A
Meeting
we
are
now
recording
okay.
Thank
you.
Thank
you,
though,
for
reminding
me
for
that.
So
for
today's
meetup,
I
would
like
to
keep
it
short
and
very,
very
focused
so
for
our
agenda.
We
shall
just
have
some
quick
introductions
and
then
we
shall
recap
the
system
that
we
that
we
are
modeling
from
last
time.
A
That
is
just
go
over
the
notes
and
then
see
what
what
we
missed,
what
we
had
right
and
then
from
there
we
shall
convert
that
that
design,
that
concept
into
the
hyperledger
fabric
architecture,
and
here
we
shall
be
assisted
by
by
umafool
and
then.
Lastly,
we
shall
scope
out
the
work
that
can
that
can
be
done,
because
it's
possible
to
scope
to
have
everything
like
designed,
but
then
it
can
be
difficult
to
implement.
So
we
shall
have.
A
A
A
A
Okay,
let's
say
that
we
have.
We
have
okay,
maybe
just
to
to
go
a
bit
lower.
We
have
landlords
and
property
owners
who
actually
own
the
property,
but
for
blockchain
system,
not
all
of
them
can
afford
to
have
like
a
peer
that
is
able
to
that
is
able
to
to
compute
and
believe
those
records
for
themselves.
So
you
find
that
in
most
places
you
find
that
there's
an
organization
and
maybe
they've
come
together
to
say
that
this
is
our
group
which,
under
which
we
are
to
champion
for
our
right.
A
A
They
are
able
to
validate
records
as
a
single
peer
as
opposed
to
each
and
every
landlord
having
their
own
their
own
appear.
So,
ideally,
the
property
owners
are
the
ones
who
see
who
the
land
is
registered
under
and
then,
if
somebody
wants
to
buy
or
sell,
they
have
to
ensure
that
proper
records
for
that
particular
piece
of
real
estate
that
they
want
to
buy.
A
And
then
we
saw
that
there
might
also
be
some
users
somewhere,
like
let's
say,
if
I'm
looking
for
a
piece
of
property
or
I'm
looking
for
a
piece
of
land,
I
am
a
buyer.
So
our
name,
if,
if
it's
a
property
I
want
to
see
in
which
here
was
our
property
built
the
type
of
foundation.
I
saw
that
in
some
countries
that
matters
the
type
of
wood
that
was
used
to
build,
that
particular
property.
A
A
That
was
let
me
like
one
bit
of
it
and
then
next
we
have
a
appeal
which
was
suggested
was,
but
if
you
want
to
purchase
a
piece
of
land,
there
is
always
a
need
to
finance.
So
you
also
want
to
like
figure
out.
How
can
I
pay
for
this
particular
piece
of
land?
Do
you
want
to
be
a
bank
insurance
and
all
those
things?
A
So
those
those
are
a
suggestion
to
have
like
banks,
maybe
as
a
peers,
to
be
to
be
able
to
assist
in
the
area
for
the
area
of
financing
and
then
yeah
if
they're
getting
alone,
I
like
you
want
to
know.
I
don't
want
to
be
like,
like
sure,
I
want
to
confirm
that
the
loan
was
for
this
amount
and
the
interest
for
a
particular
loan
left
alone
that
you
took
to
pay
for
the
piece
of
a
piece
of
land
and.
C
D
C
D
A
C
D
A
A
Yes,
so,
and
so
from
there
on,
you
find
that
there
is
yeah
the
proper
records
for
loans
and
interest
that
are
supposed
to
be
paid
for
that
particular
piece
of
land,
depending
on
how
you
want
to
finance
that
piece
of
that
piece
of
land
and
then
next.
Another
pier
was
a
is
the
element
of
regulation,
so
you
want
to
so.
The
government
always
has
to
be
involved
in
like
land
issues,
for
for
the
focus
and
purpose
of
watch
of
things
like
taxes
and
yeah
taxes
and
ownership.
A
So
you
find
that
if
you
don't
pay
tax,
the
government
can
take
ownership
of
your
land
and
even
sell
your
property
at
an
auction,
and
then
the
government
like
determines
who
is
the
legal
owner
of
a
piece
of
that?
This
set
all
the
disputes
for
a
particular
piece
of
land.
