From YouTube: Where Blockchain Fits Into Enterprise Development - Hyperledger Fabric KC User Group, Dec 2019
Description
Recording from the December 2019 Hyperledger Kansas City blockchain user group meeting. Topic: Accessing and Implementing Distributed Apps (DApps) with Hyperledger Fabric.
Speaker David Pitt discusses where he feels blockchain fits into modern business applications and how they can be architected. He introduces Hyperledger Fabric, a permissioned blockchain framework, and shows how it can be used to benefit enterprise due to its tamper-proof and distributed nature. In this talk, David also introduces an open-source reference blockchain with a real use case applicable to global data.
This talk can be split into two parts - part one being the presentation and reference blockchain overview, part two being Q&A with user group attendees to ensure understanding of the presented concepts.

Conclusion
A
This,
our
fourth
beat
up
beating
on
fabric,
talk
a
little
bit
about
our
experience
with
it.
We,
you
know
we
do
a
lot
of
software
development
for
out
enterprises
in
the
area
a
couple
of
years
ago,
or
so
we
got
our
head
around.
I'll
start
investigating
block
tape,
technology,
not
necessarily
crazy,
but
the
blockchain
effects,
because
waves.
B
A
It
and
later
outfit
that
led
us
to
hyper
ledger
fabric
we
like
because
it
the
store
collected
because
IBM
we've
been
working,
I've
iam
in
the
past
they
get
a
price
IT
firms
so
that
let
us
that
direction.
We
like
the
fact
that
it
was
a
framework
as
opposed
to
a
ready-made
solution
or
platform
like
a
theory
on.
A
That
are
interested
in
through
the
concepts
you
know
kind
of
exploring
technology.
So
there's
a
training
talked
about
it,
the
use
cases
for
it
better.
Nothing
full
bore
into
forgot
your
many
types
of
other
than
our
we
deploy
that
on.
You
know,
cloud
time
comes
that
you
know
somebody
needs
some.
Some
hardcore
assistance
in
deploying
Network
and
moving
parts
estimate
what
a
knowledge
base
in.
That's
that's
really
work.
Why
how
we
got
in
touch
with
hyper
liquor
looks
foundation.
We
also
have
a
framework
in
there.
We
have
seen
this
plug.
A
We
got
an
open
source
tool
called
Byzantine
config,
which
is
a
tool
for
fabric
on
how
there's
a
lot
of
administration
involved.
Managing
certificates,
update
transactions,
familial
fabric.
You
know
to
update
it.
You
have
to
execute
a
updates
and
transaction
update,
integrates
my
blog
King,
so
we
build.
B
A
B
B
B
B
A
It
than
just
that
right,
these
transactions
are
all
gonna
be
flowing
through
and
out
there
available,
query
or
updated
or
execution,
or
what
admin
how
they
can
be
integrated
into
into
an
application
right.
That's
kind
of
want
to
talk
about
that.
Our
thoughts
on
it.
That
would
be
very
detailed.
It's
got
a
high
level.
We
could
have
a
discussion
if
you
guys
have
any
experience
with
a
chimed
in
just
go
through
that.
So
I
was
good.
That's
my
call.
A
Some
kind
of
relational
data
sources,
one
big
giant,
single
source
of
truth,
they're,
all
there
confines
and
they
have
and
many
many
applications
will
be
accessing.
That's
right.
So
we
will
have
a
single
source
of
truth
could
be
on
the
mainframe
home
for
school
could
be
more
modern,
db2
sequel
server,
you
name
it
Enterprise.
B
A
A
That's
changing
a
little
bit,
you
know,
interestingly
enough,
the
distributed
type
of
programming
is
we're.
Finding
is
where
companies
are
starting
to
break
up
that
single
source
of
truth
in
their
walls.
That
would
lead
us
to
micro,
service
type
architectures
that
we
were
seeing
traditionally,
we
monolithic
applications
have
to
talk
to
the
single
source
of
truth
and
perform
some
kind
of
operations
on
it,
maybe
multiple
applications,
monolithic
applications
or
to
it.
A
The
latest
trend
is
in
breaking
that
up
into
more
of
a
micro
service,
aka
distributed
platform,
we're
lots
of
smaller
great
services
are
talking
to
it
for
that
to
work,
they're
breaking
up
that
signal,
source
of
truth
into
distributed
databases
right
within
the
confines
of
the
world.
That's
that's
another
topic
talk
about
it,
but
it
is
relevant
to
watching
because
the
idea
behind
watching
that's
distributed
also
and
it's
a
single
source
of
truth,
that
is
on
the
side
of
an
organization
walls
right.
A
So
you
can
think
of
a
blockchain
as
a
enforceable,
trustworthy,
omnipotent
data
store
and
a
single
source
of
truth.
That's
outside
your
position,
which
I
think
is
still
maintaining
its
across
organizational
boundaries,
so
sharing
an
integration.
So
the
student
sort
of
the
truth
of
presiding
in
two
different
organizations.
I
have
a
little
example
here,
where
API
is
EDI
so
on
and
so
forth,
are
all
used
to
share
information,
see
this
single
surfer
truth
data
is
copied
to
another
organization's
boundaries,
that's
their
single
source
of
truth.
Now,
so
it's
Kaakha,
Kaakha
Kaakha!
A
I,
don't
know
how
accurate
it
is,
but
it's
a
patient.
Imagine
a
hospital
or
healthcare
organization
that
has
piece
of
information.
Building
information
visits
like
that.
There's
going
to
be
a
single
source
of
truth
with
this
somehow
maybe
not
be
this
design,
but
labs
that
typically
most
hospitals,
Moulton
won't
perform
their
own
labs
they'll,
send
it
off
to
quest
or
some
other
diagnostic
center
right.
So
that
means
that
that
if
the
sample
is
set
over
them,
they
can
perform
the
work
my
blog
did.
A
The
lab
is
somehow
that
information
is
brought
to
the
hospital
old
days.
It
was
keyed
in
right.
You
have
some
kind
of
EDI,
so
kind
of
API,
some
kind
of
file
download
some
kind
of
file
transfer.
It's
doing
it.
Well,
that
happens.
We've
just
duplicated
this
database
structure,
the
organization
that
wants
to
consume
it
can
get
it,
but
every
organization,
assuming
it's
gonna,
put
it
to
their
single
source
of
truth.
However,
they
want
to
do
it.
So
that's
how
kind
of
a
time
in
nowadays
this.
A
Fitting
it's
a
data
sharing
right.
This
is
a
use
case
that
we
see
a
lot
of
upside
with,
believe
it,
because
we
do
a
lot
of
work
in
this
treating
slide
right.
We
have
over
the
years
integration.
You
know
moving
data
between
organizations
and
entities.
This
is
where
I
get
excited
from
being
an
architect
that
we
had
a
blockchain
implementation.
