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
Super
happy
to
be
here.
This
is
a
great
crowd.
Yesterday,
it
was
more
like
cultural
arts
focus.
Today,
it's
a
little
bit
more
technical
focused.
This
opening
talk,
I'm
gonna
do
is
a
survey
from
bottom
to
top
of
what
is
underneath
the
hood
on
nfts
and
so
the
audience
I'm
imagining-
and
I
don't
know
hopefully
this
is
who
you
all
are
is
folks
are
excited
about
nfts,
who
are
not
afraid
to
get
technical,
but
maybe
like
haven't
done
all
this
research
yourselves
yet
so.
A
Consider
this
to
be
like
the
tip
of
the
iceberg
of
the
different
points.
You'd
probably
want
to
get
deeper
on.
If
you
wanted
to
become
an
expert-
and
I
won't
do
slides
I'll
just
talk
through,
it
feel
free
to
stop
me
and
ask
questions
or
whatever,
so
I
can't
address
the
whole
ecosystem.
A
What's
going
on
with
solana
and
the
others,
so
the
core
of
an
nft
kind
of
like
at
the
the
very
smallest
component,
the
thing
that
makes
it
non-uh
fungible
is
the
token,
and
if
you
look
at
the
ethereum
virtual
machine
specification
and
all
the
you
know
things
you
can
run
on
it,
there's
a
bunch
of
different
kinds
of
tokens.
So
an
erc20.
That's
like
a
standard,
functional
token,
where
everyone
is
the
same.
It's
like
like
a
penny.
I
can
give
you
one
you
can
give
me
one
and
the
trade
is
even
erc.
A
If
you
understand
that
one
then
you'll
be
well
positioned
to
understand
erc
1155,
erc
1155,
the
quick
way
to
think
about
it
and
all
you
need
to
know
about
it,
for
this
talk
is
that
it
it
people
got
frustrated
that
if
you
wanted
to
do
something
in
a
smart
contract,
it
was
both
doing
erc,
20s
and
721s
you
couldn't
you
had
to
write
two
smart
contracts
and
coordinate
them,
and
so
they
came
up
with
1155,
which
lets
you
do
that
kind
of
stuff,
probably
also
you
know,
is
a
little
bit
more
challenging
to
get
fully
secure.
A
So
I
recommend,
if
you're,
going
to
be
learning
in
the
space
learn
on
721,
but
you
know
really
that
that's
not
your
first
step,
so
you'll
come
back
to
that
the
the
token,
so
that's
the
the
core
little
atom
of
your
nft.
The
token
doesn't
care
what
the
nft
looks
like
it
doesn't
care
about
the
metadata
associated
with
it.
Like
you
know,
it's
just
links
to
those
things
so
token
moves
around
on
the
blockchain.
That's
what's
actually
traded
the
blockchain
trades.
You
know
it
doesn't
care
that
it's
a
board
ape
or
not
it.
A
A
That's
a
pretty
simple
way
to
look
at
it,
not
always
right,
but
one
smart
contract,
one
collection,
kind
of
right
and
when
you
do
the
mint
operation
on
that
contract,
basically
it
just
takes
whatever.
The
next
number
is
the
nft
that
that
you're
minting
and
says
make
nft
number
33
or
whatever,
and
what
that?
What
that
does
creates
a
token
and
fills
in
these
two
important
fields.
A
So
if
you're
now
like
being
a
tech
creator-
and
you
want
to
get
into
this-
there's
like
three
main
approaches
to
dealing
with
the
smart
contract
side
of
it
and
they
all
have
their.
You
know
trade-offs
and
times
when
it's
the
right
choice,
the
easiest
one
and
the
one
you
probably
do
for
your
first
toy
nft
when
you're
just
figuring
it
out,
is
use
the
one
that
comes
with
your
marketplace,
that
you
decided
to
go
with.
A
And
so,
if
you're,
just
if
you
click,
ok
enough
on
wearable
or
openc,
you'll
get
an
nft
and
there
will
be
a
smart
contract
associated
with
it.
