Technological developments have resulted in a trend of cryptocurrencies that use a technology called blockchain to create and record all transactions made into a digital ledger. Along with the emergence of the trend of cryptocurrencies, this development has also resulted in crimes that hit the digital world, such as data leakage and cyber espionage. This threat can be prevented by applying blockchain technology to the database that has been used. Therefore, we need a system that can facilitate the use of blockchain technology and can process data from an existing relational database into a blockchain-based database. The system developed in this study was built with the FastAPI framework that uses the Python programming language and the React framework that uses the Javascript programming language. This system was tested using Katalon and Wireshark software to perform throughput testing and man-in-the-middle attacks. Evaluation of this system is assessed based on the average throughput time and also the results of Wireshark packet capture. The system designed in this research is expected to help overcome interoperability problems when using blockchain and improve relational database integrity. The results of the test show that the system is safe from man-in-the-middle attacks while sending data through API and has a faster throughput time than BigchainDB system by 4.151 seconds.

<p class="Abstract"><span lang="IN">Massive
 transformation and multifaceted nature of innovation due to increasing
 interconnectivity in globalisation era–particularly through the discourse of
 the Internet of Things (IoT)– have made technology and its instruments nearly
 inevitable in human life, not least in the economic sector. Cryptocurrency as
 one of the products of this activity is getting a great deal of public
 attention. Over time, this currency is gradually favoured by many people around
 the world, especially with the demands for ease of business and transactions in
 the era of digitalisation. The shift allows individuals with access and
 associated resources to store personal assets that cannot be censored/detected
 by central and banking authorities, carry out anonymous financial transactions,
 make high-speed transfers, invest in start-ups, mine new cryptocurrency, and
 even buy land or property in the virtual world/metaverse. All these advantages
 and conveniences encourage individuals, especially businesspersons and
 investors to switch to cryptocurrencies. However, its volatility also incites
 hesitation to adopt it as a medium of exchange/trading transactions. Due to the
 functionality, legality, and disputable implications of its use, this issue
 evokes our interest to study it as a subject matter, especially through the
 lens of axiology. This study employs a qualitative method to generate
 descriptive results. Cryptocurrency serves as a form of digital asset that
 functions as a virtual medium of exchange run in a blockchain system and is
 secured using an automated cipher called cryptography. From an axiological
 point of view, the writer considers at least 5 (five) values constituting
 priority scales in crypto transactions: trust, agreement, utility, pride, and
 speculation. Finally, the writer concludes that cryptocurrency utilisation
 cannot be separated from the axiological perspective of science, considering
 the gap between personal and social values is pertinent.<o:p></o:p></span></p>

Blockchain is an up-and-coming technology designed to ease the process of verifying legitimate products without the need of a centralized system. An example of a well-known technology using Blockchain is Bitcoin and Ethereum cryptocurrency. Blockchain technology will ensure that data residing within each block cannot be tampered with by anyone other than the owner. This paper uses Blockchain technology to develop a system where customers can validate a product legitimacy without the need of a corresponding merchant. This system will be able to be used by manufacturers and companies to ensure that their products will be harder to counterfeit, therefore they will gain more trust from customers. The Ethereum blockchain is used to build the proposed model that is capable of tracing every item's creation and transactions, ensuring the credibility of an item's genuineness. Our simulation results in an effective model and a cost analysis that shows that the model uses an average gas amount of 715,046.3 gwei.
