Abstract
Throughout the 2010s, blockchain was widely embraced for improving data storage efficiency and transparency. However, it later hit a trough of disillusionment, criticized for overhyping its benefits and setting unrealistic expectations. Grounded in qualitative research design and methods, this research explores technology affordances and constraints of blockchain for curbing public sector corruption, especially in countries plagued by systemic corruption, using Thailand as a primary context. The findings indicate that blockchain’s Distributed Ledger Technology (DLT) effectively mitigates the principal–agent problem by enhancing both vertical and horizontal transparency. However, the adoption of blockchain is hindered by several constraints, including potential misuse, cost-efficiency, regulatory governance, security and confidentiality, and digital skills and organizational culture. Therefore, introducing blockchain into government operations must not occur in isolation; it requires a holistic integration of sociopolitical and economic factors to ensure that it serves as a viable anticorruption tool.
Introduction
Over the past two decades, the use of Information and Communication Technology (ICT) with a view to promoting transparency in public administration has been one of the most accepted approaches for anticorruption (Bertot et al., 2010; Shenkoya, 2023). The arrival of blockchain in 2008 (see further Nakamoto, 2008) and its subsequent success in finance inspired many governments around the world to explore the potential application of blockchain to maximize transparency of government transactions and records, thereby mitigating public sector corruption (Tan et al., 2022).
Blockchain, with the assistance of a computer algorithm, is a digital technology discharging the essential function of recording and storing data and transaction histories in a digital format. Unlike earlier e-service technologies, blockchain utilizes a decentralized system known as Distributed Ledger Technology (DLT) to empower network stakeholders (i.e., nodes) to visualize and verify every record, which obviates the need for a central entity or intermediary, such as a central bank, to approve transactions. By eliminating third-party intermediaries, blockchain’s distributed architecture improves the transparency, integrity, and auditability of data (Frolov, 2020). Suppose a country implements a public blockchain for income tax collection. In this scenario, the network is permissionless and accessible to any taxpayer with an internet connection, enabling them to independently verify network information and validate new data. 1
The adoption of blockchain in government rose to prominence throughout the 2010s (Fan et al., 2024), driven by claims that the technology offers greater efficiency and transparency than traditional bureaucratic oversight, especially for trust-related challenges in finance and government (Baquero, 2023; Meyers and Keymolen, 2025). However, this adoption has entered a phase of disillusionment in recent years as a number of studies on the technology (e.g., Cagigas et al., 2021; Tan et al., 2022) have highlighted not only technology affordances of blockchain in government but also the constraints associated with the application of such technology, including the insufficiency of well-trained civil servants, high capital investment in blockchain infrastructure, and regulatory uncertainty. The portrayal of blockchain as “the problem-solving” technology was critiqued as a mere marketing hype advertised by techno-solutionists (Baquero, 2023; Cagigas et al., 2023; Meyers and Keymolen, 2025; Sætra and Selinger, 2024).
To date, there is little empirical evidence yielding insights about the actual use of blockchain technology as well as the firsthand experience of the people involved with the application of blockchain in government, especially in the context of developing countries where corruption is deep-seated. In Thailand, a country that has long been exacerbated by cultural and political milieu of patronage and money politics, blockchain technology has recently been adopted in some government agencies, spearheaded by a technocrat-turned-minister (Prateeppornnarong, 2023). Although blockchain technology is mainly used to enhance public service delivery in the country, it begs the question of whether the application of such technology helps in curbing corruption in the Thai public sector. This research aims to address the aforesaid question, contributing a new empirical case to the existing literature on blockchain in government.
In line with the research question, the primary objectives of this research are threefold: to examine the key features of blockchain technology relevant to enhancing transparency and curbing corruption; to identify technology affordances and constraints of blockchain adoption for fighting public sector corruption; and to broadly explore how Thailand should approach the use of blockchain with a view to combating corruption in the public sector.
Literature review
Principal–agent theory
In corruption scholarship, the principal–agent theory is arguably the dominant framework for explaining why corrupt practices occur. Fundamentally, the theory attributes corruption to information asymmetry between the principals and the agents (Persson et al., 2013), illustrating how such disparities enable agents to pursue their self-interest based on rational-choice logic (Andersson and Bergman, 2008; Martinsson, 2021). At the bureaucratic level, the principals could be the leadership of a government or of a government department while officers of lower rank are the agents. At the societal level, members of the public are conceptualized as the principals, and public officials are the agents (Marquette and Peiffer, 2018).
According to the theory, principals delegate authority to agents to act in their interest. However, the principal–agent problem emerges when agents possess private information about a task. If an agent rationally calculates that the benefits of withholding this information outweigh the risks of detection, information asymmetry occurs. This prevents the principal from enforcing accountability, allowing the agent to diverge from the delegated mandate to pursue their own interests (Persson et al., 2013). For instance, public procurement officers gain in-depth market knowledge about supplies through routine interactions with vendors. If they perceive the risk of detection to be low, they may choose to abuse their position to extract rents. Senior executives, hindered by this information asymmetry, are unable to perfectly monitor their subordinates’ performance.
The prominence of principal–agent theory in recent decades gave rise to numerous institutional reforms, especially in developing countries. Most of these directed resources toward setting up accountability mechanisms (e.g., independent watchdog bodies, independent media, and conflict-of-interest regulations), whereas others aimed at promoting transparency in public administration through the adoption of ICTs. These reforms were specifically targeted at making corruption a high-risk and low-return business, thereby minimizing the opportunities and incentives for public officials (Prateeppornnarong, 2023).
