A
A
Schedule
.
However,
after
taking
some
time,,
let
me
explain
the
flow
of
the
day,
and
after
that,
from
6:10
to
6:50
,
for
40
minutes,
network
scaling
for
the
practical
use
of
blockchain,
Accenture's
brics
was
taken
in
the
morning.
After
that,
from
6:50
to
7:30,
without
high-end
systems,
etc.
Mr.
Tatsuya
Sato
from
Seisakusho
,,
who
is
a
city
centralized
system
operation
tool
for
the
Hyper
Ranger
public,
will
give
a
lecture
earlier.
A
A
A
A
A
Questions
that
could
not
be
answered
will
be
discussed
on
the
Hyper
Leisure
Tokyo
Meetup
page
at
a
later
date.
I
think
there
is
a
part
of
the
forum
that
we
would
like
to
answer,,
so
we
will
be
taking
a
questionnaire
in
the
middle,
or
rather
right
around
this
time,.
So
we
would
like
to
ask
for
your
cooperation.
A
A
A
I
think
it
will
be
introduced,.
So
if
you
are
interested,
,
I
would
definitely
like
you
to
fill
in
the
column,
.
I
think
so,,
but
if
I
really
want
to
learn
more
about
the
engineering
part
of
the
so-called
Hyperrecharmer,
I'd
like
to
work
on
Hyperledger,,
especially
Fabric,
and
I,
want
to
manage
the
public
operation
of
Fabric.
For,
those
who
want
to
develop,.
We
have
prepared
a
training,
little
finger,
certification,
exam,,
so.
A
,
I
would
like
you
to
take
the
four
seasons:
certification,
exam
and
training.
It's,
a
public
certification,
exam.The
ch
fa,
certified
hyperwrench
fabric
administrator
certification.
Exam
written
on
the
upper
right
is
the
so-called.
If
you
think
that
three
people
in
the
company
have
this-
and
if
you
are
a
hyperreggiano
member.
A
A
A
I
would
be
very
happy
if
everyone
could
answer
in
about
a
second.It's,
almost
always
in
the
two
Kanto
districts
,,
but
when
I
started
this
series
of
virtual
webinars
with
roots,,
it's
Kansai,,
which
I
can't
come
to
in
real
life.
We,
set
up
this
online
online
seminar,
with
the
hope
that
many
people
from
the
Chubu
region
would
gather,.
But
in
the
end
most
of
the
seminars
are
from
the
Kanto
region,,
which
is
the
trend.
A
D
C
A
A
About
48%
of
them
are
already
in
use,
and
about
70%
of
them
are
being
used
in
other
products
or
are
being
prepared
for
major
use,,
but
that
20%
are
no
longer
in
use..
This
is
wonderful,,
so
everyone,
I
would
like
each
speaker
to
deep
dive
from
now
on.
In
regards
to
the
hyper
lectures
that
are
actively
being
worked.
On.
A
C
C
C
I
am
the
owner
of
Accenture.
The.
First
time
I
came
was
in
2005.
At
first,
I
was
working
as
a
technical
support
engineer
at
a
financial
company,,
but
the
Lehman
Shock
occurred
in
Japan,
and
for
a
while
there
was
a
similar
situation.
It
was
in
2010
that
I
came
back.
Again.
Since
then,
I
've
been
working
on
that
financial
project
in
the
form
of
offshore
development..
C
C
C
C
C
Sure
there
are
people
who
are
familiar
with
the
global
6ch
p6,,
but
I've
been
given
the
opportunity
to
do
various
things,
and
there
are
8
clinical
trials
on
the
global
side
that
act
as
a
bridge
between
them.
As,
a
blockchain
sme,.
We
are
doing
activities
in
the
form
of
supporting
customers
who
bring
their
own
experiences.
C
C
C
C
Well,
biba,
it's
going
to
be
used
soon,,
so
I
think
there
are
9
jun
people
who
are
considering
it
or
are
preparing
for
it.
I.
Think
there
is
Once.
My
block
chain
part
has
come
to
four
bars,
I
have
opened
a
lot
of
covers,
and
the
