A
What's
new
in
Firefly
1.1
I
have
a
a
small
demo
that
we
can
look
at
I'd
like
to
keep
this
I
I
do
have
some
slides
that
I
can
talk
through,
but
I'd
like
to
keep
this
rather
informal
and
more
of
a
discussion,
because
I
I
would
love
to
hear
from
other
folks
in
the
public
sector
Sig
about
specifically
things
that
are
interesting
topics
to
them.
So
what
I'd
love
to
do
is
just
give
a
brief
overview
of
what
Firefly
is
I
know.
A
Some
of
you
are
familiar
with
that
already,
so
I
won't
belabor
the
point
for
too
long,
but
if,
if
folks
are
unfamiliar
with
hyperledger
firefly
I
I
think
it'll
be
helpful
to
give
just
a
brief
bit
of
background.
So
we
all
are
on
the
same
page
of
what
it
is
we're
talking
about
and
then
Jim
I
know
you
gave
me
a
list
of
topics
to
that
would
be
interesting
to
the
group
and
we
could
talk
through
those
or
whatever
folks
want
to
talk
about
and
kind
of
go
from
there.
A
A
There
are
ecosystems
with
exchanges
and
tokens
and
value
and
as
well
as
all
these
DFI
apps,
that
people
are
creating
around
these
ecosystems
as
well.
So
there's
all
kinds
of
things
in
this
in
this
web
3
world,
the
Gen
1
approach
was
for
Enterprises
to
build
a
custom
platform
to
connect
to
these.
So
there
was
a
lot
of
there's
a
lot
of
custom
code
that
goes
into
every
Enterprise
app.
A
So
the
Gen
2
approach
is
to
use
a
an
open
source
platform
to
take
care
of
all
of
these
common
components
and
build
a
web3
app
on
top
of
that
common
platform
to
to
for
Enterprises
to
stop
having
to
rebuild
the
same
types
of
things
for
every
single
app
they
build.
That
common
platform
is
hyperledger
Firefly,
so
Firefly
is
what
we
describe
as
a
web.
3
super
node.
A
It
provides
familiar
things
like
like
rest,
apis
and
web
sockets,
and
things
like
that
that
developers
can
use
to
to
leverage
these
building
blocks.
That
Firefly
has
in
it
already
that
are
these
common
patterns
that
we
see
in
in
every
web3,
app
that
they
need
and
I'll
get
into
what
some
of
those
are
in
just
a
little
bit.
But
it's
this
platform
that
the
developers
can
use
to
easily
build
blockchain
apps
and
not
have
to
keep
rebuilding
the
same
plumbing
and
infrastructure
over
and
over
again.
A
So
here's
this
picture
for
me
helps
kind
of
put
that
into
perspective.
So
you
know
down
here
at
the
bottom.
Hopefully
you
can
see
where
I'm
pointing
with
my
Mouse.
You
know
you
have
you
when
you
start
thinking
about
okay,
I'm,
going
to
build
a
blockchain,
app,
well
I'm,
going
to
start
with
the
blockchain
and
I'm
going
to
start
with
a
smart
contract
that
does
the
business
logic
that
I
need
to
do,
and
then
you
know
that
that
makes
sense,
that's
kind
of
where
everybody
starts.
A
So
so
people
start
realizing.
Okay,
there's
there's
this
mix
of
things
that
need
to
go
on
the
Chain
things
that
need
to
stay
off
the
chain
and
I
need
something
to
manage
all
of
that
for
me
and
to
to
create
these
connections
between
on-chain
data
off-chain
data
to
be
able
to
transmit
to
broadcast
things
to
to
other
parties.
If
this
is
a
a
Consortium,
Network
or
or
to
privately
send
data
between
members
of
the
Consortium
I
need
something
to
be
able
to
manage
tokens,
whether
they
are
fungible
or
non-fungible.
A
A
That's
actually
going
to
deliver
value
for
my
company
and
that's
really
what
Enterprises
are
are
concerned
with
at
the
end
of
the
day
is:
is
the
business
value
so
Firefly
lets
companies
focus
on
not
building
Plumbing,
but
you
know:
what's
what's
the
actual
application?
What's
going
to
deliver
value
to
my
business
and
to
my
customers
and
focus
really
on
that
piece,
rather
than
all
of
these
rebuilding
all
these
building
blocks?
Over
and
over
again,
they
can
just
use
Firefly.
A
So
hopefully,
that
kind
of
helps
put
it
into
perspective.
Here's
a
view
of
the
the
different
things
that
are
in
Firefly.
This
is
not
an
architectural
view
per
se.
So,
as
an
engineer,
I
kind
of
look
at
this
and
go
oh,
it's
just
a
bunch
of
boxes,
but
to
you
know
to
to
somebody
who
who
wants
to
look
at
you
know
what
what
value
does
Firefly
provide.
A
That's
kind
of
what
this
this
diagram
is
describing
so
now
that
the
three
main
pillars
of
things
that
Firefly
allows
you
to
do
are
build
apps
flows
and
digital
assets,
and
so
Firefly
has
it
has
it
can
act
as
an
API
Gateway?
We
call
it
a
web
3
Gateway
and
we'll
talk
about
kind
of
the
different
modes
that
Firefly
can
run
in
in
a
little
bit.
It
has
things
that
can
generate
apis
dynamically
from
Smart
contracts.
A
It
has
a
fantastic
event:
stream
API
that
can
index
events
on
a
chain
and
provide
reliable,
either
web
hooks
or
websockets
subscriptions
to
deliver
those
events
to
your
application
and
that
that
event
bus
is
pluggable
as
well.
This
will
probably
be
a
common
refrain
throughout
the
entire
presentation,
but
just
about
everything
in
Firefly
is
pluggable,
which
means
there's.
There
may
be
more
than
one
option
for
the
implementation
of
it,
including
the
blockchain
itself.
A
Blockchains
have
plugins
and
connectors
in
Firefly,
which
means
that
the
the
actual
core
of
firefly,
which
we
see
here
in
the
middle,
is
as
strictly
speaking,
blockchain
agnostic.
It
talks
to
a
connector
that
knows
how
to
talk
to
a
specific
chain
and
there's
actually
one
of
the
the
really
new
thing.
The
new,
exciting
things
in
Firefly
1.1
is
a
framework
to
build
new
blockchain
connectors
and
we'll
talk
about
that
in
a
little
bit.
