A
Don't
know
much
about
'black
blocks',
but
I
ended
up,
studying
doing
it
in
the
ranch
studies
and
found
11
a
bosco
blog
with
the
explanation
of
what
it
would
be.
The
teaching
that
is
from
shinsei
and
implementing
it
in
python
in
the
link
will
give
a
description
of
the
video
at
the
end
and
I
ended
up.
Reading
it
and
I
was
more
looking
at
the
code,
fully
understanding
that
it
would
be
the
full
blog.
That
is
the
block
that
a
long
time
ago
was
a
lot
in
places
in
the
world.
A
Now
They're
talking
a
lot
of
boxing
in
cape
verde,
with
it's
on
the
attack
growing
a
lot
every
day,
more
and
more
being
worth
a
big
phone
and
block
they're,
so
interconnected
they're,
not
the
same
thing,
but
bitcoin
uses
bloch
tatá
power,
the
guarantee
the
transactions
guarantee
the
movements
bitcoins,
and
that
is
all
that
is
spelled.
So
boxing
is
something
next
to
the
network
that
thing
that
everyone
everyone
knows
basically
is
the
blog
is
a
concept.
A
It
is
a
concept
that
with
you
who
are
the
staff
created
to
be
able
to
store
the
transactions,
inform
that
it
is
traceable.
Nor
that
you
know
the
whole
transaction
of
each
thing
that
happens
anyway.
Many
people
many
places
being
used
in
itself
and
technique
to
deal
with
the
financial
investment
and
everything
else
to
be
able
to
have
this
guarantee.
A
A
I7
is
the
fmi
no
longer
okay,
right,,
but
I'm
going
to
show
a
lot
of
rope
that
I'm
going
to
end
up
showing?
Is
it
working
so
basically,
botín
sports
site
is
not
a
faithful
implementation
of
what
is
used
today,
for
example,
the
bimby
with
that
or
else
in
others
that
have
currency
is
a
good
example.
Shallow
very
easy,
also,
basically
depend
on
box
is
what
is
one
is
a
house
of
blocks
are
rough
from
may,
where
you
structure
it
here
we
have
the
so-called
boxing
block.
The
same
thing
has
an
ex.
A
A
The
prof,
the
proof
and
then
I'll
explain
better
because
it's
useful
for
those
who
have
this
variable
there
and
predicted
rech
is
basically
the
rest
of
the
block
before
this
one,
right,.
The
block
comes
before
or
after
basically,
that's
it
in
the
transaction.
Here
it
's
an
attitude
given
that
we
can
arrive
and
until
then
whatever
in
this
example,
I
created
one
that
only
a
transaction
that
needs
one
in
a
guy
who
sends
a
person
who
receives
the
value,
ready
and
leave
what
you
consider
to
enter
the
room.
A
You
can
try
to
create
something
bigger,
something
different
that
can't
be
just
to
win
or
again
or
I,
don't
know
without
contracts.
Anyway,
you
can
do
these
things
there,
and
here
will
be
our
main
structure.
Let's
go
So
for
the
time,
being,
we're
going
to
try
these
two
teams,,
which
is
the
has
and
negative
occurrence,.
So
let's
go
to
the
implementation
of
this
month
and
the
texture
that
ends
are
basically
what
happens
when
I
create
an
honor
to
be
among
the
great
instances
of
the
block
chances
that
create
we
do.
A
It
will
return
a
notebook
and
a
death
in
with
the
variables
here
inside
it
all
the
voices
in
and
above
all,
start
on
the
1st.
The
first
block
right
and
you
will
find
a
lot.
How
is
james
block
is
like
it
was.
The
first
block
is
that
it
's,
not
your
father
just
returns.
This
little
mouth
creates
a
mutable
variable.
It's
the
director's.
It's
going
to
change
a
lot.
A
So
how
is
it
going
to
be
created
one
by
one
block
or
simply
pass
the
function
here?
This
function
here
is
easy,
right.
It
receives
a
proof
number
of
proof
and
the
previous
hash,
that
is,
at
the
moment
you
create
it,.
Imagine
a
case
that
already
exists
in
other
places,.
Other
blocks
are
already
running
around,.
A
A
The
verification
is
that
this,
if
the
hash,
it
was
not
empty
right
case
like
the
first,
the
first,
the
father
and
all
black
and
empty,
then
there
he
will
pay
and
no
excuse
is
to
check
if
the
assembly
that
the
rest
is
being
sent
is
empty
right.
If
it
is
not
empty
I
do
them.
Is
this
one,
while
the
rest
into
this
variable
rech?
On
the
contrary,
I
wanted
a
new
rech
takes
the
the
last
block.
