New-generation traffic violation systems are often plagued by issues related to data tampering, transparency, and poor record-keeping. To overcome these limitations, this paper proposes EtherFineChain, a blockchain-based framework for traffic violation logging and cryptocurrency penalty enforcement utilizing smart contracts. The system records decentralized, tamper-proof and verifiable storage of key violations data like vehicle number, evidence references for legitimate stakeholders. A working prototype has built and deployed on the simulated environment - Ganache, enabling automated fine deduction and immutable record keeping. Experimental evaluation shows that the average transaction latency is 134.48 ms and transaction throughput is 7.43 transactions/sec(approx.), and handles over 500 records per hour under simulation. Although the current version is founded on pre-processed inputs, the architecture is designed to support real-time detection and automated pipelines in upcoming versions. EtherFineChain provides a scalable and independent foundation for digital traffic management, laying the groundwork for secure integration into smart-city infrastructures.
Secure interoperability across heterogeneous blockchains remains one of the most pressing challenges in Web3 with existing bridge protocols vulnerable to both classical exploits and emerging quantum threats. This paper introduces QLink a quantum-safe Layer 3 interoperability protocol that integrates postquantum cryptography (PQC) quantum key distribution (QKD) and hardware security modules (HSMs) into a unified validator architecture. To our knowledge, QLink is the first interoperability framework to combine these mechanisms to secure validator communication proof aggregation and key management. Validators exchange encryption keys through QKD channels, achieving information-theoretic security against interception, while cross-chain proofs are generated and aggregated with NIST-standardized PQC algorithms. Private keys remain sealed inside HSM enclaves mitigating the risk of theft or leakage. Deployed as a dedicated Layer 3 protocol QLink operates independently of Layer 1 and Layer 2 chains providing a scalable decentralized foundation for secure cross-chain messaging and asset transfer. Experimental evaluation using network simulations demonstrates that validator communication overhead remains sub-second while security guarantees extend beyond current bridge architectures to resist both classical and quantum adversaries. By addressing today vulnerabilities and anticipating future quantum threats QLink establishes a practical and future-proof pathway for blockchain interoperability.

This study introduces a blockchain-based framework designed to strengthen the privacy, security, and verifiability of Electronic Health Records (EHRs) within Internet of Things (IoT)-driven healthcare environments. The proposed hybrid model combines blockchain for tamper-proof data logging, the InterPlanetary File System (IPFS) for scalable and efficient off-chain storage, and advanced cryptographic mechanisms such as smart contracts and Zero-Knowledge Proofs (ZKPs) to enable secure access management. Within this architecture, patients retain ownership and control of their encrypted medical data, while healthcare providers obtain permissioned access verified through ZKP-enabled smart contracts. Comparative evaluation reveals notable performance gainsâ92% enhancement in data integrity, 87% improvement in privacy protection, and a 30â35% reduction in unauthorized accessârelative to conventional centralized EHR systems. Additionally, the framework demonstrates over 40% higher auditability and trust among healthcare entities. Remaining research challenges include achieving cross-platform interoperability, ensuring regulatory compliance, and integrating advanced privacy-preserving technologies such as federated learning and homomorphic encryption. Future work aims to optimize consensus mechanisms and align the framework with HL7 FHIR standards to facilitate scalability and real-world deployment.
The traditional credit scoring industry, dominated by a few centralized bureaus, suffers from opacity, data insecurity, and a lack of user-controlled data sovereignty. This paper introduces Zk-Cred, a novel decentralized protocol designed to address these challenges by leveraging a unique combination of Fully Homomorphic Encryption (FHE), Zero-Knowledge Proofs (ZKPs), and W3C Verifiable Credentials (VCs). Zk-Cred empowers individuals to generate a verifiable, privacy-preserving credit score without revealing their underlying financial data to any third party. The protocolâs core mechanism involves users encrypting their financial data client-side using an FHE scheme. A decentralized network of nodes then executes a publicly auditable credit scoring model on this encrypted data, computing a score that is only ever decrypted by the user. The user can then generate a ZKP to prove the correctness of the computation and receive a tamper-proof VC representing their creditworthiness. This VC can be presented to financial service providers, such as DeFi lending platforms or traditional institutions, for instant verification. By synthesizing these cryptographic primitives, Zk-Cred offers a new paradigm for credit scoring that is transparent, secure, and user-centric, with significant potential to enhance fairness and access in the global fintech ecosystem.

