Description
Hyperledger: Building the Future with Blockchain featuring
Brian Behlendorf, Executive Director, Hyperledger
A
This
is
brian
behlendorf,
who
is
the
executive
director
of
the
hyper
ledger
foundation
like
I
said
he
knows
more
about
open
source
than
pretty
much
anybody
I'm
high
billing
for
you.
Thank
you.
We
both
spoke
at
the
natural
National,
Retail,
Federation
and
I'm
this
so
really
awed
by
the
work
he's
done
throughout
his
career.
Not
just
at
the
hyper
legend
foundation.
A
A
There
was,
you
know,
people
caught
confused
within
blockchain
and
cryptocurrencies,
and
then
people
thought
well.
How
real
is
this
and
then
next
thing
you
know
it
seems
to
be
everywhere
right,
so
so
walk
us
through
this
we'll
start
with
the
simple
question:
first,
which
is
you
work
for
the
hyper
ledger
project,
which
is
part
of
the
Linux
Foundation?
What
is
the
hypogeum
project
sure.
B
So
let
me
start
by
explaining
what
the
Linux
Foundation
is.
The
Lynx
foundation
is
a
16
year
old,
501,
C,
6
industry
consortium
of
over
a
thousand
different
businesses
and
tens
of
thousands
of
developers
working
together
to
build
software
products
used
by
tens
of
millions
of
developers
all
across
the
world
in
projects
ranging
from
originally
was
the
Linux
operating
system.
B
Then
it
was
the
use
of
Linux
inside
of
automobiles
and
telco
switches
and
other
high
intensity
environments
than
it
was
cloud
computing
and
software
defined
networking
and
a
whole
long
list
now
of
projects,
including
now
hyper
ledger
focused
on
the
blockchain
space.
We're
with
the
Linux
Foundation,
the
Linux
Foundation
does
is
serve
as
a
neutral
ground
for
the
coming
together
of
developers.
B
B
So
that
list
included
companies
like
IBM
and
Intel
and
Hitachi
and
Fujitsu
and
and
and
Linux
related
startups
to
some
new
players
and
open
source
like
JP,
Morgan
and
Blythe
masters,
digital
asset
company
and
a
number
of
others
and
said:
let's
see
if
we
can
take.
What
really
is
what
most
people
feel
is
the
most
distinctive
part
of
the
the
Bitcoin
stack
or
the
etherium
stack,
which
is
this
underlying
blockchain
technology
and
see?
Are
there
other
ways
to
deploy
it
other
types
of
use
cases?
B
We're
winding
back
a
little
bit
because
the
even
the
word
blockchain
is
pretty
I,
genericized
and
politicized
at
this
point.
But
what
a
blockchain
is
is
a
distributed
ledger.
It's
as
if
you
know,
let's
say
all
of
us
in
this
room,
decide
we're
gonna,
have
a
picnic
on
Saturday
right.
So
one
of
us
starts
a
Google
Doc
shares
it
with
everyone
in
the
room
and
we
say
okay
feel
free
to
add
you
know
whatever
you
want
to
bring
potluck
to
the
picnic
right.
B
B
If
we're
all
we're
doing
is
planning
a
picnic,
but
if
we're
trying
to
run
an
economy
here,
that
kind
of
chaos
isn't
really
good,
but
we
still
need
what
a
Dougal
doc
does
for
everybody
in
this
room
which
just
serve
as
a
system
of
record
serve
as
a
kind
of
database
right.
It's
a
ledger.
It's
a
place
where
we
can
record
things
and
know
everyone
will
see
it
and
actually,
in
many
cases
what
you
want
is
something
you
can
record
that
can't
be
withdrawn.
That
can't
be
pulled
back,
so
it
becomes
a
history
right.
B
It
becomes
a
ledger
of
our
activities
with
each
other
and
that's
what
is
at
the
heart
of
the
coin
in
aetherium?
