CVSS: A Blockchainized Certificate Verifying Support System

By using a decentralized peer-to-peer network together with public and distributed ledger to decentralize the central authority, Blockchain has shown its great potential with the success of Bitcoin. However, the blockchain technology can go beyond financial transactions. In this paper, we propose an approach that utilizes the blockchain technology to issue immutable digital certificates and improve the current limitations of the existing certificate verifying systems such as faster, more trusted, and independent of the central authority. Our prototype has been successfully deployed for several short-term courses at the Center of Computer Engineering, HCMC University of Technology, Vietnam. This result indicates that our proposed system is an appropriate solution adopting ICT for e-government, especially in certificate and diploma management.
