Description
By integrating Chainlink into the Filecoin ecosystem, a multitude of bidirectional smart contract capabilities emerge that were previously impossible to achieve. Join Chainlink's Sergey Nazarov and Filecoin's Juan Benet for a discussion of those new capabilities and how they advance the move to Web3.
A
Welcome
everyone,
I'm
super
excited
to
be
speaking
with
sergey
today
sergey
and
I
go
way
back
for
many
years.
We
we're
both
starting
our
respective
projects
and
have
been
collaborating
for,
throughout
this
whole
time,
building
different
pieces
of
of
the
tech
stack
and
and
watching
so
many
amazing
teams
build
upon
our
tech
together.
A
B
You
can
imagine
that
an
oracle
network
doesn't
in
some
in
some
way
and
what
that
does
is
it
provides
a
critical
set
of
services
that
then
get
consumed
in
the
smart
contract
code
to
expand
the
universe
of
what's
possible.
The
first
use
case
of
oracle
networks,
which
we
essentially
pioneered,
which
is
kind
of
why
we
have
this
position
in
in
terms
of
adoption,
is
on
around
data.
But
I
I
think
it's
important
to
note
that
it's
not
just
about
data.
B
A
Yeah-
and
so
you
mentioned
a
few
services
there-
that
that
smart,
that
oracle
networks
provide
for
smart
contract
networks.
Are
there
other
services
that
that
or
you
know,
can
you
make
it
sort
of
concrete?
What
are
the
kinds
of
services
that
that
smart
contracts
might
pull
into
so
things
like
data
feeds
and
so
on?
But
are
there
other
other
kinds
of
things
that
are
that
make
in
interesting
networks
like
I've,
seen,
randomness
and
and
things
like
that.
B
B
Today
we
had
some
great
news
that
you
know
the
associated
press
is
launching
an
official
chain
link
to
provide
their
data
about
economics
and
their
data
about
you
know
various
other
kind
of
real
world
events
that
previously
have
not
been
in
a
blockchain
at
that
quality
and
and
in
an
assigned
form
and
and
then
it
also
expanded
to
various
smaller
computations.
So
random
number
generation
is
is
a
great
example.
A
random
number
generator
is,
you
know
the
verified.
B
A
That's
awesome
and
congratulations
really
exciting,
on
on
being
able
to
pull
in
all
of
this
real
world
rich
data,
you
know
for
from
different
economic
facts
and
election
results,
and
so
on.
That's
super
cool
digging
into
the
beta
feeds.
Are
there
kind
of
you
know,
one
of
the
things
that
things
that
falcon
is
really
good
for
is
just
massive
scale:
data
storage.
B
Yeah,
so
I
know
that
the
the
the
file
coin
network
continues
to
grow
and
holds
many
valuable
data
sets
and,
and
there's
a
lot
of
work
there
around.
How
do
you
get
the
the
data
out
of
the
the
file
coin?
Decentralized
storage
system
into
various
into
powering
various
smart
contracts?
There's
weather
data
iot
data?
There's
a
number
of
different.
You
know
exciting
data
data
topics
that
I
think
are
are
useful
and
and
going
to
be
and
are
being
used
for
various
more
advanced,
smart
contract
use
cases.
B
Their
goal
also
isn't
to
generate
a
form
of
consensus
for
persistent
long-term
data
storage.
Their
goal
is
to
just
kind
of
generate
the
consensus
around
you
know
the
validation
of
data
or
random
number
or
devops
task
or
cross-chain
movement,
or
something
and
the
actual
persistence
doesn't
doesn't
really
want
to
stay
in
the
oracle
network.
B
That's
not
going
to
be
as
efficient,
and
that's
not
really
the
point
and
and
really
actually,
I
think
it's
important
for
different
projects
to
carve
out
and
really
focus
on
in
a
very
clear
way
on
specific
parts
of
the
decentralized
stack.
So
I
see
oracle
networks
and
and
various
chain
link
networks
getting
substantial
amounts
of
data
from
file
coin.
I
see
them
writing
other
substantial
amounts
of
data
into
the
decentralized
storage
network
that
that
is
filecoin
getting
the
benefit
of
decentralized.
B
You
know
persistent
storage
and
and
beyond
that
I
think,
there's
actually
a
lot
of
other
interesting
combinations
where
you
can
basically
verify
certain
things
on
the
file
coin
network
and
prove
that
they're
there,
maybe
without
having
to
move
all
the
data
elsewhere
and
and
just
a
lot
of
other
interesting
combinations.
