https://ecc.journalspub.info/index.php?journal=IJDE&page=article&op=view&path%5B%5D=1871
Nowadays there are lots of new technologies that come and explore different fields. Recently the industry explores blockchain technology-based applications and tries to develop them. Because blockchain provides security without interacting with third parties. So, Trust and Verification are the most important benefits of this technology. Blockchain technology is developing technology but in recent years there has been lots of development happening. And now this technology can transform the industry robustly as it presents new features like e smart contracts, tokenization of content, eliminating counterfeit products, supply chain improvement, digital twins, and end-to- end security. In recent years, blockchain has been used in the financial sector and also to do secure business. One of the risky and need to secure business industries is the diamond industry. The diamond industry is one of the industries where a consumer is the main stakeholder and needs to create trust between two parties. The diamond industry has huge potential to invest a huge amount of money but there are some issues, which hamper the process of the diamond industry like trust and ethics. There is a lot of fraud reporting happening in this field. Traditionally, the document-based record has happened so it is very hard to trace the diamond’s true origin and providence. Also, the consumer asked questions regarding the diamond-like Where did the diamond come from? Was it a blood diamond? Who owns it? Who bought it? Where is it now? Also, the consumer doubts the diamond whether it’s real and what is the market value and all. So, blockchain develops a Trust chain between them to reduce the gap between the diamond industry and consumers. It will also be useful against fraud and property rights. Using Blockchain technology consumers may be confident that the gem they have purchased is legitimate and also property rights as well. So nowadays many supply chains have been developed based on the requirement. So, for consumer utility, blockchain technology proposed diamond authentication and certification. IBM also plans to use blockchain technology to bring trans- parency to the jewelry industry. There is also a big diamond organization like Everledger that has already developed a model using blockchain for the diamond industry. In this paper, we will discuss how blockchain technology revolutionized the diamond industry. Then, we discuss issues of the blockchain industry based on the literature review, suggest the flow of how blockchain is used in the diamond industry, and its countermeasure. And also discuss the challenges.Jagruti BagulBhavyang Dave

https://ecc.journalspub.info/index.php?journal=IJDE&page=article&op=view&path%5B%5D=1836
<p><em>Parking systems is a growing concern, particularly in metropolitan areas where the increase in the number of vehicles has led to road congestion. This study suggests automating the distribution of parking places using internet of things (IoT) technologies to address this problem. The system will provide wireless access to users, allowing them to check the availability of parking areas in real-time. Sensors that can recognise the movement of a car will be installed in each parking space to implement this idea. These sensors will communicate wirelessly with the central server of the system, creating a real-time map of the parking area that shows the availability of parking spots. This will allow users to quickly identify and locate an available parking space, reducing the time and effort required to search for a spot. Overall, this system will be an efficient and smart solution to automate parking management, minimizing waiting times and optimizing the use of parking spaces in metropolitan areas.</em></p>Vikram G.

https://ecc.journalspub.info/index.php?journal=IJDE&page=article&op=view&path%5B%5D=1834
<p><em>Smart contracts have emerged as a powerful tool for automating complex business logic in a decentralized, secure and transparent manner. The Ethereum Virtual Machine (EVM) is a software platform that enables the execution of smart contracts on the Ethereum blockchain. This study article provides an in-depth analysis of the EVM as a smart contract execution engine. We first provide an overview of the EVM, including its architecture, components, and functionalities. We then discuss the advantages and limitations of the EVM, including its scalability and security issues. Due to blockchain immutability, once this code is deployed it cannot be reversed. In this context, formal verification techniques are widely used to check smart contracts’ correctness with respect to a given specification. In light of this, we introduce a model checking-based approach for solidity smart contracts and their blockchain environment using the nuXmv model checker. Our model-<del cite="mailto:stmjournals25" datetime="2023-06-01T14:37"> </del>based approach considers the trans-action pricing mechanism set by the Ethereum proposal EIP-1559 and consists of three main steps, respectively, representing a smart contract with its blockchain behavior into an Extended Finite State Machine (EFSM) meanwhile, providing an over-<del cite="mailto:stmjournals25" datetime="2023-06-01T14:37"> </del>approximation of the contract gas usage following the EIP-1559proposal, then, encoding the modeled EFSM into nuXmv input language and, finally, specifying safety and liveness properties that will be checked against the model. Our contributions reason about modelling and checking gas usage consumption which makes it failure-aware. We illustrate this approach through a voting case study.</em></p>Anchal Arun Jha

2023-07-042023-07-04821017Electronics at Smaller and Smaller Length Scales – Mesoscopic Logic Gates: A Brief Review
https://ecc.journalspub.info/index.php?journal=IJDE&page=article&op=view&path%5B%5D=128
In the present review we inspect two-terminal electron transport through some mesoscopic rings and try to explore how these simple rings can be utilized to design classical logic gates at mesoscale level. Using such rings we can design all possible logic gates like, OR, AND, NOT, NOR, NAND, XOR and XNOR gates, but here we illustrate only three primary logic gate operations for the sake of simplicity. We adopt a tight-binding Hamiltonian to describe the model where a mesoscopic ring is attached to two semi-infinite one-dimensional non-magnetic electrodes. Based on single particle Green’s function formalism all calculations which describe two-terminal conductance and current through the quantum ring are performed numerically. Our analysis may be helpful in fabricating mesoscale logic gates and electronic circuits at smaller length scales.Santanu K. Maiti
