From YouTube: The Filecoin/Zcash Partnership: It's About Scalability
Description
Last month, Protocol Labs, Electric Coin Co. and the Ethereum Foundation announced a partnership for R&D into Halo 2, ECC's recursion system for Zcash. While many know Zcash as a privacy-enhancing cryptocurrency, Halo 2 is also a marvel for blockchain scalability. In this keynote panel, you'll hear more from Zcash creator Zooko Wilcox and Chair of the Filecoin Foundation Marta Belcher.
A
Hi,
thank
you
so
much
for
the
introduction
I
am
so
excited
to
be
here
with
zuko
and
with
bailey.
Of
course,
as
bailly
said,
zuko
really
goes
without
needing
an
introduction,
as
one
of
the
founders
of
zcash
and
the
ceo
of
the
electric
coin
company,
which
is
one
of
the
companies
that
supports
zcash
today
and
I'm
so
excited
to
be
back
on
stage
with
zuko.
A
A
B
But
there's
another
aspect
to
halo:
that's
not
yet
been
explored,
which
is
the
scalability
benefits
and
recursion,
like
you
ask,
is
the
key
to
that
so
as
zero.
So
let
me
try
to
explain
briefly
what
recursion
in
a
zero
knowledge
proof
system
is
a
zero
knowledge.
Proof
system
is
a
way
to
which
many
of
you
might
already
know,
because
it's
it's
so
important
to
file
a
coin
already.
B
A
zero
knowledge
proof
system
is
a
way
to
prove
like
a
set
of
facts
without
revealing
any
of
the
information
in
there
just
to
prove
the
truth
of
the
overall
package
of
facts,
and
that
means
there's
there's
some
deep
connection.
Actually,
I
think
mathematically
between
scalability
and
privacy,
because
in
computer
science
scalability
is
really
about
not
transmitting
or
computing
on
unnecessary
information
right
and
privacy
in
a
sense
is
about
not
leaking
or
disclosing
or
transmitting
unnecessary
information
or
information
that
you
don't
want
to
share.
B
So
there's
some
interesting
mathematical
connection
now
recursion,
so
halo
was
the
first
zero
knowledge
proof
system
that
was
trustless,
meaning
there's
no
there's
nobody
who's
responsible
for
setting
it
up,
and
you
have
to
rely
on
those
people
not
to
cheat
or
anything
like
that.
It's
just
pure
math,
with
no
special
parties
involved.
So
it's
trustless
halo
was
the
first
zero
knowledge
proof
system,
which
is
both
trustless
and
capable
of
recursion.
B
B
Now
you
can
give
someone
else,
a
proof
that
my
proof
is
true,
plus
other
things
are
also
true
and
that
is
potentially
a
really
powerful
building
block
for
scalability,
because
now
there's
no
limit
to
the
size
of
the
data
set
that
you
can
prove
facts
about
with
us
with
a
one
efficient
proof.
Does
that
make
sense.
A
A
First
of
all,
we
think
unlocking
recursion
halo
for
the
reasons
you've
talked
about
is
very,
very
cool
and
also
we're
really
excited
to
explore
how
halo
might
be
used
in
the
file
coin
and
ethereum
ecosystems
to
really
improve
the
scalability
and
efficiency
the
way
you're
talking
about
and-
and
we
really
think
that
cross-chain
proof
verification
could
really
unlock
a
lot
of
possibilities
for
all
three
of
these
networks.
So,
for
example,.
A
B
Yeah
well
both
the
immediate
thing
that
we've
already
started
doing
together,
which
is
implementing
the
recursion
and,
like
I
said,
halo
itself,
is
already
in
the
process
of
getting
deployed
to
zcash
mainnet.
It's
scheduled
to
go,
live
on
zcash
mainnet
in
january
2022,
but
that's
not
the
recursive
part.
That's
only
for
just
strengthening
the
core,
but
then
probably
the
next
live
deployment
of
halo.
