As blockchain-based social media platforms continue to gain traction, they hold the potential to reshape the digital landscape and usher in a new era of decentralized, user-centric social networking experiences. 

Given the significance and urgency of this topic, our study aims to analyze the adoption of blockchain technology in social media, focusing on Facebook in Vietnam as a case study. This research will shed light on the potential of blockchain to revolutionize social media, explore the factors influencing its adoption in Vietnam, and emphasize the importance of understanding blockchain technology beyond the sphere of digital currencies.

The research methodology in this paper combines two popular theories in the field of technology: The Technology Acceptance Model (TAM) [8] and the Diffusion of Innovations Theory (DIT). This model aims to understand better the factors influencing blockchain technology adoption in social networks, particularly Facebook in Vietnam. The model analyzes three levels: state, group and individual.

At the state level, the research model examines the role of the regulatory environment and technical infrastructure derived from DIT in shaping the adoption of blockchain technology in social networks. The regulatory environment assesses the impact of government policies and regulations on the diffusion of blockchain technology, while the infrastructure factor evaluates the availability and quality of technological resources needed to support the technology's adoption in the social networking industry. 

At the group level, the analysis focuses on TAM's social influence and DIT's industry competitiveness as the critical determinants in adopting blockchain technology in social networks [9]. Social influence measures the impact of friends, professional networks and opinion leaders on individuals' and organizations' decisions to adopt blockchain technology [8]. Industry competitiveness examines how market competition affects social networking companies' motivations to integrate blockchain technology into their platforms. 

At the individual level, the research model incorporates four factors from TAM: perceived usefulness, perceived ease of use, attitude toward using blockchain technology and behavioral intention to use blockchain technology. Perceived usefulness assesses users' trust in the benefits of applying blockchain technology in social networks, while perceived ease of use evaluates their perception of the technology's complexity and user-friendliness. Attitude toward using blockchain technology encompasses users' overall viewpoints on applying and using the technology on social networking platforms.

The research model was developed based on feedback from 250 participants in Vietnam, with a diverse representation at the individual, group and state levels. Through an online survey, data was collected and analyzed using the Partial Least Squares (PLS) method to evaluate the relationships between different factors within the model and identify the critical drivers for adopting blockchain technology in social networks in Vietnam. The findings highlight significant factors at each level of analysis. At the state level, the regulatory environment and technical infrastructure were found to impact the adoption of blockchain technology positively. Social influence and industry competitiveness were influential factors at the group level. Finally, at the individual level, perceived usefulness and ease of use emerged as the most crucial factors shaping users' attitudes and intentions toward utilizing blockchain technology on social networking platforms. 

By combining TAM and DIT, this research model provides a comprehensive view of the essential factors for adopting blockchain technology in social networks in Vietnam. The research findings can assist social network operators, technology developers and governments in directing and promote blockchain technology's effective adoption and application in social networks.

Findings

Overview of Blockchain Technology and Social Media: Blockchain is a groundbreaking technology that operates as a distributed, decentralized and immutable ledger for securely and transparently recording transactions and data. Functionally, blockchain can be conceptualized as a distributed digital ledger, with each block in the chain containing a record of valid network activity since the last block was added. As Bernard Marr described, blockchain employs a distributed database that organizes data into blocks with cryptographic authentication, timestamping and encryption. The blocks are then linked in a chain, making it exceedingly difficult for anyone to tamper with the data without possessing the encryption key.
