In traditional systems, a trusted authority handles all payments (e.g., a bank or a credit card company). More recently, blockchain systems have emerged as a trust-free and increasingly popular alternative.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn a blockchain system, users jointly emulate the trusted authority by running a distributed protocol to agree on the transaction history of users (i.e., the blockchain). Making blockchain systems a secure and scalable environment poses many new and fascinating challenges that require solutions from both cryptography and distributed computing. In my talk, I will explain the different areas of my research and their importance as components that make up a blockchain system. For each of these areas, I will also list some of the open questions that I plan to work on in the near future.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EBIO:\u003C\/p\u003E\r\n\r\n\u003Cp\u003EJulian Loss obtained his MSc in computer science from ETH Zurich in 2016 and his Ph.D. from the Ruhr University of Bochum in 2019. He is currently a postdoc at the University of Maryland in the group of Jonathan Katz. His interests include classic cryptographic primitive,s such as digital signatures and multi-party computation, as well as blockchain\/consensus protocols.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EJOIN THE TALK HERE: \u003Ca href=\u0022mailto:https:\/\/bluejeans.com\/821585375\u0022\u003Ehttps:\/\/bluejeans.com\/821585375\u003C\/a\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Foundations of Blockchain Systems "}],"uid":"34541","created_gmt":"2021-02-05 00:26:16","changed_gmt":"2021-02-05 02:55:24","author":"Tess Malone","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-02-11T11:00:00-05:00","event_time_end":"2021-02-11T12:00:00-05:00","event_time_end_last":"2021-02-11T12:00:00-05:00","gmt_time_start":"2021-02-11 16:00:00","gmt_time_end":"2021-02-11 17:00:00","gmt_time_end_last":"2021-02-11 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"643910":{"id":"643910","type":"image","title":"Julian Loss","body":null,"created":"1612484847","gmt_created":"2021-02-05 00:27:27","changed":"1612484847","gmt_changed":"2021-02-05 00:27:27","alt":"Julian Loss","file":{"fid":"244477","name":"loss.jpg","image_path":"\/sites\/default\/files\/images\/loss.jpg","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/loss.jpg","mime":"image\/jpeg","size":182854,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/loss.jpg?itok=hTUelZ7l"}}},"media_ids":["643910"],"groups":[{"id":"50875","name":"School of Computer Science"},{"id":"47223","name":"College of Computing"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"177814","name":"Postdoc"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003ETess Malone, Communications Officer\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Ca href=\u0022mailto:tess.malone@cc.gatech.edu\u0022\u003Etess.malone@cc.gatech.edu\u003C\/a\u003E\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
