So
hi
everyone
and
thank
you
for
finding
the
time
to
joining
us
today
and
welcome
to
today's
virtual
hyperledger,
meetup
five.
As
you
might
know,
bird
chain
is
now
organizing
the
hyperledger
berlin
meetup
and
presenting
interesting
use
cases
coming
from
the
hyperledger
ecosystem
every
three
months.
If
you
are
interested
in
presenting
any
use
case,
please
get
in
touch
with
us.
I
will
be
posting
shortly.
A
C
C
Today,
I
want
to
talk
about
the
cs3
project,
which
the
project
funded
by
the
horizon
2020
program
from
the
european
union,
and
what
is
it
all
about?
It's
a
research
and
assessment
project,
interestingly
focused
on
disruptive
technology.
So
the
key
question
was:
what
can
destructive
technology
do
for
the
or
how
can
the
public
administration
use
these
technologies
to
well
create
new
services,
or
maybe
also,
how
could
the
new
role
of
public
administration
look
like
with
this
new
technology
support?
C
What
can
they
enable,
and,
together
with
that,
there
was
in
the
initial
grant
agreement
quite
some
systems
with
a
lot
of
complexity
designed
here,
as
you
can
see,
there
are
a
lot
of
different
stakeholders,
like
association,
local
retailers,
the
public
administration,
but
also
a
lot
of
different
technologies.
So
blockchain
was
not
only
one,
it
was
just
was
not
the
only
one
was
combined
with,
for
example,
augmented
reality
or
interactive
democracy
like
delegated
voting
systems,
and
in
addition
to
that
also
with
the
new
form
of
while
exploring
geolocated
social
networks.
C
Of
course,
during
the
project,
the
pandemic
happened
and
well
act.
Actions
in
the
physical
space
became
very
difficult
and
very
restricted
in
a
lot
of
regions,
but
we
tried,
as
during
the
project,
to
stay
as
close
as
possible
to
this
idea.
Okay,
how
can
we
use
the
scarcity-
and
this
is
also
one
of
the
core
functionalities
of
blockchain
system
in
this
project
and
where
we
use
hyperledger
meso
to
do
this
mapping
of
the
scarcity
of
the
physical
space
and
give
it
a
digital
representation.
C
Of
course,
we're
not
the
only
partners
in
this
project,
we
have
three
cities
as
partners,
so
the
city
of
essence,
the
city
of
turin
and
paris
that
are
running
different
pilot
sites
and
trying
to
well
explore
these
technologies.
And
then
there
are
different
technical
partners
like
flexi,
guided
for
the
interactive
democracy
and
delegated
voting
mechanisms,
ap
unit
as
a
blockchain
partner,
together
with
the
university
in
turin
and
geomotion,
who
create
the
augmented
reality,
interfaces.
C
So
we
had
a
couple
of
user
facing
components
like
the
wallet
together
with
the
deep
link
format,
as
you
saw
before,
there
are
really
lots
of
different
moving
parts
in
this
project,
and
one
of
the
key
requirements
is
creating
a
relatively
open
system
that
can
be
used
in
very
many
different
ways
and
different
pilot
sites.
So
we
really
try
to
create
more
like
universal
building
blocks
that
can
can
can
work
for
the
blockchain
network
itself.
C
We
used
to
improve
of
authority
network
click,
consensus,
a
couple
of
smart
contracts,
for
example,
for
crowdfunding
activities
and
similar
things,
and,
of
course
well.
Blockchains
are
great
for
storing
mutual
data,
but
well,
not
very
good
in
retrieving
the
data
fast
and
in
a
way,
as
other
applications
needed.
So
we
also
created
a
tailored
middleware
layer
to
allow
us
access
to
the
data,
and
in
addition
to
that,
we
also
start
a
research
track
more
focusing
okay.
What
would
happen
if
these
pilots
would
run
on
a
bigger
scale?
C
C
C
Later
on
may
be
usable
can
can
be
reused
in
other
projects
and
something
so
that
also
well.
Hopefully,
someone
can
make
use
out
of
this,
and
we
that
goes
a
bit
in
the
similar
direction.