With increasing dependence on AI for medical imaging diagnostics, privacy concerns and strict regulations continue to restrict data sharing across healthcare institutions. To address this, we propose a novel framework that enables cross-institutional collaboration without compromising sensitive patient information. Our system integrates federated learning with advanced privacy-preserving techniques, including homomorphic encryption, secure aggregation, differential privacy, and zero-knowledge proofs. Hospitals retain their data locally and contribute encrypted, noise-added model updates, ensuring that raw data never leaves the premises. Secure aggregation and encryption prevent any entity, including the central server, from accessing individual contributions. Differential privacy introduces mathematically bounded noise to mitigate risks from inversion and membership attacks. Meanwhile, zero-knowledge proofs allow clients to verify the legitimacy of their training process and updates without revealing internal computations or data. This layered privacy defense effectively counters gradient inversion, model poisoning, and membership inference attacks, all while maintaining strong diagnostic performance. Evaluated on real-world medical imaging datasets, our method balances accuracy with compliance to privacy laws like HIPAA and GDPR. The proposed architecture offers a scalable and trustworthy approach to enable AI-driven diagnostics across hospitals, ensuring patient confidentiality is never compromised.

As traditional and electronic voting methods are being increasingly scrutinized for security, transparency and availability, blockchain has emerged as a way to address some of these concerns. This paper describes a blockchain-based decentralized voting system which employs Ethereum smart contracts for controlling the voting procedure based on the features and characteristics of the public blockchain, such as security, immutability and transparency, hence guaranteeing a secure and fair electoral system. The voting process is automated and secured, thus a provable way to the votes casting or votes counting. Security scalability and user authentication are used to verify the system. The knowledge base system provides secure electronic voting, transparency of elections, builds trust among voters due to a real-time computational claimability of election results. This paper suggests a framework for building a blockchain-based voting system on a larger scale and more reliable than the existing voting system.
Blockchain technology is transforming real estate with its transparency and security. Its decentralized, immutable ledger ensures all transaction records are tamper-proof and visible. This paper addresses a critical flaw in the traditional market: fragmented systems that often overlook approvals from inspectors and lenders. By leveraging the Ethereum blockchain and its smart contracts, Block realty automates agreements, eliminating intermediaries and enhancing efficiency. The paper utilizes the ERC-721 standard to tokenize real estate assets, converting properties into unique digital tokens. This fundamentally changes asset management, enhancing market liquidity and global accessibility. A key feature is a comprehensive three-step approval process, ensuring all stakeholders-buyers, lenders, inspectors, and sellers are actively engaged. Each party's approval is immutably recorded on the blockchain, creating a verifiable chain of custody that boosts transaction integrity. The use of Non-Fungible Tokens (NFTs) also facilitates fractional ownership, allowing multiple investors to jointly own a single property. This democratizes real estate investment by lowering the barrier to entry. For data management and cost optimization, Blockrealty integrates the Inter Planetary File System (IPFS), a decentralized storage protocol for securely housing property images and metadata. Additionally, seamless Metamask integration provides a user-friendly interface. Looking ahead, upcoming Ethereum advancements like the Pectra upgrade are poised to enhance Ethereum's scalability and efficiency, further strengthening the foundation for platforms like Blockrealty by enabling them to handle transactions more effectively and reliably.

