Getting Started with BTTC: Writing Your First Smart Contract
BitTorrent
Inc.
has
introduced
a
beginner-friendly
guide
for
writing
smart
contracts
on
the
BitTorrent
Chain
(BTTC),
according
to
BitTorrent
Inc..
This
guide
aims
to
help
new
developers
understand
the
fundamentals
of
blockchain
development
through
a
simple ‘Hello
World’
project.
The
Contract:
Small
in
Size,
Big
in
Potential
The
tutorial
provides
a
compact
yet
powerful
HelloWorld
contract:
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.17;
contract HelloWorld {
string public greet = "Hello World!";
function getGreeting() public view returns (string memory) {
return greet;
}
}
This
contract
introduces
key
concepts
like
state
variables
and
public
functions,
serving
as
a
foundational
building
block
for
more
complex
smart
contracts.
Decoding
the
Digital
DNA
The
Greeting:
Our
Blockchain
Billboard
string public greet = "Hello World!";
This
public
string
variable
acts
as
a
permanent
message
on
the
BTTC
network,
displaying ‘Hello
World!’
for
all
to
see.
The
Getter:
Fetching
Our
Friendly
Message
function getGreeting() public view returns (string memory) {
return greet;
}
This
function
allows
users
to
retrieve
the
greeting
message
without
altering
the
contract’s
state.
Why
Two
Ways
to
Say
Hello?
The
guide
explains
the
rationale
behind
having
both
a
public
variable
and
a
getter
function:
-
Direct
Variable
Access:
The
public
keyword
automatically
creates
a
getter
function,
allowing
direct
reading
of
the
variable
from
the
blockchain. -
Custom
Function:
The
getGreeting()
function
demonstrates
how
to
create
custom
methods,
which
can
include
additional
logic
or
return
multiple
values.
Beyond
the
Basics:
Where
to
Next?
The
tutorial
encourages
developers
to
explore
further
by
modifying
the
greeting
message,
adding
logic,
or
connecting
the
contract
to
a
frontend
application.
The
Power
of
Hello
World
While
simple,
the
HelloWorld
contract
serves
as
an
introduction
to
decentralized
applications,
covering
essential
concepts
like
state
variables
and
public
functions.
These
are
the
building
blocks
for
more
complex
smart
contracts
and
DApps.
