[TL;DR]
- The current education system is facing structural limitations such as diploma forgery issues, the monopoly of centralized educational institutions, and the fragmentation of learning data.
- Blockchain can fundamentally solve these problems through an immutable digital degree system, a decentralized education evaluation network, and personalized learning portfolio management.
- Abstracting technical complexity and achieving global standardization through the WaaS (Wallet-as-a-Service) model can reduce the digital divide and expand access to education, ultimately enabling true equality of educational opportunities.
1. Structural limitations and crises of the current education system
1.1. The serious reality of diploma and certificate forgery
As of 2025, academic credential forgery is no longer an isolated misconduct but a structural issue worldwide. According to a recent survey by the International Institute of Education, cases of diploma forgery discovered by global companies during hiring processes have increased by more than 15% annually. This problem is particularly severe in fields such as IT, finance, and healthcare.
One of the biggest problems is the sophistication and systematic nature of fake degree production. In the past, most forgeries were crude certificates, but now highly organized criminal networks are perfectly replicating the logos and formats of actual universities and even entering fake graduate information into online databases of those universities. Some services even offer “package deals” that include fake transcripts, letters of recommendation, and even access to alumni networks.
The rapid expansion of online education has further widened the blind spots of the verification system. With the explosive growth of remote learning since COVID-19, traditional in-person verification methods have been rendered ineffective, resulting in a proliferation of fake online universities and accreditation bodies. Especially in the case of overseas online degree programs, local verification is difficult, creating even larger blind spots. This, in turn, leads to a vicious cycle that undermines the credibility of honest online education institutions.
More seriously, current verification systems cannot keep up with these changes. Most companies still rely on 20th-century methods of directly contacting the issuing university to verify submitted diplomas. This process requires significant time and cost, and in the case of international verification, it is practically impossible due to language barriers, time differences, and varying educational systems in each country.
These difficulties in verification exacerbate information asymmetry. While forgery syndicates continue to develop more sophisticated techniques, the parties responsible for verification remain stuck in fragmented, individual responses, widening the gap. A further problem is the lack of information-sharing systems among verification agencies. Even if Company A discovers that a candidate has submitted a fake diploma, this information is not shared with other companies, enabling the same individual to repeatedly use forged credentials at multiple organizations. This creates a structural loophole.
Ultimately, the accumulation of these problems has led to a sharp decline in trust throughout the entire education market. Hiring managers can no longer trust submitted academic certificates, resulting in honest candidates being subjected to suspicion. At the same time, unqualified individuals are hired into important positions using fake credentials, frequently lowering organizational productivity and raising fundamental questions about the usefulness of academic credentials as a signaling mechanism.
1.2. Monopoly and inequality of centralized educational institutions
One of the root causes of diploma forgery is the fact that a few prestigious educational institutions monopolize the gateways to social success. The extreme degree-centrism seen in countries like South Korea and many other Asian nations is the most serious side effect of the centralized nature of the education system, and it continuously fuels the structural demand for fake degrees.
The lifetime monopoly power of a prestigious university diploma is often valued more highly than an individual's actual capabilities or continuous learning efforts. In a society where university pedigree decisively affects employment, promotion, and social status, the value of ongoing learning and practical experience after graduation is relatively disregarded. Such a system not only hinders the establishment of a lifelong learning culture but also pressures those who did not graduate from prestigious universities to consider purchasing fake degrees.
This monopolistic structure intensifies the stratification of educational opportunities in conjunction with economic inequality. According to Statistics Korea, private education spending in Korea exceeds 26 trillion KRW annually, clearly illustrating the gap in educational opportunities depending on household income. Children from high-income families receive the best private education and gain advantages in entering prestigious universities, while children from low-income families struggle to access even basic educational opportunities. Worse still, with annual tuition at prestigious private universities exceeding 10 million KRW, many students have no choice but to rely on student loans, resulting in long-term financial burdens even after graduation.
These economic barriers further accelerate regional educational inequality. The concentration of prestigious universities in metropolitan areas forces students from provincial regions to invest more money and effort to obtain equivalent educational opportunities, structurally entrenching educational inequality based on birthplace. The undervaluation of regional universities accelerates the outflow of talented students to urban areas, perpetuating a vicious cycle that hampers regional development.
