A
Hello
everyone,.
We
continue
the
course
of
developing
the
amount
of
contracts
to
grow
for
training.
There
is
no
protocol,
my
name
is
Vadim.
Ilyin
I
represent
the
world
I
work
in
the
dvl
department.
We
have
already
held
two
classes
today.
It
will
be
what
we
call
advanced
work
in
a
smart
contract.
We
analyze
many
things
and
superficially
in
the
past
times,
so
that
not
to
concentrate
much
on
such
complex
topics.
A
Today
we
will
try
to
delve
into
each
part
of
which
we
have
analyzed
so
far,
I
will
show
some
things
that
will
be
useful
to
you
if
you
start
doing
some
projects
on
it
in
general,
in
general,.
We
have
two
lessons.
Left,
I
plan
to
the
next
lesson
is
to
make
a
release
on
testing
and
migration
of
contracts.
So
there
are
quite
a
lot
of
different
things
and
probably
the
last
day
we
will
finally
analyze
a
big
project.
A
A
So
that
means
we
have
done
two
classes
and
we
learned
more
or
less
somehow
crookedly
askance,
but
no
less,.
You
can
write
code
at
a
time
with
you,
we
can
compile
it,
I’ll
take
files
using
the
library,
don’t
grow
krs,.
We
can
deploy
our
blockchain
code
using
the
don’t
erzi
play
command,
and
we
can
create
a
yuval,
that
is,
an
interface
and
some
applications,
sites
or
how
then
the
interaction
with
our
contracts
with
the
help
of
the
world.
Again
with
this
is
a
library
for
javascript
and
the
dough.
A
Let's
start
with
it
again
with
this
library,
it
is
present
in
npm
that
is,,
if
you
suddenly
want
to
build
your
own
from
scratch
the
product
before
we
did
it
clone
some
examples,
and
it
seems
to
me
really
an
ideal
way
to
start
working,
that
is,
you
can
take
some
example
more
suitable
on
the
site
and
to
the
castle.
world.
.
word:
May.
Each
lesson
was
looked
at
to
choose
something
suitable
there.
All
the
necessary
interaction
will
already
be
written
and
just
finish
it
for
your
tasks
would
be
removed.
A
You
don’t
need
to
add
the
necessary
ones.
If
you
want
from
scratch,
then
you
can
create
a
new
pro
new
project
on
audi,
install
npm
commands
install
the
world
and
5s
it
becomes
yours
and
accordingly,
you
can
connect
your
smart
contracts
to
your
application.
That
supports
javascript
import
of
this
library
into
the
landing
net
is
performed
by
such
a
usual
line,
import,
something
like
nerves,
5
from
friends,
not
rogers,
then
from
this
variable,
not
cancer,
and
you
can
pull
out
a
lot
of
useful
things,.
A
A
If
you
suddenly
need
to
sign
or
jerome
jerome,
you
will
sign
in
any
case,
they
won’t
growl
and
everything
will
be
taken
care
of,.
You
don’t
have
to
worry
about
this
at
all,.
We
can
simply
and
easily
send
the
team
the
blockchain
keys,.
You
will
need
to
pick
up
this
very
niera
5,,
but
with
the
magic,
let’s
go
further,,
then
we
need
to
configure
our
connection
here,
it’s
important
for
us
to
specify
the
type
of
network
that
we
will
use,.
We
have
always
worked,.
You
can
always
squeeze
it
in,.
A
It
will
be
possible
later,
with
the
time
of
acceptance,,
when
you
are
ready
to
launch
on
the
Internet,.
There
are
some
wallet
addresses
in
this
explorer
and
the
letter
itself,,
and
where
your
users’
requests
to
exchange
will
go,,
they
will
go
to
such
a
person
from
processed
in
the
form
of
a
private
buche,.
They
don’t
go
anywhere
from
your
client’s
computer,.
Then
we
will
create
a
world
object
and
a
currency
object,.
We
won’t
also
need
it
in
order
to
do
the
things
we
need
in
the
application,.
A
A
We
will
need
to
specify
exactly
the
contract
that
we
want
the
user
to
authorize
his
account
with
a
certain
name
that
will
appear
on
the
screen
when
he
converts
to
this
application,
and
then
there
are
two
parameters
where
you
need
to
redirect
the
user.
In
case
of
success
and
in
case
of
failure,
for
example,
there,
the
user
does
not
have
a
wallet
and
he
may
not
be
able
to
connect
and
returned
somewhere
to
your
page,
where
you
will
say
how
to
create
a
wallet.
If
he
does
everything.
A
A
Acta,
this
is
done
where
this
is
also
at
the
beginning.
When
you
initialize
your
application,
we
will
make
a
fresh
new
object
of
type
world
and

.
contract.
Here
we
indicate
the
account
and
the
contract
the
name
of
the
contract,,
that
is,
in
our
case,
when
we
did
the
test,.
These
are
some
kind
of
complicated
devs
there
minus
what
they
created
there
gives
you,
or
you
can
create
your
own
name
and
write
it
down
in
it,
that
is,,
it's
some
the
contract
that
you
manage.
A
Where
you
want
that
your
user
accessed
to
work
with
applications,,
then
we
specified
view
methods
and
repair
methods.
If
you
remember,
we
had
very
increment
methods
in
the
method
were
get
to
us
for
our
account
counter,
respectively,.
We
can
write
some
methods
here
in
the
case,
if
we
need
and
some
kind
of
account,,
this
is
an
object
that
we
created
earlier,
that
is,.
A
If
we
do
everything
right,
again,,
you
can
just
take
the
code
from
the
code
examples,,
you
will
practically
play
the
contra
contra,,
you
will
copy,
the
methods
will
change
and
everything
will
work,
and
actually
this
flesh
and
blood
is
already
on
your
application,.
This
is
a
method
for
reading
from
the
blockchain
and
for
writing
to
the
blockchain.
We
read
by
the
method
brought
out
the
meat.
Then
we
have
this
as
a
contract
.
view.
My
ass
here
is
some
kind
of
here.
A
It
happened
to
be
our
grandfather
and
we
indicate
the
parameters
that
we
need
here,
which
we
will
send
to
the
input
of
our
function.
After
that
we
get
the
optimality
of
the
feature
and
weight
that
is,.
We
will
definitely
wait
until
the
execution
of
this
method,
and
after
that
we
will
go
further
and
example,.
We
can
output
to
the
console
the
number
that
we
received
due
to
the
blockchain,.
If
we
want
to
use
or
record
something
on
the
blockchain,
for
example,
some
action
of
ours,,
your
application,,
then
we
indicate
in
essence
in
the
same
way,.
A
Only
we
attach
here
later
see
the
gas.
This
is
an
optional
parameter.
If
you
do
not
specify
a
certain
default,
value
will
be
transferred
and
a
certain
number
of
rivers
toner
for
these
tokens
that
we
are
ready
to
send
with
these
requests.

