However, current applications within fine arts often involve trivial processes, such as creating digital versions of artworks or replicas of masterpieces as NFT images, and selling only these NFTs. To unlock the full potential of NFTs, more innovative models are needed. This paper introduces a novel model that establishes a permanent link between an NFT and a physical craft object. This linkage is utilized to orchestrate the trade workflow, ensuring a sustained connection between real and digital artifacts. A distinguishing feature is that they can be sold together or seperately and later reunited with a buyer. The NFT serves as a multifunctional certificate, tracing, and communication token.</p><p>Through a comprehensive analysis, this paper explores diverse scenarios that may arise in the relationship between the physical object and its digital twin. It presents a systematic and formal description of the proposed model and its various cases, marking a pioneering effort in the field. Noteworthy advantages include the ability to detect plagiarism and fraud. By strategically incorporating stakeholder roles, the model preserves the anonymity of art collectors while extracting valuable information about the ownership of physical artworks. The primary objective is to enhance security in the art trade and foster new business opportunities for stakeholders. As a proof-of-concept, the model was implemented in a real-world scenario on a leading NFT marketplace platform.</p></div>","PeriodicalId":100376,"journal":{"name":"Digital Business","volume":"4 2","pages":"Article 100079"},"PeriodicalIF":0.0,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666954424000073/pdfft?md5=d07f9c3e0e435b0ad1a50c1a23bee1c0&pid=1-s2.0-S2666954424000073-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141482297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previously the influence of ambidextrous IT governance mechanisms on digital transformation and organizational performance were studied. However, there is a need to investigate what are the key ambidextrous IT governance mechanisms that lead to a successful digital transformation and how they are implemented. A case study was conducted at BRI to address the problem. BRI is an incumbent bank that recently won numerous awards. The case study was chosen to investigate one instance in detail to discover contextual understanding that might not have become apparent priorly. The data was collected by semi-structured interviews triangulated with internal documents until data saturation. Subsequently, the collected data underwent thematic analysis. The findings revealed seven key ambidextrous IT governance mechanisms, encompassing board and executive, strategy and architecture, talent and culture, data and information, development and operation, internal and external collaborations, as well as risk and audit. The study also examined how BRI digital transformation dimensions (digital transformation strategy, strategic alignment, digital and IT assets, knowledge and capability, and innovation culture) impacted organizational performance. Lastly, BRI's organizational performance achievements were examined using operational excellence, customer experience, industry presence, and financial return dimensions. This study offers valuable research insights by exploring the key ambidextrous IT governance mechanisms that influence digital transformation and organizational performance. The study also provides the practical implications on how to implement key ambidextrous mechanisms toward a successful digital transformation, including its organizational performance achievements.</p></div>","PeriodicalId":100376,"journal":{"name":"Digital Business","volume":"4 2","pages":"Article 100083"},"PeriodicalIF":0.0,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666954424000115/pdfft?md5=338901b6db38f27d19ac265bbafae1f0&pid=1-s2.0-S2666954424000115-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141482299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper fills this gap and proposes a blockchain business model framework. The research utilizes a sequential exploratory research design (SERD), encompassing two key phases: an initial phase involving a literature review and interviews to delineate blockchain business model building blocks and types, followed by a subsequent survey to identify the most pertinent building blocks and types. The findings helped to formulate the framework, necessary building blocks, and block types specifically for the blockchain applications. Organizations can tailor their business model through various configuration options and mechanisms, considering the arrangement of block types within each block according to their significant score levels. By giving priority to those with scores above the block's average, organizations can evaluate the performance of their models and pinpoint areas for enhancement. The proposed framework can be considered as a reference point for developing business models for blockchain applications.</p></div>","PeriodicalId":100376,"journal":{"name":"Digital Business","volume":"4 2","pages":"Article 100082"},"PeriodicalIF":0.0,"publicationDate":"2024-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666954424000103/pdfft?md5=872182c43dd1fd3011821c28d6250c69&pid=1-s2.0-S2666954424000103-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141324009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We model nodes group representing actors or wallet addresses, and edges represent transactions between wallet addresses.

We conducted a comprehensive analysis using user purchasing and viewing data for 1541 movies offered by SK Broadband, South Korea's leading VOD service provider. Our analysis employed propensity score matching and difference-in-difference methodologies. The results of our initial analysis reveal that allocating movies to SVOD leads to an 192% increase in the number of views while simultaneously 52% decreasing TVOD sales. Additionally, we investigate the characteristics of movies that are particularly effective for SVOD servicing. To accomplish this, we scrutinized 236 movies available in SK Broadband's SVOD service using a cost-effectiveness analysis. Our second analysis demonstrates that certain categories of movies, including foreign films, non-G-rated movies, animations, and films not allowed as Download-To-Own (DTO), are more suitable for allocation to SVOD libraries. Furthermore, movies with lower box office viewership numbers exhibit greater success when allocated to SVOD.