B
The
the
possibility
of
that
making
like
the
purpose
of
web3
in
general
and
filecoin,
ethereum
and
zcash,
is
to
make
a
more
democratic
world
where,
like
a
world
based
on
consent
and
everyone
can
opt
in
or
opt
out
or
choose
how
they
want
to
use
it
and
it
does
what
they
want
for
their
purposes,
not
serving
some
like
corporate
monopoly
or
something.
And
for
that
to
work.
B
We
really
need
scalability,
because
we
need
to
be
able
to
provide
it
to
lots
and
lots
of
people
at
low
cost
and
that's
what
scalability
is
for
and
then
I'm
also,
let
me
keep
going
on
things
I'm
excited
about.
I'm
also
really
excited
about
something
else
you
mentioned,
which
is
sort
of
the
yet
to
be
discovered.
B
Applications
of
this
technology,
like
you
mentioned
cross
chain
interop,
and
that's
really
interesting,
because
if
you
have
the
ability,
if
you
have
recursive
proofs
now
you
have
the
ability
to
prove
arbitrarily
complicated
data
structures
that
includes
you
can
prove
the
entire
history
and
state
of
an
entire
blockchain
in
a
single
proof,
and
we've
already
demonstrated
that
and-
and
that
implies
maybe-
and
this
is
where
we
get
into
what's
fun.
For
me
as
a
technologist-
is
exploring
new
things
and
trying
new
things
and
finding
out
if
they
work
and
how
you
know
what
the
results
are.
B
So
maybe
with
that,
we
can
do
what
you
were
saying
about
use
this
fundamental
technology
as
a
way
for
other
blockchains
to
sort
of
assess
the
state
or
and
the
correctness
of
the
state
of
other
blockchains,
because
you
I
can
give
you
a
proof
that
says
here's
a
proof
of
the
entire
history
of
the
zcash
blockchain.
In
one
little
data
chunk
and
now
the
ethereum
and
file
coin
blockchains
can
process
that
and
vice
versa.
So
that's
exciting
and
there
might
be
other
applications
too.
B
Oh
yeah,
I
think
about
it.
I
think
a
little
differently
than
most
people
do
a
lot
of
people.
Think
of
privacy
as
like
secrecy
like
having
high
op
sec,
and
I
don't
know,
locking
your
doors
with
better
locks
or
you
know
higher
more
security
or
more
secrecy
or
being
more
closed
about
what
you
share
or
anything
like
that,
and
I
don't
think
about
that.
That's
not
what
privacy
means
to
me
at
all
to
me.
B
Privacy
is
just
about
consent,
it's
like
if,
if
like
you
choose
who
in
your
life,
you
want
to
share
stuff
with,
like
you
know,
you're
having
a
baby
or
you're,
you
know
you're,
sick
or
anything
in
your
life.
It's
up
to
you
who
you
share
with
anybody
else,
making
that
decision,
for
you
that's
just
wrong
right,
but
if
you
choose
to
share
things
either
with
a
lot
of
your
friends
or
if
you
choose
to
post
things
in
public
to
me,
that's
actually
the
same
thing.
That's
your
consent!
B
That's
something
that
web
3
needs
to
enable
everyone
to
do
to
share
and
to
share
selectively
on
their
own
terms.
So
privacy
to
me
is
just
about
consent,
and
it's
just
inextricable
like
all
of
web
3
is
about
privacy,
because
it's
about
empowering
the
individual
to
have
their
own
agency
honored
by
the
tools
that
serve
them.
A
I
love
that
that's
such
an
interesting
perspective
on
it
and
that's
that's
a
that's
a
just
a
great
way
of
thinking
about
it
and
you
know
just
for
me
for
me
personally
really.
I
think
I've
been
really
concerned
over
the
last
year
with
just
increasingly
seeing
how
regulators
are
are
thinking
about
privacy
and
and
anonymity.