This
is

4
degrees
of
the
world
of
units,
that
is,.
In
order
to
transfer
one
such
there.
We
must
write
40
here,
sister
did
it
so
that
we
do
not
store
the
fractional
part
in
training,.
A
We
store
the
integer
there
for
optimization,
and
here
an
important
note
was
hinted
around
the
room
that
if
we
pass
tokens
to
a
parameter,,
then
every
time
it
will
call
the
wallet
interface
and
the
user
will
press
the
confirmation
of
this
request
right
in
the
wallet,
because
we
do
not
allow
the
application
to
spend
money
without
asking.
If
it's
just
some
kind
of
method
which
is
not,
I
will
be
happy
as
a
user
after
leaving,,
then
we
can
do
it
simply
by
pressing
a
button.
A
If
everything
is
connected
in
advance,
there
is
a
key
in
the
browser’s
memory,.
Then
this
method
will
be
executed.
Automatically,
probably
it’s
worth
mentioning
here
that
each
key
has
a
certain
kia
lovins,
that
is,
there
is
no
permission
to
spend,
which
it
is
possible
when
writing
out
this
key,.
This
is
done
so
that
some
key
cannot
spend
too
much
money,
that
is,.
It
is
given
to
this
small
amount
and
it
cannot
spend,
for
example,.
A
In
the
case
of
a
game,,
a
person
will
be
able
to
complete
some
set,
I
don’t
know,
let’s,
say
500
purchases
on
the
marketplace
until
he
has
the
key
gradually
you
work.

wookiee
allows

Beyond
this,.
It
is
possible
that
either
you
ask
the
user
to
re-login,
or
you
can
re-issue
the
key
to
his
eyes,,
give
him
a
new
one
and
the
same
balance
of
gas
for
each
specific
key,
again,.

These
are
the
things
that
I
wrote
out
in
the
presentation.

it
will
be
attached
to
this.

I
will

a

here
is
an
incredible
amount
of
these
examples
of
some
africa
so
that
you
can
go
over
later
and
see
those
use
case
that
you
will
need
to
work
with
it
part
5,
for
example.
Here
you
see
the
connections,
let's
see
together,
so
what
we
can
do.
We
can
create
an
account,
for
example,
because
we
connected
not
r,
again,
with
further,.
A
It
will
be
setting
the
config
about
what
we
talked
about
and
creating
an
account,.
Here
we
are
on
the
ship
story,.
We
create
some
key
phrase
using
the
standard
methods
of
the
province
key
phrase,,
someone
gets
a
pair
of
private
key
and
public
key
after
To
do
this,.
We
add
a
public
key
and
send
a
transaction
so
that
this
amount
of
communication
is
added,.
An
account
is
created
with
a
key
from
the
test,.
After
that
the
user
will
already
be
able
to
already
have
the
gift
of
this
account
to
sign
some
transactions
from
it,.
A
Separately,,
you
can
work
with
some
with
specific
keys,.
There
are
also
examples,.
You
can
delete
keys,.
All
this
is
registered
for
you,.
You
can
take
it
and
see.
It
will
be
possible
to
check
the
status
of
transactions
by
sending
them,.
Let's
say
here
for
this
operation,.
If
something
will
happen
for
a
very
long
time
or
you
are
waiting
for
some
kind
of
transaction,,
you
can
hang
some
kind
of
spinners
and
wait
until
the
need
comes
the
status
of
many,
many
different
actions.
A
Here
you
can
perform,,
you
can
wrap
transactions
in
a
set
and
made
in
order
to
admit
that
we
don’t
need
to
fake
something
to
perform,
in
principle,.
We
are
not
interested
in
making
a
person
stop
half
way,,
so
we
can
pack
several
mutations
at
once
into
one
set
and
wrap
it
all
together
in
one
signature,
a
person
does
everything
at
once,
and
thus
we
create
an
account.
We
switch
to
some
money
immediately,
send
the
name
of
some
contract
to
the
network
and,
for
example,
initialize
the
contract
on
this.
She
has
special
utilities
here
for
example,.
A
You
can
see
and
deploy
the
contract
directly
from
the
e
code.
If.
You
need
us,,
we
can
count
the
gas
that
we
have
used,
up,,
withdraw
it
to
control
the
gas
that
is
spent,
ignites
on
all
kinds
of
calls,
check,
the
status
of
the
account,
look
at
its
deposits
and
others,
for
example,.
In
this
way,
you
can
make
sure
that
the
account
is
real
in
front
of
us
or
not,
if
in
with
a
deposit,
it
means
it
is
real.
We
can
wrap
the
world
and
we
can
check
the
signatures.
A
A
There
are
such
forms
where
people
write
programs
without
any
code
at
all
that
is,,
you
can
simply
import
files
there
without
javascript,,
but
in
fact
the
kinsey
plugin
call
to
do
and
so
that
they
send
transactions
to
a
block
whose
general
links
I
will
leave,
I
hope
that
there
are
some
on
top,
where
the
main
thing
I
described.
If
you
need
deeper
things,
then
just
look
here.
Our
engineers
have
written
down
quite
a
lot
of
useful
things,
so
there
is
also
a
pm
format.
Here,
for
example,.
You
can
format.
A
A
These
will
talk
more
deeply
about
the
deployment
of
the
contract,,
which
means
when
we
wrote
some
code
on
the
side
of
the
blockchain.
We
have
to
create
this
important
assembly
file,.
The
file
that
we
bukchin
and
peoples
will
leave
then
execute
no
one
to
the
virtual
machine,,
thus
guaranteeing
that
on
each
server
the
code
will
be
executed
in
a
similar
way
and
will
give
a
predictable
result,,
which
means
that
the
command
not
rdv
diploma
in
in
this
case,.
A
A
In
it
pk
165
showing,
but
from
the
previous
lessons
1
of
each
specific
product,,
we
can
see
what
kind
of
account
it
had
created.
If
we
go
to
the
nerdist
folder,
here
there
is
a
button
to
do
it
started
for
this
contract,.
Such
an
account
was
created
the
command
to
do
play,
and,
accordingly,.
If
suddenly-
and
every
time
we
will
swim-
takes
a
break,
deploy
this
contract
at
this
address.
A
If
we
want
to
suddenly
start
a
clean
slate,
we
can
specify
the
key
minus
f
force
when
he
creates
accounts
for
perry
and
for
heat
and
at
the
new
address.
You
can
also
do
it
yourself.
If
the
question
is
delete
which
folder
is
not
rdf,
that
is,
if
the
paths
disappear,,
then
it
will
also
be
perry
created
by
our
deputy,.
The
files
are
usually
stored
in
a
folder,
but
a
slash
with
mayonnaise,
that
is,.
A
If,
for
example,
you
need
this
file,,
you
can
take
it
just
like
the
court
will
offer
a
crochet
have
so
that
everyone
can
make
sure
that
your
file
matches
its
hash,
because
the
radiation,
respectively,
people
can
without
not
having

