A
Getting
the
streaming
going
now
so
you're
welcome
to
start
whenever
you
like
lovely.
Thank
you
it's
great
to
see
so
many
people
on.
As
you
know,
we
will
start
with
an
overview
of
the
last
six
months
or
half
or
three
months
what
has
been
going
on
in
hyperledger
and
then
we'll
dive
deeper
into
cactus.
I'm
really
excited
actually
about
that
presentation,
because
I
really
want
to
learn
more
and
I'm
sure
you
all
do
so.
I'm
not
gonna
keep
you
waiting
too
long.
B
A
Okay,
here
we
go
sorry
for
that,
so
we
are
really
going
strong
right
now.
We
have
we've
been
around
for
four
years
now
we
have
16
projects,
which
is
pretty
crazy.
We
have
one
production
release
in
1.0
and
two
for
sorry,
four
in
1.0
and
one
in
2.0,
so
the
code
bases
are
really
maturing
right.
Now
we
have
really
active
community
and
working
groups
and
obviously
the
meetups
are
also
growing
strong.
A
You
know
about
hyperledger
well
enough,
so
you
know
that
we
have
a
modular
approach,
we
think
of
ourselves
as
a
greenhouse,
and
this
is
our
greenhouse
right
now,
since
we
started
or
since
the
beginning
of
the
year,
we
have
added
some
projects
here,
so
we
have
hyperledger
cactus,
most
importantly,
and
then
shortly
before
the
end
of
the
year,
we
also
added
aries
and
transact
and
avalon
we
have.
The
major
highlights
from
our
projects
is
that
there
is.
A
We
are
really
we're
trying
to
get
more
people
engaged.
We
have
launched
a
hyperledger
fabric,
documentation
working
group,
or
rather
it
was
already
running,
but
we've
put
a
lot
of
effort
into
activating
it,
and
now
we
have
I'm
very
pleased
to
announce
that
we
have
fabric
documentation
and
plethora
of
languages.
A
A
So
a
bit
about
our
newest
projects,
hyperledger
cactus,
is
what
we'll
be
hearing
about
today.
So
I'll
I'll.
Let
you
listen
to
peter.
It
is
basically
a
blockchain
integration
tool
that
is
designed
to
allow
users
to
securely
integrate
different
blockchains
we
do
are.
We
are
developing
our
certified
certification
programs.
We
have
now
certified
hyperledger
fabric
developer
course,
along
with
hyperledger
fabric
administrator
and
a
hyperledger
assault
administrator
courses.
A
This
helps
our
community
to
get
professional
certification
that
hopefully,
will
help.
You
also
get
better
jobs
and
be
more
recognized
in
in
the
world
or
in
the
professional
world.
We
have
launched
actually
also
courses
along
around
self-sovereign
identity,
so
the
team
at
sovereign
has
been
working
and
government
of
british
columbia
has
been
working
and
developed
a
really
good
course
on
in
the
aries
in
ursa,
and
then
the
second
one
on
becoming
a
developer
of
hyperledger
aries.
A
If
you
are
interested,
please
go
to
the
training
page,
that's
where
we
all.
We
have
all
of
the
details
on
the
training.
We
are
really
developing
and
improving
our
blockchain
showcase.
Currently,
we
have
over
65
projects
that
have
been
submitted
by
people
like
you
that
have
been
developing,
that
have
been
working
with
hyperledger
code
bases
and
develop
something
great
and
you
don't
have
to
be
a
member
to
develop
to
submit
to
the
blockchain
showcase.
A
A
A
This
program
is
targeted,
obviously
at
companies,
but
it
does
require
companies
to
get
at
least
three
certified
developers
or
administrators.
So
as
individuals,
you
might
want
to
be
considering
the
certification
we've
had
some
updates
in
terms
of
events,
obviously
the
biggest
one
and
the
most
exciting
one
was
hyperledger
global
forum.
A
It
was
probably
one
of
the
last
big
conferences
that
happened
before
the
lockdown
global
lockdown.