The concept of transparency
By and large, transparency can be defined as “lifting the veil of secrecy” (Davis, 1998: 121) or “openness, clarity, or the capacity to be seen through” (Tamronglak, 2023: 117). Heald (2006) classifies transparency into two types and four directions based on the flow of information within an organization. The first type, vertical transparency, encompasses both upward and downward flows. Transparency upward involves hierarchical supervision where superiors (principals) monitor the conduct of subordinates (agents); a lack of such transparency often results in principal–agent problems. Conversely, transparency downward allows subordinates to observe the behavior of their superiors. The second type, horizontal transparency, consists of outward and inward flows. Transparency outwards enables organizational members to observe and learn from the external environment, whereas transparency inwards allows external actors to scrutinize the organization.
In modern societies and bureaucracies, ICT-mediated transparency, referred to as leveraging technology to see clearly through the window of an institution, is a popular approach for ensuring government efficiency and accountability (Meijer, 2009). Proponents argue that this form of transparency improves performance among public officials and serves as a deterrent against corruption. In addition, it provides the public with better information, thereby promoting the rationalization of society (Meijer, 2009). In contrast, critics argue that ICT-mediated transparency is unidirectional, structured, and decontextualized. O’Neill (2002) warned that this can erode societal trust and lead to the manipulation of truth, as officials – aware that their actions will be made public – may alter their behavior or records to appear favorable.
Despite inherent trade-offs, using technology to enhance transparency is, overall, a positive development. Furthermore, the adoption of ICT-mediated transparency is arguably essential for anticorruption efforts. First, the use of ICT heightens transparency in the public sector, promoting an open culture that serves the citizenry. Second, it empowers the people’s right to know, allowing them to scrutinize whether officials are discharging their duties properly and with integrity. Third, while some argue that ICT-mediated transparency erodes societal trust in governmental institutions, considering from a different angle, it can actually bolster the government’s reputation for being clean and honest. Finally, fears about distorted facts or security leaks can be managed by making sure that disclosed information serves public interest, and such disclosure will not jeopardize security and confidentiality (Tamronglak, 2023).
Blockchain solutionism: Affordances and constraints of blockchain
As noted, blockchain received significant attention in its early stages, but was subsequently viewed as overhyped – regarded merely as an attempt by techno-solutionists pushing for its adoption to solve “virtually non-existent problems” (Frederik, 2018 cited in Meyers and Keymolen, 2025: 789). In addition, utilizing ICT to foster transparency brings both benefits and challenges. Consequently, this research engages with the critiques of blockchain through the lens of techno-solutionism as well as technology affordances and constraints theory.
Techno-solutionism: A brief discussion of the concept: Prior to addressing techno-solutionism, it is essential to understand the concept of “solutionism.” As Sætra and Selinger explained, Solutionism is a way of thinking about social problems. It is characterized by confidence in human reason and our capacity to find and implement numerous strategies for overcoming obstacles and capitalizing on opportunities, typically through courses of action that significantly alter social norms. (Sætra and Selinger, 2024: 12)
Coined by Morozov (2013), the term “technological solutionism,” or “techno-solutionism,” is an extension of the concept of “solutionism.” In essence, techno-solutionism assumes technologies or technology-driven approaches as the solution to social problems, reflecting the extent to which the arrival of new technology drives hopes and expectations for fixing existing problems (Meyers and Keymolen, 2025).
The primary critique of techno-solutionism is that applying technology to address complex social issues, such as corruption, is overly simplistic. It results in an excessive reduction of complexity, rendering the proposed solutions ineffective or inappropriate (Meyers and Keymolen, 2025). Sætra and Selinger raised a fundamental question in relation to the aforementioned critique: “Is technology being used to address social problems without requiring people to make significant behavioral changes?” (Sætra and Selinger, 2024: 13). Undoubtedly, the application of blockchain in government to solve public sector insufficiencies and transparency issues has been subject to similar criticism. By examining the adoption of blockchain in government through the lens of techno-solutionism, this research characterizes “blockchain solutionism” as an idealistic notion that blockchain technology serves as a solution to intricate sociopolitical and economic issues.
Blockchain solutionism depoliticizes social problems by treating corruption as a data error rather than a structural issue. It envisions a future where cryptographic consensus automates transparency, making corruption vanish from public administration. The next point concerns trust. Since it is usually claimed that data on a blockchain are immutable (see details in the next subsection), data integrity is high. Nevertheless, there is no guarantee that the data are truly authentic before it enters the blockchain system. Finally, critics argue that techno-solutionists tend to promote technology (in this case, blockchain) as a solution in search of a problem. This approach tries to shoehorn technology into a situation, rather than diagnosing the problem first and then designing a solution. Essentially, this gets the process back-to-front (Baquero, 2023; Hung, 2024; Meyers and Keymolen, 2025; Morozov, 2013; Sætra and Selinger, 2024).
Technology affordances and constraints theory: Aligning quite well with the tenets of techno-solutionism, technology affordances and constraints theory aims to present and describe the aspects of technology adoption in the context of social advancement. To grasp the material and sociopolitical dimensions of ICT, one must look to its affordances and constraints; doing so provides, as Majchrzak et al. (2016: 272) argued, an explanation for “how and why the ‘same’ is used or has different outcomes in different contexts.” Inspired by psychologist James Gibson’s concept of “affordance,” Majchrzak and Markus (2013) have propounded technology affordances and constraints theory to study the interactions between people, organizations, and ICT and to identify how people perceive utilities of a particular ICT as well as the consequences of such technology. Technology affordance refers to “potential action that individuals or organizations could do with a specific technology” while technology constraint focuses on “the way(s) in which the given actor is hindered from reaching a specific goal when using the selected technology” (Maragno et al., 2023: 3).
As for blockchain technology, the process begins when a transaction is requested. A block representing this transaction is created and broadcast to a peer-to-peer network of nodes. These nodes validate the block using a consensus mechanism, such as Proof of Work (PoW). Once the network confirms the legitimacy of the transaction, the block is added to the existing chain. Each new block includes a hash – a deterministic hexadecimal number – of the previous block. This links them together securely, forming the structure known as a “blockchain” (Ølnes et al., 2017).

How blockchain works.
