Our transaction history in the current centralized banking system has the ability to reveal a lot of private information for each spender, both to the banking system itself, but also to those entities that surround it (e.g., governments, industry etc). Examples of leaking information constitute the amounts spent, the goods on which the amounts were spent, the spending locations and the users we exchange money with. This knowledge is powerful in the hands of those who have it, and can be used in multiple ways, not always to our benefit. Cryptocurrencies, such as the famous Bitcoin, were proposed as a means to address the limitations of centralized banking systems and to offer its users privacy with regards to their transactional data. In this work, we perform a systematic literature review on the realm of privacy for electronic currencies. We present the development of digital money from electronic cash to cryptocurrencies and focus on the techniques that are employed to enhance user-privacy. Furthermore, we present flaws of the current cryptocurrency systems, which reduce the privacy of the cryptocurrency users. Finally, we describe three research directions to enhance privacy for cryptocurrencies: transaction propagation mechanisms, succinct ZK proof systems without a trusted setup, and specialised trustless zero-knowledge proofs.

This book examines the status of women in ancient Celtic society, looking at powerful fgures such as Boadicea and her struggle with the Romans. Ellis examines the rights of women in Celtic law, their position in mythology and the view that ultimately Christianity degenerated their role.

Drawing on literary, mythological, legal, and historical sources, Peter Berresford Ellis sets out to explore the reality behind the myriad images we hold today. His Celtic Women provides a balanced and informed perspective on the position of women in Celtic society and asks how much of this ancient culture has filtered down through the ages. Ellis examines the concept of the "Mother Goddess" origin of the Celts as well as the pantheon of women in Celtic mythology - from Etain and Emer, and Macha and Medb, to Rhiannon and Gwenhwyvar (Guinevere). He also discusses a wide range of important historical personalities. Although Boudicca (Boadicea) is often cited as the most powerful historical Celtic female figure - the one who led southern Britain in insurrection against the Romans - Ellis shows that she was by no means unique