A
We
have
a
single
source
of
truth
here
across
the
organization
batteries
right,
the
labs,
the
Diagnostic
Center,
our
Hospital,
the
core
entities
participating
on
this
bachi
participated
in
it.
Then
everybody
wants
to
confirm
the
truth,
as
labs
or
performed
in
near-real-time
fashion.
They'd
be
available.
Everything
at
everybody
else's
the
epoxy
technology.
Blockchain
technology
would
make
trustworthy
permission
when
of
course,
in
this
case,
this
is
where,
as
subtle.
A
It's
pretty
powerful
concept,
because
the
conjecture
is
that
if
this
network
was
robust
enough,
then
those
participants
in
it,
the
IT
cost-
would
be
lower
the
Diagnostic
Center
may
not.
They
have
to
stand
up
tons
of
servers,
shorted
databases,
failover
blah
blah,
keep
that
up
a
lifestyle
but
24,
there's
still
sort
of
soft
right.
They
have
to
maintain
button
that
works
big
enough
collaboratively.
A
A
It'll
be
available
to
everybody
that
will
be
the
source
source.
True
across
that's
that's
kind
of
where
we
get
excited
by
the
type
of
data
that's
going
to
go
in
here.
Is
it's
going
to
be
unlikely
that
an
organization
is
going
to
put
their
entire
database
in
the
blockchain?
We're
talking
about
the
global.
B
A
B
A
See
much
of
a
technology
eliminating
db2,
Oracle
or
any
traditional
database
model.
We
see
it
fitting
into
it
right
and
it's
really
just
a
tournament
way
to
share
data.
We're
placing
the
EDI
is
placing
the
ETL
file
downloads,
or
things
like
that
right
now,
there's
a
lot
of
other
core
cases
with
that
performance
in
that
book
separately,
that
that
sharing
of
data
you
know
through
any
kind
of
organizations,
workflow
it's
powerful
right
now.
A
What
I
read
about
is
supply
chain
right,
because
that
makes
a
lot
of
sense
because
there's
a
lot
of
parties
involved,
you
know,
and
what
they're
finding
is
just
by
sharing
data.
By
saying
it's
going
in
from
you
know,
they
have
some
device
that
takes
something
off
of
them:
cargo
ship
into
a
warehouse
on
to
a
train
always
up.
A
They
can
track
that
the
whole
way
through
this
shared
technology
blocking
technology
they
eliminate
costs,
because
what
they're
finding
is
less
Mesquite
in
by
hand
typically
doesn't
warehouse
with
whatever
standed
mistakes
happen,
so
just
by
deploying
blockchain
framework
them.
The
folks
that
have
done
supply
chain
have
to
tell
you,
they're
saving
money
and
sitting
on
technology
stack
or
more
on
lesson
errors
right,
no
errors,
because
it's
going
all
the
way
through
it
or
not.
Go
under
this
vendor.
That's
well.
We
don't
have
it.
B
A
That's
the
early
outcome
of
some
of
the
supply
chain
use
cases
that
folks
is
seeing
so
where
we
see
the
blocks
even
into
the
enterprise
down
talked
about
this
before
this
is
easy
on
picture
is
an
easy
and
concept
detector.
The
technologies
there
I
mean
blockchain
data
structure,
the
peer-to-peer
gossiping
all
that
stuff
is
proven
network.
So
it's
great
it's
getting
a
bit
boring
to
be
more
human
problem
or
an
organization
problem
or
user
problem
than
the
technology
problem
technologies.
A
Here,
I
think
it's
time
is
now
but
trying
to
go
and
get
everybody
involved
and
everybody
using
it.
That's
that's
difficult.
Go
yeah!
It's
the
access
time
like
doing
a
C
will
select
versus
going
to.
Well,
that's
a
really
good
question.
It's
going
to
be
probably
slower,
I
would
think,
and
so
it's
going
to
be
I
work
near
real-time,
not
real-time,
and
so
that's
gonna.
Also,
let
me
you
know
a
supply
chain
or
a
lab
result
doesn't
have
to
be
real-time,
a
training
platform,
probably
not
a
good
idea.
A
Right,
I
mean
I,
don't
know
if
that's
gonna
work
this
latency
involved.
This
is
a
this
is
what
you
call
the
visual
consistency,
type
of
architecture
to
where
the
network
is
going
to
basically
reach
consensus
transactions
and
blocks
going
to
go
through
eventually,
so
you
are
gonna
have
to
probably
apply
this
to
eventual
consistent,
see,
type
use
cases
as
opposed
to
real-time
stock
trading
platform.
I
wouldn't
know
it's
against
now.
To
get
that
to
your
point,
that's
a
good
question.
So
I
would
agree.
A
The
custom
variety
may
be
out
there,
or
maybe
some
kind
of
universal
identify
or
some
sort
right.
I
they're
still
gonna,
be
this
compromise,
our
architecture
or
some
online
processing
or
metrics,
and
things
like
that.
It
may
have
to
copy
that
data
right
into
traditional
data.
Warehousing
type
things
so
in
certain
cases
brought
up
is
valid.
You
know
you
may
have
to
say
you
know
what
for
reporting
purposes
and
things
like
that
we
may
need
to
make
a
copy
of
that.
A
A
A
B
A
Do
you
have
to
go
from
block
one
all
the
way
off
the
block?
2
million?
Now?
Do
you
know
which
block
it's
India
thanks?
You?
Yes,
so
in
fabric
there's
a
its
front
end
with
the
couchdb
nice
thing
about
fabric
that
for
perform.
For
that
reason
there,
if
you
don't
query
it
locks
door,
locks
bidding
is
the
blockchain
is
stored
in
the
blockchain
on
a
file
of
myself
appeared.
Oh
right,
I'm
getting
technical
here,
but
fabric
has
a
fronting
caste,
be
my
default.
B
A
Maintains
the
latest
information
per
transaction
now
my
block
you'll
need
it
my
block,
but
if
remember
pend
only
ledger
so
if
I
have
some
kind
of
identifying
key
which
I
have
to
have
and
have
information
that
I'm
you
take
that
you
take
that
you
take
that
the
history
is,
could
be
relevant
really
what
we
care
about.
Typically,
it's
the
latest
greatest
that's
going
to
be
in
a
every
in
a
high-performance,
CouchDB
database,
query,
complex
queries
and
or
boolean
logic.
All
kinds
of
stuff
meet
your
needs
and
that's
that's
part
of
our.
A
Why
I,
wouldn't
I
wouldn't
put
the
customer
information
watching
hi
so
in
this
diagram?
Oh,
this
is
their
stuff.
The
only
thing
I'm
putting
in
the
blockchain
is
a
lattice
message,
just
a
labs
source.
So
the
information
that
everybody
cares
about
those
in
watching
customer
information.
Billing
information
is,
as
usual,
I.
Don't
change
anything
there.
