MLBSM also addresses critical issues like latency, ensuring faster transaction speeds through clustering and parallel processing. This paper presents a new extension to the Multi-Layer Blockchain Security Model (MLBSM). The proposed model is called the Enhanced Multi-Layer Blockchain Security Model (EMLBSM). The proposed EMLBSM will solve latency issues by compressing and reducing the layers of the MLBSM through merging layer2 and layer3 in the MLBSM. This paper describes the required enhanced solution for latency and scalability problems that were found in the MLBSM.<\/jats:p>","DOI":"10.3390\/info16030241","type":"journal-article","created":{"date-parts":[[2025,3,18]],"date-time":"2025-03-18T04:34:43Z","timestamp":1742272483000},"page":"241","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":46,"title":["An Enhanced Multi-Layer Blockchain Security Model for Improved Latency and Scalability"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-1762-8742","authenticated-orcid":false,"given":"Basem Mohamed","family":"Elomda","sequence":"first","affiliation":[{"name":"Egyptian e-Learning University, 33 El Messaha St., Dokki District, Giza 12611, Egypt"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-1562-301X","authenticated-orcid":false,"given":"Taher Abouzaid Abdelaty","family":"Abdelbary","sequence":"additional","affiliation":[{"name":"Egyptian e-Learning University, 33 El Messaha St., Dokki District, Giza 12611, Egypt"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2398-6207","authenticated-orcid":false,"given":"Hesham Ahmed","family":"Hassan","sequence":"additional","affiliation":[{"name":"Egyptian e-Learning University, 33 El Messaha St., Dokki District, Giza 12611, Egypt"},{"name":"Faculty of Computers and Artificial Intelligence, Cairo 12613, Egypt"}]},{"given":"Kamal S.","family":"Hamza","sequence":"additional","affiliation":[{"name":"Egyptian e-Learning University, 33 El Messaha St., Dokki District, Giza 12611, Egypt"}]},{"given":"Qasem","family":"Kharma","sequence":"additional","affiliation":[{"name":"Al-Ahliyya Amman University, Al-Saro, Al-Salt St., Amman 19111, Jordan"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,18]]},"reference":[{"key":"ref_1","first-page":"338","article-title":"Analysis of Multi-layer Information Flow in a Four-Layer Blockchain Model","volume":"Volume 2","author":"Rebollar","year":"2023","journal-title":"Computer Science On-line Conference"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"216","DOI":"10.1504\/IJCCBS.2024.143214","article-title":"Blockchain technology: Applications, security and privacy, big data, challenges and future directions","volume":"11","author":"Mukhlif","year":"2024","journal-title":"Int.