A
But
out
of
the
box,
hyperledger
Firefly
works
with
hyperledger
fabric,
all
flavors
of
ethereum
or
evm
compatible
chains
which
include
hyperledger,
Basu
Quorum,
go
ethereum
public
mainnet,
ethereum,
polygon
and
a
bunch
of
other
evm
compatible
chains.
If
it's
compatible
with
with
evm
and
Json
RPC,
it
should
work
so
and
there's
there's
also
kind
of
a
starter
kit
for
Corda
as
well
for
for
building
chord
apps
that
that
use
Firefly
as
well.
A
So
so,
like
I,
said,
there's
there's
plugins
for
everything
all
the
way
from
which
type
of
database
you're
using
to
the
event
delivery
bus,
all
the
way
to
the
blockchain
that
it's
being
used
as
well,
and
so
so
it's
a
very
it's
a
very
plugable,
very
micro
service
type
architecture,
I'm,
sorry
that
was
a
bit
of
a
tangent
from
from
this
particular
diagram,
but
I'm
getting
back
to
the
diagram.
Sorry
about
that,
so
apps
flows
digital
assets.
So
we
talked
a
little
bit
about
apps
flows.
A
I
kind
of
I
hinted
at
earlier,
so
that
there's
two
main
modes
that
Firefly
can
run
in
one
is
web3
Gateway
mode
where
Firefly
is
sort
of
my
my
API
Gateway
to
the
web3
world.
I
can
use
it
to
interact
with
public
chains
or
maybe
a
private
permission
chain,
but
it's
just
my
app
talking
to
a
chain.
The
other
mode
that
Firefly
operates
in
is
what
we
call
multi-party
or
Consortium
mode,
and
so
in
this
mode
you
may
have
multiple
organizations
that
have
come
together.
A
They
formed
a
Consortium
and
they
have
agreed
that
they
want
to
use
blockchain
to
integrate
with
each
other.
Now
they
may
be
competitors
in
the
the
space
that
they're
in
maybe
it's
insurance,
or
maybe
their
Healthcare
Providers
or
maybe
their
financial
institutions,
so
so
they
they
may
be.
They
have
varying
levels
of
trust
of
of
other
parties
within
the
Consortium,
but
they
need
to
perform
business
transactions,
exchange
data
exchange
value
and
so
Firefly
allows
you
to
build
these.
It's
rather
complex
flows
relatively
easily
with
its
API
building
blocks.
A
It
also
allows
you
to
do
things
like
I
need
to
transfer
some
value,
so
this
gets
into
the
the
third
category.
Here,
digital
assets,
there
are
there's
great
apis
for
tokens
in
Firefly,
like
I,
said
both
fungible
and
non-fungible.
And
again
this
is
pluggable.
So
there
there
are
connectors
out
of
the
box
for
erc20
erc721,
ERC
1155,
but
again
it's
pluggable.
A
So
if
you
have
a
custom
token
contract
or
or
some
other
ERC
standard
that
you
want
to
use
with
firefly,
you
can
create
a
token
connector
for
that
as
well,
but
these
digital
assets
can
also
be
linked
with
flows.
So
you
can
you
can
transfer.
For
instance,
you
can
transfer
a
token
and
Associate
data
with
that
token
transfer
that
could
be
either
broadcast
to
the
entire
network
or
it
could
be.
A
We
can
look
at
that
in
just
a
little
bit.
The
whole
thing
is
designed
to
be
run
in
a
modern
Cloud
native
infrastructure
environment,
so
kubernetes
is
kind
of
the
go-to
deployment
model
for
Firefly
and
has
Prometheus
metrics
built
right
in
so
lots,
lots
of
great
stuff
for
for
developers
and
operators
to
run
the
system
in
a
a
really
modern,
Cloud
native
way.
A
So
I
I
didn't
talk
at
Great
length
about
the
Firefly
core,
but
the
Firefly
core
is
is
one
of
the
really
important
parts
of
everything.
So
Firefly
core
is
one
of
the
micro
services
that
runs
within
Firefly
and
it's
this
orchestration
engine.
It's
sort
of
the
the
thing
that
is
connected
to
all
the
other
things,
and
so
it
is
talking
to
a
shared
storage,
bus,
a
blockchain
and
a
private
data
bus
as
well.
Right
now,
the
out-of-the-box
implementation
for
shared
storage
is
ipfs.
A
There's
a
the
private
data
bus
is
a
peer-to-peer
HTTP
with
mutual
TLS
connection.
But
again
these
are
all
pluggable,
so
they
can
be.
It
can
be
extended,
enhanced
or
used
other
implementations
as
well,
but
Firefly
core
is
doing
all
of
this
work
of
coordinating
all
these
things
that
are
happening
both
on
chain
off
chain.
It's
tracking
events
indexing
things
that
are
happening
on
chain
and
providing
an
API
for
an
application
to
use
to
query.
You
know
what
what
is
the
state
of
everything?
That's
on
the
Chain.
A
Currently,
what
events
have
happened
on
this
smart
contract
that
I
am
concerned
with
the
application,
can
also
use
fireflies
API
to
submit
transactions
to
the
blockchain
and
transfer
token
guns
and
all
this
great
stuff.
So
the
Firefly
core
is
really
the
the
piece
that
connects
all
of
the
other
pieces
in
the
Firefly
architecture
together.
A
All
right
so
I
will
we'll
kind
of
move
on
through
I'll
quickly
go
through.
Some
of
these
slides
I
won't
spend
a
ton
of
time
on
them
because
I
kind
of
want
to
like
I,
said
I
want
to
make
this
interactive.
So
some
of
the
some
of
the
cool
features
that
Firefly
has
you
can
give
it
a
smart
contract.
It
can
generate
an
API
for
you.
A
This
can
be
so
you.
If
you
have
an
ethereum
smart
contract,
you
can
give
it
the
ABI
and
it
will
generate
it
for
you.
If
you
have
a
blockchain
that
doesn't
have
a
application.
Binary
interface
format
like
like
ethereum
does,
for
instance,
hyperledger
fabric
doesn't
have
a
standardized
way
to
document
all
of
the
inputs
and
outputs
of
all
the
functions
and
events
that
are
on
a
smart
contract.
