            <abstract>
                <p>The high-speed growth of intra-African trade, especially after the signing of the African Continental Free Trade Area (AfCFTA) agreement has highlighted the necessity of a more efficient and transparent system of cross-border logistics. Blockchain technology is a potential solution to solve the longstanding problems of African trade logistics such as fraud, inefficiencies, delays, and high transaction costs (
                    <xref ref-type="bibr" rid="ref11">M&#x00fc;ller et al., 2020</xref>). This is a systematic literature review of opportunities to implement blockchain in cross-border logistics in Africa and how it is likely to increase the level of supply chain transparency, traceability, and efficiency. Systematic identification 134 studies that were published between 2018 and 2025 and analyzed in relation to PRISMA priorities (
                    <xref ref-type="bibr" rid="ref6">Liberati et al., 2009</xref>). The review finds essential blockchain applications, such as smart contract applications, real-time monitoring, and decentralized documentation, to enhance logistics procedures in cross-border trade in Africa (
                    <xref ref-type="bibr" rid="ref22">Zhao et al., 2021</xref>). Although blockchain seems promising, the review also identifies key obstacles to its usage, such as insufficient digital infrastructure, regulatory issues, and technical capacity (
                    <xref ref-type="bibr" rid="ref7">Makhija et al., 2022</xref>). The results indicate that blockchain has the potential to significantly enhance cross-border logistics, but its implementation should be coordinated by African governments, technology creators, and logistics stakeholders (

            <title>Introduction</title>
            <p>Nonetheless, in recent years, there has been a sharp increase in intra-regional trade in Africa, with much of it benefiting the adoption of the African Continental Free Trade Agreement (AfCFTA), which seeks to advance economic integration in the continent (
                <xref ref-type="bibr" rid="ref20">UNECA, 2020</xref>). Nevertheless, even with this positive trend, cross-border logistics in Africa are still burdened by inefficient customs procedures, inability to be transparent, fraud, and excessive transaction costs (
                <xref ref-type="bibr" rid="ref11">M&#x00fc;ller et al., 2020</xref>).</p>
            <p>Such inefficiencies not only slow down trade but also discourage investment, restricting the region from exploiting its increasing trade opportunities. To solve these bottlenecks, it is necessary to consider new technological ways of solving the problem, which may improve the process of logistics and make the process of trade easier and more dependable. Among the technologies that have received much publicity is blockchain, a decentralized system of ledgers, which is characterized by the possibility of ensuring safe, transparent, and impeccable documents of transactions (
                <xref ref-type="bibr" rid="ref22">Zhao et al., 2021</xref>). Originally introduced through its application in the cryptocurrency industry, blockchain has proven to have enormous prospects for transforming other sectors, such as finance, health, and logistics (
                <xref ref-type="bibr" rid="ref7">Makhija et al., 2022</xref>).</p>
            <p>Blockchain was set to tackle most of the ancient issues in international commerce by enhancing transparency, traceability, and efficiency throughout the supply chains in the logistics sector (
                <xref ref-type="bibr" rid="ref12">Nguyen and Lee, 2023</xref>). As an illustration, blockchain can be useful in real-time tracking of shipments, automating custom documents, and mitigating fraud, which are all essential for facilitating the cross-border trade process (
                <xref ref-type="bibr" rid="ref22">Zhao et al., 2021</xref>). In Africa, the possible advantages of blockchain in the logistics field are very high because of the need for better supply chain management and facilitation of trade in the region (
                <xref ref-type="bibr" rid="ref11">M&#x00fc;ller et al., 2020</xref>).</p>
            <p>Several African nations have started testing blockchain-based systems to facilitate their trade activities, better documentation, and increased stakeholder confidence. Nevertheless, blockchain implementation in African logistics is associated with the following barriers: infrastructure, regulations, and low technical capacity (
                <xref ref-type="bibr" rid="ref7">Makhija et al., 2022</xref>). Regardless of these barriers, blockchain in cross-border logistics can revolutionize African trade by increasing trade efficiency, meeting trade regulations, and lowering costs.</p>
            <p>This systematic literature review will determine the potential of blockchain technology to enhance cross-border logistics in Africa with regard to its usage, advantages, adoption challenges, and prospects of its scalability to the continent.</p>

