Dalmore Foods operates a supply chain with many independent farmers, distributors and retailers who do not fully trust each other. Management proposes a blockchain to record each transfer of produce so that payment performance and delivery-time measures can be reported. Which feature of blockchain most directly supports this reporting objective?

The key supporting feature is that blockchain records are shared among participants and cannot be changed without network agreement, creating a trusted, tamper-resistant audit trail. This lets parties who distrust one another rely on the same data for performance reporting, though data entered at source must still be accurate.

  1. ARecords are shared across participants and cannot be altered without the network's agreement, giving a trusted audit trailCorrect
  2. BA central administrator can amend entries to correct errors at any time
  3. CIt automatically forecasts future delivery times using regression
  4. DIt removes the need for any data to be entered at the source

Explanation

A blockchain is a shared, append-only ledger in which entries are validated by the network and are effectively immutable, so all parties can rely on the same record. A central administrator editing entries is contrary to its design. Forecasting is an analytics function, and data still needs to be captured at source (the 'garbage in' problem remains).
