The aim of this paper is to review the blockchain technology and its benefits in relations to education system. Blockchain technology is widely researched and highly evaluated and appraised for its unique infrastructure. In general, blockchain researched for its association with Bitcoin and cryptocurrency advantages. In this survey the plan is to conduct a full review of previous literatures focused on blockchain in education systems. Provide overall reviews of blockchain concepts and architecture behind the technology and to examine verification software that used by the technology to improve security and immutability. Brief discussion on the consensus algorithms and hashing function and how these operate and difference type of blockchain will be discussed. In this survey, the existing technology used in Saudi Arabia will be reviewed. In-depth research conducted for over 70 papers, of which 35 noted in this survey. Blockchain emerging promise a real time democracy and justice to all users over the world. Educational Industries said to revolutionize its communication system and accessibility and extend their market globally by widening their admissions and providing secure cost-effective, transparent and immutable communications across their educational platforms.
Blockchain is an emerging technology that has many uses and applications among many industries such as banking, education, and tourism. It has proven over time to be more cryptographically secure than traditional databases. Many people confuse Bitcoin with Blockchain. Because of the considerable value of Bitcoins, people have the perception that blockchain technology requires large computing infrastructure and power due to CPU bottleneck challenges. This paper presents the process used in testing blockchain technology performance on a virtual machine by focusing on benchmarking workloads like CPUHeavy using Ethereum blockchain and comparing two different algorithm sorts, Quick and bubble. The results of the testing indicate that blockchain workloads can be performed on smaller machines with very little CPU bottlenecks. In addition, performance test outcomes found that the CPUHeavy and Quicksort was more superior.
"Cryptocurrencies have become the buzzword among society, especially after some prominent companies such as Wikipedia, Microsoft and Amazon accept the use of cryptocurrencies. Nonetheless, accounting treatment of cryptocurrencies appears to be a challenging area for standard setters, financial statement preparers, and also users. This is mainly because elements of cryptocurrency do not explicitly fall under any existing accounting standards. The fact that cryptocurrencies are held for different business models and intentions may affect how it should be treated under accounting standards. Hence, this research aimed to examine factors that affect the accounting treatment of cryptocurrencies in Malaysia. Different factors were examined including the function of cryptocurrencies, conceptual framework of financial reporting and the legal status of cryptocurrencies. Targeted respondents involved in this research were accountants in Malaysia. Data collected were analysed using SPSS and SmartPLS 3. SPSS was mainly used to analyse the demographics of respondents whereas SmartPLS 3 was used to carry out reflective measurement model and structural model evaluation. The results concluded that all the independent variables which are the functions of cryptocurrencies, conceptual framework of financial reporting, and the legal status of cryptocurrencies have a significant relationship with the accounting treatment of cryptocurrencies. The results of this study provide an insight about factors that standards setters and financial standards should consider when accounting for cryptocurrencies’ transactions in order to provide faithful representation and relevant information. Some limitations and suggestions are included in this research to provide ideas for future researchers to carry out further research. Keywords: Cryptocurrencies, Accounting Treatment"

The application of Blockchain technology has begun to be widely accommodated in industrial and business practitioner environments as a safeguard of transaction security so that now including the education sector, non-business institutions enjoy the use of this technology to support the learning process. Information on the protected Blockchain can be in the form of transactions, assets, identities, and other information packaged in digital form. Information is collected in the form of blocks that are interrelated by using the hash function as cryptographic encryption. This research uses Blockchain for online pocket money top-up transactions for students. The use of a centralized Blockchain is centralized to reduce server procurement costs, but to increase the security of transaction information, modification of each block series is carried out using the AES cryptographic approach. The results showed that the attack by inserting a Cross-Site Scripting (XSS) script if you want to know the value of the top-up transaction amount, you must be able to hack the cryptographic process. This is supported by chain validation testing to determine how many block changes have been changed.