                <title>Search strategy</title>
                <p>The systematic search was carried out in two large academic databases, PubMed and IEEE XPLORE, because they provided more technological knowledge on the topic of interest. The search area was limited to the literature published between 2018 and 2025, and all the studies included in the review had to be written in English. The search terms and Boolean strings that were employed to obtain a complete set of relevant studies were as follows: blockchain logistics, blockchain cross-border logistics in IEEE EXPLORE, and blockchain and traceability supply chain in the PubMed database. These keywords specifically focused on studies that have touched on blockchain technology in the context of African cross-border logistics, trade facilitation, and supply chain enhancements. A reference management tool was used to examine the results of the database.</p>

                <p>A standardized quality assessment instrument was used to assess the quality of the included studies to determine the rigor of the research methods used. This move was meant to ensure that only studies of reasonable quality in terms of methodology were included in the review. The evaluation criteria included the appropriateness of the study design, in which the appropriateness of the study design for answering the research questions was evaluated. This would involve an assessment of whether it was an empirical study, case study, or review, and whether the design was suitable to achieve the research aims.</p>
                <p>Methodological transparency was also tested, where the research methods were designed to exert clarity and reproducibility. This involved determining whether the study presented a clear description of the methodology, such that it could be reproduced by other people. The reliability and validity of the study findings were also checked, and this consisted of whether the data employed were reliable and valid, and whether the right analytical procedures were used to justify the findings.</p>
                <p>Finally, research interest in the African setting of blockchain applications in interstate trade was tested. The study was evaluated in terms of its applicability to African logistics and the solutions to problems particular to the region.</p>

                <title>Data analysis</title>
                <p>The study of blockchain technology as a method of improving cross-border logistics in Africa was conducted as a systematic review (including 134 studies published between 2018-2025). Research papers were systematically selected using PubMed and IEEE Xplore databases in accordance with PRISMA (
                    <xref ref-type="bibr" rid="ref6">Liberati et al., 2009</xref>). The major results of the reviewed studies indicate that blockchain technology has a wide range of applications, such as smart contacts, real-time tracking, and decentralized documentation (
                    <xref ref-type="bibr" rid="ref22">Zhao et al., 2021</xref>).</p>
                <p>Another major trend that the review identified is the blockchain&#x2019;s promise of improving transparency and traceability. A few studies describe the capability of blockchain to enhance the accuracy of data, minimize delays, and automatize documentation, which are essential for effective cross-border trading. Nevertheless, this review also identified significant adoption challenges. The main issues are the low level of digital infrastructure, regulatory problems, and technical capacity of African countries (
                    <xref ref-type="bibr" rid="ref7">Makhija et al., 2022</xref>).</p>
                <p>Interestingly, research indicates that blockchain can bring considerable improvements to the operations of the supply chain, notably the industries of agriculture, pharmaceuticals, and e-commerce (
                    <xref ref-type="bibr" rid="ref12">Nguyen and Lee, 2023</xref>; 
                    <xref ref-type="bibr" rid="ref4">Kalkha et al., 2023</xref>). An example of smart logistics with e-commerce using blockchain has demonstrated that a combination of blockchain and technologies such as IoT, AI, and cloud computing could make the supply chain more efficient and competitive (
                    <xref ref-type="bibr" rid="ref4">Kalkha et al., 2023</xref>). However, despite its high potential, the adoption of blockchain in African logistics is associated with complicated challenges. These include the absence of government and industry cooperation and the inability to have a standard regulatory system to implement blockchain within the continent.</p>