A
You
can
write,
Firefly
introduces
a
blockchain
generic
blockchain
agnostic
format,
called
a
firefly
interface
or
an
ffi,
which
is
a
way
to
describe
your
smart
contract
to
Firefly,
and
it
can
build
an
API
from
that
as
well.
So
there's
a
built-in
generator
if
you're,
using
a
a
blockchain
that
has
a
standardized
way
to
describe
a
smart
contract,
and
if
not,
you
can
you
can
write
it
yourself.
A
We've
talked
a
little
bit
about
data
flows
and
the
the
different
sort
of
communication
buses
that
Firefly
has-
and
this
is
comes
in-
really-
is
really
powerful
in
a
kind
of
this
multi-party
Consortium
mode.
That
Firefly
can
run
in
where
you
have
multiple
different
organizations
that
want
to
communicate
over
a
private
data
bus
or
to
to
share
data
throughout
the
entire
Consortium
and
and
also
using
the
the
blockchain
as
well.
A
Firefly
can
manage
digital
assets
at
scale
at
what
we
call
institutional
scale
or
at
Enterprise
scale.
So
there's
there's
great
apis
in
there
in
built
into
Firefly
for
managing
tokens,
whether
they're,
fungible
or
non-fungible.
There's
a
great.
This
is
a
screenshot
of
the
Firefly
Explorer,
which
we'll
look
at
in
just
a
minute
that
can
kind
of
show
you
the
tokens.
A
Firefly
core,
is
it's
a
like.
We
said
this
orchestration
engine
for
event:
driven
flows
I'll
skip
over
some
of
these
because
we've
talked
about
them,
just
a
a
bit
of
history
on
the
project
and
then
I'll
just
briefly
touch
on
some
of
the
things
that
are
new
in
1.1
and
then
I'll
wrap
up
my
my
slides
here
in
a
second
so
so
Firefly,
so
so.
A
A
3
application,
an
Enterprise
grade
web
3
application,
and
we
said:
wouldn't
it
be
awesome
if
there
was
a
platform
that
already
did
all
of
this
for
us
that
we
didn't
have
to
keep
rebuilding
these
same
building
blocks,
and
wouldn't
it
be
even
more
awesome
if
that
platform
were
open
source.
So
it
gains
Mass
adoption
throughout
the
world
and
and
just
and
the
community
can
contribute
back
to
it
and
enhance
it
and
grow
the
platform
as
time
goes
on
as
well.
So
that's
that's
kind
of
where
Firefly
came
from.
B
A
Can
build
a
web
3
app
easily
and
quickly
against
some
really
cool
features
in
1.1?
It's
by
far
our
biggest
release
since
1.0
there's
a
so.
This
distinction
of
Gateway
mode
and
multi-party
mode
are
something
that's
new
in
this
version,
and
along
with
that,
so
A
bunch
of
these
features
combine
to
allow
some
some
really
awesome.
New
functionality
like
being
able
to
connect
to
public
chains
and
exchange
tokens
on
a
public
chain.
A
A
So
this
allows
you
to
to
build
flows
that
actually
Bridge
multiple
blockchains,
so
Firefly
is,
is
not
by
definition
a
token
bridge
in
and
of
itself,
so
it
doesn't
necessarily
know
the
details
of
a
particular
contract
and
how
to
bridge
a
certain
type
of
asset
from
one
chain
to
another
type
of
chain.
But
Firefly
gives
you
the
connections
to
connect
to
multiple
chains
at
the
same
time,
and
you
could
build
the
logic
to
create
a
bridge
using
Firefly
and
Firefly
provides
apis
to
do
that
really
quickly
and
easily.
A
So
there's
there's
also
a
a
new
blockchain
connector
framework,
and
this
is
one
of
the
other
talking
points
that
Jim
wanted
me
to
touch
on.
Was
you
know
how
to
connect
to
different
types
of
chains?
The
the
blockchain
connector
framework
is
a
thing
that
I'm
really
excited
about.
It's
it's
a
really
nerdy
low-level
thing.
So
if
you're,
not
a
back-end
engineer,
you
you
may
just
your
eyes
may
gloss
over
at
this.
A
That's
okay,
but
for
those
of
you
that
are
and
that
are
interested
in
blockchain
protocols
and
extending
the
ecosystem,
the
blockchain
connector
framework
is
a
so
so
there's
there's
two
things:
one
is
a
an
API
contract,
not
a
smart
contract
but
an
API
contract
between
the
the
blockchain
connector
and
a
a
specific
implementation
of
a
blockchain
connector.
So
so
what
does
that
mean?
So
there's
a
golang
library
that
we
it's.
A
Firefly
transaction
manager
is
a
go
library
that
if
you
want
to
build
a
blockchain
connector
and
go,
it
probably
has
80
percent
of
all
of
the
logic
that
you
need
already
implemented
to
build
a
brand
new
blockchain
connector,
regardless
of
what
type
of
chain
you're
connecting
with,
and
the
remaining
20
is
like
how
do
what?
What
is
the
syntax
of
submitting
a
transaction
to
the
chain,
the
XYZ
chain?
Or
what
is
the
Syntax
for
querying
a
block
number
or
a
range
of
blocks
on
XYZ
chain?
A
A
All
this
stuff
is
is
implemented
in
a
blockchain
agnostic
way
inside
the
Firefly
transaction
manager,
library
or
the
blockchain
connector
framework,
as
we
call
it,
and
it's
just
up
to
me
as
a
developer
to
to
write
the
implementation
of
like
okay.
Well,
how
do
I
query
this
chain?
How
do
I
submit
the
transaction?
How
do
I?
A
How
do
I
check
for
the
current
price
of
gas
and
these
sorts
of
just
the
more
low-level
things
and
I
I'm
really
excited
to
see
where,
where
this
goes,
I'm
I'm
hopeful
that
some
some
groups
within
the
the
broader
blockchain
ecosystem
will
pick
this
up
and
build
new
connectors.
We've
been
talking
to
some
already
that
are
interested
in
building
a
connector
for
several
well-known
different
public
chains.
A
So
it's
really
exciting
to
see
where
this
will
go,
and
hopefully
it
will
be
a
huge
Head
Start
for
people
as
they
are
looking
to
build
more
blockchain,
connectors
and
enhanced
Firefly.
So,
like
I
said
it
is
a
it's
a
hyperledger
project,
so
it's
open
source,
it's
Apache,
2
licensable.
