What Is Blockchain Technology?: If you are interested in the future of money, you need to learn about blockchain. Blockchain is a digital ledger that is growing in popularity as a way to track intellectual property (IP) ownership.

Unlike traditional, centralized databases, the blockchain is decentralized, meaning it is not controlled by a single entity. This makes it a powerful tool for tracking the flow of goods and money, as well as ensuring intellectual property protection.

What is Blockchain Technology?

Blockchain technology is an advanced data method that enables the transparent exchange of information on a corporate network. A blockchain database stores data in blocks that are linked together in a chain. The data is sequential as you cannot delete or alter the string without network approval. This allows you to create an immutable or immutable ledger using blockchain technology to track orders, payments, accounts, and other transactions. The system has built-in procedures that prevent unauthorized transactions and provide consistency in the collective view of transactions.

Why is Blockchain Technology Important?

Traditional database technology poses several challenges to recording financial transactions. Think of real estate sales, for example. Once the money is exchanged, ownership of the property passes to the buyer. Both buyers and sellers can individually record transactions, but neither source can be trusted. The seller can easily claim that he did not receive the money even though he did receive it, and the buyer can claim at the same time that he paid the money or not.

To avoid potential legal issues, a trusted third party should monitor and verify the transaction. The presence of this central authority not only disrupts work but also creates a central vulnerability. If the central database is compromised, both parties can suffer.

Blockchain mitigates these issues by creating a decentralized, tamper-proof system for recording transactions. In real estate transactions, the blockchain creates a single ledger for buyers and sellers. All transactions must be approved by both parties and updated automatically in real-time on both ledgers. Any corruption in history will destroy the whole book. The properties of blockchain technology have led to its use in various fields, including the creation of digital currencies like Bitcoin.

How do Different Industries Use Blockchain Technology?

Blockchain is an emerging technology that is being used in new ways by various industries. In the following sections, we describe several use cases in different industries:


Energy companies are using blockchain technology to create peer-to-peer energy trading platforms and streamline access to renewable energy. For example, consider this utility:

  • Blockchain-based energy companies have created a trading platform to sell electricity between people. Homeowners with solar panels use this platform to sell their excess solar power to neighbors. The process is automated: Smart meters perform transactions and the blockchain records them.
  • Blockchain-based crowdfunding programs allow users to fund and own solar panels in communities that don’t have access to them. Sponsors can receive rent from the communities once the solar panels are installed.


Traditional financial systems like banks and exchanges use blockchain services to manage online payments, accounts, and market trading. For example, Singapore Exchange Limited, an investment management company that provides financial trading services across Asia, is using blockchain technology to create a more efficient payment account for banks. Blockchain adoption has solved several challenges, including batch processing and manual reconciliation of thousands of financial transactions.

Media and Entertainment

Media and entertainment companies use blockchain systems to manage copyright data. Enforcement of copyright is critical to properly remunerating artists. Multiple transactions are required to record the sale or transfer of copyrighted material. Sony Music Entertainment Japan uses blockchain services to make digital rights management more efficient.

Retail companies use blockchain to track the flow of goods between suppliers and buyers. For example, Amazon sellers have filed a patent for a distributed ledger technology system that uses blockchain technology to ensure that all goods sold on the platform are authentic. Amazon sellers can map their global supply chain by allowing stakeholders such as manufacturers, couriers, retailers, end users, and secondary users to add events to the log after registering with a certificate authority.

What are the Characteristics of Blockchain Technology?

Blockchain technology has the following main characteristics:


Decentralization in the blockchain is the transfer of control and decision-making from a central organization (individual, organization, or group) to a distributed network. Standardized blockchain networks use transparency to reduce the need for trust between participants. The networks also prevent participants from exercising authority over one another or controlling them in a way that affects network performance.


Immutable means something that cannot be altered or altered. No participant can interrupt the transaction once someone has recorded it in the common ledger. If the transaction record contains an error, you must add a new transaction to reverse the error. Both transactions are then visible to the network.


A blockchain system establishes rules for allowing participants to record transactions. You can only record a new transaction if the majority of participants in the network agree.

What are the key Components of Blockchain Technology?

The blockchain architecture consists of the following main components:

A Distributed Ledger

A distributed ledger is a shared database on a blockchain network that stores transactions, much like a shared file that anyone in a group can edit. In most shared text editors, anyone with editing rights can delete an entire file. With distributed ledger technology, however, strict rules apply to who can process what. You cannot delete an entry once it has been recorded.

