Blockchain technology has reorganized and transformed the world at large, changing how we see and perform different transactions daily. And at the very core of this blockchain technology is its driving force, Web3.

Web3, the latest evolution of the internet, uses blockchain technology alongside other systems to decentralize several industries be it marketing, banking, and even the supply chain business.

Understanding Blockchain Technology

Before I go on to define the term “blockchain technology” and explain how it operates, a few terms must be defined:

Decentralization is the removal of control from a single entity, giving this power to multiple others (a network of computers in this case).

A ledger is a record-keeping system that stores and manages financial transactions.

A block is a group of transactions (which may be financial) recorded on a blockchain.

Cryptographic Hash is a mathematical algorithm that takes in an input and returns a fixed-size string of bytes known as the hash value. Each hash value is unique to the input data and so it is used to create a unique ID for each block making it secure.

And now, when I say that Blockchain Technology uses a decentralized ledger, where transactions are recorded in blocks; each block linked to the previous using cryptographic hashes, making each data stored immutable”, you understand right?

The concept of Blockchains was popularized by the persona under the codename Satoshi Nakamoto when he released the Bitcoin Network in 2009. This network handles the transfer of Bitcoin assets securely.

Key Features of Blockchain Technology

The revolutionary approach brought about by this technology has many features that make it valuable enough to be used across various industries. These features include:

Decentralization

Blockchains operate under the theme of decentralization as financial transactions or blocks, are not kept under a single entity but are rather kept across various systems or nodes. This enhances security and at the same time improves the level of transparency garnering the user’s trust.

Immutability

Each block on the blockchain contains a reference to the previous block through a cryptographic hash which makes it hard for data to be tampered with once it is stored on a block.

Transparency

As all users in a blockchain network have access to the same information, it makes sure each user can verify their data promoting trust among users.

Distributed Ledger

The blockchain network makes use of a distributed ledger with each user having a copy of the entire blockchain(sounds cool right?). This feature ensures that a singular attack on the blockchain yields no positive result.

Looking at these few features, it is easy to imagine how various industries make use of the blockchain in their daily activities.

Harnessing Blockchain Technology Across Industries

Here are a few examples of how industries across sectors harness the power of the blockchain:

Supply Chain Management

Blockchain offers instant and immediate responses to any query about the supply chain. This can help you in cases where issues arise, this means, it would give you real-time and updated information whenever you need it. This can be helpful in preventing fraud, and can increase the level of trust you would have for your supplier.

Banking and Finance

In the aspect of banking and finance, blockchain technology easily shines. Through its decentralization feature, users are easily protected against fraud as financial transactions are available to be seen and not controlled by a singular entity. The blockchain also improves the speed and efficiency of transfers, reducing the time needed for transactions to be made be it across countries or states.

Healthcare

One of the key areas in which blockchain improves the level of healthcare is medical records management. The blockchain ensures that a patient’s data across various healthcare providers is centralized allowing access to each provider at any time while maintaining its integrity.

Final Thoughts

Everything discussed shows how the blockchain is utilized in the latest version of the internet(Web3) and how industries across different sectors employ its use in their operations.

And though the blockchain might have its cons, its pros outweigh them, revolutionizing the way we see the world and how things are.
