
within
this
network
and
then
I
have
also
all
the
nodes
that
I'm
going
to
interact
with,
let
it
load
for
a
while.
So
here
I
would
have.
I
have
10
nodes.
There
are
part
of
the
detroit
auto
the
main
one,
and
when
I
join
a
participant
it
will
be
listed
here.
D
All
the
information
are
private
between
the
manufacturer
and
the
auto
parts,
but
at
the
same
time
I
can
create
a
channel
between
competitors
if
there
is
something
they
want
to
share
and
come
or
to
in
common,
as
you
have
seen
in
in
the
presentation
shared
by
yust,
some
of
the
competitors
are,
actually
you
know
using
the
blockchain,
because
there's
a
benefit
for
them
from
a
business
point
of
view.
So
all
this
is
possible
within
the
within
the
blockchain.
D
D
D
Let's
say
that
within
sound
there
are
different
departments
that
need
to
communicate
with
the
with
detroit
and
therefore
they
each
have
their
own
separate
channel.
So
that's
the
channel
name.
It
has
to
be
unique,
of
course,
and
then
I
have
to
select
the
the
organization
that
is
going
to
join
this
channel.
So
since
I
only
have
two
now
this
is
sam
dealer
and
then
I
need
to
tell
the
channel
which
peers
in
detroit
will
be
read
and
writing
from
from
within
this
channel.
D
So
I'm
going
to
select
both
of
them
and,
as
you
can
see,
I
have
the
choice
to
select
whether
sam
dealer
is
going
to
be
reader
or
also
writer,
since
I'm
going
to
transact.
Therefore,
I'm
going
to
have
read
reader
and
writer,
then
I'm
going
to
click
submit
hello.
Here.
I
have
a
confirmation
message
that
once
I
created
a
channel,
I
cannot
delete
it.
That's
fine,
I
don't
want
to
delete
it
and
the
channel
will
take
a
little
bit
for
it
to
be
created
and
then
it
will
be
listed.
D
All
right,
so
there
you
go,
and
this
is
the
sam
new
channel
right
now.
Here's
the
thing
about
the
sam
new
channel,
I've
created
it
in
detroit,
but
then
also
and
I've
added
the
peers.
And
now
what
I
need
to
do
is,
I
need,
to
you
know,
add
the
peers,
the
participant
into
this
channel.
So
I
go
to
sam
dealer.
D
And
wait
for
it
to
load
there
you
go.
The
same
new
channel
is
at
the
participant
because
that's
the
blockchain,
they
sync
everything
all
together.
So
what
I'm
going
to
do
now
is
I'm
going
to
join
peers
to
the
channel.
This
tells
the
whole
channel
that
the
peers
in
the
participant
will
be
the
ones
sending
data
to
the
over
the
channel
to
to
the
founder,
so
they're
joining
the
network.
D
And
there
you
go,
I
have
two
peers
now
joined
now.
The
thing
is
the
founder
doesn't
yet
know
that
the
sam
dealer
has
joined
the
channel.
So
what
we
need
to
do
is
we
need
to
export
those
those
participles
nodes
and
the
peers,
and
then,
when
we
export
them,
we
will
tell
the
let
me
just
copy
that
export.
We
will
tell
the
founder
that
actually,
those
two
peers
within
your
participant
are
the
one
who's
going
to
be
sending
your
data.
So
let
me
save
that.
C
D
Click
open
I'm
going
to
import
now,
I'm
going
to
receive
a
certain
message.
This
is
a
warning,
but
this
is
fine,
because
I've
already
done
some
previous
configuration
and
those
periods
already
exist.
I'm
going
to
confirm
because
then
I'm
going
to
replace
the
existing
pieces
with
the
new
information
once
I've
added
them
to
the
to
the
channel
right
and
as
you
can
see
here,
is
the
same
new
channel
being
part
now
of
the
whole
network.
