From YouTube: Crypto wallet, much more than blockchain
Description
an online event at Chaintalk
https://www.chaintalk.tv/watch/crypto-wallet-much-more-than-blockchain/
A crypto wallet is not only for blockchain. It is the user agent for using any advanced cryptography technologies in your daily life, and blockchain is just one of them.
In this sharing section, the speaker will share with you what is a crypto wallet, why it is essential, what you can use it for now and future.
A
Hi
hi
everyone.
This
is
Victor
John
from
alpha
Wally,
thanks
very
much
for
inviting
me
to
the
chain
talk
and
today
I'd
like
to
share
with
you
something
about
crypto
Wally,
and
we
will
mainly
talking
about
racing
what
is
the
crypto
Wally
and
why
it
is
important
and
also
working
what
you
can
use
it
for
more
and,
of
course,
them
also
what
you
can
use
it
for
for
future.
It's
a
fused
a
little
bit,
weird
speaking
to
a
screen,
but
I
will
try
to
make
myself
comfortable.
A
So
before
we
start
the
topic,
I
just
quickly
introduce
myself
and
also
our
team
alpha
Wally.
So
we
have
been
working
on
blockchain
that
I've
been
working
on
blockchain
things
that
to
0:11.
So
we
basically,
we
actually
fought
the
Bitcoin
code
three
times
for
different
business
partners
and
after
you
Syrian
come
up.
We
did
a
survey
archetype
work
for
different
Assyrian
product.
B
A
Then
we
joined
the
Commonwealth
Bank,
which
is
the
largest
finance
institution
in
Australia,
so
within
the
bank,
our
CTO
lead
architect
for
those
Bangkok
chain
project
and
also
he
used
to
be
one
of
the
global
archetype
of
our
stakeholder.
So
we
have
a
lot
of
experience
on
infrastructures,
blocked,
replications
and
finance
related
and
more
finesse
related.
So
we
have
a
good
understanding
of
what
is
required
to
using
bulky
to
use
voucher
in
a
real
world
environment
for
for
different
kind
of
applications.
A
B
A
A
Yeah
I
just
draw
a
key,
so
I'm,
using
an
of
course
using
those
keys
to
all
pray,
the
different
kind
of
applications.
So,
basically,
no
matter
what
kind
of
blockchain
related
application
it
will,
it
will
always
require
on
the
user
side.
No
matter
the
user
is
an
individual
is
a
business.
You
always
require
the
user
side
have
a
wallet
platform
which
can
interact
with
the
different
kind
of
cryptographic
protocols.
A
A
Straw
time
and
at
the
end,
because
private
keys
are
still
pretty
important
for
either
it's
a
super
important,
you
should
never
share
it
with
anyone.
So
that's
why
I
draw
a
diamond
at
the
bottom,
so
that
is
the
primary
key,
and
this
is
the
public
key.
So
what
exactly
inside
blockchain,
of
course,
some
informations
we
use
it
as
the
larger,
so
there
should
be
like
a
has
1
ETH
and
the
inside
is
this
piece
of
information.
There's
also
use
a
public
key
information
and
there's
also,
let's
draw
a
private
key
for
minor.
A
A
Public
key,
so
basically
anyone
can
read
this
piece
of
information
and
they
can
cut
the
public
key
information
for
post
user,
a
and
the
both
user,
a
and
miner,
and
with
the
with
the
signature
on
this
block,
they
can
verify
whether
this
block
is
really
signed
by
the
private
key
from
the
miner,
and
by
doing
this
they
can
basically
verify
this
piece
of
information
is
true.
It's
a
very
affordable
and
also
because
it
is
signed.
No
one
can
really
change.
A
A
A
A
So
basically,
this
is
the
very,
very
simple
explanation
of
how
we
use
crypto
wale
with
in
blockchain.
So
basically
is
using
the
private
key
to
sign
message
and
then
broadcast
the
public
key
to
all
the
parties.
And
then
anyone
who
read
the
information
they
can
verify
whether
this
information
is
really
comes
from
the
right
private
key.
But.
B
A
A
P,
can
you
this
private
key
to
decrypt
a
message?