One
interesting
one
I
saw
recently
was
providing
insurance
for
file
coin
miners
to
to
create
certain
guarantees
that
the
file
coin
miners
will
actually
be
kind
of.
You
know
guaranteed
to
retain
the
data
at
a
certain
at
a
certain
service
level.
A
Yeah,
it's
fantastic!
What
becomes
possible
when
you
start
coupling
the
ability
to
pull
in
lots
of
data
and
facts
about
the
world
in
in
larger
scales
and
you're,
able
to
connect
that
to
the
computation
of
smart
contracts
and
and
so
on
through
oracle's,
and
you
know
this
is
like
really
building
up
to
something
extremely
powerful
for
the
for
the
whole
world.
You
described
it
as
sort
of
like
the
truth
machine.
B
Sure
sure,
of
course,
I
I
don't
know
exactly
when
this
is
going
to
happen.
I
know
that
adoption
of
decentralized
services,
both
in
the
storage
format
and
in
the
oracle
network
format,
is
happening
now
at
greater
and
greater
scale.
I
know
that
enterprises
are
using
smart
contracts
more
and
more
so.
Those
two
things
I
know
are
happening,
the
the
dynamic
of
of
the
truth
machine
and
the
value
of
cryptographic.
B
Truth,
I
think,
really
depends
on
the
point
at
which
society
decides
that
it's
important
for
a
certain
part
of
society
to
work
a
certain
way
and-
and
what
I
mean
by
that-
is
that
the
way
that
society
works
in
many
different,
specific
verticals
or
industries
or
ways
of
doing
things
in
like
specific
formats,
whether
it's
ad
networks
or
social
media
or
trading
or
real
estate
is
is
the
dynamic
is
pretty
much.
We
told
you
one
thing
we
did
another
and
we
told
you
one
thing:
we
did
another
again
right.
B
B
There
will
be
enough
of
these
kind
of
we
said
one
thing,
but
we
did
another
events
like
imagine
if
there
were
five
robin
hoods
back
to
back
month
after
month
or
imagine
if
there
were
like
20
ever
grandes
back
to
back
every
week,
people
in
that
part
of
the
world
would
decide.
Look
this
kind
of
say.
One
thing:
do
another
model
doesn't
really
work
for
us
anymore.
We
we
actually
need
to
know
your
solvency.
We
actually
need
a
guarantee
that
you
can't
hold
trading.
B
The
the
truth
itself
is
is
generated
through
oracle
networks.
It's
then
fed
into
unchained
state
that
defines
outcomes
and
then
it's
stored.
You
know
the
the
results,
or
you
know
the
things
that
people
want
to
be
persistent
are
stored
in
decentralized
storage
networks,
so
such
as
file
coin
right.
So
the
the
truth
machine
is
what
I
think.
B
Consumers
and
users
will
get
from
all
of
this
work
that
all
of
us
are
doing,
and
eventually
there
will
be
a
flip
and
the
flip
will
not
be
hey.
We
want
to
make
a
crypto
startup
or
hey
we're
an
enterprise,
and
we
want
to,
you
know,
compete
with
other
enterprises,
it'll
be
I'm
a
consumer
and
I
only
want
to
do
trading
or
I
only
want
to
buy
real
estate,
or
I
only
want
to
use
a
payment
system
if
it
gives
me
a
cryptographic,
guarantee
and
and
that'll
require
private
keys.
B
The
truth
machine
in
the
form
of
oracles,
smart
contracts
and
decentralized
storage,
and
when,
when
that
flip
in
society
happens,
that's
when
it's
going
to
be
like
like
email
right.
If
you
don't
have
email,
good
luck,
conducting
transactions,
it's
going
to
be
the
same
dynamic,
except
for
this.
This
cryptographic
truth.
A
Yeah
looking
forward
to
to
to
that
future-
and
I
think
one
of
the
the
things
that
is
going
to
help
us
get
there-
that
I
think
a
lot
of
people
are
super
excited
about,
is
channeling
2.0
and
that
you
know
brings
out
in
sort
of
these
hybrid,
smart
contracts
and
so
on.
Can
you
tell
us
a
little
bit
about
that?
How
do
those
work.
B
Sure
so
so,
hybrid
smart
contracts
are
the
name
we
we
have
in
the
in
the
paper
for
the
more
advanced
version
of
smart
contracts,
which
is
actually
a
collection
of
different
systems
and
cryptographically
guaranteed
services
that
make
the
advanced
version
of
a
smart
contract
right.
So
the
definition
of
a
smart
contract
over
time
has
expanded
right.
