Description
No description was provided for this meeting.
If this is YOUR meeting, an easy way to fix this is to add a description to your video, wherever mtngs.io found it (probably YouTube).
A
A
A
B
A
So,
are
you.
A
Give
it
one
minute:
if
if
james
brown
doesn't
come,
then
we
start
anyway.
A
A
A
C
B
Are
you
tall
hello?
Are
you
able
to
hear
me
now?
Yes,
we
are
all
right
great.
I
don't
know
it's
sad.
It
apparently
changed
the
setting
to
use
a
microphone
that
didn't
exist,
existed.
A
So
today
I
only
only
want
to
cover
two
agendas
and
two
topics.
Sorry,
I
didn't
write
the
agenda
before
the
meeting,
because
later
I
had
a
meeting
after
this
and
couldn't
go
too
deep
into
either
direction,
and
so
the
two
things
I
want
to
talk
about
is
first
the
use
cases
that
can
be
that
that
can
be
supported
by
a
check
protocol
and,
second
being
that
the
javascript
interface
for
for
for
working
with
cards
and
token
script
on
the
web,
and
I
will
go
go.
A
A
A
Hi
james
brown,
nice
to
see
you
hi
hi,
so
james
and
boone,
remember
that
we
talked
once
about
activating
cards
from
javascript.
Now
that
was
a
quite
a
few
weeks
ago
and-
and
we
haven't
been
able
to
do
that
anything
on
that
front
until
very
recently
and
is.
D
This
for
the
the
small
items
on
the
the
item
view.
A
So
here
is
a
bit
of
sample
code
that
I
said
I
wrote
like
a
sample
api
interface
and
I
have
an
alternative
which
I
didn't
write.
But
let's
look
at
this
first,
so
this
page
takes
an
example
of
entry
token.xml,
the
the
you
know,
the
default
simplest
telescript
we
ever
signed,
and
then
there
are
two
things
happening:
first,
that
this
page
is
demonstration
of
showing
the
card
in
the
web
page
and
then
there's
iframe
as
a
container
for
the
token
card,
and
when
the
document
is
loaded.
A
D
A
And
then
one
thing
to
be
aware
is
in
this
case
the
test
page
seems
to
be
from
the
same.
The
test
page
since
it
simply
like
can
be
the
depth
the
entry
token,
but
architecturally.
This
doesn't
have
to
be
the
case.
So
an
ideal
example
not
this
one.
A
I
do
example,
would
be
the
web
page
in
the
e-commerce
website
and
the
action
might
be
provided
by
the
payment
token
or
even
aae,
so
the
website
is
from
different
company
or
entity
than
the
token,
and
this
is
using
a
token
script
bootstrap.js
this
these
tokens,
this
javascript
simply
does
nothing
at
all
if
it
detected
a
that
browser
with
hookah
script
support,
but
if
it,
if
there
is
a
focus,
if
the
browser
doesn't
support
token
script,
which
is
100.
D
A
Then
this
javascript
in
this
library
provided
any
the
underlying
code
for
this
kind
of.
A
You
mean
what
what
are
the
token
attributes
right?
Yes,
where
where
do
they
get
pulled
from
so
let's
say:
if
we
don't
use
context,
then
we
assume
the
context
being
that
user
is
the
owner
of
the
token
right.
A
Okay,
yeah,
in
that
case,
the
token
script
has
all
the
description
of
how
to
get
every
attribute
and
the
token
script
bootstrapped.js
and
is
able
to
get
all
the
attributes
and
in
the
traditional
way.
Without
the
token
token
layer,
without
data
layer.
Because
there's.
D
Just
just
as
a
sort
of
an
aside,
we
have
the
way
that
we
currently
do
this
in
the
dmz
is
we
have
a
sort
of
back
end
that
resolves
attributes
via
the
the
same
engine
that
our
android
users?
So
that's
how
we
do
it
currently.
C
D
No,
I
think,
I
think
the
idea
is
to
make
it
into
a
jar
and
to
make
a
javascript
engine
to
do
this.