Teknologi Cryptocurrency saat ini sangat berkembang ditandai dengan banyaknya orang yang mau berpartisipasi untuk menjadi bagian di dalamnya. Salah satu Cryptocurrency yang terkenal adalah Bitcoin. Namun, bagi sebagian orang tentu tidak mengerti apa itu Bitcoin dan bagaimana cara kerjanya. Sehingga, hal itu membuat mereka ragu untuk ikut turut serta menjadi bagian dalam teknologi ini. Sehingga perlu dibuat sebuah analisis sentimen mengenai teknologi ini sehingga dapat memberi pengetahuan apa itu sesungguhnya Bitcoin. Melalui Twitter, analisis sentimen dapat dilakukan guna mencari tahu bagaimana pendapat banyak orang mengenai Bitcoin. Hal ini dapat dilakukan dengan memanfaatkan API yang disediakan oleh Twitter untuk mengumpulkan data berupa tweets. Kemudian, melakukan analisis sentimen menggunakan library Python untuk mengklasifikasikan suatu tweet menjadi positif, negatif, atau netral. Dari hasil klasifikasi menggunakan dataset yang berjumlah 3433 data didapatkan bahwa 41,3% diklasifikasikan positif, 44,9% netral, dan 13,7% negatif. Lalu, untuk visualisasi dari keseluruhan pendapat orang-orang mengenai Bitcoin dapat dibentuk dengan menggunakan Word Cloud sehingga hanya akan muncul kata-kata penting yang berhubungan dengan Bitcoin. Diharapkan setelah penelitian ini dilakukan dapat dilihat bagaimana pendapat orang-orang khususnya pengguna Twitter mengenai Bitcoin.

Pengawasan jaringan pada beberapa kantor yang berlokasi berjauhan sangat sulit dilakukan kerana keterbatasan tenaga ahli, biaya, dan teknologi pendukung. Penelitian yang sudah ada tidak dapat menyediakan sistem pengawasan jaringan yang mampu menjamin tiga aspek keamanan sekaligus, yaitu: availability, integrity, dan confidentiality. Teknologi blockchain mampu menyediakan sistem pengawasan jaringan secara terpusat dan aman dengan menjamin keamanan sistem komunikasi pelaporan dan sistem basis data pelaporan. Penelitian ini bertujuan untuk menyajikan purwarupa sistem pengawasan konfigurasi dan statistik jaringan menggunakan jejaring blockchain Ethereum. Metode pengawasan mengharuskan program controller pada setiap jaringan kantor untuk secara berkala menarik informasi flow-rules dari setiap perangkat jaringan dan melaporkan data tersebut dalam sebuah transaksi ke jejaring blockchain. Pada penelitian ini dianalisa dua jenis skema pengiriman transaksi: transaksi berbasis smart contract dan transaksi berbasis zero-payment. Berdasarkan hasil pengujian, transaksi berbasis zero-payment secara rerata hanya membutuhkan sekitar 6 % dari biaya transaksi smart contract. Perkiraan biaya bulanan untuk pensamplingan informasi setiap 10 menit adalah sekitar 1,19 ether per-perangkat jaringan. Meskipun demikian, metode pada penelitian ini lebih sesuai untuk diterapkan pada jejaring Ethereum jenis Proof-of-Authority (PoA) dibandingkan jenis Proof-of-Work (PoW) karena harga Ether yang mahal. AbstractCentralized monitoring of remote networks is hard to implement due to the high cost, lack of experts, and the missing key technologies. The existing researches are unable to provide a secure, centralized monitoring system that satisfies three security aspects, namely: availability, integrity, and confidentiality. Blockchain technology meets those three requirements by providing a reliable reporting and immutable database system. In this paper, we proposed a prototype of a centralized monitoring system that records network statistics and configurations into the blockchain ledger. The method requires the network controller to periodically fetch network information from every network device and submit it as a single blockchain transaction. We compare two kinds of transaction schema, smart-contract based and zero-payment based reporting schemes. The evaluations show that zero-payment transactions only cost 6 % of the smart-contract transactions. The estimation of the monthly cost is 1.19 ether per-device for 10-minutes data sampling. Nevertheless, the proposed method is applicable only for the Proof-of-Authority (PoA) Ethereum networks. It is not feasible for the Ethereum main network that uses Proof-of-Work (PoW) due to the high cost of Ether.