company
that
is
implementing
it
has
also
opened,,
but
now
there
are
some
parts
that
are
headed
for
that
purpose.
.
C
C
C
Or
8,,
the
up-shoes
and
singer
Ami-san's
company
is
always
moving
forward,
and
when
they
say
they're
using
books
because
they're
a
little
different,,
they
say
that
they
have
to
adapt
to
that
8
Then.
The
performance
is
like
this
at
that
school.
Here
in
English,
I'm,
going
to
use
that
expression
of
resentment,.
But
if
you
say
it
didn't
suit
you,,
the
desk
is
very
high.
C
C
C
C
Longer.
Well,
for
example,
I
want
to
use
a
PC,
or,
well,
as
a
Japanese
person.
,
I
recommend
Pio
b
Group
Faroo,,
but
in
any
case,
when
I
say
I
want
to
try
it.
Out.
Let's
spend
a
lot
of
time
on
the
day
and
do
something
like
this
first
poc
Or,
after
all,.
It
would
have
been
better
if
the
platform
was
different,.
So
let's
go
through
the
poc
again.
C
C
C
C
I,
don't
think
there
is
a
company
that
will
invest
in
it,,
so
I
think
there
are
some
things
that
need
to
be
solved.
As
for
the
lack
of
population
or
whether
we
can
support
it,
first
of
all,.
The
beauty
fr
pitcher
that
I
mentioned
earlier
will
be
based
on
this,,
and
it
will
be
the
one
that
has
already
been
introduced,.
So
we
will
consider
it
first,,
including
security.
C
C
C
It
's
expressed
as
a
blockchain,
page.
However,,
mighty
cold
weather
or
Matty
Cloud
deployment.
This
is
also
in
the
form
of
a
problem
that
is
quite
a
stem
twist
,
and
among
the
participants
there
are
companies
that
use
8,
aws
cards.
There
are
some
collectors
who
use
cards.The
idea
that
it
is
possible
to
introduce
Maficloud
at
the
right
time
is
also
being
taken
into
consideration.Well,.
The
infrastructure
is
already
completely
independent,
.
Originally,,
it
was
Eto
Pocha
in
the
company,,
but
after.
C
C
And
of
course,
I
played
it
at
the
beginning,
and
then
Apisbent
was
added.
Including.
The
fact
that
the
base
for
wintering
is
taken
away
and
vinegar
is
used,,
but
on
top
of
that,
,
Puma,,
which
is
already
supported
by
Puma,,
has
a
fabric
called
Windy
Beast,,
a
hot
folder,
and
Koran.
We
already
have
8
Fair
Warp
supports,,
but
we're
currently
adjusting
various.
C
C
C
C
C
C
C
C
C
That
's,
why
I'm
going
to
ask
various
companies
to
take
it
to
a
p
bag,
and
if
it's
possible,
I'll
ask
them
to
omit
an
anucha
and
make
it
bigger
with
a
mogu,,
so
I
'm,
going
to
open
it.
We
have
a
source
car
Distribution
It's
a
little
very
easy
Um,!
That's
good,,
but
I'd
like
to
touch
on
a
few
points.
C
C
Of
course,,
you
can
use
the
design
as
it
is,,
but
the
reason
why
I
want
to
change
a
part
of
it
is
that
it's
tied
up.
With,
that
in
mind,,
when
it
comes
to
8
designs,,
we
are
implementing
that
module.
Modularization.I
touched
on
Pivo
a
little
bit
about
Pretty
Cure,,
but
I
didn't
use
pre-impressions
in
the
sources
or
the
population.
File.
It.
C
A
C
C
C
Go
through
the
winter.
We
are
inviting
various
people
to
events
such
as
Papa's
Leisure
events
in
Japan
today,,
but
we
are
responding
to
events
where
we
announce
them
as
needed
and
focus
more
and
more
on
those
participants.
My
shins
are
the
best,,
but
as
a
French,
pink,
um,
on
this
day,
I'll
share
my
art
as
a
pink.
C
C
A
C
A
C
A
A
C
A
D
D
D
System.
It's
called
sc,,
but
we're
developing
something
like
that.
A
system
that
knows,
and
utilizes
Brock-chan
8a,
