From YouTube: Greg Colvin // An Ethereum Interview Series
Description
We sat down with Dr. Greg Colvin, who works on the Ethereum Virtual Machine (EVM) for the Ethereum Foundation. We discusses the role of the EVM, the community, and the implications of blockchain as a technology. This series focuses on trying to explain Ethereum to a non-technical audience.
A
I'm
Greg
Colvin
I'm
working
for
the
foundation
right
now,
you
know
technically,
is
a
part-time
contractor,
trying
hard
not
to
let
it
completely
take
off
of
my
life,
which
seems
to
be
a
strong
danger
with
the
theory
and
anyone
who
gets
into
it.
It
just
seems
to
take
over
my
main
job,
I've
narrowed,
doing
and
just
to
EVM
the
interpreter
for
the
EDM
and
trying
to
get
as
much
efficiency
out
of
that
as
I
can
what's
cool
about
as
far
as
the
etherium
goes.
Is
that
it's?
A
A
What
the
value
of
ether
is
whether
it
goes
up
or
down
it's
just
the
fuel
that
runs
the
Machine
and
so
what's
interesting
is
the
things
you
can
do
with
it,
and
that's
where
the
EVM
is
actually
running
the
little
pieces
of
code
that
let
people
do
all
the
various
amazing
things.
They've
been
talking
about
for
the
last
three
days,
a
lot
of
which
just
goes
past
me,
because
they're
yeah
all
kinds
of
different
businesses,
so
here's
somebody
doing
some
sort
of
you
know
validated
notary
stuff.
A
Business
is
really
neat
I,
don't
know
why
they
need
it,
but
they
do
and
apparently
they
can
do
it
on
a
blockchain
much
better
than
they
can
do
it
other
ways
and
you've
been
here
too.
So
you
know
just
how
many
presentations
there
been
just
idea
after
idea,
after
idea,
that
would
not
be
possible,
except
that
we
have
a
programmable
blotching
and
so
apparently
I'm
just
at
the
sort
of
the
heart
of
that
the
kernel
and
as
I
was
saying,
it's
a
strange
place
to
be
cuz.
A
People
will
ask
me
other
things
about
a
theory
and
then
it's
like
my
own.
You
know
I
tried
to
read
the
yellow
paper.
I
went
to
the
appendix
with
the
opcodes
and
the
gas
cost
function
that
I
sort
of
understand
those,
and
that's
all
I,
really
need
to
understand.
There's
something
called
delicate
palm.
It
goes
away
and
does
something
they
order,
something
called
gas.
It
returns
a
number.
A
So,
for
me,
the
rest
of
ether
reom
is
just
sort
of
a
black
box,
which
is
probably
a
multi-dimensionally,
inverted
view
because
for
other
people
the
VM
is
just
a
black
box
and
the
rest
of
the
system.
They
understand.
But
somehow
the
other
program
goes
into
this
black
box
and
it
does
computation,
it
comes
out
and
you
know
more
understand
it.
Then
they
understand
the
CPU
in
their
smartphone.
So
there's
a
very
large
number
of
questions
you
could
ask
me.
A
A
A
Even
I
still
have
trouble
wrapping
my
head
around
that
it's
like
someone
will
say
well,
the
Sun
is
more
likely
to
supernova
and
I'm
still
going.
No,
no
I
don't
want
that.
I
want
certainty.
I
want
absolute
mathematical
certainty,
the
program
runs
and
it
gives
a
result
period
and
you
have
to
drop
that
in
a
lot
of
crypto
stuff
and
say
no
we're
dealing
with
probabilities
and
the
probabilities
are
so
overwhelming.
You
just
don't
worry
about
it
and
it
works.
A
A
It
was
a
relatively
small
number
of
technical
people
got
going
with
the
internet,
but
they
were
fairly
senior
people
and
it
seems
a
pretty
young
crowd.
This
jumped
on
this
I.
Don't
know
what
the
average
age
is,
but
it
seems
like
mid
twenties,
sometimes
and
there's
advantages
to
that
there,
just
a
huge
amount
of
enthusiasm
and
energy
and
that's
the
good
side
and
I
think
that's
we're.
Seeing
a
lot
of
that
that
things.
People
are
doing
things
we
just
didn't
know
we're
possible
I.
A
Like
that,
it's
technology
technology
that
works
works,
and
then
you
know
people,
people
being
people
do
what
they
do
with
it.
I
remember
working
at
Oracle
that
really
hits
you've
got
this
database.
You
know
what
are
you
gonna
do
with
it?
Well,
any
government
could
use
it.
What
government
can
use
it
to
be?
You
know
paying
for
people's
healthcare.
Now
the
very
same
government
could
be
using
it
to
keep
track
of
all
of
their
nuclear
weapons.
A
Is
it
a
good
technology
as
an
evil
technology
mountains?
It's
a
database
that
keeps
track
of
stuff.
It's
a
blockchain.
You
put
things
on
it.
What
you
put
on
it,
whatever
you
want,
so
so
it's
a
powerful
technology
that
will
will
have
an
effect
and
make
a
difference,
but
it's
unfortunately
not
up
to
the
technologists
to
know
what
that
is.
