Welcome
to
p
penny
episode,
87
I'm
your
host
Puja
ranjan,
and
in
this
episode
we
will
be
learning
about
an
upcoming
standard
for
nft
EIP
5606
Multiverse
nfts
about
the
proposal.
Eip5606
is
a
standard
track.
Erc
created
on
September
6th
is
currently
in
the
draft
status
to
provide
an
overview
of
The
Proposal.
We
are
joined
by
our
guests
on
the
show
and
co-author
of
EIP
5606
gaurang
darvekar.
A
B
A
A
Right
I
I
understand
this
EIP
reads
very
interesting,
especially
to
me
and
I'm,
looking
forward
to
hear
what
you
have
got
to
share
with
us,
but
before
we
get
into
the
woods
of
The
Proposal
may
we
have
a
quick
introduction
of
you
and
your
journey
with
the
ethereum
ecosystem.
I
understand
you
have
a
slide,
so
maybe
you
can
start
sharing
and
yeah.
We
can
take
it
from
there.
B
You
know
and
from
there
we
grew
that
Meetup
grew
up
to
like
thousands
of
people
you
know
and
now
I'm
based
in
London
and
I'm.
Also
one
of
the
co-organizers
of
ethereum,
London
Meetup,
so
I've
always
been
involved
in
the
community
and
I
I
love
ethereum.
You
know,
I
love
the
thoughts
of
ethereum,
the
decentralization.
B
A
B
Sure,
thank
you
so
much
so
before
we
go
into
the
EIP.
Let
me
talk
about
few
of
the
problems
that
we
are
trying
to
solve.
This
is
kind
of
the
motivation
behind
the
CIP.
You
know
so,
as
you
all
know,
currently
there
are
just
too
many
metaverses
too
many
nft
projects
and
too
many
play
to
earn
blockchain
games
right.
B
If
you
go
on
openc,
if
you
go
on,
looks
rare
or
any
of
these
marketplaces,
you
will
see
thousands
of
NXT
projects
out
there
right,
but
the
problem
is,
none
of
them
are
connected
to
each
other.
None
of
them
talk
to
each
other
right,
and
so
let's
say
you
want
to
buy
some
asset
like
a
digital
asset.
You
need
to
publish
it
Mentor
it
on
multiple
places,
on
multiple
marketplaces
and
then
buy
it
in
from
multiple
places.
Just
like
too.
D
B
Right
now,
right,
there
are
just
too
many
marketplaces
too
many
inactive
projects
out
there,
and
also
there
are
no
standards
for
this
interoperability.
Some
people
have
been
trying
to
come
up
with
standards,
but
those
standards
haven't
been
accepted
right.
No
one
is
really
using
those
standards
each
of
the
games,
each
of
the
metaverses
is
trying
to
do
their
own
thing
and
that's
why
the
user
base
is
completely
fragmented
today.
So
you
know
you
have
a
few
hundred
users
on
200.
B
You
know
daily
active
users
on
decentral
and
you
have
a
few
users
on
Sandbox
on
crypto
voxels,
but
you
know
there's
nothing,
there's
no
one
thing
which
just
joins
all
of
them
together
and
we
believe
that
this
VIP,
which
is
eip5606,
could
be
the
first
step
towards
going
there.
You
know
towards
that
goal
just
to
help.
You
understand
the
problem
a
little
better.
Let
me
take
an
example
of
a
digital
asset
like
a
golden
jacket
right.
So
now,
let's
consider
an
example.
B
You
have
a
fashion
brand
who
has
designed
this
amazing
looking
golden
jacket
and
now
they
want
to
create
the
digital
version
of
this
jacket,
as
a
variable
on
multiple
metaverses.
Now.
Consider
now
remember
in
this
case
I'm
only
selecting
or
I'm
only
talking
about
the
top
four
metaverses,
which
are
sandbox
in
the
in
the
crypto
space
right
now:
sandbox,
decentralized,
voxel,
sensor,
ambient
space
I'm,
not
even
talking
about
other
ones
like
other
side
or
any
of
the
other
metaverses
coming
up
right.
B
If
you
just
consider
these
top
four
metaverses
this
golden
jacket
to
create
this
golden
jacket
as
a
variable,
you
need
to
create
eight
nfts
in
total,
and
that's
because
you
need
to
create
one
nft
on
Sandbox
one
energy
on
decentral,
end
and
believe
it
or
not,
five
nfts
on
work
cells,
and
that's
because
on
voxels
you
have
to
do
a
torso
nft.
You
have
to
do
two
nfts
for
your
upper
arms
and
two
for
your
lower
arms,
so
five
nfts
and
voxels
and
another
anything
on
somnium
space
now
see.
B
The
problem
here
is
all
these
eight
nfts.
In
reality,
they
just
represent
one
thing,
which
is
a
golden
jacket
right:
a
golden
jacket
by
let's
say
brand
brand
a,
but
you
have
eight
nfts
on
the
blockchain
right
now.
