Transparent Transaction Ordering in Blockchain-based Collaborative Processes

Speaker: Hassan Atwi

Abstract: Blockchain technology offers a promising solution for overcoming trust-related challenges, such as transparency in interorganizational collaborative processes. However, since the ordering of transactions in a block can affect the outcome of a process instance, fairness and transparency concerns regarding block selection may arise. In my talk, I will introduce a consensus-agnostic approach to promote transparency in transaction ordering in blockchain-based business processes. The approach allows participants to align the execution order of their transactions with their business objectives, effectively mitigating the lack of transparency associated with the arbitrary selection and ordering of transactions during block selection.

In February 2019, the Software Institute started its SI Seminar Series. Every Thursday afternoon, a researcher of the Institute will publicly give a short talk on a software engineering argument of their choice. Examples include, but are not limited to novel interesting papers, seminal papers, personal research overview, discussion of preliminary research ideas, tutorials, and small experiments.
On our YouTube playlist you can watch some of the past seminars. On the SI website you can find more details on the next seminar, the upcoming seminars, and an archive of the past speakers.
