Description
Approach, Experiences and Reflections - Imre Kocsis, Budapest University of Technology and Economics
During the last year, our research group began to gather experience in blockchain education. We concluded our first university blockchain course in “Blockchain technologies and applications” (with 200+ students and numerous alumni), ran multiple industrial courses and successfully applied for online course development at a major European industrial consortium.
The talk discusses our approach towards Blockchain education that emphasizes distributed ledger and integration platform aspects, in a technologically balanced way - the introduced platforms range from Hyperledger Fabric/Composer to Ethereum. The course presents in-depth the different alternate distributed ledger solutions and principles in the Hyperledger project; an important aspect is the overview of the entire blockchain development lifecycle, covering the Hyperledger ecosystem and the application know-how of its individual elements. We provide a broad overview of application patterns, from middleware through cooperation to tokenization.
The talk is an overview of the didactic strategy, complemented by the experiences based on the feedback from our audiences and practical problems solved by them.

A
Yes,
we're
in
Switzerland,
let's
begin
sharp,
okay
welcome
everybody,
I'm
Morocco,
Josh
I'm,
an
assistant
lecturer
at
the
Budapest
University
of
Technology
and
economics
in
Hungary,
Budapest
I'm,
with
the
Department
of
measurement
and
information
systems.
There
and
I
will
talk
about
teaching,
blockchain
the
University
students
and
professionals,
approach,
experiences
and
reflections,
so
a
form
of
question
how
many
people
from
academia
here-
oh
okay,
yeah!
This
will
be
one
of
my
points
trying
to
talking
to
your
audience
for
the
other
people.
I
hope
it
will
be
still
worthwhile
to
hear
this
talk.
A
This
will
be
about
mostly
experiences
and
how
we
approach
teaching
blockchain
so
not
about
the
corpus.
The
subject
material
per
se.
I
hope
that
that's
okay
with
you
so
who
we
are
in
a
bit
more
detail
inside
the
department.
We
are
the
fault-tolerant
systems,
Research
Group,
that's
pretty
close.
The
blocks
changed
block
chains
founded
by
Professor
Potter.
A
It's
a
and
the
whole
research
group
is
20
people
strong,
but
these
are
the
key
people
working
on
blockchain
right
now,
the
whole
field,
the
whole
direction,
was
bootstrap
by
2016
IBM
faculty
of
word
awarded
to
Professor
Potter
it.
So
that
was
still
back
in
the
days
of
fabric
version
0.6,
when
the
code
was
the
documentation,
documentation
was
the
code,
so
that
was
the
early
time.
We
did
performance,
modeling
and
analysis
in
cooperation
with
Duke
and
based
on
our
efforts
in
this
topic
and
others.
A
We
are
very
proud
to
have
become
an
associate
academic
member
of
hyper
ledger.
We
did
a
hyper
ledger.
Internship.
There
was
a
mentor
and
mentee
at
us,
one
of
the
key
maintainer
zuv
caliper,
the
performance
measurement
tool
is
dead,
guy
dare
with
the
Bears
osceola
I,
do
work,
I
hope
rather
actively
in
the
performance
and
skill
other
group
led
by
Mark
there
and
and
we
also
participate
in
the
training
and
education.
We're
a
group
which,
as
I,
see
I,
speak
mostly
to
academic
people.
A
I
encourage
everybody
to
at
least
check
out
it's
worthwhile
on
the
one
hand,
and
on
the
other
hand
we
do
need
the
people
I'm,
also
a
national
delegate
to
the
blockchain
Technical
Committee
of
ISO,
and
that's
that
so
a
really
short
disclaimer.
These
will
be
our
own
experiences.
We
are
an
engineering
school,
mostly
computer
engineering
and
electrical
engineering
faculty
with
strong
computer
science
people,
but
that's
not
the
focus
of
the
faculty.
We
have
our
own
geography,
we
have
our
own
industrial
environment
and
also
this
whole
talk
will
be
quite
opinionated.
A
That's
super
interesting
and
chances
are
that
what
your
audience
knows
is
still
that
Bitcoin
thing
and
how
that
works,
and
when
this
mismatch
is
present,
then
what
comes
through
is
well
it's
situational.
What
comes
through,
but
my
first
ever
real
TV
interview
didn't
really
go
down
that.
