Sign in with Ethereum is an almost accidental byproduct of #Web3, but is already turning into an incredibly powerful tool for user engagement and convenience. Wallet holders sign into DeFi protocols to manage their money or sales of NFTs but can it be much more than it already is. Linking seams of rich data to an ethereum address is the future of identity, ease and monetisation on the web.

A
Thanks
for
joining
welcome
to
signing
with
ethereum,
so
my
name
is
Lang,
I
am
an
investor
with
strot
crypto.
We
are
based
out
of
valet
a
crypto
native
VC
fund
to
focus
on
the
seed
stage,
I'm
joined
by
an
amazing
group
of
panelists.
Today.
Why
don't
we
do
a
quick
round
of
intros?
Let's
learn
how
what
you
guys
are
building
and
let's
kick
off.
B
So
yeah,
specifically
about
me,
I,
lead
developer
success
at
three
box
Labs.
Before
joining
the
team,
I
spent
most
of
my
career
in
data
science,
machine
learning
and
AI
applications,
basically
helping
open
source
companies
to
build
tools
that
enable
developers
to
build
Ai
and
machine
Learning
Systems
without
sacrificing
their
data
ownership.
So
super
excited
to
be
part
of
this
panel.
C
B
C
I'm
shave,
Malik
I
I'm,
the
CEO
and
co-founder
of
pool
I
used
to
be
an
investigative
journalist
for
the
guardian
for
about
half
a
decade,
so
a
weird
sort
of
intro
in
a
sense,
a
route
into
web
three
but
been
around
since
about
2017.
So
I
guess
I
do
I,
get
to
be
an
OG
now
Nick
I
think
so.
Yeah,
oh
wow,
okay,
so
I'll
tell
you
a
little
about
Paul.
What
we're
doing
is
we're
building
out
a
stack
for
date.
C
C
An
application
that
can
help
store
your
data
in
a
data
wallet
if
you
want
I,
think
sort
of
eoa
wallets
as
they
exist
at
the
moment.
Are
you
know,
sort
of
level
1.0
they're
a
bit
they're
a
bit
dumb
as
applications?
Can
we
make
them
more
intelligent
and
obviously
signing
in
with
ethereum
becomes
that
gateway
to
opening
out
that
information
sharing.
D
Hi
I'm
Nick
Johnson
founder
and
lead
developer
of
the
ethereum
name
service
ens,
which
helped
fund
sign
in
with
ethereum
and
started
the
whole
process
going.
So
ens
has
been
evolving
from
purely
a
name
lookup
service
into
a
your
decentralized
web3
profile.
So
we're
very,
very
interested
in
pushing
that
forward
with
things
like
sign
in
with
ethereum.
A
D
So
Simon
with
ethereum
status
and
if
it
between
ens
and
the
ethereum
foundation,
we
sort
of
identified
the
need
for
a
native
sign-in
protocol,
whether
there
were
dozens
of
different
implementations
of
signing
in
using
signing
a
message
with
your
wallet,
they
were
all
different
mini
head
security
issues,
many
had
usability
issues
and
we
sort
of
thought.
You
know
this
would
be
an
awful
lot
better
if
it
was
consistent
and
and
identical
across
all
systems
wallets
would
be
able
to
build
and
support
for
it
with
better
ux
for
users.
D
Sites
would
be
able
to
use
reusable
components,
and
so
we
got
together
with
the
ethereum
foundation
to
to
get
that
going.
We
put
out
an
RFP
got
a
number
of
submissions
and
Spruce
were
the
ones
who
won
the
RFP
and
they've
done
an
outstanding
job.
The
building
was
standard
and
and
getting
it
out.
There
perfect.
C
Well,
actually,
it
was
going
to
come
at
a
slightly
different
angle,
which
is
from
the
in
fact
the
exact
opposite
end
the
ux
side
of
things,
and
it's
worth
remembering.
Obviously
we,
you
know,
a
lot
of
people
here
have
signed
in
with
Google
signed
in
with
Facebook
I.
Don't
think
it's
kind
of
a
pleasurable
experience,
because
you're
sort
of
wary
of
the
fact
that
yeah,
you
know
someone
else
is
a
centralized
party
in
all
of
this
someone
you
might
not
appreciate,
but
yeah.
It's
so
convenient
right.
C
It's
so
much
more
convenient
than
signing
in
with
your
email
and
then
trying
to
remember
that
damn
password
for
that
specific
application
and
if
obviously,
you
want
to
have
any
sort
of
security
over
passwords,
it's
it's
you're
then
left
with
like
15
20
50
passwords
right,
and
that
becomes
a
problem,
massive
problem
in
and
of
itself.
So
I
remember
this
moment
when
I
could
sign
in
with
ethereum
with
uni
swap
I
think
that
was
my
first
time
when
I
really
appreciated
what
was
going
on
and
I
was
like
my
God.
C
This
is
exactly
what
I've
always
wanted
right.