A
That
doesn't
exist
so
far.
So
if
your,
if
your
browser
supports
a
token
script,
it
has
a
token
script
engine
in
it,
then
it
should
know
for
the
given
context
how
to
populate
the
data,
and
it
might
already
have
the
data.
A
If
you
are
talking
about,
if
the,
if
the
the
browser
does
not
support
a
toggle
script
engine,
then
bootstrap.js
provides
this,
of
course,
without
the
the
ptips
guarantee,
but
it
does
provide
the
functionality.
A
Goes
into
the
context,
oh
yes,
I
think
so
in
this
context,
if
the
default
context
is
always
owner,
so
context
has
a
few
things
like,
for
example,
whether
or
not
this
token's
behavior
is
related
to
certain
website,
whether
or
not
it's
related
to
a
certain
user
like
if
you,
if
you're
owner
of
the
token
or,
if
you're,
just
looking
at
tokens,
someone
owns
or
that,
if
you
are
the
borrower
of
token
or
the
the
lender
of
the
token,
or
that,
if
the
token
is
programmed
to
only
work
with
certain
context,
for
example
a
wallet
or
a
certain
geographical
location
section.
C
A
Yes
yeah,
so
in
this
case
we
have
a
minimal
example
because
enter
action.
Only
does
one
thing
that
has
let
you
enter
the
door.
There's
no
payload.
Is
this?
What
you
mean
because
enter
simply
creates
a
a
test
station
that
can
be
used.
A
C
Yeah
yeah,
because
you
you
mentioned
this
token
script
bootstrap.js.
It
basically
implements
the
token
script
engine
and
I'm
trying
to
understand
when
we
don't
have
the
token
script
engine.
How
does
this
puts
token
script?
Bootstrap.Js
provide
access
to
attributes
to
the
user's
wallet
and
post
the
transaction.
C
A
Well,
first,
the
javascript
detects
if
there
is
web3.js
installed
and
if
it
is
has
step
by
step.
If
web3.js
is
installed,
then
it's
all
right.
If
it
does,
if
there
is
no
web3.js,
maybe
a
version
of
web3.js
is
in
embedded
in
the
bootstrap
as
a
default
for
back,
then
it
will
check
if
the
user
have
an
account
and
if
the
account
requires
connection,
it
would
ask
the
users
to
make
a
mask,
for
example,
to
start
the
connection
to
the
account.
A
A
C
Right
so
when
you
say
boots
token
script
bootstrap,
so
that
it
still
requires
something
like
metamask.
B
A
B
A
A
Does
it
make
sense
so
far,
then
I
will
start
asking
a
few
questions
for
her,
how
you
would
design
it?
Yes,
yes,
okay,
okay,
first
and
I
know
that
the
handling
of
the
promise
promise
is
empty
from
line
20
to
2021.
There
should
be
stuff
that
will
be
the
separate
stock
script
meeting,
the
first,
a
point
being
that
you
know
that
when
we
pass
context-
and
we
will
pass
a
payload
here-
we
are
passing
a
lot
of
stuff.
A
So
depends
on
what
what
the
the
thing
is
doing
at
the
moment.
So
imagine
there's
a
payment
token
right,
then
the
payload
will
necessarily
include
which
address
to
pay
and
how
much
to
pay
and
the
other
in
another
action.
Maybe
let's
say
if
you
have
a
line
of
credit
enabled
by
aae,
then
if
the
action
is
also
called
pay,
it's
like
a
re
draw
from
the
line
of
credit
and
pay.
A
Then
you
will
have
three
in
the
payload
one
is
the
target
address
and
the
other
is
the
the
amount
and
the
third
is
the
type
of
currency,
so
similarly
context
might
have
other
stuff
in
it.
So
I'm
thinking
that
a
alternative
approach.
A
A
Oh,
by
the
way,
if
you
are
a
e-commerce
website
that
wish
to
incorporate
a
crypto
payment
token,
then
the
function
here
is
the
only
thing
you
will
need
to
program.