As highlighted in the “Introduction,” DLT facilitates the peer-to-peer confirmation and approval of transactions, bypassing traditional intermediaries. This mechanism underscores transparency of data storage – the visibility of data on a blockchain network by stakeholders – as one of the technology affordances of blockchain; the distributed architecture ensures that every node can monitor transaction requests, while the collective validation process ensures that recording remains verifiable. Furthermore, the integration of cryptographic proofs (e.g., Proof of Work) and hashing functions provides transactional immutability – the inability to change or delete data once it has been written to the blockchain, safeguarding data against tampering. Theoretically, this transparency can mitigate information asymmetry within the principal–agent framework. Likewise, the immutability affordance reduces opportunities for bureaucratic opportunism, often fueled by informational uncertainty and asset specificity, by decentralizing data governance. Taken together, these affordances enhance auditability – the ability to monitor a blockchain system and track changes to data over time, allowing stakeholders to verify the provenance and historical integrity of all recorded transactions. All of these affordances, in turn, contribute to effectiveness of anticorruption.

The linkage between DLT in blockchain and the solving of corrupt practices.
Blockchain technology is generally classified into four main types: public, private, hybrid, and consortium. A public blockchain is permissionless, making it accessible to anyone wishing to execute a transaction. In contrast, a private blockchain is controlled by a single entity with restricted access; users require permission from a network administrator to join. The hybrid blockchain combines elements of both public and private chains to address their respective limitations. Typically, this model uses a public consensus mechanism for verification, while storing transaction data privately – accessible only to permitted users. Finally, a consortium blockchain is a permissioned network governed by multiple organizations (stakeholders), such as a banking community, rather than a single entity.
The following is a discussion of the technology affordances and constraints of blockchain, based on empirical evidence from available public sector use cases; noting that, until now, research specifically detailing the implementation of blockchain and its consequences for anti-corruption remains scarce.
One public service area plagued by corruption is land administration. Fraudulent transactions are largely due to a lack of transparency in processing, particularly the inaccessibility of credible land records. This opacity fosters opportunistic behavior and exacerbates the principal–agent problem (Kshetri, 2022). For instance, unaware landowners (the principals) can be exploited by corrupt officials (the agents) who take advantage of opaque land titling systems. In this context, blockchain can help principals monitor agents effectively; its immutable transaction histories and accessibility empower landowners to safeguard their property rights. Georgia presents a compelling case for the practical application of blockchain in land titling. The country conducted a trial in 2016 with remarkable results. By 2018, 1.5 million land titles were successfully published on the blockchain, restoring public confidence in national agencies (Shang and Price, 2019). Notably, this example highlights how DLT enhances both vertical and horizontal transparency.
As exemplified in the principal–agent theory subsection, public procurement is another aspect of the public sector that is particularly prone to corruption. Public sector corruption remains a pervasive issue in Latin America, particularly within procurement systems. A prime example occurred in Colombia regarding the School Meal Program (Programa de Alimentación Escolar: PAE). A 2017 investigation revealed that contractors purchased food intended for vulnerable children at four times the market price. This revelation came on the heels of a 2016 report showing that 32 million meals had gone undelivered. A recent collaboration between the World Economic Forum (WEF), the Inter-American Development Bank (IDB), and the Office of the Inspector General of Colombia has brought about the application of blockchain technology to tackle these challenges. The project increased real-time transaction visibility and decentralized authority, helping to resolve principal–agent problems and foster transparency (Parenti et al., 2022).
Chile’s experience also highlights blockchain affordances. Previously, traditional centralized databases in the country could be easily hacked or manipulated by third parties. This vulnerability, combined with a non-transparent organizational culture, fostered an environment ripe for the abuse of authority and graft. The use of blockchain technology, pioneered in 2018 by the National Energy Commission (CNE) under the Energía Abierta project, has transformed the landscape of information recording. Real-time, immutable energy data is now accessible to the public, making it significantly easier to audit compared with traditional databases (Parenti et al., 2022). Consistent with previous cases, the Chilean experience highlights how applying blockchain to the recording of energy data introduces critical technology affordances, namely, transparency, immutability, and auditability, to the management of the country’s energy sector.
On the contrary, framing DLT in blockchain as a cure-all is often dismissed as a techno-solutionist marketing hype. First and foremost, the prevailing narrative regarding the immutability of blockchain transactions has faced increasing scrutiny. While modifying recorded blockchain data requires approval from nodes, the system, however, is not immune to manipulation if a majority of nodes collude, a scenario known as a 51% attack (Baquero, 2023). In addition to the aforementioned points, observations have also been raised about the integrity of the data initially entered into the system. A scenario could exist where false information was deliberately input to facilitate corruption from the very outset. Viewed from a different angle, blockchain data is also vulnerable to tracing. Baquero (2023) warned that blockchain data faces the challenges of linkability and reversibility. The first challenge involves revealing the identities of transacting parties via behavioral analytics. The second refers to hackers reversing hashing or encryption to its original state, making the data visible to third parties. This observation on immutability shows that people still do not fully grasp blockchain adoption (Cagigas et al., 2023). Instead, people view blockchain merely as a technology that offers quick and easy solutions, a mindset that aligns with the critique of techno-solutionism (Morozov, 2013).
Blockchain can be subjected to misuse, which can take the form of unauthorized access or modification of information, data breaches, exfiltration, or software piracy. While permissioned blockchains (i.e., private and consortium chains) offer faster transaction speeds, their transparency is less guaranteed compared with permissionless (public) or hybrid blockchains. Furthermore, because permissioned networks are controlled by fewer authorities, they may be more susceptible to the potential risk of a 51% attack. In 2017, the Indian state of Andhra Pradesh implemented a private blockchain to enhance land administration. However, research indicates that while landowners are notified of changes to registration and deed records, they lack full control over their data. Furthermore, instances of poor data recording standards have been observed (Kshetri, 2022).
