Solo stakers have a lot on their plate. Keeping up with every single change, how it will affect them and what steps they need to take to ensure their operation runs smoothly is a full time job! In this talk we are going to detail very clearly everything that they should be doing, everything that's coming, what tools and projects are coming to the rescue and what they are expected to do.

This
is
what
vitalik
published
not
that
long
ago-
and
this
is
the
road
map
of
ethereum
and
solo.
Stakers
are
people
that
are
not
professional
stickers,
they're,
not
professional
validators
they're
people
that
have
their
own
jobs.
There
are
people
that
might
or
might
not
have
children
they
might
have
hobbies.
They
might
have
other
things
to
do
than
just
keeping
up
with
this,
so
how
the
heck
are
they
supposed
to
keep
up
with
all
of
this,
and
that's
the
purpose
of
this
talk.
A
We're
gonna,
try
to
lay
down
in
the
next
25
minutes
the
next
things
that
are
going
to
be
huge
and
that
are
going
to
impact
us
all
as
solo
stickers
and
that
we
need
to
take
into
account
and
how
to
react
with
it.
So,
first
of
all,
let's
to
try
to
convince
these
people
that
are
still
sticking
with
Kraken
okay,
so
it
is
vital
that
there
are
more
solo
stickers.
The
reason
of
this
talk
is
because
we
need
to
convince
you
that
you
can
stake,
and
that
is
actually
worth
it.
A
It
is
valuable.
It
is
vital
for
ethereum
and
it's
actually
an
existential
threat
to
ethereum
if
we
don't
have
enough
solo
stickers.
So
we
all
have
seen
this
we'll
have
seen
how
a
very
few
entities
control
a
huge
majority
of
the
of
the
validators
who
he
remembers.
The
steam
Fiasco,
the
blockchain
steam
Fiasco
right
so
actually
having
centralized,
validators
or
centralized
centralized
with
it
actually
can
can
do
things
like
we're.
A
Just
in
Steam
Fiasco
was
just
in
sunbot
steamit,
which
was
a
company
that
was
behind
the
blockchain
Steam,
and
there
were
some
people
that
were
that
did
not
agree
with
him,
so
he
basically
went
to
poloniex
and
a
few
other
exchanges
and
said,
like
hey,
Greg,
hey
guys,
take
this
couple
Millie
and
we're
gonna
vote
for
an
invalid
State
transaction
when
the
accounts
of
these
opponents
of
mine
are
going
to
be
emptied
from
one
block
to
another.
Imagine
your
ethereum
accounts
emptied
like
this
invalid
State
transaction.
This
is
what
happens
when
we
got
centralized
validators.
A
So,
yes,
it
is
dangerous.
Okay,
but
not
only
this
there's
even
a
more
Insidious
thing,
that's
happening
in
ethereum
right
now,
right
now
we
have
compliant
block
production
through
things
like
Mev
boost.
We
have
a
32
percent
of
the
blocks
being
produced
in
ethereum
right
now,
at
32
percent
of
blocks
produced
that
are
ofac
compliant.
That
means
that
if
you
have
ever
used
tornado
cash
there's
a
32
percent
of
the
blocks
where
your
transactions
are
not
going
in,
did
you
know
that?
Did
you
know
that
you're
being
censored
in
32
of
the
blocks?
A
This
is
huge
and
this
is
Mev
boost
and
if
we
go
into
the
Meb
boost
produce
blocks,
this
is
87
are
come
from
relayers
that
have
said
that
they
are
going
to
comply
with
ofac.
This
is
why
it's
so
important
right,
Okay.
So
brief,
brief
introduction
to
dab
node
dabnode,
we're
here
to
make
it
easy
we're
here
to
make
it
easier
for
people
to
run
nodes.
A
A
Then
there's
like
all
sorts
of
nice
beautiful
things
like
a
web
3
standard
that
holds
the
keys
for
you,
etc,
etc,
and
there's
a
huge
community
of
thousands
of
validators
that
are
doing
exactly
the
exact
same
thing
as
you
and
where
you
can
just
lay
it
rely
on
them,
ask
for
support
Etc.