If
you
look
at
the
blockchain
as
a
whole,
each
of
these
eight
nfts
could
have
100
copies
or
thousand
copies
right.
So
let's
say
they
have
a
thousand
copies
each.
B
There
will
be
8
000,
different
nft
token
IDs,
which
are
not
connected
to
each
other,
but
in
reality
they
are
just
the
same
thing
right
and
now,
if
you
start
looking
at
games
in
the
meta
versus
or
if
you
start
just
looking
at
games,
this
problem
becomes
really
big
right
now,
just
I
don't
know
how
many
of
you
are
Gamers.
But
if
you
look
at
this
image,
it's
it's
a
character
from
Elden
ring,
which
is
one
of
my
favorite
games.
B
Now,
if
you
look
at
this
character,
he's
a
soldier
from
Raya
lucaria
and
this
person
he
has
an
armor
and
he
has
a
shield
right.
So
this
whole
set
of
armor
and
shield
together
on
Sandbox.
If
you
need
to
publish
this
armor
and
this
this
whole
set,
you
need
to
publish
five
nfts,
so
you
have
to
publish
helmet,
nft
jacket,
nft
shoes
and
ft
pants
and
shield.
B
If
you
want
to
do
it
on
decentral
end,
another
five
NF
is
on
walk
cells,
another
eight
nfts
on
somnium
Space,
another
five
nfts
and
here
as
I
said
I'm,
not
even
talking
about
the
games
I'm
just
talking
about
the
metaverses.
Now,
if
you
think
about
other
games,
there
are
going
to
be
even
more
effective
right
now
and
and
as
I
said
earlier,
if
you
think
that
each
of
these
nfts
has
1000
copies,
you
suddenly
have
23
000
different
token
IDs
on
the
blockchain,
and
none
of
them
are
connected
with
each
other.
B
It
is
completely
random
right
so
as
as
a
game
developer
as
a
game
publisher
or
as
a
designer
who
is
designing
this
armor,
you
have
to
maintain
so
many
things
at
the
same
time,
and
as
your
buyers
also,
you
have
to
buy
five
nfts
right.
That's
just
for
one
set
of
power
and
if
you
go
for
other
sets
of
armors,
you
have
to
buy
I.
Don't
know
10
15
20
nfts
out
there,
and
that
is
just
insane.
So
we
we
wanted
to
publish
this
on
Ft.
B
We
want
to
come
up
with
the
standard
to
just
take
the
first
step
towards
solving
this
problem,
and
now
imagine
just
to
give
you
this
just
to
help.
You
understand
the
scale
of
this
problem
with
Sebastian
from
sandbox,
who
is
one
of
the
co-founders.
He
himself
has
said
that
it
won't
be
just
a
metamorous.
It
would
be
a
Multiverse
right
right
now,
as
I
said,
we
have
five
six
big
metabosses
in
in
the
crypto
space
alone
and
in
the
future
you
are
going
to
have
so
many
Niche
meta
verses,
coming
up
right.
B
So
in
the
next
three
four
five
years,
I
think
there
will
be
dozens
of
metaverses
and
as
a
as
a
digital
digital
designer,
as
a
creator
of
a
variable
I
will
need
to
keep
on
publishing
my
nft
on
all
these
metaverses
and
none
of
them
will
be
connected,
but
you
know
there
has
to
be
a
better
way
and
I
think
we
are
proposed.
What
we
are
proposing
could
help
solve
this
problem.
B
So
what
we
are,
what
we
are
proposing
here
is
a
Multiverse
NFP,
and
this
is
going
to
be
a
top
level
entity.
So
you
could
consider
this
like
a
wrapper,
nft
or
a
proxy
nft
which
has
to
be
minted
by
the
buyers
and
this
nft.
It
will
represent
a
digital
asset.
So,
as
I
showed
you
earlier,
this
nft
equal
to
the
present
that
golden
jacket
as
a
whole.
Right
so,
let's
say
as
a
as
a
publisher.
B
So
if
you
want
to
buy
an
outfit
for
Aya,
Lupine
Soldier,
you
just
buy
this
Multiverse
nft
and
you
get
all
the
items
inside
that
NFP
I'll
talk
about
how
the
user
gets
those
items,
but
one
of
the
one
of
the
ways
in
which
all
the
other
items
on
the,
if
you're,
going
to
call
it
the
child
items.
The
child
entities
are
connected
with
this
Multiverse
nft
is
in
such
a
way
that
the
Multiverse
nft
kind
of
owns
all
these
child
nfts
or
what
we
call
as
delegate
nfts.
B
You
know
and
the
probability
of
the
standard
is
it
can.
It
is
very
extensible,
so
it
can
be
extended
to
as
many
nfts
as
possible
and,
let's
say
the
Raya
look
area
output
in
that
outfit.
You
can
have
as
many
as
many
items
as
possible
right
now
in
the
picture
that
I
showed
you,
we
just
had
a
shield,
but
you
could
also
have
a
sword
or
you
could
have
a
bow
and
arrow
or
a
crossbow
or
anything
like
that.
