Article source

In the world of blockchain technology, understanding the various types of nodes is like holding the keys to a treasure chest of opportunities.

These nodes play a pivotal role in the functioning and security of blockchain networks.

In this comprehensive guide, we will dive deep into the universe of blockchain nodes and unlock the secrets to success in this dynamic space.

What is a node? In the blockchain, the concept of “node” is often used to refer to an independently operating component in the blockchain network.

Each node represents a computer or a computer system that is connected to the blockchain network and is involved in the process of building and maintaining the system.

A node in the blockchain can have different functions, depending on the type of blockchain and its role in the network.

Some of the key functions of a node in the blockchain include:

Data storage and synchronization: Nodes store blockchain data as blocks and transactions and synchronize information with other nodes in the network.

Transaction Verification: Node checks and verifies the validity of transactions in the blockchain by applying defined rules and algorithms.

In the Proof of Work (PoW) blockchain, a number of nodes called mining nodes, or miners, engage in the mining process to create new blocks in the blockchain.

Validate and contribute to the decision: In a blockchain based on Proof of Stake (PoS) or other authentication mechanisms, nodes participate in transaction verification and contribute to decision-making in the system.

Information transmission: Nodes transmit information, including new transactions and verified blocks, to other nodes in the network to maintain the synchronisation and integrity of the blockchain.

Creating decentralisation: One of the strengths of blockchain is decentralisation. Each node plays a role in decentralisation by checking and ensuring compliance with network rules and protocols.

The types of nodes in the blockchain may vary depending on the structure and regulation of the network, but the basic function of the node is to participate in the construction, maintenance, and operation of the blockchain network.

10 Common Node TypesNodes play an important role in creating and operating the network, validating and processing transactions, ensuring data integrity, and contributing to the expansion and development of the blockchain.

Here is an overview of the 10 most common types of nodes:

Full Nodes: The full nodes in the blockchain network maintain a synchronous copy of the entire blockchain and process transactions.

Pruned Full Nodes: A minimalist version of the full nodes, they store only a fraction of the blockchain data, saving storage space.

Archival Full Nodes: The full nodes store the entire transaction history in the blockchain network, helping to research and explore historical data.

Miner Nodes: A dedicated node for mining and renewing blocks in the blockchain network.

Authority Nodes: Authorised and authorised nodes to participate in the transaction evaluation and validation process, ensuring the integrity of the network.

Staking Nodes: The nodes involved in the staking process contribute to the security and maintenance of the blockchain network.

Light Nodes: As a lightweight version of Full Nodes, they store only a small fraction of the blockchain data and rely on other nodes to query the data.

1. Pruned Full Nodes

Pruned Full Nodes is a type of node in the blockchain network that is capable of storing only a fraction of the transaction history of the blockchain, while retaining the characteristics of a full node.

This is achieved by removing unnecessary historical data during transaction verification and building new blocks.

The primary function of Pruned Full Nodes is to reduce the required storage capacity of a full node while maintaining the ability to verify and authenticate transactions in the blockchain network.

Instead of storing the entire transaction history, Pruned Full Nodes only stores the information necessary to verify the validity of the current transaction and the current status of the blockchain.

The cutting process is carried out by removing unnecessary old blocks after the blocks have been verified and long enough to ensure that the transactions in them have become unchangeable.

These blocks are no longer needed to verify the validity of new blocks and existing transactions.

By removing these blocks, Pruned Full Nodes significantly reduces storage capacity while retaining network engagement and transaction verification.

Some of the benefits of Pruned Full Nodes include:

Saves storage space: Pruned Full Nodes reduces the required storage capacity compared to a traditional full node, helping to reduce the amount of data that needs to be downloaded and stored on the network.

Increased synchronisation speed: As storage capacity decreases, Pruned Full Nodes sync process can be faster, allowing the node to quickly join the network and verify transactions.

Decentralised input: Pruned Full Nodes still has the ability to verify and authenticate transactions, ensure the decentralisation of the blockchain network, and check the validity of data.

While Pruned Full Nodes reduce storage capacity, they retain the functionality of a full node, such as verifying transactions and contributing to the building of new blocks.

This means that Pruned Full Nodes can function as a normal full node, while saving storage space and increasing the performance of the blockchain network.

One important note is that Pruned Full Nodes may lose the ability to fully retrieve the transaction history of the blockchain.

However, this does not affect the ability to verify and authenticate new transactions or new blocks.

Pruned Full Nodes can still rely on other full nodes in the network to get the necessary information if you need to search for detailed transaction history.
