What is Cryptocurrency


Explain the objectives related to the Cryptocurrency.

In this new world of technology where every operation is being digitalized, cryptocurrency can be state as the boon for the fund transfer system. The aim of this report is to bring light in the topic cryptocurrency and thoroughly explain the objectives related to the cryptocurrency. This report also introduces the Bitcoin that is the most popular cryptocurrency and in manner to prove the words, it has been chosen as the example. There are uncountable advantages of using this technology and some of them described in the below report. Besides of these advantages, there are certain disadvantages or issues with the use of cryptocurrency and the basic principles such as pseudo anonymous and decentralized system has made this technology that much popular and even these are the most critical issues that is stopping it from being spread and used as the primary source. 

Cryptocurrency can be defined in a simple way as, “just limited entries in a data base no one can change without fulfilling the particular conditions”. This seems to be an ordinary technology but in real it is very much complex and this is just a simple definition. It can also be regarded as the form of digital money that has been designed in a manner to be secured while transaction in many ways (Gamble, 2017). A currency is being associated with the internet using the cryptography technology, which is a process of converting legible information to a unique code that cannot be decoded easily, for tracking the purchases and exchange. For better understanding the Cryptocurrency, it is important to gain knowledge about the cryptography technology (Tekobbe & McKnight, 2016). During the World War II, cryptography was born for securing the communication network. It has been being evolved continuously since then with the elements of computer science and mathematical theory for making the network, communication, information, and money transfer much secured.

Cryptocurrencies are being popular because of its security level, level of anonymity as transactions made through cryptocurrencies cannot be reversed or faked, and charges are very low to use them that makes it more reliable than traditional currencies. The decentralized property that means availability for everyone is another reason for its popularity (Tekobbe & McKnight, 2016). There are certain links to the dark web that can be stated as an illegal activity and a consumer should overlook such topics before buying the currency. Bitcoin was the very first crypto currency that came into account in 2009 and right now, it is the best cryptocurrency that is being spreading into the market (Hughes & Middlebrook, 2014). As the technology is getting evolved necessity and availability of such technologies are also increasing that lead to the birth of more than 900 such cryptocurrencies on the internet that are being practiced right now.

Why Cryptocurrencies are Popular

Decentralized technology is being used in the cryptocurrencies for securing the mode of payment that is being made online and keeping them stored in a virtual bank without having an official account. This technology runs on the blockchain process, which is a distributed public ledger called that can be described as a record of the updates on the transactions and the left amount that is being held by currency holders (White, 2015). A process called mining, are being used for creating units of cryptocurrencies that involves usage of computer technology in manner to solve complicated math problems for generating the coins (Tudor, 2014). There are several brokers also present in the market, who can sell the currencies and help in storing and spending those using cryptographic wallets. Bitcoin, Ethereum, Ripple, Litecoin are some of the common cryptocurrencies that are being used in the present time (Scott, 2016).

It is a technology, which is based on cryptography that has been evolved in the World War II, and came in trend from last few decades. It can be stated as a technology that can be used to make encryption over the files that are about to saved on the internet and a proper decryption code is used to decode them in manner to stop being accessed by an unauthorized user (Hofer, 2014). There are two basic components of the crypto-technology that can be stated as: Public Key Cryptography and the Blockchain.

Blockchain can be described as the special form of ledger that can be helpful in keeping track of the evidences about who is holding what assets and that is the most hard to modify deceitfully. Pseudo-anonymity is the other important property of the blockchain that is an important aspect for cryptocurrency (English, Auer & Domingue, 2016). Blockchain technology cannot be described as the technology that is being used in all the cryptocurrencies rather it is being used only in decentralized cryptocurrencies that uses proof-of-stake and proof-of-work protocols. It can also be described as the “publicly reviewable ledger containing a verified record of every transaction”. Synchronization of blockchain technology is then very important aspect for using it efficiently that means blockchain, ledgers must be kept synchronized among each other, or it can also be expressed as “distributed consensus” that emphasis on the need of mechanism that prevents a client form accepting conflicting messages about the fake transactions and many more (Zheng et al., 2016). Another important topic in the cryptocurrencies is the “mining” and it is a little bit complicate what miners do in real. Three basic steps are being followed in a process that can be listed as:

  1. The hash (#): It can be described as the product of algorithm that is being used to turn data of a variable in a variable length into data of particular length.
  2. New proposed transactions broadcast block in the Bitcoin network (Gordon, 2017).
  3. Guessing of a random number by the miners that is being stated as “nonce.”

The Decentralized Property of Cryptocurrency

As discussed earlier this is the very first cryptocurrency that came into existence and currently most vital in the market that is capable of addressing the Byzantine General Problem. Bitcoin software helps in enabling a network for the computers in manner to maintain a collective bookkeeping using the internet that neither is in control of one party, nor closed that result in absence of central record-keeper (Shi et al., 2014). It is not only digital money; rather it is more important than that, which can be described as the sum of technologies that is creating an ecosystem. Bitcoin includes of the four main technologies (Davidson, Flippi & Potts, 2016):

  • Public transaction ledger
  • Decentralized peer-to-peer network
  • Decentralized transaction evaluation system and
  • A completely decentralized Mathematical Currency Issuance Mechanism

Following are the list of properties of the cryptocurrency:

Irreversible: The transaction made at the first place cannot be reversed or an user cannot get back the coins (money) after making confirmation for the transaction and it cannot reversed by any means or any authority (Osterrieder, Lorenz & Strika, 2016). There is also not much safety in this network and no one could even help if any hacker steals the funds or by mistake, an individual transfer to other account. This leads to the less reliability on this technology.