You
know,
and
now
this
could
be
applied
to
multiple
games
right.
B
So
if
you
look
at
the
standard
to
help
understand
the
standard
there,
you
need
to
understand
two
concepts.
The
first
is
the
Multiverse
energy,
which
is
the
top
level
nft.
The
rapper
nft
and
second,
is
the
delegate
nfts.
Now
the
delegate
nfts
are
the
five
nfts
or
the
eight
nfts
on
all
the
metaverses,
so
in
case
of
the
golden
jacket,
each
of
the
metaverses
will
have
an
nft
and
we're
calling
it
a
delegate.
B
Nft
so
you'll
have
a
delegate
nft
on
Sandbox
delegate,
nft
on
the
Central
and
five
delegate,
Industries
on
voxels
and
one
delegate
NFL
some
namespace,
for
that
example,
and
these
delicate
nfts
are
really
an
incarnation
of
this
digital
asset.
These
rfts
may
or
may
not
be
related
to
each
other,
that's
okay,
but
what
we
are
trying
to
do
is
we
are
trying
to
establish
the
relationship
between
these
nfts
at
the
top
level.
So
since
all
these
delegate,
Industries
are
owned
by
the
Multiverse
energy
at
the
top
level.
B
In
that
way,
you
can
establish
a
relationship
between
these
nfts
and
they
are
composable
as
well.
So
each
nft
can
exist
on
its
own
can
exist
as
a
part
of
a
bundle
or
you
know
it
can
exist
in
multiple
ways
like
that
now
just
to
go
into
slightly
more
technical
details.
If
you
look
at
the
interface
of
this
proposal,
the
first
thing
that
we
have
in
this
interface
is
the
delegate
data.
B
So
when
you're
creating
a
Multiverse
nft,
you
need
to
define
the
delegates
that
are
going
to
be
a
part
of
this
Multiverse
nft.
You
know
and
that's
why
we
have
this
truck
and
you
can
have
an
array
of
this
stuff,
so
this
truck
delegate
data
it
contains
the
contrite
address,
so
the
contract
address
essentially
is
the
address
of
the
contract
on
on
decentraland,
for
example
or
sandbox.
B
Then
you
have
a
token
ID,
which
is
the
ID
of
this
token,
on
on
decentral
and
or
any
of
the
metaverses.
You
have
the
quantity
so
how
many
of
these
nfts
exist,
and
you
have
a
state
called-
is
abundant,
so
essentially
any
delegate
nft
can
exist
in
either
of
the
two
states.
It
can
be
bundled
or
it
can
be
unbundled.
So
we
have
a
Boolean
for
that
and
we
also
have
a
field
called
owner
address
to
make
sure
that
we
track
the
owner
of
this
delegate
properly.
B
Then,
when
you
are
actually
creating
a
Multiverse
nft
or
when
you
are
minting
the
multiversion
Ft,
it
is
done
by
calling
this
function
called
init
bundle.
So
when
you
call
init
bundle,
you
have
to
send
the
array
of
this
delegate
data
struct
in
which
you're
sending
all
these
properties
that
we
talked
about
earlier.
B
So
you
send
an
array
of
these
delegate.
Nft
data
and
init
bundle
function,
will
mint
a
new
Multiverse
nft
right
and
now,
when
you're
minting
a
new
Multiverse
nft.
What
you're
doing
is
you're
defining
the
delegates
that
are
going
to
be
a
part
of
this
Multiverse
energy,
but
when
it
is
minted,
this
nft
is
going
to
be
empty,
so
it
won't
have
anything.
It
will
just
be
another
nft
at
the
top
level.
It
won't
have
anything
yeah.
Ideally,
the
contents
of
this
nft
should
not
be
changed.
B
But
again
the
authors
or
the
implementers
of
this
EIP
have
have
an
option
to
do
that.
They'll
just
have
to
make
sure
that
it
is
secure
and
you
you
might
have
some
edge
cases
right.
So
if
you
keep
changing
the
delegate
Properties
or
the
delegate
nfts
in
this
multiversity,
you
might
have
some
edge
cases
where
you
know
one
nft
can
go
from
one
owner
to
another.
You
just
need
to
make
sure
that
all
those
concerns
are
at
risk
when
you
are
implementing
this
in
a
CIP.
B
B
First
of
all,
you
actually
need
to
approve
all
these
delegate
entities
to
this
Multiverse
and
FD
contract,
and
when
you
call
the
bundle
function,
it
will
transfer
from
from
the
contract
of
this
of
this
delegate
and
actually
to
this
contract.
So
what
will
happen
is
now
this
nft,
this
Multiverse
nft
will
own
all
of
these
delegate
nfts.
So,
in
a
way,
what
you're
doing
is
you're
passing
the
ownership
and
the
you
know
the
relationship
from
the
individual
metaverses
to
the
top
level
electric,
which
is
the
delegate
nft,
sorry,
which
is
the
Multiverse
energy.