If
you're
familiar
with
hyperledger
it's
it's
everything
that
hyperledger
is
and
it
is,
it
is
a
hyperledger
project.
A
So
so
that
was
kind
of
the
end
of
that
deck
and
then
I
I
can
go
into
a
demo.
I
think
what
I
would
like
to
do,
though,
is
just
kind
of
pause
and
we're
kind
of
we've
about
halfway
through
the
today's
meeting,
so
I
think
now
it's
just
kind
of
a
natural
point
to
pause
and
ask
if
there
are
questions-
and
maybe
we
can
just
have
a
bit
of
dialogue
and
if
there
are
specific
areas
that
people
are
really
interested
in
Jim.
A
B
B
We're
gonna
have
the
recording
and
the
slides
to
post
up
later
to
the
other
groups
as
well
for
reference,
which
is
important,
but
I
can
say
on
two
sides
here:
one
I
was
in
Dublin:
I
went
to
a
lab
that
Nico
did
on
Firefly
one
one
and
the
key
is
the
labs
they
put
together
were
actually
really
well
organized
for
beginners,
because
I
was
new
to
Firefly,
so
that
was
nice.
The
other
thing
I'll
say,
though,
is
if
you
go
back
and
have
time
later,
look
at
the
slides.
B
Yes,
if
you've
ever
built,
real
blockchain,
apps
and
I
have
either
built.
You
know,
probably
three
or
four
by
now
that
are
on
different
chains,
Fabric
and
and
so
on,
some
other
ones,
and
if
you
look
at
building
that
whole
solution
and
also
as
an
architect
I've
had
a
chance
to
look
at.
Probably
a
dozen
more
in
detail
as
well.
B
If
you
go
through
his
slides,
there
isn't
a
lot
that
they
that's
outside,
of
what
I
call
the
scope
of
firefly
that
you
have
to
build
and
that's
actually
a
huge
huge
win
so
actually
and
I
wanted
I'll
grab
something
on
my
end:
I'm,
not
cheap.
So
in
one
second,
there's
a
there's,
a
slide
I'm
going
to
talk
to
which
is
sort
of
a
it's
one.
He
showed,
and
let
me
just
flip
it
up
real
quick.
So
let
me
share
my
screen
real
fast,
it's
this.
So
you
can
see
my
screen
right.
B
There's
a
lot
more
going
on
honestly,
on
the
left
hand,
side
if
you're,
building
a
blockchain
app,
then
just
what
he
shows
here
and
so
a
lot
more
actually,
and
if
you
go
over
here
to
the
right
hand,
side
you
get
what
I
call.
This
is
what
I
call
the
commercial
slide.
So
if
I
look
at
my
own
company,
dtcc
and
say
hey,
we've
got
blockchain
apps
to
build
and
I'm
saying:
okay
in
theory,
this
is
a
theory
not
a
reality
over
here.
B
This
big
fat
purple
box
is
what
I'm
getting
from
Firefly
the
chains
down
here.
I'm
still
building
the
same
way,
so
Nico
jump
in
and
correct
me
wherever
I
make
a
mistake
here,
but
I'll
say
whatever
I'm
doing
on
the
blockchain
itself,
the
smart
contract
definitions
and
so
on
that
part
of
the
setup
is
still
done
down
here.
It's
the
rest
of
this
infrastructure
that,
in
a
sense
we're
saying
this
is
potential
gain.
B
B
I've
got
and
saying:
hey,
you
know
what
we
built
them
a
certain
way:
they're,
okay,
but
they're,
not
really
well
architected
and
the
thing
I'll
say
about
Firefly
the
thought
behind
it
is,
although
it's
strong
from
an
architecture
perspective
as
Nico
said,
there's,
this
concept
of
everything
can
in
a
sense
become
visible
if
you
will
to
the
applications
and
services
that
need
them
on
the
event,
bus,
which
is
a
huge
I'll
call,
it
benefit
to
building
a
solution.
The
other
benefit,
obviously,
is
you
can
see.
B
He
went
through
the
component
slide
about
all
the
different
component
Services,
because
there
are
different
Services,
it
means
and,
as
he
said,
a
lot
of
those
are
pluggable.
Those
Services
generally
have
called
conceptual
interfaces,
if
not
real
interfaces,
which
is
why,
in
many
cases,
they're
pluggable.
So
in
my
case,
if
I
want
to
and
yeah
I'll
say,
I'm
looking
at
existing
apps
we've
built
in
blockchain
that,
for
instance,
don't
use
an
event
bus
or
don't
have
a
common
architecture
across
different
blockchain
platforms,
you're
trying
to
connect
if
I
said,
okay.
B
B
Yes,
this
left-hand
stuff
is
available
and
even
more
in
the
component
diagram
that
Nico
showed,
on
the
right
hand,
slide
if
it's
a
green
field,
app
yeah
I'm,
going
to
benefit
from
the
bulk
of
this.
If
it's,
what
I
call
an
existing
app
or
a
Brownfield,
app
I'll,
say
well
I'm
going
to
have
to
refactor
some
of
the
stuff
that
I
will
want
to
reuse,
some
of
it.
I
won't
but
I'll.
Let
Firefly
kind
of
build
the
framework
and
then
choose
what
I
have
to
modify
in
here.
B
So
there's
still
more
work
to
be
done
on
this
side
and
even
in
a
Greenfield
app
I
would
say,
but
the
idea
is
even
if
I
realize
what
a
small
section
of
this
potential
that's
a
massive
net
gain
in
three
areas
in
time
cost
and
improve
quality
because
they
didn't
have
to
write
the
code.
There's
less
quality
work
to
build
a
quality
application,
there's
less
testing
and
debugging
for
the
stuff
that
already
Works
a
standard,
Firefly
components
for
short.
B
So
those
are
the
potential
gains,
even
if
I
don't
realize
the
entire
purple
block
there
as
a
Net
game
for
my
organization
on
any
app.
So
with
that,
let
me
flip
it
back
to
you,
Nico
I'm,
going
to
take
a
look
at
the
chat
and
see
some
of
the
questions
there,
but
give
me
the
thing
that
I'm
most
interested
I
guess
is
first
walk
me
through
from
your
perspective,
say:
I
have
a
really
trivial
app.
B
You
know,
I
know
your
lab.