D
So
initially
I
would
have
had,
let's
say
the
sam
channel
and
which
is
being
joined,
and
now
I
have
the
sam
dealer
who
joined
the
sam
channel
initially
and
now.
Additionally,
I
have
added
a
new
channel,
so
now
they
can
actually
communicate
over
that
all
right.
Any
questions
so
far
more
shall
I
proceed.
D
D
I
can
have
multiple
smart
contracts
here,
but
then
this
one,
what
I'm
gonna
do
is
I'm
gonna
now
instantiate
it
over
a
channel.
Now
this
is
the
new
channel
right
sam
channel
is.
I
cannot
click
it
because
I'm
already
done
now,
I'm
going
to
go
to
sam
new
channel,
I'm
going
to
select
the
peers
that
that's
going
to
be
instantiated
upon.
I
have
some
called
the
endorsement
policies.
These
are
which
organizations
we're
going
to
assign
the
transaction
and
and
mind
the
block
and
add
the
transaction
to
to
to
the
ledger.
D
D
Now
this
is
done
there
you
go
and
what
happens
now
is
that
those
two
network
can
now
communicate
over
the
blockchain
and
send
information
for
each
other.
So,
in
order
to
test
this,
what
I'm
going
to
do
is
I'm
going
to
use
the
rest
api
built
in
within
the
blockchain
to
show
you
how
this
is
being
done.
So
give
me
a
second
until
I
get
my
tools,
so
I'm
using
postman
which
allows
me
to
post
data
to
the
blockchain
and,
as
you
have
seen
here,
what
I'm
doing
just
explaining
the
the
process.
D
D
And
we
have
something
called
rest
proxy
right,
so
this
is
the
proxy.
This
is
where
I
can.
This
is
the
url
for
the
rest
api.
Then
I
need
the
endpoint,
so
I
usually
copy
this.
One
that
will
be
will
constitute
the
first
part
and
then
the
endpoints
is
api,
v2
channels,
sam
channel
and
then
or
I
can
use
the
new
channel
or
any
channel
to
have
and
transactions.
D
D
These
are
the
arguments,
so
usually
you
would
have
let's
say
your
smart
contract.
It's
a
function
that
has
input
parameters.
Those
input
parameters
will
go
there
right.
I
can
specify
additional
information
and
I
have
to
specify
the
endorsers.
So
this
I
remember
when
you
created
the
channel,
we
created
two
endorsers
who
are
going
to
sign
the
data
going
into
the
blockchain
right.
So
all
I
have
to
do
now
is
and
the
the
place
where
I
get
this
endorser
is
pretty
much
from
the
same
page.
I
get
the
full
url.
D
It's
actually
here.
So
for
detroit,
that's
the
remote
procedure
and
then
I
just
get
that
part
and
the
same
thing
for
peer
two.
I
can
always
have
one
but
remember
I
have
configured
to
have
signed
by
two
organizations,
so
I
can
select
either
one
now
I'm
gonna
do
is
I'm
gonna
post?
Hopefully
everything
will
go
well.
D
D
D
Okay,
there
you
go
this
is
I
had
to
refresh
to
get
the
transaction,
so
this
is
the
fifth
transaction
which
I
have
just
like
published
and,
as
you
can
see,
this
is
shira3
and
all
the
data
validation
result
is
valid,
etc,
etc.
So
this
is
actually
how
you
can
view
your
your
blogs.
Of
course
you
can
leverage
the
apis
to
do
more
configuration
read
the
list.
You
can
have
integration
tools
that
talk
to
the
blockchain
and
that
would
be,
let's
say,
endpoint
for
digital
assistant,
the
oracle
digital
assistant,
which
is
the
blockchain.
D
If
you
want
to
do
voting
from
a
mobile,
app
or
a
chatbot,
you
can
integrate
it
with
the
blockchain
or
all
sorts
of
things
that
used
and
ian's
have
demonstrated
within
the
use
cases
and
the
architecture
of
the
blockchain
all
right
now.