A
Hence
the
new
block
is
with
the
variables
or
index,
is
the
index
of
the
size
of
who
gives
the
block,
who
is
from
the
blocks,
plus
one
that
the
way
in
my
court
and
watertight
block
takes
what
I
have
at
the
moment
and
in
that
block
takes
the
rest.
Previous
is
like
still
the
that
would
be.
These
people
here
are
the
same
ones
that
offer
this
that
the.
A
A
A
A
A
A
We
carry
out
this
bloch
structure,
making
this
force
this
variable
that
shows
in
the
headquarters
or
server
sound,
and
this
function
here,
the
stream
it
receives
a
structure
equal
to
the
supplementary
claim,
but
it
has
a
credit
that
needs
to
be
implemented.
I
mean
this
simple
one
here
would
be,
there
displays,
it
would
be
logical,
so
basically
salt
would
be
there
and
he
can
get
all
the
variable
that
the
letter
inside
that
he
has.
A
A
A
B
A
A
A
A
A
A
A
It
is
not
changing
and
is
not
understanding.
This
team
for
us
to
do
this
in
what
we
have
to
do
is
mining
the
famous
generation.
That
is
what
we
have
today:
billions
of
ip
voip
computed
with
computers
working
to
be
always
legal
1
to
1,
to
leave
with
2
and
for
us
to
do
this
here.
There
is
not
this
one
that
is
imposed.
A
It
is
called
in
May
practically
there
that
that
or
that
tuf
will
enter
this
people
here
he
is
used
to
be
able
to
do
is
to
have
an
algorithm
called
cash
cash
which,
on
your
farm,
is
not
within
the
scope
of
the
racket,
which
is
basically
one
is
to
have
a
test
that
you
have
to
do
to
be
able
to
get
it
like
this.
In
the
aspect
of
the
video
to
validate
that
block
is
then
here,
in
addition
of
I
have
this
function
here.
A
A
We
are
going
to
do
in
addition
to
this
gay
group
so
to
evaluate
what
this
is.
What
happens?
There
are
several
algorithms
of
several
and
several
other
ways
of
doing
it.
In
an
example,
the
person
does
what
he
does.
He
simply
creates
a
hash
with
the
two
numbers
he
has
is
the
let's
golf
of
the
coup
and
ea
variable
is
running
there
and
it
will
keep
generating
a
hatch
until
the
first
four
digits
is.
The
rest
was
equal
to
zero.
It
will
stay
there,
mining
until
I
get
it.
So
what
is
going
to
happen
here?
A
You
see
here
what
the
people
of
this
in
this,
this
block
iii
in
tribute
or
as
ceni,
come
back
here.
Maine
the
first
to
leave
is
only
you
are
here.
He
made
more
than
35
thousand
interactions
will
protect
and
find
a
hash
there
cute
and
equal
to
4,
with
the
evaluation
helped
the
block,
a
transaction
that
did
it
just
a
little
while
ago,
it's
here,
look
at
the
monster
21.
Suddenly,
an
area
that
was
sent
by
so
this
here
is
the
forged
block.
A
People
go
and
see
here
in
our
block,
it's
2
in
the
first
block.
We
wanted
the
genes
and
the
second
block
this
building
reschke
from
doing
the
city.
2
is
the
hash
of
these.
This
cute
little
thing
in
this
first
block,
and
so
it
goes
if
I
want
to
add
another
transaction
leo
257,
the
Italian
one
that
is
next
to
the
transaction
has
already
entered
in
23.
There
now.
A
A
A
Basically,
this
data
will
be
also
in
these
other
places,
I'm
just
seeing
it
right
here,
for
example,
we
have
two
just
that
12
of
the
edge
here
which
is
resolved
in
two
of
these
two
things
here,
I
want
to
add
one
more
one:
more
boy
to
be
able
to
keep
mining,
creating
new
blocks
that
came
and
everything.
and
if
now
with
a
legal
value
because
I
haven't
tested
it,
then,
basically,
this
is
what
I
'm
going
to
add
to
this
nokia.
We
have
a
new
node
here
at
the
roth
8
thousand
location.
A
A
A
A
B
B
A
A
We
have
to
guarantee
that
all
these
that
all
the
blocks
of
a
block
we
had
in
another
one,
so
this
is
normally
how
it
will
be.
This
is
what
is
considered
a
conflict
is
if
a
drug
in
one
mouth
had
an
owner,
the
new
optimus
has
one
will
variable
blocks
than
the
other.
Then
that's
the
function
of
the
other
car
that
the
guy
made.