B
So
this
bundle
function
takes
an
array
of
the
delegate
data
struct.
It
takes
the
Multiverse
to
open
ID.
So
essentially
it
makes
sure
that
these
delegates
are
going
to
the
actual
intended
Multiverse
nft
and
it
also
takes
an
owner
address.
This
is
obviously
an
external
function
and
it
will
transfer
the
nfts
from
the
metaverses
to
this
Multiverse
energy,
and
this
this
function
is
quite
versatile.
You
can
actually
bundle
partially
as
well.
B
You
know
so,
let's
say
in
our
example
of
the
golden
jacket:
we
initialize
a
bundle
or
we
initialize
a
Multiverse
nft
with
eight
delicate
nfts,
but
you
can
call
the
bundle
function
by
sending
only
three
nfts
or
four
nfts
doesn't
matter.
The
maximum
you
can
go
is
eight,
but
you
can
bundle
less
than
that
as
well.
B
And
then
the
last
important
function
here
is
unbundle.
So
when
you're
unbundling,
the
nfts,
in
that
case,
you
you're
again
sending
an
array
of
the
delegate,
data,
struct
and
you're,
sending
a
Multiverse
token
ID.
So
you
need
to
make
sure
that
the
correct,
correct
multiversity
is
being
unbundled
in
this
case.
What
happens
is
so
now,
then,
why
do
we
have
an
unbundle
function
in
the
first
place
right?
So
let's
take
the
example
of
the
golden
jacket.
Again,
you
have
eight
nfps
for
the
golden
jacket
on
four
metaverses.
B
Let's
say:
I
buy
the
Multiverse
energy
and
I
get
the
golden
jacket
on
four
meta
versus
simultaneously,
but
in
this
case
I'm,
not
a
big
fan
of
let's
say
zombies
or
I'm,
not
a
big
fan
of
voxels
right
and
I.
Don't
want
to
keep
those
energies,
so
what
I
could
do
is
I
could
unbundle
those
injectories
from
this
Multiverse
energy
and
I
can
sell
them
on
the
secondary
Marketplace.
B
B
Now,
if
you
look
at
the
use
cases
for
this,
so
we
believe
that
one
of
the
fundamental
use
cases
is
digital
variables
right.
So
there's
a
big
physical
movement
going
on
right
now,
physical
I!
Don't
like
this
word
but
physically,
we
like
to
call
it
like
physical
to
digital.
You
know-
and
you
have
a
lot
of
fashion
brands
who
are
exploring
digital
close
in
the
upcoming
metaverses,
and
you
have
big
Brands
trying
to
do
this
right.
B
If
you
look
at
sandbox,
you
have
some
of
the
really
large
Brands
like
I,
don't
know
Gucci
Prada
these
these
brands
are
buying
land.
They
are
actually
exploring
creating
digital
fashion
items
there
you
know,
so
we
believe
that
this
could
be
a
great
use
case
for
this
EIP
and
the
second
I
think,
which
can
which
can
really
be
a
game.
B
Changer
is
in-game
assets,
so,
in
the
earlier
example,
I
showed
you
an
intersection
between
gaming
and
fashion
right,
so
the
armor
set
that
you're
buying
in
Elder
ring,
for
example,
that
is
nothing
but
a
digital,
nothing,
but
your
digital,
close,
your
digital
variables,
right,
there's
also
another
example
right
where
you
have
these
fashion
brands,
who
could
create
clothes
and
items
and
variables
for
your
game.
Authors,
for
example,
right
so
there's
an
intersection
between
variables
and
between
games
and
I.
B
Think
one
of
the
best
examples
for
this
is
in-game
assets
like
your
weapons
and
your
Shields
and
your
you
know
your
potions
and
all
those
things
now
imagine
there
are.
There
are,
let's
say
two
or
three
games
who
have
partnered
together
and
you
just
you
meant
like
one
gun
or
one
rifle,
and
this
one
rifle
you
can
start
using
it
in
multiple
games.
B
I
think
that's
going
to
be
a
game
changer
because
as
a
gamer
as
a
buyer
of
these,
these
things
I
can
just
buy
one
gun
and
I
can
use
it
all
across
the
family
of
those
games
right.
So,
for
example,
if
you
think
about
a
futuristic
way
where
all
the
all
the
big
titles
start
adopting
not
this
EIP,
but
they
start
adopting
nfts.
In
that
case,
let's
take
an
example
of
Assassin's
Creed
or
let's
take
an
example
of
the
whole
from
software
games
right,
so
you
have
held
in
the
rain.
You
have
Demon
Souls.
B
You
have
all
these
other
games
now.
Imagine
if
I
buy
a
sword
in
Assassin's,
Creed
and
I
can
use
it
across
all
the
Assassin's
Creed
games.
That's
going
to
be
quite
cool,
or
if
you
are
talking
about
the
Call
of
Duty
franchise,
Call
of
Duty
family.