In China, blockchain adoption is driven by the belief that technology fuels modernization, serving as a catalyst for a competitive digital economy. This trajectory explicitly exemplifies the concept of techno-solutionism. However, regarding the application of blockchain in the agricultural sector, it appears that instead of enhancing data efficiency, the technology has been utilized primarily as a tool for state surveillance and monitoring (Hung, 2024). Recent research indicates that the growing use of blockchain technology in the agricultural sector aims to maximize state control over farmers’ livestock assets and data (Shen et al., 2023). The case of China exemplifies how blockchain can be misused (deviated from its original purposes); instead of providing affordances, it imposes constraints.
Aside from the points raised above, several additional constraints of blockchain also merit attention. According to research by Cheesman (2025) regarding Jordan’s experience in piloting blockchain for aid allocation to refugee women, significant constraints were identified. First, there was confusion among staff about the functionality of blockchain. Qualitative data revealed that while staff members praised blockchain as a futuristic technology, when questioned about its mechanics, they responded: “We don’t know; don’t ask me about blockchain.” Notably, this refusal to explain the technology occurred even with a staff member purported to be the group’s foremost blockchain expert. Second, there was an illusion surrounding the technology. Blockchain was viewed as a “magic technological object” capable of solving all problems, despite the fact that certain cited applications, such as cash disbursement, do not necessarily require blockchain solutions. In fact, case studies regarding Colombia’s procurement and Chile’s energy data consistently indicate that the awareness, knowledge, and skills of stakeholders involved in blockchain implementation remain one of the key constraints.
Finally, specific technological constraints are inherent to the operational mechanisms of permissionless and hybrid blockchains. While these two types of blockchains guarantee greater transparency in data storage compared with a private one, they face challenges regarding confidentiality and transaction speed. These limitations stem from their permissionless nature, which requires the involvement of numerous network nodes. Furthermore, prior to blockchain implementation, significant socioeconomic factors, including costs, governance, regulations, and data privacy, must be carefully considered (Cagigas et al., 2021; Kshetri, 2022; Semenzin et al., 2022).
Upon examining the actual experiences of blockchain from the above public sector use cases in a number of countries, it is evident that the affordances of blockchain (e.g., enhancing transparency) align with actual practical experiences, particularly when compared with traditional pre-blockchain methods. However, recognizing these affordances without a sufficient understanding of technology constraints has led to unrealistic expectations and claims. The actual implementation of blockchain brings about numerous challenges, as highlighted through a review of the aforementioned case studies. A critical issue is that in many countries, particularly in the Global South, blockchain adoption is often influenced by techno-solutionist perspectives, viewing the technology as a “quick fix” or “quick win.” This occurs even though structural reform would likely be a more effective solution; nevertheless, such reform is far more difficult to achieve due to the complex systemic elements involved, leading governments to resort solely to the introduction and application of new technology. In the context of developing countries, one observation is that blockchain adoption can serve, at the very least, as a tool for the government to signal political will in combating corruption, even if the technology’s practical worth is debatable.
Blockchain in Thailand
In Thailand, the adoption of e-services is generally claimed to have improved both efficiency and transparency of public service provision (Tengratanaprasert and Prateeppornnarong, 2021). Nevertheless, the efficacy of some e-services is also faced with practical challenges. Take e-GP as an example, although the system can suppress overt fraud like bid rigging, its institutional efficacy is contingent upon rigorous enforcement mechanisms (Rotchanakitumnuai, 2013). Illicit collusion remains a risk, that is, procurement officials may circumvent system controls by disclosing sensitive bid data to favored operators in exchange for financial inducements, thereby compromising the competitive integrity of the tendering process (Prateeppornnarong, 2023).
In 2019, the Ministry of Finance launched an initiative to promote the use of blockchain technology among its affiliated departments. The Memorandum of Understanding (MoU) was signed between the ministry and several commercial banks paving the way for the application of blockchain. In collaboration with banks, a private blockchain has gradually been adopted at the Comptroller General’s Department having a remit to run the public procurement system, and the three other agencies discharging tax and revenue collection duties, namely, the Revenue Department, the Customs Department, and the Excise Department. Blockchain is applied to certain types of work of each aforementioned department. For example, at the Comptroller General’s Department, a blockchain is used for issuing electronic letter of guarantee (e-LG) in the public procurement system, making sure that the process is speedy, reducing a risk of forgery and corruption, while it is used at the Revenue Department for VAT refunds for tourists, enhancing the efficiency of the service and transparency. Noting that blockchain is introduced on a trial basis for the other two departments at this stage (Prateeppornnarong, 2023).
Research design and methodology
Design frame and approach
As blockchain has only recently been adopted in the Thai public sector, examining the adoption of such technology is an uncharted territory requiring suitable research design and approach. As a result, the design of this research complies with a qualitative methodology. The exploratory research design frame was applied as it is arguably useful for examining the topics with scant evidence-based literature from which one might develop hypotheses to test deductively. A phenomenological approach, emphasizing upon “studying lived experiences of various human phenomena” (Cilesiz, 2011: 493), was also adopted for examining how the relevant stakeholders make sense of their experiences with the use of blockchain as a phenomenon that is increasingly pervasive in modern society and is gradually being integrated into their daily work routines (Cilesiz, 2011).
Sampling and sample size
Criterion sampling was used as a main sampling technique to ensure that the samples are qualified for research participation. The criteria for selecting the sample group for this research consist of the following: (1) direct experience regarding blockchain or expertise regarding digital technology (focusing on blockchain). That is, participants must be individuals with positions and duties in supervising the agency’s blockchain usage, or be coordinators with stakeholders in the agency’s blockchain network, or be policymakers for the usage and governance of the agency’s blockchain, or be experts in applying digital technology, especially blockchain, to public administration; and (2) participants must have work experience in the agency for 3–5 years or more, in order to be able to understand the work context in government agencies and the use of technology to improve work conditions to a certain level. To ensure depth of insight, snowball sampling was also used to recruit the “hard-to-reach” participants meaning the very people who are knowledgeable about blockchain but may not already be in the limelight; for instance, back-office staff, from either the public or private sector, who are working behind the scenes to propel the implementation of blockchain within the Thai government (Bryman, 2012).
