Cryptocurrency P2P networks have new characteristics that propose new challenges and avoid some problems of existing P2P networks. By characterizing the most relevant cryptocurrency network, Bitcoin, we provide details on different properties of cryptocurrency networks and their similarities and differences with standard P2P network paradigms. Our study allows us to conclude that cryptocurrency networks present a new paradigm of P2P networks due to the mechanisms they use to achieve high resilience and security. With this new paradigm, interesting research lines can be further developed, both in the focused field of P2P cryptocurrency networks and also when such networks are combined with other distributed scenarios. date: 2018-03-01 date_type: published publisher: HINDAWI LTD official_url: https://doi.org/10.1155/2018/2159082 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green article_type: review verified: verified_manual elements_id: 1593701 doi: 10.1155/2018/2159082 lyricists_name: Delgado Segura, Sergi lyricists_id: SDELG94 actors_name: Cuccu, Clara actors_id: CCCUC40 actors_role: owner full_text_status: public publication: Mobile Information Systems volume: 2018 article_number: 2159082 pages: 16 issn: 1875-905X citation: Delgado-Segura, S; Perez-Sola, C; Herrera-Joancomarti, J; Navarro-Arribas, G; Borrell, J; (2018) Cryptocurrency Networks: A New P2P Paradigm.
