    Blockchain (BC), as an emerging technology, is revolutionizing Business Process Management (BPM) in multiple ways. The main adoption is to serve as a trusted infrastructure to guarantee the trust of collaborations among multiple partners in trustless environments. Especially, BC enables trust of information by using Distributed Ledger Technology (DLT). With the power of smart contracts, BC enforces the obligations of counterparties that transact in a business process (BP) by programming the contracts as transactions. This paper aims to study the state-of-the-art of BC technologies by (1) exploring its applications in BPM with the focus on how BC provides the trust of BPs in their lifecycles; (2) identifying the relations of BPM as the need and BC as the solution with the assessment towards BPM characteristics; (3) discussing the up-to-date progresses of critical BC in BPM; (4) identifying the challenges and research directions for future advancement in the domain. The main conclusions of our comprehensive review are (1) the study of adopting BC in BPM has attracted a great deal of attention that has been evidenced by a rapidly growing number of relevant articles. (2) The paradigms of BPM over Internet of Things (IoT) have been shifted from persistent to transient, from static to dynamic, and from centralized to decentralized, and new enabling technologies are highly demanded to fulfill some emerging functional requirements (FRs) at the stages of design, configuration, diagnosis, and evaluation of BPs in their lifecycles. (3) BC has been intensively studied and proven as a promising solution to assure the trustiness for both of business processes and their executions in decentralized BPM. (4) Most of the reported BC applications are at their primary stages, future research efforts are needed to meet the technical challenges involved in interoperation, determination of trusted entities, confirmation of time-sensitive execution, and support of irreversibility

    Using Blockchain to Improve Collaborative Business Process Management: Systematic Literature Review

    BlockChain Technology (BCT) has appeared with strength and promises an authentic revolution on business, management, and organizational strategies related to utilization of advanced software systems. In fact, BCT promotes a decentralized architecture to process management and the collaborative work between entities when these ones are working together in a business process. This paper aims to know what proposals exist to improve any stage of business process management using BCT because this technology could provide benefits in this management. For this purpose, this paper presents a systematic literature review in area of Collaborative Business Processes (CBP) in BCT domain to identify opportunities and gaps for further research. This paper concludes there is a rapid and growing interest of public bodies, scientific community and software industries to know opportunities that BCT offers to improve CBP management in a decentralized manner. However, although the topic is in early stages, there are very promising lines of research and relevant open issues, but there also is lack of scientific rigor in validation process into the different studies.2019-2

    From legal contracts to smart contracts and back again: Towards an automated approach

    Get PDF
    Blockchain smart contracts, programs with the potential to automate transactions and beyond, have gained tremendous popularity over the past years. Central to the original of smart contracts is that every computable clause of a contract or agreement is encoded into arbitrary computer logic with the aim of coding this logic into computer programs, and let the program decide and execute what happens during the contract's life span. The term smart legal contract has been coined to describe smart contracts that aim to capture legally binding agreements between parties. This dissertation presents a method to facilitate the creation of smart legal contracts that constitute a legally binding contract and that can (partially) self-enforce their terms and conditions within that contract, regardless of the blockchain platform. Understanding how blockchain technology works is pivotal to grapple the ramifications of this choice for smart contracts. Chapter 2 presents an overview of the literature on blockchain to delineate architectural perspectives on the technology, and to define its properties. Finally, the chapter points out the current challenges for the technology and gaps in literature. In Chapter 3, a background on smart contracts will be provided using a motivational example. Chapter 4 expounds the research methodology, the research paradigm adopted for the research, and the philosophy underpinning the method called Model Driven Architecture. Following, in Chapter 5 a domain model for smart legal contracts is presented. The chapter demonstrates how the contents of a legal contract could be captured in a model using a motivational example. Chapter 6 is devoted to describing the models that can be employed to write smart contracts. The chapter presents a platform specific model for the Ethereum and Hyperledger Fabric blockchain platforms. A platform agnostic model for blockchain technology is thereafter presented that captures the commonalities between these platforms. Chapter 7 discusses how the main research question is addressed. Derived from the insights of the discussion some opportunities for future research are discussed. Finally, Chapter 8 concludes the dissertation