A
A
A
A
I
don't
know
what
happened.
I
couldn't
share
anything
after
so
many
years.
I
still
don't
know
how
to
zoom.
A
A
A
The
reason
might
it
might
be
better
is
we
can
potentially.
D
A
A
A
Basically,
everything
else
is
covered
by
a
dense
fog
and
you
only
have
the
foreground
where
there's
action
that
you
you
are
dealing
with
dealing
with.
But
if
you
have
water
connected
it
might
pop
up
in
your
mobile
phone
right.
D
Yes,
that's
that's
pretty
much
it
yeah.
So
basically,
what
you're
saying
is:
if
you've
got
a
a
browser,
a
browser
plug-in
wallet
like
metamask,
then
it's
gonna
be
handled.
All
natively,
like
you
say,
like
the
new
york
times,
cable
message,
but
otherwise
it
put
something
pops
up
in
a
wallet
and
that
there
wouldn't
wouldn't
there
have
to
be
like
a
signal
on
the
the
website
to
say
that
is
awaiting
wallet,
action.
A
Yeah
and
so
so,
let's
say:
if
you
are
using
a
token
script,
enabled
metamask,
then
you
don't
need
that,
because
metamask
will
be
showing
the
action
in
the
metamask
drawable.
Yes,.
D
Yes,
but
it
is,
isn't
the
intention
of
this
to
be
universally
compatible,
so
basically
it's
a
it's
a
layer
on
top
of
web3
dot
js.
So,
basically
you
can
metamask
and
drive
token
script
without
knowing
what
came
to
you,
yeah.
A
A
Is
abstracted
out?
The
intention
is
that
a
web
developer
who
wants
to
be
compatible
with
the
tokens,
do
not
need
to
use
web3
dot
js,
and
they
don't
need
to
know.
They
only
need
to
launch
the
right
token
and
the
trust
relationship
which
smart
contract
to
call
and
all
kinds
of
things
are
sorted
out
for
them.
They
work
a
layer
higher.
D
Yes,
yes,
that's.
I
understand.
A
Okay,
so
so
the
reason
I
pro
and
thinking
about
this
design
is
that
we
can
potentially
do
something
like
this.
A
B
D
A
A
A
A
Okay,
then
intellij
cannot
tell
you
that
a
amount
is
expected.
C
A
C
A
Yeah,
okay,
yeah
and
also
this
is
the
we.
I
don't
know
if
you
remember,
but
I
always
mentioned
that
the
token
script
should
be
deployable
on
the
web.
So
in
this
case,
if
the
entry
token.xml
is
provided,
it
can
only
contain
the
portion
of
token
script
that
is
needed
for
this
web
action
to
be
executed.
A
So
let's
say,
if
you
have
token
script
entry
token,
that
the
full
token
script
include
actions
like
authorizing
someone
else
to
access
the
door,
then
that
action
is
not
needed
to
be
included
in
the
token
script
linked
for
this
webpage.
A
A
Unless
we
make
it
able
to
do
that,
so
if
we
make
a
plug-in
for
metamask,
we
probably
will
be
making
a
plugin
that
implements
actions,
but
it
doesn't
provide
any
more
context
than
than
what
mathematics
already
have.
So
that
means,
if
you
use
metamask-
and
you
are
using
a
deployed
web
deployed
token
script,
then
web
metamask
doesn't
have
a
locally
installed
token
script.
A
Repository
so
shouldn't
that
all
be
handled
by
token
script,
bootstrap
all
handled
by
the
token
script
plugin
in
metamask
in
this
case,
because
metamask
has
a
token
script.
Plugin
we're
talking
about
scenario
where
bootstrap
is
not
needed.
That
means,
if
you
are
using
alpha
wallet,
of
course,
you
have
the
full
token
script
installed
in
the
wallet,
but
having
the
full
script
installed
in
the
wallet
is
not
a
requirement
of
using
token
script
or
deploying
token
script.
