What is BlockChain? Defination, Advantages and Disadvantages, Opportunities and How does it works ?

Where can I find an explanation of blockchain in simple terms?

Changing, hacking, or cheating the blockchain is difficult or impossible. A blockchain is a digital database of transactions replicated and distributed across the full network of computers on the blockchain.
A Google Doc can be used as a basic analogy to help explain the workings of the blockchain. We distribute it rather than copying or transferring a document when we share it with others. As a result, the document is distributed in a decentralized manner, allowing everyone to see it simultaneously. In real-time, all document changes are recorded and transparent to all parties involved.

How Does the Blockchain Work?

Businesses worldwide have been adopting Blockchain technology in recent years, as you may have observed. But how does blockchain technology work? So, what’s the big deal? Is this just a supplement or something more significant?

To begin demystifying blockchain, let’s take a look at some of the most recent developments in this technology. Three key technologies combine to form the foundation of the blockchain:
• Keys to a cryptosystem
• Peer-to-peer network with a shared ledger
• To store the transactions and records of the network in the form of computing

Both the private and the public keys of cryptography are essential. The use of these keys aids in completing successful transactions involving two parties. Each person has two keys, which they use to generate a secure digital identity reference. The most significant component of Blockchain technology is the secure identity. The term “digital signature” is used to describe this identification in the cryptocurrency realm, where it is used to authorize and monitor transactions.

The peer-to-peer network and digital signatures have been integrated; many people who act as authorities utilize the digital signature to agree on transactions and other matters. When they approve a deal, a mathematical verification certifies it, resulting in a successful, secure transaction between the two network-connected parties. So, in summary, Blockchain users use cryptography keys to accomplish various digital exchanges through the peer-to-peer network.

What are the Benefits and Drawbacks of Blockchain Technology?


Blockchain technology is gaining traction as the world moves ever faster toward digital transactions. In addition, the system is highly secure.
As a result, it is difficult for other users to corrupt or change an individual’s data unless they have a precise digital signature. The system is not centralized. Therefore, conventional transactions require the consent of regulatory bodies like a government or bank; however, with blockchain, transactions are done with the mutual consensus of users, which results in smoother, safer, and faster transactions. With regards to automation, When the trigger conditions are met, it can initiate a series of automated actions, events, and payments.


There have been issues with private keys in the blockchain and cryptography community. To put it briefly:
Block chains have a major drawback for users losing their private keys. Another drawback is that the number of transactions per node is constrained. Because of this, several transactions and other procedures can take several hours to complete. Another notable drawback of blockchain is the difficulty in editing or adding to previously recorded data.

What are the Business Opportunities of Blockchain?

• The financial services sector

The financial businesses are aware that blockchain has its safety system capable of tracking the numerous multi-million dollar transactions every day. Since the records in such a system are trustworthy, there is less data loss. There will be a modest fee for each transaction, but the money or information will be sent immediately. There will be more and more changes in this area in the future, making the system more convenient, inexpensive, and fast to use.

• Second is the health care sector

There needs to be a major overhaul in the interchange and storage of medical records since the current system is extremely out-of-date. Such modifications and the latest developments in health care have already taken place in many nations, as the new system is easier to use and safer.
Patients and doctors can access medical records and other paperwork stored on the blockchain securely and confidentially. Data security and the speed and accuracy of patient diagnosis and other medical documentation can be greatly improved by this method.

• The financial sector

Blockchain technology has a lot to offer when it comes to providing legal services. Most of the ills of the current legal system will be alleviated. Additionally, it will make it possible to store and verify documentation data securely. False data can be corrected and deleted throughout the trial, for example. It should come as no surprise that the most recent advancements in this industry will be highly sought after.

• Cryptocurrency Exchanges

If digital money is our ticket to the future, then a blockchain will safeguard its transfer and place it in our possession. Because of the rising popularity of crypto currencies, the demand for bitcoin exchange platforms has grown.

The scalability of currencies is a major issue with modern cryptocurrency exchange systems, particularly when many computations and capacities are required for these procedures.
Time and money have been wasted as a result of this issue.
Work in the bitcoin industry could be transformed by breakthroughs in blockchain technology for business. The inventors of Zen Protocol have created an alternative to all cryptocurrency exchange platforms, and they’ve been able to address some of the most pressing issues in only the cryptocurrency field.

In addition to their tendency for corruption, government systems are considered sluggish and inefficient. 5. Implementing blockchain-based solutions can greatly reduce bureaucracy boost the overall security of government procedures, their efficiency, transparency, and performance of various government functions.

In the United States, Blockchain Technologies was proposed in 2015 to replace the current voting system with a blockchain-based one. In the United States, Blockchain Technologies is a well-known blockchain-based company. The new voting mechanism did an excellent job and was well accepted.

• Inherent social advantages

It is also necessary to make major reforms to the public goods system, which is also hampered by bureaucracy and delays. When evaluating, validating, and disbursing various unemployment benefits, blockchain technology can be a huge asset. Additionally, the blockchain has a significant chance of bringing about a universal basic income. Block-link-based technologies are being developed to implement a universal and stable basic income in many initiatives.

• The video business

Video is expected to account for 82% of all Internet traffic by 2021, and the blockchain can play an important role in transforming, enhancing, and decentralizing the entire video infrastructure. Decentralization of video infrastructure is becoming increasingly important as video traffic grows at its current rate. Reduced video traffic costs are expected as video coding, storage, and distribution become more decentralized and distributed via Internet resources.

• Eighth is the education sector

Students’ coursework can be stored on a blockchain. It will be impossible for anyone to re-use someone else’s work, even if submitted 5 years ago. This also ensures the integrity of grades, as they cannot be modified or erased on a blockchain.

• Internet security

However, even though a block register is open to the public, all data is double-checked and encrypted using various cryptographic techniques. As a result, data security and protection are ensured against a wide range of hacks, incorrect modifications, and unauthorized alterations.

Hence, Hacking and the appearance of erroneous data in this field are occasionally possible with immature and unproven programs, even though this is a well-established area of expertise. The speed at which infrastructures and the cyber security system as a whole grow will have a significant impact on how frequent attacks emerge in the future. This makes it easier for consumers to keep their data private and only share it with a select group of people.