So
it's
only
fair
for
them
to
have
a
peer
that
they
can
be
able
to
perform
regulation
over
and
then
therefore,
those
element
of
insurance.
E
A
B
B
B
B
C
B
C
C
B
B
I'm
on
linux,
linux
and
the
application
is
dia
like
diagram,
okay,
okay,
so
the
blockchain
network
is
a
property
of
the
government
and
the
buyers
and
owners
are
here
so
in
the
in
the
scope
of
the
appellation
fabric.
I
will
share
with
you
or
will
read
with
you
the
documentation
I'll
show
it
here.
So
maybe.
B
B
B
B
Regulatory
or
some,
maybe
the
government
make
some
operation.
Maybe
the
government
have
control
over
the
fees
the
the
insurance
company
is
making
on
the
buyers
on
the
selling
activities,
so
that
is
the
private
communication
and
the
buyer
and
owner
does
not
have
doesn't
have
to
to
to
participate
in
those
negotiation
and
transaction
and
there
in
another
channel
inside
the
same
blockchain
imperative
fabric
blockchain
network
in
another
channel.
B
C
B
B
B
C
B
Okay,
so
the
second
channel
is
just
for
the
peers
of
the
bank
and
of
the
insurance
company.
We
will
not
talk
about
them
for
now.
We
will
do
it
at
a
later
time
before
we
finish,
we
are
coming
back
to
them.
So
all
those
these
groups
and
channel
and
communication
device
are
inside
the
blockchain.
The
network.
C
B
B
C
C
C
A
B
B
D
B
C
B
B
C
C
C
B
B
C
B
D
Bit
beyond
that
directs
inheritance
or
mapping
from
what
the
inheritance
does,
what
government
and
those
right
now
manually
and
first
of
all,
like
you,
said,
government
owns
our
land.
You
know
in
a
territory,
so
there's
some
kind
of
mapping
exercise.
I
think,
there's
something
called
the
cadastral
map
based
on
some
of
the
ways.
D
E
D
E
D
A
D
D
I
don't
know
what
they're
called
are
they
called
gis
boundaries
or
something
like
that?
You
know
so,
for
instance,
over
here
in
nigeria,
plots
have
a
specific
size
and
they
are
bounded
by
geographic
beacons,
right
so
yeah,
so
sometimes
they
may
be.
They
may
be
four
four-sided.
You
know
they
may
not
necessarily
be
a
rectangular
square,
but
they
are
usually
bounded
on
four
sides.
D
How
how
big
the
land
should
be
on?
So
that's
what
I
can
say.
So
I
don't
know
what
subset
of
all
the
powers
that
the
government
has
in
an
offline
setting,
I'm
currently
enjoying
today.
What
subset
of
those
powers
do
we
want
to
enable
in
our
network
that
can
then
help
inform
rights
you
want
to
give
them
this
network.
B
B
D
B
I
don't
think
so,
because
I
I
maybe
in
this
second
part
the
government
take
back
ownership
of
the
properties
if
the
tax
aren't
paid
can
be
represented
here
in
some
self-assignment
of
a
property.
If
the
man
can
come
and
say
the
this
previous
belonging
to
abu
milah
now
belongs
to
the
government
of
nairobi,
africa,
kenya,
so
it
is
a
process
of
taking
it
back.
B
A
B
E
C
B
C
Our
last
meeting
we
were
talking
about
taxes.
I
guess
it
was
a
standpoint
of
does
the
is
that
information
that
our
transactions
that
apply
to
the
land?
So
if
the
government
like
when
they
assess
the
tax
for
that
year
on
the
land,
was
that
information
that
the
buyer
wants
to
see
associated,
you
know
with
the
land
and
if
the
taxes,
you
know,
if
the
what
the
taxes
were
so
for
decision
making
a
lot
of
people,
look
at
that
as
a
factor
like
what
are
you?
C
What
are
what
I'm
looking
at
as
far
as
one
of
my
pack,
property
taxes
typically
are
going
to
run
me,
and
so
that's
I
don't
know.
If
it's
a
this,
it
could
be
considered
a
transaction
on
that
particular
entity,
because
you
know
that
this
it's
a
it's
an
assessment
and
whether
or
not
it's
you
know
whether
or
not
it
even
if
we
don't
even
mark
whether
or
not
it
was
actually
paid
or
what
have
you
but
the
information
that
goes
along
with
the
property.
