What is opBNB?

OpBNB is a layer-2 (L2) scaling solution for BNB Smart Chain (BSC). It enhances BSC by offloading transaction processing and resource usage while still posting data on the mainnet. This results in higher throughput and lower transaction fees, benefiting both developers and end users alike. 

So, how does opBNB work?

Users interact with opBNB by depositing assets from BSC and using contracts and applications on the L2 network. Sequencers aggregate transactions, compute state transitions and submit them to the roll-up contract on BSC. Provers generate cryptographic proofs that ensure the validity of state transitions. Verifiers then check the proofs to verify that the opBNB state is correct.

All in all, opBNB enables users to deposit and withdraw funds, use dapps and smart contracts, and access network data with high throughput and low transaction fees. As such, by leveraging opBNB, it’s possible to scale beyond the limitations of BSC, providing an improved experience for end users.

Benefits & Features of opBNB

Now, with an overview of what opBNB is, let’s explore some benefits and features of this L2 network:

• Optimistic Rollup Technology: OpBNB uses optimistic rollup technology, bundling multiple off-chain transactions into batches before submitting them to the main chain. This reduces the computational load on BSC, resulting in faster and cheaper transactions.

• High Throughput: OpBNB achieves higher throughput than BSC, supporting up to 5,000 transactions per second (TPS) as of 2024.

• Low Fees: By processing transactions off-chain and settling only the final state on BSC, opBNB offers low fees, making it ideal for micro-transactions and DeFi applications.

• Improved User Experience: With low fees and fast transaction confirmations, opBNB enhances the overall user experience of Web3, making dapp interactions more affordable and encouraging mass adoption.

• Robust Security: Despite processing transactions off-chain, opBNB maintains high security by relying on the underlying BSC network.

What are opBNB RPC Nodes?

OpBNB RPC nodes are computers, servers, and other similar devices that participate in the L2 network in some capacity. For instance, they are responsible for processing transactions, storing data, propagating blocks, and much more. The opBNB network consists of many nodes that together contribute to the blockchain’s security and integrity.

There are three main types of opBNB nodes: 

• Fast Node: Suitable for most dapps, fast nodes contain only the current state of the opBNB network. They are ideal for querying the current state and processing transactions.

• Full Node: Full nodes store recent trie data from the past 128 blocks, providing enhanced security and the ability to query historical data from specific blocks.

• Archive Node: Archive nodes store the complete historical trie data of the blockchain, making them essential for applications that require full chain history, such as block explorers.

What are opBNB RPC Nodes Used For?

OpBNB RPC nodes have many use cases. Here are three core examples:

• Transaction Processing: OpBNB RPC nodes are used to process transactions, making them pivotal for the network’s everyday operations.

• Data Storage: Nodes store smart contract and transaction data, which is crucial for the network’s integrity.

• Web3 Development: OpBNB RPC nodes act as gateways to the network, allowing users to seamlessly interact with the chain. Consequently, they are essential for building dapps, as RPC nodes allow developers to both read and write blockchain data from opBNB.

This gives you an overview of opBNB RPC nodes and their uses. In the next section, we’ll introduce Moralis—the industry’s leading node provider!

Tutorial: How to Set Up opBNB RPC Nodes in 3 Steps

Now that you’re familiar with Moralis’ node service, we’ll show you how to set up an opBNB node in three simple steps:

1. Sign Up with Moralis
2. Configure Your opBNB Node
3. Integrate Your opBNB Node

Step 1: Sign Up with Moralis

The first thing you’ll need to set up an opBNB node is a Moralis account. As such, if you haven’t already, make sure to sign up by clicking the ”Start for Free” button at the top right before moving on: 

Step 2: Configure Your opBNB Node

With an account at your disposal, go ahead and log in, navigate to the ”Nodes” tab, and hit ”+ Create Node”: 

Next, choose ”OpBNB”, followed by ”Mainnet”, and click ”Create Node”: 

Step 3: Integrate Your opBNB Node

That’s it; setting up opBNB RPC nodes doesn’t have to be more challenging than this when using Moralis! 

How to Call Your opBNB RPC Nodes

Now that you know how to set up opBNB RPC nodes with Moralis, we’ll show you how to use them in practice. More specifically, we’ll demonstrate how to fetch the native balance of an opBNB wallet using Ethers.js.

Before you start the tutorial, ensure you have the following ready:

• Node v.14+
• npm/yarn

Now, follow the five steps below:

• Step 1: Open your preferred IDE, create a folder, open a new terminal, and initialize a project with the command below:

npm init

• Step 2: Install Ethers.js with the following terminal command:

npm install ethers

• Step 3: Add "type": "module" to your “package.json” file:

• Step 4: Create a new “index.js” file and add the following code:

import { ethers } from "ethers";

const provider = new ethers.providers.JsonRpcProvider("YOUR_NODE_URL");

const address = "0xB661E5cA9f0079ac4B971489D72eCf67A7550cE2";

const balance = await provider.getBalance(address);
console.log("Balance: ", ethers.utils.formatEther(balance));

Configure the code by replacing YOUR_NODE_URL with one of your opBNB node URLs and change the address parameter to fit your query:

• Step 5: Run the script with this terminal command:

node index.js

In return, you’ll get the native balance of the specified address. Here’s an example of what it might look like:

Balance:  0.009918153154050728

Congratulations! You now know how to call your opBNB RPC nodes!

The Limitations of RPC Nodes

While it’s possible to use RPC nodes to interact with blockchain networks, it might not always be the ideal choice, especially when querying on-chain data. But why is that? Let’s explore three limitations of RPC nodes:

• Complex to Query: Nodes are challenging to query. Simple questions like “What ERC-20 tokens does wallet X hold?” require multiple requests and manual data compilation.

• Single-Chain: RPC nodes support only one blockchain at a time. This limitation complicates the development of cross-chain dapps, requiring a separate node for each chain.

• Raw Data: Nodes deliver raw blockchain data. Before you can use it, you must index, interpret, decode, and format the information, which is time-consuming and resource-intensive.

So, what is the alternative?

To avoid these issues, your best choice is to leverage an API provider like Moralis. With our intuitive interfaces, you can query indexed and decoded data straight out of the box with just a few lines of code. Want to learn more? Join us in the next section as we dive deeper into Moralis!