            <title>Discussions</title>
            <p>The introduction of blockchain technology in cross-border logistics in Africa presents a rare opportunity to solve most long-term logistical problems faced by the region has been facing. The African Continental Free Trade Area (AfCFTA) agreement has facilitated a swift transformation in the intra-African trade environment, yet ineffective customs processes, absence of transparency, fraud, and high transaction costs are factors that prevent growth and investment (
                <xref ref-type="bibr" rid="ref11">M&#x00fc;ller et al., 2020</xref>). Blockchain technology and its decentralization, impossibility, and transparency attributes can offer an effective solution to many of these struggles.</p>
            <sec id="sec11">
                <title>The impact of blockchain on improving the traceability and transparency</title>
                <p>Among the most prominent benefits of blockchain technology is its capability to provide transparent and unreliable transaction documents. This would go a long way to improving the visibility of the supply chain with reference to African cross-border logistics. Real-time shipping tracking can be conducted with the help of blockchain, and all stakeholders, including customs, importers, exporters, and logistics companies, can monitor the flow of goods along the supply chain (
                    <xref ref-type="bibr" rid="ref22">Zhao et al., 2021</xref>). Such increased visibility not only minimizes the chances of lost or stolen goods but also allows a quicker response in cases of discrepancy or delay.</p>
                <p>In addition, decentralized documentation using blockchain is important, particularly in Africa, where fraud is prevalent. Blockchain ensures that documents are not manipulated by providing a system in which documents such as bills of lading, invoices, and certificates of origin are stored in a decentralized and safe place. This will significantly decrease corruption and counterfeit, as is common in the African trade (
                    <xref ref-type="bibr" rid="ref7">Makhija et al., 2022</xref>). Consequently, blockchain might enhance the trust of stakeholders, minimize the intermediation process, and shorten the trade process.</p>

                <title>Eliminating delays and transaction costs</title>
                <p>Another important advantage of blockchain in&#x2019;srica the logistics is the efficiency gains linked to it. Traditional supply chain systems have been marked with manual processes, paperwork, and the absence of integration of various players in the trade process. Such inefficiencies add to the prolonged time consumers spend on the border points, leading to high transaction costs and decreased competitiveness of African trade in general. Automation of procedures such as customs clearance, payment of taxes, and smart contracts can facilitate the process using blockchain technology. Smart contracts are programmed to conduct and verify transactions under predetermined conditions, and they do not require the involvement of intermediaries, which ensures less time spent on transactions (
                    <xref ref-type="bibr" rid="ref22">Zhao et al., 2021</xref>).</p>
                <p>Within the framework of customs procedures, blockchain has the potential to facilitate automated compliance checks, which would accelerate the process of moving the border, decrease the number of backlogs, and eventually decrease transaction costs of transactions (
                    <xref ref-type="bibr" rid="ref12">Nguyen and Lee, 2023</xref>). It is especially significant that in Africa, there have been many losses in business due to the delay at border crossings, which makes the region less appealing as a trading partner.</p>

                <title>The obstacles to the use of blockchain in Africa</title>
                <p>Although the adoption of blockchain in African cross-border logistics has potential advantages, it has a number of barriers. Infrastructure challenges are also significant problems. African nations do not have the digital infrastructure required to execute and accommodate blockchain systems, which include fast Internet access, consistent power supply, and data storage capacity (
                    <xref ref-type="bibr" rid="ref7">Makhija et al., 2022</xref>). Such shortcomings in infrastructure have the potential to negatively affect the successful implementation of blockchain solutions, particularly in rural and underdeveloped countries.</p>
                <p>In addition, the fact that numerous African nations do not have regulatory structures contributes to an increased level of complexity. The lack of legal guidelines that can be put in place to provide a clear and standardized approach to the use of blockchain in logistics may lead to uncertainty among stakeholders such as governments, logistics providers, and trade organizations. The possibility of blockchain guaranteeing data safety and privacy is also not incidental, as most African nations do not have legal regulations that guarantee the safety and privacy of data and the implementation of intellectual property rights in a virtual space (
                    <xref ref-type="bibr" rid="ref11">M&#x00fc;ller et al., 2020</xref>).</p>
                <p>Another key obstacle is the poor technical capabilities of most African countries. Although blockchain technology has proven itself capable in the developed world, the lack of qualified personnel and local capacity building programs may retard the use of blockchain-based systems in Africa. Africa could face the problem of a lack of a sufficient number of trained personnel to develop and operate blockchain as well as to maintain these systems (
                    <xref ref-type="bibr" rid="ref7">Makhija et al., 2022</xref>).</p>
            </sec>
            <sec id="sec14">
                <title>The way forward: removing obstacles</title>
                <p>To overcome these obstacles, close collaboration among African governments, technology developers, and logistics players is very important. Digital infrastructure should be heavily invested to allow the extensive implementation of blockchain technology. This may involve the inclusion of partnerships between the government and business fraternity and international partnerships to enhance connectivity and amplify digital networks in the continent.</p>
                <p>Regulation systems should be established and streamlined at the national level to facilitate smooth adoption of blockchain technology. Establishing a common solution to regulate blockchain will enable African nations to gain trust in stakeholders and promote cross-border cooperation. Finally, capacity-building should also be targeted so that African professionals will have the required skills to handle and apply blockchain systems. This may be done through training courses, university relationships, and partnerships with international organizations concerned with technical education.</p>