Well,
the
constant
seems
to
be
that
you
have
to
make
sure
that
this
is
understood
and
by
this
I
mean
the
distributed,
ledger:
technologies
concept.
You
have
a
peer-to-peer
or
quasi
peer-to-peer
network,
that's
doing
small
database
or
smallish
database
synchronization.
A
But
the
network
is
some
sort
of
consensus
over
the
transactions
and
the
blocks
only
serve
a
batching
mechanism
and
there
are
different
honesty,
incentives
across
networks.
These
vary.
On
the
one
hand
we
have
fabric
at
all
with
pbft
and
whatnot
no
funny
money
needed.
On
the
other
hand,
we
have
Bitcoin
and
the
other
health
coins,
where
you
need
as
an
economic
incentive,
the
presence
of
a
cryptocurrency
and
what
we
try
to
do
is
trust
disintermediation.
A
We
did
this
work
in
our
own
performance
and
scale
working
group
to
whole
cost
spent,
with
hashing
out
the
core
concepts
and
defining
those,
and
the
same
happened
in
standardization
bodies
too.
But
by
today
this
is
more
or
less
covered.
See.
For
instance,
the
NIS
see
internally
report
a
202,
that's
very
nice
or
check
out
our
performance,
metrics
white
paper.
That's
out
really
nice,
and
maybe
you
should
give
it
a
read.
So
there
are
three
key
challenges
across
the
board.
There
seem
to
be
three
key
challenges
across
the
board.
A
When
you
teach
blockchain
one
is
there's
always
there
seem
to
be
still
always
a
fat
factor
that
you
have
to
cope
with,
or
my
take
is
actually
that
is
not
the
fear,
uncertainty
and
doubt
that
you
have
to
manage.
Rather,
you
have
to
disperse
confusion
and
doubt
so
you
have
to
drive
in
that.
This
is
a
multi-party
DB
and
openness
and
the
funny
money
may
not
be
required
it
may
be,
but
deciding
about
it
should
be
a
conscious
and
opinionated
analytic
effort
and,
on
the
other
hand,
fear
and
uncertainty
may
be
justified.
A
Who
has
seen
hyper
Ligeti
NOLA,
there's
a
little
more
fly,
creature,
eating
your
fabric
and
there's
where
the
name
comes
from
so
at
Def,
Con
26,
a
really
good
research
group
did
present
ways
and
ways
and
ways
to
break
a
hyper,
larger
fabric.
Network
and
those
are
very,
very
fun
Boveda
does
it.
This
doesn't
mean
that
fabric
is
rubbish.
A
This
means
that
if
you
don't
configure
it
properly,
it
will
be
breakable
and,
on
the
other
hand,
when
you
intend
these
networks
to
be
immutable
and
everlasting
almost
everlasting,
then
these
become
really
serious
questions
and
you
have
to
pose
the
question
whether
you
can
justify
the
value
and
is
your
incentive,
adversary
or
model
right.
These
have
to
be
addressed,
but
this
fear
and
uncertainty
factor
is
something
else
than
simple
doubt
and
confusion.
You
have
to
disperse
the
confusion
and
doubt
and
reason
rationally
about
the
actual
risks.
A
The
way
that
we've
always
been
doing
second,
is
that
yeah,
you
have
to
stay
on
your
toes.
So
although
the
speed
of
evolution
in
the
whole
blockchain
sphere
seems
to
have
slowed
down
a
bit,
the
domain
is
still
evolving
quite
fast,
so
the
distributed
DB
synching
is
settling
in
what
we
see
now
is
actual
applications.
Privacy,
deployment
governance
see
yesterday's
keynote
from
Accenture.
A
It
was
very
good,
in
my
opinion.
Still
you
have
to
be
really
at
the
bleeding
edge
still
and
that's
not
always
easy,
and
the
key
challenge.
Number
three
is
that,
in
my
opinion,
you
should
get
people
back
to
earth-2
at
the
beginning
of
any
engagement.
Most
of
these
blockchain
stuff
can
be
explained
in
simple
terms,
from
Bitcoin
to
hyper
ledger,
not
oversimplifying
what
I
mean
is
factually
and
when
you
present
the
facts,
what
a
network
system
can
do
and
what
it
can
do,
instead
of
all
the
astroturf
finger,
the
dreams
that
what
should
it
do?