A
You
only
need
to
have
the
full
token
script
employed
installed
in
your
wallet.
If
you
provide
the
wallet
context,
we
briefly
talked
about
this
before
remember
that
that
when
we
were
trying
almost
going
to
offend
apple
by
making
downloadable
components,
I
explained
that
it's
deployed
on
the
web.
The
fact
that
it
can
be
downloaded
can
be
considered
as
a
special
case
where
it
is
deployed
on
the
web,
because
it's
just
that
one
additional
context,
instead
of
instead
of
that,
this
thing's
designed
for
being.
A
A
A
A
Sure,
okay,
so
so
so
next
one
is
about
I'm
going
to
share
a
different.
A
A
So,
do
you
guys
remember
the
czech
protocol
we
discussed
heavily
in
2018
but
didn't
discuss
in
2009.
I
believe
so.
A
check
protocol
is
is
basically
it's
a
multisync
protocol.
What
it
does
is
it
allows
one
person
to
write
a
check
that
allows
the
other
person
to
redeem
token.
It
doesn't
have
to
be
redeemed.
A
Token,
can
be
progressing
like
like
being
able
to
vote
or
anything
that
smart
contract
would
ask
you
to
do,
but
the
process
of
writing
a
check
and
the
rea
and
cashing
out
the
check
doesn't
have
to
cash.
You
actually
cash
out
actually
money,
it
can
be.
Action
can
be
done
on
the
smart
contract
and
before
the
check
is
used,
it
doesn't
have
to
be
available.
A
It
is
not
available
on
the
on
the
blockchain
at
all.
So
so
so
so
is
this.
I
think
we
haven't
talked
about
check
for
a
long
time.
Does
it
ring
a
bell.
A
Yes,
okay
and
then,
and
the
first
minimum
viable
product
using
check,
is
the
one
that
where
we
send
ether
by
by
email
address.
So
what
you
do
is
you
can
write
a
check
and
allow
another
person
to
redeem
your
ether,
certain
amount
of
ether
if
the
other
person
is
able
to
provide
a
attestation
that
satisfies
the
criteria
in
the
check
and
the
nature
of
it.
To
be.
Multi-Sig
means
that
the
writer
of
the
check
put
a
signature
there
and
the
person
who
redeem
it
needs
to
put
a
final
signature
on
the
transaction.
A
B
A
Access
that
is
only
employees
are
tested
like
a
tested.
Bookkeeper,
maybe
is
able
to
use
it
to
pay
for
goods
and
services,
and
if
the
right
employee,
under
the
permission
and
has
a
check
and
has
a
test
station,
he
is
able
to
pay,
let's
say
for
hosting
on
the
web
and
which
is
payable
by
ether.
He
can
just
combine
his
check
and
the
test
station
and
do
this
payment,
and
this
flow
is
actually
the
same
as
as
as
it
would
happen,
with
alice,
sending
one
ether
to
bob
on
the
right
side.
A
Contract
work
is
the
case.
This
is
the
case.
Actually
we
discussed
in
the
bank
as
well,
and
so
a
customer
wrote
write
a
check
of
5
ether,
let's
say
house
renovation,
and
if
the
job
is
done,
the
worker
is
able
to
redeem
the
money
and
the
contractor
hanging
down
the
job
would
get
a
third
party,
let's
say
a
validator,
to
validate
the
job
being
complete,
that's
the
test
station
and
then
he
can
take
this
test
station
and
redeem
the
money.
That
would
be
the
two
users
use
cases
of
check
protocol.
A
The
other
two
sunil
didn't
select.
First,
reverse
bidding
reverse
speeding,
attender
tender
is
the
right
name.
A
A
A
A
signed
message
proving
a
certain
customer
has
the
capability
of
investing
in
certain
high-risk
class
assets,
for
example,
junk
bonds,
and
then
the
the
the
the
broker
would
take
customers
money
if
the
customer
comes
with
such
a
test
station
now,
if
we
convert
that
into
a
ethereum
example
that
would
be
in
order
to
participate,
ico
pre-sales,
you
need
to
carry
money
as
well
as
attestation
for
proving
that
you
are
sophisticated
investor
yeah.