If
you
buy
one
one
rifle
like
a
sniper
rifle
and
if
you
can
use
it
across
all
of
the
Call
of
Duty
games,
I
think
that's
going
to
be
a
game.
Changer
again,
we
are
still
way
off
from
the
rate.
B
I
think
it
will
take
another
10
years,
maybe
eight
or
ten
years,
for
these
games
to
embrace
it
if
it
happens,
but
I
think
blockchain
games
that
already
exist
and
that
are
already
being
built,
I
think
they
are
a
great
use
case
for
this
this
card
of
an
example.
You
know
and
Beyond
this
not
just
wearables
and
not
just
games.
You
can
also
use
this
standard
for
nft
file
and
you
know
you
can
use
it
hostaking.
You
can
bundle
different
things
together.
Have
some
loyalty
points?
Loyalty
Rewards?
B
You
know
coming
off
of
those
nfts,
so
you
can.
You
can
do
a
lot
of
things
right.
So,
for
example,
you
you
own
I,
don't
know
three
golden
jackets.
You
can
bundle
them
together
into
one
Multiverse,
nft
and
I.
Don't
know
the
metaverses
could
start
giving
you
some
loyalty
points
for
that.
So
yeah
there's
a
lot
of
applications
for
this
and
yeah
I
think
the
you,
the
community,
could
find
even
more
applications
and
use
cases
Beyond
this.
B
These
are
just
some
of
the
use
cases
that
we
thought
about,
but
yeah
I
think
it
could
be
used
in
multiple
other
scenarios
as
well.
Yeah,
that's
pretty
much
it.
If
you
want
to
contact
us,
you
can
contact
me
go
around.
You
can
also
contact
my
other
co-authors,
kimraj
and
nikhil.
They
are
on
Twitter
as
well
yeah.
Any
questions
on
this.
A
So
yeah
amazing,
this
presentation
was
great
thanks
for
sharing
this.
With
all
examples,
it
made
a
lot
of
sense
to
relate
the
proposal
and
the
term
physical
I
heard
it
for
the
first
time,
but
I
believe
we
kind
of
discussed
this
in
the
past
Peep
and
eat
meeting,
which
was
for
EAP
5496,
and
we
were
taking
some
gaming
examples.
So
thank
you
for
the
talk
and
yeah
I
will
open
the
platform
for
anyone
to
have
questions
here.
Yeah.
C
Thanks
for
that
growing
I
love
the
presentation
really
impressive.
I
I
hadn't
read
the
EIP
before
this
call,
but
I
think
you
explained
it
quite
well.
There
I
I
had
two
questions.
Actually
so
I'm
kind
of
new
to
the
whole,
like
Multiverse,
metaverse,
stuff
and
like
I
I,
definitely
know
the
nfts
are
going
to
play
some
role
in
that
I
guess
like?
Is
there
an
employee
like?
Are
there
any
implicit
assumptions
being
made
in
this
EIP?
So
what
I
mean
is
like?
C
Does
this
contract,
like
the
delegate
contract,
basically
get
deployed
on
me
internet?
Does
it
matter
what
China
gets
deployed
on,
because
I'd
assume
that
a
lot
of
these,
like
somnium
space
and
decentralized
use
their
own
chains?
So
it's
kind
of
like
a
multigen
world
right?
Are
we
just
assuming
that
we
deploy
this
delegate
contract
onto
mynit
or
am
I
missing
something
there.
B
No,
no,
that's
a
great
question.
That's
a
great
question!
So
yeah
we
have
thought
about
implementation
and
what
we
believe
is
that,
right
now
this
is
possible.
So
so
we
can
use
this
standard
on
the
same
blockchain
right.
So
it
could
be
polygon.
It
could
be
ethereum,
it
could
be
any
evm
chain.
Any
l2l1
doesn't
matter
right,
so
it
could
be
used
on
any
of
those
blockchains
right
now
we
haven't
thought
about
how
to
make
this
multi-chain.
B
Maybe
that
could
be
future
work
on
this
yeah
but
I
think
on
the
same
chain.
You
can
do
it
across
multiple
platforms
across
all
the
metaverses
and
what
I?
What
I
know
is
all
these
metaverses.
They
are
coming
on
polygon
now,
so
they
are
doing
a
lot
of
transactions
on
polygon.
It's
a
bit
mixed,
you
know,
so
they
started
with
ethereum
mainnet
and
now
they
are
moving
to
polygon,
most
of
them,
so
yeah
that
needs
to
be
worked
out.
Definitely
yeah.
C
Yeah
I
mean
that
makes
sense,
because
I
was
I
was
going
to
ask
like
how.
So
if,
if
I'm,
if
I
own,
the
gold
jacket,
like
you
said
and
then
I
want
to
sell
it
at
some
point
like
how
does
the
marketplace
is
know
where
to
look
for
the
delegate
contract
but
but
you're
saying
that
that
they
kind
of
have
that
information
right
because
they
know
where
some
new
space
is
deployed
or
where
decentraland
is
deployed,
so
they
can
kind
of
just
like
intuitively
know
exactly.
