Notably, interim guidelines for the development of a smart vaccination certificate (SVCs) were given by the World Health Organization (WHO) in March 2021, as well as the concept of digital vaccination certificates (DVCs). Given that SVCs were designed for COVID-19 vaccines, the Chinese Center for Disease Control and Prevention (CCDC) is seeking a technological approach for the implementation of blockchain, the underlying technology of Bitcoin, that may be used in additional vaccines in the future, according to a report by the CCDC published on February 11. The Chinese Center said:
Blockchain has “great potential” for vaccine tracking
According to the CCDC, blockchain technology has “great potential” for use in vaccination tracking since decentralizing immunization program information systems using the technology improves the protection of vaccine safety and vaccination data as well as monitoring and controlling the whole vaccine distribution process, they said: The CCDC added: Thus, as part of his plan to promote the revival of the global economy and the ease of cross-border travel, Wang Yi State Councilor and Foreign Minister of China offered what he believed to be a possible “Chinese answer.” He hoped that the international travel health certificate and vaccination passport could be mutually validated.
How the application would work
Worth mentioning processing speed and throughput are two variables restricting the performance of blockchain since collaborative vaccination information verification needs real-time data transfer. For frequent out-block actions of on-chain data, the 5G network mobile process calculi separate a transaction into issue sets, and each node handles just one tiny fragment transaction pertinent to its requirements. Over time, little pieces are combined to form bigger fragments and, ultimately, a full transaction. The authors Zixiong Zhao and Jiaqi Ma also noted that DVCs might be used in a wide number of applications when they are combined with blockchain technology; however, cybersecurity remains an issue.
Countries “should be encouraged” to adopt blockchain
Finally, globally trustworthy consortium blockchain procedures, unified encryption methods, and smart contracts to add DVCs to blockchain for certification, as well as mutual consensus, are all things the CCDC highlights should be pushed by the World Health Organization. Ultimately, they believe that countries should be encouraged to embrace international open-source blockchain and networking technology to meet global application standards.
