What Is Blockchain? What Is It? Blockchain unction?

Blockchain technology has been around for a while since the 1990s. It was only presented in 2008 as the distributed ledger that underlies Bitcoin transactions. Blockchain is growing stronger and more popular for users, have ever thought "How does blockchain work?". This article will help answer that query.

What's Blockchain?

Blockchain is a combination of the phrases "block" and "chain." It is a decentralized platform created to promote decentralization, transparency, and data security.

There are a variety of definitions for blockchain. As per IBM, Blockchain is a shared ledger, which is unchangeable and helps record transactions and identify assets within a business network.

The Blockchain's Structure

Each block includes 3 main parts:

Data: Data can be various types of information based upon the network of blockchain.

Hash of the block currently in use It is the unique identification number for each block. Each block is unique in its hash, which is our fingerprint.

The hash of the block before It is this hash that allows the blocks to link and form chains. The first block is known as the basic block since it does not have any connection with the other blocks.

Different types of Blockchain Networks

1. Public Blockchain

The blockchain is accessible to anyone and controlled by no one. Anyone who has a computer and internet access can join the network. The public blockchain to transfer and mine cryptocurrency.

Bitcoin and Ethereum are two examples of blockchains that are public.

2. Private Blockchain

As with the private blockchain, it's only accessible to a select group of authorized users. One organization is the sole one that controls the private blockchains that operate within a private network.

3. Hybrid Blockchain

It's a blend of an open blockchain network as well as an encrypted blockchain network. It will select those who are part of the blockchain, and determine which transactions are made public.

4. Consortium Blockchain

Like a hybrid blockchain network, it has both private and public components. However, different organizations manage the blockchain network.

While these kinds of blockchains may be more difficult to establish they do offer better security.

What is the Function of Blockchain?

Blockchain technology can automatize a lot of the following processes:

1. Record Transaction

In the beginning, a user of the blockchain network operates. The transactions are recorded as a block of information and contain various information.

2. Reach Consensus

Blockchain does not operate as a centralized entity, and transactions are stored in a peer-to-peer network that is verified. Due to this, the other participants in the blockchain network can validate the authenticity of transactions.

A consensus mechanism is responsible for the process of verification. The transaction is sent through the nodes for verification. When the vast majority of network members agree the transaction is genuine the transaction will be confirmed.

3. Linking Blocks

After consensus is achieved the transactions are recorded in the form of a block. It equates to a spot in a ledger. It will also include a timestamp as well as an ID that is unique to protect it from any modifications.

This block is formed and then connected to the previous block via a cryptographic hashing protocol. Then, a new block will be created as an interlink with this one. This way it makes an entire blockchain.

4. Share Ledger

As soon as data are updated in the ledger system, then all participants of the network are updated and shared in real-time. The data cannot be changed or reversed. Also, a new transaction is possible however the transaction from before remains unaltered.

The question, "How does blockchain work?" likely won't be the primary concern of many. This article should provide you with more information on blockchain, as well as provide an overview of the way it operates.
