What is blockchain technology?since its invention in 2008. The first decentralized by Satoshi Nakamoto. He improved the overall design using a Hashcash like method. The design was implemented as a core component of the cryptocurrency bitcoin where its serves as the public ledger for all transaction on the entire network. It is a digital ledger technology that allows for secure and transparent record-keeping of transactions.In a blockchain, every participant has a copy of the ledger, and all transactions are verified and recorded in a decentralized and transparent manner. The security of the blockchain comes from the fact that once a block is added to the chain, it cannot be altered or deleted without the consensus of the network.Besides its original use case in digital currencies, blockchain technol- ogy has been applied to various industries, such as supply chain management, healthcare, real estate, and voting systems. Its po- tential benefits include increased security, transparency, effi- ciency, and decentralization. One of the key benefits of using blockchain technology in voting is the ability to create a trans- parent and decentralized system. This means that anyone can verify the accuracy of the results, and there is no need for a centralized authority to oversee the process. The blockchain acts as a distributed ledger, with each node on the network hold- ing a copy of the transaction history. Key Words: Blockchain, Voting
Blockchain is a digital ledger of transactions that is duplicated and spread over the whole network of computer systems on the blockchain, and it is a system of preserving information in a way that makes it difficult or impossible to edit or hack. Collecting, identifying, evaluating, analyzing, preserving, and presenting evidence is a difficult task in existing forensics. That's where the blockchain'sdecentralized nature comes into play, with forensic data being stored in the private network using the blockchain's nodes in a peer-to-peer network. Digitalforensics will also be more secure,and the investigation will be more transparent to those on the other side of the jurisdictional border. In the criminal investigation process, information that frequently changes is stored in the hotblockchain, and unchanging data such as videos are stored in the cold blockchain. In this we are using the Ethereum concepts and implementing smart contracts. Keywords - ledger, chain of custody, Hyperledger fabric, forensic.

There are a lot of things that humans cannot do, and one of them is being fair, especially when he is running a casino. However, Ethereum can. Constructing a casino that is regulated by Ethereum can give us the first fair casino in the world. With the help of some technics of cryptography, which are public/secret key schemes and one-way functions, the secrecy and privacy in the gambling of each player can be ensured while still making the game fair by the blockchain. During the construction, Ethereum is also found to be fit for the casino’s other aspects such as propaganda and payment. By successfully constructing such a casino, a way of converting the fixity of blockchain into fairness is proposed in the area that needs it and lacks it the most, which is a casino. Following down this road, any area that lacks fairness can exploit Ethereum or block-chain to find a way to achieve fairness.

Abstract: Mata uang kripto, seperti Bitcoin telah memicu diskusi yang intens. Meskipun mendapat perhatian publik yang luas, pemahaman teoritis terhadap nilai mata uang digital berbasis blockchain masih sangat terbatas, misalnya dalam menentukan besaran tukaran bitcoin terhadap mata uang konvensional yang sangat sulit. Penelitian ini berbasis teori mengenai penentuan nilai tukar Bitcoin (terhadap USD), dengan mempertimbangkan faktor teknologi dan ekonomi. sejak awal tahun 2013 karena fluktuasi harganya yang sangat besar. Penelitian ini menguji pengaruh nilai tukar (USD/ AUD, USD/ EUR, USD/ GBP, dan USD/ JPY) terhadap imbal hasil bitcoin yang mencakup periode 2018 hingga 2022 melalui data sekunder berupa closing price bulanan dari tahun 2018 – 2022. Data yang diambil menggunakan data bulanan selama periode 2018-2022. Teknik analisis data menggunakan data deret waktu dengan bantuan Eviews 10 dan metode model uji Autoregressive Distributed Lag (ARDL) untuk menganalisis pengaruh variabel independen terhadap variabel dependen. Hasil penelitian menunjukkan bahwa return Bitcoin terpengaruh secara signifikan dari nilai mata uang USD/JPYdan tidak terpengaruh secara signifikan dari nilai mata uang asing (USD/ EUR, USD/GBP, USD/ AUD dan USD/ IDR). Hal ini mungkin sebagian disebabkan oleh faktor umum yang mempengaruhi pengembalian USD/JPY dan Bitcoin secara bersamaan dalam beberapa waktu terakhir. Pihak- pihak yang tertarik dapat fokus untuk menyelidiki pengaruh nilai tukar terhadap mata uang kripto dengan mengambil beberapa mata uang digital, tidak hanya bitcoin.
As blockchain technology continues to gain attention, there is a growing need to make it more accessible to young learners in K-12 education. However, the technical complexity and lack of accessible tools have been identified as significant barriers to adoption. Our paper proposes a new method for empowering NFTs by continuously updating their metadata using an API layer. The approach aims to reduce the barriers to entry and enable K-12 students to explore blockchain technology in the same way they learn computational thinking through visual programming tools like Scratch. Our method utilizes Google Blockly, a visual programming language, to make updating NFT metadata more accessible and engaging for young learners. By leveraging a familiar and engaging visual programming language, students can develop their computational thinking skills and explore blockchain technology in a fun and intuitive way. The paper discusses the benefits of using NFTs as a learning tool, including how they can help students understand the concept of digital ownership and value. Overall, our proposed method has the potential to promote student engagement and understanding of blockchain technology, which could have significant implications for the future of education.