When,
when
you
and
me
started,
a
smart
contract
was
one
piece
of
code
that
did
one
thing
probably
generate
a
token.
It
didn't
have
a
multi-sig,
it
didn't
have
a
dow
voting
contract.
B
B
Web
2.0
web
applications
that
function
at
a
high
level
of
value
for
users
and
at
scale
and
speed
and
security
they're
composed
of
hundreds
of
services
right,
there's,
a
ton
of
internal
services
that
were
written,
there's
a
ton
of
external
services
from
from
different
places
right.
So
what
a
hybrid
smart
contract
is
is
a
smart
contract
that
isn't
just
about
hey,
there's
this
piece
of
on-chain
code
or
there's
these
two
pieces
of
on-chain
code.
It's
hey!
There's
this!
B
There's
these
five
pieces
of
on-chain
code
over
here,
there's
20
other
pieces
of
on-chain
code
and
20
other
chains
to
take
people's
money
and
give
them
back
yield.
There's
five
oracle
networks
all
performing
different
functions,
two
giving
data
one
generating
cross-chain
interactions,
one
generating
keeper
events,
one
generating
some
kind
of
anti-fraud
mechanism
and
by
the
way
everything
that's
going
on,
is
being
persistently
stored
in
a
decentralized
storage
mechanism
like
like
file
coin,
and
this
this
is
what
a
hybrid
smart
contract
is
and
and,
logically
speaking,
right
and
it's
not
even
logically
speaking.
B
This
is
what
defy
is
right.
D5
is
a
hybrid
smart
contract
which
is
which
is
partly
why
defy
uses
so
so
many
oracles,
because
without
oracle's
d5
can't
exist.
So
so
all
of
the
more
advanced
use
cases
are
are
going
to
be
hybrid,
smart
contracts
and
the
the
interesting
thing
is
that
those
failures
like
the
robin
hood
failure,
basically
brought
in
a
crop
of
people
that
weren't
necessarily
interested
in
tokenization.
B
A
Yeah
extremely
well
put
and
speaking
of
of
use
cases,
part
of
what
is
gonna,
help
build
out
the
truth
machine
and
it's
gonna
leverage,
the
the
hybrid
smart
contracts
and
all
these
apis
that
that
people
are
building
over
time
is
developers
out
there.
So
we
have
both
the
chainlink
community
and
the
falcon
community.
A
Have
you
know
many
thousands
of
developers,
probably
tens
of
thousands
of
developers
together
and
those
developers
experimenting
with
with
the
tools
and
the
tech
and
so
on,
coming
up
with
new
use
cases
coming
up
with
new
applications,
and
so
in
experimenting
is
what
ends
up
building
the
new
kinds
of
applications
that
that
are
gonna.
You
know,
flesh
out
and
improve,
improve
the
world
and
make
the
truth.
Machine
have
have
an
impact,
something
that
we've
been
spending
a
bunch
of
interesting.
A
bunch
of
time.
A
A
It
was
a
huge,
huge
success
and,
and
you
know
one
of
the
really
cool
things
that
happened
out
of
that
was
many
of
those
of
the
participants
in
that
in
that
hackathon
went
on
to
develop
their
their
hacks
into
applications
and
businesses
and
went
into
the
the
one
of
the
several
accelerator
programs,
and
I
think,
nine
of
them
at
least.
I
know
of
at
least
nine
participants
in
the
in
the
chain
link
spring
hackathon.
A
A
So
I'm
mentioning
these
because
they're,
you
know
they're
example,
builders
and
example,
applications
that
came
out
of
of
that
hackathon
and
is
gonna,
and
they
are
now
off
to
the
races
building
one
of
these
applications
helping
improve,
improve
tech
and
improve
use
cases
and
whatnot
and
tomorrow
I
I
know
that
your
fall
hackathon
is
starting
and
that
now
has
went
from,
like,
I
think,
100k
in
prices
in
the
last
one.
Now.
B
B
B
So
we've
had
multiple
people
raised
multiple
multi-million
dollar
rounds
from
the
previous
hackathon,
and
this
hackathon
seems
to
be
substantially
larger,
like
anywhere
from
50
to
100,
100
percent,
larger.
We
in
terms
of
the
prices
and
the
sizes
of
the
of
the
you
know,
amount
of
developers
in
in
any
case.
I
I
think
that
our
approach
to
all
of
this
is
that
the
developer
community
is
really
going
to
take
the
infrastructure
that
you
and
I
have
worked
on
for
many
years
and
turn
it
into
something
useful.