It's
why
you
can't
spend
the
same
Bitcoin
twice,
because
there's
a
record
of
transfers
from
one
party
to
the
next,
and
it
turns
out
that
that's
useful
in
non
Bitcoin
circumstances.
If
you're
trying
to
track
payments
between
two
JPMorgan
account
holders,
they
can
wait
to
get
it
cleared
through
JPMorgan
system
or
they
can
prove
to
each
other.
B
Hey
I've
got
so
many
JPM
coins
which
map
to
US
dollars,
I'll
just
transfer
them
to
you,
because
you're
also
a
JPM
account
holder.
Now,
that's
one
way
it
can
be
used.
It
could
be
used
by
as
a
replacement
for
projects.
The
organizations
like
Swift
right
so
instead
of
messaging
that
you're
going
to
send
$10,000
from
one
bank
account
to
another
instead
have
that
settled
immediately
on
a
distributed
ledger
now.
B
A
When
I
read
the
JP
Morgan
thing
that
we're
talking
about
how,
if
you
buy
and
sell
stock,
but
the
settlement
process
actually
takes
days-
and
this
way
you
can
settle
pretty
much
instantly.
But
you
know
we
talked
about
blockchain
like
it's
one
thing
and
obviously
you
said
it's
a
distributed
ledger.
But
when
you
look
at
the
hyper
ledger
website,
I
mean
you've
got
all
these
frameworks
and
all
of
the
tools
now,
obviously
we're
gonna
get
in
all
those
and
details.
A
B
You're
right
about
the
the
use
of
that
word,
sometimes
it's
used
without
any
article
in
front
of
it,
which
makes
it
sound
like
a
religion
right,
oh
I,
see
you've
gotten
into
blockchain.
Sometimes
the
definite
article
is
used
before
that
the
blockchain
reports,
an
earlier
kind
of
world
view,
which
said
well.
B
So
some
of
the
projects
that
hyper
ledger
and
we've
got
twelve
different
products.
If
you
want
to
think
of
them
that
way,
but
they're
really
community
is
building
code.
A
couple
of
those
are
projects
like
hyper
ledger
fabric,
hyper,
ledger,
Sawtooth,
hyper,
ledger
Iroha,
which
are
tools
for
running
a
blockchain
network.
B
So
if
you
and
I
and
thirty
people
here
we're
on
this
network,
we'd
each
stand
up
a
node
running
this
software
we'd
all
pointed
at
a
common
certificate
authority,
basically
the
badges
in
and
then
we
start
writing
transactions
with
each
other
onto
this
common
ledger.
Other
tools
there
are
about
implementing
support
for
the
etherium
smart
contract,
language
called
solidity.
Others
are
particularly
distributed,
digital
identity
and
then
you
know
it's
kind
of
a
nerds
paradise.
So
there's.
B
Some
of
them
might
be
system-wide.
You
know
you
want
to
make
sure
that
a
case
can
only
be
closed
once
two
or
three
other
certain
conditions
are
met
or
a
an
insurance
claim
can
only
be
transferred
for
one
party
to
another.
Once
some
other
I
kind
of
sign
off
happens
right,
those
are
things
you
can
write
as
smart
contracts
into
the
system.
You
could
also
model
bespoke
agreements.
Things
like
you
know
an
insurance
claim,
for
example,
or
an
insurance
policy
between
a
farmer
and
an
insurance
company.
B
That
says,
if
there
is
a
drought
in
the
California
Central
Valley
at
the
end
of
the
growing
season,
it's
determined
there's
a
dry.
Then
the
insurance
company
pays,
the
farmer,
$10,000
and
a
smart
contract
might
be
something
that
runs
is
distributed
out
to
the
network.
Every
node
runs
it
at
the
end
of
the
growing
season
on
a
certain
day.
They
all
consult
whether
calm
or
some
commonly
agreed-upon
Oracle
in
this
space,
and
if
it
turns
out
yes,
precipitation,
was
less
than
8
inches
or
something
like
that.
