Bohr Hard Fork Elevates BNB Smart Chain with Enhanced Efficiency and Scalability

BNB
Chain
has
successfully
activated
the
Bohr
hard
fork
on
the
BSC
testnet,
marking
a
significant
milestone
in
enhancing
the
blockchain’s
efficiency
and
scalability.
The
mainnet
upgrade
is
scheduled
for
September
26,
although
the
date
is
subject
to
change,
according
to
the

BNB
Chain
Blog.

Bohr
Hard
Fork
Details

The
Bohr
hard
fork
incorporates
four
Binance
Chain
Evolution
Proposals
(BEPs):

• 
  BEP
  341:
  Enables
  validators
  to
  produce
  consecutive
  blocks.
• 
  BEP
  402:
  Completes
  missing
  fields
  in
  the
  block
  header
  to
  generate
  signatures.
• 
  BEP
  404:
  Clears
  miner
  history
  when
  switching
  validator
  sets.
• 
  BEP
  410:
  Adds
  an
  agent
  for
  validators.

BEP
341,
which
allows
validators
to
produce
consecutive
blocks,
is
considered
the
most
critical
upgrade.
This
change
is
expected
to
significantly
improve
block
production
capacity
and
meet
the
growing
demands
of
the
ecosystem.

A
Closer
Look
At
BEP
341

BEP
341
introduces
a
method
for
validators
to
produce
consecutive
blocks,
transitioning
from
the
current
single-slot
system.
This
upgrade
aims
to
enhance
block
production
efficiency
and
address
the
ecosystem’s
increasing
demands.

BEP
341
has
two
essential
elements:

• 
  Number
  of
  consecutive
  blocks
  (n):
  Defines
  the
  number
  of
  successive
  blocks
  a
  validator
  can
  produce
  within
  a
  single
  epoch.
• 
  AntiMEV
  Ratio:
  Adjusts
  the
  transaction
  fee
  split
  to
  the
  SystemRewardContract
  to
  counteract
  potential
  MEV
  abuse.
  The
  transaction
  fee
  split
  increases
  linearly
  with
  the
  validator’s
  consecutive
  block
  priority
  and
  is
  capped
  by
  the
  systemRewardAntiMEVRatio,
  initially
  set
  to
  zero.
  Any
  changes
  require
  governance
  approval.

Governance
Process
for
Adjusting
Consecutive
Block
Production
in
BEP
341

While
BEP
341
is
part
of
the
Bohr
hard
fork,
its
initial
implementation
does
not
immediately
alter
the
current
setting
of
consecutive
block
production.
An
on-chain
governance
process
will
take
place
after
the
Bohr
hard
fork,
estimated
for
October
2024.
BNB
holders
and
stakers
will
vote
to
decide
on
the
change,
making
this
setting
governable
by
the
community.

Benefits
Of
BEP
341

The
implementation
of
BEP
341
with
the
Bohr
hard
fork
offers
several
benefits,
including
increased
efficiency,
greater
decentralization,
and
fair
revenue
distribution.

• 
  Improved
  Efficiency:
  Enabling
  consecutive
  block
  production
  can
  enhance
  BSC’s
  block
  production
  efficiency,
  throughput,
  and
  ability
  to
  meet
  the
  ecosystem’s
  growing
  demands.
• 
  Fair
  Revenue
  Distribution:
  BEP
  341
  ensures
  that
  validator
  and
  delegator
  revenue
  is
  evenly
  distributed
  as
  block
  production
  efficiency
  improves.
  The
  AntiMEV
  mechanism
  prevents
  high-performance
  validators
  from
  gaining
  an
  undue
  advantage,
  promoting
  fairness
  on
  the
  network.

In
Closing

The
Bohr
hard
fork
is
a
crucial
upgrade
for
BNB
Chain,
improving
efficiency
by
allowing
validators
to
produce
consecutive
blocks.
This
change
meets
growing
ecosystem
demands
while
maintaining
fairness
through
measures
like
the
AntiMEV
Ratio.
As
it
approaches
deployment
on
the
mainnet,
Bohr
is
set
to
enhance
the
chain’s
scalability
and
security,
ensuring
it
remains
robust
and
decentralized.