Abstract Over the course of time, electronic voting has evolved as a substitute for paper ballot voting to decrease redundancies and inconsistencies. Due to the many security and privacy vulnerabilities experienced over time, the past results of e-voting in the last three decades indicate that it has not been very successful. All cryptocurrencies are actually based on block chain. Block chain is based on the principle of distribution and decentralization. It is a continuous and continuously growing ledger that holds, in a secure, chronological and immutable way, a permanent record of all the transactions that have taken place. Value in a block chain can be anything. In the case of cryptocurrencies, it takes the meaning of money or currency. While in a game it takes the form of points or score. The value can take the form of a vote or a ballot while e-voting. The blockchain can be used in this article to pass votes between two parties. In our case, the electorate is one party and the candidate who earns the vote is the other. Without having a controlling central authority body, the block chain can be implemented in a more stable manner in mass electoral voting practise. A voting system that uses a more stable, tamper-proof block chain (immutable to voting modifications either by other voters or by any third party) and is cost-effective.
The study aims to elaborate on the Shari’ah issues regarding cryptocurrencies. The research found that overall Shari’ah challenges in studying this unprecedent issue can be confined to Bitcoin since it is the first cryptocurrency with its own protocol and laws, and the later versions of the cryptocurrency started using the protocol of Bitcoin. Bitcoin was distinguished being the only cryptocurrency that is classified as decentralized, whereas the subsequent versions of the currencies, which were introduced as an alternative to Bitcoin, such as Ethereum, were centralized by their issuer. Also, the tokens are merely representing the assets which were collected through it. The overall Shari'ah issues were summarized in terms of its asset and monetary consideration, impact of price fluctuations, decentralization, anonymity, and the mechanism of mining which PoW (Proof-of-Work) and PoS (Proof-of-Stake). This study has concluded on the Shari’ ah permissibility of the PoW system which is used in Bitcoin, and PoS system which is used in Ethereum. The contract is based on Ju’alah contract. As a principle, the study could not conclude the Shari’ah non-permissibility of exchanging, trading or investing in Bitcoin, and similar cryptocurrencies. These cryptocurrencies are subjected to all the guidelines related to exchange of currencies (sarf) and rulings of Riba buyu’ (sale on credit) and Riba duyun (interest on debt). Also, it will be subjected to monetary Zakat rulings. However, dealing with mining groups, electronic platforms, as well as investing in these currencies through various websites, may contain executing agreements and contracts that contain conditions not compliant to Shari’ah. These agreements should be examined in the light of the provisions of the Islamic law. Also, users should be cautious against falling into the net of fraudsters on the Internet. The research recommends to hold-up investing in these recent currencies because of the rapid volatility and to avoid exposing the wealth to high risk.
Recently, Blockchain technology has attracted great attention in both private organisations and the public sector around the world. However, not many are aware and understand this new technology. Thus, lack of understanding of the Blockchain technology could influence the intention in adopting the technology. Therefore, the objective of this paper is to identify the behaviour intention towards adopting Blockchain Technology in the Malaysian Public Sector. Data were gathered using a questionnaire to analyse the relationship between factors such as Performance Expectancy, Effort Expectancy, Social Influence, Facilitating Conditions and Trust with Behavioural Intention to adopt Blockchain Technology. The data were gathered from 100 officers in various government department. The survey revealed that majority of the government officers are aware about the Blockchain technology. However, most of them have inadequate exposure and knowledge about the technology. Findings from the regression analysis found that Trust, Performance Expectancy and Social Influence positively and significantly influence the behaviour intention of government officers in adopting Blockchain technology. Meanwhile, Effort Expectancy and Facilitating Conditions were found not significant. The findings from this study suggest that it is essential to develop strategies to implement a suitable Blockchain application in the public sector. Prior to such implementation, it is imperative for government officers to be equipped with knowledge, skills and resources related to the Blockchain technology.
On a daily basis we deal with documents like educational records, health records, certificates etc. Medical records are still being stored on legacy systems which carries the risk of losing important documents. There are security and privacy concerns regarding the safety of documents on centralized server. To overcome these difficulties, we made a blockchain based record storage web app through which anyone upload their medical records on the blockchain and can access them with a private key. The patient or the user can download and access reports from anywhere and can also manage to share them with his doctor etc. Blockchain is a decentralized, distributed, peer to peer ledger on the internet. Blockchain technology helps to maintain security and reliability without placing any trust in a third party. The use of smart contracts in blockchain helps in making things much easier. This paper examines the record storage system including the technologies involved and the methodologies. The approach used for making an electronic health record storage web app through which we can implement a more broader record storage system that can store and manage numerous types of records.

Blockchain is a public ledger technology to which everyone has access without a central authority having control. This technology typically gets to use registration and smart contract. To make sure there are security and authenticity in the transaction information in blockchain, many researchers are study on consensus algorithm. There is a lot of consensus algorithm are using in blockchain. Determining leading research area and finding the best key of consensus algorithm is the motivation of this study. Thus, this study will investigate how consensus algorithm areas of research can be determined by study on the Proof of Stake (PoS) and Delegated Proof of Stake (DPos). Besides that, this research study about the key parameters that being using in these two algorithms. In addition, after getting the parameters we measure the comparison in terms of their transaction per second, nodes, and block sizes. Furthermore, we conclude the efficiency of these two algorithms in terms of their scalability. Although DPoS performance is expected to be much better than PoS, the impact of parameters can be assessed and analyzed to see and prove results. We hope after this study, can solved the performance and security affected by the application of consensus algorithm used in the blockchain.