The
nft
things
we
had
one
is,
you
know,
create
the
nft
and
then
we,
you
know
we're
doing
I,
think
transfers
of
an
nft
sales,
if
you
will,
whatever
redemptions
and
so
on.
If
you
were
building
a
new
app
and
you
can
use
I,
don't
care
if
you
use
ethereum
or
fabric
as
your
base
blockchain,
but
walk
me
through
what
I
call
from
your
perspective
the
right
flow
given
Firefly
as
my
tool
set.
B
A
Yeah
great
question
and
so
I
think
I,
I
and
I
think
the
initial
starting
point
is
actually
going
to
be
the
same
for
what
you
described
as
the
Brownfield
application
as
well,
where
you
want
to
refactor
an
existing
app
to
use,
Firefly
and
I.
Think
actually,
the
right
place
to
start
is
really
just
trying
to
wrap
your
head
around.
What
does
like
what
are
the
actual
functions
that
Firefly
gives
me?
What
are
the
building
blocks
and
so
I'll?
Just
briefly,
I
see
there's
a
lot
of
great
questions
in
the
chat.
A
A
But
doing
is
the
thing
that
makes
it
real
for
me
and
so
for
for
all
of
the
people
who
learn
by
doing
out
there,
there's
a
great
getting
started
guide
that
walks
you
through
how
to
set
up
the
the
Firefly
command
line
interface,
which
is
the
the
thing
that
will
run
Firefly
on
your
computer
and
so
I.
Think
really,
the
best
way
to
get
started
is
like
to
just
get
your
hands
on
it.
Try
it
see
what
it
does.
Look
at,
you
know,
try
all
the
different
functions
in
it,
so
Firefly
command
line
interface.
A
Will
this
you
could
download
a
a
binary
build
from
GitHub
here's.
The
latest
release
you
can
just
come
down
here
pick
the
right
one
for
your
operating
system
and
CPU
architecture.
You
can
also
use
go
install
to
install
that
as
well,
but
once
you
once
you've
installed
this,
it's
really
easy
to
set
up
Firefly
on
your
computer.
It's
a
little
diagram
of
everything
that
will
set
up
for
you.
It's
going
to
use
Docker,
but
it's
you
just
have
to
type
FF
and
it
and
then
you
can
name
your
stack.
A
You
could
pick
the
number
of
members
the
default
is
to
run
it
in
a
multi-party
Consortium
mode.
If
you
want
to
run
it
in
a
web
3
Gateway
mode.
There
are
command
line
flags
for
that.
There
are
a
bunch
of
different
switches,
so
say:
you're
like
well:
I
want
to
try
hyperledger
Firefly,
with
hyperledger
fabric
in
a
multi-party
mode
and
I
want
to
use
postgres,
as
my
database
and
I
want
to
enable
Prometheus,
metrics
and
there's
there's
Flags
to
do
all
of
that
to
to
and
this
list
that's
in.
A
A
What
does
that
give
you
so
it'll
give
you
a
all
it'll
give
you
Firefly
and
all
of
its
services
for,
say:
I
picked
three
members
here
in
in
the
in
the
docs,
so
it
gives
you
a
web
UI
and
a
sandbox
UI
for
each
one.
The
sandbox
is
a
great
place
to
start
I'll
actually
hop
over
to
I
have
a
if
I
can
get
this
Zoom
window
out
of
the
way
here.
A
I
have
Firefly
running
so
here's
my
here's,
my
Firefly
Explorer
and
I
also
get
the
the
Firefly
sandbox,
and
so
we
talked
about
kind
of
the
three
pillars
of
firefly
and
the
kind
of
the
three
main
buckets
of
functionality
and
those
are
messages,
tokens
and
contracts.
So
I'll
start
with
messages
because,
like
it
sounds
really
basic
and
it
is,
it
is
it's
like
many
of
fireflies.
A
It's
it's
an
event
driven,
but
most
most
blockchain
apps
end
up
needing
to
be
event
driven
just
because
blockchains
are
event
driven,
and
so
there
there's
a
lot
that
you
can
actually
accomplish
just
through
using
messaging
and
and
the
messaging
is
backed
by
the
chain
itself.
So
most
people
immediately
think
oh
I
need
a
a
custom
Smart
contract
to
do
business
logic.
A
Xyz
yeah,
like
you,
can
do
that
and
I'll
get
to
that
in
just
a
minute,
but
I
would
encourage
people
to
kind
of
back
up
and
just
like
take
a
look
at
what
Firefly
does
and
all
the
functions
that
it
has
built
in
and
and
see.
If
you
can
map
those
to
the
business
constructs
that
you
have
in
your
app
many
times.
A
Those
are
pretty
hard
problems
very
specialized
development
as
well.
Firefly
still
gives
you
that
control.
If
you
want
that
level
of
control-
and
you
need
it,
but
it
has
a
lot
of
really
powerful
functions
built
in
so
some
of
the
things
that
I
would
encourage
people
to
look
at
are
in
broadcast
messaging.
So
this
is
like
I
want
to
send
some
data
to
everyone
in
my
Consortium.
It
can
be
a
it
could
be
a
string.
A
It
can
be
a
Json
object
that
Json
object
can
so
I
can
define
a
data
type
in
my
network,
so
I
can
Define.
Like
this
is
what
the
here's,
the
Json
schema
for
a
customer
record,
so
I'm
going
to
broadcast
like
I,
have
a
new
customer
record
or
a
new
order
that
was
placed
in
the
in
the
system.
You
can
Define
these
data
types
and
everyone
agrees
okay.
This
is,
we
all
understand
what
we
are
talking
about
when
we
say
a
customer
record
or
an
order
number
or
something
like
that,
and
then
you
can.
A
A
A
There's
you
can
optionally,
pin
the
data
to
the
chain
or
you
can
keep
it
entirely
off
chain
as
well.
So
that's
another
option
just
for,
if
maybe
you
have
a
part
of
your
application
that
actually
doesn't
or
shouldn't
use
blockchain
at
all.
There's
there
are
varying
degrees
of
like
how
much
you
want
to
use
the
chain
in
all
this
hopping
over
to
the
tokens
tab.
A
This
particular
Firefly
node
sandbox,
is
not
set
up
to
actually
do
tokens
here,
so
I'm
not
actually
going
to
push
the
buttons,
but
if
there's
a
token
contract
on
chain
already,
it's
just
really
easy
to
connect.