Pseudonymous: It emphasis on using the service without having a real world identity and an individual does not need any government proof to open an account and share money. It can be a random individual, who transfers the money or the identity that is being used can be fake.

Fast and global: The transactions that have been propagated do arrive for an instances and a user have to confirm it within a couple of minutes (ElBahraw et al., 2017). This is being happened in the global network of the whole world network of the computers they are completely indifferent of the physical location of the users irrespective of the distance between the two consumers.

Secure: In general, Cryptocurrency funds have been locked in the system of a public key cryptography that results in the access of the transfer of the currency by the user only who is the right owner of that currency. Proper encryption and cryptography technology makes the currency to be inaccessible by an unauthorized user. Bitcoin is much more secured cryptography than Front Knox cryptocurrencies.

Permissionless: No permission is needed to access, as it is available for every user that is connected to the internet (Ahn et al., 2016). It is software easily available on the Web and anyone can download it and access it. You don‘t have to ask anybody to use cryptocurrencies.

Bitcoin: The Pioneer of Cryptocurrency

Besides of all of the features and advantages there are certain issues related to the practice of cryptocurrencies that can be listed as:

Insecurity: As stated earlier transactions are reversible that also eliminates the most important factor of making business that is “reliability, and “loyalty”. There not any such service whom you can call and discuss about the transaction and get your refund if any fraud happens (Hsieh, Vergne & Wang, 2017). It aims at pseudo anonymous and decentralized that makes it vulnerable to be hacked by the hackers and stolen in unauthorized way. 

Volatility: Since the market of bitcoins are very much volatile in nature (as in between January 2015 and November 2013 50% value collapsed) it is not preferable for long-term use.  Price fluctuations will affect the business and money cannot be recovered during low markets.

Money is created at a depreciating rate: most of the cryptocurrencies do not follow the economic principle of money stated by the government and money is being created at a rapid depreciating rate.

Proof of work: The energy consumption that needs to be maintained while the process is going on has been criticized by for the hardware arms race that has been created by it (Cocco et al., 2017).

No inflation/ limited supply: it is an issue related to the economic effects of the cybercurrencies reaching its final detrimental effect of the absence of inflation in the whole system.

Confirmation time: This is another issue related to the use of cybercurrencies as most of the servers provides at least ten minutes for the confirmation of transaction.

Blockchain “Bloating”: blockchain is nothing but a file as more transactions are being done more the size of the file will increase.

It should be operated by the organization irrespective of the independent organization and should be based on the government policies of finance and economy. The account should be opened with proper identity defining the permanent address of the user. The transaction should be made reversible and there should be customer assistance service for the contact if a user feels the act of fraud. Another solution related to such issues can be proposed as the network should be made secured and any user entering the network should be recorded with their virtual address of the computers (Bonneau et al., 2015). From the perceptive of the user it can be recommended that he or she should cross check all the objectives before making any investment and check whether he or she is being framed for any fraud or not.

Properties of Cryptocurrency

There are two very crucial components for the security in cryptocurrencies and the first part focuses on the difficulty that is being faced in finding hash set intersections that is being done by the miners. The second crucial component can be described as of the two cases is a “51%” attack (Schaffner, 2015). For an instance, the miner capable of controlling the mining in more than 51% of the network has the capability to alter the blockchain and he could generate an alternative block-chain for the same network. Through achieving the objective a user will be able to revise the transactions made by him and will be capable of blocking other transactions (Yang, Kou & Liu, 2017).

It can be stated that the market of cryptocurrencies is wild and fast. Every day thousands of transactions are being made and lots of investor losing or gaining money from the cryptocurrencies. Some of the users survive for the first month “and most are pumped and dumped by speculators and live on as zombie coins until the last bagholder loses hope ever to see a return on his investment” (Gipp, Meuschke & Gernandt, 2015). Besides of all the facts related to the disadvantage of cryptocurrency it has the capability to change the future and it can be experienced that it is changing the face of fund transfer. Most of the retailers and customers are using Bitcoin as the media to exchange currencies and trying to be protected against the devaluation of their national currency. Most of the Asian companies are using Bitcoin and are using darknets of flourishing and cybercrime.

The technology is being evolved and in future, it is being estimated that it will eliminate the banking and physical money transaction. Institutional investors have also started to buy the cryptocurrencies.


Based on the above report it can be concluded that, as it had been appeared very early, even that it is a very new technology for most of the sectors and cryptocurrencies are being technically much advanced. Most the systems, which are responsible for the proper functioning of the society had been centralized and are not accessed on pseudo anonymity rather it is based on these principles. People always fear the change and want to be stick with the traditional methods irrespective of the advantages and facilities or ease to access.  This report shows how cryptocurrencies can change the face of the fund transfer in the world. With respect to the disadvantages, there are certain measures that could be taken but they seem to be impractical in the real world. There is the extreme need of a responsible authority that could help in making this system a systematic transactional method and much secured. In other words, it can be said that it is the necessity of the time for such technology but certain authority that can give guarantee on the processes should centralize it. Cryptography technology is being used to make the transaction secured but there should be a refund system for the users. This technology is highly vulnerable to cyberattacks as most of the users are connected to the dark web, which can be described as the dark side of the internet. There are certain examples like the cases of ransomware attack have been increasing continuously day by day and intruders are using cryptocurrencies as a medium to achieve success in looting others.

Issues Related to Cryptocurrencies

Making cryptocurrency a centralized system can be recommended to make this as the basic system that can be used by everyone and make the system more secured. It should be made as the basic medium for exchanging the currency. Retailers are using it but it should be implemented within the systems of each retailer.