<span>Tracking drugs became more difficult using the centralized architecture. Decentralized architecture using blockchain technology overcomes the difficulties faced by the centralized network like availability and recovery. Avoiding duplicate or fake drugs created by fake manufacturers is a big challenge in the centralized network. Authentic stock is managed and the supply chain is tracked efficiently using this blockchain technology. This is addressed by using the smart contract which helps to track the movement of drugs from manufacturer to supplier, supplier to the reseller, reseller to pharmacies and finally pharmacies to patient. By default, duplicate drugs or fake drugs are completely avoided by using the blockchain technology. Patients buy drugs without any prescription and it creates a lot of problems in real life. So, Patients cannot buy drugs without authenticated doctor’s prescriptions with the help of a QR Code scanner attached with the prescription which will be implemented using a mobile application and cannot buy excess drugs which might lose someone’s life. With the help of inventory management, the maximum limit of drugs to avoid overdose and pharmacies cannot sell those overdose drugs. Consulting a doctor before buying a drug for even a simple illness is important and it is tracked by using prescriptions provided by authentic doctors. In this project, these challenges are addressed using the smart contract which is written in solidity language and runs on a public ethereum network.</span>

This research aims to learn why Blockchain Technology can be the most demanding hard skills in companies in 2020 as quoted from LinkedIn and the positive impact that Blockchain Technology has on a company. If we see, at this time usually requires at least a third party to make a transaction, and a company usually only stores data / information on a centralized server which makes the data easy to hack. From this case, Blockchain technology can be used as a way out for a company to make data / information not easy to be hacked. Because, Blockchain uses a distributed server system that is validated, which makes Blockchain safer from evil parties who want to hack information, and Blockchain has other advantages such as more cost-effective, better transparency and traceability. Therefore Blockchain Technology is a particular attraction for a company and is the hard skill most demanded by the company in 2020.

Perdagangan merupakan sebuah kegiatan tukar menukar barang atau jasa yang dilakukan manusia untuk memenuhi kebutuhan hidup. Perkembangan sistem pembayaran yang dilakukan umat manusia dimulai dari sistem pertukaran barang atau barter, logam mulia seperti emas dan perak, koin, uang kartal, uang giral, dan uang elektronik (e-money). Selain itu, muncul cryptocurrency yaitu mata uang digital dengan sistem kriptografi dalam setiap proses transaksi datanya tanpa melalui pihak ketiga. Namun cryptocurrency memiliki kelemahan perubahan harga yang sangat besar dalam waktu yang sangat cepat. Pergerakan harga yang berfluktuasi sangat tinggi tersebut menyebabkan kekhawatiran pemilik aset kripto mengalami kerugian, maka pemodelan harga cryptocurrency sangat penting untuk dilakukan agar meminimalisir risiko kerugi-an. Berdasarkan pola pergerakan harga yang berfluktuasi sangat tinggi yang berbeda tiap periodenya maka dilakukanlah pemodelan harga cryptocurrency mengguna-kan Markov Switching Autoregressive (MSAR) dengan algoritma Expectation Maximization. Selain meminimkan risiko kerugian, penelitian ini juga ingin mengetahui model MSAR mana yang mampu mengklasifikasikan state dengan baik. Data yang digunakan yaitu harga harian cryptocurrency dengan nilai kapitalisasi pasar terbesar dari September 2015 hingga Januari 2020. Hasil penelitian menunjukkan bahwa bitcoin dan ripple menggunakan model MS(8)AR(1), sedangkan ethereum menggunakan model MS(9)AR(1). Selain itu model MS(8)AR(1) pada data ripple menjadi model dengan nilai akurasi tertinggi dibandingkan model lainnya dalam hal klasifikasi state.
Blockchain will be the future of accounting education. Triple entry accounting system is here, and shared ledger has been considered. From the shared ledger different parties can access transactions. As our discussion reveals that distributed ledger, Smart contract and Blockchain are three important elements in the triple entry accounting system. As a result, blockchain technology is helping the upgrading the process of education system. Blockchain technology is a peer to peer communication that allows participants to secure the settlement of transactions, achieve the transactions and transfer of assets at low cost. With certain advantages there are disadvantages too. Based on performance and acceptance, it is clear that in future the implication of blockchain technology would be developed. The concept of triple accounting has introduced the new way of accounting work replacing accounting standard formula. The blockchain technology eliminates the involvement of third party, maintain transparency and charges low transaction cost. It will save money and time of people as it is secure and due to decentralization, it is not controlled by one single entity. Due to the decentralization, every user of the network can see the file. So, blockchain should the part the Accounting Education in future.