Db2
whatever
you're
using
now,
there's
does
only
global
information.
That's
watching
so
I!
A
Don't
we
don't
recommend
putting
everything
into
boxing
for
the
reason
you're
pointing
out
right,
I
mean
that
I
mean
plus
it's
different
to
everybody,
because
my
customer
information
and
numbers
of
schemes
and
rates
a
lot.
That's
a
totally
different
thing.
Organic,
but
information
that
we
should
care
about
is
lab
mix.
That's
common!
All
else
could
be
the
hospital.
If
you
can
see
see
it
could
be
practitioner,
it
could
be.
You
know,
whoever
a
person.
That's
in
the
block,
that's
what's
sharing
distributed.
Everything
else
is
business
usual.
A
A
A
I
think
your
questions
valid,
but
the
key
is,
you
know,
there's
gonna
be
overhead
here,
that's
just
going
to
be,
hopefully
I
wouldn't
think
I,
wouldn't
if
I
was
going
to
design
their
stock.
Saying
I
don't
want
a
lot
of
data
I'm
on
the
minimum,
that's
global
to
everybody
else,
and
that
makes
some
identifiers
in
there
that
we
all
agree
upon
or
you
can
use.
That's
that's
the
hard
part
that
that
modeling
of
what
we
put
in
there,
but
don't
put
your
old
database
on
that.
You
know
just
not
get
it
before
now.
A
A
That's
all
right:
we
never
have
the
same
thing
to
do
this.
What
more
does
it
because
they
have
a
hammer?
They
say.
Oh,
you
want
some
lettuce
to
us
you're
using
our
blockchain.
That's
one
way
to
okay.
Okay,
be
able
to
you,
know,
don't
participate,
so
some
some
places
can
do
that.
Other
ones
are
gonna,
be
too
competitive.
Right,
I
mean
who's
good
and
you
brought
up
who
owns
it?
Who
does
it
well?
I,
don't
know
I
mean
that's
the
thing
it's
gonna
have
to
be
some
kind
of
steward
of
this.
A
The
association's
could
have
to
say.
Okay,
we've
got
to
stand
these
nodes
up.
Okay,
we
got
up
when
we
make
a
transaction.
We
gotta
call
the
node
who
owns
it.
Who
sets
it
up?
That's
that's!
Maybe
someday
we'll
be
able
to
help
out.
That's
got
to
be
identified
right,
I
know,
there's
some
companies
out
there
that
do
it
for
you,
custodians
of
the
blockchain
right,
but
that's
got
to
be
established
by
the
solution.
Yeah,
that's
that's
an
organization!
That's
technology!
We
have
a
blockchain
network,
that's
super
resilient.
A
We
got
nodes
I'm
sure
we
got
a
node
in
ec2.
We
got
a
couple
orders,
you
know
consent
all.
So
it's
not
going
down
and
it
will
work
well,
but
somebody
that's
gonna
cost.
It
cost
us
to
put
it
out
there
and
it
costs
us
to
maintain
it's
not
free
right,
and
so
it's
just
permission.
I've
got
to
manage
certificates,
I
gotta,
say
who's.
Gonna
has
access
and
doesn't
have
that
so
somebody's
gotta
fill
in
that
void
and
that's
what
you
gonna
see
companies
like
IBM
doing.
Maybe
us
others
right
now.
A
You
could
do
that
or
some
consortiums
gonna
say:
ok,
here's
the
money
for
our
blockchain
initiative,
because
it's
blockchain
is
gonna,
save
us
some
money
as
a
whole.
You
know
so,
let's
Tony
up
some
money.
Let's
get
this
going.
Let's
get
somebody
can
come
in
and
set
up
our
network
and
it
will
all
use
it
and
be
happy
together.
All
those
politics,
that's
how
I
see
it
coming
and
that's
why
I
think
some
people
that
are
predicting
blockchains
to
take
a
couple
years
before
to
go
now
killer,
app
that
you
used
right
away.
A
A
B
A
A
company
up
there,
that
is,
that
idea,
it's
a
company,
it's
a
steward
for
it
and
they
and
they
are
running
a
countrywide,
canada-wide
truck
transportation
and
maybe
the
Canadian
government
somehow
supporting
this
with
12
notes.
So
we
got
12
bureaus
up
a
couple,
so
they
they
have
indicated
that
doesn't
take
a
ton
of
computing
infrastructure
support.
That's
an
entire
block
chain
supply
chain
right,
so
it
is
very
cheap
and
do
your
experiment
of
your
idea.
A
It's
one
API
into
the
boxing
you've
got
about
children.
That's
it!
It's
not!
Everybody
have
a
set
their
own
database
up,
sucking
down
their
own
calling
one
API
replicates
out
with
our
fastest
hole.
It
adds
up.
So
that's
the
article!
So
that's
where
fits
in
500
Buffy
recap
so
carve
off
fabric
how
it
works
really
briefly
here,
because
I
talked
to
a
long
time
on
it.
It's
a
beautiful
tribute
and
only
ledger.
We
all
know
that
the
consensus
out
that
box
is
Kafka
voting
based
it's
Byzantine
fault-tolerant,
but
it's
not
visit
team
consensus.
A
So
hearing
force,
identity
and
trust,
as
we
know,
fabric
is
a
permission,
meaning
everybody
that
have
an
identity,
have
a
certificate
to
access,
open,
public
type
of
blockchain,
I.
Think
in
theory,
I'm
a
base
material,
it's
both
and
then
the
logic
smart
contract
is
also
just
different.
So
the
nice
thing
about
you
know:
smart
contract
change
code
is
one
of
the
same.
Smart
contract
is,
you
know,
I,
think
of
it
as
fabric
also
kinko
code,
but
basically
it's
distributed.
B
Logical,
you
can,
you
know
the
fabric
watching,
isn't
that
single-purpose
debit/credit
cryptocurrency
data
store
it's
whatever
you
want
it
to
be
it's
whatever.
You
want
to
store
out
there.
Besides
the
data,
that's
putting
it
out
there,
you
can
apply
a
fixed
line,
business
logic,
whatever
you
want
and
we
call
a
chain
code.
B
That's
also
important
watching
it's
executed
based
on
parameters
right,
so
you
think
of
it
a
stored
procedure
or
whatever
you
want,
but
in
many
cases
in
many
cases
the
big
of
just
putting
information
into
the
blockchain,
but
sometimes
based
upon
who
you
are
other
parameters.
You'll
want
to
share
logic
fabric
has
a
allows
you
to
use
non-deterministic
logic
such
as
languages
such
as
Java
JavaScript
bill
he's
a
non-attorney
non-deterministic
languages.
B
It's
because
they're
endorsing
mechanism
they
set
up
endorsers,
they
compare
contrast,
gets
a
digital
science
results
to
compare
up
for
a
validity
right.