A
Then
people
calm
down
and
begin
to
think
rationally
and
yeah
falling
BTC
price
on
the
end
of
the
ico.
Grace
may
have
actually
helped
out.
So
speaking
in
specifics,
what
should
we
teach?
My
first
premise
is
that
you
can't
Beach
all
this.
This
is
simply
impossible
and
you
shouldn't
even
do
that.
This
is
a
nice
infographics
from
Black,
Moon
crypto,
and
what
I
use
it
for
is
to
demonstrate
that
this,
the
whole
blockchain
sphere
is
still
a
pretty
much
intractable
problem.
A
You
certainly
can
teach
the
classic
academic
stuff
consensus
mechanisms
or
what
we
have
been
doing
for
two
years:
performance
measurement
and
analyzes,
or
the
specifics
of
non-deterministic
Byzantine
filter
application.
This
is
a
really
good
paper,
I
like
from
Kishan
and
bucolic,
but
the
question
is
whether
you
should
teach
this
so
one
of
our
own
results,
if
you
like,
is
a
first
stab
at
a
educational
design,
space
for
blockchain
education,
it
seems
to
be
so
that
there
are
sure
the
core
technologies
and
data
models
and
the
algorithmics
at
the
foundation.
A
So
this
is
the
computer
science
stuff.
On
top
of
that,
there
are
the
platforms
and
frameworks
say:
hyper
larger
networks,
deployment
operations,
integration
overlays,
including
lighting
network,
and,
like
so
overlays
in
the
broad
sense.
On
top
of
that,
when
you
have
all
these,
you
can
speak
about
transformative
applications,
patterns
of
cooperation,
say
putting
the
supply
chain
on
the
blockchain
or
if
we
are
at
that
any
work
flow,
and
this
is
something.
Lastly,
my
colleague
will
talk
about
in
this
room
in
the
afternoon.
A
You
will
want
to
have
solution,
design
methodologies.
You
will
want
to
have
approaches
to
if
I,
existing
solutions
and
processes,
and
on
top
of
that,
you
will
want
to
think
about
the
socio-economic
and
environmental
impacts
of
the
technology.
You
will
have
to
have
regulation
legislation,
policymaking,
there's
market
engineering,
government
investment
and
the
premiership,
there's
all
sorts
of
dimensions.
A
You
can
approach
the
blockchain
sphere
from
so
actually
from
an
educational
point
of
view,
you
have
an
optimization
problem
where
you
have
to
choose
from
these
boxes
and
somehow
come
up
with
a
path
that
makes
sense
for
your
audience
inside
the
subset
of
boxes
that
you
chose
notice
that
most
of
these
topics
can
be
mapped
to
types
of
people
that
will
apply
that
body
of
knowledge.
So
this
is
mostly
core
computer
science,
Computer
Engineering,
Computer,
Engineering
and
system
engineering,
analysts
domain
experts
and
at
the
top
we
have
decision
makers
and
public
servants.
A
Now
the
problem
with
blockchain
is
twofold:
most
of
these
boxes
are
still
evolving
emerging.
What
we
have
at
the
bottom
that
seems
to
settle,
or
at
least
the
evolution
it
seems
to
slow
down
and
exactly
as
we
heard
from
Accenture
now,
the
focus
is
shifting
upward
and
upward
and
upward,
because
when
you
have
a
fabric,
that's
nice,
but
you
have
to
have
operations.
What
do
we
do
when
we
have
to
upgrade
the
software?
It's
still
not
that!
A
Well
answered
and
when
you
have
answered
those
questions
you
will
have
governance
questions
like
what
do
we
do
when
the
whole
database
is
bored
and
the
oldest
consortium
have
to
roll
the
thing
back?
So
this
is
where
you
have
to
pick
and
choose
from,
and
there
are
further
dimensions.
This
can
be
further
divided
by
technology
and
the
Kliq
application
domains,
making
a
full
pyramid
of
the
thing.
But
then
we
would
come
seriously
close
to
business
science,
and
that's
that's
not
us.
So
what
I
can
speak
about
as
specific
experience?
Is
these
all
the
answers?
A
We
did
have
a
large
elective
course
in
the
spring
that
was
approximately
200
students.
We
have
focused
education.
This
is
there's
a
whole
series
of
courses,
beginning
from
an
introductory
topic
lab
with
the
focus
then
independent
student
projects
and
those
lead
up
to
BSC
and
MSC
thesis,
and
we
yeah.
