Node
Operators
and
Miners:
Action
Required

If
you
are
a
node
operator
or
miner,
you
need
to
follow
these
steps:

• Upgrade
  your
  node
  before
  the
  epoch
  number
  reaches
  173520000
  (estimated
  at
  May
  30,
  15:00
  (GMT+8)).
  Replace
  
conflux.exe
  with
  the
  new
  one
  in
  Conflux
  v2.4.0-testnet
  under
  the
  
run
  directory,
  then
  restart
  the
  node.
• If
  upgrading
  after
  the
  epoch
  number
  reaches
  173520000,
  delete
  all
  data
  and
  restart
  the
  node.
• If
  starting
  a
  new
  node,
  download
  the
  latest
  version
  of
  Conflux
  v2.4.0-testnet
  and
  run
  it.

Consequences
of
Not
Upgrading

Failing
to
upgrade
your
Conflux
node
will
result
in
incompatibility
with
the
upgraded
Conflux
protocol,
leading
to
disabled
functions
such
as
block
synchronization
and





mining.

Community
Support

Conflux
extends
its
gratitude
to
the
community
and
developers
for
their
continued
support
and
contributions.
This
upgrade
is
a
step
towards
a
more
robust
and
efficient
future
for
the
Conflux
network.