Also,
we
want
to
have
the
flexibility
and,
of
course,
also
the
licensing
in
the
horizon.
2020
project
was
what
was
also
key
and
fast.
C
Where
are
we
right
now,
so
the
technical
development
is
pretty
much
finished
and
the
first
pilot
site
still
with
corona
starting
in
april,
so
we're
super
curious
how
things
are
gonna
be
used,
and
what
I
want
to
focus
today.
A
little
bit
about
is
what
are
our
learnings
for
that.
So,
first
of
all,
well
with
cyberledger
best,
was
really
well
pretty
good
to
work
with
and
was
a,
I
think
for
us
a
good
base,
and
we
never
regretted
this
decision
to
go
set
to
go.
C
But
I
think
for
me
personally,
the
most
interesting
part
was
on
working
in
a
research
project,
because
before
we
are
very
much
like
our
background,
is
very
much
product
driven
and
always
go
in
delivery,
making
release
and
so
on.
So
this
was
working
with
universities
and
cities
and
the
public
administration
really
quite
a
change
for
us
as
a
development
and
implementation
team,
and
then
I
think
the
second
part
that
was
really
interesting
was
about
the
impact,
so
also
this
project
was
structured
as
a
kind
of
technology
project
to
explore
these.
C
These
different
technologies-
I
think
one
of
the
biggest
impacts
is
or
will
be,
is
how
also
the
mindset
in
the
public
administration
can
change
while
looking
at
these
technologies
and
what
what
they
can
enable-
and
I
think
this
is
one
of
the
key
aspects,
and
what
was
next
to
that
also
really
interesting.
Is
that
the
most
of
the
let's
say,
technical
development
work
was
really
building
user
interfaces
that
don't
need
blockchain
addresses
to
do
transfers
and
connect
with
all
these
different
services
that
are
already
there
or
that
other
partners
have
built.
C
Yeah,
I
think
that's
it
for
people
who
want
to
learn
more
there's
the
project
website.
There's
a
long
read
blog
article
going
really
into
the
details
of
also
this
idea
of
mapping
the
star
city
and,
of
course,
at
the
university
of
turin,
you
can
find
some
more
information
about
the
blockchain
research
that
is
carried
out
there
and
last
but
not
least,
you
can
also
get
in
touch
with
me.
A
D
You
mentioned
that
one
of
the
goals
of
the
project
was
to
to
change
the
the
mindset
of
the
public
administration
with
regards
to
blockchain
and
technology,
and
I
mean
that's
something:
we've
been
trying
to
to
do
on
a
large
scale.
So
what
what
would
you
say
was
the
the
impact
that
or
the
aha
moments
or
whatever
like
that?
That
came
up.
C
I
saw
this
more
as
one
of
the
things
that
happened
really
in
this
well
exploration,
phase,
that
there
was
really
the
the
space
of
re-thinking
the
role
of
public
administration
from
well
shifting,
maybe
a
little
bit
from
being
the
administrative
buddies.
It's
doing
administration
and
administering
the
public
goods
towards
becoming
an
enabler
building
the
tools
for
the
people.
They
need
to
manage
the
communities,
the
public
goods-
and
this
was,
I
think,
one
of
the
most
interesting
parts
for
me
to
well
be
involved
in
this
process
and
see
this
happen
and
yeah.
D
D
A
E
Hi
guys,
yes,
thank
you
for
for
having
this
session
very
interesting.
Both
emails
talk
and
presentation
and
the
project
I'm
coming
from
industry,
and
you
know
we.
We
are
working
with
games
and
you
know
we
are
working
with
some
companies
that
are
considering
nft
as
one
of
the
use
cases
for
integrating
within
their
gaming
communities,
and
I
was
wondering
if
you
guys
have
any
views
on
how
hybrid
laser
could
facilitate
those
type
of
use.
Cases.
C
Well,
I
can
as
a
quest
for
me.
I
can
only
answer
from
my
let's
say,
very
personal
experience
of
you.
I
think
there
currently
a
lot
of
interesting
use
cases
around
nfps
explored.
We
are
also
working
on
the
on
the
project
within
the
well
that's
targeted
towards
the
music
industry,
since
we
have
a
very
large
network
there
already
from
from
previous
projects.