It's
this
really
happy
moment
where
you're
like
it's
my
wallet
and
someone
else
is,
is
recognizing
my
wallet
address
and
somehow
now
I've
kind
of
been
on
boarded
in
this
decentralized
fashion,
and
it's
brilliant.
It's
just
brilliant,
and
it
was
just
like
that
and
I
just
thought
God.
This
is
definitely
the
future
and
this
is
really
in
a
sense,
underrated
protocol.
Where
can
it
go
next?.
A
In
terms
of
maybe
interoperability
and
multi-chain
and
kind
of
carrying
that
you
know,
ens,
Name,
Across,
multiple
domains
and,
and
you
know,
wrapping
your
identity
and
kind
of
self
sovereignty
with
that,
could
you
talk
to
maybe
what
are
the
possibilities
here
in
terms
of
use
cases,
and
just
you
know
what
are
we
building
towards
right
now?
Let's
start
with
that,
just
you
know.
B
So
if
we
are
building
this
layer
right
now,
we
really
have
to
think
about
how
that
relates
to
decentralized
identity,
security,
and
things
like
that
and
sign
in
with
ethereum
has
a
lot
of
advantages
in
that
area.
I
think
we'll
cover
that
a
little
bit
more
as
well,
but
we
do
see
a
lot
of
interest
and
use
cases
from
verifiable
credentials
and
and
reputation
side
of
things,
for
example,
git
coin
they
just
quite
recently
released
GetGo
and
password
and
they're.
B
The
way
it
handles
this
generation
and
identity
overall,
it
can
be
paired
with
additional
tools
that
enable
session
management
and
I
believe
that
that
opens
so
many
opportunities
for
a
bit
more
mature
and
more
interactive
applications
to
be
to
be
built
out
there.
So
I
really
hope
that
we
will
see
some
really
interesting
use
cases
in
web3
gaming,
also
webview
social,
that
require
a
little
bit
more
user
interaction
and
we
sign
in
with
ethereum
you
don't
really
have
to
and
session
management.
B
You
don't
have
to
approve
every
single
action
that
you
run
on,
while
interacting
with
the
application.
So
I
think
that
will
be
super
interesting
to
see,
and
another
thing
that
is
really
nice
to
see
as
well
is
that
we
see
some
web
to
Native
applications
adopting
a
sign
in
with
ethereum
as
well,
for
example,
discourse
forums.
They
are
already
have
a
plugin
that
users
can
use
basically
to
sign
in
with
their
ethereum
wallet,
which
is
great
and
I.
B
C
Oh
I
mean
so
many
things,
the
picking
up
on
that
point
about
session
management.
It's
so
important
when
you
know
it's
worth
going
back,
maybe
in
history
to
kind
of
Netscape
and
then
creating
the
cookie
right
in
order
to
get
some
kind
of
user
convenience
in
regards
to
session
management,
and,
if
you
think
about
it,
cookies
have
been
I
mean
they've,
just
been
terrible
there
as
a
piece
of
technology.
They
are,
they
are
awful,
they
don't
actually
really
do
the
job.
C
Then
they've
also
been
employed
to
do,
which
is
basically
kind
of
spying
by
proxy.
And,
of
course,
now
third-party
cookies
are
being
shut
down
by
Chrome
in
you
know,
will
they
be
delayed?
It
twice
now
so
web
2's
got
this
problem
too,
and
in
fact,
just
generally
speaking,
you
know
in
terms
of
the
the
internet
at
large,
not
just
web3.
We've
had
this
issue
of
you
know
what
is
my
identity
on
the
internet?
Is
it
my
email?
C
Is
it
my
mobile
number,
like
you
know,
or
is
it
some
centralized
identity
via
Google
and
Facebook
and
I
think
this
is
really
the
perfect
solution
which
is
via
sign
in
with
ethereum
here's.
My
wallet
address
right.
It's
something
I
own,
it's
something
I
port
with
me
and
it
actually
works
on
both
sides
of
that
relationship,
because
obviously
Publishers
websites
want
to
know.
Well,
who
are
you
who
are
you?
C
Are
you
the
same
person
that
showed
up
before,
in
which
case,
at
least
in
the
very
least,
this
is
going
to
make
this
convenient
for
you,
because
we
can
pull
up
all
that
session
management
stuff
from
before
right.
Here?
Are
your
preferences,
great,
so
I
I
think
it's
just
there's
just
so
much
opportunity
as
well
with
cookies,
disappearing
right.
This
is
the
replacement
in
that
sense
for
that
identity,
aspect
of
cookies
and
session
management.
It's
very
exciting.
D
Guess
it's
worth
drilling
down
a
little
bit
on
why
we
need
something
like
cyan
was
ethereum
in
the
first
place,
because
you
know
ethereum,
serverless
apps.
You
know
your
typical
smart
contract
interaction.
You
don't
need
to
authenticate
yourself
to
the
app
because
you're
authenticating
yourself
with
the
transactions
you
make.
