What technology option is best for stakeholders in a supply chain needing verifiability and immutability of data?

Blockchain is the optimal technology for stakeholders in a supply chain that require verifiability and immutability of data. This is primarily because blockchain is designed to create a decentralized and distributed ledger that records transactions across multiple computers. Once data is entered into the blockchain, it is secured through cryptographic hashing, making it extremely difficult to alter or delete. This immutability ensures that all transactions are permanently recorded and can be verified by all participants in the network, fostering trust among supply chain stakeholders.

The transparency offered by blockchain means that every participant in the supply chain has access to the same information, which can significantly enhance accountability. Stakeholders can verify the integrity of data regarding the provenance of goods, inventory levels, and transaction histories, reducing the risks of fraud or errors.

In contrast, traditional databases and SQL databases typically provide centralized control, which can lead to challenges in data integrity as they are more vulnerable to tampering. Hybrid cloud solutions may combine various storage options but do not inherently provide the immutable record-keeping that blockchain does. Hence, for the specific requirements of verifiability and immutability in supply chain data management, blockchain stands out as the most suitable choice.
