How to become a Hedera Hashgraph Developer?

This post will walk you through obtaining your account credentials and setting yourself up for success in deploying your application by being a Hedera Hashgraph developer. We’ve broken down the steps for you to follow along easily. Let’s get started!

You will go through the following steps.

Step 1 – Create a free development account

Step 2 – Select your Software Development Kit

Step 3 – Follow a Hedera tutorial

Step 4 – Get started with examples

Why choose Hedera for your Decentralized Application?

If you are searching for a network for your decentralized application development, you may want to consider Hedera. Hedera is fast, fair, secure, sustainable, and cost-effective, making it a great option for businesses seeking to meet their environmental sustainability goals. With a low carbon footprint and the ability to handle 10,000 transactions per second for native services and over 400 tps for smart contracts, Hedera is an efficient choice that won’t be held back by throughput constraints. Plus, with an average transaction cost of just $0.0001, you can easily predict and plan the costs for your business. And, with a transparent governance model, you can trust that your business and applications will be built on a stable and reliable platform without the risk of forks.

What does Hedera offer for your dApp?

The Hedera network offers various services to aid in decentralized application development, such as

Smart Contract Service: Allows for building and deploying Solidity smart contracts on the network. Although using the Hedera Token Service for minting tokens is recommended, integration with smart contracts is expected in the near future.

Token Service: Hedera allows for the configuration, minting, and management of both fungible and non-fungible tokens on the Hedera network without the need to deploy a smart contract.

Consensus Service: It provides verifiable timestamping and ordering of events for any application or permissioned blockchain framework.

File Service: It enables the distribution of files to each node on the network. This service is not intended for large file storage but can be useful for storing files that require active storage on the ledger, such as Solidity code or address books.

Step 1 – Create a free development account

If you’re looking to start developing on Hedera, you can get started for free using the Hedera test network (testnet). Simply go to the Hedera Developer Portal to create a testnet account. This account will be replenished with 10,000 fake hbar every 24 hours. When you’re ready to deploy your application to the mainnet, you’ll need to create a mainnet account through a supported wallet and pay for transactions using real hbar.

Your Tesnet account will have these three components

• A private key, 
• A public key 
• An account

Store the information about these three components securely once you have your Testnet Account. If your private key isn’t secure, it can grant access to bad actors while moving your application up the network. 

Step 2 – Select your Software Development Kit

Hedera SDKs (Software Development Kits) make it easier for developers by letting them use their familiar languages. SDKs are currently written in Go, .NET, JavaScript, Java, and more. Check out other options here. 

You will be able to install your chosen SDK with common toolkits. Hedera Hashgraph developer can use the tutorial on Java where you can set it up with Maven. For JavaScript you can use the tutorial to begin with npm; for .NET you can get started with Nuget. If you’re interested in using one of the other available SDKs, Hedera provides support for various programming languages and is regularly updated as they develop these projects.

The Hedera documentation is a valuable resource that provides detailed information and examples for various functions. It can be helpful when you’re trying to create a smart contract, use the Hedera Token Service (HTS) to create a token, or utilize the Hedera Consensus Service (HCS) to create a topic. Be sure to refer to the documentation regularly as you work on your projects.

Step 3 – Follow Hedera’s tutorial

A tutorial series in JavaScript is available for those who want to learn how to set up a local development environment and submit transactions to the testnet on the Hedera network. The platform also provides entry-level tutorials for developers who prefer Java or .NET. 

In addition to the tutorials, the SDK documentation is accessible for reference. The Hedera API is implemented the same way regardless of the programming language, so developers should find the documentation familiar regardless of their language.

Exploring examples is an effective way to learn new concepts, and Hedera Hashgraph developer is offered many examples and tutorials that you can reference and use as a starting point. By running through these examples, you can quickly understand how different features work and how to implement them in your projects. 

Below, you can find an example code for a smart contract written for Hedera Hashgraph. The code has an owner variable that stores the address of the contract’s owner, a constructor that sets the owner to the address of the account that deployed the contract, a transferOwnership function that allows the current owner to transfer ownership to a new

pragma solidity ^0.8.0;

contract SimpleHederaHashgraph {
  address public owner;

  constructor() public {
    owner = msg.sender;
  }

  function transferOwnership(address newOwner) public {
    require(msg.sender == owner);
    owner = newOwner;
  }

  function getOwner() public view returns (address) {
    return owner;
  }

Step 4 – Get started with examples

Once a Hedera hashgraph developer has completed a tutorial and have a basic understanding of writing transactions to the test network, they should start thinking about use cases for the platform. The Hedera network offers a variety of demo applications and starter projects for developers. However, it’s important to have a general idea of what the developer wants to build before choosing a starting point.

The Hedera use case pages can be a good source of inspiration for potential projects. These include payments, tokenized assets, and decentralized identity solutions. While these are just a few of the possibilities, the potential of the technology extends to many different industries. For more inspiration, developers can also check out the existing list of Hedera users to see what other projects are being built on the network.
