The
blockchain
is
the
____________________
trend
of
the
moment
.
____________________
has
heard
of
it
but
few
actually
understand
how
it
works
due
to
its
relative
____________________
,
so
we
will
try
to
introduce
it
here
.
The
blockchain
____________________
with
Bitcoin
.
In
order
to
clear
up
any
potential
confusion
,
Bitcoin
is
a
system
of
currency
that
doesn
?
t
rely
on
banks
,
countries
,
or
any
outside
institutions
.
This
is
____________________
a
very
big
deal
,
as
there
are
many
people
living
in
____________________
countries
that
have
to
deal
with
issues
like
hyperinflation
,
not
being
able
to
exchange
their
currency
for
others
,
and
having
to
____________________
currency
on
the
black
market
.
Bitcoin
can
solve
all
that
?
but
the
technology
underlying
Bitcoin
,
called
blockchain
,
is
the
real
star
of
the
____________________
.
Blockchain
is
what
enables
Bitcoin
users
to
be
able
to
exchange
currency
without
any
fear
.
____________________
,
blockchain
works
by
keeping
a
record
of
each
transaction
that
happens
using
Bitcoin
as
a
currency
.
This
record
is
____________________
transparent
to
everyone
and
is
part
of
the
____________________
structure
of
Bitcoin
.
As
Investopedia
puts
it
:
?
To
use
conventional
banking
as
an
____________________
,
the
blockchain
is
like
a
full
history
of
banking
transactions
.
Bitcoin
____________________
are
entered
chronologically
in
a
blockchain
just
the
way
bank
transactions
are
.
Blocks
,
____________________
,
are
like
individual
bank
statements
.
?
This
blockchain
structure
makes
it
very
difficult
to
do
any
sort
of
____________________
activities
involving
the
currency
itself
.
And
indeed
,
its
solidity
is
shown
as
blockchain
is
starting
to
be
used
by
major
banks
____________________
the
world
as
a
way
to
pay
large
amounts
of
money
with
less
time
spent
on
security
,
thanks
to
the
____________________
of
the
blockchain
.
For
example
,

using
