The proposed system employs zero-knowledge proofs and homomorphic encryption to facilitate secure computation while utilizing a blockchain to record the computation process and its outcome, thereby ensuring complete traceability. This represents a new approach to secure computation by directly integrating blockchain's capabilities, addressing limitations of traditional approaches and offering enhanced security and auditability. The system's architecture, core mechanisms, and potential applications are thoroughly detailed, highlighting its advantages and future directions.
This paper proposes a novel approach to constructing distributed knowledge graphs (KGs) leveraging blockchain technology. Traditional knowledge graph construction relies heavily on centralized databases, leading to vulnerabilities concerning data security, trust, and potential manipulation. This research addresses these shortcomings by introducing a decentralized, trustworthy, and traceable KG built upon a blockchain network. The core mechanism involves storing KG nodes and edges directly on the blockchain, coupled with smart contracts to facilitate knowledge validation, verification, and updates. This ensures data integrity and reliability while providing an immutable audit trail. The proposed system offers enhanced security, transparency, and accountability, fundamentally changing how KGs are built and maintained. The research explores the technical challenges and potential benefits of this decentralized approach, demonstrating its feasibility and suitability for a variety of applications.

Conventional service evaluation systems are increasingly plagued by data opacity, susceptibility to tampering, and delayed feedback loops, which erode stakeholder trust and hinder effective quality governance. To address these critical challenges, this study proposes and empirically validates a blockchain-enabled framework for trusted closed-loop management of the entire service evaluation process. The proposed architecture synergizes distributed ledger technology, autonomous smart contracts, and a dynamic Bayesian trust scoring model to achieve real-time data verification, automated corrective feedback, and adaptive trust computation. We analyzed a comprehensive dataset of 1,200 service interactions across the hospitality, healthcare, and e-commerce sectors, characterized by customer satisfaction scores ranging from 5.1 to 9.8, reliability indices between 0.72 and 0.96, and normalized positive interaction frequencies from 0.42 to 0.89. Empirical results demonstrate that the integration of the blockchain framework significantly elevated mean trust scores from 0.71 (± 0.12) to 0.88 (± 0.09), representing a statistically significant 23.7% improvement. Furthermore, the system reduced the variance in satisfaction ratings by 0.48 and lowered overall service discrepancy rates by up to 15.4%. Sector-specific dynamic weight adjustments yielded optimized outcomes, including a 7.4% increase in reliability for healthcare and a 6.3% improvement in consistency for hospitality. Comparative analysis reveals that while conventional digital evaluation systems typically achieve only 5–12% performance gains, our blockchain-based approach substantially enhances trust, accuracy, and process transparency. Crucially, the closed-loop mechanism facilitated timely interventions, reducing critical service deviations by 17.5% in healthcare and 15.4% in e-commerce. These findings offer robust theoretical validation and practical guidelines for deploying transparent, accountable, and adaptive service evaluation ecosystems in diverse industrial contexts.
This paper proposes a novel approach to governing distributed machine learning (ML) models using blockchain technology. The core claim is to establish a decentralized platform for managing ML model versions, controlling access permissions, and distributing rewards, all while enhancing transparency and trust. The proposed mechanism leverages blockchain's immutability and smart contract capabilities to record model metadata, training data provenance, and participant information. This allows for automated execution of governance rules, mitigating issues associated with traditional, centralized ML model management, such as single points of failure, biased data handling, and lack of transparency. The system aims to foster a more equitable and trustworthy environment for collaborative ML development and deployment. Key performance metrics, such as model accuracy, data integrity, and participant engagement, are inherently tracked and verifiable through the blockchain.
This paper proposes a novel approach to software supply chain security management leveraging the inherent characteristics of blockchain technology. The core claim is to build a robust management system capable of guaranteeing the integrity and traceability of software components throughout their lifecycle. The proposed mechanism utilizes a blockchain network to record critical data points related to the software supply chain, including code commits, build processes, and security audits. Smart contracts are then employed to automate security checks, enforce access control, and trigger alerts based on predefined rules. This approach addresses the escalating risks associated with compromised software supply chains by providing an immutable and auditable record of all activities. The research highlights the potential of blockchain to significantly enhance software security and trust within complex, distributed development environments. The key contribution lies in the systematic application of blockchain and smart contracts specifically tailored for supply chain security, offering a verifiable and resilient solution.
Anomaly detection in dynamic graphs underpins fraud analysis, cybersecurity and platform integrity, yet deep detectors remain opaque: a flagged interaction arrives with a score and no account of which counterparty or which moment produced it. The prevailing post-hoc remedy fits an auxiliary model to a frozen detector, so faithfulness is estimated rather than guaranteed, and to our knowledge no dynamic-graph detector emits an explanation as a native product of its own forward pass. We propose EVIDENT (EVIDence-bottlenecked intrinsic dEtection for evolving Networks over Time), an ante-hoc detector whose anomaly score is computed exclusively from a sparse, dually-factorised evidence set selected within that pass, so the explanation costs no additional inference. Gated tokens leave the attention softmax entirely rather than being attenuated, so sufficiency holds by construction rather than by measurement. On Bitcoin-OTC with real distrust labels, EVIDENT attains 0.7947±0.0069 AUC under supervision matched to unsupervised baselines—exceeding the transformer detector TADDY by 26.0 points—from 10% of its evidence pool, retaining over 97% of an unconstrained model of identical architecture. Under a density-matched mask protocol its rationale exceeds an equalsize random subset by +0.2145 AUC (6.6σ) and selects priornegative-rating tokens at 1.29–2.49× the random rate; ablating the complement objective leaves detection unchanged while collapsing that advantage 4.5-fold. On a unified injected benchmark against eleven learned detectors and a parameter-free degree heuristic, EVIDENT ranks first at 0.9766 AUC while denied the cardinality channel they retain—though there its rationale ceases to separate, isolating token heterogeneity rather than the selection mechanism as the binding constraint on intrinsic explainability. We further document two evaluation defects—neighbourhood cardinality leakage under edge injection, and incomplete token removal in gated attention—with diagnostics that detect them.