And
you
didn't
have
to
write
it
and
if
there's
bugs
in
it,
it's
probably
not
your
fault.
So
I
recommend
you
do
that
unless
you
want
the
bugs
in
your
smart
contract,
to
be
your
fault.
A
But
then
also
the
features
are
yours
to
choose,
and
so,
if
you're
serious
about
what
you're
kind
of
like,
maybe
it
would
be
the
difference
between
taking
like
like,
if
you're
serious,
about
just
the
way
it
looks
you
don't
really
care
about
the
digital
behavior
of
it
then
sure
go
with
one
of
the
pre-built
smart
contracts.
It's
probably
the
right
choice.
A
First
of
all,
unless
you
are
really
comfortable
with
this
and
like
have
maybe
written
security,
you
know
audited
code
before
you
probably
want
to
find
a
developer
who's
done
that
at
least
to
kind
of
like
shoulder,
surf,
what
you're
doing
and
tell
you
whether
or
not
you're
doing
it
right,
but
then
even
then
you're
still
deciding.
Am
I
using
a
high
level
builder
tool,
or
am
I
writing
my
smart
contract
from
scratch
and
a
high
level
builder
tool?
A
Is
going
to
be
built
by
somebody
who,
probably
you
know,
cares
about
it
even
more
than
the
developer?
Who
would
shoulder
surf
you
and
has
had
a
lot
of
code
review
on
the
individual
components,
but
then
you're
going
to
take
these
components
and
like
use
them
as
you
see
fit,
so
there
may
be
like
a
transfer
module
and
a
royalty
module
and
an
updates
module
and
maybe
combined
with
other
nfts.
Whatever
is
in
that
smart
contract?
You
know,
library,
toolkit
whatever
is
made
available
to
the
builder
software.
A
So
that's
going
to
allow
you
mostly
to
customize,
and
it's
going
to
make
it
a
little
bit
harder
for
you
to
shoot
yourself
in
the
foot,
because
at
least
at
the
individual
function
level
you're
going
to
be
using
audited
code
and
it
you
can
totally
compose
that
stuff
in
a
way,
that's
going
to
be
a
bad
idea,
but
at
least
you're
working
as
a
composer.
Not
like
writing
the
intricate
quick
links
all
the
time
that
they're
not
there.
That
could
happen
to
your
nft.
A
So
the
next
step
you
want,
then,
is
a
decentralized
solution
and
there's
a
bunch
of
them.
I
won't
get
into
them
too
much,
except
for
to
say
that,
like
a
lot
of
them
use
their
own
blockchain
to
track,
you
know
what's
stored
where
and
what
not
and
that's
one
way
to
do
it.
The
what
nft
storage
does
is
a
little
bit
different.
We
use
ipfs,
which
I
won't
tell
you
like
everything
about.
You
don't
need
to
know.
A
A
A
Then
it
doesn't
matter
who
gives
it
to
me
because
when
they
give
it
to
me,
I
can
verify
the
fingerprint,
and
so
essentially
I'm
asking
who
can
give
me
this
the
fastest,
instead
of
saying,
like,
I
sure,
hope,
the
place
that
has
this
is
open
for
business
right
now
and
it
allows
you
to
make
your
own
backups.
It
allows
you
to
take
your
you
know.
Same
content
addressed
information,
your
fingerprinted
files
and
put
them
in
like
a
centralized
cloud.
A
If
you
want,
or
on
your
local
machine
or
in
a
distributed
storage
network
like
filecoin
and
so
at
nft
storage,
we
do
all
of
the
above.
Basically,
when
you
upload
nft,
metadata
or
asset
file,
we
store
it
in
all
those
places
we
store
it
in
filecoin.
We
store
it
in
s3
we
pin
it
to
pinata,
which
is
another
ipfs
storage
service,
and
so
it
kind
of
since
we're
asking
for
these
files
by
fingerprints.
A
We
like
to
call
this
storage
layer
maximalism.
If
you
spent
like
a
hundred
thousand
dollars
on
an
nft,
you
sure
would
want
to
have.