D
I
guess
talking
about
the
cross
chain
thing
too.
You
know
the
the
ens
as
well
suited
to
the
integration
here
and
obviously
I'm
going
to
show
UNS,
but
because
ens
supports
multi-chain
identities
and
so
forth.
So
you
can
authenticate
using
Signum
as
ethereum
and
you
import
your
profile,
which
has
addresses
for
whatever
chain
you're
using
or
none
at
all.
So.
A
B
B
They
in
general
I
think
still
need
a
little
bit
more
conviction
that
these
kind
of
Protocols
are
reliable
and
scalable
and
and
safe,
especially
I'm,
just
thinking
what
would
it
take
for
a
big,
let's
say,
Healthcare
company
or
in
insurance
company,
to
adopt
something
like
that
to
allow
users
to
log
into
their
systems,
and
there
are
a
few
things,
yeah
I
think
they
still
need
a
little
bit
more
conviction
that
these
systems
are
secure,
reliable
and
also
I.
Think
that
is
still
an
unsolved
problem
of
users
managing
their
keys.
B
So
we
obviously
shift
so
much
responsibility
to
the
user
and
then
not
not
to
do
some
silly
things
with
their
private
keys.
So
having
good
Solutions
there
and
and
having
reliable
experience
for
both.
Let's
say
companies
and
the
users
is
important
and
yeah
overall.
That
also
boils
down
to,
in
general,
I
think
education
for
people
to
understand.
B
This
is
super
important
and,
as
she
mentioned,
that's
one
of
the
biggest
advantages
that
that
to
single
sign-on
methods.
Have
it's
so
simple,
so
easy
you
just
click
a
few
buttons
and
you're
in
and
it's
great,
so
we
have
to
make
sure
that
for
web
3
Solutions
we
strive
for
at
least
similar
experience
or
even
better
so
I
think.
Overall,
the
standardized
message
that
sign
in
with
theorem
produces
it's
already
a
really
great
step
towards
that
direction.
It's
easy
to
understand
for
the
user.
B
C
C
Just
taking
today
for
me,
I,
signed
in
to
Ave
in
a
sense
and
I
was
able
to
to
realize
that
my
health
Factor
was
was
really
low
and
I
might
need
to
borrow
some
money
to
prop
up
my
Margin
Call
and
then
the
second
thing
I
did
was
to
sign
into
the
the
app
for
this
conference,
which
was
great
and
obviously
now
it
remembers
and
I'm
able
to
personalize
that
experience
right.
That's
sort
of
brilliant
and
I.
C
Do
you
know
various
things
like
that
on
a
regular
basis,
but
where
this
goes,
I
mean
Justina
mentioned
Key
Management,
it's,
it
was
listening
to
a
podcast
and
I
think
they
were
there's
still
eight
addresses
which
have
never
pulled
out
their
ethereum
from
the
original
crowd
sale
and
that's
because
they
lost
their
keys.
So
if
ethereum
devs
right
back
in
whenever
it
was
2015
can't
manage
their
keys,
how
do
we
like
expect
Ordinary
People
to
do
it?
C
So
that's
a
huge
problem
but
I
think
I'd
like
to
see
the
stage
where
you
know
people
are
signing
into.
Let's
say
the
Wall
Street,
Journal
and
and
they're
able
to
make
micropayments
right
because
they're
on
an
L2
for
paying
for
an
article
and
I
want
that
to
be
on
that
list
of
options
right
sign
in
with
Google
Facebook
and
seaweed
right
sign
in
with
ethereum
I.
Just
want
it
to
be
there
that
that's
I,
think
and
in
a
sense,
I.
C
D
You
know
metamask
rainbow
everyone
else
to
identify
sign
in
with
Theory
messages
and
show
a
nice
user-friendly
dialogue.
That
says
you
know
this
is
what
you
need
to
know.
We've
checked
it's
a
real
message.
You
know
here's
what
you're
signing
in
with
here's,
what
permissions
you're
giving
them
same
as
you
would
see,
with
like
an
oauth
dialogue
for
GitHub
or
Google
or
whatnot
and
I.
Think
that
will
that's
a
big
step
forward
from
the
text-based.
You
know
sign
this
message
window
right.
A
I
wanted
to
touch
point
on
the
institutional
partnership
side.
I
mean
the
short
term
medium
term.
Is
there
a
way
that
you
know
we
work
together
with
a
lot
of
the
large?
You
know,
tech
companies
or
you
know
fintech
tradify,
or
is
this
more
kind
of
our
siled?
You
know
Bottoms
Up
kind
of
way
of
of
starting
a
new
movement
here,
so
it
was
just.
You
know.
B
Yeah
no
I
I
I
really
hope
that
it's
not
gonna
be
siled
and
that
we
can
collaborate
with
them
and
yeah
I
really
do
think.
