A Smart Contract Based Recommender System

2019

Nowadays information available on the World Wide Web has reached unprecedented growth and it makes difficult for users to find the most relevant for them. In order to alleviate such issue, Recommender Systems (RSs) have been proposed to collect opinions and preferences about a set of items, process such preferences and build a personalized information access. While the most part of current RSs exploit centralized architecture to provide the service, in this manuscript we propose an alternative approach for building a general purpose RSs that provides to users with more transparent and decentralized rating strategy. Indeed, the proposed framework is built on top of a Distributed Ledger techn…

Using Blockchain in Digitalizing Enterprise Legacy Systems: An Experience Report

2021

Blockchain technology and distributed ledger technology (DLT) offer a secure, distributed, and tamper-proof way to store and exchange information. However, apart from standard cryptocurrency-based networks, innovations and process improvements based on the blockchain technology have mostly remained on the conceptualizing stage and have not yet reached mass adoption. There is a high demand for practical experiences from developing blockchain and DLT based systems in various domains outside FinTech. This work seeks to contribute to this gap by presenting real-world experiences from developing a proof of concept for automatizing conditional payments in social benefits and healthcare domains. W…

Regulation of security tokens as financial instruments in the EU: is there a need for amendments?

2022

In 2020 the European Commission proposed laws on crypto-assets and DLT. The EU treats security tokens as financial instruments, provided that they fall into the MiFID II definition. This Thesis aims to provide classification for crypto-asset as a financial instrument, to identify regulatory gaps in the EU legislation applicable to crypto-assets that qualify as financial instruments (security tokens), and to provide recommendations in relation to security tokens regulation in the EU. The results indicate that Amending Directive will harmonize the procedure for classification of a crypto-asset as a financial instrument across the EU, but the requirement for the expected profit to be derived f…