This

simply

for
us
to

If
your

requires

then
we
can
specify
it
to
specify

our

we
want
to
offer,
and
also
not
for
the
sake
of

if
this
is
required

so
that
if
you
do
not
have
a

loaded
application,
if
you
just
update

Probably
the
best

now
to
go
over
it
in
more
detail
means
it
doesn’t

is
what
we
use

use
different
different
methods
inside
themselves,
and
one
of
them
is
this
variable
n.
It
has
a
lot
of
interesting
things
here.
I
wrote
out,
as
it
were,,
probably
the
most
important
thing.
A
That
will
be
useful,
almost
constantly,,
but
we
will
now
approximate
with
the
pop-up
list,.
It
also
means
we
are
importing,
and
this
is
not
just
children
and
engineer
benjen.
You
will
need
used.
M2,
:
and
some
method
example.
N2,
:
and
also
the
deposit
will
give
you
the
size
of
the
tokens
that
the
user
has
applied.
These
operations,
understandable,
replenish
the
balance.
We
must
become
some
amount
in
order
to
somehow
in
spore
contract
pro
to
interact
with
this
transaction
express
on.
We
need
to
learn
m.
A
A
This
is
a
function
that
displays
on
the
forehead,.
We
can
see
it
in
the
console
and
of
course,
first
of
all,
secondly,.
It
can
be
the
entire
block
to
argued
onions,
for
example,.
This
will
be
attached
to
the
transaction,
we
will
look
today.
Managers
can
also
catch
this
log
in
the
error
handler
on
the
browser
side
and
also
somehow
show
it
beautiful
in
general,.
The
bow
can
be
useful
panic
money
team.
It
makes
the
same
log,
but
first
interrupts
the
code,
that
is,.
A
When
an
unforeseen
situation
occurs,,
you
can
reset
everything
that
happened,
get
out
errors
and
be
sure
that
the
smart
contract
don’t
process,
anything
that
was
in
a
panic
is
done,
except
that
only
the
gas
can
be
spent,
because
the
work
has
already
been
done.
It
is
for
the
miners
it
is
paid.
This
is
done
so
that
people
cannot
spam
the
network
with
some
transactions,
all
of
which
are
reset
so
that
the
miners
do
not
died
under
load.
A
A
Then
the
method
calls
the
next
method
that
calls
the
next
method,.
Then
in
this
case,
the
process
for
the
sake
of
it
will
be
the
same
person
who
was
originally
this
method
a
summer
account
de
may
be
different,
depending
on
where
who
calls
the
method
along
this
chain,.
Today
we
are
attentive
and
see
what
else
can
be
to
be
important
means.
Well,
everything
is
in
the
contracts,
some
sources
for
it
to
grow.
We
have
some
sources
for
randomness
you
can
take
and
make
the
coverage
random.
You
can
check
whether
this
account
is
valid.
A
You
can
look
at
the
height
of
the
blockchain
once
yes,
that
is,,
what
block
is
currently
located,,
but
if
you
have
some
I
will
tell
you
how
long,
then
you
can
see
either
the
times
there
of
the
block
or
the
height
of
the
block,.
Let's
say
you
want
the
books
to
have
the
courage
to
work
only
when
the
blockchain
reaches
some
income
block
number
large
for
round
or
whatever
you
can
do
it
using
these
same
variables,
well,.
A
As
for
the
promise
of
mine,,
let's
analyze
a
little
later,
we
can
see
how
the
previous
call
to
some
function
was
executed,,
where
to
which
control
was
transferred
to
us,.
How
many
cubes
were
called
previously,,
what
was
returned
and
so
on,
we
can
work
with
the
state
of
the
contract,.
It
can
be
dangerous
to
overwrite.
A
A
But
I
personally
leave
a
link
to
this
site
here
with
a
description
of
dogs,
rice.
rain,
.
I
visit
all
the
extra
children
every
day,,
something
here,
I
see
for
you,.
This
is
also
useful
from
the
indicated
type
that
may
be
useful
to
you
and
too
large
numbers
to
be
processed
correctly
by
javascript.
We
wrap
it
like