                <title>Recommendations</title>
                <p>

                    <bold>Develop digital infrastructure</bold>
                </p>
                <p>The absence of a strong digital infrastructure is a major obstacle to effective blockchain implementation in Africa. African governments need to invest in Internet connectivity, high data transmission speed, and consistent electricity to adopt blockchain in cross-border logistics. This is particularly imperative in rural setups where the digital divide is the sharpest.</p>
                <p>Data centers and cloud storage facilities must be created or enlarged to process a large amount of data created by blockchain applications besides the Internet infrastructure. Governments are expected to coordinate efforts with international partners, development bodies, and the private sector to finance and execute large infrastructure projects. One model that may be useful in facilitating such investments in the public-private partnerships (PPPs). Additionally, other initiatives such as the Digital Transformation Strategy of Africa by the African Union could be used to ensure that African nations develop their digital infrastructure to facilitate efficient logistics systems across the border.</p>
                <p>

                    <bold>Create blockchain regulatory regimes</bold>
                </p>
                <p>A key impediment in Africa is the absence of definite regulatory frameworks for blockchain adoption. To overcome this, African governments need to develop special policies of blockchain technology in logistics. This involves the establishment of data privacy, cybersecurity, and smart contract enforcement standards. In addition, the regulatory framework must make blockchain systems interoperable in various African countries to enable cross-border trade.</p>
                <p>A pan-African model of blockchain regulation may be created based on the experience of regional projects, such as the African Continental Free Trade Area (AfCFTA). Regional organizations such as East African Community (EAC) and Economic Community of West African States (ECOWAS) may be instrumental in the harmonization of blockchain regulations and cross-border collaboration. This provides a limited regulatory environment that is predictable and less uncertain to stakeholders in logistics, trade, and supply management.</p>
                <p>

                    <bold>Introduce national strategies of adoption of blockchains</bold>
                </p>
                <p>Since African countries have their own unique challenges, it is important that each government develop a national blockchain adoption strategy that considers local conditions. The strategies must revolve around the identification of key industries in which blockchain can be applied (e.g., agriculture, pharmaceuticals, and e-commerce), local expertise development, and pilot projects to test blockchain solutions in the real-world context.</p>
                <p>For example, countries that have established strong agricultural export markets, including Kenya (in the horticulture industry) and Ghana (in the cocoa industry), can build blockchain-based traceability solutions to verify the quality and safety of exports and promote transparency in supply chains. Scalability should also be a national concern, in which blockchain systems can be expanded and adapted with an increase in trade volumes and technological capacity.</p>
                <p>

                    <bold>Emphasize capacity development and technical training</bold>
                </p>
                <p>Effective implementation of blockchain technology in Africa requires an experienced workforce that can design, sustain, and optimize blockchain systems. The capacity-building programs that should be invested in by governments, academic institutions, and private sector companies should focus on training young professionals on the technical skills that would allow them to implement blockchain solutions.</p>
                <p>Schools and colleges must employ courses on blockchain applications at different levels, including vocational education and university degrees, and develop blockchain technology and smart contract development certification programs. Moreover, training workshops and internship programs may be sponsored by public collaborations, which offer hands-on experience in blockchain usage and implementation, particularly in the fields of logistics and supply chain management. This would serve to create a workforce that can handle the requirements of the emerging African blockchain sector.</p>
                <p>

                    <bold>Promote innovation and cooperation in the private sector</bold>
                </p>
                <p>To ensure the success of blockchain adoption, it is necessary to establish government entities, logistics companies, trade associations, and technology-creating firms. African trade logistics within the scope of the private market should be addressed by encouraging the development of innovative solutions by logistics companies, fintech firms, and blockchain start-ups.</p>
                <p>Governments need to encourage blockchain start-ups to access funding opportunities by giving them innovation grants, tax incentives, and access to blockchain-based logistics solutions. In addition, consortia of the private sector must be invited to develop blockchain systems that can be utilized across several industries (e.g., agriculture, pharmaceuticals, and e-commerce), and therefore, less fragmentation and a greater ability to scale. Blockchain consortia in specific industries would also enable the standardization of blockchain protocols and make them interoperable across industries.</p>
                <p>

