A
Good
day,
everyone
and
welcome
to
the
casper
association
community
call
hosted
and
run
by
the
casper
association
on
this
week's
call,
we're
going
to
discuss
energy
efficiency
at
caspar
the
blockchain
and
give
a
technical
update,
we're
joined
by
meda,
ashok,
ahmet
and
joe
of
casper
labs
and
towards
the
end
of
the
call
we'll
open
up
for
a
q
a
you
can
leave
your
questions
in
the
youtube
comments
here,
live
and
we'll
try
our
best
to
answer
them
or
you
can
leave
them
on
our
telegram.
A
So
thank
you
all
for
joining
and
just
before
we
start,
I
just
wanted
to
say
we
understand,
there's
some
frustration
in
our
telegram,
but
bear
in
mind
please
it
is
up
to
exchanges
to
make
their
own
announcements
and
we're
not
allowed
to
do
that.
So
with
that
being
said,
thank
you
for
joining.
I'm
handed
it
off
to
you
piatt.
B
Very
much
joe
I'm
pierce
giubesky
vp
of
ecosystem
development
and
program
manager
at
casper
association.
Today,
as
john
mentioned,
we
have
meda
ashrock
amit
and
joe
from
casper
labs
with
me,
we'll
be
discussing
very
interesting
topic
about
energy
efficiency
in
the
context
of
the
blockchain.
B
So,
in
terms
of
the
timeline
we
just
finished
the
development
of
1.2
release.
This
series
is
our
second
major
upgrade
to
the
network.
This
will
be
released
later
during
this
month.
So
just
checking
on
the
dates
as
you
as
you
can
see,
the
development
cycle
for
1.2
is
complete.
We
are
now
undergoing
the
extensive
tests
both
on
internal
network
and
then
this
will
be.
B
The
planners
will
be
handed
over
to
the
test
set
for
the
upgrade
when
we
will
have
further
runs
of
tests
and
the
successful
process
will
be
accomplished
by
staging
their
upgrade
for
the
release
on
the
main
net.
That
should
happen
in
two
or
three
weeks
and
in
the
meantime,
as
a
team
as
a
development
team,
we
are
starting
development
of
the
third
major
upgrade
so
one
1.3.
B
This
will
take
us
more
or
less
four
weeks
and
in
the
middle
of
that
we'll
freeze
the
branch
and
we
will
start
extensive
tests.
So
this
is
a
cycle
that
is
repeating.
Our
a
very
important
date
is
to
hit
the
end
of
the
hit
the
end
of
the
june
when
we
have
tokus
unlock
event
and,
according
to
the
current
plans,
we'll
have
two
more
major
upgrades
between
on
the
details.
B
B
As
for
the
details
on
the
highway
side,
we
have
a
lot
of
design
work,
so
here
there
is
a
task
about
designing
the
synchronizer
to
enhance
it
and
on
the
road
note
side,
we
are
working
to
optimize
the
block
proposal.
We
are
also
introducing
more
enhancements
in
terms
of
into
the
deploys,
so
we
want
to
separate
transfers
and
other
deploys
in
the
block
proposal
to
also
for
for
the
convenience
and
visibility
test
and
sre
are
working
hard
to
support
the
network
and
release.
B
So
our
top
priority
is
to
keep
mainnet
and
test
that
stable,
and
we
are
also
working
on
our
own
custom
testing
framework
where
we,
which
we
are
used,
which
are
using
for
our
internal
tests
and
ecosystem,
is
very
busy
with
exchanges
support,
so
we
have
golang
sdk,
we
have
js
sdk
and
java.
Sdk
is
also
coming
golank
and
js.
They
are
available
for
in
our
github
repositories.
B
You
see,
I
also
made
this
as
an
active
link.
So
just
can
click
through
and
see
for
yourself
the
code
for
js
sdk.
We
already
made
a
couple
of
smaller
releases
with
bug
fixes
and
we
are
preparing
one
one
big
one,
and
we
want
to
do
this
in
a
new
way.
So
we
we
will
prepare
a
separate
pr
that
will
be
available
for
public
review.
So
your
comments
are
welcome
and
then
we
will.
