Everything You Need to Know about Nodes in Blockchain


If you imagine beads, you will see that they are made of countless elements. One of those elements in terms of computer science is called a node. Nodes are fundamental units of a data structure containing data and linking to other nodes.

A node can be represented by any electronic device as long as it possesses an IP address and connected to the Internet. One of the easiest ways to connect to most popular nodes is using NOWNodes service.

How Are Nodes Related to The Blockchain?

Nodes’ main function in Blockchain is supporting the network by storing a copy of a block. Sometimes they are used to process transactions. It is significant to mention that each cryptocurrency has its own node which allows it to keep track of tokens.

Basically, the functions of nodes come down to the following:

  • Nodes control the validity of transactions and are capable of accepting or rejecting them;
  • Nodes store blocks of transactions which refer to blockchain transaction history;
  • Nodes distribute transaction history to other nodes which may be necessary for synchronization with the blockchain;

How Are The Protocols Used for Connecting to Nodes?

Speaking of protocols, it is important to emphasize that they are a set of rules that governs how a system operates.

The main purpose of a protocol in blockchain is telling nodes how they should interact with each other. There are some particular protocols like Proof of Work, Proof of Stake, Ripple and etc. which operate in different ways yet come to the same result.

A node can be a communication endpoint or a point of communication redistribution, which links to other nodes. All the nodes on the network are thought to be the same, yet some nodes possess different roles in the manner in which they support the network and according to a protocol’s role. For example, not every node keeps a transaction history or a block copy.

What Are Full Nodes and Supernodes?

A full node is an outright list of all the transactions which have been implemented on a particular blockchain. The full node is designated to help cryptocurrency preserve the blockchain and keep the ledger distributed. Full nodes are usually compiled of smaller elements called light nodes which contain only partial history of transactions.

On the other hand, supernodes are specific features of some current blockchains. Besides validating and transmitting transactions, they can carry out other exercises like the execution of protocol operations and compliance with rules of a blockchain. Supernodes are usually always online and provide much more memory than full nodes.

How to Use Nodes in Practice?

Using nodes in real life is quite easy. All you need is a Bitcoin core client or any other and around 100 GB on your computer. For example, starting out with running a full node using NOWNodes means you will get full security and reliability. It sounds like an amazing way to find out if you like working with blockchain without putting much time and energy into creating your own cryptocurrency full node. But you have to know that keeping a multi-currency wallet requires maintaining a big number of special nodes to track the history of all possible transactions. However, it is quite easy to pick one currency you prefer or all of the listed ones without wasting time on constructing nodes for each cryptocurrency. 

Sum Up

Nodes play a substantial role in cryptocurrency protocols. All full, light and supernodes are equally essential to the safety and productivity of a cryptocurrency. If cryptocurrencies continue to grow rapidly, more and more people will switch from fiat money to cryptocurrencies. It means that more nodes will be needed to carry out a stable, safe and fast operation of blockchain transactions. If you need any help in setting up your full node or just would love to consult a support manager, we advise contacting us by email: [email protected] and not postponing this process.  Let’s drive crypto mass adoption together!