So
that
way,
something
to
fear
IAM
has
it
to
pass
users
on
solidity
language,
because
it's
deterministic
they
take
away
all
their
random
number
generators
anything.
So
when
you
execute
a
function
and
solidity,
you
can
guarantee
it's
going
to
always
be
that
result
wherever
it's
executed
and
that's
why
they
had
to
rip
out
all
the
other
JavaScript
stuff.
This
deterministic
right.
B
They
have
a
non-deterministic
language,
so
we
can
use
terminus
declined,
which
is
because
it's
endorsing
mechanism
evaporating.
That's
do
you
think
they
can
read
from
the
latest
state
of
the
blockchain.
What
it's
gonna
write
its
execution,
that
payload
is
comparing
the
signed
and
compared
to
make
sure
that
there's
no
deterministic,
lock
Taj
akin
there
and
there's
a
bath
result.
B
So
there's
there
is
a
performance
factor
in
fabric,
smart
code
mechanism,
right
I,
think
that
would
be,
but
I
don't
have
to.
If
I
have
a
giant
network
I
don't
have
to
run
that's
more
contrast
in
every
new,
probably
running,
on
the
endorsing
nodes
which
are
configurable,
pretty
good
performance
and
it's
distributed
right.
So
this
is
the
picture.
That's
the
topology
processing
this.
B
You
know
we
have
peer
nodes
that
order
this
is
one
I
probably
got
you
know
so
I
have
the
order
is
the
mechanism
that
is
taking
the
blocks
and
seven
dating
the
updates
of
new
blocks.
You
know
block
cutting
cut
the
block
through
the
gospel
structure
since
it
out.
There
knows
the
gospel
structure.
Is
you
know
more
technical
we've
talked
about
today,
but
just
know
it
works
like
any
other
distributed,
it's
going
to
go
ahead
in,
you
can
communicate
what's
going
on
and
it
just
propagates
through
the
network
right
the
blocks
of
copy.
B
If
I
were
to
stand
up
a
peer
node
like
any
block
treat
implementation
I
would
if
I
was,
if
I
had
it
the
right
digital
certificate
I
could
do.
It
would
talk
to
the
order
and
the
order
would
give
me
all
the
blocks
and
I
have
a
block
come
down.
Every
node,
as
the
full
block
store
like
I
said
earlier,
is
front
of
my
CouchDB.
Every
node
has
a
couchdb
I
think
of
as
a
cache
I.
Guess
the
big
good
way
to
do
it.
B
This
is
what
we're
going
to
talk
about
today,
the
node
they
have
SDKs
for
node
go
and
go
to
these
SDKs.
What
we're
talking
about
earlier!
So
this
is
the
blockchain
running
out
there.
These
labs,
so
if
you
might
want
to
interact
with
it
and
they're
from
their
enterprises,
would
stand
up.
One
of
these
SDKs
language
of
their
choice
and
it's
gonna-
have
a
and
know
how
to
do
the
certificate,
so
they
connect
to
the
pier
know
whatever
they
want
to
query
or
execute,
do
whatever
they
interact
with
the
with
the
blockchain
right.
B
A
Credentials
and
then
I
could
go
ahead
and
see,
orders
and
stuff
coming
in.
You
know
Bill
of
Lading
or
material
whatever.
How
about
that?
We
lucky
that
what
we're
talking
about
this
kind
of
the
SDK
and
I
can
talk
to
it.
I
think
that's!
Cheaper
than
standing
up
databases
of
code
call
an
API
bringing
it
down
integrating
it.
Instead,
I'm
just
gonna,
say
audience:
TK!
Here's
your
contract,
man
call
him
do
stuff
with
guys.
I've
have
a
server
right,
I'm,
not
saying
it's
not
there,
but
I
have
to
have
a
little
less
work.
A
Plus
I
can
rely
on
that
information
interact
with
then
I
would
interact
that
I
get
that
information,
that's
Dylan!
It
would
still
work
with
my
line
of
business
right.
So
that's!
This
is
what
this
is
the
client
access
mechanism
to
get
us
down
here,
but
you
can
use,
go
or
Java.
It
could
be.
C-Sharp
I,
don't
know,
but
I
don't
see
the
reason
why
not
because
this
is
just
G
RPC
right.
So
the
other
thing
I
like
about
fabric
is
all
this.
Communication
is
going
using
protocol
buffer
technically
with
G
RPC
is
Google.
A
It's
Google's
RPC
and
it's
very,
very,
very
performant.
We've
done
some
tests.
It's
smoke
standard,
HTTP,
JSON,
serialization,
lock
has
stuff
that
we
do
it's
very
fast,
very,
very
fastness.
It's
a
protocol
buffer,
so
they're
they're,
basically
sort
of
explained,
but
it's
a
it's
a
information
to
come
across
as
a
structured
buffer,
and
so
they
get
some
super
format.
So
in
John
to
your
question,
your
FEC
gives
you
a
little
bit
of
a
hit
a
little
faster
hit
than
just
standard
HTTP,
using
sterilize
and
JSON,
or
whatever
you're
going
across
the
three
day
fast.
B
We're
going
to
add
it
to
the
chain,
and
what
is
your?
What's
your
confirmation
I
think
that's
going
to
be
I,
don't
want
any
numbers
on
that
I
mean
it
depends
on
how
many
orders
and
how
many
nodes
are
in
your
network.
Right
I
mean
so
it's
good
in
a
number
of
the
number
of
confirmations
is
configurable.
B
So
this
is
a
framework,
so
I
don't
have
a
hard
number
on
that,
but
it's
going
to
be
if
I
have
I'm
already
to
have
at
least
two
endorsing
nodes
for
sickness
and
at
least
two
Kafka
instances
for
not
scalability,
but
for
performance
right,
kitchen
ones
down
or
after
I
can
look
balance
between
them.
If
I'm
going
to
go
from
my
gut.
A
B
We're
recommending,
while
you
can
configure
the
block
sides
and
that's
another
good
question
right,
because
you
know
you
can
tune
the
block
size
for
that.
So
there's
all
these
tuning
things
so
I
just
don't
know.
If
I
can
you
know
with
Bitcoin,
you
have
a
live
production
system
with
lots
of
note.
Actual
transactions
happening
right
now,
so
they
can
give
you
a
consensus.
You
know
ten
minutes
whatever
I
need.
I
can
tell
you
it's
going
to
be
good
or
the
dead
minutes.
I'll
guarantee
that
you
know
you
know
reach
consensus.
B
Yeah
I
mean
you
met
Google
and
you,
google
fabric
transaction
time,
there's
production
fabrics,
I'll
tell
you
I,
think
I
really
know
I
mean
and
there's
ways
of
scaling.
I
mean
watch
size
number
of
nodes
in
a
number
of
order.
If
you
set
up
so
that's
built
to
be
and
then
using
G
RPC
was
a
pretty
dang
fast
wire
to
wire
type
communication.