Firefly
to
that
I
can
put
in
the
contract.
Address
I
can
tell
it.
Is
it
fungible
or
non-fungible,
and
you
know
what
block
number
you
want
to
start
indexing
from
I'll
just
hop
over
to
the
the
Explorer
UI,
and
so
you
I
I,
do
actually
have
a
so
I'm
going
to
switch
names
I.
A
This
Firefly
node
is
connected
both
to
a
private
fabric
Consortium
and
a
public
polygon
test
net
as
well.
So
if
I
switch
to
the
polygon
namespace
and
then
I
hop
over
to
my
tokens,
tab
I
can
see-
let's
see
in
the
last
30
days
a
little
about
this
time
out.
So
this
was
a
token
contract
that
I
deployed
during
global
forum.
I
can
see
I
minted
a
hundred
tokens,
probably
right
before.
A
Probably
this
is
probably
the
day
before
the
presentation
I
I
transferred
some
of
them
during
my
demo
in
real
time
and
I
think
I
minted
some
more
during
the
demo
and
then
actually
just
this
morning,
I
said:
hey
I
should
make
sure
this
stack
is
still
working
so
from
my
metamask
wallet,
I
transferred
10
tokens
back
to
the
wallet
that
Firefly
is
using,
so
really
really
cool,
really
easy
to
use
token
capabilities
here.
The
really
powerful
thing
is
that
Firefly
is
aware
of
all
these
things
that
are
happening.
A
It's
it's
keeping
track
of
the
balances
of
all
these
tokens
so
that
it
provides
a
really
easy
to
use
API
that
I
can
just
query
say:
hey,
what's
the
balance
for,
for
this
account,
what
is
the
what's?
The
entire
history
of
this
nft
token
and
all
the
times
that
it's
been
transferred,
blockchains
themselves
are
not
particularly
good
or
optimized
for
answering
some
of
those
questions
quickly.
Normally
so
so
Firefly
provides
a
lot
of
functionality
around
that
so
I
I
apologize.
A
If
this
was
like
just
just
a
segue
into
my
regular
demo,
but
getting
back
to
Jim's
question
like
I
think
just
kind
of
to
start,
where
I
would
start
is
like
just
just
explore.
Firefly
use
the
sandbox
use
the
there's,
also
a
Swagger
UI
for
all
of
the
endpoints
on
here
play
around
with
this.
You
can
you
can
post
here
to
define
a
data
type
instead
of
doing
it
through
the
sandbox.
A
If
you
want
as
you're
doing
stuff
through
the
sandbox,
it's
dynamically,
creating
code
samples
that
you
can
use
if
you're
writing
a
a
node.js
or
typescript
app,
and
you
want
to
use
the
Firefly
SDK,
it's
generating
the
code
on
the
Fly
here
that
you
would
use
to
put
in
your
application
to
do
the
specific
operation
that
you're
doing
here
in
the
sandbox,
so
really
powerful
tool
just
for
learning
about
fire
fly.
But
it's
really
this
exercise
of
like
just
understanding.
Okay,
what
what
are
the
building
blocks?
A
That
Firefly
gives
me
and
then
sort
of
mapping
that
to
like
what
are
the
things
that
my
business
application?
My
my
business
logic
flow
needs
to
do,
and
you
know
trying
to
see
like
do
the
building
blocks
that
have
been
provided
cover.
All
the
functionality
that
I
need,
or
maybe
I
do
need
to
go
into
the
kind
of
the
third
door
here
of
custom
contracts,
and
then
that's
okay,
Firefly
lets
you
do
that
as
well.
A
You
can
use
Firefly
to
interact
with
a
completely
custom
Smart
contract
and
you
get
all
of
the
the
rich
indexing
and
really
easy
transaction
submission
features
of
Firefly.
So
so
that's
where
I'd
start
and
I
think
the
same
is
true
for
building
a
Greenfield,
app
or
refactoring.
An
existing
app
is
just
sort
of
this.
A
This
mapping
of
like
okay,
what
what
does
Firefly
do
and
like
how
can
I
what
parts
of
my
application
can
I
leverage
to
to
do
that,
and
hopefully
it
should
be
a
lot
of
it
and
it's
it's.
The
type
of
thing
too
like
if
you
have
questions
about
it,
come
come,
ask
us
in
the
in
the
Firefly
Discord
Channel.
We
love
to
chat
about
this
type
of
stuff
to
help
people
brainstorm
like
how
can
I
accomplish
XYZ
or
fill
in
the
blank
with
with
firefly
we'd
love
to
chat
about
it.
B
A
Absolutely
so
so
the
flows
are
really.
It's
Firefly
allows
you
to
build
the
flows
in
your
application,
so
we've
had
questions
of
like
well
does,
can
you
do
bpmn
or
or
with
firefly
in
it?
The
answer
is
like
Firefly
itself
doesn't
do
bpmn,
but
it
it
gives
you.
So
it
gives
you
an
API
and
it
gives
you
an
event,
bus
that
are
really
easy
to
to
use
either
through
websockets
or
web
Hooks,
and
allows
you
to
to
build
the
the
off-chain
logic
of
like
okay.
This.
A
This
event
happened
here
now
I'm
going
to
go.
Do
this
operation
on
another
chain,
whether
that's
another
L1
chain,
or
whether
it's
a
private
chain,
and
so
so
so
so
so
the
answer
is
yes.
Firefly
allows
you
to
to
build
that
functionality
absolutely
and
it
doesn't
matter
whether
the
chain
is
L1
L2,
whether
it's
public
or
private
Firefly
can
connect
to
both
of
them
and
and
give
you
the
events
as
things
are
happening
on
each
chain
and
allow
you
to
submit
transactions
to
either
one
and.
B
One
other
thing:
there's
a
question
about
fabric,
but
I'll
just
say
in
general:
the
concept
of
fabric
has
a
lot
of
features
in
its
own
I'll
call
it
network,
if
you
will
that
they
built
into
it
that
some
of
the
other
blockchains
don't
by
default.
But
that
said,
if
you
think
about
Firefly,
it's
a
layer
or
above
it's,
the
application
layer
over
your
blockchain
network,
as
you
show
it
in
the
diagrams.
So
what
that
means
is
to
have
a
common
architecture
and
a
common
set
of
services
across
multiple
blockchains.
