What is Solidity Compiler?

Ethereum
is
the
biggest
playground
for
developing

smart
contracts
in
the
existing

blockchain
landscape.
Developers
trust
Ethereum
as
it
was
the
first
blockchain
to
introduce
the
benefits
of
smart
contract
programmability.
The
ideal
programming
language
to
create
smart
contracts
on
Ethereum
is

Solidity.
It
offers
a
wide
range
of
features
that
help
in

Solidity
compiler
to
deploy
smart
contracts
according
to
your
desired
use
case.

Ethereum
developers
must
use
a
compiler
to
ensure
that
the

Ethereum
Virtual
Machine
or
EVM
can
interpret
and
execute
the
commands
in
the
code.
In
other
words,
the
Solidity
compiler
facilitates
conversion
of
the
code
to
a
set
of
byte
instructions.

Understanding
the
Fundamentals
of
Solidity
Compiler 

Solidity
is
a
popular
programming
language
for
creating
smart
contracts
on
Ethereum
blockchain.
It
has
gained
significant
improvements
in
popularity
as
the
demand
for

web3,

dApps,
and
smart
contracts
grows
exponentially.
Therefore,
it
is
important
to
know
about
all
the
essential
tools
to
create
smart
contracts
with
Solidity. 

The
answers
to
‘What
is
Solidity
compiler’
primarily
focus
on
its
nature
as
an
open-source
compiler
that
helps
in
translation
of
code
in
Solidity
programming
language
to
bytecode.
It
serves
as
the
bridge
for
communication
between
developers
and
the
Ethereum
Virtual
Machine.
Solidity
compiler
ensures
that
the
smart
contract
code
follows
the
important
rules
and
requirements
associated
with
Ethereum
blockchain.

You
can
come
across
two
different
types
of
Solidity
compilers,
such
as
solc
and
solc.js.
The
original
version
of
Solidity
compiler
has
been
written
in
Go
programming
language.
On
the
other
hand,
the
fundamentals
of
Solidity
compiler
explained
for
beginners
also
emphasize
how
solc.js
leverages
Emscripten
for
compiling
C++
code
to
JavaScript.
The
Node.js
library,
alongside
the
solcjs
command
line
tool,
helps
to
assemble
Solidity
files.
Furthermore,
it
also
uses
JavaScript
for
compilation
with
the
advantage
of
flexible
installation.

How
Does
the
Solidity
Compiler
Work?

The
working
of
smart
contracts
is
a
complicated
process
from
a
technical
perspective.
You
can
look
at
them
as
automated
contracts
that
execute
upon
fulfillment
of
certain
conditions.
On
the
other
hand,
smart
contracts
depend
on
code
to
make
everything
possible.
Developers
write
code
in
a
language
they
can
understand. 

However,
machines
must
understand
the
smart
contract
code
to
execute
them
successfully.
Compilation
of
smart
contract
code
to
bytecode
is
an
important
requirement
to
help
the
EVM
understand
the
code.
Bytecode
primarily
includes
binary
computer
instructions
and
is
deployed
directly
to
the
Ethereum
blockchain. 

The
process
to
compile
Solidity
code
also
leads
to
the
generation
of
an

Application
Binary
Interface
or
ABI.
It
serves
as
the
interface
between
program
modules,
such
as
user
programs
and
operating
systems.
The
bytecode
deployed
on
Ethereum
blockchain
is
saved
at
a
specific
address
that
would
be
publicly
available
and
allows
everyone
to
interact
with
the
smart
contract.

The
address
represents
the
instance
of
a
deployed
contract
and
also
offers
persistent
storage
for
the
maintenance
of
internal
state
of
the
smart
contract.
Native

cryptocurrency
of
Ethereum,

ETH,
offers
a
store
of
value
and
a
trusted
method
of
payment
to
facilitate
execution
of
smart
contracts
on
the
blockchain. 

What
are
the
Special
Highlights
of
Solidity
Compiler?

Solidity
compiler
is
an
integral
part
of
the
process
of
developing
and
implementing
smart
contracts
on
Ethereum
blockchain.
Before
you
dive
into
the
practical
aspects
of
using
Solidity
compiler,
you
must
know
about
its
special
highlights.
The
important
details
of
Solidity
compiler
you
must
learn
to
understand
it
effectively
include
Solidity
compiler
versions,
plugins,
settings,
and
APIs.

Solidity
compiler
also
offers
flexibility
in
extending
its
functionalities
with
the
help
of
plugins.
Developers
can
use
plugins
to
introduce
new
language
features
or
for
custom
optimizations.
Interestingly,
you
can
write
plugins
in
any
programming
language,
such
as
Python
and

Rust,
with
the
flexibility
for
seamless
interfacing
with
Solidity
compiler.

Another
important
detail
about
Solidity
compiler
invites
attention
to
its
settings.
The
answers
to
“What
is
Solidity
Compiler”
also
draw
attention
towards
the
flexibility
for
configuration
of
control
over
compilation
of
Solidity
code.
The
important
Solidity
compiler
settings
include
the
gas
limit,
the
target
EVM
version,
and
the
optimization
level.

You
can
specify
the
version
of
the
EVM
with
which
the
bytecode
will
be
compatible.
The
gas
limit
allows
you
to
specify
the
amount
of
gas
required
to
execute
bytecode
on
Ethereum.
On
the
other
hand,
the
optimization
level
represents
the
aggressiveness
with
which
the
Solidity
compiler
would
refine
the
bytecode.

The
distinctiveness
of
Solidity
compiler
versions
ensures
that
every
version
comes
with
unique
features
as
well
as
limitations.
For
instance,
you
might
find
compatibility
for
new
features
like
ABIEncoderV2
in
some
versions
of
Solidity
compiler.
Developers
have
to
choose
the
right
Solidity
compiler
version
according
to
the
requirements
of
their
smart
contracts.

You
can
also
find
better
prospects
for
using
Solidity
compiler
with
the
help
of
APIs.
Developers
can
use
APIs
to
programmatically
compile
Solidity
code
from
other
applications.
The
APIs
can
help
in
creating
tools
like
integrated
development
environments
and
code
analyzers
that
empower
the
Solidity
development
workflow
with
automation.
