“…These encompass single-processor systems that leverage hardware accelerators (IPs) to boost performance and massively parallel architectures capitalizing on numerous processors operating in perfect synchronization. [28,29] Despite embedded systems finding application across multiple domains, their utilization within the blockchain domain, particularly in conjunction with FPGA technology, has remained relatively limited. Although FPGAs possess internal resources like high-speed memory and parallel computing blocks that are well-suited for computationally intensive applications, they have primarily been limited to PoW consensus mechanisms.…”

Because of its versatility across various applications, Blockchain has emerged as a technology garnering significant interest. It has effectively addressed the challenge of transitioning from a low-trust, centralized ledger maintained by a single third-party to a high-trust, decentralized structure maintained by multiple entities, often referred to as validating nodes. Consequently, numerous blockchain systems have arisen for a multitude of purposes. Nevertheless, a considerable number of these blockchain systems are plagued by significant deficiencies concerning their performance and security. These issues have to be rectified before the realization of a widespread adoption. An essential element within any blockchain system is its foundational consensus algorithm, a crucial determinant of both its performance and security attributes. Consequently, to tackle the shortcomings observed in various blockchain systems, the hardware implementation of a series of established and innovative consensus algorithms was carried out as part of this work. This paper aims to compare and analyze the different consensus methods in blockchain, namely PoS (Proof of Stake), PoW (Proof of Work) and PoA (Proof of Authority) using VHDL (Very High-Speed Integrated Circuit Hardware Description Language). Each of these methods has unique characteristics that influence the validation of transactions and the addition of blocks to the blockchain. In this context, we aim to demonstrate the importance of optimizing consensus execution time via IPs (Intellectual Property) in VHDL. We also evaluate their impact on security, scalability and performance for IoT applications.

“…For instance, SHA-256 is commonly employed in password encryption, while BLAKE-256 and BLAKE2s are utilized for cryptographic key generation in biomedical image encryption and message authentication, respectively, in IoT and heterogeneous systems [24], [26]. Furthermore, diverse hash functions such as double SHA-256, Blake-256, and Scrypt are employed in different mining processes of different blockchain networks, such as Bitcoin, Decred, and Litecoin, respectively [5], [6], [11]. Practically, a versatile and reconfigurable cryptographic chip that can support multiple hash functions and accommodate arbitrary message lengths proves more cost-effective and time-efficient compared to the fabrication of multiple single-function dedicated cryptographic chips.…”

Blockchain-based Internet of Things (IoT) applications require flexible, fast, and low-power hashing hardware to ensure IoT data integrity and maintain blockchain network confidentiality. However, existing hashing hardware poses challenges in achieving high performance and low power and limits flexibility to compute multiple hash functions with different message lengths. This paper introduces the flexible and energyefficient crypto-processor (FECP) to achieve high flexibility, high speed, and low power with high hardware efficiency for blockchain-based IoT applications. To achieve these goals, three new techniques are proposed, namely the crypto arithmetic logic unit (Crypto-ALU), dual buffering extension (DBE), and local data memory (LDM) scheduler. The experiments on ASIC show that the FECP can perform various hash functions with a power consumption of 0.239-0.676 W, a throughput of 10.2-3.35 Gbps, energy efficiency of 4.44-14.01 Gbps/W, and support up to 8916-bit message input. Compared to state-of-art works, the proposed FECP is 1.65-4.49 times, 1.73-21.19 times, and 1.48-17.58 times better in throughput, energy efficiency, and energy-delay product (EDP), respectively.
