South Asia countries like Bangladesh, India, and
Pakistan have a large number of fuel filling stations that use
centralized payment transaction systems. In some cases, this fuel
filling station uses the hand cash payment system which is not
secured and time-consuming. Each transaction takes more than
five minutes to process. For that reason, in some cases, customers
face the huge hassle of standing in a long line and waiting for their
turn. Not only that, there are high possibilities of fraud activities
and robbery being occur for large amounts of the payment
transaction. To solve this problem we propose a blockchain-based
payment transaction method for fuel filling stations. Here we use
the decentralized open ledger infrastructure and proof-of-work to
approve each transaction block. Every transaction between the
customer and the filling station authority is completed through a
digital wallet which is fully secured, fast, and transparent.
Comparing to the bank payment transaction system our proposed
method is decentralized and has low transaction fees applied in
every transaction. This transaction process is free from thirdparty involvement and all transactions are immutable. For that
reason no issues of customer trust and safe from fraud activities in a large number of payment transactions. Our proposed payment transaction method can play an important part to handle large amounts of transactions and provide transaction security for
increasing the number of fuel filling stations in South Asia's most
populated country.

As the world became more digitalized thanks to the Internet, it led to the creation of Electronic Payment Systems that are now used to seeing all over the world, but there is a need for estimation the return on development and implementation of EPSs. The research goal is to develop an approach based on optimization modeling for the assessment of the efficiency of implementation and the use of electronic payment systems by Ukrainian and international businesses for their day-by-day operations. The article also analyzed different classifications of EPS and determined several types of methodology for the evaluation of the effectiveness of the EPS (absolute and relative to business results and costs). Using the optimization model and system analysis, the authors proposed the algorithm for the estimation of profit from EPS implementation (both separate EPS or portfolio of EPSs) and make an experiment for one of the EPS for the period of 2023-2026. The optimization model includes revenue from EPS, as well as salary, rent, and infrastructure costs, which helps to improve the results of EPS implementation by adapting of transaction’s tariff. Authors also described the process of solving optimization task for determining effective tariff per 1 transaction, taking into account marketing information.

In Web 2.0-based social networks, users suffer from authorities of service providers and politicians, such as revoking users, removing content, and selling users’ sensitive information. The concept of decentralized finance (DeFi) as a blockchain-based technology is one of the most popular achievements of blockchain, involving digital assets, smart contracts, protocols, and applications. In the present study, a new subgroup of DeFi is identified known as social finance (SocialFi). It states that social media components can be presented as blockchain-based tokens and SocialFi can be a solution to the definite problems of centralized social media. Therefore, this study addresses the related technologies of SocialFi (e.g., peer-to-peer networks, Web 3.0, decentralized autonomous organizations, and Metaverse) and describes the challenges and opportunities of the next generation of social media. Some main SocialFi challenges reviewed in this study are scalability, regulation, and fake news detection/prevention. Finally, the future direction of this new field in social and computer sciences is discussed.

Privacy and transparency in vote counting are the most prevalent concerns these days due to the involvement of untrusted authorities in the counting process. As a result, the counting process faces significant privacy, trust, and transparency hurdles. Hence, there is a need for an efficient and trusted mechanism to resolve such problems. Blockchain technology has the potential to bring transparency and trust in several applications. Therefore, in this work, we explore blockchain technology in conjunction with a secure partitioning scheme to promote transparency, trust, and privacy between users and participating authorities in a decentralized platform. This paper presents a chaincode-based implementation of our proposed secure and verifiable vote counting mechanism that enables trust and fairness over a decentralized platform. Multiple authorities participate in the vote counting process in a trusted manner to cooperate and coordinate in a decision process over a decentralized platform. Our research exhibits that blockchain technology can eliminate the trust gaps and increase transparency and fairness in the election and vote counting procedure. We register user votes in the blockchain platform based on the secret sharing mechanism to enable fairness and openness between counting authorities. Each vote is recorded into the distributed ledger to support openness and verifiability in our mechanism. The ledger is accessible to every registered user as per the permissioned blockchain policy. We created many authorities in the blockchain network and deployed multiple smart contracts on the Hyperledger platform to analyze the feasibility of our strategy. The performance results are obtained and reported using the Hyperledger Caliper benchmark tool. The results demonstrate that the proposed chaincode-based solution achieves the highest throughput at 200–400 tps for fetching and removing contracts. We achieve the optimal latency of 18.09 s for the vote distribution contract and up to 4.57 s for the counting contract.

“Internet-of-Things (IoT)” systems and components are highly noticed by cybercriminals including the affiliated or the nation-state sponsored threat actors as become a united part of the linked ecosystem and the society. But, the difficulties in protecting the systems and the devices are combined of scale and multiple deployments, the speed-paced cyber threats landscape, and more parameters. With the enhanced internet services, cyber security grows one of the highest research issues of the latest digital world. It is very important to develop a cyber security model to identify the various types of attacks. To overcome these problems, a quantum-inspired blockchain-assisted cyber security model is obtained in the IoT platform. Firstly, the required information is obtained from quality online information resources. Then, the information is stored in the quantum-inspired blockchain with optimal key, where the key optimization is performed with the help of the Fitness-based Jellyfish Chameleon Swarm Algorithm (FJCSA). Then, the stored data are recovered and finally, fed to the intrusion detection stage to verify whether it is affected by any unauthorized entities. The intrusion detection is done with the support of “Adaptive Attention-based Long Short Term Memory (LSTM) with Adaboost (AALSTM-Ab)”, where the parameters are optimized by using the FJCSA. Furthermore, the experimental results of the developed model are validated by comparing the performance of various recently implemented blockchain-based cyber security approaches with respect to several positive and negative performance measures. From the result analysis, the accuracy and precision rate of the recommended model are 95.50% and 91.40%.
The conflict between climate change and energy scarcity has recently gained widespread attention. The development and promotion of green power and renewable energy is an efficient strategy to address this issue. The widespread use of distributed renewable energy in microgrids results in decentralized power supply. The features of distributed power trading, such as low single transaction volume and frequent transaction intervals, present both possibilities and problems to the green electricity market. The usual centralized control and selling of power are no longer appropriate in this circumstance. This study proposes a decentralized energy transaction system architecture in the microgrid and connects the double auction mechanism to achieve the interests of each participant based on blockchain technology and the status quo green power trade in China. Finally, using the trading strategy and model, this study constructs a real and operational energy trading platform, and simulated experiments demonstrate the dependability and efficacy of the proposed trading mechanism.