We
will
create
this
major
release
and
deliver
and
deliver
this
to
the
community
casper
signer.
B
Here
we
have
also
good
news
for
the
community,
so
we
are
undergoing
the
constant
audit
and
that's
our
security
review
and
we'll
be
addressing
these
issues
in
the
current
countries
cycle,
as
well
as
our
usual
planned
work,
so
ui
ux
enhancements.
We
we
want
to
make
sure
that
signer
works
as
expected
and
is
also
coherent
with
the
look
and
feel
of
casper
lifeblock
explorer.
C
Absolutely
so
again,
I'm
working
on
two
medium
term
things,
one
of
them
being
the
recalculation
of
gas
costs,
and
that
is
bullet
number
one.
So
so
some
of
the
test
codes
it
does.
This
is
apparently
slightly
stale
because
you
know
it
hasn't
been
used
for
a
while.
We
introduced
various
vase
new
features
since
then,
so
I
need
to
investigate
where
exactly
the
failure
is
and
then
try
to
fix
it.
C
The
second
point
has
to
do
with
trying
to
evaluate
as
a
switch
from
the
current
method
of
allocating
validators
to
slots,
to
let's
say
to
ones
that
is
not
directly
connected
to
their
weight
so
and
that
well
that
requires
a
bit
of
math.
So
it's
still
important.
B
Thank
you
very
much.
As
for
the
update
on
the
mainnet
networks,
the
best
would
be
to
just
go
to
casper,
live
and
check
on
the
current
status.
So
we
see
here
that
we
are
getting
more
and
more
activity
on
the
network.
New
blocks
with
transfers
are
being
added
to
the
blockchain.
We
are
very
happy
that
everything
is
going
smoothly
here.
I
I
see
that
we
have
wolf
with
us
from
dev
dao
any
news
from
the
dallas
site.
Wolf.
D
Hey
guys
yeah,
so
we
are
super
psyched.
D
We
spend
a
lot
of
time
on
a
launching
event
that
literally
took
literally
took
several
days.
We
have
launched
and
processed
the
initial
few
grants
and
we're
in
the
process
of
onboarding
more
grants,
and
these
are
very,
very
exciting
times
to
say
the
least,
and
thank
you
mata
for
your
help
in
prioritizing
and
getting
this
right,
our
pipeline
is
filled
already
we're
ready
to
process.
We
need
everybody
to
literally
as
original
proposers
who
are
coming
in
with
grants
to
stand
by,
and
we've
had
several
meetings
last
night
this
morning.
D
It's
a
constant
processing.
We
need
to
get
all
this
initial
batch
of
grants
out
of
the
way
and
then
we'll
we'll
make
the
public
announcement.
B
All
right
so
two
last
things
as
as
a
team,
we
also
decided
that
we
want
to
open
ourselves
and
our
development
cycle
to
the
community,
so
we
moved
our
activity
also
in
terms
of
project
management
to
github.
B
B
You
can
check
what
is
in
our
plans
for
the
next
releases
and
for
the
future,
and
so
we
are.
Your
feedback
is
also
very
much
welcome.
So
I
invite
you
to
check
on
the
projects
and
repositories,
and
with
that
I
would
finish
my
rant
and
go
get
back
to
our
main
topic
for
today,
so
energy,
efficient
blockchain
and
yes,
I
invite
our
participants
to
to
start
the
discussion.
E
F
Hello,
everybody.
This
is
amit
patnarek.
I
am
the
quality,
control
and
release
manager
at
casper
labs
and
I'm
very
excited
to
have
joined
the
teams
a
few
months
back
and
we
at
casper
labs,
take
quality
very
seriously
and
ensure
that
quality
is
run
through
from
the
very
inception
of
any
feature
right
through
to
the
release
of
the
product.
F
We
closely
monitor
our
networks
with
various
alerts
and
other
monitoring
systems
and
ensure
that
we
rapidly
respond
to
any
defects
or
are
there
in
any
issues
that
we
encounter
for
the
purpose
of
this
call
we're
going
to
discuss
the
energy
efficiency
of
the
casper
network
compared
to
other
proof-of-work
or
other
popular
blockchains
like
bitcoin
and
ethereum,
but
I'll
get
to
that
in
a.