                    <bold>Pilot projects should be implemented to prove the value of blockchain</bold>
                </p>
                <p>Pilot projects are essential for comprehending the practice of blockchain applications in the real world and testing their scalability in other settings. Governments and industry players must work together to implement pilot projects that can illustrate the potential of blockchain in international logistics. For example, a pilot project may be developed to investigate blockchain-based solutions to automate customs or to perform automated tracking of the supply chain in busy trade locations such as Mombasa (Kenya) and Durban (South Africa).</p>
                <p>The pilot projects are supposed to be structured to test the cost-efficiency of blockchain, its effect on efficiency, the decrease in fraud, and the enhancement of trade. In addition, pilot projects will provide the prospect of detecting technical and regulatory barriers before large-scale use. Once successful, these pilots may be used as a demonstration of the concept and to provide significant information on how blockchain can be extended to the continent.</p>

                <title>Encourage global cooperation and exchange of information</title>
                <p>Blockchain technology is universal, and most lessons obtained in other parts of the world can be transferred to the logistics sphere in Africa. Hence, African governments and industry players must aggressively adopt international partnerships to understand how developed nations and other regional blockchain projects perform.</p>
                <p>Participation in international blockchain consortia and forums, including the International Chamber of Commerce (ICC) and the Blockchain for Supply Chain Global Initiative, may be advantageous to Africa. Through partnerships with international organizations and technology players, African nations may have access to state-of-the-art solutions, capital, and knowledge that may hasten blockchain implementation in logistics.</p>

                <title>Dwelling on sustainable trade with blockchain</title>
                <p>The use of blockchain technology to enable sustainable trade should also be prioritized in African countries, in line with the UN Sustainable Development Goals (SDGs). The tracing functionality of the blockchain can be used to guarantee ethical sourcing and environmental responsibility. For example, sustainable sourcing of cocoa, coffee, and timber can be ensured using blockchain in sectors that are important to a few African economies.</p>
                <p>With the introduction of sustainability in blockchain applications, Africa can improve its image as a destination that upholds ethical trading and sustainable development. African countries may also find it easier to adhere to international trading regulations on the environment and social standards with the help of blockchain and a rise in rank within global supply chains.</p>

            <title>Conclusions</title>
            <p>This literature review has explored how the blockchain technology can be used to improve cross-border logistics in Africa, especially the African Continental Free Trade Agreement African Continental Free Trade Agreement (AfCFTA). The review is a synthesis of the important results of 138 articles published between 2018 and 2025, which estimated the uses of blockchain, advantages, and limitations of its introduction in African trading logistics.</p>
            <p>The results of this review emphasize the fact that blockchain technology has great potential to revolutionize trade in Africa by solving the traditional logistics problems of cross-border trade, namely inefficiency, delays, fraud, and high transaction costs. The main characteristics of blockchain&#x2013;transparency, immutability, and decentralization&#x2013;provide workable solutions to make the process of supply chain traceability more effective, make the process of customization more efficient, and documentation enhancement. These gains may lead to smoother trade, less corruption, and increased credence of stakeholders, thus allowing economic integration in Africa, particularly with AfCFTA in office.</p>
            <p>Nevertheless, the implementation of blockchain technology in the cross-border logistics industry in Africa has serious weaknesses, notwithstanding its potential. Still, the most significant barrier to the mass adoption of blockchains is infrastructure shortages, including unstable Internet and power supply, and legal loopholes, including the absence of definite legal frameworks. Moreover, the technical capacity in most African nations is insufficient, and it is challenging to establish, deploy, and sustain blockchain systems.</p>
            <p>The only way to eliminate these barriers is through joint efforts by government, technology developers, and logistics stakeholders. The urgent need is the investment in digital infrastructure, the creation of regulatory standards, and the growth of technical expertise in blockchain technologies. Through these concerns, Africa will have the ability to make the most of the blockchain to enhance efficiency, transparency, and traceability in the logistics business, thus leading to effective and more dependable intra-African trade.</p>
            <p>Finally, although blockchain technology presents a transformative opportunity to improve the logistics of cross-border operations in Africa, implementation of the technology will have to be done in a coordinated and strategic manner that will target the infrastructural, regulatory, and capacity-related barriers highlighted in this review. When such challenges are tackled, blockchain plays a major role in minimizing trade barriers, enhancing supply chains, and achieving the long-term objective of economic integration within the continent.</p>
            <p>Empirical case studies, pilot projects, and policy recommendations examining the practical use of blockchain in African logistics should be considered in future research. The lessons learned during these initiatives will be essential in making blockchain live up to its hype as a means of making trade in Africa more transparent, efficient, and sustainable.</p>

