Cryptocurrency is a form of digital storage that uses cryptographic techniques or secret passwords. This cryptocurrency is not controlled by an institution such as a bank, country or certain company but uses a decentralized server and cryptocurrency uses a system that cannot be controlled by anyone because it uses a network that can document transactions directly, without any third party. This review expects to get a thought meaning of Cryptocurrency and how the assessment of the researchers on it depends on sharia and Islamic law. This examination is a writing study. The information wellsprings of this examination were taken from the Qur'an, the hadith of the Prophet, traditional and contemporary books, the assessments of researchers just as from online media sources. From this exploration, it was discovered that Cryptocurrency or the utilization of virtual money can without a doubt be perceived as a brilliant progressive innovation, but its use as an investment instrument contains elements of maysir (betting) and as a business transaction instrument that contains elements of gharar, it contains tyranny and that including transactions that are prohibited in Islam.Keywords : Enterpreneurship, Cryptocurrency and Islamic Law.
?Cryptocurrency is a blockchain-based technology that is often used as a digital currency. Digital money is different from conventional money, this type of money does not have a physical form but only a block of data bound by a hash as validation. The data is spread to every cryptocurrency user who is in the environment. So that when a user makes a transaction, data mining will be carried out. Cryptocurrencies have several advantages but also have disadvantages when used as currency, from a legal point of view there is still no law governing the circulation of currency in digital form (cryptocurrency). The government must recognize digital currency so that it can be accepted by the general public as a means of payment. For now, the government has not recognized digital money (cryptocurrency) as a currency, because Cryptocurrency is a new phenomenon by some people in Indonesia. The rapid development of technology in the 4.0 revolution era, in the next few years money in physical form will be replaced by digital money seeing the many conveniences provided by using digital money.
The spread of digital technology currently faster and influence on all of human dimension, including to the financial sector. The presence of cryptocurrency using blockchain technology has changed the previously system that has been used for a long period and it come a pros and cons. The system built using peer-to-peer cause the system no longer need the 3rd party that control the financial system and since the system decentralized. The nature of cryptocurrency which made as the same with gold characteristic such as the limitation of quantity, process to get it must through the mining process, more resistance from inflation are making people and society interested and significantly increase time by time. The decentralized and anonymous blockchain working system for token holders and safe has presented as a new paradigm in the financial sector. But on other hand, there are many challenges and dynamics that arise due to the emergence of these cryptocurrency, one of which is risk from the legal perspective where there are cases of money laundering involving of crypto, losses to the investor asset due to ICO process that not run smoothly, the emergence losses from crypto exchanges that hacked due to not have a high security backup system that made the customer losses their digital wallet. Crypto value that tend to have high volatility and fluctuating rates with fast count also increase the risk. The readiness of countries and drafting laws related to the crypto was contribution for this research. One of the biggest interested from the public is the use of crypto as long asset investment, where the values increasing from year to year, even Bitcoin as one of the cryptocurrencies that previously worthless but currently has very fantastic values and become a favourite from the investor

With the growth of the business world, autonomous software programs such as MRP, ERP, and SAP have been used to synchronize different units and departments since the 1960s. There have been great technological developments in the last decades, such as Blockchain, the Internet of Things, artificial intelligence, and machine learning. The attention of the accounting world has also been on those technological developments, especially on Blockchain Technology. Accounting academics and professionals have been trying to understand how blockchain technology can affect accounting and what kind of changes might be brought about by that technology. Therefore, the purpose of this study is to make a systematic literature review in order to foresee the potential effects of blockchain on accounting. Selected keywords were searched for on the Scopus database. The results show that most of the studies in this area focus on technical issues and the development of software applications, and a small number of studies make a connection between blockchain and accounting. Although most of the authors are very optimistic about blockchain technology and claim that this technology may change the double-entry accounting system completely and radically, some have discrete approach and express critical views.
In blockchain technology, all registered information, from the place of production of the product to its point of sale, is recorded as permanent and unchangeable, and no intermediary has the ability to change the data of other members and even the data registered by them without public consensus. In this way, users can trust the accuracy of the data. Blockchain systems have a wide range of applications in the medical and health sectors, from creating an integrated system for recording and tracking patients’ medical records to creating transparency in the drug supply chain and medical supplies. However, implementing blockchain technology in the supply chain has limitations and sometimes has risks. In this study, BWM methods and VIKORSort have been used to classify the risks of implementing blockchain in the drug supply chain. The results show that cyberattacks, double spending, and immutability are very dangerous risks for implementation of blockchain technology in the drug supply chain. Therefore, the risks of blockchain technology implementation in the drug supply chain have been classified based on a literature review and opinions of the experts. The risks of blockchain technology implementation in the supply chain were determined from the literature review.