B
It's
going
to
be
those
developers
that
that
create
the
use
cases
that
bring
the
value
of
of
all
of
this
to
to
to
the
average
person
and
developed
emerging
and
various
markets.
So
you
know,
I
really
appreciate
the
way
the
file
coin,
community
approaches
supporting
developers
and-
and
we
have
a
very
strong
focus
on
that
as
well.
B
So,
if
you're,
if
you're
very
early
in
your
career
in
terms
of
learning
smart
contracts
or
learning
how
to
build
decentralized
applications,
you
should
attend
the
hackathon
and
and
get
going
because
there
are
people
that
started
that
way
and
now
have
actual
projects
that
got
funded
and,
if
you're
far
along
then
there's
a
there's,
a
lot
of
cutting-edge
presentations
from
top
protocol
teams
and
and
various
other.
You
know
kind
of
benefits
to
to
doing
the
the
experience
track.
So
I
encourage
everybody
to
go
check
it
out
and
it's
gonna
be.
A
It's
a
it's
a
huge
success
so
far
in
all
of
the
builders
and
in
the
last
hackathon
I
can't
wait
to
see
what
people
are
going
to
build
in
this
one.
It's
super
exciting
to
to
see
all
the
participation,
and
I
think
this
will
just
continue
to
compound
well
into
next
into
the
into
next
year
and
the
year
after
that
and
so
on,
and
I
think
we
can
really
build
up
a
really
great
application
kind
of
like
reactor
where,
like
you,
people
can
come
together.
A
Experiment
with
it
with
the
tooling
get
mentorship,
try
things
out,
build
something,
and
if
that
thing
has
has
legs
and
it
can
be
successful-
then
go
on
to
to
accelerate
your
programs
and
raise
funding
and
so
on.
So
yeah
definitely
participate
reach
out
to
us.
If
we
can
be
helpful
and
so
on,
are
there
any
applications
that
you
would
love
to
see
built
in
the
hackathon?
Any
ideas
that
you
would
throw
out
there.
B
Yeah,
so
I
I
think,
there's
two
categories
that
are
that
are
still
underutilized,
but
have
a
lot
of
potential.
One
is
something
called
chain-link
keepers
where
you
can
actually
do
certain
amounts
of
off-chain
compute
in
oracle
networks
called
keeper
networks
and
and
that
actually
greatly
expands
the
scope
of
what
you
can
efficiently
build
in
the
form
of
a
smart
contract
or
a
hybrid
smart
contract,
as
I
defined
it
earlier
and
the
other
one
is
the
individual
data
providers
that
sign
data
right
now
and
provide
it
from
from
from
themselves
as
a
data
provider.
B
As
I
said
today,
and
the
associated
press
announced
that
they're
launching
their
own
official
chain
link,
node
and
so
you'll
be
able
to
get
election
results.
You
know,
gdp
inflation
indicators,
any
number
of
pieces
of
data,
and
so
there
isn't
just
market
data
and
there
isn't
just
randomness,
that's
kind
of
the
the
spike
in
the
long
tail.
But
then
there's
the
long
tail
of
all
the
things
that
you
could
build
using
various.
You
know
specific
individual
data
sources.
We
have
data
sources
about
real
estate
prices.
B
Possibly
you
know
mixed
with
with
market
data
mixed
with
the
defy
aspect,
the
those
are
the
permutations
where
I
think,
a
lot
of
unique
and
previously
unseen
things
will
come
out
of,
and
I
think
that
there's
a
lot
of
lot
of
different
trust
issues
that
can
be
solved
through
those
permutations.
So
I
I
would
actually
look
at
the
newer
functionality
and
the
newer
data
sets
and
I
would
think
about
hey.
B
Nobody
has
ever
had
this
data
set
on
a
blockchain
or
nobody
has
ever
had
this
ability
to
generate
this
type
of
trust,
minimized
off
chain
compute
into
a
hybrid
smart
contract.
How
can
I
use
this
new
capability
to
generate
something
something
new
and
novel
and-
and
I
think
that'll
be
that'll-
be
impressive?.
A
A
Thank
you
for
all
of
what
you
and
and
the
entire
team,
the
set
of
teams,
building
chain
link
and
all
of
the
infrastructure
and
all
the
oracle
networks
are
doing
is
like
a
really
critical
part
of
the
future
of
web3
and
making
making
the
truth
machine
reality
and
help
helping
it
be
impactful
in
the
world.
So
a
huge
pleasure,
as
always
great,

chat

you.
It's
