In a distributed ledger network, accountability can be a challenge. Many blockchain proponents prioritize accountability to the fullest extent possible, which may not align with the priorities of a food supply chain. Most blockchain systems allow every transaction's outcome to be visible across the network, which may be advantageous for a vertically integrated provider, but those who seek to secure their data can use smart contracts to manage information accessibility within the blockchain.

Yes, they can. Auditors can access a specific level of transparency regarding transactions sent to the network by supply chain participants. Alternatively, depending on the use case, the system's rules may also grant auditing bodies control within the system itself. For instance, if an audit fails, a certifier may prevent a producer from issuing additional digital assets with certification.

Blockchain can introduce transparency into the supply chain, enabling participants to access extensive information about the cargo, its location, and the parties involved in the flow. Increased transparency can lead to greater efficiencies, such as making cargo rerouting decisions while en route and enhancing customs' ability to perform risk-based inspections.
