This paper presents a Blockchain-based framework for providing Blockchain services for purposes of stability in terms of consensus protocol infrastructure and governance mechanisms and accessible auxiliary services suitable for the vast majority of current business needs, including fundamental factors such as digital identity with autonomous identity, building solutions to ensure transaction privacy with zeroknowledge proofs, and other services related to digital assets. The proposed framework helps promote digital transformation for businesses, especially small and medium enterprises with limited resources and costs, to apply Blockchain technology to their business models, increasing competitive advantages and assisting the companies in focusing on business logic while still using Blockchain technology in their functions.

“…In this application, the data are manually entered, which may contain errors causing issues with the credentials created. Barros et al (2022) proposed a system architecture that allows the issuing and verifying of VCs based on SSI for proof of vaccination. The proposed design was based on Hyperledger Indy and Hyperledger Aries.…”

Health Passport: A blockchain-based PHR-integrated self-sovereign identity system

During the COVID-19 pandemic, it was necessary to validate a person’s health status along with their identity to permit travel. This was facilitated via paper-based certificates and centralized digital apps. Even after COVID-19, it is anticipated that such health status verifications will be required for travel and other purposes. As a result, there needs to be an additional credential, a “Health Passport,” that establishes whether a person satisfies the health requirements for various purposes. Digital credentials so prepared should be trustable, unforgeable, and verifiable. The Health Passport should be designed to protect the end-users’ privacy and give people control over the data they use to confirm their credentials. This article explores the requirements for a generalized Health Passport system and uses agent-oriented modeling (AOM) to design a blockchain-based self-sovereign identity (SSI) system integrated with the Personal Health Record (PHR) to address this requirement. The article demonstrates the feasibility of the solution by implementing a proof of concept on Hyperledger Indy and Aries, integrated with the PHR – MediTrans. Credential issuance and verification time were calculated, and it was observed that the time overhead was minimal. This solution allows users to verify their credentials with the verifier without revealing any significant personal information. Our solution can be integrated into any PHR solution as the SSI solution is added as a plugin to the PHR accessible via a mobile/web app.