Smart Contracts

Businesses use smart contracts to manage their business contracts without the need for a third party. These are programs stored in a blockchain system that is automatically activated when specified conditions are met. They use IF checks so transactions can be completed safely. For example, a shipping company can set up a smart contract that automatically makes payment once the goods have arrived at the port.

Public key Cryptography

Public-key cryptography is a security feature used to uniquely identify participants in a blockchain network. This process generates two key sets for network members. A single key is a public key shared by everyone on the network. Another private key is unique to all members. The private and public keys work together to unlock the data in the ledger.

For example, John and Jill are two members of the network. John records the transaction encrypted with his private key. Jill can remove it with her public key. In this way, Jill is convinced that John carried out the transaction. Jill’s public key would not work if John’s private key was tampered with.

How does Blockchain Technology Work?

Although the underlying mechanisms of the blockchain are complex, we provide a brief overview of the following steps. Blockchain software can automate most of these steps:

Record the Transaction

Blockchain activity shows the movement of physical or digital assets from one party to another on the blockchain network. It is recorded as a block of data and can contain information such as:

  • Who was involved in the trade?
  • What happened during the transaction?
  • When did the transaction take place?
  • Where did the transaction take place?
  • Why did this happen?
  • How much material has changed?
  • How many requirements are met at the time of purchase?

Gain Consensus

Most participants in a distributed blockchain network must agree that recorded transactions are valid. Depending on the type of network, the negotiation rules can vary but are usually established at the beginning of the network

Link the Blocks

Once participants have reached a consensus, transactions are recorded on the blockchain in blocks the size of ledger pages. Along with the transaction, a cryptographic hash is also added to the new block. The hash acts as a chain that connects the blocks. When the content of a block is changed, intentionally or unintentionally, the hash value changes, providing a way to detect data tampering.

So blocks and chains are securely connected and cannot be edited. Each additional block reinforces the validation of the previous block and therefore of the entire blockchain. It’s like piling blocks of wood into a tower. You can only place blocks on it, and if you remove a block in the middle of the tower, the whole tower will break.

Share the Ledger

The system distributes an updated copy of the central ledger to all participants.

What are the types of Blockchain Technology?

There are four main types of decentralized or distributed networks in the blockchain:

Public Blockchain Networks

Public blockchains are permissionless and allow anyone to join them. All blockchain members have equal rights to read, edit and review the blockchain. People mainly use public blockchains to exchange and mine cryptocurrencies like Bitcoin, Ethereum, and Litecoin.

Private Blockchain Networks

A single organization controls private blockchains, also called managed blockchains. The authority determines who can become a member and what rights they have in the network. Private blockchains are only partially decentralized as they have access restrictions. Ripple, a corporate digital currency exchange network, is an example of a private blockchain.

Hybrid Blockchain Networks

Hybrid blockchains combine elements of private and public networks. In addition to a public system, companies can also set up private, license-based systems. In this way, they control access to specific data stored on the blockchain while keeping all information public. They use smart contracts to allow the public to verify that a private transaction has been completed. For example, hybrid blockchains can provide public access to digital currencies while keeping bank accounts private.

Consortium Blockchain Networks

A group of organizations operates consortium blockchain networks. Pre-selected organizations share responsibility for maintaining the blockchain and determining data access rights. Industries where multiple organizations share common goals and benefit from a shared responsibility often opt for consortia blockchain networks. For example, the Global Shipping Business Network Consortium is a non-profit blockchain organization that aims to digitize the shipping industry and improve collaboration between maritime industry operators.

What Is the Advantage Blockchain Technology Offers?

Blockchain technology offers many advantages for managing asset transactions. We list some of them in the following paragraphs:

Advanced Security

Blockchain systems offer the high level of security and trust that modern digital transactions require. There is always a fear that someone will cheat the software to make fake money. But blockchain leverages the three principles of cryptography, decentralization, and consensus to create an underlying software system that is highly secure and nearly impossible to tamper with. There is no single point of failure and a single user cannot change transaction records.

Improved Efficiency

Business-to-business transactions can take a long time and create operational problems, especially when third-party compliance and regulatory bodies are involved. Transparency and smart contracts on the blockchain make such business transactions faster and more efficient.

Faster Auditing  in Blockchain Technology

Businesses must be able to securely generate, exchange, archive, and legibly replicate e-commerce. Blockchain records are chronologically immutable, which means all records are always edited promptly. Data visibility greatly speeds up research processing.
