What is Blockchain Technology? How does blockchain work? Advantages and Disadvantages of blockchain, you will find the answers to all these questions at the end of this post.

If you’ve been following banks, investments, or cryptocurrencies for the past ten years, you may be familiar with the blockchain technology behind Bitcoin. If you understand this then there is a good chance.

The name of a blockchain depends on how it works and how it stores data, i.e. the information is packaged into a block.


The function of connecting blocks in a chain so that the storage information in a blockchain is so reliable. Once data is entered into a block, it cannot be changed without changing every subsequent block and it cannot be done without seeing other participants in the network. Blockchain distributes digital information on the Internet but does not allow you to copy or modify it, so Blockchain technology has created the backbone of a new type of Internet. Originally created for the digital currency, Bitcoin, the technology community has now found other uses for the technology.

What is Blockchain Technology?

Blockchain is a distributed distribution ledger technology, where every transaction is digitally signed to ensure its authenticity and integrity and is poised to make a big difference in a wide range of business usage situations.Blockchain at its basic level means only a series of blocks, not the traditional meanings of those words.

History of blockchain

Blockchain technology was first mentioned in a document or white paper published in 2008 by the mysterious creator of Bitcoin founder. It is simply called Satoshi Nakamoto. With the publication of Nakamoto in the opening letters of a man born in Japan on April 5, 1975, speculation about the true identity of this undisputed code still exists.

It is also worth noting that Satoshi Nakamoto did not create every aspect of blockchain from the beginning. In fact, none of the technologies used in the blockchain were particularly new and lasted for many years. However, this happened when blockchain technology was known, used in conjunction with each other, and became a revolutionary sacrifice.

How does blockchain work?


Think of a spreadsheet that has been duplicated thousands of times over a computer network. This network is meant to update this computer program frequently and assumes you have got a basic understanding of blockchain.

The information stored in a blockchain remains as a database – and is constantly being reconciled. It is a method of using the network with obvious benefits. The blockchain database is not stored in a single location, which means that the records it holds are genuinely public and easily verified. There is no centralized version of this information to corrupt a hacker. It hosts millions of computers at once and its data is accessible to anyone on the Internet.

Explain this further,

When it comes to blockchain editing a new transaction or an existing transaction, an algorithm must be implemented to estimate and validate the history of individual blockchain blocks, usually for the many nodes in the blockchain implementation.If there is an agreement that the history and signature of many nodes are valid, a new transaction block will be accepted in the ledger and a new block will be added to the transaction chain. If the majority does not accept additions or modifications to the laser access, it will be rejected and not added to the series. This distributed compromise format allows blockchain to be run as a distributed ledger without the need for something central, and to tell the authority whether the transactions are legal (and more importantly).

Blockchain can be configured to work in many ways, using various mechanisms to gain agreement on transactions and especially to define known participants in chains and exclude all others. The biggest example of the use of blockchain is Bitcoin. This is an anonymous public account that anyone can participate in. Among the small number of known actors, many organizations use controlled blockchain for personal use in blockchain, which is involved in the transaction.

The advantage of blockchain

  • Distributed

The standard database has a centralized structure that revolves around a central point of authority. Once it is corrupted, if the entire system fails on the other hand there is a blockchain distributed structure and no central authority.

  • Secure

Blockchain is made out of digital blocks that contain information on every transaction ever made on the system. Once the port of dark hacked, the system rejects the tampered information and remains secure.

  • Accessible

Allowing different parties to exchange information, ensuring a smooth and fast flow of data.

  • Immutable

Data cannot be changed and a new block is created every time an update occurs.

The disadvantage of a blockchain

  • The technologies are not mature enough
  • The development communities are small, available code snappers don’t work bugs are silent, etc.
  • It is very difficult to comprehend the code.
  • The blockchain concept is complex.