        <body>
            <p>This manuscript presents a timely and highly relevant systematic review of blockchain's potential to enhance cross-border logistics in Africa, particularly in the context of the AfCFTA agreement. However, significant methodological inconsistencies specifically regarding the final sample size of included studies and structural gaps undermine its current validity, necessitating a 
                <bold>major revision</bold> before it can be considered for indexing.</p>
            <p> &gt;Reconcile the glaring discrepancy in the number of included studies; the abstract claims 134 studies were analyzed , and the conclusion states 138 , yet the PRISMA flow diagram explicitly shows only 6 studies were included in the final review.</p>
            <p> &gt;Explicitly define the specific research gap in the introduction, clarifying what previous reviews on African logistics lack and why this updated synthesis is critical right now.</p>
            <p> &gt;Introduce a dedicated "Literature Review" section prior to the methodology to properly establish the theoretical background of blockchain architecture and its existing applications in global supply chains.</p>
            <p> &gt;Expand the discussion to critically synthesize the findings of the included studies, rather than merely listing general blockchain benefits and barriers.</p>
            <p> &gt;Consolidate the current "Recommendations" into a formally demarcated "Managerial and Policy Implications" section to provide actionable, structured guidance for logistics practitioners and policymakers.</p>
            <p> &gt;Ensure the conclusion aligns accurately with the data actually analyzed in the study, and summarize the precise contributions to the existing body of knowledge on supply chain transparency and African trade.</p>
            <p> &gt;To strengthen the discussion around blockchain adoption barriers, logistics optimization, and digital transformation in supply chains, consider citing the following highly appropriate articles from the broader literature:</p>
            <p> -Exploring the critical drivers of blockchain technology adoption in Indian industries using the best-worst method. International Journal of Productivity and Performance Management.</p>
            <p> -&#x00a0;Enhancing freight logistics: overcoming barriers and driving sustainable growth with an integrated grey Delphi DEMATEL approach. Benchmarking: An International Journal.&#x00a0;</p>
            <p> -Enabling supply chain viability through digital transformation: Analysis of barriers in Industry 4.0 context. Journal of Digital Economy.</p>
            <p>Are the rationale for, and objectives of, the Systematic Review clearly stated?</p>
            <p>Partly</p>
            <p>Is the statistical analysis and its interpretation appropriate?</p>
            <p>Not applicable</p>
            <p>If this is a Living Systematic Review, is the &#x2018;living&#x2019; method appropriate and is the search schedule clearly defined and justified? (&#x2018;Living Systematic Review&#x2019; or a variation of this term should be included in the title.)</p>
            <p>Not applicable</p>
            <p>Are sufficient details of the methods and analysis provided to allow replication by others?</p>
            <p>Partly</p>
            <p>Are the conclusions drawn adequately supported by the results presented in the review?</p>
            <p>Partly</p>
            <p>Reviewer Expertise:</p>

            <p>I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard, however I have significant reservations, as outlined above.</p>