C
G
Okay,
I
switched
headphones.
Is
this
coming
through?
Okay?
Now?
Yes,
okay,
all
the
other
one
works
for
my
our
normal
meetings.
I'm
joe
sacker
running
the
sra
team,
keeping
everything
going
here
at
casper
labs.
G
I
am
a
mix
of
electrical
engineer
and
a
software
engineer,
so
I've
designed
tablets
done
switching
power
stuff
along
with
a
whole
bunch
of
software,
and
one
of
the
reasons
I
took
into
this
is
because
I've
got
a
good
understanding
of
power
usage
and
pieces,
and
I
guess
we
can
go
through
the
casper
analysis
first
and
then
emit
did
the
bitcoin
in
the
ethereum
analysis.
G
So
the
study
by
teed,
I
think
it
was
teet
engineering.
Teeds
engineering,
was
a
really
comprehensive
study
on
power
usage
in
the
cloud.
That
was
one
gap
that
we
didn't
have,
and
they
did
a
full
analysis
of
how
much
aws
uses
in
a
watt
per
virtual
cpu
sense
and
the
way
they
did
that
analysis
is
taking
similar
systems
and
cpus
that
exist
in
the
various
cloud
offerings
and
measuring
those
locally
and
translating
it
out.
So
we
didn't
want
to
underestimate
the
casper
usage
and
what
we
really
see
in
any
distributed.
G
Computer,
like
you
know,
casper
or
ethereum,
or
anything,
the
actual
smart
contracts,
processing,
isn't
that
complex
and
we
don't
see
a
heavy
loading
even
fully
loading
our
system
with
wasm
deploys.
G
F
As
you
all
know,
that
bitcoin
and
ethereum
are
essentially
proof-of-work
systems
and
the
atomic
unit
that
we
used
in
researching
and
calculating
the
power
consumptions
for
bitcoin
and
ethereum
was
the
hash
rate
and
a
lot
of
these
modern,
cpus
and
gpus
are
capable
of
producing
or
computing
a
good
number
achieving
good
number
of
hash
rates
and
computation.
F
So
what
we
did
is
that
we
found
out
that
some
of
the
popular
you
know
sources
for
establishing
the
power
metrics
for
bitcoin
and
ethereum,
where
university
of
cambridge
judges,
business
school,
which
runs
a
live
stats
and
the
other
one
was
digi
economist.
F
We
reviewed
a
few
others
as
well,
and
we
realized
that
there's
a
specific
formula
that
they
are
using
in
portraying
a
lower
and
upper
bound
for
the
the
power
consumption
for
bitcoin
and
ethereum
and
yeah.
We
give
benefit
of
doubt
to
both
in
the
sense
that
we
took
a
lower
value
for
that.
For
the
particular
day
we
were
researching
on
and
we
used
that
number
we
assumed.
F
We
realized
that
bitcoin
at
that
point
of
time
was
around
9500
nodes
and
ethereum
at
8
000
nodes
that
was
our
baseline
metric
for
bitcoin
and
ethereum
and,
as
joe
mentioned,
that
for
casper
we
took
a
single
node
for
machine,
which
is,
I
would
say,
undervalued.
We
could
have
assumed
a
higher
node
per
machine,
but
we
assumed
one
node
and
we
came
to
the
numbers
which
is
bitcoin,
consumes
around
95,
approximately
terawatt
per
hour
per
year
and
ethereum
around
33.5.
F
That
is
a
significant,
I
would
say
you
know
computational
difference
approximately
47
000
percent
improvement
compared
to
ethereum
and
about
136
000
compared
to
ethereum
for
a
100
node,
sorry
for
a
400
node
yeah.
So
it
is
very
clear
and
evident
that
casper
network
is
significantly
energy
efficient
compared
to
these
two
popular
blockchains.
F
Obviously,
there
were
some
some
assumptions
on
our
part
that
we
made,
which
is,
we
assumed,
a
single
node
per
machine
and
we
increased
our
validator
set
currently
set
at
100
to
around
400
and
though
our
minimum
requirement
is
4
core
cpu
32gb
ram.
