Documents serve as the primary mechanism for establishing identity and authorization for individuals and organizations, yet their integrity is constantly threatened by sophisticated forgery. The conventional methods for verifying these documents are fundamentally flawed; they are frequently slow, labor-intensive, and depend on centralized intermediaries, which act as single points of failure that can be compromised or become unavailable. The core challenge is the lack of a universal and reliable source of truth, making third-party validation a cumbersome process built on fragile trust. This paper introduces a decentralized verification system that directly addresses these vulnerabilities by leveraging blockchain technology as its foundational layer. The importance of the blockchain lies in its inherent immutability and decentralization; it creates a tamper-proof and perpetually accessible public notary that does not rely on any single institution. By using a distributed ledger, our system removes the central authority and instead provides a shared, cryptographic source of truth. The platform's workflow is governed by smart contracts, which manage the permissions of authorized Issuers and streamline the process for Verifiers. In our model, the Issuer registers a cryptographic proof of a document onto the blockchain after storing the file in the InterPlanetary File System (IPFS). This process creates an immutable link between the document and its certification, allowing any Verifier to instantly confirm its authenticity and integrity without needing to contact the original issuer, thereby establishing a secure, efficient, and transparent ecosystem for digital trust.