C
C
Well,
maybe
for
for
a
lot
of
use
cases,
the
need
to
well
to
use
different
networks
and
in
terms
to
to
address
the
scalability
right,
if
you
use,
for
example,
nfps
to
kind
of
keep
keep
track
of
things
or
nfps
that
own
nfgs
then
change
them
into
each
other,
and
so
on.
You,
you
get
to
a
point
where
you
have
a
lot
of
transactions
and
might
also
want
to
create
a
network.
E
So
let
me
give
you
like
a
typical
example
of
one
of
our
customers.
I
don't
know
if
you
are
familiar
with
the
8th
ballpool
from
miniclip,
so
they
have.
Typically,
I
mean
those
guys
are
from
the
largest
games
in
the
industry.
They
have
like
500
million
downloads
and
you
know
all
their
users
play
april.
You
know
online,
so
you
know
pool
tables.
As
you
know,
they
have
a
lot
of
grow.
You
know
a
lot
of
ideas
of
how
to
personalize
items
around
the
game.
E
You
know
you
have
virtual
librarians
right
now
they
don't
have
enfts.
You
know
they
don't
have
personalized
content
that
someone
owns
but
effectively
if
they
would
create
some
sort
of
a
market
for
content
creators
to
create
new
content
items
that
were
consumed.
The
potential
customer
base
would
be
500
million
so
that
you
know
I
don't
know
how
that
would
translate
on
daily
transactions.
E
But
you
know
it
comes
with
quite
a
large
volume.
So
I
was
wondering
I
mean
you
know
there
is
definitely
some
some
aspects
of
compliance,
because
most
of
those
games
need
to
be
distributed
by
official
stores.
So
there's
you
know
the
aspect
of
having
something
which
is
compliant
with
those
stores,
but
let's
say
that
this
is
a
policy
discussion
when
you
select
your
technology,
whether
it's
public,
whether
it's
a
private
laser
that
you
know,
one
of
these
organizations
have
have
set
up
already
for
them
and
used
as
a
service.
E
C
Well,
I'm
not
sure
if
I'm
the
best
person
to
answer
this
question,
maybe
also
someone
who's
more
familiar
with
hyperledger
fabric
is
pretty
suited
for
that,
because
I
mean
within
the
hyper
ledger,
project
they're
different
subprojects,
and
some
of
them
are
maybe
more
suitable
than
others
right,
so
I
mean
in
the
project
I
presented
here
today.
We
well
the
network
architecture
was
relatively
simple
to
what
else
we're
doing,
also
in
terms
of
requirement
from
towards
a
transaction
volume
that
can
be
processed
since
it
was
targeted
for
this
pilot
size.
C
Well,
I'm
not
sure,
as
I
said,
but
what
we're
currently
or
what
we're
looking
at
doing.
This
project
that
I
just
presented
was
how
can,
for
example,
the
aggregation
of
bls
signatures,
help
with
different
blockchain
networks
to
maybe
combine
transactions,
and
so
on
to
well
make
the
the
right
operations
in
the
end,
you
need
on
the
public
network
less
and
still
enable
user
interactions,
the
one
one
of
the
paths
to
go.
There
are
a
lot
of
different
technologies
to
to
address
these
scaling
issues.
A
D
D
B
Well,
I'm
definitely
interested
in.
I
know
we
have
well
here
just
to
share
if
people
are
interested
in
what's
going
on
with
blockchain
and
climate,
I
will
point
out
that
here
hyperledger
has
a
climate
action,
an
accounting
special
interest
group,
and
so
I
know
we
shared
this
presentation
with
this
group,
and
I
know
we
have
some
people
from
that
group
here
today.
B
Uh-Huh
exactly
so,
hyperledger
has
a
number
of
different
special
interest
groups
that
are
around
adopting
how
blockchain
technologies
are
being
adopted
in
different
industries,
and
so
climate
is
one
also.
We
have
one
a
media
related
one
that
the
topic
of
nfts
came
up
earlier.
