According to a recent study published by CoinDesk, blockchain technology development will continue to expand rapidly in the years to come. Those who are interested in blockchain technology would also have a greater desire to learn about it.

Blockchain will also find its way and explore modern uses in practically every vertical and horizontal. Blockchain technology is the underlying framework behind cryptocurrencies like Bitcoin and Ethereum, but it’s much more than that. A decentralized, distributed ledger enables secure, transparent, and tamper-proof data storage and transactions. Imagine a digital book shared across multiple computers, updated in real-time, and validated by a network of nodes – that’s essentially what Blockchain is.

In this beginner’s guide, we’ll take you on how to understand blockchain technology, including its history, key components, and applications. We’ll explore the benefits and limitations of Blockchain, as well as its potential uses in various industries, from finance and healthcare to supply chain management and voting systems.

Whether you’re a tech enthusiast, a business owner, or simply curious about the future of technology, this blockchain guide will equip you with the knowledge you need to navigate the world of Blockchain. So, let’s get started!

What is Blockchain Technology?

Blockchain is a shared digital ledger that is shareable and irreversible. It uses a network of computers to keep transactions or data in several locations. Here, every confirmed transaction is added to a section known as a block, which uses cryptography to link with other blocks in order to construct a chain.

If that explanation left you perplexed, let’s take a more basic look at blockchain technology for beginners. In other words, a blockchain is a collection of connected blocks that contain records. Now, let’s understand what exactly the difference between a database and a blockchain in brief!

Database vs. Blockchain

A database gathers a lot of data and organizes it tabularly so that users may simply and concurrently change it. Larger databases also employ servers with strong computers to process and store large amounts of data. Since a database is often owned by a business or a person, access to it is controlled and managed by them.

Blockchain, on the other hand, gathers data in blocks or groups that have a certain amount of storage. A block forms a chain with other blocks when its capacity is reached. The new block is comprised of all the newly created records that come after the next newly added block.

A blockchain is not owned by a single party like a typical database is; rather, anybody with authorization can access it. This is the reason behind its other name, decentralized system, as the blockchain is not managed by a single center. Distributed Ledger Technology (DLT) is the term used to refer to blockchain technology. It is a distributed ledger of records that enables peer-to-peer data sharing and transaction execution without the need for a central authority.

An unidentified person named Satoshi Nakamoto created blockchain technology as a public record for Bitcoin transactions. It attempts to guarantee that no one can tamper with a digital document by timestamping it. It facilitates the resolution of double record problems and safe asset transactions without the need for a third-party middleman like a bank or government agency.

This internet-based technology consists of several components, including software applications, databases, networked computers or nodes, and more.

What Make Up Blockchain’s Components?

The layers of the blockchain architecture include hardware, data, and networking components including nodes, applications, verification, and information distribution. Let’s examine a few of its elements for understanding blockchain technology basics.

1. Block

Blockchain, as previously said, is a collection of linked blocks that hold records or data. Additionally, the type of blockchain determines the data in each block. A blockchain used for banking, for instance, would comprise blocks with data like account numbers, account holders’ names, branch names, etc. A blockchain’s Genesis block is the first block, and every subsequent block hashed and encoded legitimate entries. A chain is formed by the cryptographic hashes of each block, which link to each other and to the preceding block in the same blockchain. Digital signatures are used in this iterative procedure to confirm the integrity of the earlier blocks.

2. Hashing

Similar to a fingerprint, a hash is specific to each block. It is a code that converts digital data into a lengthy string of characters and numbers by utilizing a mathematical formula. Each block and its contents are uniquely identified by this 64-digit hexadecimal number, and once a block is formed, any changes made to it will alter the hash. 

As a result, if an attacker modifies data in a block, the hash of that block is updated, but the previous block’s hash remains unchanged. As a result, all subsequent blocks become invalid and are traceable with ease.

3. Assets

Tangible and intangible assets are both possible. Intangible assets are non-physical things like intellectual property contracts, copyrights, patents, etc., whereas tangible assets are actual things like land, homes, machinery, etc. Curiously, money may be both material and immaterial.

4. Distributed Peer-to-Peer (P2P) Network

A distributed peer-to-peer (P2P) network without a central authority to regulate data facilitates every transaction on a blockchain. Anyone with access may join the blockchain, and each new machine added to the network becomes a node. As a result, if an attacker modifies data in a block, the hash of that block is updated, but the previous block’s hash remains unchanged. As a result, all subsequent blocks become invalid and are traceable with ease.

Blockchain Types

Blockchain Types

Depending on its kind, blockchain technology is used for a wide range of purposes by users. Thus, several kinds of blockchains include:

  • Public Blockchains

A decentralized, public network of several computers that anybody may use to request or check the correctness of a transaction is made possible by blockchain technology. It enables users to validate the data, add new blocks, and view every block on the blockchain. They make use of ideas like proof of stake or proof of labor since they are transparent and require high levels of security. Block miners receive cash compensation for validating transactions. The two primary uses of public blockchains are for bitcoin exchange and mining.

  • Private Blockchains

Private blockchains are controlled and centralized by an individual or group that also determines who may add new nodes, access the blockchain, and validate data. Private blockchains feature access limits and are closed systems in contrast to public blockchains. 

  • Consortium Blockchains

These permissioned blockchains are not governed by a single entity, but rather by a consortium of businesses or organizations. To benefit from greater security, they are more decentralized than a private blockchain. Access is restricted, and the consensus process is decided by the active nodes.

Additionally, when member nodes are authorized to start or accept transactions, it functions as a validator node to originate, receive, and validate transactions. In this case, consumers may more effectively and scalable move digital assets between blockchains.

  • Sidechains

A blockchain that runs concurrently to the main chain is known as a sidechain. Enabling consumers to transfer digital assets across two distinct blockchains enhances efficiency and scalability. The Liquid Network is an illustration of a sidechain.

How Does a Blockchain Transaction Work?

A blockchain transaction is a secure and transparent process that involves multiple steps, ensuring the data’s integrity and authenticity. Here’s a step-by-step breakdown of how a typical transaction occurs in a blockchain:

Step 1: Transaction Request

A user initiates a transaction, which can be a request for a specific action, such as transferring funds, updating records, or executing a smart contract. This request is then broadcast to the network.

Step 2: Distribution

The transaction is distributed across the peer-to-peer network, reaching nodes located globally. These nodes are responsible for verifying and validating the transaction.

Step 3: Validation

The nodes in the network validate the transaction using advanced algorithms and complex mathematical equations. If they find the transaction legitimate, the records are entered into blocks. This validation process ensures the integrity and authenticity of the transaction.

Step 4: Adding Blocks to the Blockchain

Once the transaction is validated, the newly created block is added to the blockchain. Each block contains a unique hash code that connects it to the previous block, creating a chain of blocks (hence the name blockchain). The hash code is generated using cryptography and encryption, ensuring that each block is tamper-proof.