This
is
one
of
the
things
that
we
have
done.
A
A
The
thing
that
the
solo
Staker
needs
to
know
is
that
you
are
the
key
for
the
future
of
ethereum
right,
mov,
ing,
okay,
so
Mev
MV
stands
for
maximal
extractable
value,
and
the
first
thing
that
we
need
to
know
here
is
that
the
value
is
extracted
from
who,
from
the
user
and
people
say
like
oh
Mev,
but
they're
doing
nice
things
they
do
Arbitrage
between
dexes.
So
we
can
like
if
I
have
a
token,
my
price
will
be
the
same
everywhere.
Yeah,
that's
a
good
thing
right,
but
how
about
everything
else?
A
You've
got
price
execution
in
every
trade
that
you
do
in
a
decks.
You
got
gas
Wars
and
network
congestion.
Whenever
there's
like
a
juicy
Mev
opportunity,
you
get
the
potential
and
the
threat
of
chain
reorgs.
If
there's
something
really
juicy
and
the
conditions
are
right
and
the
validators
are
incentivized
to
attack
themselves.
So
if
I
come
after
the
a
block
where
there's
a
really
juicy
Mev
opportunity,
I
mean
send
device
to
screw
up
the
guy
that
comes
before
me.
So
I
can
keep
the
Mev
opportunity
right.
A
B
So
yes,
how
to
map
all
of
these
related
to
me
beef,
so
mainly
for
me
and
for
most
of
us.
Maybe
it's
not
a
feature.
It's
a
bug.
It
has
a
lot
of
implications
on
the
ethereum
design
because
of
that,
because
it's
something
that
is
leading
in
a
in
the
wrong
direction,
so
mainly
PBS,
has
formed
to
try
to
mitigate
this
situation.
Pbs
proposal
block
separation
and
we
are
going
to
talk
about
that
later
on.
B
Anonymity
is
something
that
is
also
resetting
right
now,
and
we
are
talking
later
on.
So
mainly,
we
are
seeing
how
the
Syrian
Foundation
is
trying
to
find
ways
to
mitigate
this
situation
at
a
protocol
level,
but
there
are
something
that
we
cannot
mitigate
so
far.
We
have
seen
that
is
really
really
hard
to
find
a
solution
to
Meb.
So
that
is
why
the
PBS-
or
maybe
smoothing,
is
a
way
to
make
this
more
fair
and
try
to
mitigate
the
situations.
A
Is
a
centralizing
force?
It's
a
centralizing
force
because
I
mean
researchers
will
not
give
you
as
a
solo
Staker
a
juicy
10
million
Mev
opportunity,
because
you,
as
a
solo
sticker
that
has
only
42
000
32
each
in
this
in
your
validator.
You
would
be.
You
would
be
happy
to
take
this
10
million
shut
down
your
validator
and
go
live
in
the
Bahamas
for
the
rest
of
your
life,
so
it
is
a
trustful
system
and
as
a
solo
sticker,
you
cannot
access
Mev
opportunities.
A
B
A
Centralizing
Force
that
but
yeah,
that's
that
basically
makes
that
us,
as
solo
stickers,
will
only
have
two
sources
of
revenue
which
are
block
production,
so
block
reward
and
transaction
fees
and
the
big
companies.
The
big
trusted
companies
that
can
sign
agreements
would
have
those
two
plus
MAV
opportunities.
So
Mev
boost
is
for
now,
as
solo
stickers.
The
only
solution
that
we
have
to
access
this.
B
A
Okay,
DVT
DVT
is
the
next
Hot
Topic
and
it's
distributed
validators.
So
right
now,
there's
there's
this
equality
of
one
validator
key
one
validator
client,
which
basically
means
that
whoever
runs
the
machine.
Whoever
runs
the
validator
client
also
has
access
to
that
key
and
can
do
all
sorts
of
bad
things
to
this
it
can.
