A Distributed Ledger Technology Solution for Connecting E-mobility Partners

Convergence of Distributed Ledger Technologies with Digital Twins, IoT, and AI for fresh food logistics: Challenges and opportunities

Blockchain technology is propelled by distributed ledger technology (DLT). Due to its natural and unfalsified attributes (reliable, efficient, resilient and transparent) pushing it to a prime choice in several monetary related applications and financial services. With the amalgamation of artificial intelligence, various blockchain systems-based limitations can be resolved easily and rapidly in order to provide high-performing and useful results. This paper means to present a through survey on the topical developments and solutions in blockchain technology based on artificial intelligence for resolving its problems. The findings of this study will conclude the important knowledge and direction on the idea of proposing blockchain-based systems to support time-sensitive and real-time-specific applications.

The Internet of Things (IoT) paradigm aims to enhance human society and living standards with the vast deployment of smart and autonomous devices, which requires seamless collaboration. The number of connected devices increases daily, introducing identity management requirements for edge IoT devices. Due to IoT devices' heterogeneity and resource-constrained configuration, traditional identity management systems are not feasible. As a result, identity management for IoT devices is still an open issue. Distributed Ledger Technology (DLT) and blockchain-based security solutions are becoming popular in different application domains. This paper presents a novel DLT-based distributed identity management architecture for edge IoT devices. The model can be adapted with any IoT solution for secure and trustworthy communication between devices. We have comprehensively reviewed popular consensus mechanisms used in DLT implementations and their connection to IoT research, specifically identity management for Edge IoT devices. Our proposed location-based identity management model is generic, distributed, and decentralized. The proposed model is verified using the Scyther formal verification tool for security performance measurement. SPIN model checker is employed for different state verification of our proposed model. The open-source simulation tool FobSim is used for fog and edge/user layer DTL deployment performance analysis. The results and discussion section represents how our proposed decentralized identity management solution should enhance user data privacy and secure and trustworthy communication in IoT.

Internet-based platform businesses outcompete traditional brick and mortar business on nearly all measures of comparison. Similarly, distributed ledger technology (DLT) businesses depend on the Internet and show a lot of promise in multiple business verticals. Yet, Internet-based platform businesses and DLT businesses have not reached their full potential. Multiple studies, data, and anecdotal evidence suggest that one core factor that undermines their evolution is the worldwide decreasing trust in the Internet and under-developed trust in decentralized technology solutions. Semada and the Semada Research Institute (SRI) believe that a decentralized reputation network can reverse that trend to increase trust in the Internet and increase decentralized technology adoption. We call this solution the Semada Internet of Trust—a network that uniquely captures real world information, context, and value in cryptographic transactions generating transparently validated consensus on truth. Through the creation of unconscious and conscious trust in decentralized networks adoption becomes a desirable outcome and increases. Semada is a unique blockchain platform well suited for the decentralized web. Semada’s core architecture continually resolves the blockchain trilemma by combining: (i) decentralization; (ii) scale, and; (iii) security. Semada’s version of proof-of-stake—a.k.a. the Anchor Protocol—is a unique consensus algorithm that enables block propagation through reputation staking and verification. Through its Sockpuppet Protocol, Semada is resilient to deceptive fake Internet identities, so-called sockpuppet accounts, and 51% attacks. Through its Persona Protocol, Semada facilitates digital sovereignty, self-sovereign identity, privacy, security and decentralized reputation. Trust enabling reputation can only be earned over time on the Semada network. The Semada Internet of Trust creates a framework of trust through reputation and incentive optimization that enables market conditions for unprecedented business models and market capitalization while reducing adverse selection and moral hazards for transacting parties. The network will provide information symmetry while reducing transaction costs for market participants. Businesses will leverage the platform to achieve efficiencies across verticals.

The food supply chain is extremely complex owing to the presence of multiple entities and the perishable nature of goods. In India, the infrastructure facilitating collaboration among stakeholders is very weak which leads to participants working in silos. The food supply chain needs sophisticated ways to gather, integrate and track data published by various stakeholders so as to function effectively and efficiently. Blockchain as a distributed digital ledger technology ensures transparency, traceability, and security, and has shown promise for easing food supply chain management problems. In this paper, we propose Agrichain: a Blockchain-based, low-cost Distributed Ledger Technology solution for the Indian food supply chain ecosystem with detailed design and specifications. The proposed system will enable various stakeholders to register for their specific roles in the supply chain and publish relevant information to the blockchain. This information will then be used to track and trace perishable goods as they move forward in the chain.
