BlockVault is a web-based system for registering and checking the integrity of digital documents. When a file is uploaded, the system computes its SHA-256 fingerprint and records that fingerprint through a Solidity smart contract, while the file itself and all related application data remain off-chain. The platform is built from a React and TypeScript frontend, an Express and TypeScript backend, a MongoDB database, and an Ethereum-compatible blockchain. Users can register documents, verify either a file or a hash, organize their records, request access to files owned by others, and review verification history. A central design decision is that proving a document is authentic is kept separate from being allowed to download it. This paper presents the design, modules, implementation, security controls, and test coverage described in the project documentation. The documentation reports 51 backend tests and 9 smart-contract tests; since execution logs were not available, pass status is not independently confirmed. No performance benchmarks exist, so the discussion stays within the documented functions of the system.
KEYWORDS
BlockVault pairs off-chain storage of documents and application records with on-chain registration of SHA- 256 fingerprints. Its documented modules bring registration, verification, document management, controlled access, notifications, and administration together in one web application. An important feature of the workflow is that confirming a document’s integrity and granting permission to access the original are handled separately. The blackbook records the security controls and the test coverage, while the supplied archive does not establish that the tests passed or how the system performs. The future work identified by the project includes decentralized storage, stronger key management, institutional workflows, advanced analytics, multi-chain support, and automated CI/CD.
