“…But if those issue are solved; it will pave the blockchain technology as new standards of database engine. Latest study shows that by introduce Proof of Phone into Proof of Work and Proof of Stake platform to use computational capabilities of smartphone could potentially reduce the operation cost up to 98.2% compared to conventional blockchain platform (Kim et al, 2019).…”

Usage of technology to help finance audit process is not a new instance. But since the rise of 4th industrial revolution and emergence of smart technology relatively in a short period of time, adopting technology have its challenges and drawbacks. Data integrity has been an issue for finance audit process because digital data is easy to tamper. This condition makes audit process become difficult and potential of audit fraud is high. In this study we would like to explore usage blockchain technology as future database engine for Accounting Information System (AIS) through literature review on past study regarding usage of Blockchain database engine in Auditing. Blockchain as a technology relatively unheard before cryptocurrency albeit its advanced technology in data storage to ensure data integrity. We will explore the advantages and risk in adopting blockchain as well as current state of academics and technology regarding blockchain adoption. From the findings we formulate recommendation to realize usage of blockchain technology in a more accessible manner.

“…The task of optimizing a particular target value (PoB) when selecting block leaders could be applied in other areas, such as autonomous vehicle routing. Some consensus protocols, such as PoP, PoA and CHBD, propose interesting alternatives to existing protocols but are mainly theoretical in nature [57,60,72]. There is an opportunity for future researchers to study the actual implementation of these protocols to examine their feasibility and potential for practical use.…”

Blockchain Consensus: An Overview of Alternative Protocols

Blockchain networks are based on cryptographic notions that include asymmetric-key encryption, hash functions and consensus protocols. Despite their popularity, mainstream protocols, such as Proof of Work or Proof of Stake still have drawbacks. Efforts to enhance these protocols led to the birth of alternative consensus protocols, catering to specific areas, such as medicine or transportation. These protocols remain relatively unknown despite having unique merits worth investigating. Although past reviews have been published on popular blockchain consensus protocols, they do not include most of these lesser-known protocols. Highlighting these alternative consensus protocols contributes toward the advancement of the state of the art, as they have design features that may be useful to academics, blockchain practitioners and researchers. In this paper, we bridge this gap by providing an overview of alternative consensus protocols proposed within the past 3 years. We evaluate their overall performance based on metrics such as throughput, scalability, security, energy consumption, and finality. In our review, we examine the trade-offs that these consensus protocols have made in their attempts to optimize scalability and performance. To the best of our knowledge, this is the first paper that focuses on these alternative protocols, highlighting their unique features that can be used to develop future consensus protocols.