B
Then
the
farmer,
then
a
an
entry
is
written
to
the
blockchain
recording
the
transfer
of
$10,000
from
the
insurance
company
to
the
farmer.
Now
there
might
seem
silly
right.
The
easy
way
to
do
that
is
just
have
the
insurance
company
pay,
the
farmer,
but
what?
If
that
insurance
company
is
not
Allstate
or
somebody,
you
know
highly
reputable,
but
is
an
investor
somebody
you
don't
know
somebody
who
doesn't
have
as
much
reputation.
B
This
is
a
way
to
address,
perhaps
even
eliminate
counterparty
risk
in
a
lot
of
the
transactions
in
the
world,
and
there
are
people
who
say
had
we
had
these
systems
during
certain
other
financial
crises,
we
might
have
perhaps
had
less
of
the
irrational
exuberance
that
gets
talked
about
out
there,
but
perhaps
also
less
of
the
chaos
that
comes
from
an
disorderly
unwinding
of
positions
and
markets.
So.
A
A
B
A
way
of
like
bringing
that
kind
of
verification
of
a
lot
of
things
that
ordinarily,
you
have
to
take
for
granted
right
and
you
know,
without
naming
any
particular
companies
because
I
don't
know
some
of
you
might
all
work
for
them
or
whatever,
but
like
within
almost
every
sector
and
Technology.
There
are
these
800-pound
gorillas
at
the
center.
Most
of
them
do
totally
fine
with
the
Charter
of
being
the
trusted
third
party
in
so
many
of
our
transactions.
But
you
know:
I
come
from
a
school
that
you
know
it
uses
the
phrase.
B
Power
corrupts
right
and
absolute
power
corrupts
absolutely
all
right
and
in
some
industries
I
mean
it
might
be
fine
for
microblogging
or
sharing
cat
photos,
but
for
bank
records
it's
kind
of
not
acceptable
to
have.
You
know
a
central
party
that
owns
all
the
data
and
could
change
it
in
imperceptible
ways
and
that's
what
this
technology
is
designed
doable.
So.
A
B
That
I
could
to
be
any
use
case
for
blockchain
Tekken.
You
can
always
answer
back
to
me.
Couldn't
she
do
that
with
a
centralized
database?
Would
it
and-
and
the
answer
is
always
yes-
it'll
always
be
faster
and
cheaper
and
easier
to
upgrade
and
by
almost
every
IT
metric
could
be
a
better
system.
That
would
be
true
for
Bitcoin
as
well.
If
somebody
just
ran
a
Bitcoin
org
that
kept
track
of
everybody's
Bitcoin
balance,
you
could
have
millions
of
transactions
a
second
and
be
happy
with
it.
B
You
wouldn't
have
all
this
energy
consumption,
but
who
runs
that
server
right
and
that's
the
whole
point
of
doing
Bitcoin
like
that,
it's
the
whole
point
of
doing
some
of
these
other
networks
as
well.
Where
you
tease
this
apart,
you
still
want
to
governance
models
terms.
This
is
what's
different
with
many
of
the
major,
because.
A
B
But
we
need
a
different
word
for
trust.
That
is
not
optional
right,
like
there's
a
difference,
I
think
between
trusting
parties,
because
you
can
and
you
have
a
reasonable
choice
and
trusting
parties
because
you
have
to
and
I
don't
know
if
anyone
follows
the
Edelman
Trust
Survey.
Okay,
this
is
a
trust
survey.
B
A
B
So
system,
so
food
trust
network
has
about
70
different
companies
that
have
been
brought
into
the
system.
Some
of
them
are
anchors
that
you
know,
like
Walmart,
there's
a
couple
of
other
big
brands
that
I,
don't
think
have
been
announced
yet
so
I
don't
want
to
give
away
anything,
but
it's
a
lot
of
Tier
one
suppliers
and
the
first
kind
of
killer
app
for
it,
as
so
far
has
been
traceability
of
leafy
green
vegetables.
