BLOCKCHAIN EXPLAINED
Blockchain is a chain of linked blocks of data records , each bearing a cryptographic hash of the previous block . Once data is recorded in a block , this then becomes part of the cryptographic hash in the next block , so data cannot be altered retroactively without changing all subsequent blocks that show that data . It essentially creates a digital ledger of transactions that is duplicated and distributed across a network of participating computer systems . The technology is therefore considered secure and incorruptible .
Systems , devices and sensors that are capable of automated machine-tomachine communication can all be part of a blockchain system , and this includes food safety machines such as product inspection devices .
STARTING STEPS
How should food manufacturers approach the need to start developing a digital food supply chain ?
1 . Start auditing the nature of the food transformation data gathered in their plant plus investigate if they are collecting the necessary data for digital track and trace at batch level ;
2 . Look strategically at how this data is collected and stored . Analogue technology must be replaced with digital ; if possible , manual processes need to be automated ; data held on local servers should be migrated to a data hub on the premises or to the Cloud ;
3 . Start talking to blockchain technology providers , to get a feel for the issues at stake and what can be achieved . IBM is currently the front runner here , but there are other potential providers . System suppliers such as those in product inspection can also help ;
4 . Consider how to oversee the cultural changes that implementing this digital transformation will require within their organisation .
Many food manufacturers will find – perhaps to their surprise – that they are already in a good position to embark upon a process of transformation . The technology may seem complex , but its implementation is relatively straightforward . The change of culture , however , will need to be carefully managed . Staff will need to understand and accept that , within the blockchain , other organisations will have visibility of their company ’ s data . The transparency will be real and immutable . Leadership will be required to drive change and demonstrate commitment .
GETTING IN GOOD SHAPE
Amidst the talk of blockchains and connectivity , of digital and data , it is easy to lose sight of what this technological transformation is all about . It is about providing a system in which batches of food can be quickly tracked and traced , and in which critical actions taken by companies dealing with that food in the supply chain can be proven and trusted . Ultimately , it is about demonstrating that the necessary due diligence has been shown along the supply chain – from farm to fork – to deliver safe food to the consumer .
It is unavoidable that there will be disruption and cost to food manufacturers as the industry transitions to a digital supply chain . However , it also needs to be recognised that early entrants will gain commercially . A digital future is not just in the future , as the time to start counting and compiling , assessing , and progressing , is already here .