You
know
50
worth
of
backups
worldwide
on
that
and
when
you're
doing
this
fingerprint
based
identifiers,
there's
no
technical,
you
know
hiccups
or
anything,
stopping
you
from
doing
that.
A
So
now
that
you
know
about
these
fingerprint
links,
you
can
see
why,
on
chain,
you'd
want
to
have
a
fingerprint
link,
a
content
identifier.
Instead
of
a
centralized
link
because,
like
let's
say
you
had
a
link
to
your
json
file
with
all
those
you
know,
curly
braces
and
your
description
and
stuff
runs
through.
That
function
gets
its
fingerprint.
A
You
put
that
on
the
on
the
blockchain
and
then
anyone
who
comes
to
read
it
can
just
ask
the
network
for
the
fingerprint
and
get
the
fastest
result
back,
and
if
the
original
server
was
on
went
away,
they
probably
won't
notice
and
all
that
good
stuff,
so
you're
also
going
to
want
to
do
that
for
the
image
files
or
the
movies
or
the
you
know,
svg
files
or
html
programs
or
whatever
that
constitute
the
content
of
your
nft
and
that's
also
the
same
mechanism.
A
So
you
have
your
image
file
when
you
upload
it
to
nft
storage
or
to
any
other
ipfs
host,
or
if
you
run
an
ipfs
node
locally
on
your
machine.
You
can
process
it
there
and
get
that
content
identifier
and
put
that
into
your
metadata
file.
So
now,
you've
got
the
token
which
is
managed
by
the
blockchain.
A
It's
essentially
immutable.
It
only
changes
when
the
blockchain
allows
it
to
change.
Then
you
have
a
link
to
metadata
which,
if
it's
one
of
these
fingerprint
links,
that
also
can't
change
it's
immutable,
and
so
that
then
now
can
contain
links
to
the
images
and
those
images
are
fingerprint
links
also,
so
they
can't
change,
and
I
like
to
call
that
whole
system
that
that
nft
is
chain
locked
like
the
blockchain,
is
managing
its
state
and
the
no
one
can
go
and
mess
with
it.
A
It's
not
on
chain,
so
you're
not
paying
that
huge
storage
cost
to
store
it.
You
know
on
the
actual
blockchain
itself,
which
is
prohibitively
expensive
for
all,
but
the
smallest
nfts
and
you
get
essentially
the
same
correctness,
guarantees
there's
you
know
it's
physically
possible.
I
think
the
only
difference
between
having
it
embedded
into
the
blockchain
and
using
a
fingerprint
link
is
that
it's
physically
possible
for
the
fingerprint
link
to
not
resolve
right.
A
So
most
nfts
are
static.
They
don't
change
it's
the
image
that
you
bought
when
you
bought.
It
stays
there,
but
people
are
getting
more
creative
with
dynamic
nfts,
and
it
raises
questions
because
back
to
the
point
about
centralized
urls
one
of
the
easiest
ways
to
do,
it
would
be
for
the
dynamic
nft
creator
to
have
like
mydynamicnft.com
the
image
file,
and
then
you
know
change
it
as
like.
A
Let's
say
they
wanted
to,
I
don't
know,
depict
sunrise
and
sunset
appropriately
for
your
time
zone
or
whatever
they
could
just
be
always
changing
that
file,
and
every
time
you
load
the
nft.
It's
different.
That
raises
all
kinds
of
questions
with
like
your
downstream.
You
know,
galleries
and
hosts
like.
Are
they
gonna
like
keep
a
copy
for
performance
reasons
and
then
not
know
how
to
update
it
or
whatever?
A
Is
somebody
going
to
like
break
the
business
process?
And
now,
instead
of
a
sunset
for
your
pfp,
it's
just
broken
the
way
you
might
ameliorate.
That
issue
is
to
use
these
fingerprint
urls
again
and
then
to
have
a
clause
in
your
smart
contract
that
says,
oh
people
who
stand
in
this
relation
to
the
token
can
update
the
metadata
for
it.
