Currently, identity and document verification use either physical documentation or centralized digital databases. A central figure is responsible for verifying these documents and this is thought to prevent document tampering. However, this does not eliminate threats of external hacking or internal bad actors and individuals to commit acts of forgery. in addition, bureaucracy and delays often occur with central entities validating documents that causes wasted time for users. Blockchain technology has brought a positive impact to document traceability and transparency across institutions and industries. This research will analyse and use non-transferable non-fungible tokens (NFTs) with smart contract functions which is a new concept for projecting digital and physical goods on a blockchain, it’s expected to represent complicated operations in an effective manner for document traceability systems, enabling a decentralized approach while preventing fraud, corruption, tampering, and counterfeiting.
