Blockchain provides a immutable and decentralized database that can help all parties ensure the correct storage and handling of vaccine supplies.
After monitoring each vaccine through the blockchain, each link in the chain can track the entire process, and the health department can monitor the entire chain and intervene if necessary to ensure that it works properly.
Especially for the urgently needed COVID-19 vaccine around the world, the correct storage of evidence recorded on the blockchain is invaluable.