abbreviated
as
Maker
6ch
System,,
but
its
system-like
characteristics
are
that
it
is
composed
across
multiple
organizations,
and
among
them.
Is
the
Kushiro
Organization.
We
believe
that
there
is
value
in
the
fact
that
the
execution
of
wintering
transactions
can
be
performed
centrally.
.
D
D
D
D
D
D
D
In
terms
of
managing
the
operation
of
a
unique
system,
for
example,,
you
can
use
the
smart
contact
to
support
the
application
after
that
,
or
you
can
take
a
slapshot
of
the
dirt
data,
and
so
on.
It's
a
little
late,,
but
I
think
that
this
blockchain
system
has
the
characteristic
of
being
structured
across
multiple
organizations,
or
rather,
management
domains.
.
D
D
D
D
Jobs
like
that.Um,
I
would
like
to
dig
a
little
deeper
into
this
one
problem,,
but
there
are
various
conventional
system,
operation,
management,
tools,
and
in
the
old
days,
that
kind
of
job
From
things
to
the
management
server,
well,.
It's
been
the
last
few
years,
like
iac
to
infrastructure,
support,
.
D
Improve
the
efficiency
of
the
operational
work
that
is
closed
to
the
unit
organization,
and
in
the
first
place
there
is
no
interaction
with
the
top
management
regarding
the
operation
of
the
organization
Matagi..
To
say
that
there
is
no
Well,
I
would
like
to
think
a
little
more
about
what
would
be
a
problem
if
I
didn't
take
this
into
consideration,,
but
as
a
method
of
managing
funds,
a
little
more,
as
a
method
of
getting
early
summer,
for
example,.
There
is
a
single
and
practical
method
like
this.
D
A
D
D
D
D
D
As.
Many
of
you
may
already
be
aware
of
the
fact
that
the
Needle
Gate
approves
multi-organization
Gunray
transactions
in
the
mansion,
model,
I
'm,
not
sure
about
that
zone.
Region.
However,
there
is
Red,
and
it
uses
the
initial
name
of
the
private
key
issued
by
it
to
identify
clients
and
peers
as
users
of
the
organization,
and.
D
D
D
D
D
D
D
D
D
D
For
example,,
peers
and
mandos
are
used
in
their
operations
to
help
their
superiors,,
but
such
things
have
been
clarified
considerably
,
and
in
the
Edo
v1
system,
parameters
determined
by
a
specific
organization
a.
In
other
words,,
the
single
point
of
trust
remained,,
but
that
kind
of
thing
is
being
eliminated.To,
be
more
specific,
from
the
av
2.0
series
,
a
good
thing
called
New
Gen,,
Life
Cycle,
has
been
introduced.,
Improvements
have
been
made
here
and
there.
D
yeah
I'm,
just
thinking
that
there's
still
room
for
improvement
for
us,,
and
it's
true
that
this
9
Sashun
is
good,
but
in
reality
,
for
example,
I'm
trying
to
compete
with
the
pros
in
the
Olympics
over
the
winter.
Then,.
It
is
necessary
to
combine
and
execute
these
tasks,
and
I
think
that
end-to-end
operations
can
still
be
made
more
efficient
in
terms
of
workflow.
The
work
that
should
be
done,.
The
adjustment
work
of
the
organization
matagi
that
occurs
at
that
time,,
whether
it
is
an
information
threat
or
parameter,
matching,,
etc.
Well,
on
the
contrary,.
D
There
are
some
parts
that
are
increasing,,
so
I
think
we
can
reduce
them.
So,
here.
I.
Am
writing
an
example
of
deploying
the
Gencode,
and
each
organization
needs
to
approve
this
chain
definition
using
exactly
the
same
parameters
as
other
organizations.
.
What
is
being
used
in
some
organization?
Or,
the
source
code,
itself.
Blocking,
that
kind
of
thing
in
