But
there
are
many
q
band,
a
patterns,
I
think
it's
on
the
screen,,
so
I
think
it
would
be
good.
If
you
could
ask
a
lot
of
questions
with
that
Q&A
button.
Since,
there
is
a
possibility
that
I
will
not
be
able
to
answer
all
the
questions,
I
would
like
to
answer
the
questions
that
many
of
you
are
interested
in
as
much
as
possible.

You
can
understand
that
by
doing
so,
you
can
of
course
reduce
the
consumption
of
storage.
I.
Think
that's
the
point,.
But
the
point
is
that
even
after
discriminating
from
this
local,
I'm
going
to
search
for
a
state
where
I
can
seamlessly
access
the
red-deleted
data
on
top
of
each
other.I
proposed
a
useful
function.
C
I
would
say
that
we
have
developed
such
a
function:
.
Of
course,.
There
are
customers
who
have
such
needs
in
color
locals,,
and
if
you
look
at
the
bar
ticket,,
there
are
many
such
needs
,
and
you
can
see
the
slider
on
the
right.

This

Hyper,

Global,
Forum

is
a
very
interesting
session
where
farmers
who
are
going
to
watch
the

who
is
it?.

you
can
proceed

development
and
improvement
of
this

Attached
to
the
Circle
Romantic
Cycle
Kamasu
The
omission
was
obtained
among
the
strong
contributors.
,
and
I
was
wondering
where
it
would
be
included
in
the
release.

I
was
talking
about
the
total
from
5
years
to
8
infrastructure
operations,,
but
to
be
more
specific,.
The
four
layers
shown
at
the
door
are
unexpectedly
taken
from
the
top.
down.
Look
riff
There
are
8
of
them
here,.
So
let
me
give
you
a
brief
explanation.
First
of
all,.
There
are
8
of
the
pattern
books
on
the
Internet.
B
B
If
I
were
to
ask
what
is
good
about
this,.
Then
yes,
has
decreased
a
bit
recently,,
but
it
is
often
the
case
that
the
first
conversation
with
customers
starts
with
the
question
of
what
the
6000
is.
Sometimes,.
When
I
explained
the
value
of
blockchain
and
linked
it
to
the
customer's
problem,.
There
was
quite
a
bit
of
talk
going
around,.
B
B
The
conversation
will
go
relatively
smoothly.
It's,
going
to
be
a
story
like
"Let's
go,",
but
at
that
time,
the
day
when
we
implement
which
of
the
10
Arnos
I
mentioned
earlier,
well,,
we're
told
to
live,,
but
yeah,
well,
implement
it.
It
's
hard
to
start
from
scratch
without
it,,
so
I'm
creating
a
pattern
book
to
put
out
a
system,
that's
going
to
be
a
head
starter,
and
that's
the
implementation.
Well,.
B