In
fact,
it
sounds
like
Walmart
has
come
it
as
asked
their
Tier
one
suppliers
to
commit
it's.
C
B
Before
the
end
of
the
year
right-
and
this
is
a
shot
at
being
able
to
answer
that
question
when
e.coli
shows
up
in
a
supermarket
somewhere,
how
do
you
avoid
having
to
ban
all
leafy
greens
from
California
for
the
season,
which
is
the
response
that
you
get
now,
which
is
billions
of
dollars
with
the
product
thrown
away
and
and
and
so
that?
The
way
that
that
goes
is
they
said,
IBM
said
well,
here's
what
we
think
should
be
built.
B
Let's
start
talking
to
our
customers
that
are
in
that
space,
get
them
to
talk
with
you
with
themselves
and
with
us
as
a
consortium,
let's
figure
out
some
early
use
cases.
Let's
run
some
pilots.
Those
pilots
turned
out
well.
In
some
cases,
IBM
would
run
the
nodes
on
that
network
for
you
in
their
cloud.
In
other
cases,
they
say
you
know
if
you're,
Walmart
and
you're
able
to
run
these
systems,
you
probably
want
to
be
able
to
run
them.
You
can
run
them
on
Prem.
B
You
could
run
it
in
your
choice
of
other
cloud
provider
and
so
that
network
grows
and
and
with
all
of
these
things
you
know
at
some
point
they
bootstrap
right
with
is
say,
you
know
three
nodes
or
four
nodes
you
want
to
get
going
by
the
the
long-term
goal,
for
these
is
that
they
are
multilateral
in
every
way.
Right.
So
how's
done
multiple
clouds
serviced
by
multiple
IT
providers,
just
enough
to
give
the
participants
in
that
blockchain
a
sense
of
control
and
sovereignty
over
their
node.
So
they
know
what's
true
and
what's
not
right.
A
B
So,
there's
over
a
hundred
that
we
know
of
production
networks
out
there
now
like
food
trust
network,
not
all
of
them
have
achieved
that
degree
of
adoption
just
yet,
but
that
isn't
production
in
there
and
there's
others
all
over
the
world.
There's
a
production
network
in
China
of
banks,
doing
trade
finance
between
them
that
do
about
a
hundred
and
fifty
million
dollars
a
day
u.s.
dollars
a
day,
any
letters
of
credit
which
is
a
tiny
part
of
the
entire
trade
finance
market.
B
But
it's
it's
enough
to
like
cause
people
to
take
it
seriously
and
go
there's
something
here.
There
are
traceability,
networks,
they're
out
there
in
diamonds
in
rice,
in
electronics,
in
rare
earth,
metals-
and
you
know
a
lot
of
this-
still
has
to
be
proven
use
case
by
use
case,
because
some
markets,
you
know,
are
happy
to
trust
a
central
provider
or
they've
set
up
somebody
to
run
that
central
server
as
a
co-op
right
in
equities
markets.
B
You
have
a
company
like
DTCC,
who
is
extremely
well
trusted
by
the
trading
community,
and
even
they
realize
to
stay
ahead
of
the
market.
They
need
to
themselves
be
experimenting
with
blockchain
technology,
so
it's
it's
something
I
think
will
will
spread
across
a
but
you're
right
each
of
these
networks
as
a
bootstrapping
challenge.
So
so.
A
If
you
want
to
abstract
away
from
all
of
these
examples
that
you
haven't
cited
them
all,
of
course,
but
you
know
if
them
all
what
are
the
key
features
if
I
was
thinking
about
starting
building
such
a
network
for
something
that
I'm
trading,
what
are
the
essential
features
that
say?
Okay,
this
is
locked
in
as
a
solution.
I
should
look
at
very
seriously
right.
B
I,
where
you
have
this
kind
of
diversity,
custom,
and
you
want
to
support
that
diversity,
because
it
gives
everyone
optionality
top
to
bottom.
