It's
always
been
a
topic
of
discussion,,
but
recently
I've
been
thinking
that
the
platform
for
doing
digital
tonersometion
in
teams
is
also
a
technology.
.
I
think
that
even
if
only
one
company
does
dx
,,
it
will
be
effective
in
its
own
way,,
but
I
think
it
is
the
blockchain
that
allows
multiple
companies
to
do.
It.
C
So,
um,
well,
with
blockchain,.
There
are
multiple
distributed,
ranger
schools,
,
and
each
of
them
supports
each
other
in
this
way,.
So
it's
said
that
it
has
extremely
high
availability.
Well,.
Today's
theme
is
,
for
example,.
If
that
particular
Endo
from
the
Civil
Engineering
Department
goes
down,,
even
if
the
other
endorsers
are
alive,
for
example,.
If
there
is
no
endorsement
of
the
downed
towel
in
the
endorsement
policy,,
the
transaction
will
come
first.
If
it
becomes
a
setting
that
you
can't
proceed.
To,
it's
a
bit.
Bad,
isn't.
C
C
I'm
sure
you've
all
seen
this
party
often,
but
Linux,
is
on
top
of
the
server,
and
in
this
case,
Org
beats
8x
and
ends.
So,.
If
the
Mafia
school
is
working,,
the
orders
will
be
working.,
Station,
section:
I'm,
going
to
be
a
client
of
Hyper
Leather
Fabric,,
but
I
have
this
kind
of
shape
,.
So,
of
course,
I
can
confirm
the
operation
of
that
fabric.
Of
course,,
with
this,
for
example,.
If
the
big
dollar
x,
one
falls,,
it
will
stop
very
quickly,.
So
if
the
linux
server
fails,,
this
will
also
stop
immediately.
Well,.
C
C
It
means
that
the
store's
concentration
can
be
output,
all
the
time,,
so
the
availability
has
increased
somewhat,,
but
even
with
this,,
as
I
said
at
the
beginning,,
one
server
went
down.
Or,
for
example,.
The
Org-kai
would
stop
working
at
all,
or,
if
all
x
were
to
go
bankrupt,.
The
order
ringer
would
stop,,
so
the
service
as
a
whole
would
stop
first
.
That's
fine,,
but
if
it's
an
actual
service,,
it's
going
to
be
a
waste
of
money.
C
C
C
C
C
C
C
Center
The
data
center
on
the
left
actually
has
two
levels
of
concentration,,
1
and
2..
That
means
that
the
power
is
at
the
injury,
level,
well,,
the
concentration
is
backed
up
by
the
older
brother
once
and
moves,,
and
the
data
center
looks
exactly
like
the
data.
Center.
I
thought
that
even
if
things
went
wrong,,
it
would
continue
to
operate
at
the
neighboring
data
center,
and.
C
C
A
data
center
called
the
so-called
Abera
bt
zone,,
but
it's
terrible
because
it's
near
the
port
in
terms
of
network,
and
the
water
level
is
set
to
0.
Is
it
okay
or
something?,
In
fact,.
If
you
don't
put
out
something
that
is
connected
like
this,
in
the
case
of
IBM,
for
example,
in
the
Kanto
region,,
there
are
3
radar
centers
during
the
bt
zone,
such
as
rain.
C
If,
you
connect
this
with
two
clusters,.
You
can
create
this
structure,,
but
for
example,,
this
area
of
Saitama,
and
Kanagawa
is
a
very
wide-area
disaster
that
can
be
wiped
out
in
one
go,,
such
as
freez
ng.
Well,
in
such
a
case,.
Even
this
is
not
enough
,.
So
if
you
want
to
prepare
a
window
for
the
number
of
attacks
and
disasters,,
you
have
no
choice
but
to
make
a
backup
of
that
data.
And.
C
When
something
like
this
happens,,
we
set
up
an
umbilical
cord
site
in
an
area
that
hasn't
been
affected
by
the
disaster,
and
restore
it
from
a
backup.
Of
course,.
We
have
to
escape
from
that
attack
disaster,.
So
it's
an
object.
Storage,
that's
common
in
the
cloud,!
So
if
you
buy
the
data
there,,
it's
okay.
C
C
C
C
Well,,
this
is
proof
of
that,,
but
on
the
left
side,
there's
one
farm
road,
and
there's
one
concentration
of
4
cores
,
and
that's
the
only
concentration,
that's
Kuba
sound,.
So
it's
not
even
a
cluster
pillow
star.
However,.
There
is
only
one
,
and
on
top
of
that,
there
are
0.2
cores
for
aca,,
then
2
pia,,
each
with
0.5,
cores,
and
0.5
for
clients,
for
a
total
of
2.7
cores,
.
C
C
C
C
Are
3
pus
in
the
data
center
at
this
meeting,