It
didn't
get
much
faster,
we're
all
IP,
but
that's
some
structure,
so
I,
don't
think
I
also
think
the
cash
upfront
and
it
blocks.
B
You
know-
and
this
would
lead
to
the
next
question-
everybody
always
has
and
I
don't
have
a
great
answer
for
it.
There
are
ways
and
fabric
to
delete
and
clone
and
prove
your
stuff,
because
you
have
a
giant
watching
them.
Working
every
has
a
copy
of
it
right.
It's
gonna
grow
forever
right.
Well,
my
answer,
which
is
kind
of
glib
is
that
is
that
first
up
we're
to
really
promote
not
giant
normalized
structures
and
applause.
We
want
to
promote
pretty
flat
transactions.
I
hope,
that's
what
I
would
encourage
very
information.
B
That's
not
you
know,
then
have
a
relationships
and
normalized
I
wouldn't
recommend
that
so
it's
gonna
be
tight,
quick
information,
that's
going
to
be
super
speedy
and
snap
right
through
the
network.
As
that
grows
with
fabric
you
can
you
can
cut
blocks
and
make
things
back
it
up,
whack
it
so
insurance
right,
you
don't
need
there.
You
can
do
that,
but
that's
there's
not
a
real
thinking.
It
is
gonna.
It
is
gonna.
You
have
to
pay
attention
to,
because
if
you
get
a
lot
of
adoption
transactions
through
the
day
wants
to
grow.
B
Fine
access-
that's
talked
about
us.
This
is
a
more
detailed
picture
of
it.
They
can
register
to
roles
appear.
So
here's
a
here's,
here's
kind
of
an
example,
our
micro
service
architecture,
very,
very
high
level.
I've
got
my
react.
Ui
or
any
UI.
Angular
react.
Node
pair
mobile,
app
tablet.
Who
cares
here
talking
to
some
kind
of
API
server?
B
That's
serving
them
for
an
application
will
stay
for
a
gateway,
Mule
soft
or
something
like
that
in
an
enterprise
in
that
that
API
gateway,
ass
or
some
sort
of
server
is
going
to
go
ahead
and
use
for
them
out
to
services
servicing
this
app.
That
could
be
service
here.
That
goes
to
a
traditional
database.
Whatever
you
go
into
customer
information
to
whatever
is
usual
or
a
piece
of
that
could
go
to
appear
notes.
This
information
for
this
services
is
getting
its
data
store
from
one
team
right.
B
You
know
this,
you
could
a
monolithic
implementation
would
have
everything
in
here
we're
recommending
a
more
of
a
micro
service,
but
where
this
is
just
aggregating,
the
API
calls
calling
out
to
different
services
and
do
different
things
and
then
probably
have
a
service.
That's
going
to
be
responsible
for
interacting
with
your
watching
that's
kind
of
how
we
would
architect
it
yeah,
very
high-level,
but
that's
how
we
would
engage
it
peer
noted
that
watching.
A
B
A
our
implementation
is
of
what
I
just
talked
about
you
can
get
to
it,
and
this
is
a
shameless
plug,
but
it's
open
sourced.
For
the
most
part
we
have
this
here's.
What
I
was
talking
about.
This
is
a
react
app
talking
to
an
epi
server
and
that
API
server
is
getting
these
lab
results.
This
is
what's
in
our
watching.
B
Imagine
these
are
flu
results
right,
so
kind
of
an
adder
result.
That's
the
data
we
have
in
there.
So
you
know
these
are
just
clue.
So
the
theory
here
is
is
if
people
participated
in
this,
it's
a
CDC
diagnostic
senators,
doctors,
offices,
hospitals.
When
any
somebody
got
flu
or
a
mobile,
app
I
got
the
flu.
I
could
say:
oh
I
got
the
flu
right.
I
could
call
this
API.
This
API
same
time,
call
from
a
mobile
app,
isn't
the
blockchain?
It's
calling
it's
calling
a
server.
B
We
have
up
in
the
cloud
that
API
cloud
is
server,
is
calling
to
watching
and
putting
in
their
lab
result
or
query
lab
results
to
get
it
back
and
then
the
other
information,
like
the
list
of
counties
and
other
information,
is
that
in
watching.
That's
just
in
our
normal
database,
okay,
so
this
is
an
example
of
integrating
with
these
lab
results
are
available
by
anybody
that
wants
the
Korea
blockchain
do
whatever
they
want
with
it
right.
So
imagine,
right
now,
I
know
that
I
believe
how
they
track
the
flu.
Is
they
good?
B
Google
search
is
a
new
kind
of
stuff
and
the
CDC
published
his
numbers
delayed
stuff
like
that.
Imagine
if
I
went
into
my
doctor's
office
and
said,
hey
swapping
my
thing
if
they
went
into
their
system
from
CERN
or
época,
wherever
they
used
and
added,
it
would
just
call
this
API
and
put
it
out
right.
They
have,
they
have
an
API
call,
they
would
say:
Oh,
we'll
keep
its
information
will
also
say:
beep,
it's
got
the
fluid.
B
What
type
is
it
his
age
goes
out
just
for
the
greater
good
the
CDC
can
pull
that
information
or
as
they
do
it.
If
it's
coming
from
a
permission
provider
like
the
flute
like
the
doctor's
office
or
hospital
or
state
human
health
resource,
for
whatever
their
permission
and
they're
doing
it,
you're
going
to
get
pretty
close
to
real-time.
B
Right,
instead
of
guessing
you
just
see
the
blue
come
across
right
as
it
happened
or
people
you
can
even
trust
you
so
you
know
think
it's
green
assault,
but
I
could
put
a
little
app
here
that
allows
this
number
just
one
chance.
Yes,
people
could
lie,
or
maybe
just
kind
of
maybe
an
app
that
encourages
somebody
that
fit
result.
So
maybe
they
get
something
for
so
they
can.
You
know,
encourage
them
to
use
it,
but
anyway
you
see
how
that
blockchain
did
well
as
opposed
to
the
CDC.
B
You
know
right
now
they
have,
they
have
his
information.
They
collected
to
get
it
recorded
by
all
the
they
have
to
key
it
in
or
the
calling
somehow
is
getting
copied
all
the
way
into
the
CDC
or
maybe,
as
this
form
that
makes
scanning
it.
It
would
have
to
do
that.
I
guess
hypothetical,
this
to
happen.
It
would
be
probably
difficult
organizational
lives,
but
technology
is
there.
It
would
not
take
a
lot
to
to
make
this.
You
know
so.
We've
got
to
maintain
and
feed
it,
but
it
would
technology
like
this
information
with
you.
B
You
know-
and
you
know,
theoretically,
maybe
it's
worth
investing-
it
was
to
put
the
savings.
Well,
the
quicker
we
know
about
the
blue
people
get
prepared.
