What is Cryptocurrency, Its Uses and Why use it?

Cryptocurrency is the latest buzz of the financial market. Bitcoin was the first cryptocurrency to enter the market; many others followed the trend with the success of Bitcoins. It will be not wrong to point out that all great inventions were accidental, so the case with Bitcoins. Satoshi Nakamoto invented Bitcoins cryptocurrency. He was trying to develop an e-cash system under a project in 2008, with no central server, so he devised a decentralized electronic cash system. Cryptocurrency uses a peer-to-peer network to share the information to eliminate the need for the centralized system. Cryptocurrency is not rocket science to understand. They are databases stored in a decentralized ledger which record the transactions that cannot be changed or altered by anyone as Blockchains protect them. Authorized users can only change them if certain conditions are met. Cryptocurrencies are entries of tokens stored in a decentralized database with records of all account balances. Advance cryptography techniques protect the blocks.

How Cryptocurrency Works?

Cryptocurrency data stored in a decentralized public ledger, so the transparency is maintained. This also eliminates the risk of double spending by the user. Nobody owns or controls the ledger, its self-running without any interference of a central authority or a third-party. When a transaction is done in Cryptocurrency, it goes through a verification process. Cryptocurrency miners verify the transactions and add them to the Blockchain powered public ledger. Power supercomputers are used to solve the cryptography mathematics which is the key essence of the verification process.

Cryptocurrency mining is open-source, so anyone can confirm the transaction and the first miner to solve the problem gets to add a block to their transaction ledger. This process of verifying transactions is known as “proof-of-work-system.” Use of digital signatures prevents any forgery. Everyone is allotted a private key and a public key. The keys are protected with 256Bit encryption which is impossible to crack. Blockchain Technology protects the data blocks from any kind of tampering and unauthorized access.

Advantages & Disadvantages of Blockchain Technology

The USP of a Blockchain Technology is that it permits a database to be shared directly without a central administrator to its associate members to bring transparency in the system. Rather than having some centralized application, Blockchain transactions have their self-proof of validity and authorization. Blockchain has the capacity to change the business style of today and also improve efficiency in the management of an organization. Moreover, it works on computer networks that are connected to a central point without the interference of a third-party. Blockchain Technology and its apps are being developed daily on a broader scale and are considered to be the most effective tool of the decade. Industry can learn more through Blockchain Technology because it gives some advantages as well as disadvantages which we will discuss in brief:


The crucial advantages of implementing the Blockchain Technology for the industry are:

  1. Decentralisation: This is one of the primary benefits of this technology because, in a Blockchain powered system, the need for third-party or intermediaries is eliminated by its working mechanism that manages the process of validating, verifying and clearing the various transactions.
  2. Trustworthy: A distributed ledger in blockchain technology records all crucial transactions in such a manner that they are readily available to all the blockchain members. As now the ledgers are being shared publicly, this brings more transparency and trust in the entire system.
  3. Simplification: Present working model in various organizations, in whichever sector like automobile, healthcare, banking, etc. every department is maintaining their own databases. Blockchain technology serves a single shared ledger that makes data sharing fast and simpler involving all departments.
  4. Faster Trades: Any kind of trade or contract has to pass through a various verification process before reaching its final destination. Blockchain technology can assist in saving time here, by offering single ledger to all the associated parties by providing faster settlement of trades.


With some crucial advantages, Blockchain Technology has some drawbacks too for an industry:

  1. Nascent Technology: With having several benefits of Blockchain Technology, the primary disadvantage of this cutting-edge technology is that there are some nasty challenges like transaction speed, the verification process, and data limits should be resolved before making blockchain widely applicable.
  2. Uncertain: As most of the modern currencies of today have been created and regulated by national governments, financial institutions, etc. Blockchain or bitcoin face a hurdle in widespread adoption as their financial transactions would be restricted because not authorized by the government institutions and as a result remain unsettled.
  3. Higher Costs: Developing a Blockchain into your organization is not an easy task, it involves massive energy consumption, a decent amount, colossal capital cost, etc. that might be not possible for medium scale as well as low scale businesses. It is a fact that it offers tremendous savings in transaction cost, but at the same time, its implementation cost is too high.
  4. Power Use: The consumption of power in the implementation of Blockchain Technology is comparatively high. Keeping a real-time ledger is one of the underlying reasons for this higher consumption because every time it produces a new node, it communicates with every node at the same time.
