With a blockchain-based passport, a medical provider issues a vaccination certificate that includes an individual private key to the user. At the same time, a public key is stored on the blockchain. If the user presents the vaccination certificate as a QR code in an application, the verification agency can scan the QR code to verify the minimum information related to vaccination. In addition to details related to vaccination, users can choose whether to disclose information that can identify individuals, such as their names, date of birth and nationality.
In this case, users can protect their privacy and only prove the vaccination record. With a vaccine distribution network powered by IBM Blockchain, manufacturers can proactively monitor adverse events and improve recall management. Distributors can gain real-time visibility and improved ability to respond to supply chain disruptions. Dispensers can improve inventory management and safety monitoring.
Citizens can trust vaccines and return confidently to society. An international market for fake medicines threatens hard-won gains in the global vaccination race.
Blockchaintechnology can provide a practical solution to the challenges of vaccine verification and can help meet the requirements outlined by Frieden. Without excessive disclosure of personal identification, databases stored on blockchain are useful for data analysis.
The hash is then verified by comparing it to the hash stored on the authorized blockchain, through a smart contract. While this sounds promising, earlier this year the medical journal The Lancet published the results of a trial that used blockchain to store immunization records in India, concluding that while the results of a pilot were positive, it would not necessarily prevent errors from being made at the level of collection of data and data entry. Although blockchain cannot answer questions about the inclusiveness and equity of vaccine verification systems, it can provide a platform for success for countries trying to implement their systems safely and with the ability to manage the flow of information in real time. Blockchain-based passports are something that my blockchain development company is already working on, although I have seen others that have also entered the market, such as VeChain, an NFT-based vaccine passport and COOV, a vaccine passport application created by Blockchain Labs.
With its distributed ledger, blockchain enables logistics providers to better track product and shipment information across disparate touchpoints, exponentially increasing transparency for themselves and their customers. With its distributed and decentralized system of record, blockchain provides unalterable record as data changes hands. Some consultants in Australia have begun to advocate for a vaccine registry that uses blockchain technology, which is essentially a decentralized digital ledger, to authenticate vaccines and vaccine certificates. And for entrepreneurs in the blockchain space who are considering offering similar solutions themselves, there are some considerations to keep in mind.
Because it is decentralized and encrypted, blockchain is relatively transparent and tamper-proof, and some shipping companies already use it to improve quality control and share data between organizations responsible for moving resources through supply chains. Get inspired by how innovators are transforming their businesses through use cases built on IBM Blockchain Platform. For several years, UNICEF has been investigating the potential of blockchain to document vaccine conditions as they move through the supply chain and to prove their authenticity. With these characteristics, blockchain technology is hailed as a promising tool for managing sensitive data.
If implemented correctly, the impact of blockchain on vaccines being developed and distributed today, for COVID-19 or otherwise, could be even greater for drugs manufactured and distributed tomorrow. .