This
is

We
trained
worked
with

but
if
you

you
are

These
are
huge
huge

of

If
you

to
the

to

A
Just
didn’t
understand
that

are

so
we
send
it
as
a

A

so
that
the

it,
I
won’t,
lose
it
for
you,,
but
it
will
give
you
not
to

but
it
will
give
us
before
us,
as
you
can
also
see
the
number
here,
take
all
sorts
of
things
and,
in
general,
see
how
you
do
what
to
do.
Here,
again,
here
are
these
methods
which,
by
the
way,
it’s
time,
to
talk
about
these
methods
of
data
structures.
A
Article
into
Russian
about
data
structures
that
are
used
in
contracts,
the
world
of
anton
romanko
v
did
it.
He
got
his
prize
will
get
50
problems.
I
asked
to
make
an
example
and
how
we
can
use
different
data
structures.
Let's
read
what
anton
told
us
and
with
some
of
my
comments
in
the
last
video
we
did
it
at
the
end.
You
can't
use
data
at
random.
You
have
to
understand
what
structures
there.
A
Was
a
lot
of
information
about
what
and
why
and
what
is
used
about
it,
and
yesterday
it
was
just
told
to
see
if
a
friend
missed
it.
If
you
suddenly
make
a
mistake
in
the
design
of
data
structures,,
then
it
can
be
very
painful
for
you.
First,
there
will
be
problems
with
the
contract.
Second,
you
will
have
to
rebuild
the
contract
on
the
go.
It's
not
as
much
fun.
We
'll
do
it
in
the
next
next
video,
so
it
means
that
he
made
himself
become
a
structure
vector
more
than
once
children
collections,
vector
means.
A
Reassembling
elements
is
expensive
for
gas.
In
this
structure,
you
can
store
access
data
that
we
get
through
yandex,
for
example,
if
you
have
some
striking-
and
we
want
you
to
know
in
what
how
much
income
we
received
in
each
cycle
in
turn,
this
is
you
technician
we
can
use
a
vector
in
this
case.
We
will
need
to
know
the
indices.
Just
take
the
desired
value.
A
You
can
change,,
add
and
remove
some
values,.
You
can
run
through
the
vector
itself,.
The
fact
that
these
si
vectors
are
implemented
automatically
makes
it
more
expensive
to
use
this
vector
specifically,,
probably
in
the
example
from
the
rating,.
If
I
understood,
the
prime
correctly,
I
would
probably
use
it
rather
recipe,
but
let's
for
now
like
this,
so
this
idea
in
principle,
it
can
also
be
used
here.
A
We
can
probably
somehow
calculate
all
the
incomes
of
the
stay
king
pro
for
the
vector
by
going
through
them
ourselves
next
door,
but
for
now
we
can
do
the
operation.
But
of
course,
ideally,
we
just
have
to
have
separate
values,
separately,
which
digit,
which
will
increase
each
time
we
b.
Let's
know
the
value
for
each
day
and
the
total
values
in
principle,.
This
should
be
enough
for
you.
It
is
not
advisable
to
resort
to
a
vector
to
take
its
amount.
It
was
easier
to
save
each
time.
A
Look
up
set.
Suppose
our
contract
is
stored,
a
list
of
registered
users.
This
structure
is
suitable
for
us
to
cheaply.
Add
new
accounts
collection
appears
whether
we
register
a
user
or
not,
yes,
I
agree,.
This
is
a
cool
thing
and
we
can
add
users
each
time,.
Then
we
can
understand
that
we
have
views
there,.
What
methods
we
have
in
the
lookup
network,
we
can’t
run
through,,
we
won’t
be
able
to
pull
out
all
registered
users,
in
principle,.
A
She
is
a
recipe,
although
I
removed
my
example
for
them
there
was
too
complicated
an
example
she
shakes
at
can
be
useful
to
us.
If
we
for
example,,
we
allow
in
in
our
contract
to
work
only
with
some
set
of
tokens,,
and
let's
say
when
a
user
comes
to
us,.
We
check
the
deceased
to
apply
this
and
if
this
token
exists
in
our
network
address,.
If,
for
example,
it
has
a
content
field,,
we
allow
it
in
the
transaction.
If
not,,
then
we
say
sorry
what
it
was,.
A
Only
we
don’t
need
it
at
all,,
but
at
the
same
time
we
need
to
get
a
certain
value
of
all
allowed
tokens.
They
know-
and
there
can
be
many
where
the
user
is
used
in
principle
door
to
know
what
is
generally
available
in
the
contract,.
This
should
be
a
method,,
so
we
can
use
it
in
this
if
it
is
an
arter
color
and
then
somewhere
on
the
screen,
beautiful
walls,
we
can
display
a
list
of
supported
points
as
a
vector
you
can
just
go
over.
A
Look
at
me
quite
often
hints
and
will
use
this
contract
to
this.
For
some
structure
without
key
operations
we
must
know
the
key
in
advance
can
be
used
as
a
contract.
That
stores
the
balance
by
id
by
the
user
fully
agrees
a
good
example.
We
have
a
list
of
balances
and
for
each
user
we
can
get
his
own
balance
in
principle,.
We
are
not
very
interested
in
some
kind
of
list.
We
have
a
user
of
everything
available.
We,
the
main
thing
for
each
user,
is
to
get
his
balance.
A
While
here
I
have
a
good
example.
More
additional,
let's
say
that
we
need
to
store
a
balance
and
for
each
tokyo
there
should
be
a
user
a
certain
token
and
a
balance,,
presumably
that
the
user
can
have
a
balance
and
at
different
points.
Here
we
have
it
in
this.
It
echoes
with
these.
It
will
store
a
list
of
allowed
tokens
a.v.
A
how
to
store
the
balance
for
us
and
we,
well,
that
is,
in
fact,.
There
are
three
variables
here
when
there
should
be
an
account,
go,
find
the
currents
and
the
balance
is
a
pretty
good
method
to
do
this
way
and
stm
a
separate
structure,
token
buy
account
where
we
have
an
account
this
person
and
the
account
token.
These
are
a
contract
about
the
movie,.
A
Then
we
create
a
lookup
map
and
we
will
use
this
very
talking
account
as
its
key,
that
is,
due
to
the
unique
serialization,
the
values
\u200b\u200band,
will
not
be
repeated
there,
and
the
balance
will
be
the
own
value
for
this
case.
In
this
entry,,
the
user
will
come
and
say
what
balance
I
have
for
such
a
token,.
We
can
easily
create
it
in
such
a
structure
and
ask
for
a
balance
for
it,.
This
will
work
very
quickly
and
is
very
effective,
in
principle,
to
what
is
needed
on
orders.
A
T'mek,
here
is
Anton's
player
for
some
game,
for
example,.
We
have
a
task
that
we
1
day.
We
pay
a
reward
for
killed,
enemies,
respectively,.
We
can
record
apparently
rewards
and
at
the
same
time
we
can
then
go
over
all
the
we
will
find
an
award,,
let's
say
the
person
who
received
the
most
awards
and
give
him
an
additional
prince
bonus
or