In this unequal structure, the evaluation system itself is operated under the monopolistic authority of a few institutions. University entrance exams, civil service exams, and various certification tests are all evaluated according to uniform standards set by a small number of institutions, preventing diverse talents and individual characteristics from being properly recognized. This results in the production of standardized types of talent, moving further away from the creativity and diversity required by modern society. A further problem is that grading standards and evaluation methods are not transparently disclosed, leaving learners confused about what and how they should study.
Ultimately, this centralized monopolistic structure creates rigidity throughout the entire education system. In a system where a single evaluation determines a person's lifelong value, opportunities for continuous growth and development are limited, deepening the mismatch between the talent society needs and the talent the education system produces. This leads to unfair distribution of opportunities for individuals and inefficient use of human resources for society as a whole, forming a vicious cycle.
1.3. The problem of fragmented learning data and outcomes
Another side effect of this centralized monopolistic structure is that an individual's learning history is stored fragmented across countless institutions. In the current education system, records from elementary school to university, as well as from private academies, online course platforms, vocational training centers, etc., are scattered in different systems, making it nearly impossible to construct a comprehensive learning portfolio.
This fragmentation further exacerbates the problem of diploma forgery mentioned earlier. In situations where even learners themselves cannot accurately grasp their own learning history, some rely on memory and provide incorrect information, which may lead to unintentional misinformation. Worse, if an institution goes out of business or changes its system, there is a constant risk of complete loss of learning records from that period. In such circumstances, individuals are forced to seek alternative ways to prove their learning history, which sometimes leads to irregular or illegal methods.
The lack of compatibility among educational institutions further complicates this problem. For example, a subject taken at University A may not be recognized at University B, or a course completed on an online platform might have no value in an offline educational institution. This forces learners to restart from scratch whenever they change institutions, ultimately becoming a structural barrier to lifelong learning.
In today's world, where continuous retraining is increasingly necessary due to rapid technological changes, this fragmentation problem poses an even greater challenge. Most adults have no proper records or certifications for learning activities after formal schooling, so their continuous self-development efforts are not socially recognized. In particular, the separation between job-related training and academic degrees results in various educational programs aimed at acquiring practical skills or knowledge being treated separately from formal education.
This situation devalues microlearning and informal learning. Modern learners tend to prefer microlearning that focuses on acquiring specific skills or knowledge in a short period, but such forms of learning are rarely recognized by the existing certification system. As a result, even if someone possesses a high level of expertise, there is no objective way to prove it, leading them to choose inefficient methods simply to obtain official certification.
The most fundamental problem is that ownership and control over individual learning data are unclear. In most cases, data generated at educational institutions is considered the property of the institution, making it difficult for learners to freely use or transfer their own learning history. This not only restricts learners’ autonomy but also hampers competition in the education market. Furthermore, due to the dilemma between privacy and accessibility, excessive security sometimes paradoxically makes it difficult for learners themselves to access their own data.
This fragmentation problem acts as an even more serious constraint in the global talent market. Learning records accumulated in one country are often not recognized in another, or they require complicated certification procedures, limiting global talent mobility. This restricts individual opportunities and becomes a barrier to securing outstanding talent at the national level, ultimately resulting in inefficient global human resource allocation.
Ultimately, these three structural problems — diploma forgery, centralized monopolies, and data fragmentation — form a vicious cycle that reinforces each other. The monopoly of a few institutions creates demand for fake degrees, fragmented systems make verification difficult, and the challenges of verification further strengthen monopolistic structures. These fundamental limitations cannot be solved through incremental improvements alone but require a paradigm shift in the entire education system.
2. A new paradigm for educational innovation proposed by blockchain
2.1. Tamper-proof digital degrees and certificate systems
As a fundamental solution to the chronic problem of diploma forgery in the existing education system, blockchain technology presents an entirely new dimension of educational certification systems. The core of this system is to provide each learner with a unique blockchain-based digital learning identity and to manage all educational achievements as immutable digital records.
An encrypted digital certificate system offers a fundamentally different approach compared to traditional paper-based diplomas and certificates. The moment a learner completes a course or passes an exam, the achievement is immediately recorded on the blockchain and cryptographically protected. The key point is that these records are stored on a distributed network, making it impossible for anyone to delete or tamper with past records. For example, if a student earns a computer science degree from Seoul National University, that information is permanently recorded on the blockchain with Seoul National University’s digital signature, enabling real-time verification from anywhere in the world.
The most revolutionary change this system brings is the real-time verification of qualifications. When a hiring manager or an admissions officer wants to verify a candidate’s credentials, they can obtain accurate information within seconds without complex document requests or inter-institutional communications. The applicant only needs to provide a digital degree certificate link or QR code, and the verifier can instantly check the authenticity of the information through the blockchain network. This not only reduces the verification process from days to seconds but also guarantees 100% accurate validation.