It's
really
about
understanding
the
challenges
like
again,
as
I
mentioned
about
like,
for
example,
even
Healthcare,
which
I
think
would
be
massive
thing
to
potentially
about
these
kind
of
methods.
B
We
would
be
dealing
with
extremely
sensitive
data,
so
these
kind
of
Institutions
they
have
another
set
of
challenges
that
they
have
to
solve.
Also,
we
have
data
regulations
that
we
have
to
take
into
account
and
like
what
does
it
mean,
then
that
users
use
their
let's
say
with
three
wallets
and
then
these
kind
of
protocols,
and
so
on
so
yeah
I
hope
that
we
can
collaborate
on
understanding
what
kind
of
issues
we
have
to
address
and
find
Solutions
on
that
end
and
Implement
them
and
yeah
I.
C
Actually
we're
working
with
ceramic,
so
our
vision
is
so.
The
wallet
is
just
in
a
sense.
The
application
right,
the
private
key
and
the
mechanism
for
signing
are
the
protocol,
and
that's
really
where
the
I
think
the
power
lies.
How
good
can
you
make
the
application,
though
so,
as
I
said
at
the
moment,
I
think
wallets
are
actually
going
to
be
crude,
but
just
they're
pretty
dumb
at
the
moment:
smart
contract?
C
Well,
let's
take
you
a
step
up
right
because
then
you
kind
of
yes,
you
can
get
subscriptions
and
things
like
direct
debits,
right,
more
kind
of
refined
modes
of
payment,
not
just
single
transactions,
but
now
imagine-
and
this
is
why
we're
working
with
ceramic
being
able
to
put
data
into
effectively
a
storage
Vault
if
you
want,
where
you're
also
using
the
same
private
key
as
you
would
for
your
wallet
to
permission,
reads
for
that
Vault!
So
now
you're
entering
a
world
in
which
you've
basically
got
a
big
digital
backpack.
C
C
I
do
want
to
be
tracked,
but
of
course
they're
managing
all
of
those
permissions
and
it's
not
interoperable
right
and
they've
kind
of
locking
out
everyone
else
right,
centralized.
The
question
is,
then,
how
do
you
fill
up
those
data,
vaults
and-
and
that's
the
question
question
that
we've
been
working
on
at
pool
with
a
lot
of
other
data
unions?
C
You
know:
how
do
you
structure
the
that
data,
because
you
can't
just
expect
people
to
dump
stuff
into
there
and
then,
of
course,
that
becomes
an
even
more
valuable
propositions
for
huge
Enterprises
out
there
who
go?
Oh
right
now
you're
turning
now
you're
creating
humans
who,
we
think
are
verified
they're.
Turning
up
with
data,
we
can
tell
a
story
from
them
right.
We
they
can
also
pay
from
the
same
application,
we're
jumping
into
web3
right.
It's
not
just
this
is
crypto.
We
could
make
some
money
off
some
speculation
or
nfts.
That's
nice.
D
Yeah
I
think
you
know
you
asked
originally
about
like
do
we
you
know.
Is
this
a
silo
thing?
Is
this?
You
know
just
us
and
I
think
we
only
really
succeed.
If
it's
not
you
know,
Ian
s's
vision
is,
is
a
web
3
identity
for
the
for
everything
and
I
think
that
works
best
and
and
sign
in
with
therm
workspace?
D
If
it's
everywhere,
you
know,
ideally
the
ux
improves
and
the
the
number
of
users
using
web
3
wallets
improves
to
the
point
where
this
is
people's
preferential
sign-in
compared
to
Google
or
Twitter
or
whatnot,
because
it's
actually,
you
have
control
of
your
data.
You
have
control
of
your
identity,
you're,
not
relying
on
a
third-party
identity
provider
to
to
do
it
for
you
and
to
decide
that
you're
allowed
to
continue
to
have
an
identity
makes
sense.
A
So
I
wanted
to
touch
on
that
the
Privacy
piece
a
little
bit.
You
mentioned
a
little
bit
about
that.
You
know
we
have
a
lot
of
sensitive
data,
a
lot
of
kind
of
identity
and
credentials
to
to
think
through
here
as
well,
especially
with
use
cases
in
you
know,
supply
chain
in
hospitals.
Things
like
that.
Could
you
talk
through?
Maybe
some
of
the
techniques
we're
using
currently,
including
maybe
zero
knowledge,
proofs
and
other
techniques
that
you
know.
How
are
we
working
towards
that
right
now,.
B
B
We
really
have
to
think
about
how
we
can
pair
that,
with
other
options
like
zero
knowledge
proof,
where
users
don't
really
have
to
prove
that
they
like
who
they
really
are,
but
we
can
only
use,
for
example,
their
address
or
or
details
that
are
stored
in
in
their
decentralized
identifier,
so
I
think.
Overall,
the
advantage
of
signing
with
ethereum
is
that
every
single
user
that
owns
a
wallet
they
have
a
did,
which
then
can
be
used
to
build
out
these
kind
of
systems.
