Abstract Blockchain technology provides basic building blocks to support the execution of collaborative business processes involving mutually untrusted parties in a decentralized environment. Several research proposals have demonstrated the feasibility of designing blockchain-based collaborative business processes using a high-level notation, such as the Business Process Model and Notation (BPMN), and thereon automatically generating the code artifacts required to execute these processes on a blockchain platform. In this paper, we present the conceptual foundations of model-driven approaches for blockchain-based collaborative process execution and we compare two concrete approaches, namely Caterpillar and Lorikeet.

Blockchain technology is argued to have the potential to facilitate the development and improvement of cross-organizational business processes, on various aspects of the business process management discipline. In this paper, we review existing work on the use of blockchain technology to support business processes with a focus on cross-organizational settings. Based on this, we suggest to view blockchain as a software connector helping organizations to integrate the IT systems they use to support business processes. In addition, this paper suggests to use a model-driven engineering approach for the development of such connectors. By doing so, the need to develop a methodology helping to model and implement blockchain-based software connectors supporting cross-organizational business processes is highlighted. By adopting such an approach, organizations would be able to facilitate and speed up the development of blockchain-based solutions. This in turn would facilitate experimentations with this technology, which is considered as an important phase for organizations to derive value from it.

Distributed Ledger Technologies and particularly Blockchain-based Decentralized Applications entail transaction data from various use cases and usage behaviors in a decentralized manner. In this context, we propose to apply Process Mining as a means to understand and quantify how a Distributed Ledger is de facto utilized. This paper introduces a heuristic Process Mining approach for extracting high level process structures from Distributed Ledgers and Decentralized Applications, which can also represent changes over time. The universal approach is demonstrated on the basis of the complete set of all transactions that happened on the Ethereum Blockchain during its first three years. Events, cases, and activities allow to compile an evolutionary time line, which shows the Blockchain evolving from its early stages to broader adoption. Furthermore, measures of activity significance, confidence, and process complexity are used to compile dependency graphs, which represent process transitions.

Immutability - the ability for a Blockchain (BC) Ledger to remain an unalterable, permanent and indelible \nhistory of transactions - is a feature that is highlighted as a key benefit of BC. This ability is very important \nwhen several companies work collaboratively to achieve common objectives. This collaboration is usually \nrepresented by using business process models. BC is considered as a suitable technology to reduce the \ncomplexity of designing these collaborative processes using Smart Contracts. This paper discusses how to \ncombine Model-based Software Development, modelling techniques, such as use cases models and activity \ndiagram models based on Unified Model Languages (UML) in order to simplify and improve the modelling, \nmanagement and execution of collaborative business processes between multiple companies in the BC \nnetwork. This paper includes the neccessity of using transformation protocols to obtain Smart Contract code. \nIn addition, it presents systematic mechanisms to evaluate and validate Smart Contract, applying early testing \ntechniques, before deploying the Smart Contract code in the BC network.

Smart contracts are self-executing contracts defining rules for negotiating, verifying the fulfillment of rules and executing the agreement using formal code. They run on top of a blockchain. Errors in smart contracts are costly and are mostly found too late after execution, which is too late for fixing. To improve the validation of executed smart contracts, this paper suggests a process mining based approach. For this, we present an approach for the extraction of meaningful event logs from a blockchain. The event log can be imported in any process mining tool and validation and verification techniques can be used allowing to diagnose (non)conformity in smart contracts by means of common quality measures and with low latency after smart contract execution.

Intelligent Cyber-physical systems can be modelled as multi-agent systems\nwith planning capability to impart adaptivity for changing contexts. In such\nmulti-agent systems, the protocol for plan execution must result in the proper\ncompletion and ordering of actions in spite of their distributed execution.\nHowever, in untrusted scenarios, there is a possibility of agents not\nrespecting the protocol either due to faults or due to malicious reasons\nthereby resulting in plan failure. In order to prevent such situations, we\npropose to implement the execution of agents through smart contracts. This\npoints to a generic architecture seamlessly integrating intelligent\nplanning-based CPS and smart-contracts.\n

Blockchain technology enables the execution of collaborative business processes involving mutually untrusted parties. Existing platforms allow such processes to be modeled using high-level notations and compiled into smart contracts that can be deployed on blockchain platforms. However, these platforms brush aside the question of who is allowed to execute which tasks in the process, either by deferring the question altogether or by adopting a static approach where all actors are bound to roles upon process instantiation. Yet, a key advantage of blockchains is their ability to support dynamic sets of actors. This paper presents a model for dynamic binding of actors to roles in collaborative processes and an associated binding policy specification language. The proposed language is endowed with a Petri net semantics, thus enabling policy consistency verification. The paper also outlines an approach to compile policy specifications into smart contracts for enforcement. An experimental evaluation shows that the cost of policy enforcement increases linearly with the number of roles and constraints.

Blockchain technology has seen significant growth, hype, and potential new developments over the past few years. In this article additional insights into how blockchain can add value to a business process relationship is detailed. Specifically an engineering contract workflow use application pilot including various high level system architectural aspects are presented. This application shows the integration of blockchain technology with existing legacy systems. Some management and technology issues are also overviewed for the reader.

The purpose of the research paper is to describe how the Blockchain technology can foster traceability of electric/electronics (E/E) information artifacts in product lifecycle management (PLM) with a focus on bridging the gap between model-bases systems engineering (MBSE) and product data management (PDM). Due to automotive development includes many parties, such as original equipment manufacturers (OEMs), suppliers, and new partners, a distribution mechanism for proclamation of changed information artifacts is necessary. The approach compares MBSE methods and identifies which information artifacts created there have to be linked with PDM artifacts. Practical implications for the exchange of data in engineering collaboration with multiple partners are assessed by a first proof of concept with a Blockchain prototype tested with a supplier. The originality of this approach stems from the application of the Blockchain technology in engineering IT, a meta data model to connect MBSE and PDM, and the facilitated inclusion of engineering collaboration partners by those means.

A new initiative from the International Swaps and Derivatives Association (ISDA) aims to establish a Common Domain Model (ISDA CDM): a new standard for data and process representation across the full range of derivatives instruments. The resulting standardisation of workflow will not only reduce the cost of traditional processing but will also facilitate new platforms using distributed ledger technology and enable processing via smart contracts. The design of the ISDA CDM is at an early stage and the draft definition contains considerable complexity and ambiguity. This paper contributes by offering insight, critical analysis and discussion relating to important topics in the design space such as data lineage, timestamps, consistency, operations, events, state and state transitions.