It
was
very
well
attended,
given
the
climate
and
the
situation
we
had
over
450
attendees,
we
had
over
90
sessions
and
all
of
them,
as
a
matter
of
fact,
are
recorded
and
available
on
our
youtube
channel
along
with
the
presentations.
A
We
had
a
great
talk
from
sweta
and
tracy
about
what
does
it
mean
to
be
an
open
and
inclusive
community,
and
we
really
want
to
make
sure
that
we
are
hearing
feedback
from
you
when
you
feel
in
some
way
intimidated
or
not.
Feeling
like
the
community
is
really
open
to
diverse
diverse
attention
attendance.
A
The
global
media
community
has
grown
amazingly
through
lockdown
and,
having
you
know,
a
very
hard
time
attending
meetings
in
person.
Actually,
our
meetup
has
a
meet-up
system
or
program
has
really
grown
because
all
of
a
sudden
we
are
all
connected,
and
while
we
can't
see
each
other
in
person,
we
can
attend
meetups
that
are
just
virtual
and
global.
I've
recently
gave
a
talk
at
a
meetup
that
was
organized
by
hyperledger
sweden,
but
actually
we
had
people
from
africa
and
from
munich
and
from
finland
as
well
so
really
diverse
community.
A
We
have
over
2
000
attendees
in
total
and
loads
of
views
on
of
the
recordings
on
the
youtube
channel,
and
we
have
a
very
good
set
of
speakers
as
well,
which
is
important
to
us,
because
there
is
no
point
in
having
a
meetup.
If
you
don't
really
have
anything
to
discuss,
so
there
are
great
great
companies
and
organizations
that
are
able
to
talk
about
it.
A
A
Our
chapter
in
brazil
and
latin
america
have
launched
and
were
launched
and
are
running
regional
events
in
portuguese
and
spanish.
That's
part
of
what
we've
been
doing
of
opening
the
hyperledger
to
other
languages
and
recognizing
that
one
of
the
big
barriers
in
participation
in
a
project
like
hyperledger
is
that
it
is
only
in
english
and
then
we
have
a
really
active
community
in
africa.
A
We
have
ran
two
virtual
events
about
hyper
ledger
and
they
are
now
planning
for
a
monthly
event
series.
We
have
more
and
more
learning
resources.
As
a
matter
of
fact,
there
is
a
study
circle
and
that
hyperledger
sweden
has
started.
You
can
join
the
join
the
historical
circle
and
participate
in
online
training
materials
and
go
through
them
together,
so
that
you
are,
you
feel
the
support
of
community
and
you
feel
the
kind
of
engaged.
It's
not
like.
Just
you
learning.
A
A
A
A
We
have
actually
live
webinars
and
on-demand
re
recordings.
So
we've
been
running
a
very
successful
webinar
program
where
we
have
our
members
talking
giving
a
presentation
with
a
very
active
and
engaged
q.
A
on
the
projects
that
they've
been
working
on.
The
thing
that
I
really
like
about
webinars
is
that
they
are
so
interactive.
A
A
We
are
also
really
glad
to
be
launching
a
lot
of
case
studies
and
sharing
real
global
deployments.
We
were
integrated
into
the
deloitte
survey,
where
actually
we
didn't
work
with
deloitte.
They
just
recognized
that
hyperledger
is
a
very
valuable
platform
and
they
have
also
stated
that
blockchain
is
integral
to
organizational
innovation,
so
we
do
hear
a
lot
of
skepticism,
but
on
the
other
hand,
we
are
also
hearing
a
lot
of
positive
around
distributed,
ledger
technologies.
A
So
the
case
studies
that
we
recently
launched
is
one
with
chain
yard
on
trust.
Your
supplier,
that's
a
very
interesting
digital
passport
that
allows
you
to
trust,
to
build
in
trust
into
the
supply
chain.
They
are
now
reusing
it
also
for
looking
at
coveted
credentials
and
trustworthy
commute
along
with
the
case
study,
there's
also
a
recording
of
the
webinar
that
we've
done
with
chain
yard
another
one
that
we
have
launched
is
with
mine
tree.
That's
very
interesting
because
they
did
two
seemingly
very
different
things,
but
actually
they
are
connected.