A
That
would
be
also
be
a
use
case
of
the
czech
protocol
and
because
the
checkpoint
check
particle
was
refined
by
thor
through.
A
Quite
a
lot,
I'm
thinking
about
generalize
it
a
little
bit
and
then
provide
a
paper
on
the
use
of
attestation
of
check
and
that
that
is
the
line
of
work
that
can
go
on
as
we
enter.
The
second
phase
of.
A
Second,
phase
of
a
send
ether
by
identifier
test
station
mvp
and
there
are
only
two
minutes
left.
So
if
you
have
any
questions,
please
you
can
you
can
shoot
more
questions.
Just
like
anyone
who
wants
to
live
by
on
time
can
leave.
They
can
always
stay
a
little
bit.
C
A
D
I,
like
the
the
authorization
access,
how
what
would
that
actually
look
like
in
terms
of
the
infrastructure.
A
Just
like
replace
ceo
with
alice
and
replace
the
employee
with
bob,
and
we
have.
D
I'm
thinking
you
could
do
if
you
abstracted
this
slightly,
you
could
do
something
similar
that
we
talked
about
with
the
the
car
next
door.
You
know
how
you
can
authorize
somebody
to
use
so
say
if
you've
hired
the
car
next
door,
and
you
can
authorize
your
friend
to
use
it
for
an
hour
of
your
time.
Yeah.
D
D
Submit
that
to
some
kind
of
service,
maybe
yeah
some
kind
of
infrastructure
service
that
the
car
next
door
decentralized
car
next
door
is,
is
operating
or
maybe
even
go
one
step
beyond
that
and
actually
the
actual
the
device
that's
operating
inside
the
car
itself
can
validate
the
attestation.
D
A
D
Yes,
yes,
yeah
yeah.
I
really
like
this.
So
how
would
that
actually
appear
in
the
wallet?
So
let's
say
I
give
the
I
send
the
attestation
to
my
friend
and
then
he
will.
D
He
will.
Presumably
it's
like
an
xml
or
something
like
that.
Some
kind
of
payload
email,
payload
or
chat
payload
he'll.
He
will
then
click
on
that
and
the
wallet
will
open
it
and
then
it
will
appear
as
an
attestation
inside
his
wallet
that
he
can
then
interact
with.
D
D
So
let's
go
go
to
the
car
next
door,
one
let's
say
I
want
to
authorize
my
friend
to
use.
I
I've
hired
a
car
next
door,
so
I've
got
it
for
a
day.
I
want
to
authorize
my
friend
to
do
it
for
use
it
for
one
hour.
So
presumably
I
would
generate
an
attestation
based
off
of
my
authorization
to
use
the
car
for
one.
For
one
day
I
would
generate
an
artist.
A
If
you
have,
if
you
can
have
a
let's
say,
if
you're
you,
if
you're,
if
you
start
the
protocol
like
you,
are
the
borrower,
yes,
then
you
can
just
send
your
public
key.
D
Yes,
I
was
actually
talking
about
say
if
I
I'm
authorizing
a
third
party
to
use
my
temporary
authorization.
So
let's
say
so:
I'm
I'm
I've
just
rented
from
car
next
door,
a
car
for
one
day,
but
I
want
a
friend
wants
to
use
it
for
one
hour.
So
I
presumably
there
would
be
some
kind
of
flow
that
I
can
generate
at
a
station,
send
it
to
him
and
he
would
then
be
able
to
interact
with
that
at
a
station
via
his
wallet
to
operate
the
car.
A
Authorized
car
next
door
and
car
next
to
authorize
you
and
the
smart
contract
may
limit
the
level
to
true.
D
I
mean
obviously
there's
a
there's
limitations
of
like
insurance
and
stuff
like
that
and
so
you'd
need
and
that's.