right?
It's,
an
honorable
situation
that
the
voices
of
8
1
all
day
are
dancing
above,.
So
here's
a
dog,,
epice
farmers,,
that's
the
first
concentration,
node
1's
server
went
down
outside
that
town,.
So
this
situation,
In
fact,
it's
possible
for
the
hyper
public
to
continue
running
like
this.
C
C
C
C
Would
like
you
to
imagine
something
like
this.
Things
are
called
antiques,,
which
means
they're
going
to
be
peers
,,
so
we're
going
to
relocate
them
to
farm
roads,
2
and
3..
This
kind
of
thing
can
be
done,,
so
this
deployment
surface
and
the
controller.
I
want
to
move
the
pod
in
the
direction
I
want
to
move
it,.
So
it's
a
manager-like
thing
to
do.
C
I'm
sure
there
are
some
people
who
think
this
is
the
first
thing
to
do,.
But
it's
true
that
if
the
January
issue
of
Noudou
went
out
of
business,
pr
and
ca
would
work
well,,
but
then
the
node
that
had
the
same
problem.
In
other
words,.
If
the
rep
ramen
and
the
controller
die,
is
n't
that
bad
in
the
first
place?
That's,
exactly
what
you
said,
and
the
availability
of
this
master
mode
is
extremely
important
for
the
operation
of
Tokuba
trains..
C
C
C
C
C
C
C
C
C
C
C
C
C
C
The
case
of
the
elder
sister's
leader
being
elected
by
the
school,,
it
is
decided
by
majority
vote,,
but
in
the
case
of
grandchildren,
the
majority
is
3
.
So,.
If
there
are
three
remaining,
well,,
if
those
people
all
agree
on
the
name,,
they
can
make
a
decision,.
So
in
that
sense,
the
number
of
child
nodes
is
quite
good..
C
C
Continue.
Well,,
that
raft
will
start
publishing
responses
from
that
xix
2,.
So
these
people,
1
and
2,
will
also
participate
in
that
raft's
cluster
stupidity
,,
but
using
another
data,
replication
protocol
345
to
122,
Well,
I,
like
data,
and
with
this,
that
concentration
learns
to
be
in
an
equilibrium
state.In.
C
C
C
Version
is
the
version
that
arrived
yesterday
that
maintains
backward
complementarity.
It's,
a
certain
version
upgrade
,
and
5
new
versions
will
be
released,
and
it
will
be
announced
on
the
mailing
list
or
in
the
release.
Notes,
,
and
the
fabric
lead
dog
will
give
a
detailed
explanation.
Now,
in
the
case
of
blockchain,.
There
are
so
many
concentrations,,
so
there
is,
of
course,
the
possibility
that
all
versions
of
those
elementary
concentrations
will
not
be
available,.
But
one
thing
I
would
like
to
keep
in
mind.
Is
the
network.
C
C
,,
it
can
be
done
in
a
mode
that
has
the
latest
version,,
but
it
has
the
version
one
generation
earlier.
Of
course,.
What
cannot
be
done
with
sound
can
be
done
in
this
way,
and
controlling
this
is
a
sub-function
called
capability.
That's,
what
I
mean,,
but
by
using
this,,
even
if
a
new
version
is
introduced,,
it's
possible
not
to
enable
the
latest
features
of
that
new
version,.
C
So
the
way
to
do
it
is
to
use
the
latest
version.
And.
It
would
be
best
if
we
could
upload
most
of
them,,
but
even
if
we
don't
understand,
everything,
we'll
have
enough
to
continue
the
service.
When
the
mode
becomes
the
latest
version.
BT
If
you
give
it
up,,
it
will
be
in
the
form
of
completion
of
that
version,
upgrade
.
And.
As
for
that
repair,,
there
is
long
term
support.
Lts
burn,-
and
this
is
going
to
be
good..
Fabric
will
be
committed
to
support
for
more
than
a
year,,
and
it's.
C
C
C
That's
what
I
mean,,
but
there
are
times
when
the
toppo
compatibility
is
not
maintained
with
that
major
version,,
but
even
so,
at
least
for
now,.
We
can
upgrade
the
version
without
stopping
the
service.
,
especially.
It
should
be
noted
that
version
1.4
or
version
82.4
xn
In,
that
major
version
upgrade,.
The
format
of
the
piano
database
has
been
changed.
C
C
C
C
C
C
C
C
Correct
horse
racing
ability
is
still
left
as
it
is
in
1.4.
If.
You
make
horse
racing
bt
demon
at
this
timing,.
The
orderer's
x2
hall
x5
will
crash,
so
well,
with
this,
the