I
think
there's
this
sort
of
misconception
among
regulators
that
you
know
anonymity
or
privacy
are
bad
or
illegal.
B
A
B
A
You
know,
I
think
I
think
it's
important
for
people
to
understand
that
privacy
and
anonymity
aren't
bad
or
illegal
they're,
absolutely
essential
for
civil
liberties
and
that's
especially
true
for
financial
transactions.
It's
not
an
exception.
It's
especially
true
for
financial
transactions.
Right
yeah-
and
I
remember
you
know
I
always
talk
about
pictures
that
I
saw
from
the
hong
kong
protest,
which
really
sort
of
hit
me
and
and
really
drove
this
point
home.
A
For
me,
which
was
there
are
these
pictures,
where
there
were
these
long
lines
at
the
subway
stations,
where
the
pro-democracy
protesters
were
waiting
to
purchase
tickets
with
cash
so
that
their
electronic
purchases
wouldn't
be
placing
them
at
the
scene
of
the
protest,
and
so
for
me
that
really
underscores
that
you
know
cashless.
Society
is
a
surveillance
society
and
the
absolute
importance
of
you
know
anonymous
transactions
for
civil
liberties,
so
yeah.
B
B
It
was
trump's
doj
that
wrote
that
paper
that
you
described,
and
I
think
I'm
seeing
something
going
on
right
now
that
I
saw
in
the
late
1990s
with
the
launch
of
the
world
wide
web
and
the
2000s
like
about
10
years
along
in
there,
which
is
that
some,
like
regulators,
have
a
lot
of
different
mandates
right.
So
the
law
enforcement
and
national
security
regulators,
both
over
the
last
year
in
their
papers
and
acronyms
or
the
last
two
years,
and
also
in
the
late
1990s.
B
They
had
this
opposition
to
encryption
right
and
they
they
meaning
the
fbi
and
the
nsa
mostly
opposed
the
deployment
of
encryption
for
the
world
wide
web
at
first,
and
they
were
successful
at
blocking
it
with
a
lot
of
dirty
tricks
and
different
kinds
of
campaigning
and
politics.
It
was
all
very
interesting.
I
was
involved
as
a
as
a
foot
soldier.
I
like
sat
at
my
terminal
writing
code.
It's
my
contribution,
but
then
it's
interesting.
What
happened
back
then,
because
I
think
I
see
the
same
thing
happening
today.
B
What
happened
back
in
through
the
deployment
of
the
world
wide
web
is
there
was
this
policy
battle
like?
Are
we
going
dark?
Can
criminals
exploit
this
new
web
thing
and
then
what
happened
was
web
1.0
happened
and
people
started
using
the
world
wide
web
for
commerce
and
for
chatting
with
their
grandchildren
and
normal
stuff?
B
It
started
to
become
important
for
people's
lives
and
important
for
our
economy,
and
once
that
happened,
I
think
that's
what
turned
the
tide
and
the
national
security
and
law
enforcement
sort
of
mandates
within
government
gave
way
to
other
mandates
within
government
like
consumer
protection
and
national
competitiveness
and
like
having
a
prosperous
economy
and
like
protecting
people's
grandmas
when
they're
using
their
computers
and
all
that
stuff,
and
I
actually
I
could
be
wrong.
I
hope
I'm
not
wrong.
B
I
have
been
predicting
this
and
I
think
I
see
it
happening
and
so
we'll
find
out
in
like
five
years.
If
I
was
wrong
or
right
when
we
look
back
on
this
video,
but
what
I
think
I've
seen
happening
is
that
transition
is
starting
to
happen
with
cryptocurrencies
like
two
years
ago,
three
years
ago,
four
years
ago,
cryptocurrencies
were
like
the
world
wide
web
was
in
1997..
B
These
weird
geeks
use
it
like
government
people
don't
use
it.
