From YouTube: Joseph Lubin // An Ethereum Interview Series
Description
We sat down with Joseph Lubin, one of 8 founders of the Ethereum project and the founder of ConsenSys, to discuss building out applications on the Ethereum blockchain. This series focuses on trying to explain Ethereum to a non-technical audience.
A
So
hi
my
name
is
Joseph
Ruben.
My
background
technology
and
finance
did
robotics
machine
vision,
neural
nets,
research
for
a
number
of
years
did
lots
of
software
engineering
took
me
eventually
to
work
for
a
while
at
Goldman
Sachs
shortly
after
Goldman
Sachs
I
sort
of
pivoted
to
the
world
of
finance.
A
friend
of
mine
asked
me
if
I
would
join
him
in
starting
a
hedge
fund
or
set
of
hedge
funds
and
I
started
to
become
more
aware
of
the
world
of
Finance,
which
I
thought
was
kind
of
silly
for
most
of
my
career
I'd.
A
Let
that
my
econ
major
friends
were
wasting
their
time
and
technology
was
the
only
thing
was
interesting,
but
I
learned
about
the
bigger
game
and
enjoyed
it
and
got
involved
in
different
kinds
of
trading
and
that
sort
of
took
me.
It
basically
made
it
so
be
impossible
for
me
to
miss
Bitcoin
and
so
came
aware.
Bitcoin
pretty
early
and
I
saw
the
the
implications
when
I
read
the
Satoshi
whitepaper
implications
for
how
it
could
transform
society.
A
Essentially,
decentralizing
technologies
wasn't
until
I
heard
that
Alex
white
paper
describing
the
etherium
ecosystem
that
it
really
crystallized
how
we
could
build.
It
is
not
quickly
but
directly,
but
we
could
actually
start
to
implement
use
cases
in
many
different
niches
in
many
different
business.
Social
economic
sectors
on
this
block
chain.
Basically
centralize,
all
the
things
puzzle,
core
value
proposition
of
aetherium-
is
that
it
essentially
represents
a
non
reputable.
Something
that
you
can't
say.
I
didn't
say
that
to
on
sensible,
shared
source
of
truth,
it
essentially
represents
like
the
first.
A
General
purpose
world
computer,
and
so
it
is
because
of
the
mathematics
of
the
situation,
because
everybody
can
excuse
me,
everybody
can
have
a
piece
of
work
can
have
all
of
the
data.
Everybody
can
see
all
the
business
logic
that
affects
the
data.
Everybody
can
trust
it.
No
minority
actor
can
improperly
affect
the
data
or
the
system
so
trustful
computing
transparency.
I
was
one
of
eight
founders
of
the
etherium
project.
Didn't
worked
on
that
for
quite
a
while
about
20
to
23
months
ago,
I
ramped
down
my
participation
on
that
project
and
ramped
up
consensus.
A
I
was
confident
that
that
project
was
going
to
deliver
version
one
of
the
theorem,
but
it
wasn't
in
the
purview
of
that
project
to
build
lots
of
decentralized
applications
to
build
at
the
application.
Layer
was
more
focused
on
the
protocol.
There
wasn't
in
that
the
purview
of
that
organization
to
build
for-profit
projects
or
companies,
so
I
started
consensus
to
do
exactly
that,
to
build
to
projects
products,
companies
for
the
public,
if
they're
in
blockchain
and
and
those
are
things
that
can
also
be
deployed
on
private
permissioned,
theorem
block
chains.
A
A
couple
of
different
insurance
companies,
general
financial
services,
applications,
health
care,
energy,
industry,
music,
industry
supply
chain
management,
the
consensus
we're
going
to
keep
building
projects,
products
for
the
public,
blockchain
and
private
blockchains.
There's
an
enormous
amount
of
infrastructure
to
build
before
consumers
can
make
good
use
of
this
stuff.
Essentially,
the
internet
was
pretty
much
invented
in
1990
and
became
prominent
in
the
late
90s.
So
I
see
a
similar
adoption
curve,
perhaps
a
little
bit
more
compressed
for
blockchain
for
public
blockchain.
A
In
the
meantime,
there's
a
very
strong
value
proposition
for
lots
of
companies
right
now.
A
lot
lots
of
different
focused
projects
could
be
government
could
be
companies
and
we
are
helping
lots
of
those
interests
build
what
they
want
to
build.
So
a
lot
of
that
stuff
and
a
lot
of
that
stuff,
is
helping
to
fund
end
and
derive
development
of
things
that
will
make
their
way
to
the
public
margin.
A
This
shared
source
of
truth,
this
infrastructure,
that
we
can
all
interoperate
on
whether
we're
software
developers
building
stuff
that
easily
interoperates
with
other
things
or
for
people
who
are
establishing
their
own
identity,
their
own
self
sovereign
identity
and
using
that
as
an
access
point
to
lots
of
different
kinds
of
applications.
Perhaps
like
a
decentralized
Facebook,
that's
going
to
put
all
the
power
into
the
periphery
in
the
hands
of
the
people.
It's
going
to
be
centralized
lots
of
our
systems
and,
yes,
I,
think
that's
a
very
good
thing
for
society.
A
It's
not
clear
that
we
ever
have
to
communicate
the
philosophical
benefits
to
end-users.
We
certainly
have
to
communicate
those
things
to
developers,
but
really
I
was
at
a
blockchain
retreat
in
north
of
Toronto
a
couple
weeks
ago
and
a
bunch
of
people
in
that
room
felt
like
we
needed
some
specific
message,
some
specific
name
for
this
thing
that
we
could
share
with
consumers
and
then
lighten
them.
My
feeling
is
that
this
is
just
the
next
Internet.
A
This
is
world
wide
web
version
3
and
then
we're
going
to
be
delivering
applications
that
look
like
web
page
or
web
applications
or
that
look
like
mobile
applications.
They'll
just
have
this
different
kind
of
database
in
the
backend,
this
much
more
trustworthy
database
that
enables
easy
interoperation
amongst
lots
of
different
things.
