About Vaccify

Vaccify's objective was to create a blockchain-based digital identity solution for healthcare institutes, laboratories, and testing facilities, enabling them to directly send digitally signed credentials containing people’s COVID-19 vaccination status to their smartphones. One of the main challenges was finding a way to enable verification of vaccination status in a direct and secure manner, without compromising data privacy or security. Additionally, Vaccify sought to provide users with more autonomy over their digital identity, enabling them to prove specific facts about themselves without sharing data digitally.

The Vaccify ecosystem was meticulously developed with Nordivo's extensive expertise in blockchain, web3 engineering, and custom software development. This innovative platform enables healthcare institutes, laboratories, and testing facilities to directly send digitally signed credentials containing individuals' COVID-19 vaccination status to their smartphones. Additionally, the solution facilitates aviation authorities and commercial airlines in verifying vaccination status, ultimately promoting a seamless return to normalcy in society.

Design & Solution

Nordivo worked with Vaccify to develop a custom solution based on Self-Sovereign Identity (SSI), using Hyperledger technology, including Hyperledger Indy, Hyperledger Aries, and Hyperledger Ursa. This enabled direct and secure verification of vaccination status, without compromising data privacy or security. The solution used cryptography and the Sovrin Network to ensure that all credentials were stored only on the device itself, giving people full control over what credentials they share and with whom. Nordivo used React Native, ReactJS, NodeJS, Express, MongoDB, Heroku, and Amazon Web Services (AWS) to develop the Vaccify ecosystem.

Nordivo's implementation of the ZADA Wallet ecosystem involved the development of sophisticated web applications, scalable APIs with seamless blockchain integrations, and a cross-platform mobile application (Wallet app) for enhanced accessibility. To ensure robust performance and scalability, the cloud infrastructure was built on both AWS and Heroku, delivering a reliable and efficient platform for users worldwide.

Utilizing Hyperledger technology, including Hyperledger Indy, Hyperledger Aries, and Hyperledger Ursa, the solution ensures a seamless and secure experience for sharing personal information. Additionally, cryptography and the Sovrin Network guarantee that all credentials remain solely on the user's device, providing individuals full control over their shared credentials and recipients.
