Understanding the Synergy Between Blockchain and Cryptocurrency


Blockchain technology is characterized by its decentralized and distributed ledger, which functions as a permanent repository for documenting the ownership of digital assets. Upon storage on the blockchain, data becomes immutable, rendering this technology a transformative force in the domains of payments and cybersecurity.

While blockchains have garnered acknowledgement for their fundamental role in cryptocurrency systems, where they uphold secure and decentralized transaction records, their applications transcend beyond the realm of cryptocurrencies.

A brief history of blockchain:

One of the most significant game-changing evolutions of the 21st century, blockchain technology has had a massive impact on almost every industry today. Even though blockchain gained popularity just a few years ago, its history dates back to the 1990s.

In the year 1991, two scientists, Stuart Haber and W. Scott Stornetta, published their work in cryptography. Their work included a chain of blocks secured using cryptography, so the content and its date couldn’t be tampered with. This system later became known as blockchain technology, referring to the chain of blocks where each block stored vital information.

In 2004, Hal Finney, a computer scientist and cryptography expert, developed a system known as RPoW (Reusable Proof of Work). The system creates a transferrable RSA-signed token by receiving a non-exchangeable (or non-fungible) hash of cash based on a proof-of-work (PoW) token.

Above all, the protocol solved the double-spending problem. Therefore, keep the ownership of RSA tokens registered on the trusted server. Where other nodes can verify and keep the documents integrated.

Then, in late 2008, a whitepaper came up named “Bitcoin: Peer-to-Peer E-cash System” by anonymous Satoshi Nakamoto. He used a hash cash PoW (Proof-of-Work) algorithm with software-based computing functions. Moreover, bitcoin introduced the concept of mining coins. It also ensures verifying the transactions among the decentralized nodes in the network.

Bitcoins are mined for a reward using the PoW algorithm by individual miners. Further, it is verified by the other decentralized nodes in the chain network.

On January 3, 2009,  the first bitcoin block was mined by Satoshi Nakamoto with a reward of 50 bitcoins. On  January 12, 2009, the first transaction of 10 bitcoins from Satoshi to Hal Finny happened.

Eventually, on October 31, 2009, the Bitcoin exchange marketplace launched publicly to trade bitcoins for actual money.

Since 2009, the value of Bitcoin has aggressively grown. By 2012, Bitcoin had reached $250 in value.

Currently, more than 18 million bitcoins have already been mined. Moreover, depending on the present computation resources and rate of mining, by the year 2140, all bitcoins will be mined.

However, the person or community behind this popular discovery is still unknown. The figure of Satoshi Nakamoto disappeared and passed the wisdom of their knowledge to the generation of computer scientists and developers.

Ever since then, we have been hearing and reading about the invention of new blockchain-based applications worldwide.

Why is blockchain so popular?

1. Comprehensive Security: Blockchain technology ensures security as it is impervious to hacking. The data is shared among network members, rendering it invulnerable to unauthorized access or breaches.

Because of its guaranteed security and the trust it has shown over time, everyone embraces it. Blockchain uses the three principles of cryptography, decentralization, and consensus to create a highly secure underlying software system that is nearly impossible to tamper with. There is no single point of failure, and a single user cannot change the transaction records.


2. Cryptography: Blockchain keeps transactions safe by using special codes that scramble the information, making it hard to change any data.

3. Consensus protocols: These rules help everyone on the blockchain agree on what’s true. The network nodes check and approve all transactions before adding them to the network.

4. Decentralized network: Blockchain spreads its data across many computers, so hackers can’t gain anything from attacking one single place. The network also eliminates the need for a middleman. This decentralization makes transactions more transparent and secure.

The top 5 reasons why blockchain technology is the future are:

Blockchain technology has taken the world by storm, revolutionizing the way we store, manage, and exchange data. Here are the reasons why blockchain technology will revolutionize the world:.

1.Faster Transaction

Blockchain technology is decentralized and secure in nature; therefore, it becomes difficult for any nefarious party to tamper with transactions processed through the platform.

Data that is verified by blockchain is highly secure and trustworthy, meaning transactions can be processed much faster than in today’s world without compromising security.

2.Builds Trust

Building trust between different entities is utmost important and at the same time difficult since both businesses become vulnerable to data breaches. When two organizations are willing to engage in a business that involves sharing data and transactions, they choose a trustworthy mode. Blockchain offers a decentralized structure, which means that no one has authority over the blockchain network. It helps companies build trust and share data within an ecosystem where no one exclusively is in charge.  Blockchain also helps reduce the cost of financial services due to its decentralized nature, which increases efficiency and reduces the cost of processing transactions.

3. Individual Control of Data

In today’s world, anyone can access any data without requiring permission from the owner. Blockchain protects the data while allowing the rightful owner to control their digital data using blockchain-enabled smart contracts. Moreover, data in the blockchain is irrevocable, immutable, and cryptographically signed. Anyone can contribute to a blockchain and allow anyone to read from it. By doing so, everyone knows the originator or owner of all data, and most importantly, no one can change the authenticity and source of all data.

4. It is a self-contained system

The noteworthy aspect of blockchain technology is that it is a self-sustaining system. A human is not required to authenticate transactions, conduct background checks, or impose contracts. When we perform a transaction, the system verifies it and spreads the details throughout the nodes in a matter of seconds. The term “nodes” refers to the decentralized digital ledger. It keeps track of all transactions and provides data to connected devices.


Important databases are vulnerable to hacking. Because of the cryptography in the blockchain, the system can secure the transactions.

Each block has its own unique and private key, which is used for validation. If the data changes, the unique block key becomes invalid.

That is why blockchain is the way of the future. In the future, governments from all countries will begin to use blockchain technology to securely store the data of millions.

How does blockchain work for cryptocurrency?