There are several types of multimodal data such as text, image, audio, video, and sensor streams. It is evolving at a very high rate, which has resulted in not only complicated security issues but also enormous potential opportunities in advanced analytics and intelligent applications. The significant security issues in multimodal data management are analyzed in this chapter, such as data integrity, data confidentiality, authentication, access control, and privacy protection. Multimodal data is vulnerable to attacks such as adversarial attacks, data breaches, unauthorized access, and cross-modal inference, and due to its dispersed and heterogeneous nature, such attacks can compromise sensitive information. The chapter examines diverse security controls to address these challenges, such as safe multimodal fusion, blockchain architecture, cryptography, federated learning, differential privacy, and robust authentication processes. It is concentrated on scalable and real-time protection methods that are effective in edge-cloud designs and big data environments. This combination of approaches will enable businesses to ensure dependable multimodal data analytics that will safeguard user privacy and system reliability and allow making safe and efficient decisions in any field of application.
Abstract The integration of Internet of Things (IoT) and blockchain technologies enables secure, decentralized data management for real-time applications. However, limitations in processor, memory, and energy resources restrict the direct processing of large datasets. Notably, Garbage Collector (GC) mechanisms in high-level languages increase variance in P99 queue latencies, while expanding data volumes can result in system crashes due to Out-of-Memory (OOM) errors. This study introduces a hybrid Rust-Python Simplified Payment Verification (SPV) native hashing engine deployed on resource-constrained edge devices (Raspberry Pi Zero W) and high-capacity gateways (Raspberry Pi 5). Laboratory evaluations demonstrate that the hybrid system achieves a verification capacity of 34,000 Merkle nodes per second, representing a 4.35-fold speed improvement over pure Python on the Pi Zero W. Additionally, the system reduces GC-induced latency fluctuations and offers up to 75% potential energy savings, as indicated by theoretical modeling based on active processor cycle analyses. Bottleneck analyses on Raspberry Pi 5 indicate that Foreign Function Interface (FFI)-related data transfer costs limit parallel processing benefits for low-volume datasets. In contrast, the scalability of the hybrid architecture is evident with datasets containing 1.5 million records. The memory-mapped streaming architecture minimizes OOM risks and achieves a cache miss rate of 0.34%. Memory safety was assessed using the MIRI tool.
Live-streaming (LS) e-commerce has become a key sales channel linking manufacturers with end markets, yet live-streaming supply chains (LSS) still suffer from information asymmetry and a lack of credibility in the disclosures. Although AI and blockchain offer potential for real-time, traceable, and interactive information sharing, their impact on disclosure strategies remains underexplored in the field of production operations. This study develops game models for a manufacturer and a live-streaming enterprise (LSE), incorporating rational, risk-averse behaviours under both traditional and AI-blockchain disclosure mechanisms. Through model analysis, optimal strategies from the production stage to the sales stage have been identified. Results reveal three disclosure phases – full disclosure, partial disclosure by LSE only, and partial disclosure by both – while LSE consistently exhibits stronger disclosure willingness. The trust-amplifying effect generated by AI-blockchain technology is non-linear. Adoption of AI-blockchain enhances disclosure and profits when costs are below critical thresholds, whereas traditional strategies offer greater operational robustness under high uncertainty or low willingness. Findings highlight how digital technologies reshape incentives and pricing within SCs, providing practical guidance on information disclosure strategies, technology investment decisions and the improvement of SC operational performance.
Blockchain is one important building blocks of the Internet of the future, called Web3. The Blockchain technology supports a wide range of applications, spanning from Smart Cities and automotive industries, from agriculture to energy. The healthcare sector, in particular, has experienced a profound impact from blockchain-based technologies, paving the way for the development of true digital healthcare systems. By enabling secure and immutable data storage, and facilitating the sharing of this information among all nodes possessing a local copy of the distributed ledger, blockchain plays a vital role in the analysis of healthcare data. This paper provides a comprehensive survey of the main blockchain platforms utilized in the digital healthcare, integrated with a comparative analysis. In addition, the implementation of Innovative permissioned Blockchain for eHealth (IBEH) is presented and discussed in detail. IBEH addresses key challenges in digital health data management, including secure and controlled access to sensitive health information, ensuring data integrity and traceability, and secure sharing between different healthcare institutions and organizations. This is made possible by decoupling the application and blockchain layers and by a flexible, customizable, and easily deployable infrastructure. IBEH integrates the application-oriented and embedded layer with that of a blockchain network built with the MultiChain platform, which uses smart contracts with permissions, REST APIs, and RPC calls. The main features and its associated smart contracts within the healthcare domain are discussed. Finally, the analysis of performance is provided.
