Ethereum is an implementation of blockchain technology that can run smart contracts. The Ethereum virtual machine is Turing complete and can run arbitrary computation directly on the blockchain network. Whereas Bitcoin has a limited set of commands, an Ethereum contract allows an application developer to specify exactly what transactions can be performed on a contract.
What are Smart Contracts?
Smart
contracts can enable blockchain users to exchange money and property or perform
other actions among a group of users such as voting without any central
authority. For the Ethereum platform, the smart contracts are defined using a
language called Solidity.
Ever since
its release, Ethereum Blockchain has become the talk of the town due to its two
USPs, Smart Contracts and Decentralized Applications (DApps). The blockchain
network allows businesses and developers to create any number of smart
contracts and DApps they want. DApps are decentralized applications that run on
smart contracts.
To create
these DApps or smart contracts, developers must first write scripts in Solidity
Programming Language (used for smart contracts’ coding) and then call various
functions to deploy them. An alternative way to run smart contracts is to write
bash scripts that would compile and deploy them. Ethereum Truffle suite was
introduced to make this process seamless. Apart from the Truffle framework, the
suite has several components and features that make it a natural fit for your
DApps development needs.
Ethereum
Dapps, with their ability to decentralize information and services, gives Web
3.0 a platform to deliver a completely free (as in freedom) and accessible
Internet for everyone. No longer will there be a central point of control
because there won't be middle men to facilitate the flow of information and
services.
Prerequisites for developing DApps on
Ethereum Truffle Framework
Before
beginning with developing Ethereum DApps, there are a few requisites that we
need to take care of. Firstly, we will need to set up the NPM (Node Package
Manager) on our computer.
NPM will
help us install the Truffle framework. Secondly, we will need to download and
install the Ganache simulator from its official site, which will give us the
GUI development environment. Lastly, we will need to add a MetaMask extension
for our browser. MetaMask is a plugin that allows us to access Ethereum DApps
through a browser without becoming an actual blockchain node.
That’s how
you can develop and test Ethereum DApps using the Truffle framework. DApps are
just one of the many utilities of the Ethereum Network. Ethereum has a lot more
to offer, thanks to the decentralized blockchain technology.
