Abstract
Traditional web applications are based on a client/server architecture in which servers act as trusted entities in charge of maintaining the correct state of the system. Unfortunately, servers can be corrupted at any time or they can be attacked acting against their will and this has relevant economic consequences for business. To address this issue, in the last decades, researchers have investigated how to design systems that do not rely anymore on a single trusted party (i.e., decentralized applications) but rely, instead, on decentralized technologies (e.g. blockchain) and new cryptographic primitives, such as zkSNARK. We will initially discuss how to manage the identity of users in decentralized settings, then we will investigate the role of content provenance in such settings. Content provenance guarantees the origin of a digital asset and all the history of its legit transformations. When users can rely on a strong reputation, content provenance can be easily assured but as soon as trust is limited, such as in decentralized scenarios, new solutions are needed. Finally, in the seminar, we will discuss new solutions to guarantee content provenance specifically for images and how to exploit such solutions to support a decentralized marketplace of confidential assets that are fairly exchanged on the blockchain.

Bio
Marco Zecchini is a researcher in blockchain technologies and applied cryptography at the University of Salerno, working under the supervision of Prof. Ivan Visconti. He received a Ph.D. in Data Science at the University of Rome, "La Sapienza," under the supervision of Prof. Andrea Vitaletti. He also served as a guest researcher for six months at the Technical University of Hamburg in the “CDL-BOT” laboratory directed by Stefan Schulte. His current scientific interests include applied cryptography, verifiable computation and zero-knowledge proofs, particularly in the context of blockchain and web applications.
