In this work we address the problem of coordinated consumption shifting for electricity prosumers. We show that individual optimization with respect to electricity prices does not always lead to minimized costs, thus necessitating a cooperative approach. A prosumer cooperative employs an internal cryptocurrency mechanism for coordinating members decisions and distributing the collectively gener...

In this paper, we examine the recent trend towards in-browser mining of cryptocurrencies; in particular, the mining of Monero through Coinhive and similar codebases. In this model, a user visiting a website will download a JavaScript code that executes client-side in her browser, mines a cryptocurrency—typically without her consent or knowledge—and pays out the seigniorage to the website. Websi...

Monero is a privacy-centric cryptocurrency that allows users to obscure their transactions by including chaff coins, called “mixins,” along with the actual coins they spend. In this paper, we empirically evaluate two weaknesses in Monero’s mixin sampling strategy. First, about 62% of transaction inputs with one or more mixins are vulnerable to “chain-reaction” analysis — that is, the real input...

Privacy and anonymity are important desiderata in the use of cryptocurrencies. Monero — a privacy centric cryptocurrency has rapidly gained popularity due to its unlinkability and untraceablity guarantees. It has a market capitalization of USD 290M. In this work, we quantify the efficacy of three attacks on Monero’s untraceability guarantee, which promises to make it hard to trace the origin of...

*Correspondence: [email protected] Monero Research Lab Abstract We identify several blockchain analysis attacks available to degrade the untraceability of the CryptoNote 2.0 protocol. We analyze possible solutions, discuss the relative merits and drawbakcs to those solutions, and recommend improvements to the Monero protocol that will hopefully provide long-term resistance of the cryptocurrency...