time,
8
Well,.
If
you
need
to
share
or
coordinate,
you
have
to
do
it
outside
of
this
system.,
Well,
I
think
it's
going
to
be
a
typical
example.
D
D
D
D
D
D
D
D
D
D
D
D
D
D
D
D
D
This
process
has
become
quite
troublesome..
First
of
all,.
A
certain
organization
generates
a
transaction
for
the
setting
if
it
can
be
heard,
and
then
collects
signatures
from
the
Senkaku
organization.
Update.
When
the
number
of
signatures
exceeds
a
certain
amount
When,
you
type
a
command,,
it
will
be
Mr.
Marko,
well,
like
the
chain
code
,.
It
needs
to
be
shared
with
other
organizations.
.
D
D
D
D
D
D
D
D
Information
will
be
transmitted.In
the
next
step,,
the
other
organizations
will
perform
the
groove,,
and
since
there
are
currently
three
organizations,,
a
majority
will
be
obtained,,
so
this
chain
code,
Gaiden
top,
will
be
issued,
and
each
organization's
agent
will
receive
it.
Well,.
According
to
this
event,
I'm
deploying
around
the
deployment
chain,.
So.
D
D
D
D
D
A
D
D
D
In
order
to
raise
the
concentration
of
ions,
overwintering,
well,,
a
natural
config
block
and
something
like
the
so-called
Jenny
seed,
block,
uh,
tell
the
stake
to
get
it,
and
that
rubyon
uses
that
information
to
raise
its
own
concentration..
Raising
the
wintering
here
is
done
outside
the
inoculation
put
cold.
D
D
D
D
A
If,
you
have
a
question
for
Mr.
Sato,
I
would
like
you
to
ask
me
that
question
from
that
Q
&
A
button,,
but
there
are
already
a
few
questions.,
maybe
Is
it
true
that
the
rumor
that
Japan
and
India's
digital
currency
demonstration
experiment
is
being
conducted
on
the
third
floor
is
true.
What
kind
of
milk
experiment.
D
A
I
understand.
I
would
like
to
ask
for
your
understanding
that
it
is
about
enjoying
the
time.I.
Also
have
one
more
question.It
is
my
understanding
that
the
reliability
of
event,
services
for
children
with
disabilities
is
not
very
high,
and
that
we
need
to
work
hard
in
various
ways.
I,
wonder
if
it's
already
implemented
as
a
perfume,,
but
it
's
a
sumo
wrestling
match,,
but.
A
A
If
there
is
,
I
would
like
you
to
write
it
on
the
board.
Thank
you
for
your
question.
Fabric
is
the
relationship
between
peer
and
channel
The
relationship
between
peer
and
chain
code
When.
The
structure
is
flexible.
Pop
ops,
sc,
It's,
northern
bus
pops,
I,
don't
know
what
you
mean,,
but
it's
not
that
difficult
to
define
the
local
settings
necessary
for
this,
and
I.
Think
it's
probably
in
Thailand,,
etc.
D
Think
about
that?
I'll
be
gone
However,
the
tool
itself.
This
time
is
specialized
in
sharing
information
across
organizations,
and
the
part
of
individual
settings
from
the
draw
has
not
been
done.
Yet.
There
are
things
that
can
be
done
flexibly
in
the
morning
settings,,
but
I
think
that
there
are
parts
that
are
quite
dependent
on
the
environment,.
So
there
is
a
condition
that
the
priority
of
replies
is
lowered.
.
A
D
Improvements
have
been
made
in
terms
of
the
results
of
successful
failures
as
this
transaction,,
but
when
comparing
the
results
by
inserting
actual
logs,
for
example,
and
analyzing
the
match
or
discrepancy,
this
time,
It's
not
really
included,,
but
I've
used
age
in
the
processing,.
But
in
that
form,
it's
better
than
horses,.
So
I'd
like
to
add
processing
that
increases
reliability
as
part
of
its
operational
work.