A total of 30 individuals were recruited for this research. The majority were officials responsible for the operational management of blockchain technology within the Comptroller General’s Department, the Revenue Department, the Customs Department, and the Excise Department. The remaining participants were experts from key agencies driving the Thai government’s digitalization policy, specifically the Digital Government Development Agency (DGA), the Electronic Transactions Development Agency (ETDA), and the Office of the Public Sector Development Commission (OPDC). In the recruitment process, the researcher approached relevant organizations through official permission letters outlining the criteria for participants regarding their experience and expertise. The backgrounds of the interviewees assigned by these organizations were verified as thoroughly as possible to ensure their ability to share genuine insights and perspectives on blockchain application. The snowball recruitment method utilizes referrals from existing participants and/or personal networks to reach potential subjects.
Data collection
This research has been approved by the Institutional Review Board (IRB) COA No. 2022/0032, prior to data collection and the undertaking of the research fieldwork which took place between June and December 2022. The collection of primary data was carried out using a semi-structured interview. The interview was mainly centered on three components: the properties of blockchain and DLT, technology affordances and constraints of blockchain in government based on the participants’ hands-on experience, and the participants’ perspectives on how government agencies and their personnel should adapt themselves to the working environment where blockchain operates.
Regarding research ethics in the data collection and analysis process, it is important to note the high sensitivity of corruption-related issues. Therefore, when interpreting raw data and presenting the findings to readers, the researcher has edited wording that might be construed as implicating specific individuals or groups. The tone of the language has also been softened, avoiding definitive assertions regarding whether or how corruption actually occurred. These measures were taken to prevent potential litigation following the publication of the research findings.
Interviews were conducted through electronic means. The duration of interviews varied between 30 and 60 minutes. Each participant was informed of the objectives of the study and asked to give verbal consent prior to the interview. The interview was audio and video recorded. Nonetheless, all participants were assured of anonymity and confidentiality. For these reasons, the word “interview” and the number indicating which interviewee is being cited are used in this article. This study is not large-scale qualitative research; thus, the recorded interview data were manually transcribed into transcripts. Documents (e.g., official reports, research reports, rules and regulations) are of vital importance in undertaking research, documentary research was, therefore, adopted as another data collection approach for secondary data.
Data analysis
Thematic analysis was employed as the analytical technique for the contextual data collected for this research. This very technique involves data interpretation and coding where inductive reasoning, which is the process of going from specific details examined to broader categories of findings (Thomas, 2013), is applied.

The process of data analysis.
The data analysis process begins with the constant comparative method, which involves comparing raw data to determine the frequency with which specific details (e.g., ideas, pain points) are discussed. Pairing the data from in-depth interviews and document study is an essential part of this initial process of analysis. This approach not only establishes “data triangulation,” a methodological approach that mitigates the bias inherent in single-source data collection (e.g., the possibility that the civil servants interviewed inflated the utility of blockchain), but also ensures that interpretation of the findings and coding leading to theme identification are grounded in the data, not the researcher’s mind. All of this enhances the research’s credibility – or “validity,” in quantitative terms (Ahmed, 2024; Golafshani, 2003; Patton, 1999).
The data analysis proceeded through three distinct stages. First, open coding was employed to break down the raw data, meticulously marking up identifying details with initial keywords to capture the essence of distinct points. The process then moved to axial coding, which involved an iterative rereading of the initial codes. During this phase, the focus shifted to finding conceptual connections and commonalities, allowing the researchers to group scattered codes into coherent subcategories. The analysis culminated in selective coding, a high-level synthesis where refined categories were rigorously evaluated for thematic specificity and selected to represent the core themes of the research (Braun and Clarke, 2006; Thomas, 2013).

Example of thematic coding.
The coding process was conducted manually. While the core themes (see Figure 5) were informed by the research objectives, the subthemes were not preconceived; rather, they emerged inductively from the collected data, grounded in the participants’ experiences and viewpoints. To ensure the dependability (reliability) of the analysis, an inquiry audit was employed. This process involved external experts – specifically the research grant committee and full project reviewers – examining the analytic workflow to validate the emergence of the themes (Ahmed, 2024).

Themes of research findings.
Research findings
The empirical findings of this research clustered around the perceived and actual affordances and constraints of using blockchain to curb public sector corruption in Thailand. The balance of evidence suggests that while blockchain can meaningfully contribute to government anticorruption efforts, some significant constraints of blockchain technology are also highlighted; as a result, blockchain technology is certainly not a silver bullet for anticorruption.
Affordances of blockchain
Transparency and immutability of data storage
The following interview excerpts demonstrate how participants perceived and experienced the affordances of blockchain, specifically data transparency and immutability, within government contexts: Considering from all angles, I believe that blockchain ensures transparency and is useful because every stakeholder in the network is notified of any transactions input into the system. In this case, any data fabrication, data falsification or corruption will be known instantly. (Interview 6, Participant no.1 from the Excise Department, June 2022) If we [the Comptroller General’s Department] use blockchain for the entire system of e-GP [electronic government procurement], the public procurement process will become even more transparent. The key reason is such technology helps prevent fabrication of information. Take the e-LG (electronic letter of guarantee) as an example, in the past, nobody knew. . ., even though the e-service system was adopted, there might be some fabrication of information [on the guaranteed amount in the event of default] on the letter of guarantee, but these days, e-LG on blockchain instill our confidence in the process. (Interview 14, Participant no.3 from the Comptroller General’s Department, June 2022)
As can be seen from a representative sample of interviews, the people involved highlight two specific affordances of blockchain’s data storage transparency – the notification of transaction requests and the accessibility of data to all nodes. Both aspects reflect the underlying distributed nature of blockchain technology. While the first interview quotation simply reiterates the advertised and commonly known features of blockchain, reflecting how influential techno-solutionist rhetoric is among government officials, it adequately demonstrates that the involved personnel understand its core functions. Crucially, the implementation of e-LG on the blockchain highlights officials’ firsthand experience with the technology’s practical affordances. Most notably, it demonstrates how blockchain guarantees transaction immutability, thereby preventing rent-seeking behavior in the public procurement process. Furthermore, participants from the Comptroller General’s Department shared valuable insights into how blockchain, unlike traditional e-service systems, ensures data integrity and fosters confidence in the e-LG process. Based on the aforementioned experiences, it is evident that blockchain enhances transparency, immutability, and auditability, particularly when compared with traditional data storage systems. Noting that Thailand’s experience with blockchain aligns with the experiences of several jurisdictions cited in the literature review, such as Chile.