Zero-Knowledge Proof (ZKP) has been widely applied in fields such as blockchain and privacy-preserving computing. However, the proof generation process remains computationally complex and time-consuming, which limits its further applications. Various schemes have been proposed to optimize the underlying modular operations with dedicated hardware support, but existing schemes still face low-efficiency problems. To address the problems, we propose an efficient Barrett modular multiplier design, especially for ZKP. Evaluation on a Xilinx XCVU9P FPGA shows that, compared to two existing pipelined designs, the proposed design improves throughput per slice by up to 20.4% and 49.6%, respectively, and achieves an $8.6 \times$ improvement over an existing non-pipelined design.
Federated Learning (FL) has emerged as a distributed paradigm enabling multiple participants to collaboratively train machine learning models without sharing their raw data. By keeping data local, FL mitigates many privacy risks inherent to centralized learning architectures. However, despite this promise, recent research has revealed that exchanged gradients can still leak sensitive information about local datasets. Furthermore, most existing approaches rely on strong and often unrealistic trust assumptions toward the central server, while providing no means to verify whether privacy-preserving mechanisms have been correctly enforced. These limitations expose a critical gap between theoretical privacy guarantees and their practical implementation in real-world federated systems.This thesis investigates how to bridge this gap by combining differential privacy (DP) with cryptographic and verifiability protocols to achieve verifiable and trust-reduced federated learning. First, we explore the use of additive homomorphic encryption to protect client updates and minimize reliance on a trusted aggregator. Second, we introduce a non-interactive verifiability protocol based on zk-SNARKs and cryptographic hashes, allowing third parties to prove and verify the correct application of DP without revealing sensitive information. Finally, we propose ProoFed, a distributed framework that leverages secret sharing to decentralize noise generation and integrate verifiable aggregation proofs in zero knowledge, thereby eliminating single points of trust.
Abstract This paper revisits Virgo, a well-known transparent zero-knowledge proof system that has been used in many subsequent studies. Through our analysis, we uncover previously overlooked limitations and several exploitable security vulnerabilities within Virgoâs zkVPD protocol design and implementation. We subsequently address these issues and improve Virgoâs zkVPD protocol. Our improvements feature simplified but more efficient VPD and zkVPD algorithms, offering enhanced support for computations over binary fields and their extension fields.
Financial institutions are currently faced with suffering never experienced before as they strive to guarantee the privacy of data and address the demands of regulation to report and cooperate in machine learning. This paper proposes PrivChain-AI, a novel blockchain-based federated learning system designed to facilitate secure and privacy-preserving financial reporting and access control. The proposed framework will integrate three key components: differential privacy, homomorphic encryption, and smart contract-based governance, enabling cooperative model training across financial institutions while preventing the leakage of sensitive information. PrivChain-AI is a hierarchical design that incorporates permissioned consensus protocols and utilises zero-knowledge proof verification to authenticate transactions. It has been demonstrated that the performance is higher than that of the actual financial data, with an outcome of 94.7% accuracy in fraud recognition at the cost of e-differentiation privacy, where Ï” = 1.0. It is 40% faster in terms of communication overhead and ensures regulatory compliance, as it features immutable audit trails. The analysis of performances reveals that a privacy preservation metric improves by 78%, and access control granularity is improved by 62% compared to the current state-of-the-art approaches. The PrivChain-AI paradigm introduced provides a new analytical model for safe, collaborative finance, meeting the highest standards and ensuring compliance with relevant regulatory jurisdictions.
Digital product passports outline information about a productâs lifecycle, circularity, and sustainability-related data. Sustainability data contains claims about carbon footprint, recycled material composition, ethical sourcing of production materials, etc. Also, upcoming regulatory directives require companies to disclose this type of information. However, current sustainability reporting practices face challenges, such as greenwashing, where companies make incorrect claims that are difficult to verify. There is also a challenge of disclosing sensitive production information when other stakeholders, such as consumers or other economic operators, wish to verify sustainability claims independently. Zero-knowledge proofs (ZKPs) provide a cryptographic system for verifying statements without revealing sensitive information. The goal of this research paper is to explore ZKP cryptography, trust models, and implementation concepts for extending DPP capability in privacy-aware reporting and verification of sustainability claims in products. To achieve this goal, first, formal representations of sustainability claims are provided. Then, a data matrix and trust model for generating proofs are developed. An interaction sequence is provided to show different components for various proof generation and verification scenarios for sustainability claims. Lastly, the paper provides a circuit template for the proof generation of an example claim and a credential structure for their input data validation. The proposed approach is assessed using a scenario-based evaluation to check the performance metrics for data credential verification and proof generation for verifying material composition in a product.

