Blockchain: Separating Fact from Fiction

Understanding the value of the technology is critical before jumping in.

Over the course of the past two years, blockchain has shown promise across nearly every industry—far beyond the confines of its cryptocurrency origins. The food industry is no exception, with key stakeholders like Walmart, Cargill, Tyson, Coca-Cola and Starbucks all announcing pilot programs this year.

 Melanie Nuce and other industry experts will participate in a blockchain panel discussion at this year’s Food Safety Supply Chain Conference | June 12–13, 2018 | Learn moreAlthough blockchain has tremendous potential to speed up food recalls and enable the information transparency that consumers demand, there are important building blocks that must be in place before planning a blockchain implementation. Test your blockchain knowledge with these statements below to see if you can separate fact from fiction. Armed with the right information, you’ll be able to better understand the value of blockchain and how it fits into an entire ecosystem of data sharing before jumping immediately to its application.

Blockchain is basically a shared database. This is true. While it’s no secret that shared databases have benefits, what makes blockchain special is that it is a distributed and immutable ledger. There is no single point of failure in a distributed ledger—it is a consensus of replicated and synchronized digital data geographically spread across multiple sites. This decentralized structure makes the data resilient to a technology or organizational failure.

Blockchain also supports “smart” supply chain contracts, meaning an automated execution of terms, conditions and business rules. Through this feature, trading partners can automatically enforce terms and conditions as previously defined, eliminating the errors and inefficiencies associated with the current manual processes based on legacy systems. A trading partner is prevented from writing a business transaction to the blockchain ledger that is outside of the rules specified in the smart contract. For retail grocery, this means far fewer item substitutions, more certainty around what is being shipped and when, and fewer discrepancies downstream.

Blockchain will do for the supply chain what email did for communication. This is also true—but Rome wasn’t built in a day. It will take time for blockchain to become a ubiquitous technology on par with email, and it is likely another decade away. However, given the amount of pilot programs underway, and the commitment from technology providers like IBM, Microsoft, and SAP to develop blockchain enterprise programs, many industry analysts believe blockchain will breakthrough to start to solve business process challenges in the next three to five years.

Purchasing blockchain software is all you need to create a traceability program. This is completely false! Industry stakeholders already leverage GS1 Standards, which enable traceability by ensuring all trading partners communicate in a uniform manner. Standards ensure systems interoperability, and provide a singular approach to creating, sharing and maintaining product information that supports, at the very least, “one up/one down” visibility of the product’s movement through the distribution channel. The internal data and processes a company uses to track products is integrated into a larger system of external data exchange that takes place between trading partners. Blockchain represents an opportunity for traceability to move faster—smart contracts and immutable ledgers expedite the flow of data between supply chain partners.

Blockchain can reduce food recalls from weeks to minutes. This is true, but only with a food traceability program already in place. Traceability has been achievable without blockchain, and many leading retailers have a long history working with farmers, distributors and processors on effective food traceability programs in order to assure consumers of food safety. Product recalls are significantly faster with standards in place to help break down any barriers caused by proprietary numbering systems and manual business processes.

Ultimately, now is the time to stay educated on blockchain and follow its development closely to uncover its many opportunities.

For more details on blockchain in the food supply chain, attend the blockchain panel discussion at this year’s Food Safety Supply Chain Management Conference, on June 13 at 8:30. I will be joined by Kathleen Wybourn, Director, Food Safety Solutions, DNV Business Assurance, and Darin Detwiler, Director: Regulatory Affairs of Food and Food Industry, Northeastern University for a realistic discussion of blockchain’s ability to boost the food supply chain.

    Very nice and educative article.
    Following the lead of the large players in the industry, we are now witnessing a lot of players from the industry eager to test this technology. Using blockchain can add a lot of value to the existing traceability set-up, and make it lucrative for smaller industry participants to make their supply chains transparent.
    We track the enterprise adoption of blockchain and have witnessed a steady increase in adoption in the last three quarters. The good thing is that unlike the banking industry, the project commercialization rate is better in the F&B industry.

    I believe this article provides balanced view of use of blockchain for food safety. As always, with every advantage there is a challenge/opportunity to improve upon (I avoid using term “disadvantage”). One that comes to my mind as far as an opportunity to improve upon for use of blockchain for food safety is – Data input Integrity. Ideally all stakeholders involved should systematically adhere to data input integrity to achieve full benefit of blockchain to ensure their product safety and consumer trust in their product(s).. And I know this is a “wishful thinking”, however I do believe that once the involved stakeholder(s) experience the cost of damage to their brand and company’s bottom line by not adhering to data input integrity; they will be eager/strongly inclined to find the “bad apple(s)” and implement steps to avoid such event in future. I look forward to thoughts from all the experts out there.