So
we
have
a
media,
entertainment
group
and
they
just
recently
had
a
presentation
of
using
hyperledger
to
create
a
digital
collectible
tool.
So
if
people
are
interested
in
just
how
blockchain
is
being
applied
in
different
industries,
I'll
drop
a
link
to
our
special,
our
all
the
special
interest
groups
that
we.
B
A
B
F
Okay,
yeah,
I'm
really
sorry
just
when
I
wanted
to
start
to
turn
on
my
my
camera
soon
crashed.
So
I
don't
know
why
why
this
happened
and
then
I
couldn't
even
stop
zoom.
I
had
to
reboot
my
whole
laptop
and
it's
currently
running
up
again,
so
it
shouldn't
be
too
much
longer.
I
really
apologize,
but
I
I
don't
know
how
this
could
happen.
It's
actually
never
happened
to
me
before
so.
F
We
founded
circular
tree
in
2018
and
really
our
target
was
to
support
companies
in
getting
more
sustainable
supply
chains,
and
we,
we
initially
started
with
a
project
in
the
area
of
conflict
minerals
and
did
a
pilot
project
there
with
daimler
and
then
and-
and
this
is
quite
interesting
with
email.
We
also
got
an
opportunity
to
join
in
in
a
research
project
which
is
called
block.
Three
and
block
three
is
really
a
health.
C
F
But
it's
also
a
consortium
together
with
a
technical
university
with
the
research
center
informatic
with
university
of
karlsruhe
with
the
charity.
So
it's
all
together,
10
partners
and-
and
I
can
kind
of
confirm
what
emil
was
also
saying-
that
it's
really
interesting
to
to
look
at
projects.
From
from
this
perspective,
where
you
don't
really
are
not
just
looking
and
getting
something
out,
but
where
you
really
do
some
research
and
in
that
project,
for
example,
we
were.
F
Doing
a
thorough
investigation
of
many
different
blockchain
types
before
we
finally
decided
to
use
hyperledger
fabric
so
and
I'm
very
excited
to
see
that
this
will
eventually
be
realized
and
I'll
be
more
than
happy.
Maybe
in
a
year,
if
we
have
something
running
to
to
show
you
some
details
about
this
as
well.
So
now
I
should
be
coming
up
with
my.
F
B
B
F
F
F
F
F
Okay,
okay,
news
new
start,
so
I
was,
I
was
just
just
to
finish
this
with
with
a
block
three
project.
It's
quite
interesting
to
to
learn
other
things
and
in
the
block
three
thing
is
that
we're
only
working
on
the
blockchain
layers,
so
everything
above
is
done
by
other
partners.
So
we
can
fully
focus
on
on
the
blockchain
part
and
do
not
need
to
have
much
domain
expertise
out
of
the
healthcare
area
that
just
for
for
a
starter.
F
F
F
The
big
problem,
however,
is
the
product
carbon
footprint
so
typically,
and
and
this
is
an
investigation
by
the
carbon
disclosure
project,
the
last
company
only
adds
20
carbon
footprint
to
a
product.
80
comes
through
the
supply
chain
and
there
you
have
the
challenge.
There
is
no
visibility
these
days
about
the
carbon
footprint
of
the
supply
chain.
F
If
companies
are
providing
product,
carbon
footprint
information,
it's
done
by
a
life
cyclist,
they
virtually
take
their
product
apart
and
then
check
it
out
in
databases
and
and
take
average
data
to
calculate
it.
But
this
does
not
address
the
problem
because
it's
not
a
real
carbon
footprint
and
you
cannot
really
change
something.
F
How
does
it
work
very
simple,
for
example,
this
is
a
project
we've
done
with
startup
autobahn,
so
basf
as
a
chemical
company
provides
a
granulate.
They
write
the
product
carbon
footprint
of
the
granulate
on
the
carbon
block
system.
Then
you
add
the
transportation
of
the
granulate
to
motherson,
who
is
a
tier
one.
Supplier
making
bumpers
motherson
takes
the
carbon
footprint
of
the
granulate,
and
then
they
add
what
it
takes
them
to
make
a
bumper
and
this
total
carbon
footprint
they
ride
again
on
carbon
block.