They
didn't
use
the
internet
in
1997
right,
you
had
to
like
fax
them
or
whatever
they
didn't
have
an
email,
and
then
you
know
by
like
2001
or
whatever
everyone
had
email
and
and
that
changed
the
whole
conversation,
and
I
think
I
see
the
same
thing
happening
with
cryptocurrencies,
because
there's
a
huge
regulatory
policy
debate
happening
in
the
united
states
and
elsewhere
about
cryptocurrencies,
but
it's
no
longer
up
primarily
about
law
enforcement.
Now,
there's
a
whole
bunch
of
talk
about
consumer
protection,
national
competitiveness.
B
You
know
international,
like
the
globalization
or
localization
of
the
world
financial
stability
and
having
an
economy
with
like
jobs
and
savings
and
protection
for
all
the
citizens.
Anyway.
So,
you're
right
that
some
regulators
have
spoken,
they
haven't
done
anything
but
they've
spoken
about
encryption
as
being
dangerous,
but
that's
not
most
of
the
regulators
actually,
and
so
I
think
the
tide
has
shifted,
we'll
see.
What's
going
to
say.
Oh
so
in
fact,
we've
already
seen
how
zcash
is
like
accepted
or
approved
or
regulated
by
a
lot
of
the
regulators.
B
B
B
That's
the
way
we
do
things
in
america
right,
like
civil
liberties,
are
not
the
principle
of
the
chinese
communist
party,
so
they're
being
very
consistent
in
the
way
they're
treating
technology
and
everything
else
they
do.
But
the
american
way
is
that
civil
liberties
are
an
important
part
of
like
the
safety
and
the
prosperity
of
our
whole
society,
and
I
really
agree
with
you
that
civil
liberties
are
fundamental,
and
it's
also
like
we
said
earlier-
that's
like
what
web
3
is
about.
A
Yeah,
absolutely
absolutely,
and
so
I
guess
you
know
just
to
sort
of
so.
First
of
all,
I
hope
you're
right.
That's
that's
a
really
interesting
perspective.
I
think
it's
a
really
really
interesting
perspective,
and
I
I
guess
that
sort
of
leads
into
a
really
big
picture.
Question
that
I
I
really
had
wished.
We
got
to
dive
into
a
little
more
at
mainnet,
and
so
since
we
have
a
few
minutes
left,
I
would
just
love
to
hear
about
your
vision
for
the
future
of
web.
3..
B
Well,
I
guess
I
I
don't
have
a
very
clear
vision
of
the
future.
I
think
it
will
be
very
surprising
to
me
and
everyone
else,
and
that's
actually
one
of
the
things
I
love
about
web3-
is
that
it
respects
users
agency
more
so
that
you
know
the
little
nudges
and
the
you
know
the
structure
of
it
is
designed
to
support
what
its
user
wants,
instead
of
to
fit
its
user
into
some
monopolies
like
profit
model,
and
but
that
means
I
think
it's
going
to
be
that
much
bigger
than
web
2..
B
I
I
think
that,
having
a
like
four
four
or
however
many
companies
controlling
everything,
actually
really
limits,
how
much
value
people
get
and
how
much
they
use
it,
how
much
money
it
makes
how
many
jobs
it
makes.
So
I
think
it's
web
3
is
going
to
be
a
lot
bigger
and
I
think
it's
going
to
be
a
lot
more
diverse.
I
think
humans
are
infinitely
unique
right.
Every
human
is
unique
and
I
think
web
3
is
going
to
provide
a
satisfying.
B
A
Look
forward
to
seeing
that
awesome
yeah,
I
I
cannot
agree
more
and
I
I
think
the
points
you're
making
about
really
fundamentally
the
issues
with
having
these
central
intermediaries
and
and
experiencing
so
much
of
our
lives
through
just
a
handful
of
corporations
and
and
really
having
no
choice
but
to
trust
those
corporations
to
keep
our
data
safe
and
protect
our
civil
liberties,
and
you
know,
serve
us
the
content.
That
is,
you
know
real
original,
like.
