Legacy Chain: A Secure NFT-Based Digital will System Integrating Biometric KYC

Abstract

This research paper proposes an effective, secure, and immutable digital will system through the use of blockchain technology, aiming to replace traditional paper-based methods that are vulnerable to fraud and theft. The system utilizes the Polygon network to ensure the immutability and transparency of the Testator’s will through the use of cryptographic hashing. The system also includes a verification process with multiple tiers, including the Lawyer and the Admin, as well as an analytical dashboard for monitoring the system in real time. The innovation in the system lies in the integrationof
the "Dead Man's Switch" principle, which will notify the stakeholders in case there is no activity from the testator for some period of time. To guarantee maximum security, is mandatory for the Beneficiary to get verified through Aadhaar-based biometric authentication, that is, Face Scan, prior to transferring the property in the form of NFTs.