D
D

D

D

That
Ant

become
a
hyper
cold

ir

Ethereum,
isn't
quite
ferocious
I,
don't
often
hear
people
who
pull

but
that

in

And
promote

Liam
for
companies,
Enterprise
Isari,
Marlines
The,
other
day,.
A
collaboration
was
announced,
and
I
feel
that
we
have
a
complementary
relationship
by
creating
common
standards
and
interacting
with
each
other
.
D
D
D
D
D
The
event
story
for
setting
up
such
things
that
can
be
done.
Well,.
It's
a
collaboration.
These
three
are
provided
a
I
want
to
introduce
a
better
service.
Erro,
ses,
So
I
think
it's
a
ducati
lure,,
but
Yutaka-chan's
circumstances
are
correct:
That's,
not
the
case,.
So
for
example,,
when
it's
used
in
production
work,,
it's
necessary
to
prepare
engineers
in-house
first
.
D
D
D
The
base.
It
goes
without
saying
that
if
you
can
get
a
support
service
through
the
cooperation
of
the
support
production
areas
of
each
country's
bases
for
20
hours,,
you
can
feel
safe
when
using
Honman..
We
can
also
do
it,.
So
we
would
like
to
concentrate
on
development,
and
we
can
expect
to
use
it
to
improve
development
efficiency.
D
D
D
D
D
D
D
D
D
D
D
D
There
are
several
projects
that
combine
these
kinds
of
projects,
and
Hitachi
has
its
own
library,
and
there
are
several
such
models,,
but
by
providing
such
combinations,,
it
is
possible
to
achieve
high
reliability
in
a
short
development.
Period..
The
second,
is
to
save
labor
in
the
same
industry
as
block
warfare..
D
D
You
to
do
as
much
as
possible
to
those
voices
of
anxiety.
Scenarios
on
how
to
operate
in
reality,
Well,
based
on
that
,
I
think
it's
necessary
to
expand
support,
functions,
Ahhh
Finally,.
We
provide
an
enterprise
development
environment.
Ethereum
has
a
lot
of
rows
for
6
developers,
For
individuals,
There
are
a
lot
of
things
like
this,
and
it's
a
system
development
by
providing
the
infrastructure.
That
was
the
methodology
when
developing
in
a
team,
while
using
the
tools
that
engineers
are
used
to.
D
D
D
In
terms
of
my
head,,
as
I
mentioned
in
the
solution
section
of
the
organization
I
belong
to
,.
In
addition
to
development
support,,
there
are
projects
with
the
same
name,
such
as
operation
management
and
data
utilization,
and
product
services..
We
have
a
lot
of
research
results
and
solutions,,
and
we
hope
that
by
combining
these
assets
of
the
Hitachi
Group,,
we
will
be
able
to
provide
new
value
to
everyone
in
social
studies
and
problem-solving..
D
D
Well,
I
think
that
kind
of
world
will
come.At
that
time,.
It
will
be
possible
to
use
this
technology
called
Ethereum,,
which
can
be
used
for
both,
and
tomorrow
will
become
like
tomorrow.
,
and
various
services
will
be
developed
in
the
state..
There
are
people
from
different
fields,
and
I
hope.
We
can
open
up
a
new
market
together
with
these
players.
E
E
Thank
you
very
much
for
your
support.The
detailed
specifications
of
this
session
will
be
announced
later
by
the
secretariat,.
So
if
you
have
any
questions,,
please
do
not
hesitate
to
contact
us
after
the
seminar.,
However,
I
hope
you
can
refer
to
it,.
So
what
I'm
going
to
show
you
from
now
on
is
a
god
that
cuts
off
the
distribution
of
God.
E
E
Terms
of
composition,
there
are
4
banks,,
green
banks,
,
red
beings,
,
blue
c,,
no
banks,
d
banks
are
lined,
up.
It's
been
done
s
bar
From
now
on,,
the
bento
that
is
involved
in
the
operation
is
picked
up
by
this
web
server.
Web
app,
and
this
ship
paint
is
transferred
to
it,
and
it
is
configured
to
control
individual
animations,
.,
So,,
originally,
I
would
use
my
smartphone
to
hang
up
the
qr
code,
display
it,
get
off
like
this,
and
receive
it.
However,
today,
due
to
equipment.
E
E
Whether,
it's
done
or
not
is
high
As
for
the
status,.
It's
managed
in
the
public
state
on
the
right
side
of
this
here,
and
it's
transaction
information.
After
cutting
.
We've
created
a
system
that
allows
data
to
be
shared
only
between
the
existing
ones,
and
with
Fabric,.
We've
realized
this
kind
of
configuration
with
channels
.
E
E
E
E
E
E
E
E
A
E
Know,
but
I'd
like
to
continue
with
ing,,
so
I
did
some
netting
before
the
check
transactions
here,,
but
I'll
settle
these
transactions
together
and
finally..
This
is
the
kind
of
settlement
where
you
pay
the
difference,,
and
this
is
done
by
a
centralized
organization
such
as
the
check
clearing
house.
E
After,
calculating
the
amount
of
production
at
each
individual,
bank,
I
think
there
are
banks
that
each
have
their
own
country,
but
I
think
more
about
their
production
functions.
.
If,
you
decide
a
route,.
You
can
define
it
as
a
clock
like
abce,
and
effectively
flow
the
production
function
by
shaving.
The
route.
Netting
is
completed
when
the
deduction
becomes
zero..
Originally,
transactions
between
banks
were
agreed
upon,,
but
it
was
done
at
a
short
time,
but
today,,
it's
not
easy,.
So
it's
convenient
to
use
the
echo
button.
I
want
to
press
this
button
to
start
necking.
E
E
Based
on
that
fan,
big,
based
on
this
kind
of
opinion,,
our
block
battle
team,
discussed
the
difference,
narrowing
it
down
to
a
winning
streak
and
writing
from
this
perspective.
As.
For
the
course
,
did
you
feel
anything
for
the
first
time
this
time,
we
started
with
a
dialogue
about
the
chain
code,
such
as
the
fake
smartphone,
that
you
like
the
features
on
the
apron
mouth,
platform.
I,
think
it's
organized,
is
n't.
It
?
Director
Hideaki
is
a
good
point,.
Isn't
it.
E
?
In
terms
of
authority,,
it
was
mentioned
that
restrictions
such
as
the
use
of
variable-
length,
character,
strings
for
the
time
being
are
quite
characteristic.
According
to
the
design
concept
of
the
eye,
I.
Don't
think
it's
better
to
think
about
the
preliminaries
when
it
comes
to
asking
for
high
expressive
power
in
a
smartphone
in
the
first
place,
.
E
E
E
I'm
back
and
I'm
grateful
to
Fabric
5
Centrize
It's
easy
to
make
the
moon
now
As
for
the
base.
That
was
mentioned,,
the
output
of
the
public
chain
remains,
and
it's
a
good
read,.
But
our
final
conclusion
is
that
it's
hard
to
put
down
the
public
base.
On
top
of
that
,
I
came
to
the
conclusion
that
it
is
important
to
think
about
the
enemies
of
the
elementary
school.
B
B
B
B
's
right,
the
query,,
because
the
lower
possible
data
stores
are
different.
,
I
think
there
will
be
a
little
difference
in
terms
of
what
the
query
is
good
at
and
not
good.
At.
I
think
it's
something
like
the
idea
of
combining
the
capabilities
of
your
company,,
such
as
whether
you
can
improve
the
development
resources.I'll,
give
you
an
exam
le.