C
B
B
But
the
government
is
the
one
who,
because
the
land
belongs
to
him,
the
government
is
the
one
who
will
validate
the
transaction
because
of
it
is
an
automatic
mechanism,
because
maybe
we
don't
want
people
to
know
some
some
some
some
kind
of
because
of
privacy
or
some
some
type
of
consideration
like
that.
You
don't
want
to
know
if
I
have
paid
all
my
tax,
because
it
is
something
private.
I
don't
want
people
to
know.
B
B
B
D
E
E
D
E
C
E
So
from
the
government
and
as
as
you
said,
we've
all
agreed
that
everything
starts
with
the
government
and
ends
with
the
government.
So
the
owner
is
the
is
the
government
with
the
the
cadestrial
registration
and
stuff
that
takes
place.
Okay,
then,
in
between,
when
the
government
is
the
first
movement,
or
I
can
say
the
first
transaction
from
from
government
to
any
entity.
D
E
E
E
C
D
E
Yes,
yes,
so
they
are
there.
Yes,
they
will
create
and
they
will
lease.
Yes,
exactly.
That's
a
government,
okay,
yeah!
Oh
they
can.
They
can
also.
There
is
a
there,
is
a
possibility
of
also
now
I'm
not
sure
about
the
terms,
but
if
they
want
to
take
back
the
any
property
I
don't
know,
they
also
contradict
for
the
english
speaking
guys.
C
E
B
You
can
be
sure
there
are
plenty
of
of
of
consideration
in
land
creation
and
losing
and
ownership
and
transfer
and
all-
and
just
since
we
are
only
technical
guy
here
we
are
trying
to
do
our
best,
and
maybe
after
speak
this,
let's,
let's
roll
okay,
so
the
owner
are
just
can
just
sell
properties.
I
don't
see
what
what
can
they
do
after
that?
B
B
B
C
C
C
C
C
B
B
B
You
cannot
send.
You
cannot
sell
a
property
before
you
have
it
and
that
the
the
and
that
information
can
can
come
from
the
date
of
the
of
the
leasing
or
of
the
buying
or
of
the
land
allocation
by
the
government
or
someone
else.
So
the
order
is
the
first
piece
that
come
into
the
into
the
the
the
blockchain
the
fabric
blockchain
network.
C
B
E
E
B
B
C
B
B
B
B
Because
there
is
some
different
type
of
land
property
learn
land
title
in
french?
We
have
a
second,
what
we
call
theater
frequency
and
by
I
don't
know
the
english
four
of
those.
So
if
you
have
some
type
of
land
title,
you
cannot
resell
it
or
it
isn't
some.
It
is
something
that
you
have
to
to
precise,
so
our
data
associated
with
land
are
very
rich,
so
we
have
to
use
a
database
which
that
we
can
we
can
that
can
reflect
the
richest
of
of
our
data.
B
B
It
is
a
network
which
is
going
to
be
very,
very
solicited
solicited
by
the
citizens,
because
there
will
be
it
at
the
same
price.
It
is
it
there
will
be
plenty
of
reading
activity.
Like
I
see
I
saw
a
property
and
I
want
to
know
to
which
guy
it
belongs
to,
and
then
we
have
some
other
privacy
concern
like
do.
B
B
C
B
C
C
B
C
C
C
C
C
B
B
C
E
B
E
I
agree
with
you
at
some
up
to
some
extent,
but
the
concern
that
our
colleague
is
just
raised
there
as
to
do
mainly
with
when
we
say
certificate
authority
on
our
technical
understanding.
We
understand
that
this
is
the
system
I
mean,
if
I
could
say
so,
the
guy
behind
all
the
technical
setup
and
all
that,
but
we
have
to
put
in
mind
that
this
entity,
this
certificate
authority
entity
and
be
a
part
of
the
government,
but
now
in
our
modeling
process.
E
Here
I
guess
that's
how
umar
is
is
looking
at
his
now
modeling
part
here,
the
certificate
authority
regarding
a
private
company,
or
is
it
part
of
the
public
services?
It
remains
as
us
as
a
different
entity
in
the
whole
modeling
that
we
are
doing
here.
It
can
be
private,
it
can
be
public,
but
it
has
to
be
a
separate
entity.
I
think
that's
how.