just
bring
him
to
the
leaderboard,.
This
is
an
important
task
for
this,.
A
It
may
well
be
used
pert
map,,
but
even
then
it
will
be
more
expensive
because
we
can
also
use
these
methods
here.
Iterations
here.
It's
all.
We
have
methods
that
we
can
do.
We
can
take
values
separately
by
keys
separately,
run
through
values.
we
can
clear.
Can
we
can
bring
all
this
to
the
rector?
Well,
of
course
we
can
add
and
remove
a
value
you
can
check
whether
it
is
empty
to
take
its
length.
A
That
means
again,
let's
look
at
an
article
about
these
methods
about
these
types
of
data.
Plows,,
we
should
pay
attention
to
quotation,
runs
here,.
We
should
try
to
use
those
data
structures
that
do
not
use
linear,
or,,
even
more
so,
logarithmic
complexity,,
that
is,.
If
this
is
done,,
this
will
help
us
get
away
in
China
limits
very
fast,
because
I
say
out
on
since
there
will
be
a
base,
users
began
to
grow
and
complexity
will
grow
mike
sooner
or
later
we
will
break
all
the
barriers.
A
So,
ideally,
we
should
think
of
our
data
so
that
they
have
these
ooo1.
The
simplest
complexity,
great,
let's
move
on
at
the
end,
I
will
answer
all
the
questions
promise.
This
was
asked
in
one
from
the
video,
and
today
we
will
talk
a
lot
about
drawing,.
Let's
look
separately,,
it
means
they
have
their
own
promises
and
they
use
cases,
firstly,.
If
we
need
to
return
a
certain
promise,
for
example,,
we
are
doing
a
learning
transaction
code,.
We
should
basically
know
what
else
is
going
on
there,
then,
whether
it
failed
or
whether
it
was
executed,.
A
What
is
there,
yes,
like,
that
is,
a
black
box
is
returned,.
Here
we
get
this
case,,
then
we
are
such
a
kind
of
synchronous
call,.
We
sent
a
transaction
and
it
comes
to
us,.
We
process
the
answer,.
This
is
a
question
and
did
what
next,
a
screwdriver,
we
can?
How
want
to
catch
the
issue,
execute
the
next
action
along
the
chain
on
the
side
of
the
own
prom
blockchain
ise
will
help
us,.
We
need
to
complete
a
series
of
transactions
inside
some
kind
of
wrong
place,
for
example,.
A
Here
you
can
see
again
on
this
site
that
I
already
advertised
to
you
today,.
This
can
work
firstly,.
We
can
return
a
promise
in
this
case,,
a
video
from
them
and
contract
and
methods
and
another
contract.
We
can
call
control
this
method
from
this
contract
b.
Some
thread
method
with
parameters
and
what
will
return
there
send
to
exit
from
contracts
reiki
2
use?
We
can
make
these
members
run
one
again
in
their
account.
We
pass
the
same.
We
add
an
access
key.
A
We
need
to
do
from
exactly
in
this
sequence,
not
earlier
and
not
later,
therefore,
apart
from
here,.
It
works
ideally
for
such
values,
I
have
such
uses,.
We
can
set
different
methods,,
we
can
see
work
with
keys,,
you
cry
promise
and
we
can
make
some
kind
of
zen
very
useful,
useful.
Not
that
again
what
kind
of
fasten
you
we
do.
One
thing,
then
we
immediately
do
another
decided
to
do
in
Samarkand,
as
you
understand,
that
is,
for
example,,
we
can
always
see
4
accounts
in
this
sequence,.
A
If
suddenly
we
write
than
just
1
to
23,,
then
in
fact
we
don’t
know
and
it
won’t
be
executed,.
Maybe
something
will
happen
on
one
of
the
notes
not
sticks
by
design
and
I
fail
for
a
long
time
will
be
executed
later
or
a
general
recipe
for
the
whole
wildly
vouch
for
use.
Quite
often
in
our
work
to
follow
the
order
of
actions
with
the
ritter.
A
We
can
see
and
return
the
promise
as
a
certain
value,
although
it
is
written
here
that
to
is
identical
to
a1
and
a2
and
what
else,,
but
we
can
use
all
sorts
of
methods
for
converting
for
casting,.
We
can
do
in
the.
If
we
need
it
completely,
then
I
hope
it
will
be
clear,,
well,
yes,
it’s
clear
that
their
promise
died,.
They
work
this
way
in
Russia,
because
we
have
other
sequences
in
a
different
way.
A
lot
no
need
to
transfer
gas.
A
If
you
make
a
chain
of
promises
of
this,,
you
will
have
to
apply
gas
there,
well,
today,
we’ll
see
with
you
the
main
thing
for.
Why
are
we
propolis
and
saying
this
to
talk
about
the
growth
of
contract
interaction?
This
is
probably
the
biggest
and
most
important
thing
that
exists
in
blockchain
development.
Now,
since
we
can
work
with
any
contracts,
it
would
be
a
teaching
as
if,
like
the
moon
and
pr.
A
This
is
quite
an
interesting
topic
for
a
couple
of
minutes:
I’ll
chat,
that
is,
imagine
that
you
again
have
some
kind
of
appstore
or
google
play,,
but
you
can
work
at
the
program
level
in
this
google
play
with
any
contract.
That
is
with
any
application
that
is
in
this
google
play,
let’s
say
you
play
on
the
angry
birds,
computer
or
what
yes,
and
for
example,.
You
have
some
sort
of
schedule
there
like
a
diary,
and
you
can
ask:
how
much
are
you
today
playing
Lego,
Angry
Birds
or
how
much
who
did
he
follow
value?
A
How
else
what
happened
like
all
the
contracts
that
work
there?
They
have
some
kind
of
open
methods
and
any
application
can
work
with
them.
Most
of
all,
this
is
correct,
and
best
of
all
this
is
manifested
by
the
fin
ans
applications,
that
is,.
Let's
say
we
have
a
certain
contractor
and
an
application
that
gives
loans
to
gopniks
landing
on
the
security
of
something
not
Kiev,.
A
Some
kind
of
continuation,
for
example,
does
trading
on
the
exchange
of
legs,
of
operations
on
the
exchange,
waiting
for
nicknames
exchange,
and
for
example,
3
applications
make
insurance,
for
example,
a
very
distant
deposit,
not
like
insurance.
We
pay
the
amounts
and
some
case
is
insured
for
us,.
So
we
can
use
these
three
methods
that
we
came
up
with
from
the
main
ones
from
the
application
that,
let's
make
a
code
from
a
raid
on
other
people's
money,,
they
use
your
money,.
Let's
say
you
make
a
loan
secured
there,.
A
Then,
let's
say
you
immediately
insure
your
deal
and
send
it
to
the
exchange
antenna
to
do
some
kind
of
leveraged
operation
and,
for
the
most
part,.
This
is
all
cross-contact
interaction,.
This
can
all
be
done
on
the
blockchain,,
and
this
is
exactly
what
makes
Dafa
Dalek
heard
the
letter,
combinations
of
decentralized
finance
Dafa,
in
fact,
only
due
to
this
chip,
and
it
went
from
the
comp
scored
here.
Interoperability
