### Some Details About the Oracle Covering Step 6 of the Uploading Section  
Quantum Computing, powered by principles such as superposition and entanglement, is a leap in computation that will have wide ramifications on blockchain technology. Recent advances, including better stability of qubits and demonstrations of quantum supremacy, illustrate the increasingly impressive capability of the field. This development presents risks to blockchain systems, especially their reliance on asymmetric cryptography, which is susceptible to quantum algorithms like Shor's. Due to these threats, it becomes necessary to adapt to post-quantum cryptography. Several blockchain platforms are considering the deployment of quantum-resistant algorithms for infrastructure protection. Quantum computing could also bring scalability and efficiency to blockchain by speeding up consensus and other computation-heavy smart contract executions. However, challenges include the need for extensive infrastructure upgrades, risks of centralization due to unequal access to quantum resources, and uncertainties about the timeline for widespread quantum adoption. It also offers some very interesting opportunities in return, however. Thus, blockchain can be integrated in a proactive manner with quantum-resistant measures to be leveraged as an advancement for quantum computing. As we will see shortly in the following, in this section, instead of referring generically to Quantum Computing, we will use two specific aspects of Quantum Mechanics to make the fragments dynamic. The first is the use of Schrodinger's equation to make the position of the fragments dynamic. The second aspect employs the principle of entanglement to allow fragments to merge and partially exchange the informational content they hold. The purpose of this section is to highlight how functional component 6 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, the previously described components already required an attacker to:  
1. Determine the number of fragments;
2. Locate each fragment;
3. Decrypt each fragment;
4. Reconstruct the puzzle of fragments to retrieve the original file's informational content. This sixth key component, on the other hand, 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 sixth component achieves this result by introducing dynamic fragmentation, effectively creating crypto agility. As we will see in the following sections, 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 Computing. 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 is a binary daemon containing two interdependent processes that cooperate and compete with each other:  
1. The first process examines one fragment at a time, reallocating it to different logical or physical positions. 2. 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. With reference to point 6, an oracle responsible for crypto agility resides on a third server. In this case, crypto agility consists of:  
(6.1) Giving temporal dynamics to each fragment;  
(6.2) Colliding two fragments, A1 and A2, thus allowing the product of the interaction, which consists of the new fragments B1 and B2, to emerge. Point 6.1 is defined as dynamic evolution of the fragments.
