Evaluating Domains' Trustworthiness Based on Uncertainty-driven Methodologies in the Era of Sixth Generation

The onset of today's innovations pledges to have a beneficial influence on contemporary civilization in an era of intelligent revolutions, setting a precedent for unrivaled efficiency, creativity, and connectedness. The integration between these technologies contributes to the mutual benefit of each one, wherein this relation is a so-called ``reciprocal partnership''. For instance, the sixth generation (6G) wireless networks permit blockchain nodes to coordinate huge volumes of transaction data in real-time. On the other hand, blockchain is considered a secure valve because spectrum sharing can be automated with blockchain and smart contracts. Accordingly, analyzing and evaluating the contribution of these technologies in various domains to achieve a secure and trusted network is imperative and complicated. This process is conducted based on various conflicting criteria and high levels of uncertainty in the environment. To address these challenges, this paper merges multi-criteria decision-making (MCDM) methods, Centroidous and MOOSRA with triangular neutrosophic numbers (TNNs). The constructed model was leveraged to evaluate seven domains. The findings demonstrated how well the suggested methodology supports well-informed decision-making for the deployment of blockchain and 6G environments in real domains (D1, D2, ..., D7). Accordingly, D5 is optimal and the most trusted domain.
