Unbiased and unpredictable randomness is a cornerstone of Web3 security, underpinning everything from consensus protocols to DeFi logic. Although Distributed Verifiable Random Functions (DVRFs) eliminate central points of failure, current designs often have to compromise performance. Most existing protocols are hindered by one of three limitations: proofs that scale linearly with the number of participants, high computational cost of bilinear pairings, or latency introduced by mandatory interactive steps during generation. In this work, we present Icy-DVRF, a protocol that improves DVRFwCP by employing a preprocessing scheme similar to FROST to reduce the number of interaction rounds among participants and lowering the additional communication cost from <inline-formula> <tex-math notation="LaTeX">$O(n^{2} t)$ </tex-math></inline-formula> to <inline-formula> <tex-math notation="LaTeX">$O(t)$ </tex-math></inline-formula> while maintaining constant-size proofs. The downside of our construction is that, relative to DDH-DVRF and GLOW-DVRF, this approach incurs an additional off-chain communication round due to the threshold structure of our non-interactive zero-knowledge proof. This architecture ensures that verification costs remain low, regardless of the set of participants. While theoretical estimates suggest verification costs of approximately one quarter of those of standard designs, our empirical benchmarks on the Sepolia testnet, utilizing the EIP-2537: Precompile for BLS12-381 curve operations, confirm that Icy-DVRF requires only 88,803 gas for full execution. This represents a significant 43.02% reduction in total gas consumption compared to existing pairing-based constructions, saving 67,035 gas per on-chain verification. Off-chain, eliminating DVRFwCP&#x2019;s Augmented Secure-DKG round yields a per-node speedup ranging from a factor of 1.46 at <inline-formula> <tex-math notation="LaTeX">$(n,t)=(5,3)$ </tex-math></inline-formula> to a factor of 4.43 at <inline-formula> <tex-math notation="LaTeX">$(n,t)=(50,34)$ </tex-math></inline-formula>.

LAYER 0: RESTORING REAL-WORLD ONTOLOGY TO DIGITAL ARCHITECTURE The Restoration of Digital Legal Personality through Object-to-Subject Transformation This paper proposes restoring the ontological logic of the physical world within the digital realm. In physical reality, Layer 0 (corporeal presence) implicitly guarantees that an agent is a Subject. The digital world lost this layer, leading to a critical systemic error: the granting of legal capacity to "dead" Objects (code), which results in the mass voidness of transactions due to Vitiated Consent (Defect of Will). The author introduces the concept of Object-to-Subject Transformation. We assert that the only way to eliminate this legal voidness is to re-introduce the human will as a tangible force. The Core Mechanism: The solution is the Organization of the Stream. By actively directing a continuous flow of entropy tokens from physical reality to a digital entity, the human performs a volitional act. This active organization is the endowment of Will, which ontologically transforms the digital entity from an inert Object into a capable Subject. Key Contributions: Restoration of Reality: Layer 0 re-establishes the physical-to-digital link that was lost in standard TCP/IP architecture. Elimination of Voidness: By ensuring "No Will = No Action," the protocol prevents transactions that would be legally void ab initio. Discrete Subjectivity: Legal personality becomes a dynamic state that exists strictly during the moment of active human engagement (Stream Organization). Conclusion This work integrates legal theory and cryptography to create a post-quantum standard of trust, where the human remains the sole source of Subjectivity, preventing the legal and ontological collapse of the digital economy. Keywords: Layer 0, Object-to-Subject Transformation, Digital Legal Personality, Discrete Legal Personality, Sybil Resistance, Capacity to Act, AI Liability, Vitiated Consent, ZK-PoB, Proof of Personhood, Biological Entropy, Model Collapse, Web3 Security, Digital Identity, Intentional Entropy

The rapid evolution of the Internet of Vehicles (IoV) necessitates secure, scalable, and low-latency route navigation mechanisms that can operate in highly dynamic vehicular environments. Emerging paradigms such as Vehicular Digital Twins (VDTs) further enhance IoV ecosystems by enabling real-time virtual representations of physical vehicles, facilitating predictive analytics, intelligent decision-making, and context-aware routing. However, conventional VANET-based approaches suffer from centralized trust dependencies, high computational overhead, and limited adaptability to real-time traffic conditions. This paper proposes BFRN-IoV, a blockchain- and fog-enabled route navigation framework that integrates lightweight ECC-HMAC-based mutual authentication, RSU-assisted fog routing, and global route validation via a Geo-Location Provider (GLP), while leveraging VDTs for enhanced situational awareness and dynamic route optimization. The framework ensures key security properties-including confidentiality, integrity, pseudonymity, unlinkability, and non-repudiation-using ECDH-derived session keys, HKDF-based key expansion, and HMAC verification, while preserving privacy through pseudonym-based identity management. A permissioned blockchain provides immutable and auditable logging of routing interactions without exposing vehicle identities. Simulation results using SUMO and implementation via Web3 demonstrate significant improvements in routing accuracy, along with reduced communication and computational overhead compared to existing approaches. Formal verification using the Scyther tool confirms robustness against replay, impersonation, and man-in-the-middle attacks. The proposed framework delivers a unified, secure, and efficient solution for real-time IoV route navigation, further strengthened by the integration of VDTs in next-generation intelligent transportation systems.