B
C
B
C
So
and
then
just
one
more
question:
I
guess,
like
it's
kind
of
split
into
two
parts,
so
I
was
wondering
who
actually
like
deploys
this
contract
and
then
also
does
the
deployer
of
the
contract
have
an
expectation
that
they
shouldn't
really
unbundle
some
nfts,
because
so,
let's
take
the
gold
jacket,
for
example.
So
if,
if
I
deploy
that
contract
and
then
bundle
the
all
of
the
nfts
and
the
various
metaverses
into
that
contract
and
then
later
I
come
along
and
it
like
on
bundle,
insomnium
space,
gold,
jacket.
B
C
B
Yeah,
no,
no,
that
those
are
great
questions
so
addressing
the
first
question
who
who
deploys
the
contract
I,
think
that
could
be
the
creator
of
this
golden
jacket
or
the
designer,
or
essentially
the
seller
right.
So
now,
let's
take
a
hypothetical
example,
h,
m
or
Zara:
they
are
coming
up
with
a
new
design.
Nice
nice
shiny
golden
jacket
and
they
want
to
create
a
digital
variable
for
this.
B
B
Then,
coming
to
the
second
part:
yes,
so
that's
where
it
gets
tricky
so
yeah
we
understand
right.
So
let's
say
you
buy
this
jacket
from
Zara
for
I,
don't
know
200
and
you
just
lose
one
fourth
of
the
value
right.
So
now
it's
only
worth
150
because
you
can
use
it
only
on
three
metaverses
right.
If
you
unbundle
this
on
your
space
thing
but
yeah
like
we
understand
it,
and
we
really
want
to
want
to
leave
it
to
the
implementers
right.
B
So
as
someone
who
is
implementing
the
standard,
you
can
choose
not
to
have
the
unbundle
function
or
you
can,
you
can
even
make
it
Soul
bound.
Actually
so
I
was
discussing
with
Puja
earlier.
What
you
could
do
is
you
could
make
all
of
these
tokens,
including
the
Multiverse
nft
token
Soul
pound.
So
you
can
just
stop
the
transfers
from
this
and
that
could
actually
open
up
some
really
interesting
applications
right,
yeah,
I.
C
B
C
B
B
C
B
C
B
A
Thank
you
and
I
have
a
few
more
questions
on
that
that
we
have
already
collected
so
probably
I'll
take
a
few
of
them,
because
you
have
partially
answered
some
of
them.
We
were
talking
about
Soul,
bound
nft
and
as
per
the
blog,
that
is
added
in
The
Fellowship
of
ethereum
magician
thread
as
an
additional
resource
to
understand
this
proposal.
This
proposal
is
tangential
to
Soul
bound
nft,
and
it
also
provides
the
flexibility
to
convert
into
Soul
bound
token.
You
did
talk
about
owners,
buying
and
selling
flexibility,
so
yeah.
B
Yes,
yes,
no
absolutely
so,
as
I
was
talking
to
you
earlier
Puja,
so
the
thing
is,
we
have
left
the
implementation
open
on
on
purpose
right.
We
want
this
to
be
extensible,
we
want
the
standard
to
be
extensible
and
hence
when
you
are
essentially
implementing
this
interface
when
you're
creating
this
contract
in
the
init
bundle
function
or
even
in
the
unbundle
function,
you
can
actually
add
some
some
constraints
right.
So
you
can
make
sure
that
when
you
create
the
bundle,
when
you
bundle
the
nfts,
you
can't
really
maybe
remove
them.
B
So
you
can't
even
unbundle
them
or
you
can
transfer
them
to
someone
right.
So,
even
at
this
level,
at
the
Multiverse
and
ft
level,
the
top
Nifty
level
you
can
just
remove
the
transfer
function.
You
know
implementation
again.
There
are
some
very
nice
implementations
for
soul,
bound
tokens
that
the
community
is
coming
up.
Just
removing
the
transfer
function
is
a
very
naive
implementation,
but
what
I'm?
What
I'm
trying
to
say
is
that
is
possible.
So
you
could
make
this
token
a
soul
bomb
token,
which
is
which
is
quite
cool.
B
You
know,
and
it
can
open
up
a
few
more
different
possibilities
right.
So,
for
example,
if
you
go
to
the
in
to
this
armor
right
in
case
of
this
Raya,
lucaria,
Soldier
or
yeah-
something
like
this-
let's
say:
you're
playing,
Elden
ring
or
you're
playing
any
blockchain
game.
For
example,
some
of
these
items
are
accessible
only
when
you
go
to
that
certain
level.
You
know
you
need
to
be
level
30
level
40
and
you
need
to
go
to
this
place
and
only
then
this.
You
know
this
item
opens
up.
