Interep aims to provide an identity solution for Ethereum users by bridging from an established digital identity source, typically a web2 platform. The product provides an identity layer in an application stack, and integrates with a privacy-focussed layer using the Semaphore framework. Interep can be used to to qualify users, or as an anti-sybil service.

A
A
So
brief
introduction
to
what
we
do,
it's
there's
lots
of
projects
in
the
trying
to
bring
identity
into
ethereum
and
they
tend
to
be
like
have
some
identity
source
and
and
build
it
up
from
from
the
ground.
Our
approach
is
a
pragmatic
approach
where
we
build
on
the
identity
that
we
already
have
in
our
digital
in
our
digital
lives,
and
we
bring
that
across
to
ethereum,
so
we
can
have
an
established
pool
of
or
established
identity
pool,
and
we
we
can
integrate
that
into
our
ethereum
applications.
A
So
yeah
very
much
a
pragmatic
approach
building
on
the
identity
sources
we
already
have.
So
what
we
aim
to
do
is
build
a
bridge
from
existing
digital
identity
sources
to
ethereum,
integrate
with
providers
of
those
identity
sources,
and
then
privacy
is
very
important
to
us.
So
we
build
on
the
semaphore
framework
and
integrate
with
with
that,
so
those
building
blocks
all
come
together
to
form
the
basis
of
an
application
so
identity.
A
So
we
spend
you
know
every
tweet
you
you
write
is
a
bit
of
humanity
that
goes
into
that
tweet.
That
represents
you
and
we
build
those
up
in
our
social
Social.
Network
accounts
people.
Some
people
spend
a
lot
of
time
on
that
kind
of
thing,
even
if
you're
not
into
social
social
networks.
Big
time
we
still
have
digital
identity
in
the
in
the
non-web
3
world.
We
have
things
like
government,
IDs
and
driver's
licenses
and
all
that
kind
of
stuff,
so
yeah,
it's
our
our
real
world.
A
Human
identity
is
reflected
in
those
digital
sources.
So
that's
what
we
try
and
build
on,
but
we
need
to
recognize
that
those
digital
sources
also
are
vulnerable
to
civil
attacks.
So
we
need
to
yeah
filter
out
the
Bots
and
kick
them
out
so
they're
the
kinds
of
things
we're
trying
to
do
with
interrep.
B
A
B
A
B
A
B
A
B
A
A
as
a
an
identity
source-
and
this
is
useful
in
some
cases-
not
in
others-
maybe
it's
not
so
useful
for
Gmail
accounts,
but
even
Gmail
has
some
barriers
to
entry.
So,
but
if
you've
got
like
a
DOT
edu
account
email
account,
then
that's
a
fairly
good
guarantee
that
there's
a
human
behind
that
account
and
and
a
reasonably
good
guarantee
of
uniqueness.
So
we
can
use
those
kinds
of
sources
and
integrate
with
those
government.
Authorities
are
good
in
that
you
know
the
government
make.
A
A
We
can
do
things
like
curating
groups
of
of
users,
so
that
might
rely
on
personal
knowledge
of
of
of
the
individuals
involved.
So
that's
that's
also
a
strong
way
to
guarantee
Humanity
other
ID
projects
we
can
integrate
with
those
and
we
can
integrate
with
Unchained
sources
like
use
things
like
nft
ownership.
That
kind
of
thing
now
a
bit
about
semaphore.
So
with
those
identity
sources
we
create
a
group.
We
put
someone
into
a
group
now
semaphore
relies
on
these
groups.
A
A
In
that
situation,
a
signal
is
a
vote
and
the
topic
is
a
proposal
and
semaphore
will
guarantee
that
that
anyone
who
votes
is
a
member
of
that
group
and
they
can
only
vote
once
and
all
of
that
is-
is
done
with
privacy.
So
you
don't
know
who
is
voting
on
a
particular
voting
in
a
particular
direction,
so
it
can
support
secret
votes,
but
it
still
maintains
strong
guarantees
of
membership
in
that
set.
B
B
A
A
We
have
some
criteria
that
we
apply
ourselves
with
Twitter
it's
a
a
fairly
High
bar
to
getting
gold
status.
You'd
need
7,
000
followers
with
2
000
followers
you'd
be
silver
with
less
than
that.
You'd
be
bronze,
but
we
also
linked
to
botometer,
and
that
will
do
an
assessment
of
your
Twitter
account
and
for
most
people,
that's
gonna.
That's
that's
going
to
give
us
a
score
on
how
much
botometer,
how
confident
they
are
that
you
are
not
a
bot.
A
So
most
people
with
a
bit
of
history
in
their
Twitter
account
and
a
few
followers
will
be
able
to
get
in
silver
or
gold.