Furthermore, it becomes possible to build a standardized international certification system. Currently, due to different educational systems and certification methods in each country, the process of recognizing foreign qualifications is very complex and difficult. However, in a blockchain-based system, a common global verification protocol can be used. A digital degree issued in Korea could be recognized with the same level of trust in the United States, Europe, or Asia, significantly lowering barriers to global talent mobility.
The innovation of micro-credentials and badge systems presents new possibilities that transcend the limitations of traditional educational certifications. While traditional degrees and certificates are typically awarded only after completing long-term programs, blockchain systems allow even small-scale learning achievements to be immediately certified and accumulated. For example, mastering a specific programming language, completing a special project, or finishing an online course can all be issued as verifiable digital badges that build up an individual’s learning portfolio.
With such a system, the cancellation or invalidation of learning outcomes can also be transparently managed. In the current system, even if a degree is revoked due to admission fraud or grade manipulation, already issued diplomas can continue to be used. However, in a blockchain system, information about degree cancellations is immediately recorded on the network, so the validity of the qualification is updated in real time. This strengthens the quality control responsibilities of educational institutions and more securely protects the rights of legitimate learners.
2.2. Decentralized educational evaluation and certification networks
One of the most disruptive innovations that blockchain technology can bring to education is the transformation of centralized evaluation systems into decentralized networks. This represents a fundamental paradigm shift that goes beyond mere technical change to involve the redistribution of educational authority and democratization of evaluations.
A multi-party verification-based objective evaluation system is the core mechanism for dismantling the monopolistic authority of a few institutions. Currently, a single university or exam body conducts evaluations and certifies the results alone. In a blockchain-based system, however, multiple independent evaluators cross-verify the same learning achievement. For example, when assessing a learner’s programming skills, various experts independently evaluate the performance, and the results are recorded on the blockchain and synthesized into a comprehensive score. This approach minimizes subjective biases from individual evaluators while greatly increasing trust in the evaluations.
The introduction of a peer-to-peer learning evaluation system will bring even more innovative change. In traditional education, instructors unilaterally evaluate students. In a blockchain system, however, a mutual evaluation network can be established where peer learners assess and certify each other. This is expected to be particularly effective in practice-oriented technical fields or creative domains. Peers working in the same field can review and evaluate each other’s projects, and the feedback and evaluations obtained in this process can all be recorded on the blockchain as objective indicators of competence.
A decentralized certification system by expert groups dismantles the monopoly of existing educational institutions while enabling more practical and realistic evaluations. Through a certification network in which field professionals voluntarily participate, not only theoretical knowledge but also practical skills can be comprehensively evaluated. For example, in marketing, a decentralized certification network comprising active marketers, advertising planners, and brand managers can assess capabilities in campaign planning and execution. This reduces the gap between theory learned in school and practical application, allowing evaluation criteria aligned with the type of talent actually needed in industry.
For such a decentralized evaluation system to operate effectively, automated competency assessment technology integrated with AI is essential. Artificial intelligence can comprehensively analyze a learner’s diverse activities and performance data to provide objective competency assessments. Instead of simply looking at test scores or assignment submissions, AI can evaluate problem-solving approaches during learning, collaboration abilities with peers, and continuous learning motivation to form a more three-dimensional understanding of a learner’s abilities.
The introduction of a reputation-based verification system further strengthens the reliability of decentralized evaluations. The past evaluation histories and accuracy records of each evaluator or certification body are all stored on the blockchain, allowing for objective judgment on who provides more trustworthy evaluations. Evaluators who consistently provide accurate and fair assessments gain high reputation scores and thus receive more evaluation opportunities, while those who give inaccurate or biased evaluations see their reputation scores drop and are naturally excluded from the system through self-regulation.
The ultimate goal of this system is the democratization and diversification of educational evaluation. No longer is a person’s abilities determined by a single uniform standard from a few institutions; rather, they are shaped by the collective judgment of diverse evaluators with various perspectives and criteria. This creates an environment where learners’ diverse talents and characteristics can be more fairly recognized, enabling the construction of an educational ecosystem that aligns with the demands of modern society, which values creativity and diversity.
2.3. Personalized learning portfolio management
The most direct benefit of this decentralized evaluation system is that it enables learner-centered integrated management of learning histories. It provides a foundation for solving the problem of fragmented learning data and for building a truly learner-centric educational ecosystem.
