A

D
D
D
So
the
first
topic
is
and
how
does
how
does
if
the
event
can,
if
the
attribute
value
can
be
sourced
from
the
event,
as
well
as
from
the
function,
and
then
how
does
it
work
in
reality
and
that
we're
working
working
through
the
process?
This
is
just
the
first
time.
I
present
this
I'm
thinking
can
change
anytime
and
if
you
provide
any
suggestions
and
to
explore
different
ways
to
design
it,
okay,
so
first
starting
from
here.
This
is
a
very
simple
example,
and
we
assume
the
case
where
this
is
the
zoom.
D
D
E
D
D
So
my
who
was
it
my
mother
and
my
kid
and
had
this
about
three
weeks
ago:
we
thought
it
was
common
cold,
but
then,
after
that
he
never
recovered.
So
it's
coffee,
it's
almost
three
weeks
now
but
sure
and
there's
no
there's
no
fever
and
there's
no.
How
that
symptom?
We
caught
up
call
me
tonight
and
you
see
that
this
doesn't
qualify
as
a
conveyed
potential
case
and
then
just
we
just
waited
and
then
weird
enough.
There's,
no,
nothing
except
coffee.
So
so
I'm
not
super
twitchy.
D
D
D
D
D
C
Point
can
we
we
just
clarify
something.
So
the
summary
for
what
you're
doing
is
this
is
the
purging
Katia's
on
new
events.
Oh
yes,.
C
D
Good,
okay,
let's
tricking
yep,
so
this
is
a
example.
First,
you
Kasasa
there
menu
change
from
new
new
menu
from
managing
demand.
I
can
get
it
from
a
function,
call
to
get
locality.
71St
Street!
You
have
fine,
you
can
change
it
from
letting
change.
You
can
get
the
new
street
value
from
venue
to
venue
change.
A
little
code
is
not
control
right.
So.
D
D
Empty
it
can
simply
fetch
the
lake
is
the
event
that
matches
the
criteria
and
get
the
value
from
there,
and
if
the
cage
is
not
empty
it,
if
the
case
is
not
empty,
the
engine
can
simply
in
that
find
all
the
events
that
happen
between
the
caged
value.
Every
time
you
have
kids
to
actually
Beauty
also
change
the
block
height,
so
you
can
find
you
can
find
out
all
the
events
that
happens
after
that
that
block
height
and
it
has
to
run
the
latest
one.
So.
D
Good
okay,
okay,
there,
but
I
will
actually
provide
a
reason.
Why
sometimes
you
need
you
need
to
get
local
King
Street,
and
my
suggestion
is
the
first
time
if
the
if
cage
is
empty,
it
should
fetch
its
value
from
from
the
smart
contract
function,
call
and
but
that's
just
what
I
think
now
can
discuss
that.
So
from
this
point
on,
I
should
be
using.
The
word
called
blocks
token
script
engine-
and
this
is
the
creation
from
tamazaki.
D
The
the
reason
being
that,
if
we
see
he
was
our
agent,
then
it's
not
not
toxic
engine
does
not
necessarily
working
user
agent,
so
you
can
imagine
that
being
deployed
on
the
super
load.
For
example,
in
order
to
index
all
production
layer,
sorry
talk
a
layer
because
I
talked
with
that
had
two
other
services.
D
D
B
D
B
Does
it,
for
example,
in
this
example
in
mine
18,
on
the
pen
on
the
right,
it
should
listen
to
the
venue
change
event.
Listen
for
that
event,
even
if
I
modify
the
token
script
file
to
remove
this
event
from
from
this
file
because
the
token
script
engine
is
it
responsible
for
unsubscribing
to
it.
So.
D
D
D
C
You
mean
if
it's
if
it's
say,
I'm
browsing
from
a
webpage
and
I'm
looking
at
a
token
and
but
I,
don't
I
have
not
specified
the
owner
address.
Is
that
remember?
Oh
no,.
B
D
D
C
D
D
Sorry
wait
a
moment:
I
thought
that
line
is
a
different
one,
so
this
one
addresses
in
such
way
that
the
logic
is.