C
E
C
E
E
E
Not
obviously
set
up
an
example
could
be
an
example
could
be
in
in
some
countries.
You'll
find
this
certificate
authority.
Is
the
ministry
actually
of
land,
okay
and
and
under
the
ministry
of
land?
You
could
have
the
I.t
department
that
manages
maybe
this
this
network.
So
in
that
case
that
I.t
department
or
the
ministry
of
lands
become
the
certificate
authority,
okay
or.
E
B
B
That
those
identity
card
have
a
ship
in
in
them
which
which
have
some
kind
of
signature
of
the
government.
Maybe
in
we
can
find
a
system
where
we
can
use
the
identity,
the
ship
inside
the
identity
card
to
identify,
identify
ourselves
that
will
be
our
certificate
certificate
and
that
is
already
signed
by
the
government,
because
I
think
I'm
not
sure
they
have
done
it
themselves,
but
there's
something.
That
is
something
that
exists
already,
that
we
can
manage
to
use.
B
C
D
C
D
D
I
just
have
a
question
to
ask,
and
perhaps
coco
landry
hinted
at
that
earlier:
did
everyone
did
everyone
flow
along
with
with
the
session
you
know,
did
it
make
sense?
That's
that's
what
I'm
getting
at.
Do
we
all
flow?
These
are
the
questions
in
general.
How
do
we
enjoy
it?
Did
we
flow?
Was
it
meaningful
or
was
it
cryptic
and
programmable
and
geek
speak.
C
D
D
D
Mindsets
to
the
development
of
of
sorting
in
such
such
a
service,
where
I'm
going
is,
there's
an
there's,
an
exercise
that
I
like
to
carry
out.
Usually:
okay,
it's
an
it's
on
top
of
the
design
thinking
process.
Sometimes
you
know
it
can
be.
It
can
be
seen
as
something
like
a
game
actually
all
right
where
we
we
allow
everyone
to
see
how
technical
teams,
ideally
technical
teams,
ideally
build
products
first,
before
committing
a
line
of
code
on
to
the
code
base,
how
they
build
product
concepts.
B
D
D
D
So
the
questions:
what
should
we
buy?
What
should
we
build?
Why
should
we
build
it
and
for
whom
should
we
build
it
right?
Design?
Thinking
helps
us
answer
those
questions.
Okay,
the
second
question:
how
should
we
build
one
to
build?
Now
I
mean
I'm
a
proponent
of
the
agile
agile
methodology,
and
you
know
it's
attending
benefits
somewhere
in
here
is
where
blockchain
falls
in,
because
blockchain
is
an
approach,
is
a
is.
D
It
is
a
functional
approach
to
the
functional
approach
among
many
alternatives
to
achieving
an
envelope
right
again,
if
you
think
about
it
critically
concerning
scope,
the
blockchain,
technically
speaking,
is
meant
to
provide
some
kind
of
back
service
to
a
product
right.
So
you
would
all
you
would
have
that
somewhere.
You
know
in
your
architecture
that
you
did
today,
you
know
and
so
on
and
so
forth.
D
Third
question
is:
how
should
we
see
icd
develops
you
know
and,
and
that
whole
new
pattern
of
so
so
this
is
like
a
high
level
product
development
process
that
I
use
for
both
my
clients
and
my
internal
product
visa
product
development
company
shooting
out
shooting
out
from
this.
I
then
have
like
I
said
that
exercise
that
we
carry
out
where
we
learn
how
to
map
features
in
our
hands.
D
D
So
if
you
take
any
of
these,
for
instance,
so
so
there
are
three
ques,
there
are
four
questions
answered
by
this
process.
What
should
we
note,
why
should
we
build
it
and
for
whom,
should
we
build
it
kind
of
kind
of
kind
of
kind
of
think
of
those
three
questions
as
sub
of
one
you
take
them
together
as
one
understand.
The
second
question
is
how
okay
and
the
third
is.
Third,
is:
how
should
we
release
first
question?
Is
how
should
we
deal
with
second
third
questions?
D
I've
worked
with
I
used
to
be.
I
used
to
be
a
hands-on
programmer
back
in
the
days
when
there
was
no
distinction
between
backing
up
front
and
like
like
these
young
developers
of
nowadays
I
enjoy
so
much
back
in
the
days
when
javascript
had
only
one
flavor,
it
was
vanilla
javascript,
there
was
no
search.
