What does "Blockchain Verified Badge" mean?

CBOX digital badges ensure the authenticity and incontestability of the statements they contain thanks to blockchain technology: a computer system consisting of communication protocols and network infrastructure that allows recording any type of information in a decentralized, transparent, secure, and immutable way, proof against any tampering or corruption. Every time a badge's page is opened, a real-time verification is performed by comparing the displayed data with the data stored on the blockchain.

How is the information verified?

At the time of issuance, all the information contained in a badge is notarized on the blockchain: this means that a unique and incontrovertible "digital fingerprint", called a hash-code, is recorded. Starting from the same set of data, the generated hash-code is always the same. Even modifying just one bit of such data results in a completely different hash-code. The cryptographic process that allows verifying that data has not been tampered with consists of generating its hash-code and comparing it with the hash-code originally saved on the blockchain. The match between the two codes is the incontestable and unequivocal proof that the information contained in the certification has not been altered after issuance.