So
basically,
these
are
the
two
fundamental
two
fundamental
functions
of
using
your
private
key
and
public
key
/
and
crypto
only
is
the
software
which,
which
is
the
acting
as
the
user
as
a
as
a
user
agent,
to
help
you
to
perform
all
these
activities
to
perform
all
these
operations.
A
A
A
A
A
A
A
A
So
wale
is
like
the
it's
like
the
central
point:
it's
like
the
connecting
point
to
connect
all
those
application
with
different
kind
of
infrastructure,
and
also
it
is
connecting
with
users,
because
no
matter
what
kind
of
application
you
want
to
use,
you
will
always
required
to
have
a
software
to
help
you
to
manage
your
private
key
to
assign
the
transaction
to
broadcast
the
transaction.
You
know.
A
This
is
the
very,
very
simple
structure
for
for
looking
at
one
blocks
application,
but
actually
it
is
much
more
complicated
in
this
because,
because
for
for
one
application
normally
it
is
not
only
using
logic
or
knowledge
from
blockchain
from
smoke
ultra.
It
will
also
require
logic
and
under
informations
from
other
services
from
other
server,
not
only
from
blockchain.
So
let's
draw
a
more
comprehensive
one.
A
A
So
so
this
part,
this
part
a,
is
the
blockchain
infrastructure,
but
for
for
for
my
application
you
can
it
cannot
get
all
the
logic
or
all
the
knowledge.
Just
purely
from
blockchain,
your
structure
itself,
the
utility
is
very
limited
only
it
is
a
different.
It
is
a
distributed
larger.
It
can
only
record
the
the
information
like
what
you
have
those
kind
of
treatable
rights.
A
A
A
So
give
you
give
you
a
real
world
example
the
one
I
rewinds
very
familiar
with,
or
maybe
just
use
a
define,
as
example,
for
example.
Compa.
So
you
mind
you
imagine
this
is
the
smart
control
for
compa
for
sita,
which
you
can
impose
a
tie
into
the
smart,
contra
and
start
earning
interest
for
for
the
tyre
deposit
in
so
to
have
a
full
application
for
user
to
use
all
these
features.
A
A
Which
is
using
for
construct
the
transaction
for
smart
contract,
because
you
cannot
just
asking
smart
contract
by
I,
gave
him
a
call
say:
okay,
I
want
to
deposit
in
my
tie
into
in
twisty
tie
it
won't
work.
You
need
to
have
someone
currently
most
honest
earring,
that
is
some
JavaScript
code
need
to
have
those
code
to
help
you
construct
a
transaction,
and
then
this
code
construct
transaction
and
then
pass
these
the
transaction
to
your
wallet.
A
So
you
see
for
a
full
application.
Only
half
blockchain
is
not
enough.
It
will
also
require
logic
and
information
from
other
side,
and
this
makes
the
wali
itself
a
very
important
and
also
complex
piece
of
infrastructure,
because
it's
not
only
understand
those
days
more
contrast
and
those
block
trim
protocols.
It
also
need
to
understand
what
is
the
real
world
business
logic
like
the
logic
information
here.
A
Let's
see,
let's
have
a
move
to
the
last
topic.
Would
you
can
use
a
crypto
water
for
now
or
what
is
what
is
the?
What
is
the
crypto
wall
it
looks
like
for
now
and
what
will
will
be
looks
like
in
future,
so
I
list
on
some
question
here.
Maybe
maybe
you
never
have
such
start
question
before,
because
everyone
is
so
used
to
and
the
very
familiar
with
how
current
Internet
application
or
website
works
and
how
people
using
the
Internet.
A
But
these
are
some
critical
questions.
We
actually
should
ask
him
ourselves
yeah,
so
why
why
we
need
to
sign
up
or
why
do
I
need
to
sign
in
to
use
their
friend
in
tonight
services?
Why
and
why?
I
can't
just
use
Paypal
application
to
transfer
my
money
in
which
I'd
pay,
why
that
is
impossible
for
now
and
sometimes
I
use
YouTube
a
lot
and
also
I
use
Apple
services
as
well.