Pada penelitian ini mengusulkan pembuatan perangkat Internet of Things yaitu smart energy meter dengan menerapkan sistem blockchain sebagai database. Internet of Things memiliki sistem penyimpanan secara terpusat pada database server, jika server down maka database tidak dapat digunakan dan data kemungkinan akan hilang. Terdapat sistem penyimpanan yang memiliki jaringan desentralisasi dan terdistribusi yaitu blockchain. Sistem blockchain pribadi dibuat menggunakan framework Ethereum. Data sensor akan dibaca oleh Raspberry Pi 4B dan dikirimkan ke node 1 melalui MQTT. Node 1 akan menyimpan data ke blok. Dua node akun Ethereum akan memvalidasi blok tersebut. Jika diterima maka blok akan disimpan pada blockchain dan membuat rantai blok baru. Dalam proses penyimpanan memiliki smart contract antar akun Ethereum yang dibuat menggunakan solidity dan diakses menggunakan web3 API. Data yang berhasil disimpan akan ditampilkan ke web pengguna. Berdasarkan hasil pengukuran performa protokol MQTT dan sistem blockchain jika dibandingkan dengan database tradisional, maka blockchain kurang cepat dalam proses penyimpanan karena terdapat proses transaksi dan verifikasi data. Namun jika diterapkan pada data smart energy meter tidak masalah karena waktu yang diperlukan untuk proses penyimpanan maksimal 1 menit saja cukup. Jumlah node dan ukuran data atau blok tidak mempengaruhi kinerja algoritma konsensus proof of authority.

Nowadays, huge amounts of data are generated every second, and a quantity of that data can be defined as sensitive. Blockchain technology has private, secure, transparent and decentralized exchange of data as native. It is adaptable and can be used in a wide range of Internet-based interactive systems in academic and industrial settings. The essential part of programmable distributed ledgers such as Ethereum, Polkadot, Cardano and other Web 3.0 technologies are smart contracts. Smart contracts are programs executed on the global blockchain, the code is public as well as all of the data managed within the transactions, thus creating a system that is reliable and cannot be cheated if designed properly. In this paper, in order to make the educational system more transparent and versatile we will describe an educational learning platform designed as a distributed system.
Elections are a democratic activity in Indonesia which are carried out every five years to elect leaders, but in the process of manual election calculations, the results are leaked and can cause data security problems. Through this research, we can provide solutions by implementing blockchain technology in election applications that will provide security for election results data stored on the blockchain. Blockchain technology is a chain of data blocks that are connected to each other by peer to peer. This application uses the Solidity programming language and uses a local ethereum blockchain database (Ganache). The method used in making this application is the waterfall method with Unified Modeling Language (UML) modeling where the visual modeling method is in object-oriented system design. From the results of testing the blockchain system for this application, it is found that blockchain can help secure election results very securely, where every result data will be stored in every block in a decentralized blockchain network.

Abstract— The technique of following a product or a batch of things throughout the supply chain to ensure that the products that reach clients are authentic and tamper-proof is known as asset tracking. The ultimate goal of an asset monitoring system is to track products along the supply chain, verifying that they haven't been tampered with and, if they have, pinpointing where the tampering took place. Traditional tracking technologies, such as BLE (Bluetooth Low Energy Beacon), which works within a limited range, RFID, and above-mentioned systems, are expensive and centralised. So, for this project, we'll use Blockchain Technology, which is an immutable, tamper-proof, decentralised distributed ledger with security features that allows us to establish an asset tracker that can follow our product along the supply chain. Ethereum is used to implement the system. Unlike other methods, there are no hardware components or large gadgets that may be removed from the original object and attached to the copy. Keywords— Blockchain, Supply Chain, Smart Contract, Keccak-256, Ethereum,GUI

The cryptocurrency market is a market that attracts researchers and investors because it is open every day. This can be seen by the anomalies that occur in the cryptocurrency market. This research uses cryptocurrencies with the largest market cap in 2020, namely Bitcoin, Ethereum, Tether, XRP, and Bitcoin cash as research objects. The data in this study uses daily returns for testing the day of the week effect and daily volatility on the cryptocurrencies under study. This study uses GARCH (1,1) to determine the day of the week effect and daily volatility in the cryptocurrency under study. The results of this study indicate that there is a day of the week effect and daily volatility in the cryptocurrency under study, and it does not move freely. This causes the cryptocurrency market to become an inefficient market. The patterns that occur can be exploited by investors as well as other research on the cryptocurrency under study. Investors can avoid days that have high volatility for example in Bitcoin which experiences high volatility on Fridays and Saturdays because it has a high risk as well. Investors are advised to be able to trade on Thursday for high returns and less risk.