Consistent with the interview data, this study’s documentary analysis reveals that in Thailand, e-services like e-GP are significantly less effective at combating corruption than blockchain technology. The primary reason is that each e-service system is “owned” by the specific department that operates it (in this research, this is called the “ownership problem”). As previous studies suggested, while electronic systems record data more efficiently than traditional paper-based methods, their centralized control by a single entity makes them highly vulnerable to abuse, particularly in countries with systemic corruption (Prateeppornnarong, 2023; Tengratanaprasert and Prateeppornnarong, 2021).
Anticorruption
The transparency and immutability affordances of blockchain create a general expectation that it can help fight corruption. Going further, several participants in this research detailed how these specific features can be operationalized, for example: I totally agree that blockchain helps addressing corruption but it does not help with corruption prevention, what it does is to deter corrupt practices. Why? Metaphorically speaking, the impact of blockchain is similar to that of police patrol as criminals would find it difficult to commit crime while patrol officers are on the street. This helps reduce the chance of crime being committed from time to time but what it does not do is bringing crime to a complete stop. The use of blockchain certainly helps raise people’s awareness that once the data has been input, it is difficult to change, so if anyone attempts to falsify the data, the risk of being caught is high. Despite this, at the end of the day, in case anyone wants to corrupt the whole system, they could bear the risk and do so anyway. (Interview 20, Participants no.2 from the Digital Government Development Agency (DGA), August 2022)
This interview provides a more detailed perspective, demonstrating that while blockchain technology can be utilized for anticorruption efforts in the public sector, its function is primarily as a deterrent rather than actively halting or preventing corruption from occurring. Furthermore, the informant reflected that blockchain is not a flawless technology; ultimately, it remains a tool susceptible to human manipulation. This interview data is highly valuable in tempering overly high expectations surrounding blockchain, grounding them in reality. It also clearly demonstrates the informant’s genuine understanding of the technology’s pros and cons. Another crucial point is the concluding portion of the interview, which discusses the potential domination of an entire blockchain network. This illustrates that blockchain itself can be misused, aligning with China’s experience of deploying blockchain for state surveillance regarding agricultural data (see below, “Potential misuse of blockchain”).
Constraints of blockchain
Potential misuse of blockchain
As established in the literature review, blockchain systems are not immune to misuse. Private and consortium blockchains are notably limited in their ability to ensure transaction transparency and immutability. Given that both are permissioned networks, authority over data access and historical records remains centralized among a few key entities. Echoing this concern, study participants shared the following perspectives on how permissioned blockchains may be misused: If a private blockchain is adopted and there are a few nodes, or at least not too many, in the network, collusion between them [nodes] is possible, right? What I meant to explain is that the opportunities for blockchain to successfully minimize corrupt practices, to a significant degree, depends on the number of nodes involved in the system. Why is blockchain dubbed as an immutable ledger? Because when you want to make some changes to any transaction histories, the whole chain of data has to be modified throughout but in case there are not many users [nodes] in the network, the question arises if it is worth doing so. (Interview 20, Participant no.2 from DGA, August 2022)
Considering these perspectives, a blockchain’s anti-corruption affordances and constraints are linked to its specific level of decentralization. In this respect, adopting permissioned blockchains, which naturally exhibit moderate to low degrees of DLT, will present anticorruption challenges comparable to those faced by traditional e-government services. The above interview data further illustrates that blockchain technology does not operate entirely on its own. The functioning of blockchain is still based, to some extent, on human preferences, decisions, and integrity in the first place. Therefore, the misuse of blockchain technology is not beyond expectation.
Documentary analysis supports the above discussion, indicating that in countries experiencing systemic corruption and high politicization (e.g., Thailand), blockchain technology risks being co-opted by vested interests. An incumbent government might implement a private blockchain to project an illusion of transparency while deliberately choosing the least impactful model. This mirrors historical trends with anticorruption agencies (ACAs), where regimes adopted the rhetoric of good governance by establishing an ACA, but intentionally deprived it of the independence, authority, and resources necessary to function effectively (Prateeppornnarong, 2021).
Cost-efficiency
Apart from potential misuse of blockchain as the main constraint of blockchain, concerns regarding cost-efficiency emerged as another primary practical constraint, as voiced by the majority of participants throughout the interview process. Selected excerpts from these interviews are provided below: It is clear to us [the Office of the Public Sector Development Commission (OPDC)] that, in the Thai context, blockchain is not suitable for all the existing e-service systems that we have. We have to think seriously about the application of blockchain and cost-efficiency. In our view, the use of blockchain may be cost-effective in case of the provision of any public services that involve various agencies. (Interview 25, Participant no.1 from OPDC, August 2022)
The interview above reflects the research participant’s observation about the cost-effectiveness of adopting blockchain technology in the Thai public sector, given its high implementation and maintenance costs. This observation on cost-effectiveness aligns with many other studies on blockchain in government globally (e.g., Cagigas et al., 2021). For these reasons, an assessment may be required to determine whether public sector corruption, within a specific country’s sociopolitical context, truly necessitates the use of blockchain, and if so, in which specific areas. In addition, it should be considered whether these corruption issues could still be mitigated through non-technological methods (Morozov, 2013), in order to identify the most appropriate and cost-effective approach.