order
will
not
work.
Please,
don't
do
that.
Hey,,
it's
the
same
in
a
loop.
You
upgrade
in
order
up
to
the
big
dollar
x.
5.
This
is
how
it
feels
when
you're
doing
that,
for
example.
So
order,
ringer
It
's
the
point
that
the
bisdrama
will
continue,,
but
in
the
end,
all
points
went
up
by
2.2
points.
C
C
C
C
C
Or,
the
image
of
the
chain
code,,
if
you're
a
Fiaponte,
you're
going
to
delete
everything
around
here
by
mistake.So
next
time,,
just
like
the
owners
earlier,,
the
piano
image
of
the
fabric,
8
From
2.2,
8
I'm,
going
to
do
a
coaster
on
the
peer,.
So
when
I
start
the
peer's
ape
2.2100,,
the
version
of
the
stationary
couch
and
the
bully
db
included.
Gdb
is
also
attached
to
this
peer.
However,
since
I
dropped
that
db
earlier,.
This
version,
2
format
is
specified,,
but
the
data
itself
is
empty,,
isn't
it?.
C
C
C
C
C
C
C
Blockchain
platform
I
mentioned
earlier.
As
I
mentioned
earlier,.
This
Coover
Ladies
uses
Manage
Dog
Hane
on
the
IBM
cloud,
of
course,,
Amazon,,
Microsoft,,
etc.
It
will
be
in
the
form
of
being
able
to
move
naturally
on
top
of
this,,
and
it
will
not
be
the
operation
of
Edo
public,
such
as
giving
transactions,
but
creating
an
organization,,
adding
new
peers,
and
creating
channels.
That's.
What
I'm
talking
about
if
I
create
it,?
But
this
is
how
I
usually
do
it
with
the
cli,,
but
it's
quite
difficult
because
the
operation
is
complicated
and
it's
easy
to
make
mistakes.
C
C
C
C
.
But
Maku
Barepisuka,
that
class
that
can
be
created
with
open
shift,.
That
9,
is
thinking
of
a
cat
that
doesn't
get
caught,
and
that's
what
you're
choosing.
Select
8
data
centers,
and
then
the
density
that
runs
on
them.,
Worker
density
and
sentence
theory,.
But
what
are
the
specs?
In
this
case,?
Would
you
like
to
run
3?
In
this
form,?
We
will
create
a
class
and
Aoko,,
and
on
top
of
this
cluster,
we
will
actually
put
the
Hyperledger
8
public
component,
Piada,,
order,,
etc.
That's
why,.
C
B
C
C
C
C
C
A
C
A
A
C
C
C
What
did
you
say?
That
laundry
is
elevated
in
5
hours,,
so
switching
the
chain
code
itself
can
be
done
in
that
instant..
The
reason
for
this
is
that
the
chain
code
is
that
the
installation
and
instance
8
are
on
the
second
and
second
floors.
Here,
and
every
mother's
installation
says
this,.
So
when
you
become
that
lady.
Let's
go
all
at
once
and
activate
it,,
so
it
can
be
done
instantaneously,,
but
just
upgrading
the
chaincode
means
that
the
client
application
also
has
some
kind
of
school
change.
That's.
C
C
B
Mr.
Ori.
From
this
time
on
,
I
would
like
to
introduce
the
Industrial
Revolution
Center
several
times
in
the
explanation,,
but
the
content
itself
is
aimed
at
those
who
are
not
very
familiar
with
technology,
such
as
the
manager
of
the
user
company
Sanno
.
Well,.
The
framework
is
well
summarized,,
so
I'm,
an
honest
professional,,
so
I
don't
have
any
technical
details
this
time,.
So
there
are
a
few
things
that
make
Hyperledger's
tap
announcement
a
little
more
appropriate,.
B
But
if
you
understand
that
in
advance
Thank
you
for
your
understanding,
I
'm
at
the
factory
that
did
the
book,
but
I'm
a
member
of
the
company,
but
I'm,
not
sure
if
it's
correct
to
say
that
I'm
dispatched
from
there
to
the
Center
for
the
Fourth
Industrial
Revolution
of
the
World
Economic
Forum
.,
Well,
I'm
working
concurrently
with
that,
and
although
the
materials
and
formats
are
from
Hitachi
today,.
There
's
no
mention
of
Hitachi
at
all,
and
it
's
about
the
efforts
of
the
World
Economic
Forum
Center
for
the
Fourth
Industrial
Revolution.
B
Will
collect
the
top
people
of
that
country
and
the
top
1s
of
the
private
sector
in
that
system.
It's
going
to
be
an
organization
that
seems
to
be
making
efforts
to
form
a
better
first
society
than
a
normal
society.
What
is
now
famous.
Is
the
Davos
Conference,