Well,
there
were
two
there
was.
There
was
vb
script
back
in
the
days
that
microsoft
was
trying
to
push,
but
javascript
was
javascript.
You
know.
D
You
know
so
so
so
so
so
I've
I've
both
been
a
a
a
a
hardcore
coder
and
I've
worked
closely
very
very
closely
with
hardcore
coders.
You
know
amazon,
technical
people,
and
I
can
tell
you
that
many
times
we
techies
we
deep
minded
people
sometimes
fall
into
the
trap
of
building
technology
for
the
sake
of
technology.
So
sometimes
we
might
have
a
fantastic
product
idea
and
we
start
to
build
it
or
we
start
to
get
immersed
in
it
mentally.
But
somewhere
along
the
line
we
get
carried
away
with
the
technology.
D
I
started
this
with
laravel
2.0,
but
level
2.5
has
come
out.
Online,
2.1
or
242
has
come
out
and
there
are
these
new
features
and
I
suddenly
feel
that
those
features
you
know
I
must
include
them
in
the
new
game,
and
I
start
to
worry
about
technology
for
getting
that
at
the
end
of
the
day,
when
I
use
a
2.0
like
a
7.0
or
I
use
python,
3.6
or
python
2.7,
I
use
net
core
or
use
dot
net
4.5.
D
D
Channel
the
spirit
or
the
essence
of
our
users,
you
know
come
out
of
ourselves
and
and
look
at
problems,
problem
species
and
their
potential
solutions,
potential,
alternative
solutions
from
the
light
from
the
perspective
of
the
users
who
will
use
those
solutions
at
the
end
of
the
day
now,
design
thinking
of
itself
started
off.
As
you
know,
a
movement
or
as
as
as
a
very
narrow
space
or
has
become,
you
might
call
a
family
of
techniques
nowadays.
D
So,
if
you,
depending
on
the
organization
you're
talking
to
almost
every
organization,
has
a
flavor
of
design
thinking
sap
has
a
slightly
different
flavor
from
the
ibm
model,
the
p
model,
the
r
commodore
you
know,
all
of
them
have
tweaked
the
generic
model
and
create
their
own
kilometers.
However,
what
what
you
can
take
away
from
it
are
two
key
aspects
or
goals.
One
of
them
is
a
research
aspect,
and
the
second
is
the
design
and
and
and
those
two
things
are
logical
steps
start
with
that
same
order.
D
D
If,
if
you
can't
afford
it,
like,
I
said,
just
sit
down,
observe
them
observe
their
their
everyday
stresses
their
everyday
disappointments,
their
everyday
frustrations
as
well
as
their
everyday
highs,
all
of
those
things
and
then
design
something
that
does
not
take
away
from
their
from
their
from
that
and
from
their
positive
moments,
but
eliminates
their
negative,
their
negative
moments.
You
know.
So
so
that's
essentially
what
this
is.
D
Of
course,
when
you
break
it
down,
you
get
the
business
goals
section
where
you
start
out
by
defining
what
the
business
goals
are
and
the
and
the
end
result
of
that
process
is
something
called
the
business
model,
canvas,
okay
and
a
list
of
business
goals,
and
you
define
the
personas.
So
who
are
the
people
that
try
to
achieve
these
goals?
D
D
What
are
their
personality
types
attitudes
challenges
and
then
you
end
with
a
question,
is
usually
in
innovation
circles:
they're,
usually
upgraded
to
hmw's
hmw's
stands
for
it
stands
for
how
might
tweeze
okay
and
how
my
tweet
is
a
template
that
that
is
a
template
question
that
innovators
used
to
say
after
on
this,
after
after
researching
into
a
particular
persona,
to
understand
those
people's
challenges
and
needs,
you
then
ask
how
much
we
help
them
eliminate
this
goal.
How
much
will
help
them
sustain
this
positive
aspect
of
in
what
they're
currently
doing?
D
The
second
step
set
of
step
steps
is
a
further
breakdown
and
a
further
elaboration
of
the
first
set
of
goals,
so
the
second
time
first
set
the
first
set
of
goals
you
defined
are
business
goals
for
the
team
organization
or
for
the
business
unit.
