Certification & Verification of data

The bloxberg network provides the functionality of minting a batch of data objects or singular objects a non-fungible ERC721 token. Each contract MUST include the ERC721 Metadata standard augmented with an additional field that contains a unique, cryptographic identifier of the bloxberg Research Object Certificate(s) included in the minting transaction. This process ensures that the research object certificate(s) can be resolved to an onchain transaction, thereby guaranteeing data integrity and provenance without disclosing sensitive information, if desired (see Blip research certificate). The cert-issuer API issues blockchain certificates by creating a transaction from the issuing institution to the recipient on the Ethereum blockchain that includes the hash of the certificate itself.

The certification and verification service is accessible via:

• The bloxberg Certify Application
• The bloxberg Verify Application
• API (API key must be requested via bloxberg-services (at) mpdl.mpg.de)
• Command Line (beta)