Blockchain is the foundation of cryptocurrencies. The most common use of blockchain today is as the backbone of cryptocurrency. When people buy, exchange, or spend cryptocurrency, the transactions are recorded on a blockchain. Blockchain technology is a decentralized, digital ledger that records transactions across a network of computers.

Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger. The decentralized nature of technology ensures that no single entity can alter or delete previous transactions, providing a high degree of security and transparency.

Apart from that, in the case of crypto currency mining, blockchain plays an irreplaceable part. Mining is a complex process, but, in a nutshell, transactions are entered into blocks on the blockchain. The block is assigned some information, and all of the data in the block is put through a cryptographic algorithm.  

Blockchain vs. Cryptocurrency:


Blockchain and cryptocurrencies are two terms often used interchangeably. However, there is a significant difference between both of them.

Cryptocurrencies are digital currencies that use blockchain as a ledger for storing records of crypto transactions. However, blockchains have many uses beyond cryptocurrencies.

They are used for storing and accessing medical data, supply chain and logistics information, and financial records.

Similarities between blockchain and cryptocurrency:

1. Intangible: Both blockchain and cryptocurrencies are intangible by nature. Cryptocurrencies are intangible digital tokens that cannot be held physically like physical currencies. The blockchains used for storing cryptocurrencies do not exist in a single place or one physical data center.

2. Advanced: Both blockchain and cryptocurrencies are technologically advanced. Blockchain is the underlying technology behind cryptocurrencies. Blockchain is much more advanced and secure than traditional databases. Likewise, cryptocurrencies are more technologically advanced than physical or paper-based currencies.

3. Interdependent: Blockchain came into existence to record transactions of bitcoin, the world’s first cryptocurrency. All major cryptocurrencies have blockchains for recording transactions. If someone buys a new bitcoin, it is recorded in a bitcoin blockchain.

Differences between Blockchain and Cryptocurrency:

1. Inherent Nature: Blockchain is a storage technology used for saving data on decentralized networks. Whereas, cryptocurrency is a medium of exchange. A blockchain can be used for storing different types of information beyond cryptocurrency transaction records.

2. Monetary Value: All cryptocurrencies have a monetary value. But a blockchain does not have any monetary value.

3. Use: Blockchain technology has uses beyond cryptocurrencies. Blockchain can be used for recording transactions in banking, healthcare, the supply chain, and retail. However, cryptocurrency is digital money, which can be used for buying goods and services and for investment.

4. Mobility: Blockchain technology is decentralized and distributed all over the world. There is no single location where all records of a blockchain are stored. Cryptocurrencies, although held in blockchains, can be accessed via mobile wallets.

5. Transparency: Blockchain, being a public ledger, is highly transparent. Anyone can join a blockchain network and view the information available. On the other hand, cryptocurrencies offer anonymity. So, while anyone can see the source and destination of a transaction, no one can know who is behind the transaction.

What are the limitations of blockchain?

Blockchain technology has undeniably captured the attention of the tech world and beyond, offering the promise of decentralized, transparent, and tamper-proof systems.

It is a groundbreaking innovation with potential applications in numerous industries.

But along with blockchain’s advantages, there are some significant challenges that need to be overcome.



1. Scalability: Scalability is one of the biggest disadvantages of blockchain technology, as it cannot be scaled due to the fixed size of the block for storing information. The block size is 1 MB, due to which it can hold only a couple of transactions on a single block.

2. Speed and performance: Blockchain is comparatively slower than the traditional database because blockchain technology performs more operations. First, it carries out signature verification, which involves signing transactions cryptographically. The blockchain also relies on a consensus mechanism to validate transactions. Some consensus mechanisms, such as proof of work, have low transaction throughput. Finally, there is redundancy, where the network requires each node to play a crucial role in verifying and storing each transaction.

3. Power Consumption: The consumption of power on the blockchain is comparatively high due to mining activities. Keeping a real-time ledger is one of the reasons for this consumption because every time it creates a new node, it communicates with each and every other node at the same time. Every time the ledger is updated with a new transaction, the miners need to solve the problems, which means spending a lot of energy.

4. Difficulty in Data Modification: In blockchain technology, it is hard to add or modify data once it is recorded. Even though it is considered an advantage of blockchain technology, it is also one of its biggest disadvantages.  Considering its downside, the process of data modification requires rewriting codes and involves an extensive process. Too much stability can sometimes adversely affect systems. The major disadvantage of blockchain technology here is irreversible records and its demanding modification process.

5. Immaturity: Blockchain technology is only a few years old. That’s why people do not have much confidence in it, and they are not ready to invest in it yet. Several applications of blockchain are doing great in different industries, but it still needs to win the confidence of even more people to be recognized for its complete utilization due to the age factor.

6. Increased transaction costs: When blockchain first came into existence, transaction costs were almost free. With evolving times, it has changed. In fact, as there is no fixed regulation on the transaction fee, this is at the discretion of the transacting parties. So miners may choose to process the transactions based on who is paying more. This will either mean a higher transaction cost or slow processing of the transaction, which is a notable disadvantage.


Without a doubt, blockchain technology is the wave of the future. The beauty of blockchain is that something may be unique and stored digitally without requiring a physical counterpart, which means there are endless possibilities for contracts, wills, deeds, certificates, and, eventually, a digitally integrated global economy.


Answer: Yes, every crypto associated with a blockchain has data transactions to handle. In short, for any crypto, it is the backbone of any type of cryptocurrency coin.

Answer: Not really. All crypto uses the blockchain as a ledger for storing data for crypto transactions that happen online. Moreover, blockchain have other usage other those used in crypto, like supply chains management, medical data management, financial transactions in banks, etc.

Answer: Some of the major limitations of blockchain are speed, scalability, power cost for processing, and data immutability.