It's
it's
where
you
have.
You
know
a
reasonably
a
high
level
of
IT
competency
already
out
there,
at
least
in
a
critical
mass
of
organization,
so
in
healthcare,
for
example,
they've
picked
up
this
technology,
not
as
many
have
operationalized
it,
but
there's
a
few
like
change
healthcare
that
has
a
health
insurance
claims,
routing
platform,
doing
50
million
transactions
a
day
now
on
it.
B
So
I
needs
to
be
companies
who
right
now
are
still
willing
to
take
a
bit
of
a
risk
willing
to
spend
some
IT
dollars,
understanding
how
the
technology
works,
participating
in
pilots
realizing.
That's
the
only
way
to
really
know
what's,
gonna
be
appropriate
or
not
is
to
get
your
hands
dirty
with
the
code.
So.
A
Prepare
your
questions.
I
have
one
last
question
for
Brian,
because
when
I
started,
this
conversation
with
you
I
was
I,
have
to
confess
a
little
unsure
of
where
all
of
this
would
go
and
I
was
leaning
towards.
This
is
more
of
an
infrastructural
technology.
Where
yeah
will
these
some
level
of
transaction
processing
will
bring
in
more
trust
into
the
system,
but
the
more
I
talk
to
you
I
walked
out
with
exactly
the
opposite
sort
of
impression,
which
is.
This
is
a
fundamentally
transformative
technology.
A
B
B
You
know
that
having
to
trust
central
entities
makes
for
inefficient
markets
right.
So
for
me,
if
we
can
make
the
world
more
auditable,
if
we
can
make
it
harder
to
be
a
bad
actor
out
there,
not
that
I'm,
a
law
enforcement
rah-rah
kind
of
guy,
but
that
I'm,
you
know
when
we
when
we
build
markets
together,
we
there
are
rules
that
make
it
more
efficient
for
all
of
us
to
be
able
to
do
that,
rules
that
avoid
the
need
for
us
to
have
to
invest
a
lot
in
me.
B
A
C
In
order
for
a
blockchain
to
be
successful,
what
needs
to
be
adopted
by
many
parties
across
the
industry
right
potentially
including
a
competitor?
So
what
are
some
of
the
business
incentives
that
you
see
that
enables
companies
to
start
a
pilot
that
can
potentially
be
leveraged
by
its
competitors?
It's.
B
Usually
easiest
when
you
can
talk
to
any
of
the
existing
consortium
industry
right,
so
the
airline
industry,
a
good
party
to
talk
to
is
AI
Atta
right
in
the
telco
industry,
a
good
party
to
talk
to
as
the
ITU
or
to
go
to
Mobile,
World,
Congress
and
talk
to
I
mean
there's,
there's
consortium
all
over
the
place
in
every
sector
and
there's
some
new
ones
that
get
started
as
well,
like
the
mobi
Alliance
in
the
automotive
and
mobility
space
and
these
organizations.
Just
almost
like
a
mirror
image
of
us
yeah
the
softer
level.
B
Their
job
is
to
go
out
and
figure
out
at
a
sector
specific
level.
What
are
the
use
cases
that
reflect
needs
across
the
industry,
for
everybody
to
level
up
I
use
cases
that
you
know
reward
people
with
a
lot
of
assets
to
bring
in,
but
also
I,
have
the
door
open
to
startups
and
that
sort
of
thing.
So
it
can
be
hard
to
figure
out
how
to
bootstrap
these
things.
B
But
generally
you
can
find
intrinsic
interests
on
enough
parties
to
get
get
the
ball
rolling
and
then
all
you
need
is
those
early
adopters
to
prove
just
enough
value
that
you
start
bringing
in
the
mid
stage
adopters
and
then
the
the
late
adopters
come
in
because
they
have
to
because
they
can't
do
business
with
anyone
else.
Unless
they're
on
well.