But
if
you
had
a
standard
insurance
attestation,
then
the
attestation
that
you
give
to
your
friend
that's
generate.
That's
like
a
sort
of
a
template
from
comic
store
would
only
work
if
your
friend
also
submits
an
insurance
valid.
You
know
like
a
license
and
insurance
validation,
attestations.
A
Yes
and
in
this
case,
there's
a
clear
text
attestation
and
there
is
an
unclear
one,
so
what
you
do
is
you
show
the
clear
tax
detection
which
shows
which
insurance
company
shared
whom
next
to
the
website
and
then
when
you
connect
it
to
smart
contract,
only
the
relevant
information
is
is
is
used
and
other
parts
are
obscured
and
and
also
that
identity
related
information
has
to
be
hidden.
A
It's
getting
more
complicated
that
way,
but
the
idea
is
you
you,
you
are
able
to
pass
some
data
so
so
pass
some
data
between
the
party
and
all
of
them
can
talk
to
the
blockchain.
At
the
same
time,
your
model
looked
like
that.
A
A
A
A
C
Yes,
so
is
the
token
script
bootstrap.js
replacement
for
when
the
token
script
engine
is
not
available.
A
And
yes,
in
this
case
there
are
a
lot
of
problems,
but
we
we
simply
chose
to
say
like
in
this
case.
People
have
to
accept
the
problems.
A
C
A
Oh,
that
has
nothing
to
do
with
bootstrap
you.
When
you
deploy
a
token
script
on
the
web,
you
only
need
to
deploy
the
the
functionalities
that
is
necessary
for
you
to
support
the
tokenization
use.
So,
for
example,
if
you
are,
if
you
are
selling
selling
bicycles,
your
website
is
boone's
bicycle
shop,
okay,
bb!
Then
you
only
need
to
include
the
payment
token
checkout
action.
C
A
And
that's
that's
reasonable
too,
because
that's
the
the
how
everything
on
the
web
is
designed
and
that's
also
one
of
the
reasons
we
start
with
xml
signature
as
well,
because
you
can
sign
multiple
portions
of
the
website
like
every
action
sign.
You
can
sign
it.
So
what
you
can
do
is
to
have
a
you
don't
need
to
like
canonicalize
it.
I
don't.
I
don't
know
if
I
mentioned
it
before,
but
the
signature
has
nothing
to
do
with
clinicalization.
A
Sorry,
it
has
actually
standard.
Xml
signature
is
on
the
kinetic
canonicalized
node,
but
it
doesn't
require
the
xml.
A
So
you
can,
you
can
have
a
this
xml
file
refer
to
pictures
at
other
places
and
and
then
they
would
still
work
as
long
as
the.
In
the
end,
the
signature
matches
that
you
want
to
canonicalize,
because
that's
happened
to
be
a
packaging
method
to
deliver
to
the
wallet.
A
And
if
you
don't
trim
it,
it
just
doesn't
work,
because
when,
when
bootstrap.js
or
even
the
tokenscript
engine
see
that
there's
an
entry
token.xml,
it
has
only
two
choices:
either
get
the
file
or
don't
get
the
file.
You
cannot
say:
okay,
let
me
get
the
file,
but
only
the
portion
about
action.
C
A
Yeah,
so
in
this
case,
the
best
practice
is
to
include
the
tokenscript
entry
token.xml
file
without
the
two
other
actions,
because
it's
not
possible
for
token
script,
engine
or
bootstrap.js
to
only
download
the
portion
inside
the
entry
token.xml.
That
is
related
to
the
action,
because
there's
no
way
to
download
only
a
portion
of
the
file.
A
Should
not
be
downloaded,
so
let's
say
you
have
a
entry
token.xml
file
and
has
eight
megabytes.
Let's
say
that
every
megabyte
there
are
eight
languages
in
it,
so
you
can.
B
A
Seven
of
them,
if
your
html
page
is
english
right,
so
that
reduces
your
eight
megabytes
into
one
megabyte
and
then
let's
say
you
have
entry
token,
which
has
three
actions.
