Buterin’s
Focus
on
Proof-of-Stake
Centralization
Risks

Ethereum
co-founder
Vitalik
Buterin
has
once
again
addressed
critical
issues
related
to
the
blockchain’s
decentralization,
this
time
focusing
on
the
risks
posed
by
the
network’s
proof-of-stake
(PoS)
system.
In
his
latest
blog
post,
Buterin
explores
the
potential
threats
of
centralization
and
outlines
several
strategies
aimed
at
mitigating
these
risks,
aligning
with
Ethereum’s
ongoing
“Scourge”
upgrade.
This
upgrade
comes
as
Ethereum
continues
its
transition
toward
a
more
scalable
and
secure
blockchain,
following
the
successful
implementation
of
the
“Merge”
and
“Surge”
upgrades,
which
enabled
Ethereum
to
process
up
to
100,000
transactions
per
second.

Buterin’s
focus
in
this
post
revolves
around
two
main
areas:
block
construction
and
staking
capital.
Both
aspects,
he
argues,
present
significant
risks
to
Ethereum’s
decentralization
if
not
addressed
proactively.
As
institutional
interest
in
Ethereum
grows,
particularly
with
the
launch
of
Ether-based
ETFs,
and
with
30%
of
the
total
ether
supply
already
staked,
these
concerns
are
becoming
more
pronounced.

Block
Construction
and
MEV
Concerns

One
of
the
key
risks
Buterin
discusses
is
related
to
block
construction.
Currently,
around
88%
of
Ethereum
blocks
are
constructed
by
just
two
entities.
This
high
degree
of
centralization
poses
a
potential
threat
to
the
blockchain’s
censorship
resistance,
particularly
due
to
the
concept
of
maximal
extractable
value
(MEV).
MEV
allows
block
proposers
to
reorder
or
exclude
transactions
in
a
way
that
benefits
them
financially,
potentially
leading
to
unfair
advantages,
transaction
delays,
and
reduced
transparency.

To
address
this
issue,
Buterin
suggests
the
possibility
of
using
an
encrypted
mempool.
An
encrypted
mempool
would
make
it
much
more
difficult
for
block
proposers
to
censor
transactions
or
reorder
them
for
personal
gain.
However,
he
acknowledges
that
designing
a
practical
and
efficient
encrypted
mempool
for
real-world
use
is
still
a
work
in
progress.
This
proposed
solution
is
part
of
a
broader
effort
to
ensure
that
Ethereum’s
block
construction
remains
decentralized,
avoiding
situations
where
a
few
powerful
entities
have
disproportionate
control
over
the
network.

Staking
Capital:
Striking
a
Balance

The
second
major
risk
Buterin
points
out
is
in
staking
capital
provision.
With
approximately
30%
of
Ethereum’s
total
supply
currently
staked,
the
network
is
well-protected
from
51%
attacks.
However,
as
the
amount
of
staked
ether
grows
closer
to
100%,
several
concerns
arise.
These
include
the
weakening
of
slashing
penalties
(which
are
meant
to
deter
malicious
behavior),
the
overproduction
of
new
ether
(potentially
up
to
one
million
additional
ether
annually),
and
the
possibility
of
one
dominant
liquid
staking
token
monopolizing
the
network.
Such
a
situation
could
undermine
Ethereum’s
decentralization
and
its
broader
monetary
properties.

Buterin
emphasizes
that
it’s
crucial
to
maintain
a
careful
balance
when
it
comes
to
staking
capital.
While
stakers
play
a
vital
role
in
securing
the
network,
excessive
staking
could
lead
to
new
risks,
including
a
concentration
of
power
in
the
hands
of
a
few
large
players.
This
centralization
could
make
the
network
more
vulnerable
to
censorship
and
reduce
its
overall
security.

Buterin’s
proposed
strategies
are
essential
steps
toward
addressing
these
centralization
risks.
As
Ethereum
moves
toward
the
next
phase
of
its
evolution
with
the
“Scourge”
upgrade,
the
community
will
need
to
consider
these
solutions
carefully
to
ensure
that
Ethereum
remains
both
decentralized
and
secure,
even
as
it
scales
to
meet
increasing
demand.
The
ongoing
developments
reflect
Ethereum’s
commitment
to
staying
ahead
of
potential
threats
while
fostering
an
open,
decentralized
blockchain
ecosystem