This
second
time,
you
are
identifying
individual
goals
for
each
of
the
personas
that
you
defined
in
step
two,
so
you
pick
each
of
these
guys
and
you
define
a
specific
set
of
goals
that
those
guys
want
to
achieve.
D
So
when
you
have
that
set
of
goals,
you
then
define
the
journey
or
the
set
of
steps
that
each
of
those
users
must
take
to
achieve
that
goal,
and
by
doing
that,
you
automatically
have
something
called
a
story
map.
Let
me
quickly,
let
me
mark
this
point
and
quickly
share
another
screen
with
us.
That
shows
an
example
story
map,
obviously
we'll
be
able
to
do
that
today,
but
I
just
want
to
want
to
show
so
that
I
can
so
I
can
have
somewhere
to
start
off
in
the
next
session.
D
Yes,
okay,
now
this
is
a
now.
This
is
a
product
that
I
love
very
much
stories
on
board
if
anybody
has
been
been
part
of
a
story,
mapping
exercise
before
which
is
typically
a
very
hands-on
physical
exercise
where,
in
an
office
space,
you
have
a
wall
that
you
dedicated
for
your
product
or
for
your
project,
and
it
has
sticky
notes
that
you
stick
in
a
particular
pattern
on
that
wall
that
represent
the
breakdown
of
work
items
for
that
particular
work.
So,
if
I
were
to
take,
if
I
were
to
take.
D
D
D
So
you
notice
that
up
until
now,
we
all
of
this
is
high
level
use
case,
slash
user
story,
modeling,
okay,
and
it
helps
us
because
further
down
the
line
in
terms
of
achieving
consensus
on
what
needs
to
be
built
in
terms
of
achieving
consensus,
on
the
priority
of
things
to
build
in
terms
of
achieving
consensus
on
how
much
to
what
technical
depth
each
of
those
items
needs
to
be
implemented.
In
other
words,
what's
the
trade
off?
D
What's
the
trade-off
for
technical
debt
that
we
want
to
take
all
of
those
decisions
that
happen
that
we
are
bringing
together
while
doing
storing
up?
And
then
you
have
your
empathy
maps,
you
know,
which
are
also
a
part
of
the
personal
definition
and
then
the
end
result
of
the
entire
result.
Research
phase
is
an
idea
prioritization
grid,
okay,
which
this
which
helps
us
map
or
compare
ideas
for
their
possible
fit
for
suitability.
D
D
It
will
be
voted
higher
than
a
low
impact,
high
effort
idea,
you
know,
and
so
on
and
so
forth.
We
can
follow
that
up
with
designs.
At
that
point
again,
before
committing
to
code,
we
are
committing
to
defining
what
the
user
interfaces
might
look
like.
Don't
forget
this
is
the
research
and
design.
So
this
is
still
part
of
that
user.
End
user,
immersion
phase
of
the
project,
where
we're
seeing
the
user's
environment
and
we're
designing
screens,
that's
unsettling.
How
am
I
doing
so
that
by
the
time
we
have
sketches
those
screens
low?
D
Five
stands
there
for
low
fidelity.
High
fives
to
hair
stands
for
high
frequency.
Low
five
means
things
that
are
sketched
out.
You
know
usually
a
very,
very
high
level
of
a
very,
very
low
level
of
detail,
so
you
can
either
you
can.
Actually,
you
will
use
your
pen
on
paper
or
a
tissue,
or
some
kind
of
like
like
to
say
restaurant,
restaurant
tissue
or
service
or
something
and
take
a
picture
of
that
and
that's
low
five
welcome.
That's
fine
enough!
D
You
know
it's
good
enough
to
start
too,
and
then
you,
if,
if
you,
if
you
have
an
approval
on
on
the
low
five,
you
then
graduate
to
the
high
five
okay.
At
this
point,
you
don't
have
enough
to
start
to
think
about.
You
have
enough
enough
enough
detail
enough
validation,
which
is
more
important.
It's
more
about
validation,
you're,
not
validation,
to
start
to
think
about
the
how
until
we've
answered
the
questions
of
what's
why
and
for
whom?
D
If
sometimes
it
usually
doesn't
make
sense
to
start
to
think
about
how
okay,
so
when
we,
when
we
then
get
to
that
in
here
somewhere
in
this
process,
is
where
our
blockchain
development
fits
into
the
overall
architecture
of
the
solution?