Regulatory governance of blockchain
Several research participants highlighted Thailand’s regulatory framework for blockchain as a significant practical constraint. One participant explained: In Thailand, although we now have some pieces of legislation on digital technology and its platform such as the Electronic Government Service Act B.E.2565 [2022], in the future, we need more of this kind of legislation like legislation on blockchain to streamline effective law enforcement. (Interview 29, Participant no.1 from the Electronic Transactions Development Agency (ETDA), August 2022)
As reflected in the interview, establishing regulatory frameworks for blockchain governance poses a distinct challenge. Such a challenge is also evident in other countries that have adopted blockchain (e.g., Baquero, 2023; Cagigas et al., 2021). Currently, the majority of government agencies utilizing blockchain operate under an MoU established between the Ministry of Finance and commercial banks acting as service providers. The Revenue Department is the sole government entity possessing dedicated regulations regarding blockchain-facilitated tax and revenue collection. All of this gives rise to regulatory uncertainty if the application of blockchain is expanded into more areas of work in the aforementioned agencies.
Security and confidentiality
Security and confidentiality are of particular concern in blockchain operations. During the interviews conducted for this research, several participants highlighted these issues, noting, for example: Right now, it is generally claimed that blockchain technology will not be easily suffered from a system outage or be easily vulnerable to hacking, or even if it was hacked, every node would know immediately about the problem. However, we don’t know if blockchain would be hacked by a more advanced technology in the future. This poses a serious challenge in terms of data integrity and confidentiality. (Interview 30, Participant no.2 from ETDA, August 2022)
As the preceding interview highlights, blockchain implementations can be prone to operational vulnerabilities. This is in line with Baquero’s (2023) arguments over data vulnerabilities in blockchain platforms, specifically concerning issues of linkability and reversibility. Arguably, these risks are most pronounced in public blockchains, where the affordances of transparency and immutability often come at the expense of security and confidentiality constraints due to the large volume of network participants.
Digital skills and organizational culture
During the interviews, the participants unanimously agreed that blockchain is significantly more advanced than any technology they had previously encountered. Accordingly, they all identified insufficient digital literacy as a primary individual-level barrier: I can tell you what, a rough estimate of the public officials who are technologically skilled is no more than 10 percent, most or all of them are computer technical officers. Nonetheless, in the near future, I think we need to upskill our workforce, making officials become familiar with new technology. For instance, those officials who work closely with the system on blockchain have to have skills like data entry, data analytics etc. This is not just to make sure that they are capable of using technology in their daily routine but also to ensure that there will be no inadvertent error. (Interview 1, Participant no.1 from the Customs Department, June 2022)
An example of the deficit in digital skills and blockchain comprehension can be observed in the case study of blockchain implementation for the management of female refugees in Jordan. In the case of Thailand, the aforementioned interview data clearly demonstrates that the proportion of individuals who understand and utilize blockchain, alongside other digital technologies, remains exceptionally low. If the application of blockchain is to be scaled up, preparing the populace is therefore of paramount importance.
In addition to an individual-level barrier, numerous participants cited public sector culture as the most significant constraint limiting the institutional capacity to implement blockchain technology. One of them pointed out that: Previously we [OPDC] have consulted with DGA on the approach for encouraging agencies in the public sector to share their information across the board. Currently, most of them are quite possessive about access to their data, not willing to share them with any other agencies. So this kind of workplace culture, if not changed, would be very difficult for blockchain to be adopted more widely. (Interview 28, Participant no.4 from OPDC, August 2022)
The documentary analysis in this research revealed that most government agencies in Thailand operate in silos, with minimal interagency communication. A primary reason that these agencies restrict data access is the contemporary perception that data are a powerful operational asset. This is why agencies fear that relinquishing control over their data equates to a loss of power and jurisdiction, which could negatively impact both their organizational standing and budget allocations (Tengratanaprasert and Prateeppornnarong, 2021).
Discussion
In light of the empirical findings of this research, it is apparent that DLT strengthens users’ confidence in the system, assuring them that the modification or alteration of critical data within the database network can be deterred when blockchain is adopted. Theoretically, this specific affordance reflects the technology’ s capability to resolve information asymmetry, which typically leads to the principal–agent problem. The findings also indicate that, comparatively, blockchain technology can establish both vertical and horizontal transparency more effectively than previously utilized e-government systems. This is primarily because blockchain mitigates the “ownership problem.” Ultimately, these points collectively support the argument that blockchain can help curb corruption in the public sector.
This research also highlights the operational and practical constraints of blockchain in government. Operationally, blockchain is not strictly immutable (Ølnes et al., 2017) and remains susceptible to linkability and reversibility attacks (Baquero, 2023). Besides, interview data suggests a high potential for systemic misuse, particularly in permissioned networks, which can be exploited for corrupt collusion or state surveillance. Practically, the findings also highlight issues related to cost-effectiveness, regulatory governance, security and confidentiality, and digital skills. These constraints align with findings from similar studies conducted globally (Cagigas et al., 2021). The research also points to a constraint specific to the Thai context, which is the data-hoarding organizational culture within the Thai public sector. There is a reluctance to share data due to concerns that doing so might diminish the organization’s significance.
Weighing the affordances and constraints of blockchain raises the broader question of whether governments should use it to combat corruption. The answer is multidimensional, depending largely on a country’s specific sociopolitical context. It should be noted that scholars and practitioners profoundly familiar with the issue of corruption universally concur that resolving this problem necessitates a focus on structural reform across economic, social, and political dimensions. Notwithstanding, such an undertaking often resembles an idealistic aspiration, particularly within the context of developing countries in the Global South. In Thailand, structurally resolving corruption and poverty has constituted a central campaign platform for nearly all political parties during general elections over the past three decades. Nevertheless, upon these parties’ ascension to power, structural anticorruption initiatives are consistently undermined by political compromises.
