A Beginner’s Guide to Understand Blockchain Technology

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?

• Blockchain architecture consists of:
  — Hardware
  — Data
  — Networking components
  — Nodes
  — Applications
  — Verification
  — Information distribution
• The blockchain is a collection of linked blocks that hold records or data.
• Each block is hashed and encoded with legitimate entries.
• Hashing is a mathematical formula that converts digital data into a unique 64-digit hexadecimal number.
• Any changes made to a block will alter the hash, invalidating subsequent blocks.
• Assets can be tangible or intangible.
• A blockchain uses a distributed peer-to-peer (P2P) network without a central authority.
• Anyone with access can join and become a node.

Blockchain Types

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

• Blockchain technology is a decentralized, public network of computers.
• Users can validate data, add new blocks, and view every block on the blockchain.
• Public blockchains are transparent and require high levels of security.
• Private blockchains are controlled by a single entity and feature access limits.
• Consortium blockchains are permissionless blockchains governed by a consortium of businesses or organizations.
• Sidechains are blockchains that run concurrently to the main chain, enhancing efficiency and scalability.

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:

1. Transaction Request: A user initiates a transaction, which is then broadcast to the network.
2. Distribution: The transaction is distributed across the peer-to-peer network, reaching nodes for verification.
3. Validation: Nodes validate the transaction using advanced algorithms and mathematical equations. Valid transactions are entered into blocks.
4. Adding Blocks to the Blockchain: Validated transactions are added to blocks and appended to the blockchain. Each block contains a unique hash code connecting it to the previous block, ensuring tamper resistance. The blockchain provides a secure and transparent record of transactions.

Business Benefits of Blockchain Technology

Blockchain technology offers numerous advantages for businesses across various industries, providing solutions that enhance efficiency, security, and transparency. Below are some key business benefits:

• Blockchain technology offers significant advantages across various industries.
• Immutable and encrypted records enhance security and reduce fraud.
• Transparency fosters trust and improves auditability.
• Cost efficiency is achieved by eliminating intermediaries and automating processes through smart contracts.
• Operational efficiency is enhanced through streamlined processes and real-time updates.
• Traceability is improved in supply chain management and product recalls.
• Blockchain as a service (BaaS) simplifies adoption, offers scalability, and is cost-effective.
• Regulatory compliance is strengthened through automated compliance and real-time reporting.
• Blockchain also enables innovative business models such as tokenization and decentralized finance (DeFi).

Use Cases of Blockchain Technology

Blockchain is currently becoming increasingly widely used in a variety of business sectors to provide them with advantages including security, anonymity, and transparency. Let’s examine a few of the applications for blockchain.

• Cryptocurrency

There are more cryptocurrencies than Bitcoin. Cryptocurrencies are virtual money that securely record transactions in a ledger via the use of powerful cryptography (blockchain). Its control is decentralized, and it is not issued by a central authority. In addition to Bitcoin, there are several other cryptocurrencies, including Dogecoin (DOGE), Namecoin (NME), Litecoin (LTC), Ethereum (ETH), Ripple (XRP), TRON (TRX), and many more. With the growing diversity of digital currencies, the concepts of multi-chain vs. cross-chain technology have become increasingly significant. Multi-chain technology involves multiple blockchains operating in parallel without interacting, while cross-chain technology enables interoperability between different blockchains, allowing seamless transactions across various cryptocurrency networks.

• Smart Contracts

Smart contracts are suggested contracts that are digital and blockchain-based. They don’t require communication with people to be implemented or enforced. It does away with the requirement for a middleman between two parties to a contract; the blockchain handles it.

• Banking and Finance

Because blockchain in fintech industry reduces costs and allows for quicker transaction speeds, several institutions, including UBS, are considering integrating it. Tokenization of different equities is also taking place, and new financial services such as Security Token Offerings (STOs) and Initial Coin Offerings (ICOs) are making their appearance. Properties such as real estate can be tokenized with the use of these services.

• Supply Chain

Blockchain is being used in supply chain industries including software development, food production, furniture manufacturing, and the mining of valuable commodities like diamonds.
