Ethereum Developers Discuss Pectra Upgrade and PeerDAS in Consensus Call #140

On
August
22,
2024,
Ethereum
developers
gathered
over
Zoom
for
All
Core
Developers
Consensus
(ACDC)
call
#140,
according
to
Galaxy.com.
The
bi-weekly
meeting
focused
on
discussing
and
coordinating
changes
to
the
consensus
layer
(CL)
of
Ethereum,
also
known
as
the
Beacon
Chain.
The
call
was
chaired
by
Ethereum
Foundation
(EF)
Researcher
Alex
Stokes.

Pectra
Upgrade

Stokes
flagged
a
new
CL
specifications
release
for
the
Pectra
upgrade,
tagged
as

v1.5.0-alpha.5,
encouraging
client
teams
to
review
it.
EF
Developer
Operations
Engineer
Parithosh
Jayanthi
noted
that
the
Geth
client
has
produced
invalid
blocks
on
Pectra
Devnet
2,
which
developers
are
investigating.
Additionally,
the
Erigon
client
is
facing
issues
staying
connected
to
the
canonical
chain,
and
there
is
a
JSON
RPC
standardization
issue
in
execution
layer
(EL)
clients
causing
additional
problems.

Pectra
Devnet
3

Stokes
confirmed
the
launch
of
Pectra
Devnet
3
in
one
week’s
time,
with
specifications
available

here.
The
update
to
EIP
2935,
which
saves
historical
block
hashes
in
state,
will
be
incorporated
into
Devnet
3.

EIP
7251
Update

Developers
are
considering
an
update
to
EIP
7251
to
address
an
edge
case
where
the
correlation
penalty
is
incorrectly
computed
for
a
slashed
validator
with
a
large
effective
balance.
Stokes
encouraged
client
teams
to
review
the
updates,
which
can
be
found

here.

Beacon
Block
Body
Update

Developers
discussed
adding
a
new
field
in
the
Beacon
block
called
“ExecutionClientRequests”
to
simplify
state
transitions
post-Pectra
upgrade.
The
proposal
can
be
reviewed
in
detail

here.

Engine
API
Update

A
proposal
by
Geth
developer
“Lightclient”
to
simplify
block
conversion
for
EL
clients
was
generally
well-received.
The
change,
which
aims
to
unify
requests
into
a
single
type,
can
be
reviewed

here.

PeerDAS

EF
Developers
Operations
Engineer
Barnabas
Busa
announced
that
PeerDAS
Devnet
2
would
launch
on
August
23.
Stokes
shared
progress
on

EIP
7742,
which
aims
to
update
the
blob
gas
target
and
maximum
dynamically.
Representatives
from
Lodestar
and
Lightclient
teams
expressed
support
for
including
EIP
7742
in
the
Pectra
upgrade.

Developers
also
discussed
blob
count
configurability
in
clients
but
made
no
concrete
decisions.
Progress
continues
on
EIP
7688,
forward
compatible
consensus
data
structures,
though
its
inclusion
in
Pectra
remains
undecided.
Further
details
can
be
found

here.

Research

Developers
agreed
to
name
the
next
CL
upgrade
“Fulu”
after
a
star
in
the
Cassiopeia
constellation.
A
representative
from
ProbeLabs
shared
insights
on
message
propagation
through
Ethereum’s
networking
layer
post-Dencun
upgrade.
Their
analysis
can
be
read

more
detail