Considering this empirical reality, while this research steadfastly maintains that advocacy for structural reform must persist, it posits that technological interventions can effectively mitigate immediate challenges. Absent such measures, public sector corruption risks total neglect, which could ultimately exacerbate corrupt practices. Metaphorically, the application of blockchain technology to combat corruption is analogous to a physician managing a chronic disease that evades an immediate cure; symptomatic treatments must be administered to prevent further deterioration of the condition. However, given its inherent constraints, blockchain’s effectiveness relies heavily on its integration with other factors. Rushing its adoption in the public sector without strategic assessment risks wasting valuable resources. Establishing a robust legal and regulatory framework is crucial for effective governance; without it, the long-term delivery of blockchain-based public services may face significant challenges regarding the legality and validity of these actions. Finally, upskilling public officials in digitalization is an absolute necessity.
Most importantly, this research presents a critical lesson for countries grappling with systemic corruption. Blockchain can be weaponized as a performative façade generating unearned political legitimacy and creating an illusion of transparency while avoiding substantive reform. Conversely, even when genuine political will exists to enhance transparency, policymakers must ensure that adopting advanced technologies transcends superficial signaling. To safeguard against ineffective implementation, civil society organizations (CSOs) must serve as central partners alongside the public sector in overseeing blockchain’s deployment.
Conclusion
Blockchain adoption in government has been studied for some time, but there is little empirical evidence to date in relation to the application of such technology in the countries plagued by systemic corruption. Grounded in an exploratory research design frame and a phenomenological approach, this study investigated blockchain in government using Thailand, a developing country in Southeast Asia engulfed by systemic corruption and political patronage, as a research context to see whether the use of such technology helps in curbing corruption.
This research paper carries theoretical, practical, and methodological implications as follows. Through a review of literature and data analysis, the present research discussed the principal–agent theory and the concept of transparency. It engaged with critiques of blockchain usage through the lens of techno-solutionism (blockchain solutionism) and technology affordance and constraint theory, and applied all the theories-in-use with the empirical evidence to demonstrate that data storage transparency and immutability affordances of blockchain can deal effectively with informational and behavioral uncertainties and asymmetric information, addressing the principal–agent problem. DLT in blockchain is arguably useful for ensuring vertical and horizontal transparency in government transactions as well.
However, policymakers, including heads of government agencies, should not adopt the techno-solutionist discourse and perceive blockchain as a quick fix or a panacea for solving corruption. The present research also underscores technology constraints of blockchain, including operational constraints (i.e., potential misuse, and security and confidentiality) and practical constraints (i.e., cost efficiency, regulatory governance, and digital skills and organizational culture). Methodologically speaking, while previous research on blockchain has been very much literature-review-based studies, this research adopted a qualitative methodology contributing to the existing literature on blockchain in government and anticorruption.
Based on the research findings, it is apparent that DLT in blockchain is useful for enhancing transparency in government transaction, creating a deterrent effect upon corruption; hence, the adoption of blockchain in government can provide a solution to the problem of corruption in the public sector. In the case of countries engulfed by systemic corruption, the introduction of blockchain in government should not be considered in isolation from sociopolitical and economic factors; equally important, it also requires careful consideration. In those countries, policymakers may have to undertake a feasibility study to gauge whether the adoption of blockchain will become a workable option to curb public sector corruption considering the peculiarities of the economic and sociopolitical contexts. The multisectoral involvement is also required to ensure that blockchain will not be misused for vested interests. Representatives from CSOs should be enabled to play active roles in the application of blockchain in government. Finally, institutional capacities and individual digital capabilities are essential for success in the application of blockchain requiring adequate preparation and training.
In the Thai case, the findings show that although blockchain is contributing to corruption control in certain parts of the Thai public sector, a comprehensive review is required to determine the optimal areas for blockchain implementation in government, focusing on maximizing data management capabilities, enhancing transparency, and ensuring cost-effective operations. This research argues that the current application of blockchain to e-LG, for example, can be expanded to other areas of the e-Government Procurement (e-GP) system, particularly in construction procurement, which is one of the most corruption-prone sectors. The complete collapse of the State Audit Office (SAO) building under construction in 2024 serves as a crucial cautionary tale (Sangsinchai, 2025).
The adoption of technology means there is a need for a cultural change, especially the silo culture (Maragno et al., 2023). The change will aid interorganizational cooperation leading to interoperability of blockchain networks in government. This research recommends practically enforcing the sections of the 2019 Digital Government Administration and Services Act that promote data integration among state agencies for the public good. Last but not least, assigning a role for CSOs in regulatory governance of blockchain operations is also recommended (Prateeppornnarong, 2023). At present, there are precedents for active civil society engagement in monitoring good governance in the public sector. A notable example is the Public Procurement and Supplies Administration Act B.E. 2560 (2017), which mandates that CSOs dedicated to anticorruption serve as observers in accordance with the Integrity Pact (Prateeppornnarong, 2022).
This research is subject to a number of limitations, as follows. First, while the use of a qualitative research methodology is appropriate for the context and scope of this study, the findings cannot be generalized because they are context-specific. Second, the agencies implementing blockchain technology are exclusively under the Ministry of Finance, which restricts the experiences and perspectives to personnel working within the organizational culture of this specific ministry. Third, the majority of the interviewees are civil servants from departments within the Ministry of Finance that utilize blockchain; this may introduce bias as the interviewees may overstate the benefits of blockchain. Fourth, there are very few published case studies internationally that specifically explore the use of blockchain to foster transparency and combat corruption in the public sector, particularly those providing details on implementation processes and outcomes. Fifth, rapid technological advancements may limit the duration for which the contributions of this study remain relevant.