D
C
Just
briefly
for
me,
then
I
would
say:
look
if
you're
going
to
carry
a
data
wallet
around,
let's
say
the
middle
of
us.
Then
you
know
you
can
start
to
see
how
zero
knowledge
proofs
protect
users
privacy.
So
for
one
show
example,
if
you
let's
say
you've,
managed
to
Port
all
of
your
financial
transaction
data,
but
actually
most
people
on
the
other
side
just
want
to
know
how
much
you
earn
in
a
year.
They
don't
want
to
know
every
single
transaction
you've
made,
and
actually
they
don't
want
to
even
keep
that
data
anymore.
C
It's
just
so
much
of
a
hassle
from
a
gdpr
perspective
or
CCPA.
So
zero
knowledge
proof
simply
says,
look
I.
You
know
what
is
that
number
at
the
end
of
the
day
right?
Is
it
70k?
Is
it
20K
whatever
it
is
right?
I
just
want
to
know,
and
that's
that's
it.
That's
one.
Application
I
think
we're
starting
I,
know
vitalik's
very
enthusiastic
about
so
knowledge
proofs
in
their
applications,
but
it
was
still
at
the
beginnings
of
this
I
think
we're
still
building
out
actually
the
raw
layer
for
a
data
wallet
in
this
thing.
A
C
So
if
you
want
the
non-plitcher
goes,
first
party
data
is
data
that
a
website
has
about
you
right,
it's
their
data.
You
turn
up
at
their
website.
They
know
who
you
are,
and
you
know
they
have
a
again.
You
know
an
identification
about
you
and
then
they're
like
oh
look.
They
spent
this
much
time
on
a
website.
This
is
what
they
read.
This
is
what
they
did
et
cetera.
Etc
third-party
data
is
basically
people
spying
on
you.
C
No
one
is
proud
of
what's
been
created,
but
it's
a
huge
ecosystem,
but
it's
a
it's
been
closed
down,
literally
as
we
speak.
So,
for
example,
you
know
if
you
anyone
with
an
iPhone
will
have
seen
the
update
is
14.5
where
they
said.
Do
you
want
this
app
to
track
you
and
I'm,
pretty
certain
that
I
mean?
Can
I
ask
the
audience
like
who
said
yes
to
that?
Who
said
yes
to
being
tracked?
Okay,
literally
no
one,
one.
C
It
out
of
this
conference,
so
you
know
that
turned
out
that
cost
Facebook,
for
example,
10
billion
dollars,
because
they've
been
locked
out
by
Apple
and
apple,
is
like
rubbing
their
hands
with
Glee
going.
Privacy
is
great,
because
now
we
can
increase
our
advertising
revenue
from
5
billion
to
30
billion.
So
it's
just
a
big
play
right,
but
that's
what
they're
using
so
that's
a
state
of
third
party
zero
party.
C
It
says
this,
which
is
why
don't
we
just
work
in
conjunction
with
people
who
actually
want
to
share
and
be
pragmatic
about
sharing
and
monetizing
their
information.
So,
as
I
said,
there
were
about
120
data
unions,
probably
about
30.
To
40
of
them
are
a
position
where
they're
they're
monetizing
their
data.
Now
so
they've
got
I
mean
I'll.
Give
you
one
example
like
sweatcoin
is
kind
of
interesting
they're
actually
doing
it
in
inverse
and
they're
about
to
start
monetizing
their
data
of
their
users.
C
They've
got
120
million
downloads,
25
million
sort
of
active
users.
Pogo
is
another
really
great
example:
they're
in
the
web,
most
of
them
Traverse
web
2
and
web
three
I
know
Lyndon.
One
of
the
founders
of
ozone
is
around,
you
know
so:
they're
collecting
all
sorts
of
data,
Wellness
data
click
stream
data
and
and
actually
that
whole
Space
is
about
to
open
up
massively
in
2024
March
2024
put
it
in
your
diary.
C
The
EU
is
about
to
give
real-time
portability
rights
to
everyone.
That's
450
million
people
in
Europe,
so
you
can
Port
your
Google
Facebook
Amazon
Apple
data
and
more
and
LinkedIn,
because
it's
Microsoft
and
that's
just
about
to
explode
that
ecosystem.
So
people
can
now
say
this.
Is
my
data
I'm
porting
it
to
a
data
Union
that
data
Union
is
going
to
be
a
fiduciary?
For
me,
this
is
zero
party
data.
Now
it's
coming
direct
from
Source,
let's
monetize
it
yeah.
B
Yeah
yeah,
of
course,
yeah.
So
as
I
mentioned
ceramic
is
a
decentralized
Data
Network
and
we
really
try
to
build
out
the
infrastructure
that
developers
can
use
to
store,
manage
user
data.
So
just
like
should
mentioned
it's
like
becomes
your
data
backpack,
so
I
think
this
is
probably
where
I
would
definitely
put
ceramic.