A blockchain-based personal learning history management system allows all of a learner’s activities to be organized into a single integrated digital portfolio. Not only formal learning at educational institutions, but also online course completion, self-taught skills, project participation, volunteer activities, and even hobby-based learning can all be recorded and managed in a verifiable form. For example, if an individual majors in business administration at university, takes data analysis courses online, and develops a mobile app as a personal project, all these activities can be integrated into one portfolio with their respective certifications.
The core of this integrated management is that learners have complete ownership and control over their data. In the current system, each institution exclusively owns the learning records from its courses. In the blockchain system, however, learners themselves manage all of their learning data and can selectively disclose or share it as needed. This greatly expands learners' autonomy, encourages competition among educational service providers, and drives improvements in educational quality.
The implementation of a skill-based talent matching platform is one of the most transformative changes that personalized portfolios will bring. In the existing job market, candidates are often filtered by broad indicators such as university name or major. In a blockchain-based system, however, precise matching is possible based on the specific skills and competencies that individuals actually possess. For example, if a company requires "advanced Python programming skills, experience in data visualization, and leadership in team projects," the system can automatically find and match candidates who meet these criteria.
Such a matching system allows for fair evaluation focused on actual abilities rather than educational background. Even without a prestigious degree, candidates who possess the required skills and experiences can receive equal opportunities, helping to correct the current structure where educational inequality directly leads to employment inequality. From a corporate perspective, it also enables more accurate identification and deployment of needed talent.
The feature of continuous competency updates and tracking holds special significance in the era of lifelong learning. As individual learning portfolios are updated in real time on the blockchain, new skills and experiences are immediately reflected, continuously updating a person’s market value. For example, if someone in IT learns a new programming language or completes training on the latest technology trends, these achievements are instantly added to their portfolio and automatically shown to companies seeking those skills.
A personalized learning path recommendation system can also be implemented based on this portfolio data. AI can analyze a learner’s current competency level, areas of interest, and target job roles to propose an optimal learning path. It can also proactively recommend learning opportunities that help enhance competitiveness by identifying high-demand skills and capabilities in the market in real time.
The ultimate vision of this system is to create an ecosystem where learning, work, and growth are seamlessly connected. All learning experiences and skills accumulated over a lifetime are transparently recorded and recognized, creating an environment where individuals can continuously generate opportunities and grow. This represents a fundamental shift from a one-time degree-focused system to a lifelong learning-centered system, providing a foundation for both individuals and society to continuously adapt and develop in an era of rapid change.
3. Future scenarios of the blockchain education ecosystem
3.1. Global educational institution alliance scenario
As blockchain-based educational certification systems mature, the emergence of global educational consortiums led by major universities around the world is attracting attention as both a realistic and innovative scenario. This goes beyond mere technical cooperation, proposing a new governance model for global standardization and quality assurance in education.
The formation of a blockchain consortium by world-class universities is already taking concrete shape, involving institutions like MIT, Stanford, Oxford, and Seoul National University. These universities are building a common blockchain infrastructure to mutually recognize each other’s degrees and credits. For example, when a Korean student transfers from Seoul National University to MIT after studying for two years, the student can transfer seamlessly based on blockchain-recorded learning histories without going through the complex credit recognition process currently required. Furthermore, it would become possible for a student to study one semester at Seoul National University and the next at Oxford, enabling flexible learning journeys.
At the core of this consortium is the standardization of joint degree programs and credit recognition systems. While some universities currently operate joint degree programs, they are very limited due to complicated administrative procedures and different systems. However, in a blockchain-based system, learners will be able to freely combine courses from multiple universities to design a personalized degree. For example, someone aspiring to become an AI expert could combine computer science courses from Stanford, machine learning courses from MIT, and East Asian culture courses from Seoul National University. All of these would be transparently recorded on the blockchain and recognized worldwide as a valid degree.
The standardization of remote education across borders is one of the most immediate changes that such a consortium would bring. While COVID-19 demonstrated the potential of remote education, concerns remained about quality assurance and accreditation. In a blockchain-based system, even remotely attended courses would have their quality and learning outcomes transparently recorded and verified, making them equally recognized as in-person courses. All processes—from real-time attendance tracking to assignment submissions, assessments, and exam proctoring—would be recorded on the blockchain, eliminating fraud while maximizing flexibility.