A
Catalyst
blockchain
is
a
platform
as
a
service
that
supports
deployment
of
hyperledger
fabric
and
accorder
networks
that
has
been
launched
with
intellect
eu,
and
they
have
really
worked
quite
hard
to
create
an
a
project
that
makes
onboarding
incredibly
easy.
We
do
have
actually
an
a
webinar
where
they
also
walk
through
it.
A
Sorry
advanced
innovations
has
been
working
very
hard
on
various
projects.
It's
actually,
I
was
very
excited
when
I
spoke
with
events
and
innovations
lately,
seeing
that
they
have
about
20
projects
that
are
in
production
in
dubai
and
middle
east.
The
one
that
I
really
like
is
the
project
that
they
developed
for
the
well-being
of
small-scale
farmers
and,
overall,
the
development
of
agricultural
sector.
A
It
has
been
launched
in
pakistan
and
collaborates
platform
allows
farmers
to
have
access
to
a
digital
marketplace
where
they
can
conveniently
acquire
relevant
equipment
and
resources
in
a
very
seamless
way.
Then
we
have
ledger
domain
again.
We
actually
have
a
webinar
that
we've
done
with
it.
It's
brilliant,
it's
very
clear,
so
please
do
consider
re-watching
it
if
you
haven't.
This
is
a
around
supply
chain
in
pharmaceutical
industry
and
how
can
we
ensure
that
the
delivery
of
drugs
or
pharmaceuticals
is
trustworthy?
A
Then
there
is
the
other
mind
tree
loyalty
program,
that's
something
that
I
discussed
already
and
yeah.
I
think
with
that.
I
will
pass
over
to
you
peter
so
that
we
can
hear
more
about
cactus,
because
I
think
that's
the
more
important
thing
unless
there
are
any
questions
for
me,
I'm
happy
to
take
questions.
C
C
Okay,
hello,
everyone,
I'm
peter
shomotivari.
I
work
for
accenture
as
an
architect
and
I'm
one
of
the
maintainers
of
the
cactus
project.
It's
a
little
early
here
in
san
francisco.
So
if
I
accidentally
call
cactus
biff,
that's
because
it
used
to
be
called
blockchain
integration
framework
back
when
it
was
just
a
labs
project.
C
So
what
is
it
it
is?
Hopefully
it
will
be
a
plugable
enterprise,
great
framework,
to
transact
on
multiple
distributed
ledgers
without
inventing
yet
another
competing
blockchain.
The
last
part
is
important.
We
do
not
want
a
ledger
of
ledger
sort
of
blockchain,
so
we
do
not
intend
on
having
this
core
functionality
where
we
basically
store
blocks
of
data
and
then
have
some
sort
of
consensus
achieved
on
that
as
part
of
cactus.
C
Everything
happens
so
fast
that
it's
very
difficult
to
keep
up
and
it's
difficult
to
not
have
this
hype
fatigue.
You
know,
and
one
day
you
get
excited
about
some
new
technology,
but
by
next
week
it's
basically
obsolete,
and
then
you
have
to
you
know,
get
excited
again
and
learn
everything
or
not
everything,
but
a
lot
of
things
again.
C
The
number
of
integrations
with
the
number
of
letters
so
for
on
ledgers.
You
need
5000
different
integrations
and
that's
that's
pretty
impossible,
especially
if
you
don't
have
a
framework
to
help
you
with
that,
and
I
wanted
to
show
this
again
and
I
wanted
to
emphasize
that,
even
though
we
are
in
the
tools
category,
one
could
also
make
arguments
why
we
are
more
of
a
library
and
vice
versa.
C
C
So
I
just
wanted
to
clarify
that
make
sure
that
I
mentioned
it
and
then
we
have
a
generic
use
case.
This
is
ridiculously
oversimplified
for
a
reason
I
will
get
into
more
details,
but
I
just
wanted
to
show
this
that
in
the
end,
this
is
what
it
always
boils
down
to.
You
have
more
than
one
letters.
You
know
it
can
be
two
or
ten,
and
then
you
have
a
separate
cactus
deployment
and
the
users
or
the
developers.