B
We
definitely
spend
a
lot
of
time
thinking
about
how
we
can
build
it
in
a
secure
way,
so
that
a
user
is
the
owner
and
has
the
ownership
of
their
data.
They
can
manage
it.
So
the
centralized
identifiers
are
at
the
core
of
how
ceramic
works
and
then,
when
users
interact
with
applications
that
are
built
on
ceramic
then
did
is
really
the
linking
point
that
connects
a
user
to
the
data
streams
that
they
have
generating
while
interacting
with
the
applications.
B
Right
now
we
are
making
some
quite
exciting
updates
to
ceramic,
so
I
will
just
quickly
mention.
We
just
released
a
developer
preview
of
compose
DB,
so
we
are
expanding
the
capabilities
of
what
ceramic
offers
in
terms
of
building
applications
in
an
easier
way.
So
now
users
can
developers
can
Define
their
application
schemas
using
graphql.
That
also
opens
more
opportunities
to
actually
interact
with
their
data
by
curing
the
data
using
graphql
apis.
B
B
So
what
that
means
for
a
developer
like
if
you
build
on
ceramic
and
you
build
a
data
model,
so
basically
Define
the
scheme
of
the
model.
You
can
share
the
model
on
what
we
call
model
Discovery
so
that
other
developers
that
are
potentially
building
similar
application
or
something
that
they
just
simply
need
a
specific
feature
or
the
model
that
already
exists.
They
don't
have
to
build
it
from
scratch.
B
They
can
take
something
that
exists
on
a
Model
Discovery
platform
and
and
use
it
for
their
application,
or
if
they
need
some
additional
functionality
there,
they
can
update
the
models
and
then
also
share
with
the
community.
So
we
really
try
to
make
more
that
development,
more
Community
Driven
and
allow
developers
to
help
each
other
to
build
faster
and
and
better
applications
and
yeah,
also
data
interoperability,
as
well
as
something
that
we
really
take
seriously
and
make
sure
that
data.
B
C
Stuff
I
was
going
to
say:
if
people
don't
know
the
secret
source
of
ceramic
really
is
certainly
from
our
perspective
is
that
you
can
deal
in
real-time
data,
so
you,
like
ipfs,
is
great
for
static
stuff
right,
one
off
like
I'm,
going
to
store
this
that's
great.
If
you
want
a
persistent
stream,
then
you've
got
a
different
problem
right,
because
you're
gonna
have
to
kind
of
rewrite
and
rewrite
and
rewrite,
and
that's
going
to
cost
a
lot
and
it's
horribly
inefficient.
A
Let's,
let's
talk
about
on
the
consumer
end
with
monetization
of
data
and
after
sign
in
and
you
know,
kind
of
that
whole
user
experience
from
end
to
end.
What's
like
the
I
guess
the
Grand
Ridge
I
know
you
guys
talked
about
this
a
little
bit,
but
you
know
with
VNS,
let's
say
and
cross
chain
and
monetization
with
Brands.
Let's
say
you
know:
how
do
you
think
about
that
kind
of
like
blue
blue
sky
vision,.
D
D
So
we
sort
of
it's
more
a
platform
that
people
can
build
monetizable
ideas
on
than
something
monetizable
in
and
of
itself,
I
think
when
it
comes
with
signing
to
sign
in
with
ethereum
it
you
know,
provides
access
to
all
these
platforms
as
well,
but
it
hasn't
been
our
core
focused.
Historically,
look.
C
C
D
I
think
like
it
was
built
with
extensibility
in
mind
reasonably
well.
You
know
the
the
format
of
the
message
you
sign
allows
optional.
Fields
allows
apps
to
specify
individual
things.
Wallets
can
then
support
those
as
time
goes
on
so
I'm
hopeful
that
the
way
it
will
be
updated
is
by
publishing
additional
speaks
that
add
functionality
through
those
mechanisms
we
already
have,
rather
than
needing
changes
to
the
base
protocol,
at
least
if
we
did
our
job
that
will
be.
You
know,
the
gold
is
always
the
possibility
of
ce2,
but
maintaining
backward
compatibility.
D
I
think
is
really
important,
because
in
some
sense,
whenever
you
don't,
you
start
from
scratch.
You
know
quite
as
hard
as
the
first
time,
but
you
spend
an
awful
lot
of
effort
just
getting
back
to
where
you
were
in
terms
of
adoption
and
so
on.
You
know
whenever
you
release
something
new,
that
everyone
has
to
support
so.
A
C
Yeah
this
is
so
sobound
tokens
is
obviously,
you
know,
is
put
forward
by
vitalik
and
Glenn
Weil
and
one
other
author,
Priyanka
I,
think
it's
Priyanka
I
forget
her
name.
This
is
really
terrible.
It's
always
the
third
person
who
drops
off
that
list
in
terms
of
you
remembering
and
I,
don't
know,
I
I,
don't
know
if
it's
a
very
so
the
idea
is
basically,
you
have
tokens
that
are
inherently
bound
Soul
bound
to
someone's
address
right,
so
they
in
a
sense
in
essence,
can't
really
be
transferred,
become
meaningless.