The research presents SmartProof as an artificial intelligence system which uses large language models and blockchain technology to create automated decentralized agreement generation and auditing and validation processes. SmartProof combines natural language code generation with AI security evaluation and IPFS-based decentralized storage and EIP-712 compliant digital signature functionality. The system enables users to develop smart contracts from high-level descriptions which then undergo automated verification before the system finishes the agreement process through blockchainbased verification of on-chain registration. The prototype system shows that AI-based contract creation tools shorten development periods and minimize programming mistakes and the multiagent auditing system identifies system weaknesses to generate trust-based risk assessment for deployment. The system achieves improved performance because it stores data outside the blockchain network and manages digital signatures which reduces gas costs and boosts system performance. SmartProof enables organizations to handle multiple agreements through one system which provides complete agreement transparency and complete security from contract inception to blockchain deployment.
In recent years, blockchain technology has gained considerable attention, with increasing interest in diverse fields, including banking, Retail, consumer products, Insurance, Real Estate, Government, healthcare, Supply Chain, and the automotive industry. Blockchain offers a secure, distributed database that can run without a central authority or administrator. Blockchain uses a distributed, peer-to-peer network called Digital Blocks to create a continuous, growing list of ordered records. Each transaction, represented in a cryptographically signed block, is then automatically authenticated by the network. Over time, however, it has become clear that the impact of blockchain as a technology is likely to be much broader than just the cryptocurrency domain and far deeper than simple distributed ledger storage. This detailed survey aims to summarize the most significant developments in blockchain implementation. This article will examine different domains where blockchain has been impacted and where implementation is expected in the future.

Cross-chain technology, as a key driver for enhancing interoperability of blockchains, enables asset transfer and exchange between different blockchains. At present, cross-chain models based on light clients are widely adopted due to their fully decentralized nature and applicability to diverse scenarios. However, the rapid advancement of on-chain analysis techniques, such as address linkage and fund flow tracking, has significantly increased risks of de-anonymization in cross-chain transactions, posing serious privacy challenges. In this paper, we propose SharedRXC, a privacy-preserving asset cross-chain scheme for the light-client cross-chain model, which guarantees address unlinkability without extra privacy trust assumptions. First, to hide cross-chain addresses during interchain transmission, we propose the Ring Account (RA) to replace a single address for sending or receiving funds. In addition, we propose a zero-knowledge proof-based method to verify virtual identity ownership, allowing the virtual identity to track fund balances without exposing the addresses. Second, to prevent the exposure of the link between an address and its virtual identity caused by fund amount differences during deposits or withdrawals, which would compromise address unlinkability, we propose the Shared Burn/Mint method to obscure on chain fund change differences. Based on the liability equalization mechanism, we design two privacy-preserving cross-chain protocols: the cross-chain asset transfer (SharedRXC.T) and exchange (SharedRXC.E) protocols. Finally, we evaluateSharedRXC.TandSharedRXC.E, which reduce gas costs by 30% to 40% compared to zkCross and achieve execution times in the millisecond range. Therefore, SharedRXC provides a practical privacy-preserving solution for cross-chain financial applications in the multi-chain ecosystem.

