Blockchain Frontier Technology B-Front Journal en-US Thu, 20 Jan 2022 00:00:00 +0000 OJS 60 An Agile Software Engineering Method to Design Blockchain Applications <p><em>Cryptocurrencies and its underlying technology, Blockchain, are transforming banking and economics by allowing trustworthy programs to exist without the requirement for a trusted counterpart. In recent years, the Blockchain and the programs that run on it, known as Smart Contracts, have seen increased use across all businesses that demand trust and verifiable credentials. Some have compared the "Blockchain revolution" to the early days of the Internet and the World Wide Web. As a result, all Blockchain-based software development is accelerating at a dizzying pace. Many software engineers argue that the widespread interest in Blockchain technology has resulted in haphazard and rushed software creation, a type of first-come, first-served competition that fails to assure software quality or take into consideration core software engineering ideas. This research tries to solve this issue by proposing a software development strategy for gathering requirements, assessing them, designing, creating, testing, and deploying Blockchain applications. Several Agile approaches are employed in the process, including User Stories and iterative and incremental development based on them. It does, however, employ more formal notations, such as UML diagrams that define the system's design, with improvements to express unique Blockchain concepts. The method is well discussed, including an example to illustrate how it works.</em></p> Ita Erliyani, siti afifah wulandari Copyright (c) 2022 siti afifah wulandari, Ita Erliyani Tue, 04 Jan 2022 00:00:00 +0000 Benefits Provided by Blockchain Technology in the Field of Education <p><em>The revolution in a technology certainly provides new innovations that are more creative and effective than previous technologies where the technology is called a ledger (blockchain technology).

Because previously blockchain technology was used as crypto or known as digital currency which has developed towards technology and digital is growing rapidly. Where the use of blockchain technology is a new innovation that is increasingly developing in data security systems to suit the times and become one of the modern technologies in the world of education. However, nowadays there are often crimes in the illegal falsification of reviewer letters that can be carried out by irresponsible people for personal interests and can harm the parties concerned. For that we need a data security technology without the need for a third party called blockchain that can maintain the authenticity of the reviewer's letter from the criminal actions of irresponsible parties in forging intentionally or unintentionally. Raharja College has applied blockchain technology to a tool called ABC (data security) and has been implemented on the adimas website which has been going on for two years. Blockchain technology has an encryption hash code or a unique code that is a sign that a letter that has been verified with the blockchain can be seen as different from the original or fake. Because blockchain technology has a level of data security with a block system that is interconnected and has an encryption hash code. This paper uses the literature study method by looking at previous papers with the same theme. This research has the aim that future researchers can produce new innovations in improving data security and improving the quality of technology that can produce new findings in more modern data security systems. </span></em></p> Sindy Amelia, Oktaviana Widya Ningrum Copyright (c) 2022 Sindy Amelia, Oktaviana Widya Ningrum Wed, 05 Jan 2022 00:00:00 +0000 Academic Certificate Fraud Detection System Framework Using Blockchain Technology <p><em><span style="font-weight: 400;">The era of rapid disruption was accompanied by increased crime in data falsification and interception. The philosophy of Blockchain technology is related to its ontology; it can be characterized, applied, and realized by how it works in the world of education. Blockchain technology is used to verify the authenticity of academic degrees and certificates. Systems that use digital signature schemes and implementation timestamps in the development of blockchain technology use blockchain software. The impact of falsifying educational documents results in workers not being qualified for a particular position. The main interest of this service is to balance between graduates and employers by minimizing crime and falsifying educational documents. The method used in this research is a literature study from previous studies. As a result of maximizing the potential of blockchain technology, fees can also lead to checking the authenticity of certificates through trusted sources.

Along with the ongoing digitalization, which brings different problems, issues that often arise regarding the preparation of the current workforce are moving towards further education. In this preparation, pragmatic and hypothetical information can emerge from various containers, mean and channels, whether formal or causal. In addition, it is very difficult to evaluate the level of information skills that students acquire in order to increase their chances of finding jobs in the future. This, along with the need to oversee general education programs, the issue of certainty when approving these files and distinguishing them from original information, and so on, implies that administration in further education needs new, progressive instruments. This work assesses the advantages of blockchain innovation (or delivered notes) and supports a decentralized certainty model for blockchain ubiquitous deployments. In this methodology, blockchain is used to oversee transactions of substance, education and abilities, evaluated with the approval of students, mentors and businesses, to remove for the last time the "gap" between academia and the world of work. This paper intends to address the pervasive, open and ubiquitous current challenges of continuing education. The proposed model can be implemented in any preparatory organization to tailor instructions to the specific needs of an expert profile approved by superiors at the second summit. This model is approved by the method for models with results that more than just acknowledge.</span></em></p> Miftahul Akhyar, Tubagus Muhammad Fadla Yoga, Eva Sukmawati Copyright (c) 2022 Miftahul Akhyar, Tubagus Muhammad Fadla Yoga, Eva Sukmawati Tue, 04 Jan 2022 00:00:00 +0000 Utilization of Blockchain Technology for Future Education <p><em>Blockchain is a distributed ledger that is both decentralized and distributed.

Basically, the medical service area has benefited greatly from blockchain innovations due to safety, security, confidentiality and decentralization. Overall, the Electronic Wellbeing Record (EHR) system addresses issues related to information security, honesty and fairness. In this paper, we talk about how blockchain innovation can be used to change the EHR framework and can be the answer to this problem. We present a system that can be used for the implementation of blockchain innovations in the field of medical services for EHR. The essence of our proposed system is first and foremost to implement blockchain innovations for EHR and in addition to provide secure electronic records capacity by characterizing granular access rules for clients of the proposed structure. Moreover, this structure also speaks to the flexibility issue that blockchain innovation sees as a whole through the use of the off-chain capacity of the record. This structure gives the EHR framework the advantage of having a blockchain-based setup that is versatile, secure, and basic. The information on the blockchain is apparent to everybody that is available on the chain this makes the information weak which is anything but an ideal result for a decentralized stage.</em></p> Sugeng Widada, Warseno, Sugina, Sulthan Taqi Sampoerna Alfian Copyright (c) 2022 Sugeng Widada Widada, Warseno Warseno, Sugina Sugina, Sulthan Taqi Sampoerna Alfian Tue, 04 Jan 2022 00:00:00 +0000 Decentralization Of Information Using Blockchain Technology On Mobile Apps E-Journal <p>Decentralization is the division of centralized power processes as a whole into separate ones.