The
overall
cost
of
society
goes
down
right.
People
are
safe
in
less
work
days,
so
right,
so
you
said
you
gotta
get
everyone
to
buy
into
this
yeah.
You
put
all
that
data
in
there
I
mean.
Is
that
gonna
be
much
different
than
you
know,
everybody
that
trying
to
convince
like
everyone
to
just
upload
that
to
Cerner's
information
or
whoever
is
currently
having
that?
B
Well,
if
you
could,
but
the
problem
is,
that
is
an
information
they
have
to
copy
it
around
right.
Now
they
can
just
participate
and
as
it
goes
there
it's
there,
but
it
would
be.
We
were
talking
about
this
earlier,
it'd
be
less
than
saying.
Okay,
you
need
to
go,
get
your
program
to
call
service
API
like
so
what
happens
is
if
service
says.
B
This
we're
sending
them
serve,
they
could
and
here's
our
greater
good
database
we've
got
a
database
here.
Sir,
is
now
set
up
a
bunch
of
load,
balancers.
Think
of
the
world
right.
The
end
of
the
world.
They're
gonna
have
to
invest
in
very
robust
structure,
more
so
than
just
marketing
Network
right.
It
set
that
all
up
right,
but
they
may
do,
and
they
say
we
got
the
box
a
lot
of
PR.
For
this.
Let
me
the
CDC
has
to
call
that
API
bring
data
down
and
every
other
organization
can
do
it
with
this.
B
It's
there
they
can
call
it.
They
can
still
look
at
that
information,
but
they
don't
have
the
a
fabulous
IT
right.
So,
yes,
they
could.
There
doesn't
prevent
even
technically
from
doing
any
that
kind
of
stuff
it's
just
in
plus.
There
still
could
be
errors,
we're
gonna
copy
down,
put
it
there
Dave.
We
can
do
something
with
it.
They
go.
What
happens
if
you
know
servers
not
up
or
they
got
a
trust
server.
Your
thing
is
to
trust
this
thing
here
with
this
is
what
cert,
or
maybe
trust,
Cerner
there's
a
snack
here
coming
in.
B
Are
they
putting
it
in
a
write
with
their
software?
Is
that
they're
giving
it
to
them
right?
They're?
Not
if
somebody
it's
the
CDC,
says
government
regulation,
here's
our
blockchain,
we
believe
in
watching
as
being
accurate,
added
there's
that
I
guess.
That's
those
same
concerns
about
that
act.
That
information
you
didn't
upload
it
into
the
blockchain
being
accurate
to
writing.
But
if
it's
an
immutable
London
with
that?
No,
what
would
you
do
with
inaccurate
information?
Well?
B
Well,
so
the
theory
would
be
the
CDC
or
the
government
says
ethics
Cerner
and
if
you
want
to
be
a
healthcare
provider
like
a
medical
records,
app
you're
going
to
go
ahead
and
you
know
put
this
information
in
the
watching.
So
here's
your
certificate,
here's,
your
here's,
your
note
and
if
they
would
have
to
be
trustworthy,
might
get
the
trust,
Cerner,
epic,
that
they're
going
to
go
ahead
and
in
their
software
when
you,
when
they
put
a
test,
result
thing
that
it's
going
to
go
ahead
and
make
that
call
you.
B
Yes,
you
can
trust
that
as
damn
guaranteed
as
then
nobody's
gonna
be
a
man
in
the
middle,
those
gonna
tamper
with
it.
But
if
the
technician
types
it
in
Iran,
but
you
can
trust
that
if
it's,
the
communication
from
Cerner
into
the
blockchain
is
tamper
bridge
right,
nobody,
the
tap
with
key
I,
mean
it's
impossible
attempted
with
that
mess
with
it
once
it's
in.
But
if
you
know
somebody
of
course,
the
result
that
you
can't
fix
that
and.
B
B
You
like
it's
coming,
so
what
they're
doing
in
these
things,
they're
not
just
having
each
one
type
into
their
system
that
goes
into
the
block
team,
because
it's
the
same
problem
they're,
enabling
Alti
devices
so
you're
going
scan
in
in
the
blockchain
it's
available
to
the
next
right.
That's
the
only
going
to
point
out
is
fabric
has
a
way
to
push
right,
so
so,
when
something's
added,
it
will
think
of
broadcast
right.
This
is
the
mechanism
and
I
T.
It
says,
oh,
my
one
thinks
of
this.
You
can
sense
when
things
are
added
to
it.
B
Tamper-Proof
database
right,
I,
think
so
you
could
use
existing
I
could
set
up
a
regular
database
to
do
the
same
thing
right,
but
watching
technology,
everybody
important
to
say,
I
I,
believe
that
it's
trustworthy
right,
if
they're
all
competitors
here
right
after
concern-
or
you
know,
that's
kind
of
it's
immutable,
so
we
can
say
that
maybe
more
the
lab
results
may
not
be.
Who
cares?
Who
wants
to
fake
that
right?
B
Listen
for
government
wants
to
mess
with
our
whatever,
but
in
a
supply
chain
where
vendors
and
competitors
are
in
there
maybe
say
yes,
so
so
John
came
up
and
scanned
that
carbonyl
of
lettuce-
and
it
was
they
went
from
here
to
here.
Well,
everybody
said:
that's
what
happened
got
to
pay
the
bill.
There's
no
mistake
right
or
you
know,
I,
that's.
Where
is
she
right?
So
you
could
still
do
that
with
existing
technology.
Watching
doesn't
change
that
really
the
thing,
but
the
thing
about
blockchain
that
is
solves
the
problem.
B
Is
the
peer-to-peer
distributed
nature
of
it
right?
It's
solved.
You
know
that
centralized
copying
out
it's
distributed
right,
the
way
it's
like
Napster
or
some
peer-to-peer
technologies
and
the
blockchain
Dave
structure
is
it
is
the
block
cache
blocks
and
transactions,
a
previous
block
with
mixed
temperatures?
That's
really
that
the
technology
we're
talking
about
that.
We
think
daddy.
B
So
it's
not
like!
Well,
you
can't
do
it
any
other
leg.
It's
just
what
people
get
excited
about
is
the
peer-to-peer
what's
his
performance
and
cheaper
and
more
efficient,
and
you
know
with
that
with
that
Cerner
an
idea
we
talk
about
what
certain
has
to
set
up
this
database
and
API
is
falling
and
they
have
to
back
it
up
and
do
stuff
like
that.
Theoretically,
if
you
have
a
watching
network
server,.
B
Two
or
three
nodes
on
your
baby,
some
third
party
yet
so,
if
you
know
we'll
maintain
this
for
you
for
security,
we'll
set
up
a
couple
of
bills
over
here.
Just
let
make
sure
they're
up
and
running.
Look
it's
not
going
to
go
because
unlikely
for
them
all
a
crash
right.
That's
just
excited
what
do
you?