Identity management is a critical component in egovernance, ensuring secure, reliable, and efficient verification of citizens' identities. With increasing digitization, protecting personal data while enabling seamless access to government services has become essential. Existing identity management systems often rely on centralized databases, which are prone to data breaches, unauthorized access, and lack of transparency, raising concerns over privacy and trust. To address these challenges, this research proposes a Blockchain Identity Framework that integrates Zero-Knowledge Proof (BIF-ZKP) authentication with blockchain consensus mechanisms. In this framework, ZKP enables users to prove their identity without revealing sensitive information, while blockchain ensures that identity records are decentralized, tamperproof, and auditable. The consensus mechanism guarantees that all identity transactions are verified by multiple nodes, reducing the risk of fraud and unauthorized modifications. The proposed method is applied in an e-governance context to securely manage citizens' digital identities, enabling authentication for services such as online voting, tax filings, and social welfare schemes while maintaining privacy. Experimental evaluation demonstrates that the BIF significantly enhances data security, privacy preservation, and trustworthiness compared to traditional centralized identity systems. It reduces the risk of identity fraud and ensures the verifiable and transparent management of citizens' information. The proposed method improves data security by 96.2 % and reduces fraud by 89 %.
ABSTRACT Phishing attacks in decentralized Web3 systems continue to evolve beyond the detection capabilities of traditional Web2 security models. Existing decentralized authentication systems typically lack either mutual verification or dynamic threat awareness. We present PhishGuard++, a crossâchain, privacyâpreserving authentication framework that introduces two core innovations: (1) a novel mutual ZeroâKnowledge Proof (ZKP) protocol that validates both users and services using Decentralized Identifiers (DIDs), and (2) a realâtime, onâchain Graph Neural Network (GNN) threat oracle that assigns phishing risk scores integrated directly into smart contractâbased access control logic. A stakeâbased validator reputation system with antiâcollusion incentives further reinforces trust without sacrificing decentralization or privacy. Experimental results on a simulated Arbitrum testnet show a statistically significant 40.4% reduction in phishing success rate across five attack vectors, 98.6% authentication accuracy, and subâsecond latency with gasâefficient operations. Unlike prior works that independently apply ZKPs, DIDs, or GNNs, this framework offers the first privacyâpreserving, mutual authentication system that combines these technologies with stakeâbased economic enforcement and realâtime smart contract enforcement. The novelty lies in the architecture's realâtime threatâaware access decisions, validatorâlinked risk accountability, and practical crossâchain deploymentâan integration not previously achieved.
With the rapid development of geological blockchains and Internet of Things-based data acquisition technologies, massive amounts of heterogeneous data are constantly emerging. However, this data is stored in a distributed manner across different organizational or business blockchains. Data sharing among multiple geological blockchains faces numerous challenges, either exposing sensitive data during verification or lacking effective authorization mechanisms. Therefore, how to achieve fine-grained access control and privacy protection across multiple blockchains has become a critical issue that must be addressed in geological data sharing. In this paper, we propose GeoCross, a cross-chain geological data sharing framework that enables fine-grained authorization management and privacy protection. First, GeoCross provides a hierarchical hybrid encryption mechanism that uses symmetric encryption for geological data protection and ciphertext-policy attribute-based encryption to enable flexible cross-chain access policies. Second, we integrate a Groth16-based zero-knowledge proof mechanism, which allows a chain to verify the existence, integrity, and accessibility of off-chain data without revealing the content. Furthermore, we introduce a Reputation-based Non-interactive Relay node Selection protocol (RNRS), which enhances the trustworthiness and fairness of cross-chain routing. Finally, we implement GeoCross in a multi-chain Hyperledger Fabric environment and evaluate its performance under real-world workloads. Results show that Groth16 verification requires only three bilinear pairings, achieving a throughput of up to 390 tps on a single chain and 1550 tps in a concurrent multi-chain environment. Even with 50% malicious nodes, the RNRS protocol still maintains a success rate of over 91%. These results demonstrate that GeoCross provides an efficient and practical solution for secure and privacy-preserving cross-chain geological data sharing.