It
can
slash
you,
it
can
Ransom
you,
it
can
just
exit
you,
it
can
just
shut
the
validator
down,
so
you
get
inactivity,
leak
and
DVT
comes
in
so
the
the
DVD
comes
in.
A
B
A
If
one
of
them
are
offline,
we
can
still
continue
validating.
It
also
allows
for
different
trust
assumptions,
because
you
can
distribute
these
shares.
So
nobody
with
with
one
of
these
shares
you
can't
do
or
you
can't
slash
people
you
can't
exit.
You
can't
do
all
of
this
stuff.
So
actually
we
do
not
require
so
much.
We
can
afford
to
give
these
keys
to
other
people
and
not
require
so
much
collateral.
A
A
Moreover,
those
who
run
already
run
nodes
and
already
have
a
validator
setup.
They
can
monetize
through
DVT
Technologies
on
top
of
their
validator
sets.
So
it's
a
way
to
bump
up
your
your
your
rewards
for
having
a
validator
okay.
So
exactly
that's,
that's
exactly
what
you
need
to
know
about.
Dvt
you'll
be
able
to
monetize
your
machine
by
leveraging
other
protocols
on
top
of
it.
A
These
Protocols
are
like
SSV,
Network
or
opal
or
Diva,
and
that
people
will
be
able
to
participate
in
validation
even
with
less
than
32e,
because
you
can
do
a
setup
and
then
you
can
participate
in
this,
which
is
great
for
accessibility,
because
we're
making
part
of
the
benefits
of
running
infrastructure
to
people
that
do
not
that
are
not
rich
people
do
not
have
32
each.
So
it's
great
for
accessibility,
all
right
withdrawals,
yep
with
roles
with
roles.
That's
what
all
we're
waiting
for
right
like
we've
got.
A
This
32
withdrawals
are
going
to
be
a
new
system
level
operation
which
will
have
no
gas
cost
and
it
will.
They
will
not
even
go
to
the
evm.
They
will
increase
the
the
balance
of
the
withdrawal
address
automatically
it'll
be
a
limited
block
per
block.
Just
like
right
now,
joining
as
a
validator
is
also
limited
block
of
work.
There's
a
limited
amount
of
of
people
that
can
join
the
validator
set.
A
B
Right
so
yeah
now
it's
time
to
talk
about
product
line
charting
and
the
future
of
overthem,
so
mainly
the
the
roadmap
Institute
changed
completely
at
the
moment
that
vitalik
make
these
credit
post.
So
mainly,
we
realized
that
if
we
facility
they
have
better
scalability
and
potential
that
the
previous
execution
shouts,
so
mainly
everything
changed.
At
that
moment,
we
forget
about
having
execution
on
the
charts
and
we
move
to
a
way
to
provide
data
availability
for
other
layer,
2
applications
that
are
going
to
happen
during
these
years.
B
So
mainly
mainly
the
thing
that
happened
with
the
product
and
starting
is
that,
instead
of
providing
more
space
for
transactions,
we
are,
we
are
going
to
provide
more
space
for
data
that
the
layer
2
Solutions,
can
use
it
in
the
future.
So
the
idea
is
mainly
that
the
execution
is
going
to
happen
on
these
SQL
VMS
and
prolapse
keeping
the
execution
part
of
ethereum,
as
it
is
mainly
from
the
point
of
view.
B
A
So
what
do
we
need
to
know?
We
need
to
know
that
those
blobs
those
new
Blobs
of
data
will
be
stored
in
the
beacon
chain,
which
will
mean
that
our
Beacon
chains
as
validator
service
takers
will
grow,
will
bloat
but
hey.
It
will
not
grow
indefinitely,
because
this
data
will
only
be
stored
for
about
a
month.
So
that's
great
so
we'll
have
the
hour.
B
Next,
big
topic:
anonymity,
yeah,
that's
also
a
critical
point
of
the
network,
so
yeah.
The
thing
is,
since
we
are
using
random
in
the
we
can
change
to
select
the
validator
proposals,
it's
possible
to
know
beforehan,
who
is
going
to
be
the
next
one,
and
since
we
are
using
lip
to
be
Network
to
communicate
with
this
node,
it's
also
possible
to
get
the
IP
of
the
nodes.
