Joint Proceedings of the BIR 2021 Workshops and Doctoral Consortium co-located with 20th International Conference on Perspectives in Business Informatics Research (BIR 2021)

Answer questions related to when and what data should be shared, with whom, and how the data owner should get credit or incentive to share their data are increasingly a matter of intense debate and research. In this direction, the B4TDS (Blockchain for Trusted Data Sharing) workshop has the ambition to propose new solutions strategies, approaches, and methods to organize, store, retrieve and share data exploiting the blockchain and distributed ledger technologies (DLTs). This necessity arises since software systems are moving towards blockchain and DLTs. Indeed, thanks to smart contracts, data can be manipulated and accessed by users like in standard databases. This opportunity, combined with the blockchain and DLTs potentialities, such as the integrity and immutability of data, guarantees trusted evidence of the information stored and exchanged in the blockchain without relying on a central authority. This makes the blockchain and DLTs ideal for auditing, verification, and sharing purposes, changing significantly the way to design and implement nextgeneration distributed applications. The workshop aims to bring together researchers and practitioners to discuss theoretical/practical approaches or real-life successful case studies. The B4TDS workshop accepted 2 papers from researchers affiliated in Italy and Latvia. The authors cover different aspects of blockchain and trusted data sharing. The papers were reviewed and selected by the program committee after a rigorous reviewing process. Each paper was assigned to at least three members of the program committee. More information about the selection process can be found via http://pros.unicam.it/b4tds2021/.