These changes will lead to innovation in quality assurance and mutual recognition systems. Currently, each country’s ministry of education or accreditation body manages educational quality individually, making cross-border recognition difficult. In a global consortium, however, shared quality standards and evaluation methods could be applied. All learning objectives, assessment methods, and achievement criteria would be transparently disclosed on the blockchain, and actual learning outcomes would be objectively measured and recorded. This would not only promote quality improvements but also help build globally trusted educational brands.
New models for research collaboration and knowledge sharing are also noteworthy. Research outputs and data from consortium member universities could be securely shared through blockchain, enabling large-scale global research projects. By combining each university’s unique strengths, research networks could be formed to solve humanity’s grand challenges such as climate change, artificial intelligence, and biotechnology. Students would also have the opportunity to participate in these global projects and gain hands-on problem-solving experience.
However, for such a global consortium model to succeed, it is necessary to achieve standardization while preserving cultural and linguistic diversity. Instead of a Western-centric educational model dominating globally, a pluralistic system that respects each region’s unique educational philosophies and methodologies while enabling mutual recognition and exchange must be established. By leveraging blockchain’s decentralized nature, the aim should be to create a truly global education network that is not dominated by any single region or culture.
3.2. Decentralized online education platform scenario
In contrast to the global university consortium, the rise of fully decentralized educational ecosystems is also expected to proceed in parallel. In this scenario, a new education market emerges where experts and learners connect directly without traditional institutional intermediaries.
The rise of expert-to-learner direct education markets is already becoming a reality. For example, current Google engineers directly teach programming, or successful entrepreneurs share their startup know-how. In these cases, professionals sell their knowledge and experience directly. Blockchain technology can greatly enhance the transparency and trustworthiness of such transactions. The actual careers and achievements of experts are recorded on the blockchain in a verifiable form, enabling learners to make more informed decisions about whom to learn from.
In this system, P2P transactions between learners and educators occur directly without institutional fees or complicated administrative procedures. Through smart contracts, conditions for providing educational services, learning objectives, and payment terms can be automatically managed, minimizing potential disputes. For instance, if a learner contracts with an expert to master a specific programming skill within three months, the learning progress and outcomes are recorded on the blockchain in real time, and payment is automatically executed only upon meeting the objectives.
A token economy-based learning reward system will be a core driver of such educational platforms. By rewarding various contributions—such as learning activities, completing assignments, helping peers, and sharing knowledge—with tokens, learners’ motivation can be strengthened, and community participation can be activated. Learners who achieve excellent learning outcomes can receive token rewards, use them to purchase other educational services, or even transition to become educators themselves by teaching their newly acquired skills to others. This creates a natural cycle from learner to educator, accelerating the diffusion and development of knowledge.
Community-based knowledge verification and curation is a key mechanism that ensures quality in such decentralized systems. Instead of traditional educational institutions’ quality control, the learner community itself evaluates and certifies the quality of educational content. Learner evaluations and feedback on each course or content are transparently recorded on the blockchain, allowing quality control through collective intelligence. In addition, experts in specific fields can voluntarily participate in peer review systems to verify content accuracy and currency.
The expansion of microlearning and just-in-time learning will also characterize these platforms. Rather than semester-based or long-term programs, learners can quickly acquire only the knowledge they need at the moment. For example, if someone encounters a specific technical problem at work, they can immediately find and take a short course focused on that problem, solve it, and then share the experience back with the community, creating a virtuous cycle.
However, a major challenge for fully decentralized models is ensuring quality and trustworthiness. While lower entry barriers allow anyone to become an educator, this also increases quality variance. Blockchain-based reputation systems and community verification can partially address this, but there may still be limitations in fields that require professional and systematic education. Therefore, a hybrid model in which traditional institutions and decentralized platforms develop complementarily is expected to be a realistic direction.
3.3. Enterprise-education integration innovation scenario
The most practical and immediately applicable scenario is the complete integration of corporate talent development and education ecosystems. This means redesigning the entire HR process—recruitment, training, evaluation, promotion—on a blockchain-based foundation.
At the core of this scenario is the microlearning revolution centered on practical skills. Companies can deconstruct the specific skills and competencies they actually need into modular training programs and provide them via blockchain-based platforms. For example, Samsung Electronics could create highly specific courses such as “5G communication chipset design,” “battery efficiency optimization,” or “display color tuning,” offering these not only to its employees but also to supplier employees and even job seekers in related fields. Those who complete these programs would possess verified skills, making them immediately deployable.