So
maybe
the
creator
is
allowed
to
change
the
metadata
or
maybe
just
the
owner
is
allowed
to
change
the
metadata,
and
at
least
that
way
when
there's
a
change
like.
A
Oh,
we
got
a
new
version
of
the
image
it's
on
chain,
so
you
can
go
and
be
like
well.
That
happened
on
august
4th
and
before
that
it
was
the
old
style,
and
now
it's
the
new
style,
and
it's
like,
as
you
know,
the
way
we
expect
nfts
to
work,
then
there's
also
work
we're
doing
at
protocol
labs
and
on
the
nft
storage
team
around
having
like,
I
guess,
the
way
you
think
about
it
is.
A
A
There's
the
last
like
segment
that
I'll
get
into
in
a
second
here
is:
maybe
a
treat
for
the
artists
around
how
to
do
how
to
make
those
images
and,
of
course,
if
you're,
an
artist,
you
shouldn't
listen
to
me
because
you
know
how
to
make
images,
but
if
you
wanted
to
kind
of
like
fit
in
with
what
it
looks
like
in
the
ecosystem.
Right
now,
like,
let's
say
you
wanted
to
make
a
drop
of
5
000
profile,
photos
that
have
like
you
know,
characteristics
and
rarity
and
whatnot
and
kind
of
like
fit
into
that.
A
That
thing.
There's
all
kinds
of
tools
and
I've
been
looking
at
the
ecosystem-
a
lot,
I
guess
I'll
all
endorse,
not
as
the
only
one
I
would
use,
but
the
first
one
I
would
use
for
a
project
like
this
hash
lips.
They
do
these
great
youtube.
Tutorials
like
go
on.
There
watch
some
of
their
videos
download
their
code.
It's
you
know
clean
code
for
doing
all
the
stuff
that
you
really
shouldn't
have
to
do
as
an
artist
but
like
like.
A
Let's
say:
you've
got
a
photoshop
file
with
you
know:
six
different
layer
groups
and
20
variations
in
each
of
those
layer
groups.
They
have
a
script
that'll.
You
know
run
on
that
and
spit
out.
However
many
files
you
want,
you
know,
like
you,
can
stretch
it
to
10
thousand
or
five
thousand,
or
a
hundred
it'll
automatically
make
the
variations,
and
you
can
give
it
some
input
about
like
which
attributes
you
wanna
have
be
more
rare
and
whatnot.
A
So
hash
lips
is
also
good
for
when
that
process
is
done,
they've
got
code
that
will
create
all
the
metadata
files
for
you
and
help
upload
it,
and
so
I've
been
looking
really
closely
at
the
way
they
do
their
stuff,
because
theirs
is
kind
of
like
if
we're
step,
one
for
uploading,
your
nfts
and
like
listing
them
on
the
marketplace
to
step
two
first
making
them
is
step
zero,
so
they're
a
great
way
to
do
it,
obviously
not
the
only
way
to
do
it,
but
if
you
wanted
to
again
just
kind
of
like
learn,
what
are
the
moving
pieces
doing?
A
You
know
a
run-through
of
a
hash
lips
profile.
Photo
collection
build
even
with
their
example.
Data
is
a
great
way
to
see.
You
know
what
you're
going
to
be
dealing
with
when
you
do
yours
for
real.
A
So
that's
all
that
I've
really
got
for
content
super
happy
to
take
questions.
I'm
just
gonna
people
say
like.
I
should
just
repeat
it
again:
real
quick,
what
we
just
heard.
So
you
know
what
to
go.
Look
up
so
there's
tokens
specifically
erc
721
and
erc
1155
and
then
the
other
other
blockchains
have
other
stuff
there's
a
smart
contracts.
A
You
know
how
to
write
these
smart
contract
languages,
your
metadata,
that's
the
thing
that
you
know
says
the
name
of
the
the
nft,
the
collection,
it's
in
links
to
the
image
files.
That's
again
like
one
of
the
it's
not
on
chain,
it's
linked
from
the
chain.
