OpenAttestation is the framework powering the nation-wide blockchain-based digital education credentials solution, OpenCerts, in Singapore. OpenAttestation turns documents into structured verifiable claims and allows the provenance of the documents to be verified on the Ethereum blockchain. These documents put users in control of their own data by allowing them to selectively obfuscate parts of the data in the document without compromising on the integrity of the document.
This presentation will focus on key learning points from deploying such solutions on a national scale:
- Batch issuing large numbers of documents
- Selective disclosure of data
- Decentralized document templating and rendering
