CASE STUDY / PROOF OF CONCEPT
The PoC developed within Project360 connects hashing, cryptography, distributed storage and smart contracts in a complete flow: from file selection to later verification, including a privacy mode that records the digital fingerprint only.
FROM ASSET TO EVIDENCE
INTEGRITY
Project360 developed a path in which the browser calculates the original file’s SHA-256 fingerprint and uses it as a stable reference. The content does not need to be published on-chain to remain verifiable later.
PRIVACY
The PoC integrates two paths designed by Project360: an AES-CTR encrypted copy stored on IPFS through Lighthouse, or a privacy mode that records only the hash in the smart contract.
The key is generated client-side, making custody responsibilities visible and enabling a serious discussion of requirements, roles and procedures before an operational service is designed.
Documents, designs and content can change, be duplicated or circulate outside the system that created them. Notarisation establishes verifiable time-based evidence of a file’s existence and integrity. The PoC studies this principle without turning the blockchain into a content repository.
The smart contract records the information needed for verification, while IPFS is involved only when a distributed copy is useful. This separation avoids confusing proof with storage and supports different processes for intellectual property, project documents, traceability or inter-organisational exchange.
The file can be encrypted before leaving the device. The PoC uses AES-CTR and records both the original and encrypted hashes on-chain, together with the CID and timestamp. Key custody remains a process concern rather than an implementation detail hidden by the interface.
Verification can start from an identifier, hash, file or CID. The system compares fingerprints, retrieves the registered data and, when the encrypted content and key are available, supports decryption. A PDF certificate summarises the evidence in a form that remains readable outside the application.
Project360 connected browser-side cryptographic processing, optional encryption, IPFS storage, Polygon smart-contract calls, record search, verification and certificate generation in one prototype. The work demonstrates applied Web3 understanding: technologies, dependencies, interfaces and responsibilities that must operate within one process.
The same pattern can support intellectual-property protection, document traceability, approval steps, proof of delivery and verifiable exchange between organisations. Project360 can determine when DLT adds value, design the process, integrate existing systems and build a verifiable MVP. Production evolution then covers identity, roles, custody policies, error handling, monitoring and operational continuity.