If
there
is
a
band,
and
then
you
read
that
that
happened
an
event
when
I
think
that
I
mean
if
there
is
occasionally
event.
That
means
events
are
caged.
If,
if
there
is
no
event
in
the
cage,
then
we
have
to
find
the
we
have
to
refresh
the
page
or
we
can
call
contract
I
recommend
the
strategy
to
be
calling
contract
instead
of
refreshing,
eval
cage.
C
C
I
know
they
are
SC
right.
Okay,
so
that
etherium
call
module
is
the
is
the
thing
to
do
if
there's
no
well.
D
D
So
this
one
okay,
then
there's
second
problem
that
if
there,
if
there
is
no
way
to
get
it
from
the
function
right,
so
that's
a
that's
a
issue.
For
example,
if
only
we'd
get
it
from
event
is
from
event.
Yet
there
are
two
events:
one
is
called
even
evil
occasion
when
the
other
is
called
value
change.
When
you
changed
because
the
smart
contract
authors
didn't
even
try
to
get
her
and
that
happened
right
so
then
that
is
case
might
be
need
to
be
solved.
But
can
we
come
back
to
solve
this
issue
later?
D
D
B
D
D
D
D
D
D
C
D
B
D
B
D
D
Next
release
with
email
support,
we
would
not
have
performance
at
the
Vantage,
which
is
okay,
okay,
I
see
so
so
so
so
so
that
this
is,
you
know
people
will
say
what
why
do
I
have
at
event?
Is
it
for
performance
or
is
it
for
notification?
Support
and
I
will
say
mostly
for
not
official
support
and
also
for
performance,
but
sometimes
performance
scale
is
visible,
as
in
the
previous
example,
and
sometimes
performance
can
isn't,
isn't
there
and
it's
even
it's
just
there
for
for
so
so
to
the
end
of
definition,.
D
D
D
D
D
B
D
D
B
D
D
D
D
D
B
D
C
The
dependency
tree
is
definitely
not
complete,
but
the
the
dirty
marking
when
I
just
use
a
heuristic.
We
can.
We
talked
about
designing
it.
Basically,
if
the
end,
if
the
call
is
on
a
contract,
that
is
not
a
token
or
it's
a
token
that
we're
not
tracking,
then
it
doesn't
catch
the
value
it
just
always.
Fetches
I.
D
D
C
D
Make
it
shareable
between
Android
iOS,
and
it's
not
so
easy
to
do
it,
because
it
also
have
to
add
an
Access
database,
but
if
this
work
has
not
been
started
and
when
they
consider
putting
that
into
some
kind
of
library,
but
this
is
going
to
get
into
long,
I
will
focus
on
the
current
one
okay.
So
this
is
related
issue,
not
not
the
one
we
are
talking
about,
and
so
next
one
is
in
some
cases
an
attribute
value
is
so
bad
at
I/o.
Then
it
changes
on
every
block.
This
is
typical.
D
B
D
C
D
That
case,
we
simply
cannot
generative.
You
have
to
leave
it
blank
and
then
load
it
later,
and
this
is
a
very,
very
bad
design,
because
it's
going
to
invite
abuse.
Somebody
is
going
to
put
cash
across
the
force
during
debugging
for
every
attribute
and
then
will
he
sense
it.
His
still
will
never
be
generated
instantly,
always
always
generated
later
than
other
beams.
D
D
D
B
B
D
D
D
D
D
D
D
D
B
D
E
D
Yeah,
so
so
what
you
can
do
is
to
jibberish
CSR
and
somehow
make
it
past.
The
authorities,
security
perimeter,
so
they're
tortured
by
accidentally,
have
to
have
signed
something
we
are
yet
married
dangerously
and
if
you,
if
you
can
carefully
find
a
way
for
them
to
sign
stupid
stuff
that
breaks
the
security.
If
we
require
CSR
to
be
signed,
then
the
adversary
has
has
to
not
only
create
the
crafty
message
to
be
signed,
but
also
somehow
create
the
corresponding
private
key,
which
will
we
will
be
as
difficult
as
breaking
pranky
yeah.