The transparent tracking of learning outcomes within companies will fundamentally transform HR practices. Every individual’s learning activities, skill acquisition, project participation, and performance achievements would be recorded on the blockchain in real time, allowing promotions and rewards to be based on objective and transparent data. This improves fairness by reducing reliance on subjective or political evaluations and ensures that employees who truly contribute to the company receive appropriate recognition. For employees, it also provides clear evidence of their growth and contributions, helping them manage their careers.
The most revolutionary aspect of this system is the complete integration of recruitment and training. Instead of searching for “finished” talent, companies can select individuals with potential and develop them into the talent they need. For instance, if an IT company needs AI developers, it can select applicants with foundational math and programming skills, provide six months of intensive AI training, and make final hiring decisions based on learning outcomes and project performance. All of this would be transparently and fairly managed on the blockchain.
Personalized career development and reskilling will become increasingly important in a rapidly changing technological environment. AI can comprehensively analyze an employee’s current competencies, performance, interests, and the company’s future strategies to propose customized career development paths. For example, if a marketing employee expresses interest in data analysis, the system could suggest a roadmap to transition into a “digital marketing data analyst” role. Such personalized career development increases employee satisfaction and loyalty while simultaneously helping companies retain and develop talent.
Project-based learning and practical integration will be a key method for closing the gap between theory and practice. Educational programs would not rely on abstract theories but rather use real company challenges and projects as material, allowing learners to immediately apply what they learn. Project experiences and outcomes would be recorded on the blockchain, enabling individuals to prove their capabilities not with certificates but with actual work results.
The establishment of industry-specific skill standards will also be an important result of this enterprise-education integration system. Major companies in each industry can jointly define the core competencies needed in their fields and create standards for measuring and certifying them. For example, Hyundai Motor, Kia, and Samsung SDI could jointly establish a “battery expert for electric vehicles” certification program, enabling talent who acquire these skills to be recognized across the entire industry.
The formation of a global talent pool will be the long-term effect of this enterprise-education integration system. Educational programs offered by companies in different countries would be shared globally via blockchain, enabling anyone to receive top-level practical training regardless of location. For example, a young person in Korea could take an engine design course from a German car company, complete a quality management program from a Japanese company, and intern at a U.S. startup—all of which would be managed as a unified career record.
However, for such an enterprise-education integration system to succeed, protection of workers’ rights and fair distribution of opportunities must be carefully considered. There is a risk that companies might focus solely on cultivating talent tailored to their needs, limiting workers’ autonomy and diverse career choices. Therefore, it is essential to design a balanced system that guarantees individual choice and rights while harmonizing corporate and societal needs, utilizing blockchain’s transparency and decentralized characteristics.
These three scenarios are not mutually exclusive but rather likely to develop complementarily. The global university consortium can focus on foundational academic and research-oriented higher education, decentralized platforms can offer creative and innovative learning experiences, and enterprise-education integration systems can handle practical and immediately applicable skill development. Blockchain technology will serve as the infrastructure connecting these diverse educational models into a unified network, allowing learners to design optimal educational paths tailored to their goals and circumstances.
4. Technical implementation and user experience optimization
4.1. Applying complex blockchain technology to education
The biggest obstacle to blockchain-based educational innovation is the fear and resistance within the education sector toward technical complexity. Most educators and learners want to focus on the essence of education itself and have no desire to understand complicated technical concepts. In particular, education administrators in their 40s to 60s, who are the main decision-makers in educational institutions, may find concepts like blockchain, smart contracts, and digital wallets unfamiliar and intimidating.
To address this issue, designing intuitive and familiar user interfaces is crucial. Instead of seeing menus labeled “Blockchain-based grade entry,” educators should see terms like “Secure grade management” or “Tamper-proof certificate issuance.” Similarly, instead of “Check degree NFT in wallet,” students should simply click a straightforward button labeled “View my graduation certificate” to use all functions seamlessly.
The introduction of Wallet-as-a-Service (WaaS) is a key strategy for ensuring user-friendliness. In traditional blockchain systems, users had to manage their private keys and set up complex wallets themselves, but in the education sector, this complexity must be completely abstracted away. With WaaS, educational institutions or platform operators handle the complex parts of wallet management on behalf of the users, so they experience it as easily as using a regular website or app. When a student signs up, a blockchain wallet is automatically generated in the background, and all certificates and learning records are automatically stored in it, without the user ever having to be aware of the technical processes.