B
A
D
One
of
the
issues
with
wrapping
base
tokens
is
that
you
lose
direct
access
to
those
tokens
so,
for
instance,
mooncats
you
can
change
the
name
ethereal
tiles.
You
can
change
the
name,
but
once
you
put
it
in
a
wrapper
like
this,
so
you're
saying
that
the
wrapper
that
holds
these
you
know
eight
different,
nfts
or,
however
many
would
have
to
support
the
changing
of
that
mooncat
name,
which
has
been
yeah.
B
So
that's
a
great
question:
actually
we
we
have
thought
about
this.
So
actually,
if
you
go
to
the
EIP
on
the
website,
we
have
a.
We
have
a
very
new
implementation
of
this
AIP
and
in
that
implementation,
the
way
we
are
doing
it
is
we
are
just
transferring
the
ownership
from
the
owner's
wallet
and
then
the
ownership
goes
to
this
Multiverse
nft
contract.
B
You
know
so
in
that
case
we're
not
really
changing
the
delegate
contracts
right
the
base
and
everything
contract
we're
not
changing
anything
there,
we're
just
transferring
the
ownership
there
yeah
and
now,
when
you
unbundle
it
back,
so
you
get
back
it.
You
get
it
back
in
your
wallet
right
and
in
that
case,
in
the
case
of
moon
cards,
for
example,
when
you
bundle
you
cannot
change
the
name,
but
when
you
unbundle
you
get
it
back
and
you
can
again
change
the
name.
So
it's
completely
up
to
the
owner
of
this
nft
yeah.
D
B
Yes,
that's
that's
really
interesting
and
that
actually
now
now
actually
just
let
me
extend
this
example
into
the
in-game
assets
and
that's
where
actually,
that's
actually
one
of
the
challenges
for
implementers.
You
talked
about
zip
and
unzip
right
now.
Let's
even
extend
this
further,
let's
think
about,
let's
say
a
gun
or
a
sword
right
now,
if
you're
buying
one,
let's
say
a
sword
and
you
want
to
use
it
across
multiple
games
now
the
way
in
which
this
sword
actually
works.
B
It
could
be
different
in
multiple
games
right,
similar
to
your
zip
and
zip
example.
So
yeah,
that's
that's
one
challenge
with
this
I
think
and
we
need
to
figure
it
out
how
we
can
Implement
that
challenge
move
yeah.
We
don't
have
an
answer
to
that.
We
could
potentially
so
the
rapper
nft
could
potentially
Implement
that.
But
you
know
at
the
end
of
the
day,
there
are
just
limitations
right.
So
how
many
metaverses?
Can
you
cater
to?
How
many
games
can
you
cater
to
right?
B
D
B
Their
original
writing
of
the
rapper
it
depends,
so
it
could
be
Gucci
themselves
or
you
could
have
a
platform
which
actually
implements
the
standard.
Actually
we
one
of
my
my
other
company,
where
I
work
at
indoors,
we
are
creating
a
project
called
meta
link
where
we
are
implementing
this
EIP
and
we
are
creating
like
a
NFP
creation
platform.
You
know,
like
nft,
launcher
variables,
launcher
where
we
are
implementing
this,
so
Gucci
can
come
and
use
that
platform
to
launch
their
collection.
A
B
Yes,
yes,
absolutely
so
again,
we
have
standard
open,
saplin
interfaces
for
ERC
721
tokens,
but
you
know
in
case
of
bundling
and
unbundling
when
you're
sending
your
nfts
or
when
you're
unbundling
them,
in
that
case,
you're
calling
an
external
contract
and
there
could
be
issues
with
re-entruency
attacks
right.
So
you
cannot
assume
that
the
delegate
contract
is
always
a
secure
contract.
When
you
call
the
transfer
from
function
in
the
delegate
contract,
it
could
have
some
malicious
code
and
you
don't
know
what
could
happen.
B
So
it's
very
important
for
the
implementers
of
the
Multiverse
nft
to
make
sure
that
the
delegate
contracts
are
safe.
Yeah,
that's
one
and
second,
is
again
personally
I've
been
writing
smart
contracts
right
for
a
while
and
I,
don't
like
to
keep
anything
in
the
smartphone
right,
be
it
ether
or
any
cryptocurrency
or
any
nfts
I,
usually
immediately
put
it
out
and
keep
it
in
a
hardware
wallet
right,
but
in
this
case
inherently
this
contract.
These
Multiverse
nfts
are
going
to
own
all
the
delegate
entities.
So
this
Multiverse
nft
contract
itself.
B
It
becomes
like
a
big
big
Target
for
hackers,
right
so,
let's
say
Gucci
or
Prada.
They
they
start
selling
golden
jackets
for
thousand
dollars
each
two
thousand
dollars
each
and
I.
Don't
know
if
you
get
100
000
people
using
these
jackets
right.
Okay,
that
becomes
a
Target
immediately,
so
I
don't
know.