We
have
a
few
people
who
do
blockchain
stuff
in
their
PhD,
but
that's
that's
really
a
whole
different
world.
We
conduct
industrial
courses
and
we
have
an
eID
digital
course
in
a
planning
that
will
be
a
mixed,
blended
modes
and
face
to
face
model.
A
That's
next
year
story.
So
what
are
these
audiences
they're?
Well
all
sorts
of
people
actually,
so
it
still
seems
to
be
high
driven
I
did
say
up
front
in
the
description
of
the
course
that
this
will
not
be
about
cryptocurrencies.
But,
as
you
know,
people
don't
read
the
e
way.
So
many
people,
many
students
came
they're
asking
about
cryptocurrencies.
We
did
speak
a
bit
about
them,
but
that
wasn't
the
focus
and,
as
a
surprise,
many
alumni
popped
up
in
the
room.
A
It's
free,
any
Hungarian
citizen
can
come
as
long
as
there
are
seats
in
the
room,
but
that
was
a
really
pleasant.
Surprise
for
me
and
real
novelty
novelty
personally
and
blockchain
focus.
We
have
students
actually
wanting
to
work
with
hyper
ledger
and
yeah
there.
We
try
to
provide
courses
at
the
decision,
maker
and
architect
level
and
also
customized
ones.
What
we
really
didn't
want
to
do
and
lose
quite
a
bit
of
money
with
I
think,
but
it
was
money.
Well
not
earned,
is
cryptocurrency
courses
because
there's
a
whole
market
for
that.
A
At
the
end,
we
ended
up
certainly
explaining
the
difference
between
the
two
worlds
and
what
the
basics
of
cryptocurrencies
are,
but
that
seems
to
be
powerful,
of
course,
still
so
on
the
course
200
students
that
was
for
an
elective
course.
That's
a
hefty
number.
Those
tend
to
max
out
at
20
at
our
university
fourteen
lectures.
Midterm
exam
homework,
the
basics.
So
what
may
be
interesting
to
you
is
the
educational
goals
and
non
goals
for
an
elective
at
an
engineering
school.
A
You
would
encounter
in
a
truly
independent
study
without
the
proper
basis,
key
concepts,
application
types
rationale
and
just
the
basics
of
crypto
financial
mekinese,
and
certainly
some
hands-on
at
the
application
level.
But
this
is
a
university
course,
so
what
even
I
was
taught
in
the
way.
Maybe
not.
This
is
not
the
good
approach,
but
even
I
was
taught
in
the
way
that
these
are
the
basics.
There's
a
documentation.
There's
your
assignment
go
and
do
that
explicit.
A
Mongos
were
Krypton
token
economics,
theoretically
and
technically
challenging
topics
yeah
well
at
the
end,
I
did
delve
into
a
few
of
those,
maybe
shouldn't
have
and
what
we
did
keep
ourselves
to
is
no
cryptography,
so
cryptographic
primitives
should
remain
cryptographic,
cryptographic
primitives
in
such
a
course
treated
as
black
boxes
key
topics.
This
is
basically
the
structure
of
the
course
first
and
foremost,
the
DLT
concept,
a
whole
lecture,
90
minutes
just
about
distributed,
ledger
technology
concept
and
its
potential
applications
and
these
properties.
How
does
it
differ
from
a
centralized
trusted?
Third
party
sphere?
A
Then
we
had
three
lectures
on
public
networks.
You
have
to
talk
about
Bitcoin,
you
have
to
talk
about
aetherium
and
you
have
to
have
a
solidity
hands
on
lecture,
because
solidity
is
slowly
creeping
in
even
into
hyper
ledger.
I
may
not
be
overjoyed
by
that,
because
I
have
my
own
strong
opinion
about
the
language,
but
this
is
how
the
field
works.
A
Second
block
permission:
consortium
that
works,
a
full
lecture
on
the
architecture
and
conceptual
elements
of
hyper
ledger
fabric,
another
one
on
composure
where
concepts
as
Oracle's
and
such
are
also
pushed
into
the
material
and
the
full
hands-on
lecture
on
composure,
because
well,
that's
d2.
