With quantum computing evolving very fast as we speak, the security and integrity of blockchain-based applications will become the most crucial aspect. A proposal is raised to use blockchain technology as a platform for writing and probating ‘wills’. Blockchain technology in drafting and probating wills makes them safe from manipulations, highly secure, and transparent. It also dramatically decreases the time required without catering for the challenges created by the current system. [9] This paper presents a new method for will transfer and inheritance management by implementing quantum-resistant algorithms in the security architecture of a blockchain decentralized application (DApp). The system uses IPFS Network for data storage and quantum-safe algorithms as retrieval and sending algorithms. The system includes Quantum-Resistant Dilithium Signatures and Merkle trees as the fundamental components for safeguarding the transfers of assets and claims for inheritance. Quantum-Resistant Dilithium Signatures offer an unbreakable shield against quantum attacks that are expected to happen, which in turn safeguards the privacy and authenticity of transactions. While Merkle trees are responsible for the organization of inheritance claims in an effective and tamper-proof manner, the introduced system incorporates smart contracts to address the execution of an inheritance case, adding more security and automation to the asset distribution process. The system ensures a robust security framework by integrating quantum-resistant algorithms at the very core of the blockchain DApp for instance, retrieval and sending. This research is of great significance to blockchain technology which is the emerging technology of the future because it addresses the existing threat of quantum computing by showing the feasibility of using quantum-resistant algorithms in practical applications. As established by the findings, besides Quantum-Resistant Dilithium Signatures and Merkle trees, the systems of asset transfers and inheritance management within blockchain networks are enhanced in terms of safety and reliability. Hence, paving the road to the creation of more secure and trustworthy digital asset management systems.
