What is Blockchain?

The blockchain infrastructure is a peer-to-peer network that contains information about transactions (also called blocks) that are publicly available in many documents, also called “chains.” This type of storage is often referred to as a “digital book”. Although most people associate blockchain technology with cryptocurrencies such as Bitcoin, it provides security in other ways. Since you are creating a record, you have coined the term “string”. The fact that the above block cannot be changed makes it very safe. 

Since the blockchain is based on consensus, no one can manipulate data. You don’t need a trusted third party to monitor or verify blockchain transactions. With the introduction of blockchain technology, with the demand for professional talents, the demand for blockchain is also increasing. From a bird’s eye view, blockchain developers specialize in the creation and application of blockchain-based architectures and solutions. The estimated annual income of blockchain developers is $469,000.





What does role blockchain can play?

The rolr or impact of blockchain technology on society is very important. These include:

a) Bitcoin:

Bitcoin benefits many people through the financial services (such as encrypted wallets). This is the main application of this technology and the reason for its development. Provide small loans and small payments to people with poor financial status.

b) IoT:

The Internet of Things (IoT) has introduced many smart devices that can transmit data over the Internet without manual intervention. Garbage collection, transportation and traffic management services. Therefore, in the world of IoT, you can create smart devices. Sign a contract and allow smart objects to perform operations

c) Healthcare Industry:

In the healthcare business, In healthcare, blockchain technology can be used as a safe channel to ensure patient privacy. The health organization will use technology to develop unique databases and share information only with officially verified personnel.

d) Peer-to-peer Network:

For companies or applications like Uber, blockchain technology can create a decentralized peer-to-peer network where users can pay fees and parking fees.


The principle of TRUST, especially in international transactions. The next major impact, the emergence of cryptocurrencies, has fundamentally changed TRUST relationships. Many organizations find themselves in an area of ​​insufficient funding and high levels of corruption. In this case, blockchain brings huge benefits by helping participants and organizations.




 What exactly is blockchain technology and how does it function?

Many companies around the world have been using Blockchain technologies in recent years. So what is Blockchain technology and how does it work? Is this a major update or a moderate update? Because the development of blockchain technology is still in progress. In the early stages of development, perhaps in the future, we need to discover the secrets of this technology, which is a combination of three common technologies. Peer-to-peer network with shared registers.

  • Encryption key
  • Peer-to-peer network with shared ledger
  • Computer environment for storing network transactions and records


1: Encryption key

The encryption key used to store network transactions and logs. Encryption is done by public key and private key. These two keys are unique to everyone and are used to create a secure digital identity. The logo is called a “digital signature” in the crypto community and is used to authorize and monitor transactions.

2: Peer-to-peer network with shared ledger

A peer-to-peer network with a combination of universal ledgers and digital signatures. Many officials use digital signatures to reach consensus. Information about purchases and other transactions between the two parts of the network.

3: Computer environment for storing network transactions and records

When they approve a contract, it is checked mathematically, resulting in a successful encrypted transaction between the two networked parties. In short, blockchain users use encryption keys to conduct various forms of digital transactions on a pair.




Blockchain Advantages:

  Blockchain is a new platform that provides many advantages in an increasingly digital world:

1: Automation

Smart contracts also simplify transactions, improve reliability, and further speed up the process. The smart contract that meets the pre-defined conditions of automatic activation eliminates the need for manual intervention, and no longer needs to rely on a third party to enforce contract conditions and submit compliant.

2: Hunt down immediately

Check the blockchain at every stage of the asset journey. Pay close attention to the source of the product and whether consumers are concerned about harm to people or the environment related to the product. Provide evidence of your department or industry. Forgery and fraud are possible. Blockchain allows direct exchange of raw data to consumers. Tracking details can also reveal interruptions in the supply chain, for example:  When there are products waiting to be shipped on the loading dock.

3: Highly Secured

Your knowledge is sensitive and important, and the blockchain can fundamentally change the way it perceives. Blockchain aims to prevent theft and illegal activities by creating an immutable ledger encrypted from beginning to end. Blockchain can solve data protection problems by anonymizing personal data and restricting access rights. Since the data is not stored on a central drive, but on a computer network, it is difficult for hackers to access it. Free transactions, if there is no unique digital signature, it will be difficult for other users to destroy or change someone’s data.

4: Increase your efficiency and quickness

Traditional paper-based systems are time-consuming, prone to human error, and usually require third-party intervention. By using blockchain to simplify these operations, transactions can be executed faster and more efficiently. Documents and transaction data can be stored in the blockchain, making paper transactions redundant. Since there is no need to consolidate multiple ledgers, processing and arbitration can be completed faster.

5: Higher transparency

Without the blockchain, every company must maintain its own server. Transactions and data are recorded in the same way in different locations because the blockchain uses a distributed ledger. All authorized network members can see the same information at the same time, thus ensuring full accountability. The input is unchanged. In this way, participants can view the entire transaction history, effectively eliminating the possibility of theft.

6: Decentralized System

 Generally, transactions require approval from regulatory agencies (such as governments or banks). However, with the use of blockchain, transactions will be completed in accordance with the user’s consent, thus making transactions simpler, cleaner, and faster.


Disadvantages of Blockchain:


The climate is changed by blockchain technology. However, in order to understand what to do, we must first understand the shortcomings. This section covers all the following points:

1: Private Keys: Users Are Their Own Bank

The user is their own bank. In order to decentralize the blockchain, individuals must be able to act as their own bank. However, this leads to another problem. The private key is used to access user attributes or information contained in the blockchain. They are created during the wallet development process, and it is the user’s responsibility to track them to ensure that they are not shared with anyone. If they do not obey, the wallet will be damaged. However, if you lose the key, you will not be able to access the wallet. One of the disadvantages of blockchain is its reliance on consumers.

2:  Immutable Data

Another problem is that data cannot be deleted before everyone has the right to privacy. However, if the same user uses a decentralized network based on blockchain technology, they cannot delete the footprint of the device until they no longer want to be there. In other words, you must delete traces without compromising your privacy.

3: Blockchain can sometimes be invalid:

Of course, there must be a simpler way to do this, because the node must repeat the data after changing the data. Moreover, as more transmissions and nodes are added to the blockchain, its size will increase. When it started to expand, the entire network was left behind. This does not apply to commercial blockchains where fast and stable networks are important. There are currently several blockchain applications available. If you choose the most common way, Blockchain infrastructure, you will find many errors in the mechanism.

4: High Cost with difficult to deploy

You also need to consider the service costs associated with the solution. The cost of enterprise blockchain projects will even exceed one million dollars. Wait longer to join the blockchain train. The inherent cost of implementing blockchain technology is huge. Hire developers to supervise teams that excel in all aspects of blockchain technology, if you need to pay for the licensing fees of blockchain solutions, etc. Everything has a price

5: Skilled knowledge

 The need to hire many experts in the blockchain industry causes problems, so it is considered one of the shortcomings of the blockchain. It is difficult to implement and manage blockchain projects. This process requires a detailed understanding of the market. In addition, they must train employees to use blockchain. The management team is familiar with the complexity and results of blockchain-based companies. You will be able to better understand their needs and help them transform. Your business process uses blockchain.