A
If
you
use
a
content
fingerprint
for
it,
then
I
like
to
call
it
chain
locked,
because
no
one
can
change
it
without
changing
the
chain
and
that'll
link
to
the
assets
and
images
and
if
they're
also
using
the
fingerprint
urls,
then
you
can
back
them
up
as
many
times
as
you
want
and
you
can
load
it
from
the
nearest
backup
or
the
fastest
backup,
and
I
guess
yeah.
This
is
a
really
fun
analogy
that
I
heard
from
jonathan.
I
think
I
think
juan
binet
originally
said
it.
A
But
okay,
so
let's
say
I
wanted
a
book.
Let's
say
I
want
to
catch
her
in
the
rye,
the
equivalent
of
getting
it
under
like
the
centralized
url
system
would
be:
oh,
okay,
yeah
they're
publishers
in
boston
and
they're,
open
from
nine
to
five,
so
when's
the
next
flight
to
boston
and
that's
kind
of
a
silly
way
to
get
a
copy
of
catcher
in
the
rye,
because
instead
we
can
use,
what's
essentially
like
the
fingerprint
and
look
it
up
by
its
isbn
and
get
it
from
the
nearest
bookstore.
A
So
that's
a
little
bit
what
how
you'll
be
able
to
access
your
content
when
you
use
these
content
identifiers
and
then
kind
of
the
the
last
point
being.
If
that
seems
rigid
to
have
content
that
is
locked
to
the
chain.
There
are
ways
to
move
forward
without
sacrificing
the
correctness
and
have
dynamic
content
on
chain.
It's.
You
know
it's
a
little
bit
more
challenging,
but
it's
getting
easier
all
the
time
and
then
yeah.
A
The
last
thing
I
mentioned
for
folks
who
are
who
want
to
generate
a
bunch
of
nfts
and
play
around
with
it,
see
what
it's
like
to
be
an
artist
on
the
side
of
the
equation.
Hash
flips
makes
great
tools,
even
if
you
just
download
their
default
tool-
and
you
know
press
yes,
the
whole
time
you'll
end
up
with
a
collection
of
nfts
that
are
generated
from
their
example.
A
Data
and
it'll
be
unique
because
right
like
there's
enough
example,
data
to
where
I'm
not
saying
you
go,
sell
them,
but
I'm
saying
that
would
be
really
a
good
start
for
a
developer
to
have
seen
it
before
or
for
an
artist
to
have
seen
it
before
before
they
go.
Do
their
own
so
yeah,
thanks
for
you
know
being
here,
and
it
looks
like
there's
some
questions.
C
Oh,
thank
you
sorry
yeah.
You
bet
so
and
of
course,
it
makes
sense
that
a
lot
of
the
focus
here
was
on
the
creation
of
art
and
you're
referencing.
You
know
where
you
would
storage
the
art
and
that
use
for
nfts,
but
I'm
curious
about
some
other
examples
you
might
want
to
point
to
when
we
think
of
say,
object,
capabilities
right,
it's
that
you
could
use
it
in
token
gated
communities
and
other
examples
like
this.
I
was
wondering
if
you
might
be
able
to
dive
in
on
that
a
little
bit.
A
Sure,
okay
yeah
now
we're
talking
about
use
cases
for
nfts
and
one
of
the
one
of
the
ones
that
got
popular
early
on
is
like
essentially
a
membership
card
for
a
club,
another
one
that
is
different
but
similar
is
like,
as
a
frame
on
your
profile
photo
to
prove
that
you
donated
to
something
and
so
those
those
use
cases,
I
think,
is
I
I
for
I'm
lucky
to
be
in
the
position
where
the
thing
inside
a
metadata
json,
not
my
problem
right
but,
like
I
said,
there's
gonna
be
like
the
four
fields
that
you
have
to
have
and
then
you
can
put
anything
else
in
there,
and
so
you
could
put
like
membership
type
or
you
could
put
you
know.
A
How
long
does
this
donation
get
recognized
for
or
any
of
those
things
and
then,
as
long
as
whoever's
reading
that
nft
understands
your
metadata
extension
and
how
to
deal
with
it?