I
bought
a
lot
of
movie
from
iTunes,
then
why
I
can't
play
those
movies
in
YouTube.
A
A
A
A
That
is,
that
is
because,
when
we
design
the
Internet
at
very
beginning
there
is
no
ownership
mechanism,
so
there's
no
way
for
there's
a
there's.
Also,
there's
also
no
way
to
to
have
a
digital
representative
of
yourself
in
the
digital
world.
So
that's
why?
For
different
services,
we
use
username
and
password
to
verify
yourself
to
that
particular
services.
And
then
the
service
use
your
user
ID
as
identifiers
in
their
own
system.
Then
they
can
provide
services
to
you
and
also
because
all
different
services
they
are
not
integrated
with
each
other.
A
A
Basically,
basically
because
you
as
a
user,
cannot
provide
variable
information
like
who
you
are
what
you
have,
what
you
have
done
to
any
services,
and
currently
these
information
are
separate
in
different
services.
For
example,
PayPal
can
prove
PayPal
having
information
like
what
I
have
and
also,
if
I
tell
some
kyc
wisdom.
He
also
have
some
also
have
a
piece
of
information
about
what
I
have
and
also,
of
course,
all
the
all.
A
Also
in
Twitter,
so
so
this
is
the
this
is
what
happening
now.
So
all
these
kind
of
information
they
are
split
out
into
pieces
and
holding
by
different
services
and
an
under
the
is
a
big
platform,
there's
also
other
service
providers.
So
when
I
want
to
approve
to
service
provider
a
what
I
have
with
paper,
I
cannot
prove
directly.
I
have
to
go
through
PayPal.
A
A
A
A
A
They
are
all
crypto
toca,
it's
just
the
technology
you
are
using
to
tokenize.
The
information
is
different,
for
example,
as
I
mentioned.
If
you
want
to
tokenize
treatable
rights,
then
blockchain
is
the
best
technology
and
if
you
want
to
talk,
lies
you're
under
fire
and
like
your
your
reward
and
ohnkoji
those
things.
Those
realities
in
the
attestation
is
that
it's
the
right
technologies
so
basically.
A
Yeah,
so
this
is
what
I
just
quickly
dropped.
So
basically,
these
are
these
informations
like
what
you
have
what
you
have
and
who
you
are?
They
all
can
be
tokenized
into
crypto,
crypto
tokens
and
then
all
those
crypto
token
can
be
stored
locally
on
your
side
on
the
user
side,
then
you
can
use
these
very
flexible
information
on
whatever
services
you
prefer
and
and
this
this
will
be
what
will
happen
if
you
down
this.
B
A
So,
on
the
left
hand,
side
is
how
we
use
internet
now
and
on
the
right
hand,
side
is
how
we
use
in
tonight.
If
we
have
all
those
information
being
localized,
so
you
can
see
the
differences
previously.
If
you
want
to
use
this
in
the
radio
services
the
most
common
ways,
you
use
those
services
through
a
big
integration
platform.
If
you
are
living
in
China,
then
of
course
you
know,
there's
a
re
pay,
there's
a
witch
hat
and
they
are.
They
are
super
integration
platform.
B
A
This
gave
those
centralized
the
integration
platform,
a
very
good
position,
so
that's
why
they
are
growing,
bigger
and
bigger
and
bigger,
but
they
this
is
also,
on
the
same
time,
user
have
a
better
user
experience
because
they
can
do
multiple
things
through
one
platform,
but
on
the
same
time,
this
also
Chris
prep
problem.
One
problem
is
this:
type
of
integration
have
a
ceiling,
so
that
means
that
is,
you
cannot
to
eliminate
integration
and
also
the
services
you
can
choose.
It
is
deep
and
purely
depends
on
what
they
have
already
integrated.
A
By
date,
but
but
but
the
services
they
integrated
may
not
be
the
perfect
service
for
you,
and
this
also
creates
a
huge,
huge,
huge
problem
for
the
server
side,
because
the
service
sorry
most
of
the
service
side,
because
the
service
market
is
monopoly,
all
the
service
provider
they
they
are
not
competing
with
each
other
on
whether
they
provide
good
services
to
user.