B
So
mainly
the
thing
is
that,
since
we
have
also
myth
in
this
situation,
people
want
or
could
try
to
attack
this
node
because
they
can
get
the
minor
attraction
value.
The
maximum
extraction
value
from
the
block
so
at
the
end,
is
the
the
same
problem
that
before
we
are
putting
the
integration
to
attack
the
network,
so
we
are
making
yeah
right
Integrations
for
for
the
The
Source
takers,
but
this
is
not
just
that.
B
So
what
you?
What
do
you
need
to
know
about
this
yeah?
Because
the
list
of
proposal
of
the
new
ebook
are
now
it's
possible
to
be
targeted
by
these
attackers?
Disney
protocol
protects
the
privacy
of
the
evaluators
at
the
moment
to
proposal
the
block,
but
we
need
also
new
ways
to
hide
the
communication
between
nodes,
because
that
is
still
spouses.
So
that
is
why
private
Solutions,
like
Hopper
or
other,
can
provide
this
kind
of
privacy
protection
at
IP
level.
B
B
A
good
one,
so
yeah
this
is
how
this
has
been
a
Hot
Topic
in
the
research
part
of
the
protocol
from
several
years
ago.
So
mainly,
the
thing
that
we
have
now
right
now
is
that
we
need
to
have
all
the
state
of
execution
client
to
be
able
to
be
to
be
able
to
verify
the
next
block.
So
this
is
a
problem
because
we
are
taking
all
the
complexity,
all
the
historical
data
from
the
ethereum,
and
we
are
need
to
store
this
in
in
our
devices
to
be
a
solo
stickers.
A
So
either
you're
telling
me
that
we,
if
we
create
a
block
through
this
through
this
witness
and
through
this
proof,
we
can
prove
the
only
the
parts
of
the
state
that
we
need
to
prove
that
this
block
is
valid
and
included
in
the
block
itself.
So
a
validator
of
the
block
will
be
able
to
look
at
the
Block
in
itself
and
be
able
and
it'll
include
this
person.
You'll
be
able
to
tell
if
it's
valid
or
not
yeah.
B
Pbs
PBS
is
going
to
be
also
a
very
important
part
of
the
protocol
because
they
think
that
Paul
just
mentioned
so
mainly
the
idea
is
that
we
are
going
to
split
the
roles
on
the
network.
We
are
going
to
have
proposal
and
and
blood
producers,
so
my
lead
idea
is
that
the
block
producer
is
the
one
that
is
going
to
create
all
of
these
to
generate
the
equitness
and
and
is
the
one
that
is
going
to
take
this
High
computation.
B
B
B
We
are
going
to
be
the
same,
he's
going
to
increase
the
bandwidth,
but
not
too
much,
because
we
are
going
to
move
for
from
producer
medical
trees
to
Vertical
trees
that
are
more
efficient
ways
to
prove
the
state
so
mainly
as
a
validator
I
think
the
result
is
going
to
be
more
or
less
same.
It
has
been
always
a
a
need
that
evaluators
needs
to
be
running
custom
Hardware.
So
we
keep
on
that
level.
A
Okay,
I'm
gonna,
take
the
Dan
shot,
the
Dank
sharding
and
data
availability
sampling
okay.
So
this
is
going
to
be
the
last
thing
and
the
key
part
to
that
solo
stickers
need
to
know
right
now
about
this
is
that
we
do
not
know
which
are
the
consequences
that
it
will
have.
So
we
cannot
possibly
know
right
now,
because
there's
not
a
specific
implementation
of
the
data
availability
sampling,
so
database
example.
A
What
it
will
allow
us
is
to
remember
those
Blobs
of
data
that
we
have
mentioned
before,
so
these
Blobs
of
data
will
not
necessarily
be
fully
downloaded.
We
will
be
able
to
just
prove
a
sample
of
this
to
take
a
sample
