A blockchain is defined as a data structure that maintains a continuously growing list of data records and transactions.To simplify, a blockchain is a public ledger of all Bitcoin transactions that have been executed. It makes it possible to share the list of records and transactions among a distributed network of computers.

Blockchain utilizes cryptography to enable each participant on the network to manipulate the ledger in a safe manner without the necessity for the central authority.The blockchain is constantly growing due to the fact that completed blocks are added it with a brand new set of recordings.

The completed blocks are added to the blockchain in a chronological, linear order. Every node gets a copy of the blockchain which is automatically downloaded after joining the Bitcoin network.Node is a computer connected to the Bitcoin network using a client that has the task to validate and relay connections.

The blockchain contains information about the balances and addresses straight from the genesis block.When a block of data is recorded on the blockchain ledger, it is very difficult to remove it or make some modifications. Let’s say someone wants to add something to the data on the blockchain ledger, then all participants in the network run algorithms to evaluate and verify the proposed transaction.

If most nodes agree that the transaction looks valid, then it’s approved and a new block is added to the chain.


The blockchain technology has numerous benefits, including the following:

  • Empowered users – One of the greatest advantages of blockchain is that users are in complete control of the process, information, and all the transactions.
  • Fast transactions – Interbank transactions can last for up to a few days, especially when they’re made out of working hours. On the other hand, blockchain transactions speed up the entire process to a matter of minutes.
  • High-quality data – Blockchain data is consistent, complete, timely, widely available, and accurate.
  • Honesty and fairness – As mentioned above, blockchain data is difficult to change and modify and one needs approval from all parties on the network. This minimizes chances of wrongdoings because blockchain technology is transparent and incorruptible.
  • Lower transactions costs – Blockchain doesn’t require third-party involvement, which is why transaction fees are much lower.
  • No third-party inter-mediation – Two parties are able to make an exchange without the oversight of some third-party intermediation, thus eliminating or significantly reducing counter party risk.
  • Reliability and longevity – Thanks to decentralized networks, blockchain doesn’t have a central point of failure and it’s able to withstand malicious attacks.
  • Simplicity – Since all transactions are added to a single public ledger, blockchain reduces the clutter and complications associated with multiple ledgers.

Blockchain technology has been around for a while. In 2008, a person or a group of people going under the name of satoshi nakamoto published a paper wherein they described:

Bitcoin and how it could be utilized to, digitally, send payments between two parties without the middleman. While some assumed that bitcoin and blockchain technology would be forgotten just like many other fast-emerging trends, the reality is much different.

In fact, blockchain technology is gradually changing the corporate world and the business we do today, one block at a time. Until now, a centralized company was the most effective way to create a network aimed to solve a large need. Thanks to the blockchain technology, we no longer need central companies to act as the middleman.This and other business models of the future are software protocols developed, governed, and owned by the communities they support.

The blockchain technology doesn’t only benefit banks or big companies, but smaller businesses at the same time. If banks and other financial institutions are able to accelerate transactions and eliminate costs out of the system, that would lead to cheaper and more efficient services.

The implications of blockchain technology can spread to various industries including media or telecommunication. Let’s take a newspaper website as an example, instead of charging subscribers by month, they can charge per page or per article.

For hospitality and travel, a shared distributed ledger can simplify the settlement process. Moreover, blockchain-secured health records could make it easier for patients to share their records with healthcare providers.

Basically, blockchain can change the business we do in many ways. Below, you can see a few examples.


As mentioned throughout the article, the greatest advantage of blockchain is cutting the middleman out of the picture. So, your business can greatly benefit from exchanges performed with this technology.
With blockchain, there’s no need to worry about clearinghouses and currency exchanges. Plus, it allows you to complete the transaction with clients or business partners anywhere in the world, without paying huge transfer fees.

In fact, the overall cost of using blockchain is almost insignificant if you compare it to exchange fees or payment processing fees.


The area of smart contracts is, probably, one of the most distinctive features of the blockchain. This technology helps ensure that both sides of a contract are fulfilled. Thanks to this useful element of the blockchain, you can be sure that your business dealings aren’t jeopardized.

Intellectual property

The implications of blockchain go beyond financial transactions. The internet makes it easier for you to share unique ideas, innovations, and creations, etc. But at the same time, it also makes it easy for other people to just steal it.

Blockchain helps you prove an ownership of some intellectual property and ensures that you are adequately credited. As a result, other people won’t profit from your creativity. This has a positive impact on the business world today because it will prevent the major problem of stealing one’s intellectual property.

Cryptographic signatures

Blockchain technology allows the use of cryptographic signatures for both sending and receiving payments. It can be, also, used to manage shift changes and many other business-related transactions.

Thanks to cryptographic signatures, there’s no printing, signing, and faxing papers back and forth all the time.
Promotions and coupons.

You can use blockchain to keep track of promotions and coupons that you’re running. An important component of this technology is that the information can’t be duplicated and reused.

With the help of blockchain, you can authenticate coupons and promo codes (if you’re concerned about them) to make sure your customers are using them. This is a great way to keep track of limited offers.

Bottom line

The blockchain is the technology behind Bitcoin and it’s dubbed as the business model of the future. The technology allows all parties to send and receive payments in a matter of minutes without paying outrageous fees.

Despite important benefits of blockchain in finances and business dealings, it has many other purposes such as protection of the intellectual property, and so on.

With blockchain technology, the processes that used to be time-consuming and frustrating are completed fast and with maximum safety.