F
We
add
transportation
again
and
then
you
they
do
this
with
all
their
suppliers
and
add
their
own
carbon
footprint
for
making
a
tycoon.
Then
they
have
a
real
carbon
footprint
of
a
tycoon,
and
this
is
a
basic
architecture
of
what
we're
using
it's
a
little
bit
simplified
because,
of
course,
real
supply
chain.
Look
much
different,
but
at
the
end
of
the
day,
is
the
important
thing
product
carbon
footprint
from
one
tier
to
the
next.
F
Is
what's
important
about
the
solution?
Is
that
you
need
to
automate
this,
because
companies
have
way
too
much
products
in
order
to
manually
calculate
this,
so
you
need
an
architecture
where
you
can
have
databases
providing,
for
example,
the
bill
of
material
production
process
data,
and
then
you
only
need
to
set
up
once
a
process
model,
and
then,
if
one
of
your
suppliers
changes
his
product
carbon
footprint,
the
system
then
can
automatically
calculate
the
new
value.
F
F
F
This
is
some
more
detailed
architecture,
I'm
I'm
not
a
software
architect
so,
but
if
you
have
any
further
questions,
do
young
is
also
on
to
call
he
can
answer
those
questions
now,
once
we
have
the
transparency,
you
want
to
do
something,
and
this
is
a
great
thing
you
can
have,
for
example,
product
comparisons.
You
can
compare
different
materials
and
say:
okay,
this
material
too,
has
a
lowest
carbon
footprint.
F
F
It
helps
to
determine
the
best
levers
to
reduce
product
carbon
footprint
and
it's
very
important
to
have
automated
processes
for
data
collection
and
transfer,
and
it's
one
standard
one
tool.
The
efficiency
between
customer
and
supplier
increases
significantly
and
in
regards
to
blockchain
what
the
feedback
was
is.
F
If
people
know
data
is
immutably
stored
on
the
system,
they
feel
that
companies
have
a
greater
accountability
for
data
reliability.
So
it's
a
psychological
thing
that
that
they
really
say:
okay,
if
it's
immutable
stays
there
forever
and
cannot
altered
they,
they
believe,
there's
a
greater
accountability.
F
After
we,
we
did
this
project,
we
were
invited
by
the
world
business
council
development,
they
had
just
started
a
similar
project
and
this
is
called
sos
1.5
for
yeah.
We
need
to
to
achieve
the
1.5
degree
from
the
paris
climate
agreement
pathfinder
project,
and
this
project
approach
is
exactly
the
same
as
we
did
it
and
jose
invited
us,
because
we
had
already
done
a
pilot.
What
is
now
what
is
now?
F
F
And
in
my
last
slide
you
see
they've
also
they've
also
monetarized.
This.
This
was
on
an
example
of
a
large
large
foods.
Many
fast
moving
goods
manufacturing
company
in
a
five
to
tier
ten
years
time
frame,
but
they
think
it's
one
to
two
percent
of
the
revenue
could
be
avoided
offsetting
spend
if
they
have
a
lower
carbon
footprint.
They
need
to
pay
less
carbon
tax,
and
this
could
add
up
to
two
percent
of
the
revenue
top
line
growth.
F
Those
companies
in
there
say
that
they
have
sustainable
product.
Sustainable
products
grow
faster,
and
then
they
see
a
top-line
growth
of
one
to
three
percent
and
then
in
the
reporting
they
say
they
could
achieve
a
saving
of
up
to
five
million
per
year,
and
this
is,
in
my
opinion,
very
important
that
we
not
only
have
the
savings
of
carbon
footprint,
which
is
of
course
very
important
for
society
and
for
the
planet,
but
that
also
companies
can
have
a
benefit
by
this.
And
then
we
will
see
that
there
is
a
much
quicker
adoption.
F
A
Thank
you
gunther
for
the
presentation.
Actually,
I
can
see
why
you
you
used
hyper
ledger
fabric.
I
mean
because,
for
the
proof
of
authority
algorithm,
it's
definitely
fast
and
energy
efficient.
I
actually
have
a
question
regarding
so
carbon
block
actually
enables
all
participants
to
share
actual
carbon
footprint
information
in
the
supply
chain.
