- <p>Blockchain technologies have been widely researched<br>in the last decade, mainly because of<br>the revolution they propose for different use cases.<br>Moving away from centralized solutions that abuse<br>their capabilities, blockchain looks like a great<br>solution for integrity, transparency, and decentralization.<br>However, there are still some problems to<br>be solved, lack of privacy being one of the main<br>ones. In this paper, we focus on a subset of the<br>privacy area, which is confidentiality. Although<br>users are increasingly aware of the importance<br>of confidentiality, blockchain poses a barrier to<br>the confidential treatment of data. We initiate<br>the study of cryptographic confidential computing<br>tools and focus on how these technologies can<br>endow the blockchain with better capabilities, i.e.,<br>enable rich and versatile applications while protecting<br>users’ data. We identify Zero Knowledge<br>Proofs, Fully Homomorphic Encryption, and Secure<br>Multiparty Computation as good candidates<br>to achieve this.</p>