You
can
do
that.
It's
simple!
If
it's
your
own
club,
like
you,
just
tell
the
bouncers
look
for
that
flag.
A
It's
a
little
bit
more
complicated
you'd
have
to
like
work
with
twitter
and
figure
out
if
they're
going
to
honor
your
expires
field
or
whatever
for
a
profile
photo.
But
there's
you
know,
there's
no,
no
one!
Stopping
you
from
adding
new
functionality.
It's
just!
Then
you
have
to
convince
the
rest
of
the
world
to
pay
attention
to
it.
B
One
one
more
question,
so
I
actually
like
the
example
of
the
let's
say
you
made
a
donation.
Then
you
got
the
you
know
nft.
You
know,
there's
a
there's,
a
problem
there,
where
you
could
transfer
this
nft
to
somebody
else
or
you
could
sell
it
to
somebody
else.
So
it's
gonna
prove
for
somebody
else
that
they
did
something
that
they
didn't
do
how's,
that
being
solved
in
the
nft
world.
Okay,.
A
B
Yeah,
but
somebody
may
also
have
multiple
wallets
and
may
want
to
move
between
their
own
wallets
right,
not.
A
That's
shaped
like
most
of
the
hard
problems
in
nfts,
which
I
think
are
more
cultural
than
technical
like
there's,
not
there's,
not
a
technical
solution
really
to
saying
like
just
because
it
looks
like
a
board
ape
doesn't
mean
it's
a
board
ape.
You
have
to
actually
follow
the
transactions
back
and
make
sure
it
originated
with
the
right
collection,
and
so
as
people
come
to
understand
what
I
mean
really
like
that
token.
We
talked
about
this
history
of
ownership
of
nfts.
A
That's
where
the
really
interesting
power
of
them
comes
from
is
like
a
thing
that
looks
like
a
board
ape,
but
isn't
really.
The
only
difference
is
how
it
got
here.
It
could
be
the
exact
same
file,
and
so
it's
that
history.
That
is
where
the
value
comes
from,
like
two
identical
squiggles,
but
one
of
them
was
held
by
a
celebrity
right.
They're
gonna
have
different
kind
of
different
values
and
that
same
thing
is
going
to
apply.
I
think,
like
pretend
we
were
all
you
know.
A
D
Can
you
talk
a
little
bit
about
pros
and
cons
of
nft
collections
going
multi-chain
like
I've
seen
some
artists?
They
most
artists
just
seem
to
pick
one
chain
like
polygon,
ethereum
solana,
but
then,
if
you're
trying
to
reach
maybe
assets
that
are
like
in
other
chains.
You
know
what
are
some
of
the
pros
and
cons
of
going
multi-chain.
A
Oh,
that's
a
really
good
question
I
like
might
not
really
have
an
authoritative
answer.
I
know
that
multi-chain
is
going
to
heighten
the
sense
of
ownership
of
a
thing.
It
just
gives
you
more
control
over
it.
Okay,
in
the
same
way
that
like
it,
would
be
kind
of
silly
to
buy
a
digital
object
from
facebook.
A
A
I
see
the
chains
as
kind
of
like
scenes
right,
like
the
art
scene
on
the
taizos
chain.
Just
has
like
a
different
feel
from
the
art
scene
on
the
ethereum
chain
or,
like
you
know,
the
what
you
see
on
the
galleries
on
magic
eden
looks
different
from
what
you
see
on
the
galleries
on
openc
and
if
they're,
then
the
chains
are
like
starting
to
act
as
these
cultural
signifiers.
A
So
if
you're
gonna
like
cross
chain
on
a
polygon
like
you
might
do
it
for
an
artistic
reason,
yeah,
but
actual
just
cross-chain
trading
or
whatever,
I
imagine
your
your
defy
and
your
fungible
token
wizards
are
going
to
get.
You
know,
get
that
figured
out
and
then
nfc
will
ride
on
those
rails.
A
A
Right,
yeah,
there's
no
real
way
to
recall
those
fingerprinted
items
from
the
web.
You
could
you
could
stop.