when
some
connection
some
things
mentioned,
can
be
interconnected
to
give
new
ones
from
cases.
That,
in
principle,
were
not
even
intended,.
A
They
were
not
written
for
the
sake
of
this,.
We
can
do
this,
outside,
cross-contract
interactions
work
through
a
macro
contract
text,,
let's
again,
I
will
open
the
page
here.
Myself
theories
are
indicated
for
the
script
symbol,,
probably
soon.
This
will
manifest
itself
for
growth,.
We
will
now
talk
about
write
in
more
detail
the
code
for
the
cross
contract
for
interaction,.
It
means
that
the
important
point
here
is
that
all
calls
are
synchronous,.
A
This
is
what
distinguishes
it
from
other
members,
that
is,,
when
we
do
some
kind
of
crosscontact
on
interaction
it
can
be
performed
not
in
this
block
that
we
started
working
in
the
next
flesh
or
through
the
block
at
any
time,
that
is,,
so
that
mom
does
not
collect
all
the
calls
in
one
block
and
the
mind
does
not
process
just
because
of
this,.
It
happens
in
other
scientists,
too
called
kanzashi
congestion.
When
too
much
is
taken,
it
gathers
in
a
heap,
then
can't
collide
I,
have
it
all
working
synchronously,
respectively,?
A
If
suddenly
we
need
to
return
in
stock,
you
have
a
certain
method.
We
called
a
certain
contract,
another
contract.
We
want
to
return,
we
can
no
longer
before
it
becomes
gone
to
become
with
the
past.
We
need
to
re-
call
our
own
contract
to
transfer
some
data
again
to
see
what
actually
happened
for
some
time.
Something
could
have
happened
differently
to
perform
new
actions
accordingly,
of
course,.
This
requires
increased
gas
consumption,,
but
there’s
nowhere
to
go,
it’s,
not
so
much
that
it’s
just
to
go
crazy
for
you,
no
less
to
bear
in
mind.
A
There
will
be
more
serious
losses
in
gas
and
what
is
important
is
these
flasks
that
are
returned
to
us
from
the
contract
that
we
will
pull
the
hatch
for
the
sake
of
something
they
should
be
private.
They
should
have
access
only
to
the
smart
contracts
itself.
This
is
done.
Keep
in
mind
a
piece
is
always
open.
Some
then
the
contract
may
begin
to
pull
your
strawberries,,
no
matter
how
bad
faith
it
may
be.
A
Some
contract
can
just
start
returning
you
a
hundred
amount,
and
if
you
don’t
check
someone
actually
called
this
for
this
record,
you
can
start
giving
money
it’s
not
wrong.
It
should
be
straight
to
us.
Often
we’ll
see,
and
so
this
is
how
we
implement
it.
All
let’s
I
now
try
to
write
some
code
that
will
work
for
us
with
the
non-commissioner
already
familiar
to
us,.
This
means
here
is
our
contract,.
I
have
now
compiled
a
new
completely
new
branch,
I
want
to
make
such
a
code,.
A
We
will
have
two
different
balls
and
we
will
make
one
counter
as
it
will
be
the
main
counters
and
we
will
make
it
so
that
2
counters
cannot
be
added
if
the
value
of
the
first
counter
k
is
less
than
the
value
of
2
counters
and
then
a
little
more
play
with
all
this
8
enough
time,
let's
mean
for
n
At
first,.
We
will
run
this
example,
which,
using
the
second
lesson
in
the
last
lesson,.
We
will
just
do
now,.
Let's
do
not
yarn
build,.
You
will
re-assemble
this
contract
with
us,.
A
It
will
be
like
such
an
immutable
sample,
and
we
will
do
the
second
one
soon,
with
the
contract
to
the
first
contract,
and
so
so.
I
do
not
rdf
diploma
minus
f
I
do
force
update
it
to
a
new
address.
Now
we
will
create
only
a
new
contract
from
ends
at
593
well,.
Let
me
write
down
yar
put
on
and
now
run
its
front
end
of.
A
A
Now
we
all
happened,,
why
got
off
some?
We
launched
our
content
on
in
the
park
that
we
already
used
before.
We
already
have
local
storage,
some
values
,
but
this
is
wrong
because
we
don’t
describe
any
keys
for
this
contract
syvali
now
on
it
should
work.
We
should
get
one,
we
actually
everything
works,
fine
for
us
12.
Now,
let's
open
our
contract,
which
is
a
new
new
contract
counter,
and
we
will
try
now
to
make
interaction
with
the
first
contract.
First,
we
need
to
import
the
contract
text
here.
Further.
We
will
have
to
here
create.
A
Not
the
most
convenient
copying,,
so
we
create
some
kind
of
such
method
and
you
see
what
we
have
created
here.
We
are
making
some
new
counter
value.
We
are
creating
a
data
structure
external
counter
and
we
will
take
the
get
method
from
it
to
us,
that
is,.
If
we
wanted
to
take
when
other
methods
from
external
to
this
example,.
A
If
we
have
then
remember
that
the
user
was
bitten
now
in
the
enemy
no,,
we
can
go
in
shock
from
users
or
something
else
or
some,
then
the
measures
that
we
want
to
run
in
another
contract
as
we
see
it,
get
we
have
no
more
parameters.
So
we
just
self.
If
u,
as
there
were
parameters,,
they
can
also
be
registered
here
to
know
what
method
we
will
need.
A
A
Beria
equals
commander,
get
number
and
write
some
kind
of
assert
here
to
check
whether
it
is
any
value
at
all
and
whether
it
is
greater
or
less
than
our
current
value.
0.
The
approach
is
wrong,
because
this
is
not
a
value
for
us,,
but
this
is
what
we
say:
promise,
that
is,
in
this
case,
the
document
will
not
work,.
We
do
not.
We
can
equate
some
value
to
this
call
because
it
will
be
executed
somewhere
in
the
future,
and
we
cannot.
We
will
return
to
this
matter
back
in
the
past
here.
A
Our
correct
approach,
which
we
need
here,
is
something
like
this.
You
will
have
to
call
this
method
indicated
here
the
address
of
the
contract
that
we
want
to
call
yes
here
the
contract
started
which
I
just
for
heat
or
two
bodies.
Here
we
call
this.
We
launch
this
path
somewhere,,
we
would
apply
gas
and
tokens,,
but
we
just
don’t
need
it,,
and
after
that
we
launch
some.
A
Other
method
in
our
contract
with
the
zen
method,,
which
will
actually
respond
to
what
we
get
from
this
blogged
to
us
bora,
we
sent
a
kit
set,
we
processed
and
we
returned
so
here.
I
have
such
a
method,
you
see
it
get
to
us
and
it
no
longer
has
a
count
but
xl
here
now
it
will
be
possible
to
write
the
same
thing
only.
It
will
not
be
a
counter
and
it
will
be
here.
We
have
x,
selfies
of
collapse,
the
whole
name.
You
can
interrupt
to
write
your
own.
A
This
is
not
a
dogma
to
the
point.
The
main
thing
is
that
