“…Blockchain technology is a distributed and decentralized digital ledger system that allows for conducting secure and transparent recording, verification, and storage of transactions across a network of computers [9]. This technology consists of a chain of blocks, where each block contains several transactions, and each block is linked to the previous one through cryptographic algorithms, ensuring the immutability and integrity of the recorded data [10]. Figure 1 shows how blockchains are linked together.…”

Technology, such as blockchain, has emerged as a promising solution for addressing the challenges of e-commerce decision-making. In this study, we explore the potential benefits of integrating blockchain technology into e-commerce and its role in supporting decision-making in e-commerce. We also examine blockchain’s benefits in terms of enhanced security, transparency, and efficiency for e-commerce platforms. Furthermore, the study discusses the challenges of implementing blockchain for e-commerce, including scalability, integration, regulatory frameworks, user experience, privacy, interoperability, and sustainability. By analyzing these challenges, the study provides valuable insights for future research and development efforts to facilitate a seamless adoption of blockchain technology in e-commerce decisions. Blockchain technology holds the potential to transform an e-commerce ecosystem by overcoming these challenges and unlocking its transformative potential.

“…Initially, the centralized IoT-Cloud architecture was used to accomplish such vast development [3]. However, this architecture has several flaws that render it inadequate for future demands [4]. Some of these issues include the single point of failure if the centralized server goes down, the low degree of trust among stakeholders in the cloud given that they have access to their data, and the centralized cloud server's dependency on outside parties for data collection and upkeep [3].…”

The Internet of Things (IoT) and blockchain are both recognized as cutting-edge, popular technologies. In contrast to IoT, which pertains to the spread of linked equipment via supplying information over the Internet, blockchain offers innovative data storage and management avenues. Even as blockchain demands real-time data application and IoT specifies mechanisms to securely store and handle data overflows, a combination of the two seems promising. Blockchain, a technology created with the cryptocurrency Bitcoin, could meet the needs of the IoT. However, combining blockchain with the IoT might present a multitude of issues due to the features of blockchain and IoT technology. Although many articles have been released on the blockchain and the IoT, the concerns with this combination are still vague and dispersed. In light of this, this study seeks to give an overview of the problems that have the biggest impact on blockchain-based IoT by reviewing the pertinent peer-reviewed articles. This article also addresses some suggestions for lessening the impact of these concerns. The study considered peer-reviewed articles published within the last five years, focusing on topics related to blockchain and IoT integration. We identified 44 articles for this review. The study's significance is that it not only expands the scholarly understanding of this complex intersection between blockchain and IoT but also provides actionable insights that can drive innovation and enhance the reliability and security of IoT ecosystems in practical settings.

“…We present the hardware implementation on an FPGA, highlighting remarkable results regarding the balance between hardware resources, throughput, and power consumption using multiple cores for the SHA-256 algorithm. This proposal is particularly suitable for practical challenges in blockchain environments for IoT devices [ 22 , 23 , 24 ], achieving a throughput of approximately

Gbps with 16 cores on a single FPGA and reducing dynamic power consumption by nearly ×1000 compared to existing works. The chosen device for validating the proposal was the Xilinx Virtex 6 xc6vlx240t-1ff1156 FPGA.…”

This work proposes an implementation of the SHA-256, the most common blockchain hash algorithm, on a field-programmable gate array (FPGA) to improve processing capacity and power saving in Internet of Things (IoT) devices to solve security and privacy issues. This implementation presents a different approach than other papers in the literature, using clustered cores executing the SHA-256 algorithm in parallel. Details about the proposed architecture and an analysis of the resources used by the FPGA are presented. The implementation achieved a throughput of approximately 1.4 Gbps for 16 cores on a single FPGA. Furthermore, it saved dynamic power, using almost 1000 times less compared to previous works in the literature, making this proposal suitable for practical problems for IoT devices in blockchain environments. The target FPGA used was the Xilinx Virtex 6 xc6vlx240t-1ff1156.