            <p> </p>
            <p> 1. Summary of the Article</p>
            <p> The manuscript examines how blockchain technology could be used in African cross-border logistics. It places the discussion within the context of the African Continental Free Trade Area and argues that blockchain might help address customs delays, weak traceability, document fraud, poor shipment visibility, and high transaction costs.&#x00a0;The authors report a search of PubMed and IEEE Xplore for studies published between 2018 and 2025. The PRISMA diagram records 134 identified records, 51 screened records, 22 reports assessed for eligibility, and 6 studies included in the final review. Table 1 then summarizes studies on coordinated border management, supply chain visibility, e-commerce logistics, food traceability, and pharmaceutical traceability.</p>
            <p> </p>
            <p> The paper concludes that blockchain may offer value through smart contracts, decentralized documentation, real-time tracking, and traceability systems. It also notes several barriers that appear especially relevant in African logistics settings: weak digital infrastructure, fragmented regulation, limited technical skills, and the need for coordination between public agencies, technology providers, and logistics actors.</p>
            <p> </p>
            <p> 2. Overall Assessment</p>
            <p> The topic is timely and suitable for a journal audience interested in logistics, supply chain management, trade facilitation, and African regional integration. The manuscript identifies several relevant themes, and the practical orientation of the recommendations is useful.</p>
            <p> At this stage, however, the paper reads more like a narrative overview than a fully reproducible systematic review. The methodological trail is thin. The evidence base is also unclear because the manuscript refers to 134 records, 6 included studies, and later 138 synthesized articles. That inconsistency is not a minor editing issue. It affects the reader&#x2019;s ability to judge what evidence was actually reviewed.</p>
            <p> </p>
            <p> The manuscript could become indexed after substantial revision, but its present form does not yet support some of its broader claims about the likely effects of blockchain on African trade logistics.</p>
            <p> </p>
            <p> 3. Detailed Review</p>
            <p> </p>
            <p> 3.1 Rationale and Research Gap</p>
            <p> Assessment: Partly satisfactory.</p>
            <p> </p>
            <p> The rationale is plausible. African cross-border logistics do face delays, documentation burdens, and trust problems, and the link with AfCFTA gives the review a clear policy setting. Still, the research gap is underdeveloped. The authors do not show what previous blockchain or supply chain reviews have already established, nor do they explain what an Africa-focused review adds beyond a broad regional framing.</p>
            <p> </p>
            <p> Required revision: Add two or three explicit review questions. For instance, the review could ask which blockchain applications have been studied in African cross-border logistics, what benefits have been reported for customs efficiency and traceability, and which technical or regulatory barriers limit adoption.</p>
            <p> </p>
            <p> 3.2 Methods and Reproducibility</p>
            <p> Assessment: Not satisfactory.</p>
            <p> </p>
            <p> The search strategy cannot be reproduced from the information provided. The manuscript names PubMed and IEEE Xplore and lists broad search terms, but it does not provide complete database-specific search strings, search dates, field tags, Boolean operators, filters, or screening procedures. PubMed also seems too narrow for a topic that mainly belongs to logistics, trade, business, information systems, and supply chain research.</p>
            <p> </p>
            <p> Required revision: Provide full search strings for each database, the exact search date, the screening software or process used, the number of reviewers involved at each stage, and the method for resolving disagreements. The authors should also consider Scopus, Web of Science, ScienceDirect, Emerald, Taylor &amp; Francis, SpringerLink, ABI/INFORM, and a carefully documented Google Scholar search.</p>
            <p> </p>
            <p> 3.3 PRISMA Reporting</p>
            <p> Assessment: Partly satisfactory.</p>
            <p> Including a PRISMA flow diagram is a useful start. The problem is internal consistency. The paper reports 134 records in the abstract and methods, 6 final studies in the PRISMA diagram, and 138 articles in the conclusion. These numbers cannot all be correct.</p>
            <p> </p>
            <p> Required revision: Correct the study count everywhere: abstract, methods, PRISMA figure, results, discussion, conclusion, and data availability statement. If only 6 studies were included, the claims and synthesis should be scaled to that evidence base.</p>
            <p> </p>
            <p> 3.4 Eligibility Criteria</p>
            <p> Assessment: Partly satisfactory.</p>
            <p> </p>
            <p> The inclusion criteria mention date range, peer review status, English language, blockchain, supply chains, logistics, trade facilitation, and African relevance. This is a useful base, but the criteria remain too loose. The phrase &#x201c;African aspect&#x201d; needs a precise definition. A paper on general pharmaceutical traceability, for example, should not be included unless the authors can show a direct link to African trade, border logistics, or regional supply chains.</p>
            <p> </p>
            <p> Required revision: Define the context, technology, outcomes, and eligible study designs. The authors should state whether conceptual papers, case studies, reviews, policy reports, and empirical studies are all eligible. They should also justify the inclusion of each study in Table 1.</p>
            <p> </p>
            <p> 3.5 Quality Assessment</p>
            <p> Assessment: Not satisfactory.</p>
            <p> </p>
            <p> The manuscript says that a standardized quality assessment instrument was used, but the tool is not named and no results are shown. There is no appraisal table, no risk-of-bias judgment, no score, and no explanation of how study quality shaped the synthesis.</p>
            <p> </p>
            <p> Required revision: Add a quality appraisal table. Depending on the included study types, the authors could use MMAT, CASP, JBI, ROBIS, or a clearly justified custom checklist. Each included study should receive a transparent judgment, and weak evidence should not be treated as equal to stronger empirical work.</p>
            <p> </p>
            <p> 3.6 Data Extraction</p>
            <p> Assessment: Partly satisfactory.</p>
            <p> </p>
            <p> The authors state that three researchers extracted data, which is encouraging. Yet the extraction process is still hard to audit. The template, coding rules, checking process, and disagreement procedure are not described.</p>
            <p> </p>
            <p> Required revision: Add a data extraction template or supplementary table with author, year, country, sector, study design, database source, blockchain application, logistics function, reported benefit, barrier, limitation, and relevance to African cross-border logistics.</p>
            <p> </p>
            <p> 3.7 Results and Synthesis</p>
            <p> Assessment: Not satisfactory.</p>
            <p> </p>
            <p> The results are mainly descriptive. The discussion lists broad themes such as smart contracts, tracking, decentralized documentation, transparency, traceability, and infrastructure barriers, but it does not compare evidence across studies in a systematic way. At times, conceptual claims appear to be treated as if they were empirical findings.</p>
            <p> </p>
            <p> Required revision: Rebuild the results around structured synthesis. A thematic table would help. So would a sector-based synthesis covering customs, agriculture, pharmaceuticals, e-commerce, food supply chains, and trade corridors. Where possible, the authors should map evidence by country or region and identify whether each claim comes from empirical evidence, a case study, a review, or a conceptual argument.</p>
            <p> </p>
            <p> 3.8 Conclusions</p>
            <p> Assessment: Partly satisfactory.</p>
            <p> </p>
            <p> The conclusions broadly match the discussion, especially on infrastructure, regulation, and capacity constraints. The tone, however, is too certain for the evidence presented. If the final synthesis rests on 6 studies, phrases suggesting that blockchain will transform or significantly reduce corruption should be softened.</p>

