Payment Channel Network (PCN) is a widely recognized and effective off-chain solution used to reduce on-chain operational costs. PCN is designed to address the scalability challenge and throughput issues in permissionless blockchains. Though transaction throughput is improved, many issues remain, like no flexibility, channel exhaustion, poor sustainability, etc. A separate deposit is required for each payment channel between two users, which locks a substantial amount of coins for a long period of time. Therefore, the flexibility to move these locked coins across channels is impossible through off-chain. Moreover, the channels get exhausted due to unbalanced (unidirectional) transfer. This causes the channel to become unsustainable (dead) until the PCN is rebalanced. This work presents a novel payment protocol called Flexible Payment Channel Networks (FlexiPCN), which allows users to deposit coins per user rather than per channel. So, users can move coins flexibly from one channel to another without the help of the blockchain or setting the cycle off-chain. FlexiPCN has been proven to be secure under the Universal Composability framework.

In the era of global competition, technology has fundamentally lowered the entry threshold for competition. Greater engagement is the real competitive advantage, and gamification design provides uswithways to enhance engagement. Today, gamification interaction methods have gradually penetrated and spread from specific groups of people to the field of ordinary workers. For blind users, the product's humanistic care and satisfaction of emotional needs play a positive role in their confidence and self-esteem. Leverage gamification to help and transform blind people's life participation and experiences. It makes complex behaviors simple and sustainable. This study used a questionnaire survey to explore the relationship between blind somatosensory games and the mental health of blind people.

The idea of the metaverse, a virtual reality-based digital universe, has garnered significant attention due to its potential to revolutionize education and music-related activities. This paper explores the multifaceted relationship between themetaverse, education, and music, shedding light on the opportunities and challenges it presents. Using the PRISMA-ScR method, we proceeded to a sampling of the contributions currently present on the net and extrapolated from search engines such as Eric, Scopus, JSTOR, Google Trends, ACM, Sage Journal, and WorldCat. Based on previously selected indicators, 175 scientific contributions were analyzed, among which those most relevant to the topic were selected based on previously chosen indicators. A clear interest in the relationship between metaverse and music emerges from the contributions, without, however, focusing much attention on the impact these realities can have on the educational process.

With the development of Chinese society and the progress of science and technology, the inheritance and development of the intangible cultural heritage are facing challenges. The topic 'how to protect and inherit the intangible cultural heritage' has become one of the most intense topics in the society. Experience marketing, as a new marketing method in the new economic era, makes the brand better leaving a deep impression in theminds of consumers. Although current Chinese studies have repeatedly conducted research on how to protect the intangible cultural heritage, few studies have further sorted out the connection between the intangible cultural heritage and experiential marketing. Therefore, this paper is to explore the intangible cultural heritage and marketing strategy, to address intangible culture with digital products and experience marketing strategy that could lead to future experience marketing strategy innovation and development with intangible culture and digital product integration in mind. A quantitative research method has been adopted, for which a bibliometric approach via CiteSpace software tool has been employed for analyzing the data obtained with intangible cultural heritage and marketing within China Knowledge Network (CNKI) since October 2010. The results suggest that in the digital marketing of intangible cultural heritage, intangible cultural heritage are better preservation, transformation and dissemination via digital products (games), which has a great significance to the permanent preservation and dissemination of intangible cultural heritage. In the future, with the social attention to intangible culture and through digital for intangible culture, it could provide a good platform for promoting intangible culture, with experience marketing and consumers as the center, creating a unique experience, and making the core connotation of intangible culture, which could become a new research trend in the field of marketing.

Smart contracts are small programs on the blockchain that often handle valuable assets. Vulnerabilities in smart contracts can be costly, as time has shown over and over again. Countermeasures are high in demand and include best practice recommendations as well as tools supporting development, program verification, and postdeployment analysis. Many tools focus on detecting the absence or presence of a subset of the known vulnerabilities, delivering results of varying quality. Most comparative tool evaluations resort to selecting a handful of tools and testing them against each other. In the best case, the evaluation is based on a smallish ground truth. For Ethereum, there are commendable efforts by several author groups to manually classify contracts. However, a comprehensive ground truth is still lacking. In this work, we construct a ground truth based on publicly available benchmark sets for Ethereum smart contracts with manually checked ground truth data. We develop a method to unify these sets. Additionally, we devise strategies for matching entries that pertain to the same contract, such that we can determine overlaps and disagreements between the sets and consolidate the disagreements. Finally, we assess the quality of the included ground truth sets. Our work reduces inconsistencies, redundancies, and incompleteness while increasing the number of data points and their heterogeneity.

This study focuses on the live e-commerce environment, especially in the field of beauty products, and explores how the elements of the live streaming experience affect college students' purchase intention. The college student population has a strong sensitivity to new things and plays a key role in the beauty live streaming market. The mediating roles of perceived value and perceived trust in purchase decision were analyzed using perceived value theory and S-O-R model, and the questionnaire data were analyzed through structural equation modelling (SEM), as well as SPSS and AMOS software, and it was found that the professionalism, popularity, interactivity and attractiveness of the anchors significantly increased the perceived value and trust, and that the transparency and availability of the product information, as well as the scene's atmosphere also had a significant impact on consumers' purchase intention. Transparency and accessibility of product information, as well as a sense of presence in the scene, also had a significant impact on consumers' purchase intention. The results of this study provide empirical evidence on how brands can effectively use live streaming platforms to attract and influence college students, and enrich the theoretical research in the field of e-commerce live streaming.

We describe the Data Protection and Privacy Relationships Model (DAPPREMO), which is based on the set theory and high mathematics, considering that both the data protection and privacy regulation and Ethics principles in those domains belong to a set. DAPPREMO is a new, singular, and innovative solution to adopt a model in data protection and privacy activities. DAPPREMO, through the analysis of reality, allows identifying objects often ignored or unknown. From a data protection and privacy perspective, DAPPREMO reveals itself as an innovative approach to having a broad overview of all the objects related to a specific case or more cases. Moreover, by DAPPREMO, it is possible to identify better the roles of individuals (as data subjects), Institutions (as a controller or processors), and professionals (as Data Protection Officers - DPO or advisors). Thus, we describe DAPPREMO as a solution for a multidisciplinary approach to address any data protection and privacy issue and its future development by applying Machine Learning and Deep Learning to realize a complete artificial intelligence system.

This article focuses on the concept of self-determination and the design and validation of digital tools intended to promote the self-determination of vulnerable people. Self-determination is an essential skill for carrying out daily activities. But in certain situations, and for certain populations, self-determination is lacking, which leads to the inability to live an independent life and in favorable conditions of well-being and health. In recent years, self-determination enhancing technologies have been developed and used to promote independent living among people with self-determination disorders. We will illustrate the main digital tools to support self-determination developed for two populations of people suffering from self-determination disorders: people with an intellectual disability and people with an autism spectrum disorder. The ability of these digital assistants to improve the comfort of life of these people will also be presented and discussed.