B

So,
I
talked
about
that
kind
of
technology,
and
since
there
is
a
stage
like
Hyper
Laser,,
let's
try
to
do
it
only
with
audio,.
So
from
2019,
there
was
a
talk
by
Tori-san,,
who
was
the
leader
of
Accenture's,
struggling
char
3rd
place..
Both
of
us
made
a
simple
triangle
with
hyper
substances,
and
that
2022
pan.

It's
a
cheap
version
of
the
staged
version
of
Nice,,
but
this
is
not
a
group.
Chain.
Transactions
between
Dacers
managed
through
block
tiers,
are
executed
by
calling
the
API.
His
wife
In
terms
of
the
scope
of
disclosure
of
major
os,.
There
will
be
a
movie
and
software
that
allows
transactions
between
people
on
a
certain
block,
chain.
B
B
Well,
this
is
the
overall
blueprint,,
but
this
current
blueprint.
Currently,
there
are
16
projects
like
this,
and
among
them,.
Cactus
is
an
integrated
type
that
is
realized
by
secure
interconnection
of
pop-up
blocks
and
enter.
A
library
that
prepares
service,
watches

It
's,
positioned
as
a
tool
that
looks
like
it's
starting
from
hairless,.
So
it's
positioned
as
a
5-jet.
B
B
B
Blocker
c,,
etc.
Already
on
that
route,.
If
it's
different,,
it's
public,,
it's
okay,,
it's
like
this,,
and
it's
something.
That's
already
been
returned
to
this
professional
chain.
As
for
the
sun
of
that
task,
in
particular,.
We
have
realized
two
other
verifiers
in
concentration
servants,
,
using
validators
and
two-way
communication,
and
abstraction
for
balls.
In.
This
case,.
We
are
doing
a
process
that
absorbs
the
difference
of
a
small
block.
Chain.
B
B
B
B
.
And
so
on,
those
developers
are
currently
participating,
yes,.
There
is
also
a
block
change
version
called
Biter,
Stop,
and
Mart
says
that
this
is
the
market,
and
rain
costs
are
8,
plummers,,
3,
types,,
clients,,
etc.
Also,.
If
the
guidance
provided
by
financial
institutions
has
been
returned,,
they
have
also
said
that
this
is
a
Mao
or
Valley.
B
B
B
B
B
B
B
B
B
I
think
that
business
plug-ins
will
continue
to
increase
more
and
more
than
6,000
types
of
fick,.
So
we
plan
to
provide
champloo
that
responds
to
that.
In
the
same
server
of
building
a
building
like
this
b
006
sample
sample
alley.
I
would
like
to
strengthen
the
sdk
for
software
developers
to
start
developing
more.
B
B
B
B
Terms
of
version
I,
well,.
After
releasing
the
right
scanty,,
there
was
also
Pare
Jacquard,
Yappa
Junko,,
so
I
'm,
not
sure
if
I
can
proceed
as
planned.
It's
a
bit
difficult
to
make
a
down
silver,,
but
as
a
flower
or
a
person,
I'm,
going
to
remove
it
every
day,
so
that
I
can
put
it
on.
With
this
planning,
and
I'm
going
to
support
it.
Every
day.
B
Attracting
and
encoding
the
pub
car,,
which
is
a
dream
sample,,
is
also
done,
and
as
a
settlement
function
for
that
result,
Ethereum
Native
2
is
managed.
It's
a
different
way
of
talking
about
connecting
blockchains,,
but
it's
working
,
and
the
second
one
is
the
fal,
f,
2
b.
Trade.
This
is
a
fully
automatic
payment
application
that
responds
to
the
amount
of
power
charged,,
such
as
a
smartphone,,