Just
using
that
bottoma
to
school,
you
can
you
can
try,
you
can
join
a
group
in
and
on
our
website
and
assess
your
own
status
there
and
see
if
you
can
get
into
one
of
those
groups
I'll.
A
The
link
will
be
in
the
in
a
later
slide,
but
yeah.
So
the
way
we
do
it
is
is
we'll
we'll
do
that.
Evaluation,
give
someone
a
score
and
then
assign
them
to
that
to
that
that
level,
that
tier
bronze,
silver
or
gold
and
that
yeah
so
applications
will
be
able
to
choose
what
level
of
confidence
they
they
require.
A
So
the
nitty-gritty
process
of
of
joining
a
group,
the
user,
will
come
to
a
sign
on
screen.
Sometimes
it'll
be
a
step
just
before
they
go
in
to
use
the
application.
Sometimes
it
will.
It
can
be
done
well
beforehand.
Someone
can
join
a
group
and
then
they'll
keep
their
identity
and
use
that
to
kind
of
log
in
to
work
with
the
application.
A
Having
done
that,
the
our
application
will
do
that
assessment,
assign
the
user
to
a
tier,
called
Silver
bronze
and
then
invite
them
to
join
that
group.
So
the
user
will
do
their
Twitter
sign
on,
say:
okay,
you're
in
Twitter
gold.
Would
you
like
to
join
this
group?
They
click
click
that
button
and
then
the
next
step.
A
Is
they
link
that
with
an
ethereum
account,
so
the
user
will
sign
a
message
with
their
ethereum
account
which
guarantees
that
they
own
that
ethereum
account.
It
also
prevents
that
account
from
being
used
again,
so
they
can
only
join
once
and
the
Twitter
account
likewise
can
only
join
once
so.
Having
made
that
link,
we
we
have.
A
We
return
a
semaphore
ID.
The
semaphore
ID
provides
that
guarantee
that
that
Twitter
handle
is
represented
in
that
semaphore
ID
and
that
can
be
used
from
there
on
in
the
application,
without
revealing
that
link
of
who
the
actual
Twitter
user
is
behind
that
account,
and
neither
is
the
ethereum
account
revealed
in
the
actual
application
because
we're
using
semaphore
IDs,
and
it
conceals
that
we
can
also
work
with
on-chain
sources
of
proof
of
humanity
if
you
like.
A
Some
of
those
are
pretty
pretty
strong
guarantees
of
humanity
and
I'm
thinking
there
of
like
Sol
burn
tokens
or
poapps
like
the
pop-up,
you
get
from
your
Devcon
6
with
your
Devcon
6
ticket
that
can
only
be
owned
by
a
human
right,
because
they're
only
giving
out
tickets
for
humans.
So
that's
a
that's
a
pretty
good
indication
that
that
account
has
a
human
behind
it.
It's
certainly
very
hard
to
very
resistant
to
civil
attacks,
so
yeah.
A
I
talked
a
bit
about
this
before
yeah
membership
of
Dow,
for
instance,
and
we
can
guarantee
membership
guarantee
that
there's
a
human
behind
that
a
human
in
that
in
that
group,
but
never
reveal
who
that
human
is
social.
Networking
we
think,
is
a
promising
way
to
apply
this,
and
some
of
our
sister
projects
in
privacy
and
scaling
group
are
we're
working
on
this
you'll
hear
some
talks
in
Devcon
about
that,
but
yeah,
that's
another
place
where
privacy
is
important,
but
also
Humanity.
Proof
of
humanity
is
very
important.
A
A
A
B
A
Human
context
and
make
our
accounts
more
credibly,
human
and
our
applications
in
the
web3
world.
So
the
links
that
QR
code
is
to
our
Discord
you're
welcome
to
come
there
and
ask
questions
and
find
out
more
you're.
Also
welcome
to
come
and
hit
me
up.
I'll
be
hanging
around
a
lot
at
the
temporary
autonomous
Zone
down
on
the
ground
floor,
which
is
the
pse's
little
hub.
A
You're
welcome
to
visit
the
application
interrep.link
and
you
can
sign
on
there
get
just
get
yourself
signed
up
with
a
server
ID
see
what
your
Twitter
status
is.
Maybe
you
have
to
work
on
that
we've
got
documentation
links
we've
got
our
code
open
source
you'll
find
all
that
on
the
on
those
links,
but
yeah.
Please
come
to
the
Discord
and
ask
questions
if
you
or
come
and
ask
me
in
person.
A
So
thanks
for
all
that
the
QR
code
on
this
slide
is
the
Discord
for
privacy
and
scaling.
We
do
lots
of
cool
applications
in
the
xero
knowledge
space,
so
you
can
join
that
Discord
and
ask
questions
check
out
our
job
openings
if
you
like,
building
cool
applications
for
privacy
and
scaling
and
check
that
out,
and
on
that
note,
thank
you.
