“…Further, network malfunctioning can affect the consensus protocol-messages may arrive too late or not arrive at all. Focusing now on IOTA-it addresses not only the specifics of IoT devices but also compensates for some drawbacks of TBC, which are energy consumption, latency, scalability problems, and transaction costs [7,17]. In order to counter these problems, a new validation mechanism is introduced, where IOTA classifies nodes into full and light ones.…”

“…The light ones with low computing resources rely on full nodes' support for validations when attaching new transactions to the tangle. As load balancing may be a problem, a mechanism for a fair distribution of workload among full nodes is needed [7]. Consequently, IOTA has a solid, scalable transaction confirmation capability, which improves BC's inefficiency and unsustainability by eliminating the mining pools [18].…”

“…On the other hand, the Internet of Things (IoT) devices are becoming the dominating part of the computing population in the global network, which is estimated to already exceed 10 billion [6]. However, IoT devices have many specifics, most notably limited computing resources and constrained energy availability-and IOTA is an alternative architecture that is supposed to suit IoT [7]. It is still in its early stages of development, which also holds true to some extent for TBC [8].…”

The immense success of Bitcoin has also highlighted the hidden potential of blockchains and distributed ledgers in general. However, most blockchains are based on the so-called Proof-of-Work principle, which requires significant resources, making them unsuitable for the growing number of Internet of Things devices, not to mention other problems such as ensuring privacy and resistance to quantum computing. This paper, therefore, analyses current approaches in the field of ledgers with applications for the Internet of Things. Based on this, it presents a new ledger architecture for cultural heritage preservation that is energy sustainable and tailored to smartphones while pushing the deployment boundaries closer to the rest of the Internet of Things world. It is also resistant to quantum computing and provides privacy with accountability. Moreover, the developed solution considers not only the core technological structure but also its broader social (business) context, i.e., links to the tourism sector. This is performed by incorporating the relevant business model, as business models are important for the successful adoption of new technologies.

“…The success of Blockchain encourages researches in this domain. A directed acyclic graph (DAG) [73] technology DLT-based named IOTA [74] is found to tackle IoT devices' scalability and Tx fees where Txs are treated simultaneously. IOTA (or Tangle) is similar to Blockchain in terms of decentralization features, but it differs in structure and behavior.…”

Modern IT technologies shaped the shift in economic models with many advantages on cost, optimization, and time to market. This economic shift has increased the need for transparency and traceability in supply chain platforms to achieve trust among partners. Distributed ledger technology (DLT) is proposed to enable supply chains systems with trust requirements. In this paper, we investigate the existing DLT-based supply chain projects to show their technical part and limitations and extract the tools and techniques used to avoid the DLT scalability issue. We then set the requirements for a typical DLT-based supply chain in this context. The analyses are based on the scalability metrics such as computing, data storage, and transaction fees that fit the typical supply chain system. This paper highlights the effects of Blockchain techniques on scalability and their incorporation in supply chains systems. It also presents other existing solutions that can be applied to the supply chain. The investigation shows the necessity of having such tools in supply chains and developing them to achieve an efficient and scalable system. The paper calls for further scalability enhancements throughout introducing new tools and/or reutilize the current ones. Doi: 10.28991/esj-2021-SP1-04 Full Text: PDF