One
of
the
things
you
need
to
know
as
well
is
the
developer
tools.
Now
I've
used
postman.
I
just
wanted
to
show
you
that
how
we
could
use
the
rest
apis,
how
it's
flexible,
how
you
can
view
that
back
from
the
console,
however,
you
can
always
use.
D
E
E
E
E
E
E
E
You
can
also
choose
the
language
for
which
you'd
like
to
create
the
chain.
Call
app
builder
presently
supports
two
languages,
one
typescript
and
the
other
is
go
presently
marvel's
sample
file
is
supported
for
go,
so
I
will
choose:
go
I'll,
specify
the
marble
as
a
specification
file,
I'll
name
it
as
one
underscore
marble
chain
code.
E
E
I
expanded
the
marble
chain
port
over
here.
There
are
two
important
files,
the
controller
and
the
model.
Let
us
click
on
the
controller
file
in
the
controller
file.
You
can
see
all
the
different
product
methods
and
the
other
methods,
along
with
the
custom
methods
are
created
over
here,
you
can
come
and
you
can
update
the
declaration
for
any
of
the
custom
methods.
E
In
the
third
step,
you
can
modify
the
generated
chain
code,
you
can
put
the
custom
method
definition
and
update
it
in
the
controller
file.
I
have
a
specific
business
logic
for
my
custom
method,
so
I
have
already
written
over
here.
I
just
copy
this
custom
method
and
paste
it
here
in
the
controller
file.
E
E
D
D
The
nodes
I
can
create
the
channel
instantiate
the
chain
code,
install
it
on
a
dude
and
have
it
privately
communicate
with
the
with
the
detroit
auto,
and
then
I
even
can
create
a
private
channel
between
the
the
dealers
and
and
others,
so
they
can
have
their
own
data
shared
over
the
blockchain
within,
as
you
have
seen,
I
have,
I
have
done
any
configuration
I
haven't
done.
I
didn't
open
any
console,
a
command
line
or
or
wrote
some
script.
D
It's
all
few
clicks
here
and
there-
and
this
is
the
the
advantage
of
the
platform
that
we
we
take,
the
the
hyperledger,
for
example.
We
take
the
the
tools,
all
the
components
and
we
package
them
within
the
platform
that
is
more
enterprise-grade,
because
we
have
all
those
connectors.
We
have
the
security
security
on
top
of
oci.
D
We
have
all
this
user
interface
that
allow
you
to
create
the
the
nodes
drawn
networks,
create
the
channels
deploy
and
instantiate
your
smart
contracts
even
develop
just
with
a
few
clicks
within,
within
the
same
same
same
platform,
user
interface
and
tools.
We
take
all
the
complexity,
we
architected
the
blockchain
to
to
work
this
way
and
just
to
help
you
focus
on
what
matters
is
just
like:
creating
those
networks
connecting
them
together
and
then
publish
transactions
over
the
the
ledger.
C
C
C
C
A
Yes,
so
so
what
you
just
respond,
we
do
see,
of
course,
what
you
described
we
could
see
as
well.
Some
of
our
partners
have
done
some
work
actually
using
of
parameters
which
are
then
input
to
a
smart
contract.
I
think
what
shirat
has
showed
chaincode
a
smart
contract
is
quite
key
in
how
you
how
a
transaction
is
being
it
being
executed
on
a
blockchain
network.
The
smart
contracts
to
a
certain
extent
could
be
almost
like
your.
A
You
could
hold
some
formula,
some
checks
in
there,
some
checks
and
balances,
so
you
could
use,
for
example,
a
smart
contract
to
do
kind
of
a
entry
check
and
then
also
execute
it
so
transform
some
information
and
such
though
I
would
warn
not
to
make
the
smart
contacts
too
complex,
because
some
of
the
stuff
you
want
to
do
in
the
on
the
smart
contracts
are
really
have
to
do.
What
would
you
like
to
execute?
