Title:
ShareLock: Mixing for Cryptocurrencies from Multiparty ECDSA
Authors: Omer Shlomovits, István András Seres
Abstract:Many cryptocurrencies, such as Bitcoin and Ethereum, do not provide any financial privacy to their users. These systems cannot be used as a medium of exchange as long as they are transparent. Therefore the lack of privacy is the largest hurdle for cryptocurrency mass adoption next to scalability issues. Although many privacy-enhancing schemes had been already proposed in the literature, most of them did not get traction due to either their complexity or their adoption would rely on severe changes to the base protocol. To close this gap, in this work we propose ShareLock, a practical privacy-enhancing tool for cryptocurrencies which is deployable on today’s cryptocurrency networks.
