Bitcoin – What Is It and Why Is It Needed

The Bitcoin system uses Blockchain technology, which means “block” and “chain”. This combination of words speaks for itself and reflects the essence of the system. However, for dummies, it is worth deciphering the essence of the blockchain in more detail. So, this is a chain of blocks containing data regarding transactions. It is somewhat similar to the account book and is stored by each user, and is updated from time to time. It is important that this chain is characterized by continuous action.

It guarantees high reliability and decentralized operation of Bitcoin. However, this feature is not visible to every user, since it is activated exclusively at the time of checking transactions.

The size of one block of transactions in Bitcoin is 1 Mb, while it can include up to several thousand operations. Interestingly, each new block in the chain retains information regarding completed transactions included in it, as well as all past blocks. To synchronize new and previous blocks, you must use special hashed headers. A block can be included in the main network only if all the transactions that are part of it are verified. Assignment of an individual title is carried out on similar conditions. Once the verification is confirmed, the block receives the header and is included in the main network. Starting from this moment, no possible changes can be made to the block in any way.

Experts say that blockchain technology is another step into an easier and safer future. Thanks to this technology, it is possible to store absolutely any information. Such technology is considered to be in demand in places where it is necessary to keep records, synchronize information. Even today, it is used in the implementation of projects of a private and public nature.


The essence of the Bitcoin system and blockchain technology lies in the source code, which is open source. This property ensures the usefulness of the communication node for any user and making changes to the system. Additionally, using the source code of Bitcoin, a huge number of other cryptocurrencies and projects were developed.
