“…Modelling of blockchain-based processes requires blockchain-specific modelling constructs. BlockME provides an extension to BPMN for describing transaction state changes [15]. It also implements an interface between blockchains and the workflow engine, allowing workflow tasks to track transaction status and submit new transactions.…”

Blockchain technology, originally popularized by cryptocurrencies, has been proposed as an infrastructure technology with applications in many areas of business management. Blockchains provide an immutable record of transactions, which makes them useful in situations where actors must cooperate but may not fully trust each other. In this paper, we examine the use of proof-of-work blockchains for executing inter-organizational workflows. We discuss architectural options and describe two prototype implementations of a blockchain-based workflow management system (WfMS), highlighting differences to traditional WfMS. Our main contribution is the identification of potential problems raised by proof-of-work blockchain infrastructure and recommendations to address them.

“…Seven articles focus on the modeling of business processes on the Blockchain. One publication develops an integration architecture that abstracts the functions of a public Blockchain and thus allows external applications, such as process engines, to communicate with the Blockchain [16]. Further work identifies two approaches for combining choreographies with Blockchain platforms [17].…”

Blockchain Technology emerged recently in the area of Business Process Management and is still in its infancy. This paper analyses and evaluates the current scientific literature on the subject matter and synthesizes common topics, in order to create an understanding of the status quo. In a structured literature review, more than 300 publications were identified, of which 24 were finally selected as relevant to the cross-sectional topic of Blockchain and Business Process Management (BPM). A quantitative analysis affirms the recent upcoming of the relatively young research field and narrows the identified papers into three topic clusters, namely application areas and challenges, process architecture and design, and process execution related publications.

“…Approaches range from process verification with the Bitcoin Blockchain [15] to monitoring and execution of processes based on Ethereum. Latest efforts either use standard BPMN notation [3], extend the BPMN standard [5,16,17], use other declarative workflow models [18], or rely on new modeling languages [19,20]. The most widespread concept is based on Ethereum and works with (some form of) BPMN.…”

Blockchain capabilities like Ethereum Smart Contracts offer great opportunities to manage cross-organizational business processes due to their trustless and tamperproof nature. However, communication in such processes poses a major issue since there is no direct option for one participating organization to inform other collaborators about their individual progress in their impersonation as a Smart Contract. As that knowledge is vital to execute a cross-organizational process, we design a Smart Contract architecture in which participants express their progress through Blockchain events. Furthermore, we implement a prototype that subscribes to the relevant events of one or more participants and reacts to their occurrence by triggering the subsequent step(s) of the process. Evaluation of the prototype and architecture shows that this does not only avoid unnecessary latency in process communication but also results in a fair cost distribution as each participant is only charged for the expenses of its individual actions.
