  • Blockchain is a secure and transparent information storage and transmission technology. The data and all manipulations are irreversibly stored there in a register that can be accessed by everyone.
  • The security of the blockchain is based on cryptographic algorithms. The register is stored and checked by a large number of computers running these algorithms, called "nodes" guaranteeing its integrity.
  • The certificate was issued by the Institution itself, from its own blockchain address. Only Institutions whose legal existence has been verified by a "validator" can use BCdiploma technology to issue digital credentials. The formal proof of this verification is itself written on the blockchain. The list of authorized institutions is available here.
  • All the data you see has been entered on the blockchain. It guarantees, by its very nature, that the data it contains cannot be modified.
  • The Issuing Institution has declared the website authorized to display its certificate data on the blockchain. This information is publicly accessible from an open source blockchain browser. You can always access it from https://certificate.bcdiploma.com.