C
C
They
almost
always
involve
a
smart
contract
being
deployed
on
the
target
ledgers
to
facilitate
some
sort
of
operation,
for
example,
the
use
case
we
have
with
the
federated
validation,
where
you
can
export
some
data
from
ledger.
A
to
ledger
b
then
have
actual
cryptographic
proof
obtained
from
cactus,
which
obtained
it
from
ledger
aids,
smart
contract,
that
the
data
is
present
on
ledger
a,
and
it
is
indeed
in
the
form
that
ledger
b.
Has
it.
C
C
C
The
main
point
is
that
we
want
to
be
able
to
integrate
with
as
many
lectures
as
possible,
and
we
don't
want
to
limit
ourselves
to
plug-ins
that
we
implemented.
We
want
everyone
else
to
also
implement
targets
secure
by
default
very
important,
it's
one
of
the
boring
ones,
because
nobody
likes
to
deal
with
securing
their
application,
but
we
make
it
a
point
to
have
the
software
come
ship
with
the
security
defaults
that
will
not
cause
any
heartbreak,
hopefully
to
anyone
so
that
it
doesn't,
you
know,
come
deployed
with
a
password.
C
That's
a
admin,
and
the
username
is
also
admin
stuff
like
that,
and
then
we
want
it
to
be
toll-free.
We
do
not
want
any
kind
of
functionality
baked
in
there
that
somehow
ends
up
charging
people,
transaction
fees
or
anything
else.
We
do
not
intend
on
issuing
our
own
tokens
or
have
an
ico.
We
don't
really
want
to
do
any
of
that
low
impact
deployment.
C
C
C
Regardless
of
how
new
or
different
that
ledger
is
because
at
the
heart
of
it
a
distributed,
ledger
is
just
a
database
with
you
know
a
lot
of
extra
bells
and
whistles,
but
in
our
abstraction,
we're
trying
to
just
treat
it
as
a
as
a
read,
write
data
store
that
is
able
to
have
cryptography
proofs
of
the
data.
That's
in
there
and
also
the
smart
contract
support,
which
is
executing
code
for
use
cases
there.
C
C
Preserving
ledger
features.
This
means
that
if,
if
ledger
a
and
ledger
b
are
integrated
with
cactus
for
some
sort
of
business
use
case,
then
we
would
really
love
to
have
as
many
of
the
additional
cool
ledger
features
supported
through
cactus,
as
if
you
were
using
those
ledgers
directly
with
whatever
sdk
or
api,
that
they
provide.
C
C
C
C
C
Some
implementation
details
about
the
project,
much
lower
level.
We
write
the
coding
typescript,
we
bundle
it
with
webpack
and
there's
a
bunch
of
packages.
I
think
it's
already
above
10.,
some
of
them
are
plugins.
Some
of
them
are
the
core
api
definitions.
We
have
an
api
server,
we
have
a
common
package
which
is
designed
to
be
cross-platform,
slash
universal,
so
the
same
package
can
be
installed
in
a
node.js
or
a
browser
environment.
C
C
C
C
C
C
So
that
would
mean
that,
even
though
cactus
is
running
a
node.js,
you
could
write
your
plugin
in
your
favorite
language
and
interact
with
cactus
through
the
localhost
network
interface
and
some
good
ideas
we've
seen
elsewhere.
Implementing
these
is
the
go
plugin
project
which
uses
this
exact
same
mechanism.
C
You
know
package
it
up
as
an
npm
package
and
you're
ready
to
go.
You
can
use
the
plugin.
You
never
have
to
talk
to
any
of
the
maintainers
to
get
any
sort
of
permission
or
any
of
that
and
the
edge
case
is
which
hopefully
will
happen
very
rarely.
But
if
it's
not
even
pluggable
so
this.
If
this
is
something
embedded
in
the
core,
then
we
can
discuss
it
and
if
we
say
yeah,
this
is
a
good
idea.
C
C
And
I
think
I
already
mentioned
this:
preserving
the
ledger
features.
Yes,
yes,
I
already
said
this
I'll
just
skip
this
one,
the
transaction
protocol.
