In the fast-evolving cryptocurrency space, reliable access to blockchain networks is essential for businesses like crypto wallets and exchanges. Full Nodes play a key role in ensuring this reliability, with the Linea RPC Full Node being a valuable tool. This article explores the benefits of Linea RPC Full Nodes and provides a guide: how to use NOWNodes to enhance your crypto transaction capabilities.
What is a Linea RPC Full Node?
A Linea RPC (Remote Procedure Call) Full Node is a server that holds a complete copy of the Linea blockchain ledger. It maintains a real-time record of all transactions. This node is essential for the Linea network, as it validates transactions and blocks based on the network’s consensus rules. These nodes are the backbone of the Linea ecosystem, providing an interface for developers and businesses to interact with the blockchain, query data, and broadcast transactions.
Advantages of Accessing a Linea Network
Linea is a zkEVM L2 network, meaning that it combines zk-rollups with EVMs (Ethereum Virtual Machines). A zero-knowledge approach enables the network to demonstrate to the Ethereum network that all activities on the Linea network are indeed occurring, without the need to provide a comprehensive history of every single transaction and verify them individually. At the same time, Linea is EVM-compatible which enables developers to communicate with the network with commands and tools similar to Ethereum’s.
Accessing a Linea Network through its Full Node offers numerous benefits, especially for crypto wallets and exchangers:
- High Scalability: With its advanced consensus mechanisms, Linea ensures that your applications can scale to meet user demand without compromising on speed or security.
- Utilization of the Ethereum JSON-RPC API: For those developers who are familiar with Ethereum, getting into Linea would be as easy as possible. Being an ETH Layer 2 zk-rollup scaling solution Linea has similar commands as an Ethereum, meaning that the developer experience is identical to building on Ethereum itself.
- Interoperability: Designed for seamless interaction with other blockchains, Linea facilitates easy data and asset transfer, expanding your project’s reach.
- Low Transaction Costs: Enjoy minimal fees for transactions, making it economically viable to build and run dApps with high transaction volumes.
- Enhanced Security: Linea’s state-of-the-art cryptographic techniques provide a secure environment for developing and deploying smart contracts and cryptocurrencies.
- Vibrant Community: Tap into the wealth of knowledge and support from Linea’s active and growing developer community, fostering collaboration and innovation.
Moreover, the Linea ecosystem has a wide range of use cases offering Web3 developers a brand new experience. From creating crypto wallets, or building Web3 games to minting NFTs, anything you might need Linea has to offer.
Access a Linea Node with NOWNodes
The easiest, most secure, and also the cheapest way to access a Linea full node is to use third-party node providers just like NOWNodes. In this case, you don’t need to worry about running your own node, which is also time-consuming, very resource-expensive, and potentially costly.
You can access a Linea RPC node with NOWNodes by following these simple steps:
- Create a profile on the NOWNodes website. You will need to provide your email and create a password.
- After choose a tariff plan. There are different plans that fit any Web3 needs.
- The next step is to choose the desired blockchains to access. By utilizing a free plan you will be provided with the option to choose 5 blockchain networks. If you are looking for the Linea mainnet, just navigate downwards and click on the button located in front of the section labeled “Linea” on the page.
- On the “DASHBOARD” page find the “ADD API KEY” button. Here, you can generate a Linea API key.
- Finally, use the methods from the “DOCS” page to connect to the Linea full node and interact with the Linea mainnet network.
When you’re done with the registration process and the API environment is ready to be used, it’s time to make some HTTP requests. Use the general endpoint linea.nownodes.io as the base URL for your requests and authenticate it by including your Linea API key.
As was stated before, most of the Linea API methods are borrowed from Ethereum. So, to interact with the Linea blockchain use Ethereum JSON-RPC API methods. However, there are some extra Linea-specific API methods that we’ll explain in the next paragraph.
How to Interact with the Linea RPC Nodes? Linea API methods
Being Ethereum’s zkEVM Layer 2 network, Linea is ETH-compatible. That could be a great advantage for developers who have some experience with Ethereum because Linea offers the same user experience, complementing it with the unique linea_estimateGas API methods.
There are a variety of methods borrowed from Ethereum that you can utilize to interact with the Linea network. We’ll provide a few most commonly used ETH methods available on Linea. Let’s start with the example of eth_getBalance method which can be used to check an account’s ETH balance. Here’s a sample request:
curl --location 'https://linea.nownodes.io/<your_api_key>' \
--header 'Content-Type: application/json' \
--data '{
"jsonrpc": "2.0",
"method": "eth_getBalance",
"params": [
"Your_address",
"Latest"
],
"id": 1
}'The response for this method will be the balance of the specified address in Wei (Ethereum’s smallest denomination).
Additionally, another basic method is eth_blockNumber. Here’s a sample request for the eth_blockNumber method:
curl --location 'https://linea.nownodes.io/<your_api_key>' \
--header 'Content-Type: application/json' \
--data '{
"jsonrpc": "2.0",
"method": "eth_blockNumber",
"params": [],
"id": 83
}'This method returns the latest block number of the blockchain in hexadecimal numbers. For example, the block number 0x248ead means that the block is the 2395821st in the blockchain.
Linea adopts the Ethereum EIP-1559 model for gas pricing. Yet, being a layer 2 blockchain, it offers a more consistent and economical approach to handling transaction fees. If you’re willing to get more sophisticated and accurate data for your estimated transaction fee calculation, linea_estimateGas method is a perfect tool. You may check the API reference for this method here.
Conclusion
For blockchain enterprises, like crypto wallets and exchangers, the efficiency and reliability of transactions are non-negotiable. By accessing and utilizing Linea RPC Full Nodes through services like NOWNodes, you can ensure a high level of service quality for your users. This not only enhances transaction capabilities but also contributes to the overall health and decentralization of the Linea network. Start leveraging the power of Linea RPC Full Nodes today to elevate your crypto projects to the next level.
