Running Head: Classification 1

A study was conducted to build up an extensive classification of the types of use of research markers which can be applied in quantitative examinations. The classification was derived from the data on research about markers use given in the diary writing in the field of scientometrics/bibliometrics.

Researchers showed the various classifications in the classification in terms of examples from which the classification has been inferred. By use of this methodology, researchers as well gave a picture of recent study which mention the utilization of research performance markers.

Study Outcomes

The review of the current application of research pointers exhibited in the study uncovers the pertinence of information coordination and interoperability: there is such a variety of application, that no single marker can serve every one of them, nor is it likely that any marker is valuable for only one of these reasons (Celeux & Murphy, 2019).

This implies most purposes must be served by a mix of markers and that, simultaneously, numerous markers will fill a few needs however together with various mixes of different markers.

This, thus, implies it is profoundly alluring that information from various sources and various pointers can be identified with one another, and share normal definitions and characterizations so they can be used together.

Study results likewise uncovered that the information sources and markers are characterized by our classification of sorts of use.

This demonstrated where similarity or ‘relatability’ is generally required and what sort of activity has furthest significance. Hence, on the off chance that things being what they are, a specific set of markers is frequently used with the end goal of the allocation of financing to colleges, at that point it bodes well to organize the work on a typical depiction of colleges in this set markers and the core information sources.

Subsequently, the stupendous moves presented to the present foundation can be tended to all the more effectively and even be guided by utilizing our classification of types of use.

Role of Classification

Classification is used to classify user profiles and generate tailored feeds automatically for a certain user starting from his interests. A simple classification method is Naive Bayesian classification that uses conditional probability. I am also used for recognizing spam emails and automatically discarding it in the spam box (Jiang & Shekhar, 2017).

Also, K-nearest-neighbor is another algorithm used to classify new entries based on their features. In financial sector, classification is used to determine if a transaction is deceitful or in some way violating some guideline. That is a classification pattern due to the fact that most of the time you will try to match against a pattern, which might not be 100% correct.

In finance, time is of essence hence you must be able collect data, run a model, and deliver desired outcome at the same time to be able to monetize any possible opportunity. Clustering algorithms can also be used to classify documents based on their content.

One of the most famous is K-means. LDA method is also a way for classifying text from a semantic point of view. All those classifiers are first trained with labeled data (Vidales, 2019).

It means that they learn from the labeled data how to do their task. Fitness wrist bands such as fit bit ones are trained to recognize user’s activity such as walking, cycling, running or sleeping. This way they can measure and report activities with great precision.

Bitcoin Blockchain 7

ITS 836 Data Science & Big Data

The biggest problem facing the Bitcoin community today is the political in-fighting and it’s potential to split the blockchain. Right now, Bitcoin has many advantages in the market, including being the most well know cryptocurrency, being the most supported fiat-to-cryptocurrency exchange method and being the largest blockchain by market cap.

While Bitcoin is not innovating as quickly as other blockchains, they are making a good attempt at being the go-to cryptocurrency for investors. So long as no one rocks the boat, they can maintain this momentum. However, if a failure happens with the Segwit transition and the chain splits, all of this momentum can be halted.

The problem comes down to a lack of leadership. Since the departure of many key figures in the Bitcoin community, most importantly Satoshi Nakamoto, there is a distinct lack of moral authority around the community. Instead, you’re seeing a lot of foul play and high visibility exits with no one leading the ship. If Bitcoin is to survive unscathed, they need a strong figure to re-emerge and start directing action.

Challenge Facing Bitcoin Blockchain

Slower Transactions

One of the biggest challenges before Bitcoin is the issue of slower transactions. The duration for a transaction to be approved has increased drastically (Crypto Scores, 2018). This has made Bitcoin take a hit. A number of businesses, who were initially very enthusiastic about Bitcoin, have stopped accepting Bitcoin.

The issue of slower transaction was always around the corner since 2009. And, this only adds to the misery that how did the developers fail to come up with a solution until now. The average time taken for a Bitcoin transaction to be verified and approved is 43 minutes. And, there is a possibility that some Bitcoin transactions remain unverified forever.

The reason behind this is the transaction fee. Those who offer higher transaction fee gets verified before others who do not. This leads to formation of a queue in the list of transactions.

This becomes painful for those who pay less or do not pay transaction fee. They are kept in waiting for hours and in very few cases, for even days to get their transaction completed or verified. This has enabled other cryptocurrencies such as Litecoin to eat up the market of Bitcoin.