Still,
although
there
are
plans
about
redoing
it
that
you
can
use
to
put
together
an
actual
business
application
at
a
high
level
that
will
work
on
a
blockchain
conceptually,
it's
super
I
understand
why
they
want
to
rework
it.
I
just
hope
that
the
good
properties
will
be
kept.
A
Third
block
is
a
overview
of
potential
and
existing
applications
in
a
specific
domain.
Now
we
are
a
department
that
has
strong
black
background
strong
and
long
running
background
in
embedded
systems
and
safety,
critical
systems
and
automotive
systems,
and
such
so
IOT
and
cyber
physical
systems
were
a
rather
natural
choice.
We
did
look
at
all
the
meaningful
use
cases
and
the
rationale
for
those
there.
You
may
have
heard
about
IBM
and
the
containers
and
the
sensors
in
the
containers
and
all
the
temperature
readings
from
the
containers
coming
into
a
fabric.
A
So,
basically,
if
you're
not
familiar
with
IOT
and
cyber-physical
systems,
that
sort
of
stuff,
when
you
have
sensors
in
the
field-
and
you
have
to
do
something
with
that
data-
and
this
was
the
point
where
I
sneaked
in
my
model
of
layered
model
of
tokenization,
the
permission
use
cases
that
I
will
show.
Briefly.
A
Fifth
block
is
system
engineering.
We
had
a
serious
look
about
writing.
Architecting,
actually
high-performance
chain
codes,
smart
contracts
in
fabric,
because
many
application
domains
require
that
period.
We
did
have
a
look
at
the
evolving
interlayer
protocol
that
has
an
implementation
in
hyper
ledger
too,
and
as
an
outlook
towards
more
theoretical
topics.
I
did
present
a
simplified
error,
propagation
model
for
fabric,
and
we
had
two
really
nice
good
guests,
so
why
this
is
important.
I
think
I
will
skip
that.
A
Anybody
who
knows
what
fall
trees
are
and
begins
to
think
about
fall,
trees
in
the
context
of
fabric
and
doors
and
policies.
We
all
know
what
I
talk
about
yeah
and
local
industry
yeah.
Actually
it's
a
little,
not
secret,
not
even
a
secret.
It's
a
fact
of
life
that
the
local
industry
is
mostly
tied
to
public
network.
So
Bitcoin
III
Amanda
like
so
those
guys,
spoke
about
such
topics
and
they
are
really
good,
so
I'm
happy
that
we
had
them.
A
So
we
chose
to
use
composer
instead
of
fabric
things
changed
in
the
last
one
year.
If
you
think
about
assigning
fabric
homeworks,
then
this
may
not
be
such
a
risky
proposition,
as
it
was
one
year
ago.
At
that
time,
I
didn't
want
to
go
there.
There
were
half
of
the
assignment
and
were
solidity.
Half
of
the
assignments
were
composure
and
people
could
apply
for
the
specific
homework
assignment.
A
Can
you
guess
what
was
the
ratio
of
the
applications
in
solidity
and
composure?
Anybody
I'm
not
really.
Even
worse,
it
was
about
70%
solidity
and
approximately
30%
for
composure.
So
the
thing
is
students.
These
are
mostly
BSC
students.
What
do
they
hear
about?
Bitcoin
III
and
the
like?
This?
Is
the
super
hip
stuff,
there's
this
slight
10%
of
students
that
that
would
have
gone
to
the
enterprise
software
direction
ten
years
ago
to
that
have
a
bright
spark
in
the
arrive
I
from
hyper
larger
fabric.
But
this
is
a
minority.
A
The
majority
came
for
the
crypto
finances,
I
hope
that
at
least
for
some
of
those
we
could
show
that
the
engineering-wise
serious
stuff
is
on
the
other
side
and
also
cookies.
What
we
seem
to
have
done
right
as
measured
by
the
midterm.
The
blockchain
is
the
ult
concept,
definitely
basics
of
Bitcoin
and
aetherium,
including
the
conceptual
basics
of
mining.
Much
of
the
possible
use
cases,
so
most
of
our
students
in
a
midterm
could
formulate
a
solution
for
a
blockchain
use
case.
A
Better
put
present
it
with
an
industrial
or
business
use
case
could
argue
about
putting
that
use
case
on
a
blockchain
and
overall
there
was
a
good
reception.
What
we
could
have
done
better
is
teaching
what
the
meaningful
use
cases
are.
