Is Hedera hashgraph a good fit for building DeFi dApps?

Imagine a world where transactions are processed in the blink of an eye, data is shared securely and efficiently, and everyone has a say in how things are run. This is the world of Hedera Hashgraph, a revolutionary new distributed ledger technology changing how we think about online transactions and data sharing. Often considered one of the faster and more secure alternatives to the blockchain, the Hedera Hash graph’s key differences with blockchain are the Virtual Voting Consensus and aBFT used as the fault-tolerant mechanism for security. We have already learned the basics and core concepts of Hedera Hashgraph. This article will delve deeper into Hedera Hashgraph and explore the possibilities of  Hedera Hashgraph for DeFi dApps.

Brushing up basics

Hedera Hashgraph is a distributed ledger technology used to build decentralized applications. The technology is designed to be fast, secure, and fair. It can be used for various use cases, including digital currency, supply chain management, voting systems, etc. It uses a novel consensus mechanism called the “hashgraph consensus algorithm,” which is based on the principles of gossip protocol and virtual voting, to achieve a high level of security and performance.

Hedera Hashgraph’s network services are essential to the platform’s utility, allowing anyone – from individual developers to large companies- to sign up anonymously and build applications on the network for various purposes. These applications can range from startups to investments and have the potential to be used by anyone from small businesses to Fortune 500 companies.

Feasibility of Hedera Hashgraph for DeFi dApps

Hedera Hashgraph is a game-changer in the field of DLT, offering a unique combination of high throughput, low latency, and secure and fair consensus. But is it good for building DeFi dApps? Let’s explore the various use cases and applications of Hedera Hashgraph and help you determine if it is the best choice for your DeFi project. There are several use cases for Hedera Hashgraph, where it may be a better choice than traditional blockchain technology. Why Hedera can be a good fit for DeFi apps;

• High-throughput: One of the main advantages of Hedera Hashgraph is its high throughput, which allows for a large number of transactions to be processed per second. This makes it well-suited for use cases such as micropayments, where many transactions need to be processed quickly.
• Decentralized applications: Hedera Hashgraph allows for the creation of decentralized applications (dApps) that can be used for a variety of purposes, such as digital identity, supply chain management, and voting systems. The platform’s high throughput and low latency make it well-suited for these applications.
• Compliance and regulatory use cases: Hedera Hashgraph allows for the creation of digital identities that can be used to comply with know-your-customer (KYC) and anti-money laundering (AML) regulations. This makes it well-suited for use cases such as banking and finance, where compliance is a major concern.

When compared with blockchains, Hedera Hashgraph offers several advantages, such as:

• Fair ordering: The Hashgraph algorithm ensures that all transactions are processed in fair order, regardless of the node that initiated the transaction. This is different from traditional blockchain technologies, where the order of transactions can be influenced by the miner who includes the transaction in a block.
• High throughput: Hashgraph can process thousands of transactions per second, compared to traditional blockchain technologies, which can only process a few transactions per second.
• Low latency: Hedera Hashgraph allows for near-instant confirmation of transactions, compared to traditional blockchain technologies, which can take several minutes or even hours for a transaction to be confirmed.
• Decentralized governance: Hedera Hashgraph allows for a decentralized governance mechanism where all users can participate in the decision-making process.

Building a DeFi dApp with Hedera Hashgraph

Hedera Hashgraph can be used to build a DeFi dApp. The below steps will give you an idea of how to start the defi development.

1. Create a Hedera account by visiting the Hedera Portal website.
2. Download and install a Hedera Hashgraph wallet, such as th+e Hedera Wallet, which will allow you to securely store and manage your HBAR.
3. Connect to the Hedera network using one of the available SDKs (Software Development Kits), such as the Hedera SDK, which can be found on the developer portal.
4. Build and deploy your decentralized application (dApp) on top of the Hedera network using the SDKs, smart contract languages like Solidity, and developer tools.
5. You can now use your dApp to securely and quickly perform transactions, create and manage smart contracts, and more.

pragma solidity ^0.8.0;

contract SimpleLoan {

    address payable public lender;
    address payable public borrower;
    uint public loanAmount;
    uint public interestRate;
    uint public loanDuration;
    bool public loanActive;

    constructor() public {
        lender = msg.sender;
        loanActive = false;
    }

    function lend(address payable _borrower, uint _loanAmount, uint _interestRate, uint _loanDuration) public {
        require(loanActive == false);
        require(msg.sender == lender);
        borrower = _borrower;
        loanAmount = _loanAmount;
        interestRate = _interestRate;
        loanDuration = _loanDuration;
        loanActive = true;
        borrower.transfer(loanAmount);
    }

    function repay(uint _repaymentAmount) public {
        require(loanActive == true);
        require(msg.sender == borrower);
        require(_repaymentAmount >= loanAmount + (loanAmount * (interestRate / 100)));
        lender.transfer(_repaymentAmount);
        loanActive = false;
    }
}

This above code is an example smart contract that allows a lender to lend a certain amount of money to a borrower at a given interest rate for a specified duration.

Remember that you need some understanding of decentralized application development and blockchain concepts to develop a dApp. If you need to become more familiar with these concepts, you could seek help or learning resources to get into them.

Bottom Line

In summary, Hedera Hashgraph is a distributed ledger technology that offers several advantages over traditional blockchain technologies, such as high throughput, low latency, fair ordering, and decentralized governance. These advantages make it well-suited for a wide range of DeFi use cases.
