The COVID-19 Certificate Program (CCI) is trying to develop a digital certificate that conforms to the World Wide Web Consortium (W3C) verifiable certificate standard to help rehabilitated persons with rehabilitation certificates to return to normal life.
Digital certificate
The certificate allows individuals to provide evidence that their antibodies tested positive, have recovered from coronavirus, or have been vaccinated. More than 60 SSI organizations participated in the project, including Streetcred, TNO, Esatus, Georgetown University, TrustNet from Pakistan, DIDx from South Africa, Northern Block from Canada and Consulcesi from Italy.
Health care institutions issue certificates
The above digital certificate must be issued by a health care institution. In addition, the certificate will be controlled and shared by users in a peer-to-peer (P2P) manner. In March, Microsoft ’s former CEO and founder Bill Gates said at the AMA conference at Reddit last month:
We will eventually use digital certificates to show who has recently recovered or been tested, or when they have been vaccinated.
Why choose blockchain?
The CCI solution uses blockchain protocols such as Hyperledger Aries and Hyperledger Indy. With the support of verifiable credentials and SSI, it can establish a higher level of trust between the issuer, holder and verifier of the credential. The licensee has the right to choose what and with whom to share.
The certificate will be supported by a distributed ledger (DLT) architecture, and not much data will run on the blockchain. Drummond Reed, Chief Trust Officer of Evernym, said:
For a blockchain used only for encryption infrastructure, there will be very little data stored on the chain. All certificates are exchanged point-to-point off-chain. The use of blockchain is very important, but its role is limited.