Okay,
because
at
the
end
of
the
day
the
blockchain
will
expose
to
us
a
set
of
apis,
usually
rest
apis
that
can
be
consumed
by
the
front
end
of
our
application
right
and
then
that's.
That's
what
this
entire
section
is
about,
so.
D
With
iterative,
agile
development,
sometimes
you
can
skip
the
business
case
if
you've
done
a
good
job
with
the
upper
level.
You
know
and
the
product
vision
as
well,
but
what
you
really
really
want
to
do
here.
You
want
to
start
with
your
story
map
which
we
would
have
seen
a
few
moments
ago
before
the
next
meeting,
I'll
make
sure
that
my
account
is
back
up.
You
choose
which
add-on
framework
you
want
to
use.
I
like
something
called
the
scrum
band,
which
is
a
hybrid
of
scrum
and
kanban
frameworks.
D
You
know
and
that's
that
you
define
a
working
agreement,
define
your
squads
and
so
on
and
so
forth.
So
so
that's
basically
what
this
is.
The
rest
is
just
operational
stuff
and
we
are
almost
out
of
time.
Okay,
but
can
we
can
we
drop
it
here
and
agree
to
pick
it
up
from
the
story?
Mapping
session
that
I
was
not
able
to
show
us
to
and
we
agreed
from
there
for
the
next
meeting.
A
Thank
you
very
much
for
that
about
the
leverage
session
on
how
to
go
about
design
thinking.
So
I
believe
we
can
stop
there
for
today
and
then
for
the
next
meeting.
We
can
pick
it
up
from
here
and
then
determine
just
who
are
we
building
this,
for
so
that
you're
not
just
building
it
for
the
sake
of
using
blockchain
or
because
you
are
because
you're
a
hyperledger
meter,
so
we
can
stop
there
and
then
we
shall.
B
E
Okay,
okay!
Well,
this
is
coco.
This
is
my.
I
did
attend
one
of
the
first
chat
sometime
back,
but
not
the
the
first
chat
regarding
the
design
of
the
solution
that
you're
working
on
my
point,
I
just
wanted
to
clarify
a
few
things
before
we
close
off.
We
building
this
as
just
a
use
case
for
the
group
to
get
to
understand
how
the
hyperledger
platform
works.
Is
that
the
case.
E
I
guess
yes,
yes,
that's
the
approach.
Okay.
That
said,
I
think
we
will
have
if
we
are
really
looking
at
having
a
solution
that
responds
to
the
needs
of
them
of
of
the
market.
If
I
can
say
that
we
will
have
to
consider
having
on
board
someone
who
really
understands
the
the
old
setup
that
has
to
do
with
with
real
estate
and
land
management
and
all
that,
because
if
we
start
from
a
very
shaky
shaky
ground,
I
know
definitely
you
can
have
a
prototype,
but
it's
just
my
point
of
view.
E
A
E
A
So
I
believe
that
is
the
end
of
the
meeting.
So
I'd
like
us
to
do
one
more
thing.
I
forgot
to
do
the
intros
as
you're
starting
so
for
this
last
bit.
I
would
like
all
of
us
to
turn
on
our
videos
and
then
we
can
see
our
names
and
what
we
do
as
they
close
the
meeting
and
also
also
I'd
like
to
give
a
word
of
thanks
for
david
devrick
has
been
with
us
for
all
the
meetups
ever
since
we
began.
So.
Thank
you
derek.
A
A
C
A
C
E
E
So
we,
my
interest
in
hyperledger,
is
mainly
with
there's
a
we
we're
working
currently
on
an
application
that
could
at
some
point
look
into
leveraging
on
the
blockchain
technology,
so
we're
still
assessing
which
platform
is
best
fit,
and
there
was
no
better
place
than
this
forum
to
to
get
faster.
You
know
understanding
of
the
technical
side
of
what
it
takes
to
build,
at
least
a
minimum
prototype
that
you
know
guys
could
interact
with
yeah
and
so
far
I
can
say
that
I'm
in
the
right
forum
thank.
E
C
C
C
C
A
C
A
A
B
Of
senegal,
so
I
am
a
french
speaker,
we
are
doing
activities
in
french
most
of
the
time,
but
I
recently
joined
miller
in
the
in
this
in
this
adventure.