What
do
you
do
on
disputes
as
far
as
like
delivery?
Delivery?
B
Just
speeds
a
minute
upload
this
all
those
shared
database,
but
this
guy's
a
night
shift,
50
cases
of
pork
and
this
guy's
say
I
received
48
so
which
one
gets
up
with
well,
so
surpass
so
what's
happening,
they'll
realize
that
everything
stuff
happened
that
that
single
database
to
be
enough
to
sing
that
coffee.
So,
okay,
so
that's
things
are
happening
in
a
supply
chain,
hopefully
through
some
kind
of
IOT
device,
right
scanner,
RFID
whatever.
As
soon
as
that
happens,
it's
there
right.
So
there's
you
know
the
signal
sort
of
the
truth.
B
B
I
just
read
this
that
you
know
maybe
we'll
post
it
on
popular
thing,
but
there
is
I
dreaded
release.
I
think
it
was
a
Canadian
firm.
They
implemented
a
supply
chain
for
trucking
and
they
instantly
saved
money
because
of
the
manual
states
that
they've
eliminated,
because
it's
it's
just
as
they're
doing
it's
going
right
into
the
single
source
of
truth
and
there.
There
is
because
there's
a.
B
B
Don't
know
I,
don't
answer
that
I'm
sure
they're,
you
don't
think
they
may
just
be
typing
at
the
end
and
if
they
typed
in
Toronto
it's
wrong,
or
maybe
they
have
some
kind
of
argument
for
a
manufacturer
and
I.
Don't
food
and
I
know
that
we'd
always
get
through
disputes
of
all
right.
But
my
distributor
says
there
are
48
cases
and
when
I
pull
our
records,
show
50
and
you
know,
who's
just
became
our
Ifill
who's
going
to
be
able
to
prove
it.
No
one
can
and
that's.
B
If
you,
if
you
successfully
implement
that,
could
go
away
that
could
be
the
play,
but
how
do
you
get
a
garden
five
years?
Something
has
to
be
there
to
digitally
like
actually
understand
what,
when
the
transformation
or
when
you
say
you
ordered
so
remember,
you
say
you
ordered
50
in
what
soon
as
you're
so
stimulated
public
that
public,
but
everybody
perceives
it
as
it
that
hasn't
ever
even
happened.
You
see
it.
So
when
you
put
your
order
in
it
happens,
you
see
it
right.
B
Yeah,
it
comes
to
you,
so
you
would
have
an
event
on
your
lawn
you're.
Saying
I
won't
listen
for
this
when
I
see
this
word
number
I
need
to
make
sure
it's
mask
up
and
doesn't
us
to
say
wrong.
What
would
happen
is
you
know
yeah
they
put
the
order
in
you
know.
We
say
all
right,
50
case
one
on
the
truck
the
third
party
logistics
says
we
got
50
cases
they.
You
know
the
distributor
who
says
there
were
50
cases,
but
there
was
tributed
says
we
counted
48
and
then
it's
like
well
that.
B
B
B
B
That
watching
promised
address
that
you
trust
it's
all
going
in
there
and
there's
a
way
to
hide
information,
because
it's
a
big
thing
that
people
bring
up
fabric
as
a
way
to
organize
organizations
and
blocks
or
transactions
to
say
only
these
people
can
see.
That's
right,
so
you
wouldn't
want
people
senior
workers
right
yeah,
because
other
people,
so
you
can
set
it
up
to
where
you
have
an
identity.
So
you
and
your
competitor
in
supply
chain,
your
vendors
you're
working
with
to
see
it,
but
they
would
write
founder.
B
Has
that
capability,
where
you
can
say
yeah
I
need
to
know
when
you
put
this
stuff
in
the
truck
when
they
go
from
here,
I
need
to
see
if
I
can
look
and
see
where
that's
at
and
that
everything's
in
there
now,
if
they
type
it
in
wrong,
it's
gonna
cop,
so
you'll
see
it
to
come
across
to
swatching
to
you
all
visibility.
That's.
B
Technology's
there
to
do
that
quickly
without
inventing
it
along
the
way,
I
think
that
guess
that's
what
I've
been
doing
with
with
first
shipping
company
in
Walmart
they're,
just
big
enough
voice
command
that
from
a
supply
chain.
I
know
how
big
you
are,
but
you
said
you
guys
are
all
going
to
use
this
may
or
may
not.
I
guess.
B
B
B
A
A
B
B
B
Is
Bangladesh,
which
is
very
cool?
That's
where
an
entire
blockchain
well
answer
that
I
would
use
a
cheat.
So
hyper
letter
has
an
ocean
of
channels.
So
when
I
set
up
a
peer,
no
that's
tough,
but
Clark's
a
network
right.
Each
machine
I
can
have
as
many
channels
as
I
want
and
these
channels
gonna
be
a
ledger.
Alright.
So.
B
European
and
they're
not
they're
different
they're,
not
on
the
same
in
the
locker,
store
their
separate
chains,
as
you
call
us
whatever
that's
one
way
to
do
it,
okay,
I
can
have
mini
I,
didn't
have
many
channels,
there's
a
reason
on
one
network,
they're
different
block
chains,
these
channels
of
separate
chain
right,
so
I
can
organize
without
my
Celgene,
our
channel
and
I
can
do
with
that.
Once
that's
out,
that's
your
case,
however.
I
do
think.
There's
a
lady
with
them
back
say.
Only
certain
organizations
will
get
this
information
because
they
had
to
do
that.
B
B
Away
so
they
do
have
that
kind
of
protection
to
and
permission
where
organizations
can
they
only
comes
to
their
machines.
Yes,
yes,
but
the
channel
is
the
other
Horner's
icing
factor
that
so
I
said
we're
work.
You
know,
I
can't
write
here
and
say
I'm
talking
about
these
pleasures,
don't
matter
we're
not
out
personally
doing
that,
so
I
don't
want
to
claim
that
we
know
I
just
a
lot
of
research
instead
of
our
own
network,
we're
applying
it
to
the
automation,
we're
doing
for
enterprises.
B
Now
a
lot
of
reading
site
I
feel
like
it's
still
a
technology
that
the
plan
still
will
go
back
to
the
hardest
part
is
the
beginning:
everybody,
if
you're
a
manufacturing,
Association
on
board
right.
You
could
do
it
if
you're
big
enough,
you
could
say
hey
all
my
supply
vendors,
you
participate
or
she
just
set
up
a
network
and
make
them
do
it.
B
If
you
have
to
wait,
you
know
you
could
do
that
or
might
be
better
done,
whatever
you're
making
or
manufacture
days
only
get
together
here
to
the
best
of
this
we're
all
gonna
have
more
efficiencies
and
stuff
like
that.
So
it
depends
of
you
could
theoretically
I
think
as
a
replacement
for
EDI
forget
about
source
shows
anything
like
that.