So
you
know
meaning
that
something
can
go
on.
The
blockchain
doesn't
mean
that
it
should
go
on
the
blockchain,
but
even
industry
is
still
a
bit
spotty.
With
this
fabric,
architectural
consensus,
there
was
a
bit
of
an
uneven.
Take
up.
A
I
do
love
D
architectural
paper,
but
that
was
written
for
a
different
audience,
and
this
has
changed
so
there's
a
huge
shout
out
to
I
think
he's
not
here
to
see
an
Asian
and
the
documentation
working
group.
This
has
changed.
You
can
give
out
the
fabric
Docs
now
for
students,
but
I
suspect.
We
are
not
the
only
reasons
of
this,
so
the
interests
of
students
do
come
in
here
to
what
we
will
change
for
the
course
starting
I.
A
Hope
in
the
beginning
of
February
is
that
one
year
has
passed,
and
now
we
have
very
solid
use
cases
and
we
won't
be
able
to
avoid
presenting
financial
ones,
but
we
will
try
to
do
it
in
a
measured
manner
and,
to
the
extent
an
engineering
school
can
do
that
we
will
have
to
bring
in
clouds
what
we
see
in
the
industry
is
speaking
to
industrial
people.
Most
of
them
don't
really
want
to,
at
least
in
our
industrial
catchment
area,
to
do
fabric
directly
on
their
own
data
in
their
own
data.
A
Centers,
there's
all
sorts
of
clouds
where
they
even
have
DevOps
capabilities
out
of
the
box.
So
this
we
will
have
to
bring
in
at
least
in
a
demonstrational
manner
and
there's
the
next
frontier
development
processes.
How
do
you
come
from
a
problem
to
a
solution,
but
again
this
is
still
evolving
right
now,
so
I
still
don't
know
what
I
will
present
about
that.
What
is
an
interesting
proposition
is
that
standards
become
now
mature
enough
to
serve
a
scaffolding
for
such
a
course
at
least
for
the
basic
concepts
and
yeah.
A
A
If
not
next
semester
in
the
midterm.
Definitely-
and
we
do
have
a
cunning
plan,
we
will
offer
community
work
as
homework
in
the
performance
and
scale
working
group.
There
are
some
outstanding
things
that
should
be
done
by
somebody
so
that
we
can
measure
stuff
and
compare
stuff,
hopefully
in
a
in
a
enterprise
independent
way.
So
we
are
talking
with
mark
and
Dan,
and
the
other
mark
who
has
a
nice
benchmark
on
Quora
called
emerald.
That's
a
financial
systems
mensch
mark
to
simply
offering
these
necessary
truly
necessary
community
works
as
homework
options.
A
A
Much
more
serious
traction
than
certain
big-name
companies,
not
all
of
them,
but
certainly
so
on
the
side
of
industrial
courses.
If
you
do
such
things,
let
me
present
to
you
a
few,
not
so
secret
elements
of
the
secret
toolbox.
What
seems
to
be
really
important?
One
is
that
dichotomy
between
public
and
permission,
block
chains
and
consortium,
private
permissions
block
chains.
What
is
a
dichotomy
up
to
the
level
where
you
begin
to
apply
the
stuff
actually
using
smart
contracts?
So
what
is
important
is
using
smart
contracts.
A
You
can
write
middle
verse
if
you
want,
you
can
use
a
blockchain
to
use
it
as
a
quasi
notarized
messaging
system,
because
you
put
in
the
message
you
get
out
the
message
just
like
mq
only
thing
is
that
there's
an
order
in
OD
trail
there
you
can
use
it
as
storage
sure
you
can
use
it
even
use
it
for
my
secure,
multi-party
computation.
Also,
that's
still
really
tricky
on
the
mathematical
side,
so
you
can
remain
there.
Using
block
chain
is
not
about
tokens
tokenization.
A
There
are
levels
of
abstraction,
this
functionality
in
itself,
for
instance,
if
you
want
to
do
some
flight
recorder
like
a
functionality
or
continue
so
editing
or
what
like
can
be
very
worthwhile
on
its
own.
Without
all
the
stock
and
stuff
and
and
public
chains,
you
can
do
cooperation
patterns
supply
chains.
There
are
many
cooperation
patterns
there
yeah
actually
on
the
general
level.
