abstract = {Process models, e.g. BPMN models may represent how companies in an ecosystem interact with each other. However, the business model of the same ecosystem, e.g. expressed by an e3value model, is often left implicit. This hinders the proper analysis of the ecosystem at the business level, and more specifically financial assessment, for which process models are less appropriate. Therefore, the question is if we can somehow derive eeevalueSpace models from BPMN models. This would not only allow for proper business model analysis but would also facilitate business model mining, similar to the success of process mining. However, although an eeevalueSpace model and BPMN model represent the same ecosystem, their perspectives differ significantly. Therefore an automated derivation of an eeevalueSpace model from a BPMN seems not to be feasible, but we can assist the eeevalueSpace model designer with practical guidelines. We illustrate our guidelines by means of a case study about financial securities trading.},

abstract = {Blockchain systems are a new way to reduce or even eliminate the role of the middlemen in an eco-system.

In this paper, we focus on permissionless blockchains, which are systems that allow participation without upfront approval on other parties, as opposed to permissioned blockchains. Permissionless blockchain systems support direct business transactions between peers, so without any intermediate and centralized entity very well. However, the organization of the governance of such systems is less obvious. We argue that, in order to arrive at a really decentralized eco-system where power is fairly distributed, the governance should be decentralized; in other words, it should not be in the hand of one controlling entity. In this paper, we analyse, in a model-based way, for three well-known blockchain systems (Bitcoin, Ethereum, Tezos) the governance processes. Based on this analysis, we draft an improved governance process for permissionless blockchains.},
