Bitcoin Nodes: Why Is It Important To Know About This?

How to determine the security of a digital currency? One could easily assert that secure cryptos require to operate on a secure blockchain. However, this theoretical statement can have complicated applications in the real environment. One way to look at this matter is by linking security to validation. Each blockchain must contain an ideal transaction validation mechanism. When it is about the blockchain we generally talk about nodes. So today we are going to talk about Bitcoin nodes. 

This article aims to illustrate a very technical idea in a simple way. After evaluating its notion, it will be possible to address more complicated discourses on the matter. 

What Are Bitcoin Nodes?

Let us begin with a fundamental idea of the blockchain space: the P2P (peer-to-peer) network. Every Bitcoin block is part of a chain, portraying a digital ledger. But how can we be sure that hackers will not change the chain for their advantage?

Theoretically, hackers could steal BTC by changing the composition of a chain. This function, however, must overcome various obstacles, that include the P2P network. In practice, many linked computers preserve the format of the complete blockchain.

Each of these computers turns into a “node” in the Bitcoin blockchain. If a group of hackers plans to attack a node by changing the blockchain, the other nodes react instantly.

This reaction rebuilds the blockchain that is under attack to its original state, by bringing in a level of resilience into the system. In more general language, the role of BTC nodes is to regulate transactions in the network.

If we see the nodes as a team of system arbitrators, the whole matter looks more straightforward. The node communicates the altar to the other nodes whenever Bitcoin mining adds a block to the chain. However, anyone who tries to add an uneven knot to the chain will be unsuccessful in their attempt.  

Advantages Of Running A Bitcoin Node

Anyone following this article will probably have an important question at this point. Is it possible to change your computer into a node of the BTC network? If so, what are the advantages of this function? The short answer is that yes, anyone can operate a Bitcoin node. The advantages associated with the execution of a node are varied, and we summarize them below:


A block explorer is not an unidentified way of buying Bitcoins. Whenever we let a block explorer implement a transaction, we share sensitive data. A block explorer is aware of your IP address, which it can share with third parties. Assembling this data with your transaction history makes the issue clear. Running a Bitcoin node discards the problem as you are not required to share your data with anyone. Do not forget that whoever owns your IP address can be aware of your physical location. Hence, criminals may find out a hazardous consequence where wealthy BTC owners live.


You can hide your private key at the time of the transaction by operating your Bitcoin node. Since anyone who knows your private key can easily access your wallet, this is important to protect your savings. Hiding a key does not imply you will not sign a transaction since the BTC system would reject the function. You will always be required to use your digital signature, but no one will derive your private key.

No Middle Man

Another advantage comes with operating Bitcoin nodes, and crypto enthusiasts typically like it. The original aim of blockchain technology was to eliminate a centralized authority without any middleman. In this respect, the idea of depending on a third party to avail the Bitcoin network may look strange. However, if we discard the block explorer, several complexities can arise.

How can we verify that there are no more BTC in comparison to the maximum supply with a single computer? Knowing that this limit equals 21 million tokens, it is evident that the solution arrives from the P2P network. A constant connection between nodes, without any intermediaries, makes system maintenance faster and more direct. Reading the famous whitepaper that resulted in the birth of Bitcoin, this idea appears aligned with the notion of its founder.

Helps In A Stronger Infrastructure

Let us quickly go back to the matter of a hacker attack on a peer-to-peer network. A hypothetical case where a group of hackers could change the Bitcoin blockchain. Suppose the latest blockchain has ten nodes, entering the space as a tiny system. Then, in the BTC space, the attack on a single node would not impact the integrity of the blockchain.

There can be issues when hackers try to attack most of the nodes. Again, if we go back to the instance, a 6-node coordinated attack can create the validation of irregular blocks.

Hence, it is evident that the Bitcoin system needs many nodes. The good news is that the most famous anticipate is that there are more than 200,000 active nodes. Operating a new node in the system can raise the security of the Bitcoin blockchain.

How To Operate Bitcoin Nodes?

There are three varied methods to operate Bitcoin nodes. But before that, it is essential for you to note that there is no Bitcoin node reward if you operate one. There is no better way among those stated below, and the choice varies on your technical skills:

Local Execution

If you have a minimum of 350 gigabytes free on your computer, you can operate a Bitcoin full node locally. However, remember that your computer will require at least 2 Gb of RAM, a simple need in the modern world. Taking into account that you will be using your internet to connect to the P2P system, it is efficient to have a good contract with a service provider. The ideal choice, in this case, is to have an unlimited download and upload contract.

It is not hard to find a list of the minimum needs to operate a local system node online. After overcoming this hindrance, we can download the Bitcoin Core software and operate a node.

Taking Advantage Of The Cloud Technology

Everything we have stated about local execution functions is more simple on a cloud system. In this scenario, you do not have to worry about checking the technical features of your computer.

There are many common cloud computing services that have paid plans ideal for this aim. Generally, this is a more practical option than local execution. The only dimension to consider is the reliability of the cloud provider you select.

An Easier Option

If none of the above choices seem correct for you, there is an easier way as well to proceed. Some providers can take care of the complete pipeline for you. If you wish for more data about Bitcoin node buy, you can look up “Bitcoin node in a box solutions”.

However, do not forget that this choice does not eliminate the “middle man” in the system. You will operate a BTC node through a graphical interface, but you will be depending on a third party.


In this article, we discovered more data about the “referees” of the Bitcoin system. The nodes assure the integrity of the blockchain via the P2P infrastructure. But if you are wondering about Bitcoin node profit, there is no monetary reward in operating a BTC node. 

Each of us can operate Bitcoin nodes with several advantages that deserve a vital assessment. The system has introduced several ways to operate a BTC node, responding to broad industry demand. How you operate a Bitcoin node depends on our technical skills and preferences, without forgetting your aim. Eliminating the “middle man” stays one of the primary aims of the blockchain space.