Integration with existing LMS (Learning Management Systems) is also critical for ensuring this user-friendliness. Rather than completely replacing familiar LMS interfaces and workflows (such as Moodle, Blackboard, Canvas), the more realistic approach is to maintain them while enhancing only the core verification and certification functions with blockchain. For example, when a professor enters grades into the LMS as usual, WaaS infrastructure can automatically encrypt and record the data on the blockchain in the background, with students simply seeing an additional “Blockchain verification complete” mark when checking their grades on the familiar screen.
Implementing social login and integrated authentication systems can further improve the WaaS user experience. By allowing users to log in with existing accounts like Google, Facebook, or Naver, blockchain wallets can be automatically linked, enabling access to all blockchain education services without complex account creation or key management processes. This offers a consistent experience, especially for modern learners who frequently move across different educational platforms.
However, simply hiding the technology is not enough. There also needs to be a systematic approach to improving blockchain literacy among educational stakeholders. While they don’t need to understand all technical details, it is important that they grasp the values and meanings of transparency, security, and decentralization that blockchain provides. Through the WaaS model, technical complexity is fully abstracted, but the benefits and significance must still be clearly communicated.
4.2. Supporting educational institutions in digital transformation
Just as important as optimizing user experience is supporting organizational and cultural changes in educational institutions. Many institutions are still accustomed to traditional paper-based systems and face-to-face workflows, so sudden digital transformation can cause significant resistance and confusion.
A gradual introduction strategy for traditional educational institutions is key to overcoming this. Rather than attempting to transition all systems to blockchain at once, it is more realistic to start with areas that can clearly demonstrate value. For example, in the first stage, institutions could adopt a simple WaaS-based digital graduation certificate system, allowing faculty to directly experience the benefits of blockchain. Existing workflows remain unchanged, with only the final step replaced by issuing a digital certificate instead of a paper one.
Once such initial successes accumulate, the second stage could involve adding blockchain verification to grade management systems, and the third stage could expand to admissions processes or scholarship management. At each stage, the WaaS advantage of minimizing operational burden is significant. Institutions do not need to build and manage complex blockchain infrastructure themselves; they can quickly and securely implement systems by utilizing service-based solutions.
During this gradual introduction, blockchain literacy training for faculty and staff is essential. However, this training should not focus on technical details but rather on the practical changes and benefits for the educational field. Messages like “WaaS handles complex technology so we can focus solely on teaching,” “No more worries about fake graduation certificates,” and “We can evaluate students’ learning achievements more accurately and fairly” are effective ways to communicate.
Ensuring compatibility with existing academic administration systems is one of the most technically and operationally challenging tasks. Most institutions have academic management systems developed by different vendors over decades, each with its own data structure and processes. The WaaS model greatly simplifies this integration challenge. Instead of each institution building and linking its own blockchain system, they can connect to a standardized WaaS API.
Presenting a cost-efficient implementation model is especially important for educational institutions with limited budgets. One of the biggest advantages of WaaS is its flexible, usage-based pricing structure. Institutions can use and pay only for the services they need without massive initial investments, significantly reducing financial burdens. Furthermore, a consortium model where multiple institutions jointly participate can further lower individual costs while maximizing network effects.
4.3. Building a global educational ecosystem
Beyond supporting individual institutional transformation, building a truly global educational ecosystem requires a much more comprehensive and holistic approach. This involves not only technical interoperability but also reconciling legal, cultural, and economic differences through international cooperation.
Establishing cooperative frameworks among educational institutions in different countries is the foundation for such a global ecosystem. Currently, each country's ministry of education or accreditation body operates its own academic recognition system independently. By connecting these systems through a blockchain-based integrated network, such fragmentation can be resolved. The WaaS model can greatly promote this international cooperation. Instead of each country building and negotiating technically complex blockchain systems for interoperability, jointly utilizing a standardized WaaS platform is much more efficient.
For example, if educational institutions in Korea, the US, and Germany all use the same WaaS platform, differences in degree systems and curricula can be automatically mapped and converted at the platform level. The relationship between Korea’s four-year bachelor’s degree, the US bachelor's degree, and Germany’s bachelor’s degree would be predefined in the system, allowing automatic academic recognition when students move between countries.
Ensuring global standardization and interoperability is the technological foundation for this global ecosystem. With the WaaS model, standardization at the platform level naturally occurs. Since all participating institutions use the same platform and protocols, full interoperability can be achieved without separate complex negotiations. Data formats, security requirements, privacy policies, and governance structures are all uniformly managed at the platform level.
