Bitcoin and BlockChain Technology - Let’s make some money

Hello Ninjas, We are back with an article based on Cryptography i.e Bitcoin and Blockchain technology. Many people are making a massive amount of money through cryptocurrencies nowadays. However, there has been extensive debate regarding using cryptocurrencies for money-making. That debate is majorly based on two essential terms Bitcoin and Blockchain.

Let's move toward the detailings of both Bitcoin and Blockchain.

Bitcoin and Blockchain Technology


A Blockchain is a decentralized, distributed database or ledger implemented in 2000 and developed by Santoshi Nakamoto to store all the records electronically. Because of blockchain technology, the role of cryptocurrency systems, such as Bitcoin, is to maintain a secure and decentralized record of transactions. In simpler words, pieces of data are stored in blocks, and each network node has a replica of the complete database.

It guarantees the security of the data record and generates trust among the users.

Bitcoin and Blockchain technologies are linked together in a certain way.


Blockchain vs Database

Let’s see what are the differences between Blockchain and Database in detail.

Feature Blockchain Database
Type Blockchain is decentralized. The database is centralized.
Security It is fully confidential The database is not fully confidential.
Speed Blockchains are slow Database are fast
Operations It has only insert operation. It has create, read, update, and delete operations.
Store of data Blockchain stores the data in blocks. The database stores the data in tables.

Data in Blockchain

Blocks store some information or data; the first information it will store is relevant information, like for bitcoin, and the relevant information will be the transaction process. The second information that will be stored is hash; now hash can be understood as a unique fingerprint-like in Blockchain, all the data stored in the block will have a unique hash assigned to it. The third information that will be stored in the block will be the prev hash. The prev hash will contain the information of the previous block's hash.

So in this way, all the information or data is secured, updation is easy, and tracking information is easy. 

Working of Blockchain

Blockchain follows a multistep process. Let’s see them with the help of the flowchart.

  • An authorized individual initiates a transaction which is authenticated by the technology.
  • This creates a block which will contain the specific transaction data.
  • The block is sent to all the nodes of the system’s network.
  • All the authorized nodes verify and certify the transaction block.
  • The block is added to the existing blockchain with the help of the hash.
  • The transaction is executed finally and the update is distributed across the network.

Note: All these steps take place in real time.

Working of Blockchain

Pros of Blockchain

Some of the pros of Blockchain are:

  1. It has transparency
  2. Transactions are secured and private
  3. Cost reductions by eliminating the third party
  4. Improved accuracy

Cons of Blockchain

Some of the cons of Blockchain are:

  1. Transactions are low per second
  2. Storage space is limited
  3. Regulation varies by jurisdiction and remains uncertain

Benefits of Blockchains

Here in this section, we will discuss all the benefits Blockchain has.

Reduced Costs

The main benefit of Blockchain has reduced costs because Blockchain eliminates the need for third-party verification, and thus the costs associated with it get reduced.

Greater Security

Once a transaction is recorded in the database, the authenticity of the transaction must be verified by the Blockchain immediately. Thousands of computers on the blockchain rush to confirm whether the details of the recorded transaction are correct or not. So Blockchain provides us with secured transactions.

Efficient transactions

Blockchain works all the time(24 hours in a day, seven days of a week, and 365 days in a year). So transactions can be completed in as little as ten minutes and considered secure after just a few hours.


Most Blockchains are entirely open-source software, which means that anyone and everyone can view the code. This means that there is no real authority on who controls the code of Bitcoin or how it is edited, as it gives authority to review cryptocurrencies.


With Blockchain, you are assured that you will receive accurate and timely data. Your confidential information will not be shared with any random person.

Blockchain's Applications

  • Healthcare
  • Money Transfer
  • Logistics
  • Internet of Things
  • Smart Contracts
  • Voting/ Government

The crypto world is full of jargon which we will untangle in this section. Cryptocurrency, like Bitcoin, Litecoin, etc., is a form of digital money. Behind Bitcoin, cryptocurrency is a blockchain known as the Bitcoin blockchain.


Bitcoins are not stored physically on any platform, and it uses a mathematical algorithm to protect a string of numbers stored in public and a private key.

Working of Bitcoin

Bitcoin works on a ledger called Blockchain. Both Bitcoin and Blockchain are interrelated to each other. Bitcoin is a peer-to-peer network. Users can exchange Bitcoin with others without the need of any middlemen to conduct and confirm the transactions via the network. 

Users can join this network directly and gain access to the blockchain, which contains a record of all prior Bitcoin transactions. 

Pros of Bitcoin

Some of the pros of Bitcoin are:

  • Reduced possibility of identity theft
  • Security
  • Greater Liquidity 
  • Identity
  • Transparency

Cons of Bitcoin

Some of the cons of Bitcoin are:

  • Limited Use
  • Scams and Frauds
  • Volatility
  • Irreversible

Bitcoin's Applications

Applications of Bitcoin are as follows:

  • It provides a secure way for transactions.
  • It can be used to gamble on online sites
  • It can be used to buy goods and services
  • It can be used to do online shopping
  • International payments can be made easily and cheaply

Blockchain Vs. Bitcoin

Let’s see what are the differences between Blockchain and Bitcoin in detail.




Type Blockchain is a decentralised data structure or ledger. Bitcoin is a cryptocurrency.
Mechanism It is a transparent mechanism. Bitcoins operate on anonymity.
Use It is more extensive in use. Bitcoin is restricted to exchange in digital currencies.
Scope It is more open to new changes, and hence it is chosen by many companies. The scope of Bitcoin is limited.
Flexibility  Blockchain technology can adapt to new technologies.  Bitcoin focuses on lowering the cost of influencers.
Aim Its main aim is to provide secure, low- cost transactions. Its main aim is to simplify and increase the speed of transactions.
Application Blockchain is generally used because it may transmit various items, including money and rights, to real estate. Bitcoin's application is restricted in comparison to currency transfers.

Future of Bitcoin and Blockchain 

Blockchain continues to dominate our internet spaces. It is essential to exercise caution when dealing with cryptocurrencies. For example, use trustworthy service providers if you are pursuing crypto gambling. Often online casino websites use third-party service providers to convert your bitcoin deposits into local digital currency.

Bitcoin and blockchain technology remain mostly under or unregulated worldwide due to innate complex structures. Therefore be careful while using bitcoins in any online transaction.

Frequently Asked Questions

What is Blockchain?

A blockchain is an encrypted, distributed ledger or database which uses public and private keys to maintain a sort of virtual security while doing the transaction process.

What is Bitcoin?

Bitcoin is one of the most used and earliest cryptocurrencies to use blockchain technology to provide a secure way to transact securely online.

Who developed Bitcoin?

Bitcoin was invented by an unknown person Satoshi Nakamoto in the year 2008.

What is the role of blocks in Blockchain?

Blockchains consist of records with data or information stored in the blocks. These blocks are connected or linked to other blocks and form a blockchain.

Name some popular types of cryptocurrencies.

Some popular cryptocurrencies are Ethereum, Bitcoin, Tether, USD Coin, XRP, etc.
