One
of
the
most
promising
applications
of
blockchain
is
in

supply
chain
management.
From
increasing
transparency
to
reducing
fraud
and
improving
efficiency,
blockchain
is
revolutionizing
how
goods
move
from
manufacturers
to
consumers.
In
this
step-by-step
explainer,
we’ll
explore
how
blockchain
works
in
supply
chains,
why
it
matters,
and
how
it
is
reshaping
traditional
supply
chain
processes.

1.
Understanding
Blockchain
Technology

Before
diving
into
the
impact
on
supply
chains,
it’s
essential
to
understand
what
blockchain
is.
In
simple
terms,

blockchain
is
a

distributed
ledger
or
a
decentralized
database
that
records
transactions
across
multiple
computers
in
a
secure,
transparent,
and
immutable
way.
Each
transaction
is
grouped
into
a
“block”
and
added
to
a
“chain”
of
previous
transactions,
forming
a
permanent
record.
The
key
features
of
blockchain
include:

• 
  Decentralization:
  No
  single
  entity
  controls
  the
  data;
  it’s
  maintained
  by
  a
  network
  of
  participants.
• 
  Immutability:
  Once
  recorded,
  data
  cannot
  be
  altered
  without
  the
  consensus
  of
  the
  entire
  network.
• 
  Transparency:
  All
  participants
  can
  view
  and
  verify
  transactions,
  ensuring
  full
  visibility.

Now,
let’s
see
how
this
innovative
technology
applies
to
the
complex
world
of
supply
chains.

by
introducing

automation,

transparency,
and

trust
across
the
entire
supply
chain.
Here’s
a
step-by-step
breakdown
of
how
blockchain
is
transforming
supply
chains:

a.
Enhanced
Transparency
and
Trust

Blockchain
allows
for
complete

end-to-end
visibility
in
the
supply

Every
participant,
from
manufacturers
to
retailers,
can
access
the
same
data
in
real-time.
This
ensures
that
each
transaction,
from
the
sourcing
of
raw
materials
to
the
delivery
of
the
final
product,
is
recorded
transparently
and
cannot
be
altered.
For
example,
consider
a
luxury
watch
brand
that
wants
to
ensure
its
products
are
made
using
ethically
sourced
materials.
With
