If you're familiar with blockchain technology, you're probably thinking, "but what does Bitcoin have to do with my dinner?" While most commonly associated with the enigmatic cryptocurrency Bitcoin, its first major application, blockchain is a much wider type of technology that be utilized in the medical industry, in elections, and in keeping tabs on our food. The basic premise behind blockchain is that it creates a secure, uneditable record of transactions, which verifies the validity and source of something. With the heightened concern about where our food comes from, blockchain could be a powerful tool in our farms, grocery stores, and restaurants. By creating a verifiable record of each step along a food's sourcing, manufacturing, and distribution, the blockchain of food could lend validation to the concept of "farm to table" and substantially reduce illegitimate or mislabeled food fraud. (Food fraud currently costs the global economy a staggering 40 billion dollars annually.) Blockchain-supported verifiability is especially profound for the seafood industry, where mislabeling and deception run rampant. In our current crisis of overexploited fisheries and precarious ocean ecosystems, it is more essential than ever that we know where our seafood is coming from.