If
you
have
a
big
company,
you
want
to
share
information
with
them.
B
B
So
if
I
will
had
a
product
and
maybe
I
was
giving
out
some
kind
of
financial
information
or
sharing
stats
or
from
sheriff's
or
whatever,
like
that,
I
might
stat
sending
up
a
normal
way.
The
API
or
EDI
call
server,
but
they
all
call
I
might
just
say
you
know
what
download
this
node
here,
your
digital
certificate
fire
it
up.
Here's
the
here's!
How
you
talk
to
it,
I'm
gonna,
put
it
out
there
we
got:
we've
got
30
vendor
customers
out
there
that
I'll
have
this.
No,
those
I
don't
have
to
back
it
up.
B
The
works.
Gonna
go
ahead
and
update
this
information.
You
know
disseminate
out
to
all
the
people
they
can
interact
with
on
the
ground
right.
I,
don't
have
to
have
them
call
my
yeah.
It's
kind
of
the
same
thing:
I
think
it
might
be
more
Brazilian
cheap
overall,
instead
of
having
this
giant
robust,
centralized
server,
I
use
distributive
all
right.
No
doubt
they're,
not
my
customers
that
are
running
their
nose
for
me
over
easy
to
where
the
running
index
at
that
and
network
up
and
running,
and
they
get
a
way
to
get
it
pretty.
B
Quick
back,
please
tool,
and
it's
pushed
it
over
to
us
now.
You
know
they
don't
have
to
work
their
own
push.
You
know
mechanism
from
an
API,
so
it's
does
the
same
thing,
but
I
think
that's
a
possible
play
for
watching
technology
as
opposed
to
the
centralized
server
John,
your
question
of.
Is
it
a
lot
cheaper,
I!
Don't
know
I'm
done
again
gut
telling
these
cheaper,
because
I
don't
have
to
have
so
much
stuff
I've
done
yet.
B
B
Everything's
free
you
go
to
get
fabric
if
fabric
itself,
so
first
I've
I
haven't
been
doing
anymore.
They
they
donate
to
Linux
Foundation,
so
I
don't
see
IBM
because
they
were
the
original
authors
of
it,
but
they
don't
know
it
anymore.
They
have
their
own
people,
they
forked,
it
may
be
done
some
of
their
own
stuff,
but
hyper
leather
fabric
is
an
open-source
platform
free,
everything's
free
and
it's
got
stewarded
by
the
Linux
Foundation.
B
Everything's
free,
it's
hyper
ledger
is
the
blockchain
entity
underneath
the
Linux
Foundation
and
the
fabric
is
the
framework
under
hyper
ledger.
So
it's
really
called
hyper
literate
fabric
or
HLF.
That's
this,
but
they
have
all
kinds
of
this
is
about
hyper
ledger
has
a
saw
to
all
kinds
of
what
changes
out
here
there's
this
is
this:
is
the
population
umbrella?
This
is
a
borough
for
visual,
smart
contracts,
popular
fabrics
that
we're
talking
about
there's
decentralized.
Indeed,
sawtooth
is
name.
Is
it's
a
competitor?
B
That's
a
different
joaquin
implementation
that
fabric-
I
don't
know
much
about
it,
but
this
is
this
all
there
need
it's
all
free,
so
check
that
out
they
have
some
interoperability
between
theory,
mm
and
hyper
Ledger's
for
frameworks.
We
interoperate
that's
a
big
deal.
Theoretically,
all
these
blockchain
networks
make
their
way
out
there
interrupts
and
it
could
be
a
big
deal
right
away.
The
reason
reason
saw
two
for
reason
and
they're
already
talking
about
transactions
across
good
place,
to
go
hi
play-doh,
so
I
think
enterprise
data
sharing
is
is
is
a
killer
app.
B
This
is
a
different
way
to
look
at
distributed
customer
way
to
share
charge
forward
to
do
whatever
you
want
right.
Most
everybody
now
setting
up
API
is
centralized
API
servers
that
are
clustered
redundant,
that
people
are
calling
that
works.
What
about
you
know
more
distributed
model
like
master
a
BitTorrent,
the
same
kind
of
premise:
it
scales
better.
It
is
more
Brazilian
and
watching
Tanaka
basic
trustworthy.
That's
right!
B
B
B
How
do
we
got
started
a
while
ago?
It's
all
free
start,
your
first
network.
Basically,
what
you
do
is
you
bring
a
whole
startup
a
whole
network
on
your
machine
right
use
a
stalker,
so
you
start
it
up.
You've
got
everything
you
need
right
there
and
that's
how
I
did
it?
That's
not
reality.
I
mean
you.
Don't
you
know
that
started
all
up.
You
see
how
our
contracts
work.
Let's
go,
you'll,
get
a
feel
for
all
these
technologies.
That's
how
we
did
it's
pretty
straightforward,
so
I
would,
if
your
technical.
B
Has
to
have
a
digital
certificate,
public
private
key
to
access
the
network
can't
get
so
Bitcoin
Bitcoin!
Oh,
you
know
anybody
can
see
it
making
access
at
any
minute.
Transaction!
There's
no
permission.
So
we
have
to
give
you
something
you
just
you
generate
your
own
private
key
anybody
came
to
the
world
and
then
they
can
execute
transactions.
Anybody
there's
no
open
access
to
the
world
that
can't
do
that
if
I'm
a
supply
chain
and
I
want
to
go
ahead
and
look
at
the
database
or
put
things
in
the
database
from
a
certificate
authority.
B
B
Yes,
this
organization
can
be
into
it
they're
from
out
of
and
generate
a
public
private
key
and
give
them
a
private
key
if
you
lose
the
private
key
all
right.
So,
let's
just
PK
is
public
key
encryption
right
they
hand
their
private
key
right
and
that's
different.
If
that
isn't,
then
that's
what
he
steals
it
then
it's
fabric
has
very
robust
access
control.
B
Who
can
read
transactions
who
can
write
transaction
there's
a
whole
labyrinth
of
how
you
listen
to
I
can
make
it
really
simple,
admins
and
users
you
want
to
get
this
organization
can
do
this.
This
user
can
do
that.
I
can
do
that
very
kindly
to
provisions
it's
in
there,
so
you
can
very
granular.
So
you
that's
all
permissions,
but
they've
thought
about
all.
We
don't
want
this
organization
with
the
swords
that
you
can
execute
transactions.
This
one
can
only
read
them,
but
they
can
execute.
B
B
We
had
a
couple
things:
we
talked
about
how
a
collision
works.
We
can
talk
about
that
some
more
at
some
point
you
want
to,
but
I
would
I
think
by
going
out
and
there's
lots
of
lots
of
stuff
on
it
here.
So
you
know,
of
course,
the
biggest
killer.
App
is
cryptocurrency
for
it
right,
but
I
really
believe.
There's
some
information
share.
