Unlock the Power of RPC Nodes and Create Your Own Dapp on XDC Network!

Have you ever wondered how to develop decentralized applications on a blockchain network? You may have heard about RPC nodes, but do you know how to set one up and use it to create your own decentralized applications (Dapps)? This article will explain what RPC nodes are and how they can be used to create powerful Dapps on XDC Network.

Introduction to RPC Nodes

RPC nodes are essential components of a blockchain network. They are responsible for receiving, processing and validating requests from users and other nodes. By using RPC nodes, developers can create distributed applications (Dapps) that run on the blockchain, allowing users to interact with the network in a secure and trustless manner.

RPC nodes allow developers to access the blockchain’s data, send transactions, and execute smart contracts. They also provide a way for developers to interact with the underlying blockchain technology without having to write complex code. This makes it easier for developers to create and deploy Dapps with minimal effort.

RPC nodes are also used to validate transactions and maintain the blockchain’s consensus mechanism. Without them, the blockchain network would be prone to attack and manipulation.

What is XDC Network?

XDC Network is a permissionless blockchain network that provides developers with the tools they need to build and deploy decentralized applications. XDC Network is powered by the XDC Protocol, a set of rules and protocols that allow developers to create and deploy Dapps on the network.

The XDC Protocol is powered by a consensus mechanism known as Proof of Stake (PoS), which enables the network to process transactions quickly and securely. The XDC Protocol also includes features such as smart contracts, decentralized exchanges, and staking rewards.

Benefits of using RPC nodes

Using RPC nodes to develop Dapps on XDC Network provides developers with several benefits. Firstly, RPC nodes allow developers to access the blockchain’s data without having to write complex code. This makes it easier for developers to create and deploy Dapps with minimal effort.

RPC nodes also provide developers with a secure and trustless way to interact with the blockchain. This ensures that the data and transactions on the blockchain are safe from manipulation and attack.

Using RPC nodes also ensures that the Dapps created on XDC Network are highly scalable. This is because the nodes are able to quickly process requests and validate transactions on the blockchain. This makes it easier for developers to create and deploy applications that are able to handle a large amount of traffic.

Finally, using RPC nodes to develop Dapps on XDC Network allows developers to take advantage of the network’s low transaction fees. This makes it easier for developers to create and deploy applications that are cost-effective and efficient.

How to set up an RPC node

Setting up an RPC node on XDC Network is a relatively simple process.
Prerequisites
Before we get started, make sure you have the following prerequisites:

  • A server or cloud instance with at least 16 GB of RAM and 500 GB of storage.
  • Ubuntu 20.04 LTS operating system.
  • Basic knowledge of the Linux command line.
  • Step:-1 setting up the full node with the Bootstrap command
sudo su -c “bash <(wget -qO- https://raw.githubusercontent.com/XinFinOrg/XinFin-Node/master/setup/bootstrap.sh)" root
Enter fullscreen mode Exit fullscreen mode

Example:-

$ sudo su -c “bash <(wget -qO- https://raw.githubusercontent.com/XinFinOrg/XinFin-Node/master/setup/bootstrap.sh)" root
[sudo] password for user: 
Please enter your XinFin Network (mainnet/testnet/devnet) :- mainnet
Your running network is mainnet
Please enter your XinFin MasterNode Name :- Demo_Server 
Your Masternode Name is Demo_Server
Enter fullscreen mode Exit fullscreen mode

Step:2 Setting up the full node with docker

Clone repository

git clone https://github.com/XinFinOrg/XinFin-Node.git
Enter fullscreen mode Exit fullscreen mode

Enter XinFin-Node directory

cd XinFin-Node
Enter fullscreen mode Exit fullscreen mode

Install docker & docker-compose

sudo ./setup/install_docker.sh
Enter fullscreen mode Exit fullscreen mode

Update the .env file with details Create a .env file by using the sample — .env.example

Enter either your company or product name in the INSTANCE_NAME field.

Enter your email address in the CONTACT_DETAILS field.

cd mainnet # testnet
cp env.example .env
nano .env
Enter fullscreen mode Exit fullscreen mode

Start your Node

cd mainnet
sudo docker-compose -f docker-compose.yml up -d
Enter fullscreen mode Exit fullscreen mode

To stop the node, or if you encounter, any issues use

sudo docker-compose -f docker-compose.yml down
Enter fullscreen mode Exit fullscreen mode

Attach XDC Console:

cd mainnet
sudo bash xdc-attach.sh
Enter fullscreen mode Exit fullscreen mode

Follow the snapshot steps to get your full node to sync faster

After downloading the snapshot, monitor your node on the stats page. Once your node is fully synced, you can start using the dedicated RPC for your Dapp. Please note that the RPC port used is 8989, and for WebSocket, the port used is 8888.

To enable the 0x prefix RPC Endpoint, you can add the flag “ — enable-0x-prefix” to your “startnode.sh” script. This will allow the RPC Endpoint to recognize and process 0x-prefixed addresses.

Building a Dapp on XDC Network using RPC nodes

Once the RPC node is set up and connected to the XDC Network, developers can start building their own Dapps. The first step is to create a smart contract. This is done by writing code in a language such as Solidity. The smart contract code can then be compiled and deployed to the XDC Network using the XDC CLI.
Once the smart contract is deployed, the next step is to create the frontend of the Dapp. This is done by writing code in a language such as HTML, CSS, and JavaScript. The code can then be compiled and deployed to the XDC Network using the XDC CLI.

Once the frontend is deployed, the Dapp is ready to be used. Developers can then start interacting with the Dapp using the RPC node. This allows them to send transactions to the Dapp, query the blockchain’s data, and execute smart contracts.

Advantages of using XDC Network

Using XDC Network to develop Dapps has several advantages. Firstly, the XDC Protocol is powered by a consensus mechanism known as Proof of Stake (PoS). This ensures that the network is secure and resistant to attacks and manipulation.

The XDC Protocol also includes features such as smart contracts, decentralized exchanges, and staking rewards. This makes it easier for developers to create and deploy applications that are secure, trustless, and cost-effective.
Finally, the XDC Protocol is highly scalable. This makes it easier for developers to create and deploy applications that can handle a large amount of traffic.

What are the requirements for deploying a Dapp?

To deploy a Dapp on XDC Network, developers need to have the following:
• A computer with an internet connection
• The XDC Network software
• The XDC Protocol
• The XDC Network node software
• The XDC CLI
• A configuration file
Once the requirements are met, developers can start building and deploying their Dapps on XDC Network.

Types of Dapps that can be built on XDC Network

Developers can use XDC Network to build a variety of different types of Dapps. These include games, digital wallets, exchanges, and other financial services. Developers can also use XDC Network to build applications that utilize smart contracts, such as decentralized autonomous organizations (DAOs) and supply chain management systems.

Troubleshooting tips for setting up an RPC node

If you are having trouble setting up an RPC node on XDC Network, here are some troubleshooting tips:
• Make sure that your computer is connected to the internet. • Make sure that you have the correct version of the XDC Network software.
• Make sure that you have installed the necessary dependencies.
