## 5 Conclusions and Perspectives  
In this work, we presented a novel solution for data storage and security driven by a decentralized approach and based on an innovative blockchain solution, called the MuReQua (Multichain Relative Quantum) chain [9]. While in Section 1 we gave the scenario and in Section 2 we considered the context of data storage to date, in Section 3 we introduced our Decentralized Storage and Security Engine (DeSSE). Indeed, Section 3 was divided four subsections: the first subsection describes the main functionalities of the uploading component of the solution, while the second subsection delves into additional details and insights, also presenting the functional mapping with respect to the physical architecture and examining the logical layer for uploading. The third subsection addresses the analysis of the oracle, which is the subcomponent of the uploading module that enables the infrastructure to be both crypto agile and post-quantum, thanks to two processes that are simultaneously cooperative and competitive. The fourth subsection was dedicated to the downloading component, also showing the functional mapping with respect to the physical architecture and examining the logical layer for downloading. Then, Section 4 considered the experimental results and the performance of the solution, including a comparison of performance metrics based on the six hardware layouts used for testing. The main result of the present work is a new solution for storage driven by decentralization, but with a deep inspiration coming from Quantum Mechanics and Quantum Computing, which raises the level of data protection and information security, thus contributing to the international effort to provide increasingly robust and effective solutions. As described, Section 3.3 is to highlight how a functional component of the conceptual uploading architecture serves to position the solution within a post-quantum context. This component effectively adds an additional layer of security against attacks, significantly increasing the difficulty of any potential breach. Specifically, while the previously described components required an attacker to (i) determine the number of fragments, (ii) locate each fragment, (iii) decrypt each fragment, and (iv) reconstruct the puzzle of fragments to retrieve the original file's informational content, this last key component necessitates that the attacker also complete all these tasks simultaneously. This is because, while any one of the four previous activities is being executed, the fragmentation scenario evolves dynamically. The component achieves this result by introducing dynamic fragmentation, effectively creating crypto agility. As we have seen, the authors have aimed to establish this crypto agility--an inherent characteristic of quantum and post-quantum solutions--in the most efficient way possible, considering the current scientific state of the art in Quantum

This is accomplished through the combined use of stochastic processes, which generate randomness at a low computational cost and one of the fundamental equations of Quantum Mechanics, [PERSON]'s equation. The outcome from this conceptual component is a binary daemon containing two interdependent processes that cooperate and compete with each other: (i) the first process examines one fragment at a time, reallocating it to different logical or physical positions, and (ii) the second process takes two fragments and mixes their informational content, resulting in two fragments that, after mixing, contain different information than they did before the process. As outlined in the introduction, the innovative technological solution presented here aims to address a set of requirements unmet by either localized or decentralized storage systems.
