The advantage of edge networks is their pioneering integration of other prominent technologies such as blockchain and federated learning (FL) to produce better services on wireless networks. In this paper, we propose an intelligent system integrating blockchain technologies, 5G ENs, and FL to create an efficient and secure framework for transactions. FL enables user equipment (UE) to train the artificial intelligence model without exposing the UE\u2019s valuable data to the public, or to the model providers. Furthermore, the blockchain is an immutable data approach that can be leveraged for FL across 5G ENs and beyond. The recorded transactions cannot be altered maliciously, and they remain unchanged by design. We further propose a dynamic authentication protocol for UE to interact with a diverse base station. We apply blockchain as a reward mechanism in FL to enable computational offloading in wireless networks. Additionally, we implement and investigate blockchain technology for FL in 5G UE.<\/jats:p>","DOI":"10.1155\/2021\/5550153","type":"journal-article","created":{"date-parts":[[2021,3,28]],"date-time":"2021-03-28T16:35:09Z","timestamp":1616949309000},"page":"1-14","source":"Crossref","is-referenced-by-count":26,"title":["Blockchain-Enabled 5G Edge Networks and Beyond: An Intelligent Cross-Silo Federated Learning Approach"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7848-6579","authenticated-orcid":true,"given":"Sandi","family":"Rahmadika","sequence":"first","affiliation":[{"name":"Department of Artificial Intelligence Convergence, Pukyong National University, Busan 48513, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0104-848X","authenticated-orcid":true,"given":"Muhammad","family":"Firdaus","sequence":"additional","affiliation":[{"name":"Department of Artificial Intelligence Convergence, Pukyong National University, Busan 48513, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4636-5027","authenticated-orcid":true,"given":"Seolah","family":"Jang","sequence":"additional","affiliation":[{"name":"Department of Artificial Intelligence Convergence, Pukyong National University, Busan 48513, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0466-8254","authenticated-orcid":true,"given":"Kyung-Hyune","family":"Rhee","sequence":"additional","affiliation":[{"name":"Department of IT Convergence and Application Engineering, Pukyong National University, Busan 48513, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"11","key":"1","article-title":"Mobile edge computing\u2014a key technology towards 5G.
