Everything You Need to Know About Blockchain

What is Blockchain?

A blockchain may be considered a distributed ledger or database accessible to all computers in a network. Blockchain is a digital ledger that stores records of transactions and other information. In the cryptocurrency system, blockchains play a crucial function in maintaining secure and decentralized records of transactions for cryptocurrencies like Bitcoin and Bitcoin. Briansclub provides all types of cryptocurrencies on its website to sell and exchange tokens. A blockchain's main advantage is the security and trustworthiness of the information it stores. It also establishes credibility without calling on an impartial third party.

What is the Function of Blockchain?

The purpose of Blockchain is to permit digital data to be stored and shared without editing. This is why blockchains are the basis for immutable ledgers or records that record transactions that can't be altered, deleted, or destroyed. This is why blockchains are also referred to as distributed ledger technology (DLT). 

Blockchain Decentralization

Imagine a business with a server farm that houses 10,000 computers to manage an account database containing the entire client's account details. The company has an office building which houses all these computers under one roof. It is also in complete control of each computer and the data stored in the databases. However, this is one source of failure. What happens when the electricity in the area goes out? What happens if their Internet connection is interrupted? What happens if it burns to the floor? What happens if a criminal erases all data with one keystroke? In any event, the data will be destroyed or lost.


Due to the decentralization of Bitcoin's blockchain system, all transactions are visible through a personal node which allows anyone to observe transactions happening live. Each node can update its chain version when new blocks are added and confirmed. This means that, if you do so, you can follow Bitcoin wherever it travels.

Exchanges, for instance, were hacked previously, in which the people who held Bitcoin on the exchange were able to lose everything. While the hacker could be private, the Bitcoins they took can be easily tracked. If the Bitcoins taken in any of the hacks were transferred or used in any way, they would be identified.

Is Blockchain Safe?

Blockchain technology provides the decentralization of security, trust, and protection in a variety of ways. In the beginning, the blocks are stored chronologically and linearly. This means they will always be added at an "end" of the Blockchain. It's only possible to change the block's content if most network members agree to make the change. 

Bitcoin Vs. Blockchain

Stuart Haber and W. Scott Stornetta were two researchers who sought to establish an electronic system that would ensure that documents' timestamps were not altered. It wasn't until 20 years later, after the debut of Bitcoin in January 2009, that blockchain technology saw its first application in the real world.

Blockchain, in contrast. Banks

Blockchains are hailed as an innovative force in the finance industry, particularly in banking and payment. But, decentralized banks and blockchains are distinct.

To understand how a bank differs from Blockchain, we'll examine the banking system with Blockchain's implementation in Bitcoin.

The pros and cons of Blockchain

With all its complexity, the potential of Blockchain as a decentralized method of record-keeping is virtual without limitation. From increased privacy for users and increased security to lower processing costs and fewer errors, Blockchain technology could have applications beyond the ones listed in the previous paragraphs. However, there are a few negatives.


  • Accuracy improved by eliminating the involvement of humans in the verification.
  • Cost savings through the elimination of third-party verification
  • Decentralization makes it difficult to interfere with
  • Transactions are safe, private, and efficient.
  • Transparent technology
  • Offers a bank alternative as well as an option to secure the private information of those living in countries with a weak or unstable government


  • The high cost of technology related to mining bitcoin.
  • Transactions per second are low.
  • Use in illegal activities, like the dark web.
  • Regulations vary by country and need to be clarified.
  • Limitations on storage of data. 


  • Blockchain is a shared database that differs from the typical database in how it stores information. Blockchains contain data in blocks which are later linked via cryptography.
  • As new information is received, it is inserted into an entirely new block. When the block is full of data, it is subsequently chained onto the previous block, linking the data in chronological sequence.
  • A variety of types of information can be saved on a blockchain. However, the most widely used use thus is as a ledger to record transactions.
  • In the case of Bitcoin, blockchain technology is utilized in a way that is decentralized, meaning that no one individual or group holds power. Instead, everyone has control.
  • Decentralized blockchains are immutable, meaning that the information entered is irreversible. For Bitcoin, it implies that transactions are permanently stored and accessible to all.
  • Many platforms like briansclub provide the selling and exchanging of coins and currencies with the facility of credit/debit card transactions.