In terms of economic sustainability and business model innovation, WaaS offers cost efficiency through economies of scale. As numerous educational institutions worldwide share a single platform, the individual cost burden is greatly reduced while enabling more advanced services. Additionally, the network effect allows all participants to benefit more as more institutions join, creating a virtuous cycle.
Cooperation with international organizations and policy coordination is another strength of the WaaS model. Organizations like UNESCO and OECD can more efficiently collect and analyze global educational data via standardized WaaS platforms, enabling more precise and rapid policy formulation and improvement recommendations.
Ultimately, a WaaS-based global educational ecosystem presents an ideal model where technical complexity is managed by experts, and educators and learners can focus solely on the true purpose of education. It allows access to high-quality blockchain education services anywhere in the world, regardless of language, culture, or economic conditions, providing a foundation for true educational democratization.
5. Challenges and future prospects
As blockchain-based education systems mature, the most critical challenge is solving issues of the digital divide and accessibility. No matter how innovative a technology is, if only certain groups can access it, it risks worsening educational inequality. The WaaS model offers a realistic solution to this dilemma. By using cloud-based services, high-quality blockchain education services can be experienced even without high-performance hardware. Additionally, through subscription-based models, individuals can access the latest educational technologies without large upfront costs, thus achieving both technological innovation and expanded educational access.
However, resolving accessibility issues does not mean everything is solved. There remains the more fundamental challenge of balancing privacy protection with data utilization. The more detailed the educational data recorded on the blockchain, the greater the personalization effect, but at the same time, the risk of privacy infringement also increases. To resolve this paradox, the WaaS model offers advanced cryptographic technologies such as differential privacy and homomorphic encryption as standard services. These allow for complete protection of individuals’ original data while enabling group-level pattern analysis to improve learning outcomes, thus striking a sophisticated balance.
For these technical solutions to bring meaningful change in society, policy support is essential. Addressing educational inequality and expanding accessibility cannot be achieved by market logic alone and requires active public sector involvement. The greatest social value of the WaaS model lies in equalizing access to technology. By providing advanced educational technology as a service, which traditionally only universities and large corporations could build, it significantly reduces limitations related to economic resources or geographic location. However, realizing this potential requires government support and public policy backing.
Such public support should not be limited to simple financial subsidies but should be linked to a larger vision of transitioning to a lifelong learning society. In an era of rapidly changing technologies, one-time education has clear limitations, and continuous learning and reskilling have become not only a personal survival strategy but also a prerequisite for social development. The WaaS model can serve as an effective tool to implement such policy goals. By integrating and managing various government-led reskilling, vocational training, and lifelong learning programs on the WaaS platform, program efficiency can be improved, redundancy reduced, and individuals’ learning histories consistently managed.
However, as such integrated management becomes possible, the issue of educational data governance also emerges as a new challenge. When individuals’ detailed learning data is concentrated on a single platform, the risk of misuse increases accordingly. The WaaS model has the advantage of applying standardized data governance policies at the platform level, greatly reducing compliance costs and enhancing policy effectiveness. At the same time, it must provide tools that allow individuals to set and control their data permissions in detail, thus offsetting the risks of centralization.
Even if these domestic challenges are addressed, there still remains the global-level challenge of international cooperation and standardization. The true value of blockchain educational innovation can only be fully realized when cross-border learning and certification become possible. The WaaS model can play a significant role in promoting such international cooperation. Instead of each country independently building complex blockchain education systems and negotiating interoperability, adopting a common WaaS platform simplifies and accelerates international cooperation. This facilitates not only technical standardization but also policy coordination, laying the groundwork for building global educational governance.
When we consider all these changes together, it becomes clear that the educational innovation brought by blockchain and WaaS represents a fundamental paradigm shift beyond mere technological progress. The monopoly of centralized educational institutions will be dismantled, a learner-centered lifelong learning ecosystem will be established, and a fair evaluation system based on actual capabilities will be put in place. The WaaS model will be the key driver of this transformation, providing an ideal structure where technical complexity is managed by experts and educators and learners can focus on the true purpose of education.
Ultimately, for this educational innovation to succeed, continuous cooperation among technology developers, educators, policymakers, and civil society is essential. Balancing technological innovation, social value, economic sustainability, and ethical responsibility cannot be achieved by any single party alone. However, if these challenging tasks are successfully addressed, we will be able to build a learning environment where everyone can fully realize their potential. This will not be about technology replacing humans, but rather about augmenting human capabilities — a true human-centered educational revolution.
