A total of 356 research papers were analyzed using a BERT-based clustering approach, leading to the identification of five major need categories: transparency and trust, data integrity and provenance, fraud prevention in identity management, fractional ownership, and secure cross-border payments. The implementation strategies associated with these needs are linked to practical use cases across sectors such as agriculture, supply chain, fintech, real estate, and e-healthcare. The findings highlight a growing shift from Layer-1 to more scalable Layer-2 solutions, driven by lower costs and increased development flexibility. In addition, performance benchmarks and regulatory developments in the EU, US, Japan, and Singapore are examined. The study concludes by proposing an iterative adoption framework in which business needs, technological choices, and regulatory considerations continuously inform one another. 05 27 2026 05 27 2026 319 25 https://creativecommons.org/licenses/by/4.0/deed.en_US 10.37394/23202.2026.25.25 https://wseas.com/journals/systems/2026/a505118-422.pdf Sunny, F.
