The complete guide to what blockchain technology?

If you read financial and technical news, you will surely come across the term “blockchain”.


Want to gain in-depth knowledge on this topic, this short guide will help you understand what this technology is and give an overview of its benefits and how it works.

What blockchain

what blockchain technology

Blockchain is a peer-to-peer, decentralized distributed ledger technology that makes the records of any digital asset transparent, immutable, and works without the involvement of any third-party middleman.

Blockchain, as we have told us, is like a book with numbered pages, with the imposition of not writing on the next page until the end of the page before it, and the need for the previous page to be sealed with the same seal as the next page. This ledger becomes invalid in the event that one of the already written papers is changed or attempts to falsify or tear it. The same applies to the blockchain, as it counteracts attempts to change previous transactions and prevents the possibility of falsifying a previous approved transaction.

Blockchain is an emerging and revolutionary technology that has attracted a lot of public attention due to its ability to reduce risks and frauds in a scalable way.

A decentralized network provides multiple advantages over a traditional centralized network, including increased system reliability and privacy. Additionally, such networks are much easier to scale and manipulate as there is no true single point of failure. The reason for the distribution and decentralization of the blockchain is interconnection and distributed processing. 

The P2P architecture of blockchain networks provides many advantages such as increased security compared to traditional networks based on a single server at the client.

 A distributed P2P network, combined with majority compatibility requirements, provides a relatively high degree of resistance to malicious activity.

Blockchain and Bitcoin: How are they related?

Although the emergence of blockchain has revolutionized the world, many people are still confused about these two terms, and some see them as one.

 Thus, it is important to clarify how these terms differ and how are they related?

Bitcoin is a cryptocurrency, and it is an application of the blockchain, while the blockchain is simply the underlying technology upon which Bitcoin is built .

 So if you're working on the blockchain and learning about the blockchain technology, you're not actually learning about cryptocurrencies but you're learning how cryptocurrencies work. 

Blockchain mechanism:

A blockchain can be defined as a shared ledger, which allows thousands of connected computers or servers to maintain a single, immutable and secured ledger. 

The blockchain can process users' transactions without involving any third-party intermediaries.

In order to make transactions, all one needs is to have their wallet.

A blockchain wallet is nothing but a program that allows a person to spend cryptocurrencies like bitcoin, ethereum, etc. 

These wallets are secured by encryption methods (public and private keys) so that the individual can fully manage and control his transactions.

As for the way the blockchain network works, it is as follows:

Initially, when a user creates a transaction via the blockchain, a block representing that transaction will be generated.

 Once a block is created, the requested transaction is broadcast over a peer-to-peer network, which consists of many computers running the same software, known as nodes, which then validate the transaction.

 The verified transaction could include cryptocurrency, contracts, records, or any other information of value.

Once a transaction is verified, it is combined with other blocks to create new blocks of data for the ledger. It is important here to note that with each new transaction, a secured block is created, which is linked together using cryptographic principles. When a new block is created, it is added to the existing blockchain to confirm that it is secured and immutable.

Blockchain types:

There are three main types of blockchain networks, which do not include traditional databases or the distributed ledger technology (DLT) that is often confused with blockchain networks.

As for the types of blockchain networks, they are as follows:

Public blockchains such as Bitcoin and Ethereum.

Private blockchain networks such as Hyperledger and R3 Corda.

Hybrid blockchains such as Dragonchain.

In subsequent articles in the section on digital currency trading education,  we will discuss in detail the nature and advantages of each of these networks.

Benefits of using blockchain technology:

Well, by reaching this line, you will have gained a lot of information about blockchain technology, which you seem interested in knowing its finest details, below we will explore its benefits.


In a traditional database, you must trust the system administrator not to alter the data. But with the blockchain, there is no possibility to change or erase the data. 

The data inside the blockchain is permanent and cannot be deleted or reverted.


Centralized systems are not transparent, while the blockchain (a decentralized system) provides complete transparency. 

Through the use of blockchain technology, organizations and companies can enjoy a fully decentralized network as there is no need for any central authority, thus improving the transparency of the entire system.

As the transactions on the blockchain, specifically the public blockchain such as the Bitcoin blockchain, are in front of the eyes of the world as a whole, where the progress of transactions, the amount of bitcoin transferred, and the public addresses sent and received can be seen normally. However, there are private blockchain networks with which camouflage protocols are integrated and covering public addresses and transaction amounts, for example digital currencies of a privacy nature, such as: Monero XMR.

Availability and ease of use:

Unlike centralized systems, blockchain is a decentralized P2P network system which is highly available due to its decentralized nature. Since in a blockchain, everyone is on a P2P network, and everyone has a working computer, so even if one person or device goes down, other peers can still work normally.

High protection:

This is another major benefit offered by the blockchain technology. Blockchain technology is supposed to provide high security because all blockchain transactions are encrypted with strong encryption. Therefore, the blockchain is physically secure and provides integrity. Hence instead of relying on the third party, you need to put your trust in the encryption algorithms.

In conclusion, it can be said that learning the blockchain and programming on it has become easy, and all thanks to online training courses, such as the training courses offered on the  Trader website.

Many analysts believe that blockchain technology is a technology that is here to stay and that will change the digital world in which we live, through the various uses and applications, from the possibility of preserving copyrights to tracking solutions and ensuring the authenticity of the product to encrypted digital currencies characterized by high speed of transactions and semi-fee or not.