F
A
F
D
D
This
company
makes
a
part
what
about
multi-multi-tier
supply
chains
like
if
you,
if
you
take,
for
example,
palm
oil,
sometimes
like
palm
oil
refinery
sources
from
200,
different
meals
and
then
a
chemical
company
sources
from
three
different
refinery
and
uses
a
refined
palm
oil
to
put
it
into
20
different
products
that
are
then
used
again
by
companies
into
50
different
different
products.
So
there's
a
non
many-to-many
relationship
does
it
does
it
also
work
in
in
those
cases.
F
F
One
is
a
standardization
of
the
calculation
rules
and
this
is
exactly
what
you
are
addressing
if
I
have
multiple
inputs
and
multiple
outputs
which
output
gets,
how
much
of
the
of
the
carbon
footprint
and-
and
this
is
where
we
are
making
rules
on
how
companies
need
to
calculate
this
or,
for
example,
if
a
company
purchases,
like
whatever
eighty
percent
power
from
coal
and
twenty
percent
renewable,
do
they
know
which
value
can
they
say?
Okay,
twenty
percent
they
make
zero
carbon
products
and
the
other
80
is
is
getting
all
the
carbon
footprint.
D
Yeah,
so
this
means
that
like
if
we,
if
we
again,
I
don't
know,
take
the
example
of
palm
oil.
If
you
have,
for
example,
a
company
buys
one
ton
of
like
very
good
sourced
palm
oil
and
200
kilos
of
badly
sourced
palm
oil.
We
can
calculate
like
an
average
kilo
of
palm
oil
that
is
used,
has
this
carbon
footprint
and
then
on
the
other
side,
when
they
use
it
in
their
products.
You
would
say
if
you
use
out
of
this
1.2
tons
like
500
kilos,
then
you
you
take
like
this.
F
Yes,
this
is
exactly
this
is
exactly
the
discussion
which
is
going
on
right
now
and
probably
we
will
allow
we
will
allow
both.
However,
it
needs
to
be
absolutely
ensured
that
not
more
of
the
of
the
good
palm
oil
is
calculated,
then
is
there
is
in
reality.
You
know
this.
This
will
definitely
need
to
be
ensured,
but
probably
we
will
allow
companies
both
options.
It's
not
final
yet,
but
this
is
what
what
I
think
will
will
be
the
outcome.
D
F
Maybe
then
I
have
one
one
last
comment
for,
because
it's
just
a
hyperledger
meeting
and
and
I've
I've.
I
see
that
robin
is
here.
We've
also
started
discussions
and-
and
I
I
think
this
is
a
really
great
opportunity-
also
for
hyper
ledger-
with
robin
from
the
special
interest
group
climate
action
to
see
whether
whether
we
can
cooperate
here
in
developing
open
standards
based
on
hyper
ledger
fabric.
So
this
is
certainly
something
which,
which
I
think
would
also
be
great.
B
Yeah
robin,
do
you
want
to
say
a
word
or
two
about
the
group?
Yes,
thanks
gunther.
Yes,
we
are
the
hyperledger
climate.
Sick
david
also
said
that
before
we
have
bi-weekly
meetings
every
tuesday,
so
we
have
a
meeting
on
tuesday
at
I
think
it's
6
p.m.
Central
european
time
you
all
haven't
invited.
We
are
currently
developing
an
hyperledger
lab.
I
will
share
the
link
with
you.
It's
based
on
appalachia
fabric
and
we
also
use
an
ethereum
implementation
for
the
trading
with
carbon
emissions.
Tokens
so
be
all
invited.
B
D
A
A
D
C
A
D
Be
just
as
a
quick
heads
up,
we
will
be
running
this,
probably
on
a
quarterly
basis.
So
if
you
have
any
interesting
use
cases,
stephanie
already
mentioned
it
but
reach
out
to
us
from
from
birching,
and
then
we
can
see
how
and
when
we
can
accommodate
any
any
presentations
in
the
in
the
upcoming
hyperledger
meetups
so
feel
free
to
drop
us
a
message
and
then
and
get
in
touch.