C
Items
in
an
initial
moment
have
pity
on
the
team
that
also
competes
the
fall
is
bigger,
and
then
you
have
one
and
then
someone
who
takes
the
family
lived
there
and
ore
new
blog
beauty
right
now.
There's
this
one
here
is
bigger,
so
no
problems.
The
issue
is
just
that
sometimes,
and
you
can
take
226
at
the
same
time
and
the
two
women
new
block
and.
B
C
You
will
have
two
blocks
teens.
The
two
teams
from
the
site
amauri
doesn't
want.
It.
Eni
has
two
little
bags,
one
size
plus
one
you
choose
in
2002
with
the
mineirão
and
the
reward
code
for
2
to
0
in
durban
that
separated
there
is
a
definition
of
how
canonical
that
waits.
For
someone
not
to
like
it
anymore,
then
that
person
they
didn't
choose
to
put
any
of
these
two.
So
I'm
going
to
keep
him
and
two.
B
A
A
A
If
the
can
is
the
content
of
the
block
are
valid
that
basically,
if
he
takes
the
last
block,
takes
the
current
mouth
and
goes
doing
those
checks
from
rech
tv
and
the
proof
of
concept
that
everything
is
right
and
so
on
until
everything
is
finished,
I
'm
going
to
run
this
conflict.
This
conflict
here
for
eight
thousand
nec,
which
is
the.
B
B
B
B
A
A
A
A
So,
basically
guys
this
is
it
I
will
leave
all
these
links
here
in
the
blog
post
will
to
rest
from
this
cut.
That
I
ended
up
doing.
If
the
people
who
know
more
about
the
block
had
to
leave
and
want
to
contribute
to
make
changes
to,
it
is
to
show
them
there
is
an
error
or
better
or
if
they
would
do
it
in
another
way,
it
would
be
interesting,
so
we
increased
it
to
talk
and
she
was
fat.
Altis.
C
D
A
Picture
so
let's
go,
there
is
rocket,
it's
great!
That's
the
name
of
this
one.
This
gentleman,
who
is
very
nice,
very
simple,
to
work
with
anyway
by
default,
he
doesn't
have
it
he
has
implemented.
There
is
his
question
how
to
deal
with
jackson,
but
basically
it
takes
a
library,
another
library
that
the
v
series
and
sound
sound
end
up
working
with
version.
Basically,
so
then
it
is
very
simple
and
your
return
that
you
put
his
attitude
saying
that
it
is
the
return,
will
be
a
waiter
with
the
value
that
is
fine.
A
A
A
Thought
this
little
thing
was
really
cool
anyway,
it's
something
else.
It's
a
way
to
return,
an
error
right
straight
and
what
it's
good
and
what
you
didn't
have
time
to
look
at,
but
I'm
just
going
to
leave
myself
on
the
link
there.
The
site
is
a
dream
site.
Rap
is
easy
and
rocket
point
lol.
Do
you
think
there
is
your
offender.
A
Basically,
that's
it
he's
very
powerful
guy,
very,
very
good.
This
gentleman
who
I
didn't
get
to
implement
more
heavy
things
with
them.
A
blog,
is
something
with
a
template,
but
that
also
has
our
time
frame.
So
it's
very
interesting
to
work
with
it.
I
think,
in
my
opinion,
time
is
the
most
complete
pilot
right
and
for
now
there
is
a
ray
that
is
also
coming
and
is
appearing
a
lot,
but
I
believe
that
what
rock
is
is
still
a
step
forward.
A
A
People
I'll
leave
my
link
there
than
ruby
I,
don't
know
if
karen
the
repô
is
cool.
You
can
get
it
here,
but
anyway,
it's
if
you
find
an
error
here
in
writing.
Test
is
also
good.
Solange
is
very
easy
to
test,
so
you
can
take
this
beautiful
one
here
to
do
a
test.
I
did
it
happens
on
the
ground,
so
see
how
things
go,
but
you
can
handle
this
function
more
here.
It
is
very
interesting.
Is
the
group
from
the
west
it's
big
and
there
should
be
a
scene.
A
A
A
A
Then,
following
it
have
a
rest
and
there
was
only
a
dotcom
stroke,
bauchi
do
dash
br
barra
studies.
There
is
a
series
of
links
that
were
in
the
past
videos,
sé
ea
people
said
try
to
discuss.
Let's
try
to
discuss
new
things
kind
of
study,
a
little
doubtful
there,
's
even
one
thing
that
I
took
that
I'll
have,
with
the
current
one
I
didn't
close
to
that
and
in
the
table.
You
have
to
understand,
because
there
is
someone
who
also
tries
to
solve
this
problem,
then
put
it
back.