You
know,
subsidizing
their
storage.
You
could
delete
all
your
copies,
but
if
somebody
was
a
big
fan
or
if
it
made
it
onto
somebody's
watch
list
of
you
know
objects
they
want
to
keep
a
clone
around
of
then
that's
there's
nothing
really!
You
can
do
about
it.
It's
public
data
there's
a
whole
question
around.
A
You
know
how
do
you
manage
private
data
in
a
content
address
network
and
that
essentially
means
wrapping
it
in
encryption,
so
the
encrypted
thing
can
become
public.
So
if
you
it
is,
I
think
again
like
a
cultural
problem.
If
you
really
can't
delete
data,
you
know
the
most
you
can
do
is
like
refuse
to
replicate
it
right,
there's
like
moderation,
lists
that
are
replicated
and
that
data
doesn't
get
replicated
so
there's
systems
in
place.
But
it's
not
like
it's
not
like
a
eager
delete
that
crawls
the
whole
network
and
issues
delete,
commands.
E
Hey,
I
wonder
if
you
could
talk
more
about
the
dynamic
nfts
and
especially
like
I
guess,
like
setting
a
range
or
guardrails
around
like
what
could
possibly
be
changed
and
maybe
that
the
technical
element
of
that,
and
especially
as
it
relates
to
you,
know,
a
lot
of
what
we're
seeing
in
gaming
space
and
you
know,
use
of
actual
use
of
those
nfts.
A
Yeah,
okay,
so,
first
of
all,
I
think
that
you
can
get
dynamic
behavior
from
immutable
nfts
in
lots
of
interesting
ways
that,
like
aren't
too
high
stakes
as
far
as
like
be,
if
there's
a
centralized
component,
it's
not
necessarily
a
big
deal.
So
I
like
to
think
that
the
future
average
nft
like
doesn't
link
necessarily
to
a
jpeg
but
links
to
index.html.
A
That's
I
made
that
my
twitter
name,
because
I
thought
it
was
like
important
enough
and
when
they
link
to
index.html,
like
maybe
that
just
only
has
a
jpeg
in
it.
You
know
it's
like
a
browser
screen
with
the
image
you
bought
and
a
purple
background.
I
don't
know
so.
If
that's
your
default
case
for
an
nft,
then
index.html
could
be
part
of
a
whole
web
bundle.
It
could
pull
in
javascript.
A
It
could
pull
its
css,
it
can
be
a
browser-based
game
and
that
whole
experience
is
immutable
recorded
on
the
blockchain
owned
by
you.
You
can
share
the
url
with
other
people.
They
can
play
it.
You
can,
you
know
maybe
like
if
we
just
think
in
terms
of
what
nfts
offer.
Maybe
you
could
have
another
nft
that
you
want
to
combine
with
it
and
then
you
can
like
tell
that
javascript,
hey,
look!
A
Here's
I
just
signed
this
thing,
that's
signed
by
the
same
person
who
owns
you
that
says
import
this
object
in
and
then
it
can
go.
You
know,
use
an
api
call
to
fetch
that
object.
A
A
So
that's
how
you
would
do
it
in
the
nft
storage
stack
if
you
just
wanted
to
treat
nft
storage
like
as
dumb
as
you
could,
and
only
use
static,
fingerprints,
identifiers
on
your
nft
storage
links,
then
what
people
do
a
lot
and
you
could
use
it
for
this
again.
But
maybe
it's
like
a
you
know.
It's
kind
of
a
sledgehammer
when
you
might
want
like
a
ballpeen
hammer
is
the
smart
contract
often
has
a
way
to
replace
the
base
url.
A
A
And
so
you,
you
could
have
write
a
script
that
regenerates
all
500
of
them.
You
know
once
an
hour
creates
a
new
cid
calls
a
smart
contract
to
swap
out
the
base
url,
and
then
you
get
the
behavior
you're
looking
for,
I
think
we're
about
out
of
time.
So
I
guess
I
I'm
really
happy
with
the
questions
y'all
had
and
whatnot.
So
thanks.