They
are
actually
competing
each
other
with
whether
they
can
be
integrated
into
those
big
platform.
A
So
what
will
be
the
the
future
of
integration?
So
there
will
be
a
token
layer
for
in
tonight
for
all
the
services
and
all
those
as
I
mentioned
before.
All
those
token
is
controlled
is
hold
on
the
user
side.
So
this
make
each
user
can
have
their
own
integration
platform
and
the
services
they
can
integrate
is
unlimited.
A
So
this
is
what
we
call
the
integration
on
consumer
land
and
to
have
to
hold
all
these
tokenizing
information
to
interact
with
all
these
services
for
users.
On
the
user
side,
you
need
to
have
this
integration
platform,
or
you
say
you
need
to
have
this
piece
of
software
to
help
you
to
do
this,
and
this
is
the
future
for
crypto
warning.
A
And
this
is
this:
is
after
after
you
have
the
integrate
after.
This
is
a
would
what
the
future
looks
like
for
for
e-commerce
on
internet
previously.
If
people
want
to
want
to
want
to
treat
or
want
to
buy
by
star
sell
stuff,
they
always
need
to
go
through
a
centralized.
The
market
host
the
host
Pro
mainly
provide
the
two
functions.
A
My
function
is
to
to
match
the
the
buyer
and
the
seller
to
put
all
the
information
together
and,
more
importantly,
they
act
him
as
the
as
the
trust
is
the
party
to
host
a
transaction
which
is
the
guarantee.
If,
if
karo
give
money
to
James,
then
James
will
definitely
give
a
product
to
Karl,
and
this
can
also
be
replaced
by
a
blockchain
based
market.
A
There
will
be
much
less
friction
and
it's
there
will
be
a
free,
open
market
and
all
these
things
I
shared
here-
it's
not
like,
we
are
still
super
far
away
from
it.
It
is
happening
now,
so,
even
even
just
with
our
team,
we
have
done
many
of
these
experiments
on
tokenized
different
kind
of
informations
localize,
different
treatable
rice,
localize,
your
your
different
kind
of
and
panda
fires
and
use
it
for
different
populations.
A
A
Okay,
you
should
be
to
see
my
mobile,
and
this
is
alpha
volley,
which
we
want
to
build
into
this
integration
platform
for
on
the
user
side.
That
means
that
you
can
have
all
those
that
localize
the
information
in
one
place
and
you
can
use
it
on
different
services
and
I.
Just
show
you
one
application
we
did
with
it.
A
A
So
this
is
on
the
blockchain
side.
This
is
there's
a
small
contra
on
a
Syrian
Network
and
inside
a
small
contract.
It
registry
80
the
ownership
of
each
car
coat
each
car
token,
and
also
they
find
the
transaction
rules
of
how
this
ownership
can
be
transferred.
And
if
you
open
up
the
token,
you
can
see
there's
a
whole
bunch
of
different
services
integrated
into
this
car
ownership
token.
So
basically,
this
becomes
a
car
portal
for
user.
A
In
this
stock
panel,
you
can
prove
your
ownership
to
the
physical
car,
and
then
the
car
will
grant
you
access
and
then
you
can
do
operations
like
opened
or
closed
the
door.
Locate
where's
the
car
start
engine
stops
engine
audience
and
in
this
advanced
asian
panel
you
can
prove
your
ownership
to
third-party
service
provider.
Like
a
New,
South,
Wales,
Transport
Department,
then
you
can
claim
a
registration
for
your
car.
A
It's
like
I'll
show
you
here
is
a
partition
issued
by
the
New
South
Wales
transponder,
the
road
and
marine
services
department,
and
also
with
this
registration
and
your
ownership
token.
You
can
prove
to
insurance,
you're,
really
a
car,
and
you
are
legal
to
drive
the
car.
Then
you
can
easily
buy
insurance
from
an
insurance
provider
with
those
sign
up
without
signing
without
copy-paste
result.
The
scan
your
registration
under
submitted
without
scanning
or
your
travel
item
is
all