We
scale
it
up
to
8
core
cpu
in
our
calculations
and,
like
I
said
earlier,
that
we
assumed
the
atomic
unit
to
be
hash
rate
and
we
discounted
any
increase
in
a
transaction
volume
which
would
adversely
impact
the
hardware
power
consumption.
F
E
F
Yes,
and
also
we
based
it
on
a
significant
amount
of
research
done
and
published
papers
from
reliable
sources
like
springer.com
and
university
of
cambridge
judge
business
school.
So
that
gives
a
lot
of
credibility
to
what
we
are
looking
into.
Yeah.
G
I
think
we
should
probably
link
the
the
paper
we
put
together
that
has
some
of
the
the
research
links
that
people
can
go
and
crawl
down
on.
I
know
we
have
that
posted
in
a
few
different
locations,
but
if
we
can.
F
H
B
I
think
we
could
move
to
the
q
a
section.
I
think
we
have
a
lot
of
traffic
over
there.
E
E
Into
effect
this
morning,
so
we
should
expect
that
to
hit
main
net.
We
should
also
talk
about
the
fact
that
there
now
that
the
token
has
some
liquidity,
there's
some
token
out
there,
validators
prospective
validators,
can
try
to
grab
a
slot
in
the
auction
correct.
I
believe
we
have
47
open
slots,
so
you
know
if
there's
validators
out
there,
that
want
to
spin
up
a
node
and
stake
the
network,
they
can
certainly
choose
to
do.
E
So
you
want
to
talk
a
little
bit
about
the
next
patch,
so
we've
got
this
patch
to
talk
about
timing
and
then,
when
the
next
patch
is
coming
out
for
1.2.
B
Yes,
so
currently
we
are
about
to
release
the
1.2
patch
to
the
test
net.
That
should
happen
end
of
this
week
or
beginning
of
the
next
week.
Then
it
will
be
followed
by
at
least
one
full
week
of
tests
and
that
when
this
will
all
get
successful,
we
will
stage
the
1.2
upgrade
for
the
mainnet
for
the
casper
network,
so
that
the
1.2,
so
the
this
major
major
upgrade
this.
This
will
happen
in
may.
B
Joe
correct
me,
if
I'm
wrong,
but
I
think
so
far
our
plans
they
weren't
changed.
G
No,
we,
since
we
came
live
this
morning.
My
hopes
were
to
get
main
net
staged
tomorrow
or
thursday
and
testnet
also
staged
thursday
or
friday.
We
found
out
that
testnet
was
fairly
active
in
getting
updates.
By
monday
we
had
94
of
the
weight
upgraded,
so
I
don't
think
we
need
to
go
for
as
many
days
as
we
did.
We
may
pull
a
day
off
of
that
timing
and
everything
would
go
fine,
but
yeah.
G
H
Yeah
well,
actually,
I
was
hoping
to
add
a
little
something
for
those
of
you
who
don't
know
me,
marco
anaballi,
I'm
the
finance
director
for
the
emerging
technology
association,
which
is
the
legal
entity
supporting
the
devdao
and
I'm
also
a
casper
advisor
and
a
mainnet
validator,
and
a
delta
in
a
validated
wobble
wipe.
I
love
this
product
anyway.
The
wolf
was
mentioning
about
the
where
things
are
standing
and
I
just
want
to
clarify
something.
H
H
There
is
a
lot
of
room
in
our
pipeline
for
development
projects
that
are
going
to
support
the
casper
network
and
support
decentralization
in
general,
and
we
welcome
anybody
to
come
to
devexdao.com
and
get
involved
in
the
process
and
propose
projects
and
get
involved
in
the
dow.
D
E
E
A
Since
all
questions
are
exchange
related
and
we
can't
really
cover
those,
I
say
we
adjourn
early
and
let
everybody
go
about
a
day,
so
I
can
wrap
this
up.
Thank
you.
Everyone
for
watching,
appreciate
you
all
being
here.
Please
subscribe,
so
you
can
see
when
we
upload
a