Smart destinations require a management system that provides convenient real-time use of digital technology in creating, communicating, and delivering value to visitors. Research related to smart island destinations is still limited, let alone those that utilize blockchain technology to create the smartness of the destination. This research is an empirical study that captures the perceptions of stakeholders in the blue economy on smart islands and the use of blockchain technology in order to build smart islands, a destination that consists of many islands that lack connectedness, such as the Seribu Islands in Jakarta, Indonesia. Data were collected using qualitative and quantitative approaches (mixed methods). Qualitative data were collected from scientific journal publications and followed up with VOS viewer analysis, and quantitative data with the questionnaire survey responses from 150 blue economy industry players in the Seribu Islands and structural equation modeling showed that good digital literacy and blue economy management have significant influence on blockchain technology and impact smart islands. This study indicates that, for islands that have challenges in accessibility and connectivity, the presence of blockchain and smart technology is needed to integrate various resources from each stakeholder so that the blue economy in the islands can be developed more effectively and efficiently, while at the same time ensuring the achievement of sustainability.
Blockchain is a peer-to-peer distributed ledger technology, nowadays widely used and a hot topic in the industries. A Smart Contract is a virtual contract based on Blockchain technology which executes and operates between two parties (especially a buyer and a dealer) when a certain condition of the contract is met. The objective of this research is to present a decentralized transaction system based on Blockchain technology implemented using Smart Contract. Blockchain based cryptocurrencies are an evidence for a secure implementation of any currency-based centralized systems put forth in use in a decentralized way. Current transaction systems and payment gateways are centralized systems that need monitoring and verification from a central agency like a bank or a third party organization which are not completely automated as some of the processes are human controlled. Also deposition and withdrawal of money sometimes take a long procedural time. Still these systems are neither completely error free nor secure and time to time certain issues may arise. Even nowadays some payment methods charges transaction fee which is like paying for the money you are paying for. In this research paper we are proposing an automated Ethereum blockchain technology based transactionsystem which will eliminate the bank and third party verification.Each block of the Ethereum blockchain in the system will store the transaction details also linked with all the previous transaction details in the form of a chain. A Smart Contract is used to define the terms and conditions of the transaction which include account creation, ether deposition and withdrawal. This system enables users to carry out transaction without any fraud and losses from anywhere around the globe within split seconds. Keywords: Transaction system ,Blockchain, Smart Contract, decentralized,crypto-currency

Blockchain is a digital ledger technology in which transactions are stored in a continuously growing list of blocks that cannot be changed and distributed without a centralized server. In recent years, the airport industry has become one of the industries that have implemented blockchain into its business processes. For this reason, we would like to review existing research on the implementation of blockchain in the airport industry to provide an overview of how far blockchain has developed in the industry and also to identify which business processes in the airport industry can be optimized by implementing Blockchain. The review results show that there are three business processes that take place in airports, namely baggage handling systems, cargo handling, and passenger management for aircraft. Blockchain Technology can also be combined with other supporting technology, such as IoT, Artificial Intelligence (AI) / Machine Learning (ML), Big Data, etc. From the research literature that we analyzed, the combined use of blockchain technology with IoT and AI/ML can increase security in the process of data transactions in the system.
Mencapai keseimbangan antara skalabilitas, keberlanjutan, dan keamanan sambil mempertahankan desentralisasi telah menjadi solusi target untuk aplikasi blockchain yang terdesentralisasi selama beberapa tahun terakhir. Beberapa pendekatan telah diusulkan oleh beberapa tim blockchain untuk mencapainya, Ethereum termasuk di antaranya. Ethereum berada di jalur peningkatan protokol utama yang disebut Ethereum 2.0 (Eth2), menerapkan Sharding dan memperkenalkan Proof-of-Stake (PoS). Karena perubahan mekanisme konsensus merupakan masalah yang rumit, peningkatan ini akan dicapai melalui fase yang berbeda, yang pertama adalah penerapan Beacon Chain. Sebagai Ethereum1, Eth2 mengandalkan jaringan peer-to-peer (p2p) terdesentralisasi untuk distribusi pesan. Hingga saat ini, ada lebih dari 17.500 node di jaringan utama Eth2 yang tersebar secara geografis. Namun, topologi yang satu ini masih belum diketahui. Dalam makalah ini, kami menyajikan hasil yang diperoleh dari analisis yang kami lakukan pada jaringan p2p Eth2. Menggambarkan topologi jaringan, kemungkinan bahaya yang disiratkan oleh yang satu ini (Cortes-Goicoechea and Bautista-Gomez, 2021).
It is crucial to use blockchain to notarization system. Although a notarized will has the highest legal effect, the notarization process is cumbersome, the notary agency has heavy responsibilities and high costs, which has become a drawback of notarized wills, and which makes many people give up notarized wills. This research will design a will notarization system based on blockchain technology to solve the problem of difficult will notarization. Through demand analysis and scenario analysis, this paper builds the overall architecture of the will notarization system based on blockchain technology and the Ethereum platform. The architecture consists of three parts: the client used by the user, the server provided by the notary office, and the blockchain module. Based on the Truffle framework provided by Ethereum, it will involve multiple links such as HTML front-end development, JavaScript development, solidity smart contract development, Ethereum interface call, network construction, etc., to design the entire system deployment and operation process.