C
After
that,
I
don't
know
Nick
if
you
want
to
kind
of
elaborate
more
on
a
technical
perspective
and-
and
that
is
in
essence,
wrapped
up
with
your
identities
and
I.
Think
from
like,
if
you
take
a
kind
of
you
know
a
much
higher
perspective,
just
sort
of
step
out,
it's
good
at
recording
moments.
In
a
sense,
it's
not
too
different
from
poapps.
C
If
people
know
the
value
of
that,
where
you're
like
taking
a
from
a
from
a
storytelling
perspective,
you're,
like
you're,
capturing
a
photo
and
you're
like
here's
this
moment,
it's
perfectly
captured
great
and
it
says
something
about
you
at
that
moment
what
it
isn't
really
doing.
It's
sort
of
leaving
a
trail
of
breadcrumbs
for
other
people
to
then
put
together
a
story,
and-
and
in
this
end
it's
not
too
different
from
I
mean
it's
got
other
applications,
but
this
is
from
a
kind
of
data
perspective
or
from
an
identity
perspective.
D
You
know
all
of
us
here
probably
have
multiple
wallets,
probably
most
or
all
of
us
here
have
the
experience
of
moving
from
one
main
wallet
to
another,
and
if
you
have
a
truly
like
non-transferable
token,
then
you
leave
your
identity
behind
when
you
do
that
and
from
a
security
point
of
view.
The
last
thing
we
want
to
do
is
discourage
people
from
making
advisable,
updates
and
moving
to
more
secure,
wallets
and
and
key
storage
and
stuff.
D
But
I
think
the
more
sophisticated
view
of
the
sold
down
token
is
that
it
is
effectively
non-separable.
So
if
you
have
one
that
represents,
you
know
your
your
national
identity
and
one
that
represents
your
membership
of
an
association
and
so
forth.
You
can't
transfer
one
to
one
place
and
another
to
another
place.
You
can
move,
but
you
have
to
move
as
a
whole.
D
You
know
you
can't
split
your
identity
into
pieces
and
a
different
approach
to
that
which
I'm
quite
fond
of
is
that
his
stations,
and
particularly
if
you
tie
them
to
an
identity
such
as
an
ens
name,
because
you
can
transfer
the
ens
name
to
a
new
account
and
all
of
your
attestations
come
with
you
because
they're
pointing
at
you
know
that
this
name
is
over
18.
This
name
is
a
citizen
of
New,
Zealand
and
so
on
and
so
forth,
and
the
attestations
are
cheaper
too,
because
you
don't
need
to
put
them
on
chain.
C
Yes,
you
know
these
things
are
sort
of
fluid,
and
but
we
can
tell
a
kind
of
more
interesting
story
and
obviously
people
yeah
do
want
to
shift
people's
identities
inherently.
Do
change
we're,
not
static
beings?
In
that
sense
and
I
guess
you
know
it's
a
good
I
felt
like
the
whole,
the
the
Soul
band
tokens
are
incredibly
good
theoretical
exercise,
but
from
a
ux
perspective,
just
like
the
worst
in
a
sense
to
implement,
because
humans
are
complicated.
In
that
sense,
right.
A
B
Entire
hour
to
talk
about
that,
like
overall
I'll
try
to
make
this
quick
and
short
I,
think
most
of
people
here
are
familiar
with
problems
with
AI
and
and
driving
insights
from
data
in
in
web
2,
I'm
speaking
about
users
giving
up
their
data
ownership.
These
big
companies
that
have
algorithms
that
are
being
trained
on
their
data
do
most
of
their
work
in
a
closed
source.
So
there
is
no
way
to
really
tell
what
is
happening
behind
that
and
then
again
like.
B
If
you
use
traditional
sign-in
methods,
you
give
out
like
entire
network
of
your
interactions
with
different
applications,
then,
on
the
other
side,
there
is
another
challenge
for
developers
specifically
in
web
2
that
I've
seen
so
many
times
like.
If
you
are
a
smaller
company,
and
you
don't
have
massive
user
base
like,
for
example,
Google
or
or
Facebook,
you
have
two
main
problems,
one
of
them.
You
might
not
have
a
big
enough
team
to
build
out
these
Advanced
systems,
and
another
problem
is
that
most
of
the
data
is
extremely
siled.
B
So
if
you
don't
have
access
to
these
massive
data
pools,
you
are
quite
Limited
in
terms
of
how
good
those
ml
or
AI
systems
can
be,
but
at
the
same
time,
let's
be
honest,
these
algorithms,
that
we
interact
with
on
a
daily
basis
like,
for
example,
YouTube
recommendation
algorithm.
That
gives
you
suggestions
for
the
next
video
to
watch.