That's
workflow
automation,
but
that's
not
the
only
thing
that
we
know
in
computer
science.
A
There
are
state
machines
to
you
and
you
can
put
state
machines
into
the
ledger
too,
because
why
not
so
there's
this
level
sure
above
that
there's
all
the
tokenization
and
asset
ization
work
that
you
can
do,
but
even
that
has
to
be
detached
from
all
the
interesting
and
sometimes
shady
market
mechanisms
and
market
economies
that
you
can
put
above
a
tokenized
or
a
citize
ledger,
and
when
you
came
up
there.
This
is
the
point
where
you
may
want
to
begin
to
think
about
crypto
economics
and
crypto
finance,
but
you
don't
have
to
do
that.
A
On
the
one
hand,
on
the
other
hand,
you
can
do
this
whole
stuff
gradually
building
up
from
the
simple
middle
there,
for
instance,
notarized
messaging
layer
up
to
providing
reverse
securitization
on
a
blockchain
there's
a
whole
book
now
about
that.
Okay-
and
this
seems
to
be
important
to
what
makes
seem
to
make
business
people
less
agitated
about
the
whole
blockchain
stuff
is
that
they
do
have
options.
You
can
go
the
private
faith
all
in
an
insurance
context,
and
this
is
woefully
outdated
and
sorry,
but
intentionally
you
can
do
from
claim.
A
Settlement
to
in
insurance
consortiums
exist
to
multi-party
insurance,
all
sorts
of
nice
things
on
permission,
block
chains.
If
you
want
to
the
public
route,
you
can
do
that
up
to
and
including
community
insurance.
There
are
a
few
Russian
companies
doing
that,
I
think
on
etherium,
and
you
can
even
build
change,
not
change
story
connections
between
the
two
words.
The
main
thing
is
that
you
have
to
apply
rational
thinking
and
you
have
to
think
about
your
requirements
and
choose
between
the
solutions
based
on
your
requirements.
So
this
was
the
education
stuff.
A
Basically,
what
I
have
gathered
this
experience?
I
hope
this
was
worthwhile
at
the
end
as
a
closing
block,
I
would
like
to
show
you
the
fun
stuff,
so
the
education,
the
course
is
200
people
and
topic
lab
with
tens
of
people's
and
such
those.
Those
are
fields
where
you
have
to
apply
tactics.
When
you
have
MSC
students,
even
PhD
students,
then
you
can
begin
to
work
on
the
fun
stuff
and
there's
really
an
enormous
amount
of
nice
possibilities
and
open
questions
in
this
fear.
A
One
thing
that
we
are
doing
in
the
topic
left
still
is
that
we
try
to
put
a
fabric
composer
overlay
on
over
smart
intersections.
There
is
a
really
good
quasi
standard
from
US
Department
of
Transportation
about
smart
intersections.
The
whole
thing
is
basically
about
vehicles,
communicating
using
radio
and
vehicles,
communicating
with
the
infrastructure
and
the
intersection
using
radio.
Now
we
do
have
a
safety
culture
and
background
in
safety.
So
premise,
one
is
that
you
don't
put
blockchain
inside
the
system
because
once
it
has
been
done
and
certified,
you
don't
touch
it.
A
That
being
said,
you
can
do
an
overlay
overlay
option.
One
is:
there
are
so-called
red
light
running
events
when
the
car
goes
into
the
intersection
when
the
light
is
red
and
the
intersection
here
recorded
can
put
it
on
a
blockchain.
The
insurance
company
can
see
it,
the
police
can
see
it
and
through
the
insurance
company,
the
insured
driver
can
contest
that
red
light
on
a
running
event
by
pictures
or
by
the
radio
signals
that
the
intersection
sent
his
car.
Think
of
unmanned
self-driving
vehicles,
the
other
one
is
preemption
tokens
they're.
A
Basically,
you
can
buy
or
get
tokens
for
requesting
the
intersection
to
basically
give
you
green
light.
We
know
that
in
the
emergency
services
context
possibly
may
have
even
some
sense
for
citizens
to
and
I,
don't
know
whether
this
will
come
to
fruition,
but
I
still
hope
that
we
can
submit
this
to
the
mobile
grand
challenge
and
we
are
doing
caliper
based
stress
testing,
that's
led
by
my
colleague
at
Lawton
clinic.