In the modern digital landscape, traditional cen- tralized storage models are increasingly vulnerable to security breaches, suffer from single points of failure, incur high main- tenance costs, and present scalability limitations. The Decen- tralized Storage System (DSS) is proposed as an alternative solution, utilizing distributed ledger technologies, peer-to-peer (P2P) networks, and advanced cryptographic mechanisms to establish a fault-tolerant, secure, and highly available data storage infrastructure. This paper presents the design and imple- mentation of a decentralized storage framework that integrates key blockchain concepts—such as immutability, transparency, and consensus validation—to enhance data integrity and security. The system enables users to store, retrieve, and share data in a fully decentralized manner while ensuring confidentiality through encryption. The work includes a comprehensive architectural and functional analysis of a full-stack, decentralized file storage platform built specifically on the Filecoin Protocol, leveraging the InterPlanetary File System (IPFS) for distributed content addressing and efficient data retrieval. The platform employs a hybrid architecture combining Web2 technologies—Next.js for the frontend, Node.js/Express for the backend, and MongoDB for centralized metadata management—with core Web3 protocols. The analysis confirms the project's success in creating a practical, non-custodial storage solution that abstracts the complexities of the decentralized web. However, a key architectural trade-off is identified: the system's reliance on provider-centric tooling (Boost CLI) and third-party Remote Procedure Call (RPC) endpoints (Glif API) simplifies development but introduces dependencies that compromise the ideal of full, end-to-end decentralization.

Pharmaceutical providers are now facing problems such as counterfeit drugs, lack of openness, different data systems, and weaker regulation. As a result of these shortcomings, medicinal products may be unsafe for patients and this can damage the public's trust in these products. Traditional centralized structures do not have the necessary traceability, security, and resilience for effective management of supply chains. In the context of Industry 4.0, there is an increasing shift toward digital transformation and decentralized industrial systems to improve transparency and automation. This paper describes PharmaChain, a DApp created using blockchain, which is intended to add transparency and trust to the way drugs are managed in the supply chain. With the help of Ethereum and Solidity-based smart contracts, PharmaChain develops a permanent record of every step in the supply chain, starting with buying raw goods and finishing with delivering them to end-users. The platform uses role-based access control, such as manufacturers, distributors, retailers, and regulatory bodies. With a modern MERN stack, PharmaChain ensures the UI is flexible and works well on any device, and Web3.js and MetaMask handle the connection to blockchain on the frontend. The proposed system aligns with Industry 4.0 principles by enabling secure, automated, and decentralized traceability across the pharmaceutical supply chain. Smart contracts significantly reduce the involvement of intermediaries and manual work in the process.

Traditional electoral systems exhibit critical vulnerabilities including vote manipulation, centralized points of failure, and compromised transparency that undermine democratic integrity. This research presents BLOCKELECT, a decentralised blockchain-based secure voting system designed to address these fundamental challenges. The system employs Ethereum smart contracts written in Solidity to enforce immutable voting rules, Web3.js for blockchain integration, and MetaMask wallet authentication for secure voter verification. The proposed architecture implements dual interfaces for voters and electoral commissions, with distributed consensus mechanisms ensuring real-time transaction validation. Smart contracts automatically enforce electoral rules while maintaining cryptographic immutability of all voting transactions. The decentralised design eliminates single points of failure by distributing vote storage and validation across multiple network nodes. System validation employed comprehensive testing including unit, integration, system, and security testing methodologies. Results demonstrate successful prevention of vote tampering, elimination of double voting, and provision of transparent, auditable election results. Implementation utilised Truffle framework, Ganache blockchain simulation, and Node.js back-end services following an Agile Prototype-based Iterative Development methodology. This research demonstrates the feasibility of blockchain technology in creating trustworthy electoral systems, indicating that blockchain-based voting represents a viable solution for enhancing democratic processes while addressing persistent challenges of electoral fraud and lack of public confidence in traditional voting mechanisms.Traditional electoral systems exhibit critical vulnerabilities including vote manipulation, centralized points of failure, and compromised transparency that undermine democratic integrity.

Everything has shifted into a new gear with technology advancement and so has literature. Literature publication is no longer limited to printed pages or e-content. This paper explores the new domain of digitalised literature, crypto-literature. The tools employed for this are blockchain technology and NFTs (Non- Fungible Tokens). Together, these are transforming literary ownership and distribution while empowering authors. This paper delves into how with the help of an alternative to traditional publication, tokenisation of literary works and smart contracts, authors gain transparent royalties, decentralised publishing and copyright gains, which in turn provides creators a greater control over their creations. This paper also explores how, while crypto-literature through Web3 platforms provides creative autonomy and economic empowerment, it also poses several concerns regarding digital equity, accessibility and ecological implications. With the global trends and Indian market in focus, this paper evaluates the advantages and limitations put forward to creators as well as consumers while engaging with this advancing literary system. In short, this paper puts crypto-literature as a focal point of literary innovation, while looking for ethical, inclusive and sustainable practices of this new paradigm.