B
Obviously
you
need
data,
but
what
I'm
really
hopeful
with
signing
with
ethereum
about
again
I
mentioned
that
session
management,
which
should
open
up
the
doors
for
more
feature-rich
applications.
Again
I
mentioned
gaming
applications
web
3,
social
and
that
should
allow
more
web
3
apps
to
potentially
have
some
kind
of
sprinkle
of
machine
learning
systems
that
improve
user
experience
and
then,
at
the
same
time
there
is
a
massive
interest
right
now
in
decentralized
finance,
decentralized,
machine
learning
as
well,
and
there
are
some
methods
there
already.
B
That
should
allow
users
to
interact
with
these
machine
learning
systems
based
built
on
a
blockchain
without
giving
out
their
data
and
instead,
for
example,
sharing
the
weights
of
the
model
that
is
being
trained.
I
will
not
go
too
much
detail
into
technical
details
there,
but
basically
I
think
that
our
opportunities
there
to
hopefully
get
to
at
least
similar
user
experience
in
web3
as
well
compared
to
web
2
or
maybe
even
better.
But
there
is
still
a
lot
of
work
that
needs
to
be
done
to
enable
developers
to
build
these
quite
Advanced
and
feature-rich.
A
C
B
C
A
E
C
C
So
the
rules
that
are
now
coming
out
in
March
2024
were
kind
of
a
result
of
that
lots
of
other
people.
Actually
even
a
few
people
from
web3
were
involved
in
those
discussions.
So
that's
now
resulted
in
real-time
data
portability
being
a
right.
So
at
the
moment
it's
just
portability
rather
than
retail
real-time
portability,
so
people
can
now,
instead
of
sending
an
email
saying,
I
want
to
get
all
my
data
and
then
it
comes
back
30
days
later
in
a
Json
file.
It's
like
sign
in
to
a
third
party
use,
OA
or
oauth.
C
In
a
sense,
you
in
fact
use
their
tools
against
them.
It's
great
and
then
you'll
be
able
to
Port
your
data
to
a
third
party
to
whomever
you
nominate,
and
so
that's
at
least
what's
come
as
a
result
of
that
which
is
bloody,
fantastic.
It
means
the
silos
for
Google
and
Facebook
are
about
to
be
in
a
sense
ripped
down
we're
about
to
witness
a
you
know,
a
vast
experiment,
certainly
in
Europe,
and
then
they
can't
imagine
like
Americans
standing
by
going,
oh
yeah.
C
B
Yeah,
no,
that's
a
great
question.
I.
Think
overall,
like
we
didn't
speak
too
much
about
like
technical
details
of
signing
with
ethereum,
but
I
think
it
does
make
it
easier
to
follow
certain
legislations
and
think
about
like
what
will
be
happening
with
user
data
because
again,
like
user
becomes
the
owner
of
their
decentralized
identifier,
which
then,
when
linked
with
let's
say,
data
storage
systems,
still
allows
them
to
manage
their
data
in
a
way
and
it's
not
being
shared
with
like
anyone
online.
B
So
I
think
these
kind
of
methods
that
we
have
being
implemented
should
make
it
easier
and
the
same
apply
so,
for
example,
and
if
these
are
quite
often
also
used
for
as
decentralized
identifiers.
But
the
problem
is
that
they
are
public.
They
are
on
chain.
So
with
options
like
sign
in
with
ethereum,
we
can
now
leverage
more
of
off-chain
applications
as
well
for
data
storage
and
so
on.
So
that
makes
it
I
think
in
general,
easier
to
be
compliant
with
registrations
and
and
rules
out
there.
A
D
I
guess
you
know,
things
like
GDP
are
all
about
how
companies
that
have
your
data
can
share
it
with
third
parties,
and
things
like
sign
in
with
ethereum
and
decentralized
profiles,
give
you
that
control
so
in
a
way
they
obsolete
it
and
they
they're
very
good
way
to
be
compliant
with
it.
Like
the
zero
party
data,
you
were
talking
about
Chev.
G
Cool
two
questions:
first,
one
for
people
who
want
to
contribute
to
sign
in
with
ethereum
what
is
a
good
Hub
to
like
reach
out
and
help
build.
It
and
second
question
is
the
word
ethereum
a
limiting
factor
for
adoption
and
maybe
like
sign
in
with
a
private
key
or
self-sovereign
identity.
A
more
appealing
button
to
add
next
to
sign
in
with
Google
or
something.
D
C
Think
we
should
be
like
super
proud
of
that
right
like
and
we
can
call
it
seaweed
and
we
haven't
been
calling
it
CB
on
stage.
Maybe
we
should
have
done
that
a
bit
more,
but
no
I'm,
like
you
know,
I,
want
to
know
from
websites
as
soon
as
I
had
that
uni
swap
experience
and
the
RV
experience
I
was
like.
Why
isn't
every
other
website
like
that,
like
I,
want
to
know
like
and
prod
them
and
go?
Why?
Why
can't
I
just
sign
in
with
my
wallet
I?