D
A
A
My
next
question
is
about
a
proposal,
so
we
observed
in
a
comment
on
the
discussion
to
page
about
an
alternate
proposal:
eip4955
that
is
a
vendor
specific
metadata
extension
for
nft
tokens
that
basically
suggests
adding
a
new
field
to
nft
metadata,
to
store
vendor
specific
data
for
our
users.
Community.
Will
you
explain
the
difference
between
the
two
and
does
EIP
5606
hold
any
advantage
over
the
other,
or
are
they
independent
of
each
other?.
B
Yeah
yeah
so
as
I
see
it
I
think
these
four
VIPs
are
kind
of
independent
of
each
other.
They
are
trying
to
solve
the
same
problem
so
when
I
read
that
EIP
and
I
went
through
their
motivation
and
all
these
things
they
are
trying
to
solve
the
same.
A
similar
problem
we're
just
making
sure
that
these
assets
are
compatible
between
the
metaverses,
but
the
way
they
are
doing
it
is
they
are
adding
one
more
one.
More
field
called
namespace
to
the
metadata.
Frankly,
I'm
not
really
sure
how
these
projects
are.
B
I,
don't
know
if
they
expect
the
meta
buses
to
adopt
this
new
standard.
So
I
think
that
could
be
one
challenge
in
that
case,
because
making
metaverses
do
anything
that
will
take
a
few
months
to
one
year
or
even
two
years
right
and
that
if
the
standard
is
like
a
really
popular
standard,
but
in
case
of
erp5606,
the
thing
that
we
are
proposing
metaverses
don't
need
to
do
anything
at
all.
Literally
it
is,
or
it
is
actually
up
to
the
creators
and
the
buyers
of
these
nfts
to
just
implement
the
standard.
B
And
you
don't
it's
completely
backwards,
compatible
metaverses.
Don't
need
to
change
anything
games,
don't
need
to
change
anything,
they
just
operate
the
way
they
are
and
the
creators
can
just
use
this
directly
and
another
differentiation
is,
while
that
other
standard
talks
about
metadata
itself.
We
are
talking
at
the
nft
level.
B
So,
yes,
assets
are
important
and
assets
need
to
be
in,
you
know
compatible
and
interchangeable,
but
we
are
actually
going
one
level
above
that
we
are
talking
about
nft
stem
cells
and
nfts,
so
essentially
our
nfts
our
standard
code,
Implement
that
standard
for
the
metadata.
So
in
a
way
it
could
be
compatible
in
a
way
it
could
be
separate,
yeah,
so
yeah
there's
some
definitely
some
synergies
there.
Let's
see,
let's
see
what
happens.
A
Definitely,
yes,
we
are
receiving
multiple
proposals
on
nft,
so
I
was
just
trying
to
get
some
clarification
here.
However,
that
proposal
is
also
in
the
draft
status
so
yeah.
We
look
forward
to
changes
which
is
coming
up
in
both
sides
and
whatever
is
being
supported
by
most
of
the
users,
probably
will
be
seen
in
the
final
status.
C
A
A
B
Yes,
yes,
no!
No,
that's
a
that's
a
great
question
as
well,
so
we
have
been
trying
to
do
some
naive
implementations
of
this
interface.
Definitely
the
three
of
us
and
I
think
this
is
almost
ready.
We
might
want
to
change
some
some
data
types
and
all
these
things
in
the
signatures
of
the
functions,
because
we
think
we
can
optimize
them
further,
so
we
might
make
one
or
two
comments
to
the
to
the
GitHub,
repo
and
I
think
from
there.
B
A
B
A
All
right,
I
have
one
last
question
about
the
eib
process.
Maybe
if
you
would
like
to
share
any
thoughts
on
the
current
process
or
if
there
is
anything
that
we,
the
cat
holders,
can
do
to
extend
our
health
to
upcoming
EIP
authors
in
terms
of
documentation
or
helping
proposal
reach
to
become
a
standard.
B
B
A
couple
of
EIP
editors
have
written
their
own
blogs
as
well
on
the
exact
steps
which
are
kind
of
similar
to
aib
one,
but
you
know
they're
quite
detailed
and
nice,
but
even
then
it
was
I
didn't
really
know
the
steps
on
how
to
take
it
to
the
draft
stage
or
to
the
review
stage
or
essentially
how
to
move
to
the
next
stage.
You
know
that's
still
a
little
bit
confusing
for
me
frankly,
but
what
helped
me
was
when
I
started
joining
those
calls.
B
So
you
have
those
bi-weekly
calls
and
those
who
are
really
good,
so
I
could
get
to
interact
with
the
EIP
editor
directly
and
that
was
really
helpful
and
actually
just
understanding
their
thought
process,
how
they
are
editing,
the
other
aips
and
what
they're
looking
for?
What
are
the
mistakes
that
helps
a
lot
so
yeah
documentation
is
great,
but
I
think
documentation
only
takes
us
to
like
80
percent
85
percent.
The
last
10
15
percent
are
still.
