It seems like everyone is getting into blockchain these days. After all, companies claim to like ‚Äútransparency,‚ÄĚ ‚Äúsecurity,‚ÄĚ and anything to do with the rollercoaster ride that is bitcoin. But consider this: tuna.

There are now several blockchain-based projects that aim to stop illegal tuna fishing, according to a post on The Conversation by Candice Visser and Quentin Hanich from the University of Wollongong in Australia. The idea is that blockchain-verification would assure consumers and others that the fish were ethically sourced. Or maybe it’s just PR, who knows.

Blockchain is the reason that cryptocurrencies can exist‚ÄĒit‚Äôs essentially a shared digital database that can be updated, but stored entries can‚Äôt be changed or deleted. As Gizmodo‚Äôs own Bryan Menegus explained to me, it‚Äôs prohibitively hard to fake information that‚Äôs tracked using blockchain. In this case, it can certify that something is legit and ethically sourced, like tuna. Visser and Hanich continue:

The [World Wildlife Fund] pilot project will use a combination of radio-frequency identification (RFID) tags, quick response (QR) code tags and scanning devices to collect information about the journey of a tuna at various points along the supply chain. While this use of technology is not new for supply-chain tracking, the exciting part is that the collected information will then be recorded using blockchain technology.

Tracking will start as soon as the tuna is caught. Once a fish is landed, it will be attached with a reusable RFID tag on the vessel. Devices fitted on the vessel, at the dock and in the processing factory will then detect the tags and automatically upload information to the blockchain.

That means that consumers would be able to see the history of their tuna, and easily check if it‚Äôs been legally fished. The WWF is not the only ones doing this. Visser and Hanich point out that a company called Provenance is using blockchain to trace tuna from Indonesian fisheries for British consumers. Provenance also tracks cotton, coffee, and other things. There are companies using blockchain in agriculture. You can Google ‚Äúblockchain [noun]‚ÄĚ and find someone working on something blockchain related.

But here’s the thing: tuna.

I mean, there are some concerns when it comes to tuna. ‚ÄúAmong the seven principal tuna species, 41 percent of the stocks were estimated as fished at biologically unsustainable levels, while 59 percent were fished within biologically sustainable levels,‚ÄĚ according to a United Nations Food and Agriculture Organization 2016 State of World Fisheries document. ‚ÄúThere is a need for effective management to restore the overfished stocks.‚ÄĚ

I reached out to the groups involved for a comment to see how legit this is, how well Provenance‚Äôs pilot went, whether this is just a PR stunt or if there‚Äôs a plan for expanding it, and what some of the downsides are‚ÄĒwe‚Äôll update the post when we hear back. Visser and Hanich point out that eventually the RFID tags might prohibit small operators from taking part in the project.

I feel like tuna getting on the blockchain means that this tech is old news. You know, like your grandparents getting a Facebook.