This
is
still
under
design,
but
the
point
is
that
we
want
to
have
this
handshake
phase,
where
both
participants
of
the
transaction
first
have
to
agree
on
what
is
going
to
happen,
how
this
cross
ledger
transaction
is
going
to
be
played
out,
and
that's
the
important
part
about
that,
so
that
nothing
happens,
that
you
don't
want
or
didn't,
anticipate
to
happen
and
the
void
surprise
is
like.
C
C
For
example,
if
if
you
have
a
business
use
case
where
you
want
to
move
large
chunks
of
data
from
one
ledger
to
another
and
both
accounts
or
wallets
or
whatever
identity,
you
have
you
own
both
of
those
on
both
ledgers,
then
you
might
just
want
to
get
it
done
as
fast
as
possible.
Instead
of
having
to
go
through
the
transaction
proposal
phase
for
each
one
individually,.
C
C
The
big
challenge
there
is
that
you
cannot
really
have
any
sort
of
state
or
almost
any
I
mean
we
will
end
up
having
some,
but
we
try
to
keep
that
to
the
minimum,
because
that's
what
always
bulks
software
down
where
when
it
has
to
store
a
certain
amount
of
state,
so
we
intend
to
be
stateless
wherever
possible
and
that's
that
actually
ties
back
twice.
What
I
said
about
us
not
wanting
to
store
blocks
of
data
and
be
responsible
for
the
consensus
and
all
that.
C
This
is
a
more
complicated
version
of
a
use
case
that
I
wanted
to
show.
This
is
in
our
white
paper
and
I'm
not
going
to
explain
it
in
in
great
detail.
It's
really
just
to
show
that
we
do
have
details.
I
promised
them
in
the
beginning
on
that
very
oversimplification
slide,
and
you
should
definitely
check
out
the
white
paper
that
we
have
on
github
within
the
github
repo,
because
there's
lots
of
this.
C
C
So
the
point
there
is
that
you
can
verify
you
can
give
a
verification
to
one
letter
that
a
certain
state
is
on
the
other
ledger
for
a
specific
block
or
a
piece
of
data,
and
we
want
it
to
be
fill
stock
tolerance.
So
if
one
node
goes
down
or
if
a
member
of
your
consensus
goes
down,
then
it
shouldn't
stop
working,
it
should
just
handle
it.
C
C
That's
where
requests
come
in
from
a
client
application
and
the
on-chain
logic
is,
as
it
is
right
now.
Most
of
the
time
is
a
smart
contract
that
we
deployed
on
the
ledgers
that
we
support
and
really
what
the
off
chain
logic
does
is
invoke
the
on-chain
logic
to
work
its
magic
and
deliver
the
specific
use
case
that
you
wish
it
to
do.
C
We
do
have
a
roadmap,
but
this
is
heavily
subject
to
change.
We
want
to
finalize
the
1.0
design
and
the
technical
architecture
we
do
not
yet
have
a
1.0
release
or
a
stable
version
of
it.
I
wanted
to
reiterate
that
and
regarding
identity,
we
want
to
support
all
the
cool
solutions
out
there
and
standards.
C
I
am
personally
a
big
fan
of
the
sovereign
foundation
and
I
also
have
been
working
on
editing
some
sort
of
open
id
connect,
support
for
identities,
but
that's
also
still
work
in
progress.
If
you,
if
you
want
the
absolute
hardcore
details,
there
is
a
pull
request
open
with
it,
and
the
project
so
feel
free
to
check
that
out
as
well.
C
Implementing
plugins
for
different
languages
mention
that
consortium
management.
I
talked
about
that
and
we
definitely
want
some
sort
of
first
public
test
deployment
that
would
achieve
some
sort
of
dummy
hello
world
use
case,
but
out
there
in
the
public,
so
that
everyone
can
give
it
a
test
and
see
it
in
action.
C
A
C
Well,
if
you
are
looking
to
contribute
the
plugin
to
the
main
repository,
then
it
will
be
scrutinized
by
all
the
maintainers
heavily,
so
that
is
sort
of
an
approval
process,
but
you
can
also
develop
your
own
plugins
and
nobody
stops
you
from
publishing
those
and
divide
open
internet
and
nobody
will
stop
people
from
using
it.