Expensive Transactions

Every transaction through blockchain is subjected to a transaction fee which creates a queue. The order of business changes according to the highest payer. In simple words, whoever pays the highest amount for transaction fee gets their transaction approved before other.

So, if a person has to send the money across instantly, he/she will need to pay an extraordinary amount of money which will directly make the whole transfer expensive (Shi, 2019). This has been widely criticized by people and analysts around the world. This has led a number of people to search for alternative options in cryptocurrencies.

Privacy

Since Bitcoin operates on a public blockchain, it does not offer privacy. This drawback of Bitcoin has been used by other cryptocurrencies as their unique feature. A large number of people want privacy in transaction and hence considering a switch. Contrary to popular misconception, Bitcoin is not private but anonymous.

No Bitcoin transaction is encrypted, each transaction is hashed. So, every transaction is public. In place of counting this as advantage, the point has been advertised by others as a disadvantage. Rival cryptocurrencies have addressed the same to their profit.

Bitcoin Technical Challenges

Blockchain is decentralized, this implies that no one is responsible for system security as well as maintaining. In blockchain, every node can secure the system by processing transaction. Blockchain transactions are directly linked to the user hence anyone can create a new wallet secretly and can transact through that wallet (Ahmed, 2020).

Identity verification data like security numbers that cannot be openly stored in public smart contracts. Credential management is another factor which is not managed in an open, ultimately unsecured smart contracts.

Formal authentication of smart contracts is a big issue in blockchain. Formal verification is used to determine whether the program behaves as per the specification or not.

of the main issues with implementing blockchain into everyday lives is with the fact that all the projects, companies, firms etc. that utilizes Blockchain have made it seem too technical hence it stands out as something for only the tech people. The term blockchain alone scares the common man because of the way it has been presented.

Also, blockchain platforms don’t have any centralized authority to control and it’s completely trustless and open system where no one responsible for setting and maintaining standards.

Solving Bitcoin Blockchain Challenges

Testing has become the most important aspect in success of implementation of blockchain Technology due to decentralized peer to peer architecture with shared ledger available to the network nodes.

This ensure that all the transactions are capture within the block which is continuously and securely linked to chain. Blockchain technology apply Smart Contract rule which is absolute, means once implemented it stays permanent (Michaud, 2018).

In an event a newer version of the contract is comes up, due to production error, then manual transfer of stored data is needed, which is a tiresome process. Blockchain application requires all the standard testing and validations such as functional, integration, security & performance with specialized testing as well as Smart Contract testing, Node testing, & advance level non-functional testing.

Integration testing – Blockchain always works with integration of other interfaces so key obligation is to facilitate consistent feedback from all nodes and avoid any system failure. Proper information should be provided to the testing team for all interfaces along with their response status.

Performance- Performance testing is challenging for blockchain as it is very difficult to replicate production like environment for performance testing. It needs to be tested for network latency in relation to node size, network range, possible transaction rate and time it takes to process a transaction. Blockchain platform performance, scalability and stability

Security – it is critical to determine network integrity at all time. All blockchain transactions are encrypted but once the identity layer is compromised the instant transaction cannot be stopped. In security several testing must be done such as blockchain access testing, secure hash algorithm testing, blockchain wallet signature testing.

Conclusion

Blockchain might be one technology but it has applications across multiple industries. Whether we talk about healthcare or finance, politics or manufacturing, there are ways to implement the technology in different ways. For instance, transparency and accuracy in voting can be achieved with tokenized votes in any major election.

In the same way, banking services can be made more accessible, affordable, and faster with cryptocurrencies. There are many other applications of blockchain and change has already begun.

It won’t be wrong to assume that a major shift in blockchain adoption can be observed within the next 5 years. Blockchain can possibly change the manner in which all industries operate, especially the manner in which business transactions are conducted as well as verified.

It will be easy for organizations to find the right people to fill a certain position within the organization as there will be a database containing this information. Vetting and screening candidates will be easy.

The social effect of blockchain innovation has just started to be acknowledged and this may simply be a hint of something bigger. Cryptocurrencies have just created doubts over financial services through computerized wallets, the rollout of ATMs and the arrangement of advances and installment frameworks.

While considering the way that there are in excess of 2 billion individuals on the planet today without a bank account, such move is surely an actual life changer and must be a positive one.