One
is
called
enter
and
the
other
is
called
authorize
and
the
third
is
called
revoke
authorize.
Then
the
authorizing
remote
authorized
only.
C
A
No
okay,
you
can
also
provide
views
in
separate
xml
files
and
the
xml
file.
Signature
would
also
stand.
That
is
also
an
alternative
way
of
deploying
it,
but
some
feels
more
complicated
to
me,
so
it's
possible
to
deploy
segments
of
xml
file
and
then
use
the
signature
scheme
to
cover
you
know.
Xml
signature
can
cover
signature
content
not
only
in
the
current
xml,
so
you
can.
A
File
called
signature.xml
that
would
be
interesting
way
to
deploy
too.
I
feel
that
might
be
more
complicated
or
challenging
for
the
for
the
web
web
guy,
but
with
the
right
tool.
That
would
be
possible
too.
So
in
that
case
you
will
have
entry,
token.v1,
actually
token.view2.xml
and
angiotoken.vo3.xml
entry
token.data.xml
and
the
signature.xml.
C
C
A
The
fact
that
the
token
script
can
be
developed
and
deployed
on
the
web
without
the
requirement
of
the
wallet
meaning
without
required
user
agent
being
able
to
download
and
maintain
version
of
every
token
script
file
is
intended
feature
it
has
been
in
the
beginning.
But
we
have
decided
to
focus
on
the
wallet
because
in
two
years
ago,
in
the
meeting
we
decided
to
focus
on
the
wallet
simply
because
of
that.
But.
A
Yeah,
I
I
hope
that
addressed
the
the
concern.
If
you
do
have
any
like
design
a
device
on
this
or.
C
C
A
That's
something
so
one
example
is
token
negotiation.
So
let's
say
this
talk.
This
website
is
able
to
work
with
10
different
tokens.
If
you
load
bootstrap.js
token
script,
token,
negotiation
will
be
done
automatically.
There's
no
need
to
write
a
single
line
of
javascript
and
only
the
negotiating
token
will
function.
A
Shall
I
take
you
back
to
the
token
negotiation
case?
Sure,
okay,
so
so
token,
negotiation
is
also
we
never
prioritize
it,
but
but
it's
also
one
of
our
creations
back
in
our
experimentation
with
business
cases.
Let's
see
if
maybe
it's
in
dock,
no,
no,
it's!
A
Wiki,
so
in
the
case
of
token
negotiation,
the
process
doesn't
start
from
javascript.
It
starts
from
the
negotiation
can
happen
with
you
can
do
javascript
based
negotiation.
I
can
do
automatic
one,
but
the
idea
is
once
you
have
a
token
token
start
to
function,
not
that
you
know
in
you
you,
you
already
know
what
token
you
are
going
to
use.
So
in
this
case
you
already
know
what
token
you
are
going
to
use.
Okay,
because
this
is
just
a
website
for
this
purpose.
A
But
if
your
e-commerce
website,
you
might
be
compatible
with
five
different
tokens,
and
you
want
to
negotiate
a
little
bit
instead
of
using
javascript
to
check
to
create
a
token
object
for
everyone
and
download
the
xml
unnecessarily,
even
though
the
token
doesn't
really
exist.
A
A
C
A
So
the
negotiation
ideally
would
happen
here
by
declaring
that
this
webpage
is
able
to
work
with
tokens
like
satisfying
satisfying
this.
This
query,
and
we
need
to
in
turn,
provide
a
javascript
way
that
a
bunch
of
javascript
would
be
activated
on
negotiation
and
by
the
time
javascript
is
activated
on
negotiation.
It's
the
the
token
of
the
token
script.
Object
is
already
created
for
the
voyage
and
pass
it
to
it.
A
A
Yeah,
okay,.
A
Yeah,
thank
you
very
much
and
if
you
have
more
questions,
just
shoot
message
on
me
on
telegram
and
then
we
can
go
on
from
there.
