Short and Long Paragraphs on Blockchain in English

Paragraph 1-100 words

It is evident that people keep the record of every transaction in the record register for reference. This is the way of maintaining records in a manual way. Blockchain is the technology that maintains the transaction records electronically. Therefore, Blockchain can be defined as the collection of records or data on the computer in form of blocks. The records are maintained with full security and are decentralized.

Many of us are not aware of Blockchain but have knowledge about Bitcoin. Blockchain is a technology that has came into existence with the advent of Bitcoin in the world. This technology also has a close connection with the banking and trading sectors.


Paragraph 2-120 words

We all have observed that a shopkeeper or small organization always keeps a record of every money transaction in a record register. They keep the record of money invested, profit, expenditure, etc. This is termed the ledger record that refers to the book containing financial records.

In the same way, Blockchain is the digital book of financial records. Blockchain refers to the set of data and information that is store online on computer systems. The data is stored in form of blocks. Every block has a certain space for the storage of data of the transaction records. The different blocks containing the data are interconnected with each other in the sequence of their formation. This data is decentralized that means that it can be accessed by different users at a time.


Paragraph 3-150 words

Blockchain can be stated as the online record book that is shared among all the users. This technology is utilized for recording, storing, and sharing data or information publicly. There is transparency in blocks containing the information and they are highly secured. Blockchain technology was instituted in the year 2008. The credit for inventing this technology goes to Satoshi Nakamoto. He invented this digital record book or ledger to provide aid in transactions of crypto currency Bitcoin.

The initial name given by Satoshi Nakamoto to this technology was Block and chain written as separate words. Later in the year 2016, these two separate words were combined and called Blockchain. Blockchain does not give permission of editing any data or information in the blocks. This can only happen if there is the consent of every user. The change is considered rejected if major users are dissatisfied with the change.


Paragraph 4- 200 words

The different digital blocks containing important sets of data linked together in a sequential format is known as Blockchain. The data stored in the different blocks of the chain is encrypted and is shared with every user of the technology. Blockchain data and records are not managed by any single user but can be assessed by every user who is a part of this network.

Storage of Data in Blocks with High Security

Every bock in forming the Blockchain contains a set of information or relevant data obtained from different types of transactions or use. There are some more important things recorded in the block along with the storage of sets of data and information in the block. Every time when the data or information is recorded in the block an encrypted hash is created that is unique to that particular data. This has is composed of a string of numbers and letters.

Addition of Hash of Previous Block

A hash of the previous block is also stored in the new forming block. It helps in tracking data easily. The attempt of trying to change or modify the data in the block will result in the creation of a new hash. This will bring change to the hash in all blocks and thus the change in the data setting can be easily viewed by the users of this network. Thus it is a secure technology with no possibility of doing any nuisance of fraud by changing the data in the blocks with the pre-equipped data.

Paragraph 5- 250 words

Blockchain is a wonderful and important technology. It plays a major role in the sphere of crypto currencies.  It stores the transaction details of these digital currencies in the blocks. Every data and information is stored with full security with no chances of doing misuse or change in the data. The copies of every data in the blocks are shared on computers of every user in this network. Blockchain technology will soon become popular and prevalent in different industries, banking, environmental, corporate, and trading sectors in the world.

The Advent of Blockchain Technology

The concept of this technology came into existence for the first time in the year 1991. The scientists Stuart Haber and W. Scott Stornetta working on this concept but were not successful. Further, they tried to make the concept successful with different methods but did not gain success.  Satoshi Nakamoto is known for inventing Blockchain technology in reality in the year 2008.

It is still not clarified that Satoshi Nakamoto is a single person or a group of people. He was the inventor of the first crypto currency called Bitcoin by utilizing the concept of Blockchain technology in the year 2009. He was able to bring a successful application of Blockchain technology. Slowly and gradually the Blockchain technology became popular and attained maximum attention in the world.

Blockchain Technology is the Dire need in Future

Blockchain technology is becoming popular and such type of secure technology is the dire need in the future. This is a decentralized technology and thus every user can know the change that is made in the stored information of different use. This brings transparency and trust among the users in using this technology.

Earlier when the records were maintained on paper or manually there were more chances of misusing or changing the recorded data. There are no chances of corruption and fraud because of high security in Blockchain technology. Thus, the use of this technology will be benefitting in different spheres in society.