here
are
the

intellectuals
and

I'm
sending
out
what's
called

it's
not
a
continuous
recovery,
so
far,,
but
how
to
review
the
general
society,
well,.
This
cobitious
inch
I've
been
accepted,,
but
I've
been
allowed
to
put
it
in.
It's,
an
organization
that

to
be

the
transformation.

Well,
there
are
many
parts
where
the
legal
system
and
the
so-called

regulations
are
not
in

but
among
them
is
the
technological
innovation.

maximizing

benefits
of

especially
recently,
I've
learned
that
AI
in
water
races
has
various
risks,,
but
I
often
use
the
word
"balance",
such
as
policies
that
minimize
the
risks
at
the
end.
But.
It
is
still
an
organization
that
aims
to
set
the
basic
idea
of
balance
and
receive
it
from
the
world
and
imple

it.

I
make
it,
or
how
to
write
the
problems
that
arise
there.
As
one
of
the
projects,
there
is
the
Sakurai
Chain
and
the
project
of
applying
blockchain
to
trade
and
logistics,,
and
within
this
there
are
various
white
papers,,
one
of
which
is
white
paper..
B
B
B
B

I
feel,
like
the
information,
is
a
little
outdated
on
that
day,.
So
by
Section,

Art
Skip
to
Section
6
I
would
like
to
explain
how
to
hit
234
and
7.
As
I
mentioned
earlier
,.
We
gather
people
from
various
companies,
safes,
and
academic
institutions
to
begin
with,
and
summarize
various
things
like
this,,
but
it's
not
just
that,.
It's
the
constitutional,
multiplication.
B

B
B
B
B

B

Well,
each
layer
has
its
own
point
of
view,,
but
if
you
can
tell
me
what
it
is
,,
it's
a
bit
difficult
to
visualize
this
area,
and
I'm,
sorry
that
there
are
so
many
words,,
but
first
of
all,,
business,
models,,
etc.
As
for
the
balance.
Model,
data,
standardization,
commercials,
and
the
big
enemy
is
the
sea,.
So
what
is
the
balance.
B
B
B
B
B
B
B
B
B
B
B
B
B
I,
don't
have
much
to
say
about
this
part,,
so
I'll
skip
it,,
but
I
think
that
the
trustworthy
people
involved
in
English
have
formed
their
respective
agreements
and
acted
on
their
multiple
blogs..
This
is
one
of
the
simpler
methods,,
but
it
is
necessary
to
centralize
trust
in
this
negotiator9
place,.
B
B
B
B
B
B

B

What
is
this
financial
business?
System?
I?
Don't
think
that's
the
case
if
data
exchange
goes
through
the
previous
process
at
Disney.,
Tari,
Fitting,
Yuji,
Plan
Well,,
the
supply
chain
targeted
by
this
white
paper
corresponds
to
the
business
system
called
Hime
Tin,,
but
well,
other
consortiums
are
not
enough
for
Eimei
Digital
Asset
Exchange
,
and
need
a
cold
exchange
with
a
personal
computer.
Well,,
it's
a
theorem
in
the
white
paper,.
So
it's
a
matter
of
choice,
but
umm,
well,.
There's
a
tape
saying
that
the
financial
business
is
a
reference
museum
for
discharges..
B
B
B
B
Are
similar
questions
about
platforms,
such
as
because
they
are
participating,,
but
are
participants
participating
in
the
existing
blockchain
ecosystem?And
then,
for
example,
the
licensed
prostitution
system.
In
the
case
of
comprehensive
operation,?
The
policy
of
decentralization
is
well
thought
out
by
the
general
practitioner.
Well,,
it's
okay
to
have
a
comprehensive
set
effect,.
So.
B
B
.
Well,
today
I
'm,
going
to
talk
about
interoperability,
but,
for
example,
,.
There
are
a
lot
of
booms
that
aren't
very
technical
about
learning,,
but
I
think
it
would
be
good
to
form
a
consortium
in
a
magical
way,
and
then
this
legal.
another
thing
Since
it
is
a
regulatory
system,.
Gyuri
is
a
bird's
compliance
Well,.
How
should
I
think
about
this?.
B
A
A
So,,
what
you
were
introduced
to
this
time
was
thread
paper,,
a
group
of
tools
like
this,
and
probably
later
in
Japan,,
even
if
I
thought
about
collecting
this
kind
of
information,.
It
would
n't
be
like
this
at
that.
Time.
I
thought
that
there
was
quite
a
lot
of
information
in
this
field,,
but
was
it
Japanized?.
