To this end, we propose a novel selfish mining attack that aims to maximize this objective and formally model the attack as a Markov decision process (MDP). We then present a formal analysis procedure which computes an ϵ-tight lower bound on the optimal expected relative revenue in the MDP and a strategy that achieves this ϵ-tight lower bound, where ϵ > 0 may be any specified precision. Our analysis is fully automated and provides formal guarantees on the correctness. We evaluate our selfish mining attack and observe that it achieves superior expected relative revenue compared to two considered baselines.\r\nIn concurrent work [Sarenche FC'24] does an automated analysis on selfish mining in predictable longest-chain blockchains based on efficient proof systems. Predictable means the randomness for the challenges is fixed for many blocks (as used e.g., in Ouroboros), while we consider unpredictable (Bitcoin-like) chains where the challenge is derived from the previous block."}],"type":"conference","language":[{"iso":"eng"}],"year":"2024","ddc":["000"],"file":[{"date_updated":"2024-07-29T07:18:12Z","success":1,"creator":"dernst","access_level":"open_access","file_name":"2024_ACM_Chatterjee.pdf","checksum":"6122bd97b42751ff81c452a19970f67d","content_type":"application/pdf","file_size":832034,"relation":"main_file","file_id":"17334","date_created":"2024-07-29T07:18:12Z"}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"date_published":"2024-06-17T00:00:00Z","oa_version":"Published Version","project":[{"_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020","grant_number":"863818","name":"Formal Methods for Stochastic Models: Algorithms and Applications"}],"publication":" Proceedings of the 43rd Annual ACM Symposium on Principles of Distributed Computing","date_updated":"2024-07-29T07:19:33Z","corr_author":"1","publisher":"Association for Computing Machinery","status":"public","day":"17","scopus_import":"1","has_accepted_license":"1","conference":{"location":"Nantes, France","start_date":"2024-06-17","end_date":"2024-06-21","name":"PODC: Symposium on Principles of Distributed Computing"},"ec_funded":1,"file_date_updated":"2024-07-29T07:18:12Z","author":[{"orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu","first_name":"Krishnendu"},{"first_name":"Amirali","last_name":"Ebrahimzadeh","full_name":"Ebrahimzadeh, Amirali"},{"id":"67638922-f394-11eb-9cf6-f20423e08757","full_name":"Karrabi, Mehrdad","last_name":"Karrabi","first_name":"Mehrdad"},{"id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-9139-1654","first_name":"Krzysztof Z","full_name":"Pietrzak, Krzysztof Z","last_name":"Pietrzak"},{"full_name":"Yeo, Michelle X","last_name":"Yeo","first_name":"Michelle X","id":"2D82B818-F248-11E8-B48F-1D18A9856A87","orcid":"0009-0001-3676-4809"},{"last_name":"Zikelic","full_name":"Zikelic, Dorde","first_name":"Dorde","orcid":"0000-0002-4681-1699","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87"}],"_id":"17328","publication_identifier":{"isbn":["9798400706684"]},"external_id":{"arxiv":["2405.04420"]},"quality_controlled":"1","acknowledgement":"This work was supported in part by the ERC-2020-CoG 863818 (FoRM-SMArt) grant and the MOE-T2EP20122-0014 (Data-Driven Distributed Algorithms) grant.\r\n","month":"06","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Fully automated selfish mining analysis in efficient proof systems blockchains","page":"268-278","article_processing_charge":"Yes (via OA deal)","doi":"10.1145/3662158.3662769","department":[{"_id":"KrCh"},{"_id":"KrPi"}],"publication_status":"published","oa":1,"date_created":"2024-07-28T22:01:10Z"}