If
I
can
call
it
that,
because
it
is
very
interesting-
and
it
is
a
very,
very
acute
problem
we
have
here
in
africa,
so
it
is
really
a
pleasure
to
join
you.
My
main
interest
in
blockchain
technology
are
in
the
decentralized
identity.
C
C
I
have
traveled
to
I
traveled
to
uganda
two
years
ago,
and
that
was
an
amazing
trip.
It
was
my
first
time
ever
to
africa
long,
but
it
was.
It
was
a
great
experience
and
I
was
thinking
about
you
know
with
technology,
and
now
you
know
just
having
the
ability
to
just
be
a
part
of
this
group
is
truly
amazing.
You
know
I
would
you
never
would
have
thought
that
you
know
be
able
to
work
on
a
project
with
you
know
those
so
far
away
from
you
and
I
take
pleasure
in
it.
C
C
C
C
B
B
B
C
B
D
All
right,
so
my
name
is
edu,
though,
is
three
syllables
and
five
words,
which
is
very
strange
because
that's
a
very
high
number
of
syllables
for
the
number
of
letters,
so
I
usually
give
anybody
outside
nigeria.
The
shortcuts
just
take
the
first
two
letters
id
and
ignore
the
rest.
Id
has
been
my
nickname
since
childhood.
D
D
D
D
The
businesses
are
their
business
outcomes.
They
think
that
I
can
think
out
with
developer
brains.
So
I
I
coach
developer
teams
nowadays,
that's
what
I
do
so,
I'm
more
focused
nowadays
on
the
product,
slash
business
side
of
technology,
solutions
ensuring
that
the
tech
teams
produce
the
business
outcomes
as
intended
rather
than
building
technology.
Like
I
said
earlier
for
the
sake
of
technology,
so
that's
who
I
am
my
particular
interest
in
hyperledger-
is
slightly
romantic,
but.
D
D
You
know
quote-unquote
other
paradigms,
so
that
development
paradigms
take,
for
instance,
systems
that
have
been
built
on
anti-architecture.
You
know
relational
database
architecture
and
so
introducing
blockchain
will
naturally
be
met
by
some
kind
of
resistance
in
africa,
because
you
know
partly
due
to
corruption
and
other
forces.
Those
systems
do
not
exist.
Perhaps
we
are
the
best
people
to
introduce
web
3.0
blockchain
and
if
you
think
about
the
space
of
blockchain,
the
global
space
which
of
the
blockchain
framework
for
ecosystems,
is
business
ready
from
day
one
from
the
moment
to
pick
it
up.
D
Is
the
business
ready
for
business
ready
for
enterprise,
because
they're
ready
for
government
institutions?
That's
hypocrite.
I
mean
compared
with
any
of
the
others,
and
you
naturally
come
to
that
conclusion.
That
hyperledger
is
is
ready
for
business,
almost
ready
for
deployment
from
day
one
you
know
so
so
that's
so
that's
how
I
got
here
and
together
with
umar
and
mila,
we
coordinate
actions
for
hyperledger
across
the
african
continent.
I
am
based
in
nigeria.
I
work
with
an
another
gentleman
called
uchena
and
together
we
run
the
nigeria
chapter
as
well.
A
Why
I
meant
to
hyperledger
is
a
as
though
was
mentioned:
it's
a
business
oriented
blockchain
as
opposed
to
others
like
ethereum
and
and
and
bitcoin,
which
are
more
crypto
and
which
people
muslims
like
see
us
fraud
so
like
this
is
a
it
is
more
for
business
and
it
can
be
quote-unquote
privatized
as
opposed
to
like
other,
like
other
blockchains.
So
that
is
why
I
am
there
and
also
I
I
used
one
of
the
products
for
a
finally
a
project,
and
I
believe
it
actually.
A
It
did
like
it
didn't
go
well,
because
it
was
a
blockchain.
At
the
same
time
it
was
limited
to
who
can
actually
access
it.
So
that
is
my
interest
in
in
blockchain
and
as
we
do
was
mentioned
for
africa,
you
find
that
this
is
the
issue
of
lack
of
systems
for
accountability.
So
I
believe
we
are
at
a
good
place
to
be
able
to
introduce
such
systems
yeah,
so
that
is
that
is
it
on
my
end.