where
multiple
charges
can
be
automatically
paid
from
the
user's
account.
B
B
And
after
that,
as
a
function
related
to
the
middle
of
the
day,,
it's
assumed
that
Kisaki,
Nei
Kids,,
Ao-,
Yaku,
,
and
so
on.
Um,
that
event
or
something
like
that,,
and
it's
raining
on
the
story
that
it's
okay
to
catch
it,
and
that
last
supply
chain,
application.
Well,
for
example,.
There
are
various
types
of
parts
to
be
transported,
such
as
knobs
here
and
wood,,
but
depending
on
the
type
of
such
parts,.
This
part
will
be
classified
according
to
the
type.
B
B
Teen
cooperation,
patterns.
I,
will
explain
the
flow
of
ownership
transfer
of
a
car
Well,,
as
shown
in
this
figure,
first
of
all,
that
Ethereum
2
Polio
network
and
Hanyu
Public
Parker's
chain
king
got
on
the
chain
around
the
car.
I
bought
these
two
on
the
premise
that
there
is
such
a
thing
as
a
big
blade,
and
during
my
life,.
B
Coordinated
movements,
so
as
a
step
fan,,
this
seat
with
good
rotation
will
come
cheaply.
In
contrast
to
Tatsu,
this
9
man
is
still
the
person
I'm
looking
at,,
but
this
person's
possession
Well,
a
man
who
wants
to
rent
a
car.
That's
in
the
middle
of
nowhere,,
every
year,,
I
'll
push
it
more
than
a
one-shot
response
to
ownership.
Rights.
B
B
B
B
B
B
B
B
B
B
B
B
B
B
B
B
B
B
B
B
B
B
B
B
We
have
released
3
types
of
visual
samples,,
such
as
those
that
prevent
the
device
from
charging,,
such
as
the
a
ridge
and
the
tips
of
the
hair.
In
addition,.
We
plan
to
increase
the
number
of
collaboration
patterns
for
6
companies,,
and
we
also
plan
to
provide
an
SDK,
which
will
not
be
implemented.
B
B
B
B
B
B
In
terms
of
that,
I
want
to
make
it
even
more
powerful
than
it
is
now,
and
what's
necessary,
for
that
is
the
Poseiengineering
ability
and
Zest,.
But
after
that,
it
seems
that
I
want
to
use
it
for
solving
things,,
such
as
those
cases
where
I'm
going
to
get
it
from
everyone.
.
I
think
that
the
request
will
be
quite
the
key,.
So
it's
fine
for
those
who
are
like
that,,
but
if
you're
interested
in
that
kind
of
aputatsu
in
various
ways,,
you
can
use
your
papa
's..
B
B

B

There
was
also
a
time,
but
I
wonder
if
there
will
be
another
method
for
issuing
such
a
statement,,
so
well,,
it's
just
that
I'm
married,.
So
how
much
security
should
I
leave
on
that
day,
or
how
much
should
I
entrust
vision,
logic,
to?,
By,
the
way,
in
the
second
semester,
I
think
I'll
sell
it
to
people
who
use
it
in
a
lot
of
different
ways,.
So.
B
A
A

I
got
it,,
but
eh
Originally,.
That
model
is
that
Fujitsu's
wintering
connection
chain
is
that
Yukichi
and
that
evil
battle,
Cha-san's
Dormer
block
to
the

framework
Well,.
These
two

Well,
that

wintering

is

terms
of
the
fact
that
there
is
no

we
are

After
all,
I
myself
have
tried
to
do
a

of
different
things,,
but
I've
been
doing

of

But
it's

c
There
are
quite
a
few
insanely
strong
people,,
so
I
can
get
information
now,,
so
well,,
well,,
well,
well,.
That's
why
people
will
answer
that
they
should
run
away
from
the
rear

and
my