Okay,
it's
one
hour
long!
Thank
you
very
much
for
everybody.
A
B
A
And
then
we'll
go
go
through
that
route
a
little
bit
later.
The
only
introduction
article-
and
it
is
a
two
hour
from
now
to
my
three
more
than
three
hours
now
to
my
presentation.
So
I
should
be
able
to
provide
a
five
minute
article
yeah.
B
Yeah
also,
I
just
wanted
to
to
to
mention,
as
I
I
sent
you
an
email
from
my
previous
discussion
about.
Well.
Actually,
it
was
supposed
in
the
community
that
about
about
attestation
and
the
use
case
as
well.
We
were
questioning
why
it
hasn't
really
caught
on
previously
when
other
people
have
looked
at
it.
So
it's
just
to
to
keep
people
aware
like,
even
though
that
the
identifier
of
a
person
that
is
cashing
a
check
or
using
the
association
is
anonymized.
B
B
B
A
Meanwhile,
it
gives
us
a
line
of
credit
so
that
we
can
pay
certain
goods
and
services
with
all
the
currencies
that
the
website
asks
for
and
in
that
use
case,
the
test
station
employee
attestation
is
definitely
used
together
with
authorization
of
the
withdrawal
operation,
and
this
would
this
would
already
be
a
real
use
case
that
business
can
use,
although
it
would
necessarily
expose
the
pattern.
But,
however,
the
pattern
is
exposed
anyway.
If
they
want
to
use
ether
to
pay
anything
so
yeah.
A
A
There
is
a
good
chance
that
the
reason
is
related
to
privacy,
but
there's
also
might
be
a
chance
like
like,
for
example,
businesses
are
simply
took
too
much
concern
with
regulation
and
they
simply
want
to
cash
out
all
the
crypto
investment
in
the
us
dollar
so
that
they
can
do
it
in
the
bank.
Maybe
that
could
be
the
case
so
yeah
having
a
working
working
prototype
like
and
working
more
mvp
like
sending
ether
to
someone
by
event.
Identifier
gives
us
the
the
was
access
to
the
landscape.
A
B
B
Are
you
know
you
can
derive
new
random
keys
from
from
your
current
key,
so
I
guess
that
would
be
a
way
of
combining
hp
based
credential
and
attestation,
with
newly
derived
keys
also
to
hide
the
address,
but
I
mean
in
any
case,
if
it's
money-based,
you
need
to
get
your
money
out
of
whatever
address
it
comes
to
at
some
point
right,
but
in
particular
in
the
case
where
it's
meant
for
like
borrowing,
a
car
or
or
access,
basically
like
authorizat
authorizing
authorizing
things,
it
might
make
sense
to
to
to
do
an
add-on
based
on
attribute-based
credentials
in
order
to
hide
usage
pattern,
especially
when
there's
nothing
of
the
the
nothing
financial
involved
that
can
be
used
to
trace
yeah.
B
A
Yeah
yeah,
that's
certainly
interesting,
certainly
something
that
knowing
that
is
available.
If
we
have
this
problem
is
really
good,
should
we
explore
it
right
now,
probably
not
but
very,
very
useful
in
the
long
run.
A
Also,
if
you
have
a
third
party,
a
tester
who
is
able
to
test
like
which
contract
job
is
done,
you
can
simply
observe
what
he
had
tested
on
and
learned
a
lot
of
things
yeah
that
that
that
is
the
issue
yeah
or
also
in
trade
finance
would
be
an
issue
I
think
yeah,
let's
see
which
business
can
we
marry?
First.
B
I
mean
I
would,
I
would
guess,
a
lot
of
situations
because,
basically,
in
those
situations
you
get
some
some
secret,
you
attest
to
some
secret
value,
which
is
then
used
to
derive
a
proof.
Basically.
So
this
means
that
even
the
attester
cannot
see
if
and
assist.
If
this
attestation
has
been
used
to
derive
a
certain.