A
So
if
you
just
say
I
want
to
do
some
some
basic
checks,
you
could
do
also
outside
the
blockchain
and
then
the
then
you
could
run
it
and
then
the
results
you
could
send
to
the
blockchain
to
the
rest.
Proxy,
if
you
say
well,
I
want
to
do
some
checks
on
quality
controls
and
actually
under
some
parameters.
You
could
exactly
build
that
image
in
the
blockchain,
which
means
that
the
blockchain
acts
almost
like
an
auditor
for
validated
data
onto
the
blockchain.
A
The
reason
that
you
do
that,
then,
is
of
course,
that
you
then
share
the
cleanse
data
with
the
rest
of
the
network,
and
this
is
where
the
channel
comes
down
the
channels
and
the
way
you
set
up
your
network
that
the
data
that
that's
done
on
the
blockchain
is
already
cleaned.
According
to
the
chain
code,
the
agreed
business
logic
and
then
can
be
used
by
the
other
participants
as
clean
cleanse
data
as
such,
so
for
quality
controls.
A
C
C
My
question
is:
when
you
work
on
supply
chain,
and
especially
with
pharmaceuticals,
then
you
need
to
record
the
temperature
values
every
certain
time.
But
what
if
you
work
with
connectionless
environment,
I
mean
when
you
are
inside
the
airplane
or
over
or
in
the
sea,
then
you
don't
have
an
internet
connectivity.
A
B
What
I
would
see
here
more
is
a
side
agreement
with
your
blockchain
business
partners
or
pub
business
partnerships
that
you
have
on
the
blockchain
to
settle
on
those
situations
and
not
put
the
trust
in
the
blockchain
data.
In
terms
of
if
the
data
is
in
the
blockchain,
it
has
to
be
the
accurate
data,
but
if
the
data
is
a
blockchain,
the
person
who
was
the
the
system
who
has
submitted
the
data
as
a
blockchain
is
responsible
for
providing
the
accurate
data.
B
So
the
the
data
inside
the
blockchain
is
just
giving
a
status
and
it
might
be-
and
you
have
to
agree
with
the
business
partners
of
the
status-
is
accurate
because
it
comes
from
live.
Data
of
the
status
is
maybe
questionable
because
it
comes
from
offline
data,
say
you
cannot
submit
data
because
it's
transmitters,
like
fc,
so
you
submit
data
after
the
the
transit
has
reached
a
port
or
harbor,
and
then
you,
you
sync,
the
data
that
has
been
collected.
B
The
question
here
is
not
is
the
data
because
it's
in
the
blockchain
is
accurate,
but
is
the
data
accurate
by
the
person
or
the
institutional,
the
data?
So
it's
still
possible
to
build
a
scenario
like
that.
You
must
just
agree
with
all
the
participants
how
you
treat
data
coming
in
this
blockchain,
based
on
what
kind
of
criteria
they
have
been
generated
from.
That
would
be
my
my
starting
point
for
a
discussion
here.
A
A
Could
it
help
there's
also
the
other
other
part
of
it?
Of
course,
if
you
are
offline
for
a
certain
time
and
you
get
back
on
then
hyper
electric
fabric
has
what
we
call
the
gossip
protocol.
That
makes
sure
that
there's
a
sinking
again
so
that
nodes
that
have
been
offline
for
a
time
will
be
synced
up
and
and
actually
get
even
with
the
rest
of
the
network.
A
C
C
In
that
case,
let's
say
a
temperature,
and
probably
here
the
question
is
just
how
to
ensure
that
this
identity
is
not
tampered
with
and
then
this
iot
device
would
require,
maybe
a
hardware
security
module
that
would
ensure
that
the
identity
is
secure,
and
thus
we
ensure
that
all
this
data
that
was
gathered
and
signed
is
still
also
authentic.
Once
connection
is
is
established
and
all
this
data
can
be
stored
back
on
the
blockchain.
