Dedicated nodes are designed as the most robust development solution. Unlike shared nodes, they are fully dedicated to their users, and no one else can access them. Basically, they act as a powerful server in full possession of its owner. Let’s focus on the dedicated Ethereum node as the most popular blockchain example and see how it can be used.
Why do You Need a Dedicated Node
For developers building applications on the Ethereum blockchain, running a dedicated node is crucial for seamless integration of blockchain functionalities. It allows developers to interact with the Ethereum network directly, minimizing latency and avoiding unforeseen complications.
This direct connection enhances the performance of decentralized applications (dApps) by providing real-time data access and transaction processing capabilities. Without a dedicated node, developers may experience delays and inconsistencies that can hinder user experience and application reliability.
Ordering a dedicated ETH node from services like GetBlock, while more expensive than using a shared node, is much more reliable. In addition, it’s still much cheaper than setting up the node by oneself.
Ethereum Node Types
When considering running a dedicated Ethereum node, it’s essential to understand the different types available, each serving specific purposes and requiring varying levels of resources. So, let’s start with it.
Full Nodes
Full nodes maintain a complete copy of the Ethereum blockchain, including all transactions and smart contracts. They are responsible for validating transactions and blocks, ensuring the integrity of the network.
Running a full node requires significant storage space, processing power, and bandwidth, as it must download and sync the entire blockchain. However, full nodes provide accurate blockchain data on demand and contribute to the overall security and decentralization of the Ethereum network.
Light Nodes
Light nodes operate differently from full nodes. They only download block headers instead of the entire blockchain. This makes them less resource-intensive and quicker to set up.
Light nodes rely on full nodes for additional information when needed, making them an efficient choice for users who want to interact with the Ethereum network without the overhead of maintaining a full node. They are ideal for personal computers, where resource constraints are a consideration. Still, a full node is preferable for serious Ethereum development.
Running an Ethereum Node
Setting up an Ethereum node involves several steps, including meeting hardware requirements, choosing a client software, and ongoing maintenance.
Requirements
To run an Ethereum node effectively, one needs specific hardware specifications:
- CPU: A powerful processor is essential for handling the blockchain client.
- RAM: At least 8 GB is required, while up to 32 GB is recommended.
- Storage: At least 2 TB of SSD storage is required for a full node.
- Internet: A stable connection with more than 10 Mbps bandwidth is necessary.
After that, one needs to choose and set up an Ethereum client.
Setting up a Client
There are execution and consensus clients, which are different in their destinations. Choose whether your node should maintain network consensus or interact with dApps, and select the client based on it. Locate it on the official Ethereum website, install it, and it will start synchronization with the blockchain’s current state. Last, adjust the server’s settings based on preferences for privacy, security, and performance.
Once the node is running, regular maintenance is crucial. Software must be updated regularly, performance monitored via specific tools, and data backups are needed to help in potential shutdowns and other problems.
Benefits of Running a Node
Running your own Ethereum node comes with several benefits.
- Decentralization: By contributing your node to the network, you enhance its resilience against attacks or failures.
- Privacy: A dedicated node allows you to interact with the blockchain without exposing your IP address or transaction details to third parties.
- Trustlessness: You can verify transactions independently without relying on external services.
Additionally, running a validator node allows you to earn rewards through staking ETH, further incentivizing participation in the network. Still, the time and money investments for that are usually very high, and an external provider may be a much better option.
Using an RPC Node Provider
While running your own dedicated Ethereum node has its advantages, it can be time-consuming and resource-intensive. Remote procedure call (RPC) node services like GetBlock offer access to fully operational nodes without the hassle of setup and maintenance. Dedicated nodes aren’t different from own servers of the highest quality, but require just monthly or yearly subscription payments.
Using an RPC provider with dedicated nodes allows developers to focus on building their applications rather than managing infrastructure. They obtain the RPC API endpoint, in the form of the URL, which can easily be integrated into code to trigger blockchain functionalities.
These providers offer high availability and scalability, ensuring that developers can enjoy many benefits associated with running their nodes. These include privacy and direct access to blockchain data without incurring significant costs or time commitments.