everything
is
simple
for
you
struggled
and
so
here
I
will
write
that
we
will
need
a
method
that
we
call
it
get
to
us,
that
is,
when
we
call
it
in
the
case
when
we
run
out
of
get
number
and
exit
here
there
is
a
parameter.
We
pass
here
call
back
on
some
value
to
us,
because
that
we
need
to
return
this
value
here
and
process
it
in
our
own
contract,.
A
So
here
we
get
to
see
we
pass
and
to
run
the
callback.
We
need
the
same
three
parameters,,
but
here
we
indicated
the
specific
contract
that
we
want
to
pull
in
this
case
when
it
happens
already
return
because
of
our
call
back
to
do
is
the
function
with
which
it
requires
a
return,.
We
will
indicate
here.
A
Our
contract,
in
fact,
here
is
the
king
of
this,.
Our
contract
will
come
out
that
is
running,
again,.
We
can
indicate
it
in
direct
form,
direct
text,.
This
is
more
reliable
so
that
there
is
nothing
to
print
indicate
in
t
.To..
We
will
return
our
contract
and
give
it
0
tokina
525
strictly
for
in
order
to
somehow
process
what
actually
happens
here.
A
Let's
copy
the
value
I
will
copy
the
functions
very
much
and
which
we
will
process
this.
Very
he
get
number
means
again.
Ladies.
We
use
the
newt
method
was
sat
in
because
that
we
will
change
the
alphabet
than
we
write
about
it.
This
is
about
what
I
was
talking
about,
because
we
want
only
our
contract
boo
to
be
able
to
call
this
call
back.
A
If
suddenly,
another
malicious
contract
comes
to
call
this
call
back
in
itself,,
then
we
will
not
launch
it
because
what
he
will
have
in
this
case,
it
can
be
written
in
a
more
explicit
form,.
By
and
large,
we
can
compare
the
account
carat
diy
account
processor.
If
this
is
on
the
account
and
this
one
works
for
us,
especially
that
this
method
was
to
manifest,
it
is
just
doing
it
to
simplify.
It
means
our
method,
9
-th.
A
We
check
whether
this
is
the
value
that
we
received
from
the
callback
and
is
greater
than
the
value
that
is
in
our
contract
and
e
If.
This
is
not
so,,
then
we
ask
you
to
first
increase
the
counter
that
we
had
in
the
first
contract,.
Otherwise,
this
contract
does
not
come
off
for
us,.
We
go
further
here
and
call
a
regular
flight
for
this,
it’s,
just
a
miracle
copied
well,
and
here’s
an
important
thing.
Why
I’m
asking
you
today?
I
want
this
method
to
return
me
to
sell
it,.
A
A
A
Completely
not
roar
check.
Suddenly
he
took
me
some
old
value
that
there
was
no
unnecessary
state.
Yes,
he
is
not
for
the
old
value.
Let's
also
I'll
quit
right
now.
I,
don't
want
to
work
with
about
the
old
contract,.
I
will
make
a
non-
virgin
diploma
minus
f.
It
will
create
a
new
contract
for
me
for
hiv.
949
and
I
had
zero
28
years
here,
a
new
contract
so
that
I
would
not
use
some
old
state
that
I
used
when
preparing
kuroki
for
the
lesson
and
I,
let's
run
obviously
dev.
A
He
it
will
overwrite
the
question
again
so
that
the
behavior
is
more
predictable
and
raise
the
frontend
for
us,
okay,.
So
we
suggested
continuation
in
this
one,.
Now
we
log
in
again-
and
our
first
contract
has
a
value
of
2,.
Let's
immediately
deduce
from
the
salt
so
that
we
can
see
what
is
happening
with
us,
so
the
first
time
I
run.
If
we
they
didn’t
mess
up
anything.
If
I
didn’t
mess
up
anything,,
then
it
should
work
for
us,
but
from
the
street
and
the
second
time
somehow
the
mascot
was
written.
A
A
See
our
last
famous
field,
method,
respectively,,
you
see
implement,,
we
made
a
call,,
they
called
a
local
clement,
after
that,.
Our
contract
went
to
call
us
somewhere
from
the
contract
that
we
asked
to
see,.
We
got
the
value
2
in
response,
because
this
is
what
is
now
in
the
contract
and
after
that
we
had
an
error,,
see.
Please
add
first,
the
next
only
the
first
counter.
Only
then
2
is
added,
that
is,
everything
that
we
wrote
works,
no
wonder
box
1
of
the
code,
where
you
tell
me
so
now,
let's
run
the
first
counter
again.
A
See
this
with
a
meter,,
maybe
two
longer
finalizations
are
required
here,.
We
first
do
one
thing,
then
the
second
then
the
third
one
else
it
will
work,.
Then
you
will
start
to
work
which
should
initially
work
badly,,
because
sometimes
before
it
collects,
as
it
were,
perry,
send
transactions
to
3
sought
to
worked,
which
is
logical
as
well.
Here,
4
5,
it
doesn’t
work
because
we
wrote
the
code
so
that,
while
this
counter
is
not
being
treated,,
this
counter
2
of
yours
will
not
work
because
it
actually
interfered
with
the
error,.
A
Let's
make
a
simple
error
handler
so
that
we
do
not
have
to
look
at
the
console.
Since
our
increment
method
returns
sagging,,
we
can
easily
find
out
on
the
india
front
what
is
happening
there
with
this
method,.
Although
I
would
have
a
demand
to
write.
It
means,
let's
write
the
quality
applied
food
that
mulan
cut
exception.
Let's
what
we
do
do
console.log
this
is
the
exception
itself.
A
A
A
Us
in
contra
jacket
with
found
it
did
not
change.
The
frontend
should
now
restart
it's
65
to
91.
How
did
I
mess
up
something?
Yes,
apparently
gay.
Let's
try
to
do
it
again
for
logging
in
maybe
and
the
pierburg
console.
So
just
like
that
I
go
in
now.
Let's
go
to
our
delle
portal.
Look
at
the
console.
We
have
a
C
grade,
that's
right!
A
If
I
press
the
plus
now,,
then
the
four
should
work
for
us,
an
alert
should
not
appear,
and
actually
something
like
this
should
appear
more
beautiful,,
because
error
has
appeared
for
us
and
we
no
longer
have
an
error,.
It
is
with
you
the
console,
that
is,
we
can
catch
this.
This
output,
this
this
input,
value
and
somehow
beautifully
process
it
and
display
an
example
to
users
in
the
form
of
someone
softer
error
message
to
return
us
now,
not
a
promise,
but,
for
example,
a
value
of
true
or
false,.
A
A
It
means
that
in
this
method,
it
is
itself
7,
that
is,.
It
is
a
kind
of
call
back
that
returns
us
after
the
operation
of
the
samsung,.
What
am
I
doing,
I
check.
It
means,
firstly,
whether
this
method
will
become,
that
is,,
what
it
has,
in
addition
to
cutting
off
the
scout,
is
units
of
it,
someone
returned,,
not
just
called
it,,
but
someone
returned
it,.
This
is
a
very
important
point,
here,
and
then
I
check.
What
was
the
trial
cut
off
from