Abstract Fair exchange is a cryptographic protocol that enables two parties to exchange their electronic data fairly, i.e., it ensures that no one can steal the other partyâs item. FairSwap and OptiSwap are well-known fair exchange protocols for files and coins based on smart contracts. Although the design principles for the two protocols are similar, there is an extreme difference in round complexity and communication overhead between the two protocols. This gap can be a barrier to users since they must choose one of them. In order to remove the barrier, this work generalizes these two protocols. It proposes a fair exchange protocol that allows users to adjust the communication overhead and the number of rounds by a newly introduced parameter. Our protocol contains FairSwap, OptiSwap, and protocols with intermediate efficiency between them. Moreover, to evaluate the gas costs of our protocol, we present a performance evaluation of the proposed protocol by Solidity implementation over Ethereum.
Secure electronic voting (e-voting) systems have become an essential component of modern democratic processes, demanding strong guarantees of privacy, integrity, verifiability, and resistance to coercion. Homomorphic commitment schemes, which integrate the properties of commitment schemes with homomorphic encryption, provide a promising approach to meeting these requirements by enabling computations on encrypted or committed data without revealing the underlying information. This capability allows secure vote tallying while preserving voter anonymity. This paper presents a comprehensive review of homomorphic commitment schemes within secure voting infrastructures, focusing on key security models such as privacy, verifiability, coercion resistance, and robustness against malicious adversaries. It also examines optimization techniques, including batching, threshold cryptography, and blockchain integration, which enhance system efficiency and scalability. Furthermore, emerging paradigms such as post-quantum cryptography and decentralized systems are discussed for their potential impact on voting protocols. The study highlights advancements in cryptographic primitives, zero-knowledge proofs, and distributed ledger technologies, while providing a comparative analysis of multiple research contributions. The findings indicate that although homomorphic commitment schemes significantly enhance transparency and privacy, challenges related to computational complexity, scalability, and real-world implementation persist, suggesting the need for lightweight, quantum-resistant, and hybrid secure voting solutions. , , , ,
Blockchain consensus mechanisms form the backbone of decentralized systems by ensuring agreement among distributed nodes without a central authority. At the core of these mechanisms lie number-theoretic foundations, including cryptographic primitives such as modular arithmetic, hash functions, elliptic curve cryptography, and zero-knowledge proofs. These mathematical constructs enable secure transaction validation, identity verification, and resistance against adversarial attacks. This paper presents a systematic review of number-theoretic foundations underpinning blockchain consensus mechanisms, focusing on methods, architectural implementations, and emerging research directions. The study analyses widely adopted consensus algorithms such as Proof of Work (PoW), Proof of Stake (PoS), and Byzantine Fault Tolerant (BFT) protocols, highlighting their dependence on number theory for ensuring security, randomness, and fairness. A comprehensive review of 30 studies published between 2018 and 2023 is conducted to examine advancements in cryptographic techniques such as verifiable random functions (VRFs), homomorphic encryption, and zero-knowledge proofs. These techniques play a crucial role in improving scalability, privacy, and efficiency of blockchain systems. The findings reveal that while number-theoretic approaches provide strong security guarantees, challenges such as computational overhead, scalability, and energy consumption persist. The paper concludes by identifying future research directions, including post-quantum cryptography, lightweight cryptographic protocols, and AI-assisted consensus optimization.
Smart contracts rely on blockchain oracles to access off-chain data, yet existing oracle designs often face challenges such as untrustworthy data sources, weak temporal guarantees, and limited verifiability. This work presents Ivy Oracle, a robust and time-trustworthy data feed framework that enhances the reliability and auditability of off-chain information for smart contracts. Ivy Oracle integrates trusted execution environments (TEEs) for secure data acquisition, an external time server for authenticated timestamps, and a PageRank-based trust model to evaluate source credibility. We implement and evaluate Ivy Oracle on the Ethereum Sepolia testnet, demonstrating that it achieves up to 63.6% lower on-chain gas consumption than Chainlink for signature verification while maintaining only a slight increase in communication overhead due to its dual-attestation mechanism. These results confirm that Ivy Oracle provides strong time trustworthiness and data reliability with minimal performance cost, making it suitable for latency-sensitive blockchain applications.
