A framework for the analysis of attacks in crypto-currencies requires (a) modeling of game-theoretic aspects to analyze incentives for deviation from honest behavior; (b) concurrent interactions between participants; and (c) analysis of long-term monetary gains. Traditional game-theoretic approaches for the analysis of security protocols consider either qualitative temporal properties such as safety and termination, or the very special class of one-shot (stateless) games. However, to analyze general attacks on protocols for crypto-currencies, both stateful analysis and quantitative objectives are necessary. In this work our main contributions are as follows: (a) we show how a class of concurrent mean-payo games, namely ergodic games, can model various attacks that arise naturally in crypto-currencies; (b) we present the first practical implementation of algorithms for ergodic games that scales to model realistic problems for crypto-currencies; and (c) we present experimental results showing that our framework can handle games with thousands of states and millions of transitions."}],"quality_controlled":"1","publist_id":"7988","language":[{"iso":"eng"}],"publication_status":"published","type":"conference","file_date_updated":"2018-12-17T12:08:00Z","doi":"10.4230/LIPIcs.CONCUR.2018.11","conference":{"name":"CONCUR: Conference on Concurrency Theory","end_date":"2018-09-07","location":"Beijing, China","start_date":"2018-09-04"},"publication_identifier":{"isbn":["978-3-95977-087-3"]},"file":[{"file_size":1078309,"content_type":"application/pdf","relation":"main_file","open_access":1,"access_level":"open_access","creator":"dernst","date_created":"2018-12-17T12:08:00Z","success":1,"date_updated":"2018-12-17T12:08:00Z","file_name":"2018_CONCUR_Chatterjee.pdf","file_id":"5696"}],"publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","accept":"1","day":"01","oa_version":"Published Version","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Ergodic mean-payoff games for the analysis of attacks in crypto-currencies.","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1806.03108"}],"alternative_title":["LIPIcs"],"ddc":["000"],"department":[{"_id":"KrCh"}],"status":"public"}]