the
previous
call,?
The
mother,
again,
I
need
to
import.
The
promise
result
here.
A
First,
and
secondly,
I
will
need
to
import
yes,
how
to
describe
the
function
so
that
ours
in
general,
in
principle,.
Our
smart
contract
knows
that
we
have
such
a
new
function.
Now
that
we
can
be
processed
now
in
this
case,,
it
means
that
if
we
call
this
inside
mend
the
app,,
it
will
work
for
us,.
Then
he
himself
will
come
here
and
we
will
eventually
get
true
or
false
as
a
result,.
Let
it
work
for
us
if
the
fall
worked.
A
A
If
you
are
where
I
am
their
financial
application,
then
believe
me,
especially
if
you
published
the
code
in
github,
it
will
be
a
very
clever
piece
to
look
for
how
you
can
illegally
call
your
strawberry,
pretending
to
be
your
application
so
on
this
I
have
on
the
topic
of
this
lesson.
We
all
looked
at
a
lot
of
advanced
techniques.
In
now,
let's
be
happy
to
answer
your
questions.
Exception
handling
like
children
in
a
cone,
as
it
were,
on
bread,.
It
turns
out
as
far
as
told,
in
principle,
you
can
return
like
a
pipe.
A
A
So,
let's
then
ask
questions:
I
go
to
the
detective.
A
young
block
is
stored,
a
block
of
reading
or
something
it
costs
for
a
contract
or
a
user
forehead
is
stored
in
special
archival
waters
and
is
deleted
over
time.
It
is
not
stored
in
communication,
but
it
is
shown
in
the
explorer.
It
is
not
planned
that
the
logs
will
be
stored
forever.
It's
just
no
information
where
you
can
look.
What
do
you
want
to
see
in
the
process
of
working
with
applications,
I’ll
ask
Alex
with
thanks,
good
question,?
A
Then
we
can
interact
with
other
contracts
only
for
reading
and
for
writing,
too,.
If
for
writing,,
then
the
transaction
will
be
divided
into
several
blocks
yes,
we
can
interact
with
writing,
that
is,.
We
usually
do
this.
The
transaction
just
calls
it
the
contract,
they
p
user
contract,.
It
can
call
something
done
with
another.
Contract,
then
return
your
contract,,
but
on
the
condition
it
was
done,
of
course,.
If
they
give
access
there,,
it
will
record
a
small
example
of
how
it
works,
sometimes
Kalmyk
data,.
Let's
say
we
want
to
withdraw
a
certain
token
from
our
contract.
A
Back
to
the
address
on
the
wallet,
the
user
of
the
token
I
am
opponents
between
them,.
You
were
like
that.
Yes,
there
is
a
kit
of
oil
or
something
else,
well,.
Let's
say
3
years
talking,
which,
to
move
it,,
you
need
to
call
someone
a
contract
for
a
fantagiro
tariff,
ti,
lower
shabby
transfer,
that
is,
we,
for
example,.
How
we
do
we
say
to
a
person
there
is,,
let's
say
one,
yes
and
or
one
of
the
children.
We
say
we
want
this.
One
see,
send
him
to
his
balance.
A
We
and
reduce
his
balance
on
our
contract,
get
up
30.
After
that
we
call
the
transfer
to
go
with
this
one
as
an
argument
and
check
whether
they
came
really
talking
or
not.
Then,
all
of
a
sudden
what
-something
happened,
not
at
all
suddenly
for
how
the
problem
is
yes
or
suddenly,
the
indicated
cards
are
not
correct,
a
specific
address
or
suddenly
a
contract
for
barter.
A
If
we
receive,
after
that,
the
answer
that
rocky
has
come
to
me,
we
take
and
set
the
bar
for
this
person
again
on
back
to
one
so
that
in
the
case,
when
the
photo
is
repaired,
he
can
recover
the
balance
use.
If
we
do
not
do
this,
then
the
person
will
remain
in
case
of
error
just
with
zero,
which
is
wrong.
But
of
course,
this
contract
for
sending
tokens
will
work
if
it
is
from
the
socket
to
the
correct
one.
The
person
has
really
chiseled
everything
works,
and
so
on
that.
A
This
is
about
this
notation
overlaps,
pap
fn
for
functions,
yes,
it’s
a
little
different.
If
you
don’t
write
pap
before
fn,
then
in
principle,,
the
cup
won’t
work,
because
it
won’t
find
it
I
won’t
be
able
to
find
it
some
contract
to
call
it
a
fanfan
bus
private.
It
works
as
if
it’s
right
here
wrong.
Just
minced
heaven,
dad’s
registration
works
only
for
contract
laptops
that
works
directly
in
one
block.
A
A
Often
I
don’t
have
time
for
this
anymore
and
so
right
off
the
bat
I’ll
probably
be
able
to
figure
out
good
examples.
Let’S
try
to
sort
it
out
here
means
the
questions.
Let
me
copy
it
now
so
that
the
reader
can
see
some
specific
cases.
A
few
questions,
so
another
question
from
the
same
person
an
anonymous
from
india.
How
to
delete
a
contract
with
a
great
aesthete
show
an
example
well,.
You
can
just
delete
an
account
with
these
contracts.
A
If
you
want
all
the
whole
shame
to
leave
if
they
don’t
share
an
account,
look
at
the
design
and
you
can
rewrite
this
contract
it’s
worth
rewriting
with
the
help
of
migration.
This
is
also
possible,
in
fact,.
The
main
thing
is
just
to
comb
through
previous
stands
and
start
to
burn
its
1
empty.
Is
it
here
you
just
spears
write
down
the
contract
where
it
will
be
0
costs.
You
will
lose
everything
implementation.
A
Be
eleum
there
or
ilya
asks
in
the
terem.
There
are
events
the
contract
can
generate
a
fountain
sign
went
to
it.
The
tuner
is
not
necessary
to
execute
some
kind
of
proxy,.
We
see
something
else.
It
will
be
additionally
sulfur
with
which
contracts
are
checked
guild
in
china
screw
and
again.
This
is
not
thorium
generates
events
say
it
informs
events.
Yes,
it
is
some
hips.
The
blockchain
itself
will
not
send
anything
to
your
browser.
You
need
to
use
which
some
layer.
A
All
cool
main
thank
you
for
the
lecture.
Ok,
if
there
are
no
questions
healthy
and
have
served
now,
thank
you
very
much
for
your
attention.
If
it
means
you
want
to
analyze
some
specific
examples
in
our
fifth
lesson
that
I
want
to
devote
crawling
just
to
analyzing.
The
application
then
write
your
suggestions
so
far,
I
have
a
plan
to
disassemble
x,
some
big
marketpl
ace
for
needs
and
where
there
will
be
contracts
for
everything
where
there
will
be
a
marketplace.
A
In
fact,
such
a
system
of
auctions
for
buying
and
selling,
and
some
kind
of
frontend
that
processes
all
this,.
So
if
it
suits
you,
don’t
write,
if
you
want
something
special
dmm,
some
prediction
market
we
can
do
it
also
do
choose
what
will
be
the
most
requests
to
the
Internet
me
all,
thanks
and
good
week
to
everyone
until
we
meet
again.