A
So
we
not
just
put
this
together
in
a
simulated
way,
but
we've
also
stress
test
it
see,
what's
the
performance
that
we
can
get
out
from
that
interesting
project
to
is
BSC
T's
is
finished
of
a
student
of
mine.
So
basically,
what
we
do
is
that
fabric
is
complex,
I,
don't
know
how
many
of
you
have
experience
in
enterprise
software.
A
One
of
the
ways
to
solve
this
conundrum
is
to
simply
model
your
network.
What
you
want
to
have
as
a
network
in
a
visual
way
reflect
that
in
a
model
and
ultimately
deploy
that
model,
so
you
may
not
want
to
configure
or
your
CAS
and
peers
and
channels
manually.
What
you
want
to
do
is
draw
this
little
nice
little
network
diagram
and
do
an
automated
deployment.
We
do
this
with
composer
and
it
works
for
a
given
definition
of
working,
but
it
works
yeah
on
chain
configuration
management
and
configuration
analysis
will
come.
A
Another
thing
that
we
do
is
taking
state
charts
in
New
York
in
the
state
chart
and
generating
automatically
the
composer
behavior
model
for
that
or
directly
jail
a
Java
chain
code,
and
we
even
had
some
initial
results
in
the
formal
analysis
of
such
Java
behaviors.
Why
is
this
important
again,
our
cyber
physical
context?
There
are
locks
that
you
can
drive
from
the
etherium
network
right
now,
so
you
can
buy
a
lot
from
a
nice
German
company
that
you
can
make
to
open
and
close
through
III
cause.
This
is
the
same.
A
This
is
actually
a
security
door,
but
as
soon
as
you
get
requirements
as
to
people
from
the
security
team
have
to
say,
ok
for
a
request
to
access
a
secure
room,
things
get
complicated,
you
have
to
draw
state
charts
and
you
have
to
analyze
them.
This
is
just
this
all
and
we
are
also
trying
to
map
out
how
you
can
systematically
argue
about
the
blockchain
efik
ability
of
a
of
an
existing
context.
I'm
doing
this
with
a
pharmacist
student
of
mine
in
our
healthcare
engineering
program.
A
B
A
A
C
Thank
you
for
sharing,
so
I
organized
a
conference
in
Singapore
and
I'm
curating
a
lot
of
this,
whether
it's
from
the
public
side
or
the
permission
side,
and
so
I
like
to
maybe
just
hear
from
you
why
you
lean
towards
the
permission
side,
because,
given
that
public
has
in
some
ways
more
of
a
movement
going
on
there's
more
youth,
there
is
more
in
some
ways
it's
more
open
source
there,
mod
who's
out
there.
At
least
this
is
for
my
impression,
I'd
love
to
hear
from
your
point
of
view,
yeah.
Okay,.
A
A
The
reason
we
lean
towards
the
permission
networks
is
that
we
are
an
engineering
school
there's,
a
plethora
of
meaningful
use,
cases
for
permission,
Ledger's
in
classic
engineering
and
business
contexts
and
there's
no
risk,
because
we
know
that
this
will
and
does
work
and
their
software
architected
specifically
for
such
use
cases
fabric
so
tooth,
mainly
in
my
interpretation.
On
the
other
hand,
the
public
networks,
despite
all
the
media
media
hype
and
all
the
enthusiasm
of
the
younger
people,
the
jury
is
still
out
what
their
future
will
be.
A
You
can
give
this
thing
the
way
you
want,
but
this
is
the
case.
Iii
room
specifically
if
it
sticks
around,
would
be
a
huge
boon
to
society
in
general
because
having
an
immutable
Democratic
in
the
way
that
anybody
can
access
that
ledger
in
a
quasi
public
like
utility,
that
that
would
have
huge
implications.
But
most
of
the
crypto
stuff
is
not
about
this,
so.
C

Think
it's
the
following:
when
I
began
to
dig
deep
into
the
public
stuff,
then
I
was
amazed
by
it
and
for
a
bit.
I
was
carried
about
by
the
novelty
and
the
by
the
radical
novelty
of
this
stuff
that
face
I
think
passes
for
most
people
spring
2018.
It
was
still
the
back
end
of
the
hype
curve
if
you
like
I,
had
attributed
to
that
this
I
don't
want
to
push
anybody
into
in
any
direction.