            <p> Required revision: Use more cautious wording. For example, &#x201c;blockchain may support selected improvements in documentation, traceability, and stakeholder trust&#x201d; is more defensible than &#x201c;blockchain can revolutionize African trade.&#x201d; Similarly, &#x201c;blockchain may reduce opportunities for document manipulation&#x201d; is safer than claiming that it will significantly decrease corruption.</p>

                </list> 6. Suggested Revision Structure</p>
            <p> A stronger version of the manuscript could follow this order: Introduction with a sharper research gap and review questions; Methods with protocol details, databases, search strings, eligibility rules, screening process, extraction process, and appraisal tool; Results with study selection, study characteristics, quality appraisal, thematic synthesis, sectoral synthesis, and regional patterns; Discussion with interpretation, comparison with prior literature, limitations, and implications; Recommendations separated from evidence-based findings; and a conclusion written in cautious language.</p>
            <p> </p>
            <p> 7. Final Recommendation</p>
            <p> Major revision. The manuscript addresses a worthwhile question, but it is not yet methodologically secure enough to be accepted as a systematic review. The authors should correct the numerical inconsistencies, make the search reproducible, clarify eligibility, present quality appraisal results, and replace broad assertions with claims that match the evidence.</p>
            <p>Are the rationale for, and objectives of, the Systematic Review clearly stated?</p>
            <p>Partly</p>
            <p>Is the statistical analysis and its interpretation appropriate?</p>
            <p>Not applicable</p>
            <p>If this is a Living Systematic Review, is the &#x2018;living&#x2019; method appropriate and is the search schedule clearly defined and justified? (&#x2018;Living Systematic Review&#x2019; or a variation of this term should be included in the title.)</p>
            <p>Not applicable</p>
            <p>Are sufficient details of the methods and analysis provided to allow replication by others?</p>
            <p>No</p>
            <p>Are the conclusions drawn adequately supported by the results presented in the review?</p>
            <p>Partly</p>
            <p>Reviewer Expertise:</p>
            <p>Blockchain, Corporate Governance, Sustainability, Accounting, Strategic Management, Artificial Intelligence</p>
            <p>We confirm that we have read this submission and believe that we have an appropriate level of expertise to state that we do not consider it to be of an acceptable scientific standard, for reasons outlined above.</p>