So
there
isn't
at
the
moment
a
sort
of
a
safeguard
around
us,
except
maybe
a
verbal
recommendation
that
if
you
operate
cactus,
then
you
should
not
install
plugins
without
reviewing
the
source
code.
C
And
if
someone
is
trying
to
obfuscate
the
source
code,
then
that's
obviously
a
red
flag,
but
yeah.
I
think
that's
a
that's
a
great
point,
that's
something
we
should
look
into,
because
this
could
be
a
problem
just
like
it
is
a
huge
problem
with
the
app
stores,
the
main
stream
app
stores.
Where
you
know
a
big
big
percentage
of
the
apps
out.
There
are
basically
just
malware.
A
C
There
is
a
an
api
proposal
out
there
right
now
in
the
examples
directory
of
ours
where
it
is
proposed
that
we
should
have
an
event-driven
way
of
listening
to
changes
in
the
ledger
state
so
that
you
as
a
an
end
user,
slash
developer.
You
can
subscribe
to,
let's
say
a
certain
block
or
a
certain
transaction
being
completed
on
one
or
both
of
the
ledgers
or
all
of
them,
and
then
you
get
notified.
C
B
I
mean
if
we
have
a
few
different
networks
of
participants
that
do
not
intersect
with
each
other,
but
they
have
different
instances
of
cactus
that
want
to
connect
to
each
other,
for
example,
if
it
would
be
something
like
an
oracle
that
tells,
I
don't
know,
exchange
rates
for
different
currencies
and
one
organization
would
want
to
interact
with
another
organization's
instance.
Is
this
something
to
consider,
or
all
interactions
are
only
within
blockchains?
B
C
C
So
in
theory,
if
you
want
an
application
that
doesn't
just
work
with
one
cactus
deployment,
but
also
an
other,
you
could
do
that
and
the
experience
in
the
code
should
be
largely
the
same.
You
just
have
to
be
aware
of
the
differences
of
those
two
cactus
deployments.
For
example,
you
know
one
of
the
deployments
will
have
a
ledger
connector
plug-in
for
fabric,
but
the
other
one
will
be
for
basic,
so
you
have
to
take
care
of
that
in
your
code,
but
other
than
that
it
should
just
work.
That's
my
personal
vision
of
this.
C
We
do
plan
on
supporting
ethereum,
you
know
just
because
something
is
proof
of
work.
It
doesn't
mean
that
we
cannot
integrate
with
it.
It's
just
that.
I
will
work
extra
hard
on
telling
everybody
and
making
sure
that,
if
you're
integrating
with
a
proof-of-work
pleasure,
then
certain
things
can
happen
that
are
outside
of
your
control.
A
Awesome
yeah
that
that
makes
total
sense.
So
I
think
that
well
do
the
the
people
have
more
questions.
We
have
still
some
time
if
you'd
like
to
you,
know
grill
me
or
peter
on
any
topics
we're
here
for
you
really
so
I'll.
You
know
give
you
a
minute
to
to
think.
If
you
have
any
questions
and
if
you
don't,
then
we
can
always
just
wrap
up.
B
B
C
C
Yes,
but
there's
a
there's
a
fine
print
there,
which
is
that
you
can
only
guarantee
this
if
you
are
transacting
with
ledgers,
where
both
of
those
ledgers
are
under
your
control,
in
the
sense
that
you
can
actually
do
a
rollback
right,
because
you
cannot
roll
back
a
proof
of
work
lecture,
but
the
two-phase
commit.
I
really
like
that.
A
Yep,
I
was
just
waiting
giving
people
a
moment,
but
I
think
we
are
done
here.
This
was
amazing,
as
clive
says,
it's
a
great
good
presentation
and
good
answers.
I
would
say
it's
great
presentation
and
great
answers.
I
am
really
appreciative
because
I've
had
so
many
people
asking
about
cactus
and
learning
more
about
it,
so
it
will
be
awesome
to
also
be
able
to
point
people
at
the
recording
of
this
presentation.
