Skeptic’s lens: Putting tuna on a blockchain, or rather on a database?

Bumble Bee Foods, the largest branded seafood company in North America, announced Friday that it is using blockchain to trace the journey of yellow-fin tuna "from the Indonesian ocean to the dinner table."

The press release titled “Bumble Bee Foods and SAP Create Blockchain to Track Fresh Fish from Ocean to Table” explained how, thanks to blockchain, customers will get access to the complete timestamped history of each yellow-fin tuna by scanning a QR code on the packaging.
