Abstract

Blockchain and distributed ledger technologies (DLTs) have emerged as one of the most revolutionary developments in recent years, with the goal of eliminating centralized intermediaries and installing distributed trusted services. They facilitate trustworthy trades and exchanges over the Internet, power cryptocurrencies, ensure transparency for documents, and much more. Although based on cryptographic techniques at their core, the currently deployed DLTs do not address privacy. Indeed, the very idea of a public ledger that stores a verifiable record of transactions at first appears inherently incompatible with the privacy requirements of many potential applications, which handle sensitive data such as trade secrets and personal information. New cryptographic techniques and protocols are therefore needed to protect the data, facilitate these applications, and make DLTs deliver on their promises. The purpose of the proposed workshop on Privacy-Enhancing Cryptography in Ledgers is to bring together researchers and practitioners working in cryptography, security, and distributed systems from academia and industry, who are interested in cryptographic techniques for improving the privacy of blockchains and their protocols. The main goal is to foster information exchange between attendees from the different areas, to present new developments in cryptographic schemes and protocols, as well as applications and challenges in order to stimulate both use of new cryptographic techniques to improve DLT-based systems as well as future cryptographic research targeting applications in DLT.