B
In
some
cases,
you,
like
fabric,
is
a
good
example.
You
wind
up
implementing
a
feature
that
fabric
already
has
differently
in
Firefly
right.
So
the
the
specific
question
really
talks
about
the
fact
that
in
fire
propriet
says,
can
we
use
Firefly
in
place
of
the
Gateway
SDK
that
is
already
provided
by
fabric
to
get
to
our
contracts
and
I?
Think
the
answer
to
that
is
yes,
through
the
fabric
connector,
there's
also
and
fabric,
they
give
you
very
nicely
something
called
a
certificate.
Authority
manager,
that's
actually
pretty
power
powerful.
B
A
Yeah,
so
so
just
a
couple
of
things
there
so
we're
we're
very
aware
of-
and
some
people
have
mentioned
like,
oh
well,
if
you're
blockchain
agnostic,
then
your
least
common
denominator
and
like
I'm,
very
aware
that
that
is
a
potential
Pitfall
that
the
that
the
project
could
fall
into
I
I.
Don't
think
we
are
that
that's
not
the
road
I
want
to
go
down
and
I,
don't
think
we're
going
down
that
road.
A
I!
Look
at
it
from
from
this.
From
the
perspective
of
like
there,
there
is
a
set
of
business
problems
that
I
need
to
solve
and
what
is
what's,
the
common
set
of
functionality
that
I
need
from
any
chain
and
and
and
looking
at
it,
sort
of
from
the
other
direction
rather
than
like?
Oh
well,
because
I
built
on
Firefly
I,
don't
get
featured
XYZ
from
from
a
certain
chain.
A
It's
also
worth
saying,
like
there's
nothing,
stopping
you
from
going
and
using
a
specific
feature
in
a
specific
Chain
by
by
talking
to
that
chain
or
or
the
blockchain
connector
for
that
specific
chain,
as
well.
With
regard
to
the
fabric,
Gateway
SDK
and
the
ca,
so
Firefly
uses
these
things
behind
the
scenes.
There
is
actually
a
specific
open
issue
to
upgrade
to
using
the
Firefly
sorry,
the
fabric,
Gateway
SDK,
we're
using
the
the
old
SDK
right
now,
because
right
Firefly
is
still
compatible
with
fabric.
A
A
The
idea
is
that
that
that
it
is
the
platform
that
you
can
build
your
app
on
top
of
and
it
doesn't
like,
you
could
actually
switch
chains
later.
If
you
build
your
app
specifically
to
use
the
fabric
Gateway
SDK,
you
can't
switch
to
using
an
ethereum
chain
later
and
that's
that
is
one
of
the
powerful
things
of
fireflies
that
if
you
build
to
fireflies
API,
you
can
use
any
of
the
plugins.
That
Firefly
supports.
B
Yeah
and
actually
you
hit
well
what
I
guess
I
really
like
compared
to
other
solutions.
That
I'm
aware
of
I'll
say
is
the
fact
that
I
have
the
choice.
The
control
is
on
my
end,
so
that
I
can
say.
Oh
cool
Jim
wants
to
build
across
three
different
blockchains
and
I'll,
just
use
Firefly
quickly
out
of
the
box
and
follow
what
I
can
do
there.
But
what
I
really
like
is
I.
A
B
You
know
I,
don't
want
to
be
the
guy.
Well,
I'm
glad
I'm,
not
the
guy
that
writes
the
fabric
connector.
Let's
put
it
that
way
for
you,
because
that
guy
will
have
to
come
up
with
some
smart
answers.
So
he'll
say:
oh
yeah,
I'm,
the
brilliant
guy
that
figured
out
out
how
I
can
support
both
the
Old
and
the
new
model
for
fabric
tutu
and
whatever
is
2-5
or
something
like
that
with
the
Gateway
SDK
that
that
opportunity
is
really
up
to
you
know
your
team
collido
to
figure
out.
B
A
Yeah
yeah
I
a
couple
other
great
questions
here
in
the
in
the
chat
I'm
going
to
try
to
hit
some
of
these
rapid
fire
does
Firefly
support
token
definition
Management
on
fabric.
The
answer
is
it?
Could
we
somebody
would
need
to
write
a
token
connector
that
talks
to
fabric
in
order
to
do
that?
But
it's
it
most.
Certainly.
Could
we
just
don't
have
a
there
has
not
been
a
demand
for,
or
anybody
really
asking
for
a
token
connector
for
fabric,
but
it
most
certainly
could
commercial
adoption
so
far.
A
A
We
have
many
different
customers
in
different
Industries
off
the
top
of
my
head,
I
I'm,
an
engineer
so
I
I
have
trouble
remembering
which
ones
I
can
talk
about
and
which
ones
I
can't
but
industries
from
from
Healthcare
to
Insurance
to
quite
a
few
different
Financial
applications
as
well.
There's
there's
quite
a
bit
of
commercial
adoption
already
and
new
solutions
that
we're
working
on
all
the
time.
Yeah.
B
One
one
big
area
I
do
want
to
hit
that's
important
not
only
to
my
company,
but
obviously
a
lot
of
people
in
the
chat
too.
There's
a
bunch
of
identity,
Frameworks
based
on
self-sovereign
identity,
kids,
verifiable
credentials
and
all
that
and
we're
trying
to
figure
out
in
a
sense.
What
the
smart
way
to
integrate
to
one
of
those
networks
might
be
as
an
example.
So
I
don't
know
in
the
I'll
call
it
the
work
that
Collide
is
already
doing,
I'm.
Sure
somewhere
they've
already
taken
a
look
at
those
kind
of
projects
and
I.
B
Don't
know
if
there's
any
kind
of
a
guidance
document
that
you
might
have
or
a
page
that
talks
about
if
you're
running
an
identity
Network
it
could
be
Sovereign
could
be
various
could
be
a
bunch
of
different
ones
out
there
with
those.
How
would
I
map
an
identity,
credential
framework
like
that
into
the
Firefly
world
without
having
to
have
you
build
upload,
a
whole
new
version
to
do
that?
Yeah.
A
A
Think
one
of
the
big
takeaways
from
this
year's
hyperledger
global
forum
for
me
was
just
kind
of
the
momentum
around
self-sovereign
identity
and
the
the
work
that
is
going
on
in
Indiana,
Aries
in
hyperledger
and
and
the
need
for
the
the
folks,
the
Firefly
maintainers
to
to
get
together
with
some
of
the
folks
on
those
projects
and
talk
about
like
what.
What
can
we
do
to
integrate
these
things?
The
identity
I'll
refer
to
it,
as
the
identity
story
in
in
Firefly
is
not
done
yet.
A
B
A
A
A
A
namespace
either
runs
in
multi-party
mode
or
it
runs
in
Gateway
mode.
So
you
you
could
have
so
so
like
in
my
in
my
environment
that
I
just
showed
a
minute
ago.
I
have
two
namespaces
configured:
I
have
one
that's
a
fabric.
Network
and
I
have
one
that's
a
public
polygon
test.
Now
you
could
have
there,
there
could
be
overlap
between
you
know.
An
organization
could
be
in
multiple
namespaces
a
and
so
so.
A
So
yes
and
no-
but
it's
sort
of
this,
this
grouping
of
like
in
this
namespace
I'm
talking
to
this
blockchain
I'm
using
this
database,
I'm
I'm
running
in
multi-party
mode
and
I
have
I.
Have
this
ipfs
instance
that
I'm
using
for
this
namespace
and
over
here
I
have
I
may
have
the
same
chain.
I
may
have,
and
I
may
be
running
in
a
different
mode,
or
it
could
be
a
completely
different
chain.
It
could
be
a
different,
could
be
public
ipfs,
it
could
be
a
different
database.
A
A
How
does
one
create
a
channel
like
in
Fabrics
CLI
through
Firefly,
so
Firefly
is
not
an
infrastructure
management
tool?
So
it's?
It
is
not
it's!
It's
not
in
scope
for
Firefly
to
manage
the
actual
blockchain,
so
so
things
like
Firefly
doesn't
actually
deploy
a
contract
for
you.
Firefly
itself
does
not
actually
set
up
a
blockchain
for
you.
That
being
said,
the
Firefly
command
line
interface
is
a
a
developer
tool
that
will
do
some
of
those
things
for
you
on
your
local
machine.
A
It
does.
If
you
want
to
use
fabric,
it
will
set
up
a
a
relatively
trivial
fabric,
Network
on
your
machine.
It
can
deploy
smart
contracts
to
chains
on
your
machine.
It
is
not
a
Production
Tool
though
so
I'll
just
say
that,
like
creating
a
channel
is
how
you
would
normally
create
a
channel
in
Firefly
using
right,
pure
commands,
sorry
in
fabric,
not
Firefly
too
many
hyper
Ledger
words
yeah.
B
But
no
fabric,
you're
right
fabric
has
mini
fabric
as
a
tool,
there's
actually
a
very
good
if
you're
looking
at
fabric
there's
a
brand
new,
what
they
call
full
stack
fabric
tutorial,
they
just
built
that
does
deploy
directly
to
kubernetes
as
well.
So
you
know
if
you're
looking
at
really
fabric
go,
take
a
look
at
that
tutorial,
come
back
and
take
it,
go
through
the
getting
getting
started
on
Firefly
to
figure
out
how
Firefly
works
and
can
in
a
sense
build
something
quickly.
B
But
the
key
thing
is
that
the
base
Fabric
in
a
sense
is
easy
to
do
in
many
fabric.
Second
thing
is
you're
going
to
build
your
contracts
over
the
last
thing.
I
we
I
want
to
look
back
on
the
language
piece.
You
said
we
have
node.js
typescript
our
sdks
available.
Do
I,
have
a
Java
SDK
available
as
well.
A
There
is
not
one
currently
available,
but
would
love
if
somebody
wants
to
contribute.
One
there's
also.
Our
approach
has
been
to
generate
as
much
of
the
SDK
as
we
can
from
Firefly
has
a
pretty
comprehensive
Swagger
definition
that
is
is
part
of
firefly
and
like
I
I
have
a
love-hate
relationship
with
generated
sdks.
A
On
the
one
hand,
they're
they're
really
great
for
being
able
to
stay
in
sync
with
the
the
API,
sometimes
the
user
experience,
the
developer
experience
leaves
some
to
be
desired,
so
sure
yeah,
that's
been
our
approaches
to
to
use
the
the
Swagger
definition
as
much
as
we
can,
but
also
still
provide
a
good
developer
experience
as
well.
Okay,.
B
B
I
can
grab
that
and
just
throw
it
over
the
fence
and
say
here.
This
is
how
it
works
and
it
looks
funny.
It
looks
like
exactly
what
we
wanted
to
build
anyway.
So
it's
kind
of
nice
to
see
the
documentation
at
the
level
you
have
it.
So
that's
great
with
that.
I
realized.
You
know.
Unfortunately,
we
could
go
on
for
only
about
four
days
to
answer
more
questions,
but
we
don't
have
that
time.
B
So
I
do
want
to
thank
Nico
very
much,
really
excited
that
collido
has
done
this
phenomenal
framework,
really
like
the
clean
Arc,
not
only
the
architecture,
what
they're
doing,
but
also
the
fact
that
they
say
these
are
the
boundaries.
So
we
allow
you
what
I
call
the
interface
to
talk
to
any
blockchain.
We
give
you
connectors
to
start
with
those
kind
of
things,
so
it's
really
a
well
thought
out
solution
for
sure
and
selfishly
I
intend
to
use
it
many
many
times
within
my
own
company,
so
I
hope
the
rest
of
you
will
follow.
B
Certainly
Nico
collido
is
going
to
produce
more
stuff
on
this
and
I
would
also
say.
The
community
is
also
not
just
myself,
but
many
others
in
the
community
will
probably
also
start
sharing
some
of
our
experience
on
Firefly.
So
with
that,
thank
you
again.
Nico.
It's
been
awesome.
I've
got
to
stop
the
recording
at
this
point.
All
right
get
back
to
data
everybody
else.
Yeah.
A
Just
just
real
quick
thank
you
Jim.
Thank
you,
everyone
for
for
inviting
me
here
today.
I
will
share
the
slides,
I'll,
send
them
to
you
Jim,
and
then
you
can
post
them
to
to
the
Sig
page.
If
you,
if
you
want
to
stay
in
touch
after
this
hyperledger
Discord,
come
find
us
in
the
Firefly
Channel
and
happy
to
chat
more
about
Firefly
there.
Thank
you.
Everyone
really
appreciate.
