"Blockchain Could Help Restaurants Make Sure the Seafood You Order Is Actually What Lands on Your Plate"

I vaguely recall this story from a couple years ago. Something about cats and preventing diarrhea or something. It seemed to be one of the few uses of blockchain tech that actually made sense.
Take a look at this from Futurism and I'll see if I can find a post with felines and gastric distress.
Fish Fraud

Fraud runs rampant in the seafood industry, but blockchain (the technology supporting the growing cryptocurrency market) could help ensure the fish you order in a restaurant is the fish that finds its way onto your plate.

In 2016, Oceana, an ocean conservation advocacy group, compiled a report drawing from 200 published studies on seafood fraud. Based on their findings, a whopping 20 percent of seafood is not labeled correctly. The problem extends to all corners of the globe and at all levels of the supply chain, from the people catching the fish to those distributing and selling it.

The seafood mislabeling infractions detailed in the report ranged from the relatively minor (a restaurant advertising wild salmon but serving a cheaper farmed salmon) to the downright disturbing: sushi chefs purposely mislabeling endangered whale meat as fatty tuna in order to smuggle it into the U.S.

The consequences of mislabeling pop up in global health, the economy, and conservation efforts. According to the Oceana report, the best way to combat them is by increasing traceability. The report asserts that a more detailed and transparent record of information about the fish as it moves along the supply chain could help decrease instances of mislabeling.
Blockchain could provide this record.

Tracking Seafood
Though most commonly associated with money, blockchain’s utility isn’t limited to the world of finance. At its core, the technology is simply a secure, transparent way to record transactions. A number of companies are looking for ways to apply it to the seafood supply chain....MORE
Ah yes. 2016's "All I Asked Was 'Is the Red Snapper Good Here?'" which first linked to a post by Izabella Kaminska at FT Alphaville, also illustrated by the now Chef d'Alphaville with what can only be considered a chef d'œuvre of the kindergarten-primitivist school.

All I Asked Was "Is the Red Snapper Good Here?"

Wary, yet curious, reader might be wondering "What are they going on about now?"

You may recall that some years ago the very connected (Tiger Management founder Julian Robertson's Robertson Foundation, Geneva-based British billionaire Alan Parker's Oak Foundation, Bloomberg Philanthropies, Rockefeller Bros. et al) Oceana issued a report that huge amounts of seafood were not what they purported to be.

Specifically in New York City they found, via DNA analysis, "39 percent of the 142 seafood samples collected and DNA tested from grocery stores, restaurants and sushi venues were mislabeled."

Interestingly, Oceana's approach is a bit different from many conservancy organizations, highlighted by the greeting on their homepage:  
Restoring the ocean could feed 1 billion people a healthy seafood meal every day.
They understand the oceans are a resource whose use can be optimized.

Since the report came out (discussed here at Forbes, Dec. 2012) we've been paying attention to efforts to track fishy provenance, granted that this is more out of taste considerations than ecology, but paying attention nonetheless..

Additionally, there are other concerns.
One of the fish sometimes oftentimes, especially in sushi, mislabeled as tuna is escolar.
Be wary.
Seriously, be wary*

Here's the latest on chain-of-evidence, from FT Alphaville:

Tuna blockchains and Chilean Seabass
This is a schematic from a London-based company called Provenance which is trying to “commit tuna” to the Ethereum blockchain. It comes via a report with a handy public link:...

...There’s also some grandiose prose about the importance of transparency in supply chains and the need for every bit of the production process to be digitised and registered from the point of origin on a blockchain. It’s the usual blockchain rhetoric like this:
The application links identity, location, material attributes, certifications and audit information with a specific item or batch ID. The data is stored in an immutable, decentralized, globally-auditable format which protects identities by default, allowing for secure data verification.
But also stuff like this:
Standards allow unconnected systems to communicate using the same language, structures and identifiers. GS1, for example, manages a closed set of global standards for most supply chain concepts such as barcodes and shipping container codes. There are, however, very few standards for identifying individual instances of products or their history. We are working to develop this as a community-owned, open standard.
In short, the blockchain provides an audit layer sitting on top of an existing ERP or other data management system – like Tally-O. This allows data to be shared and mass balancing of certified product to be conducted between two separate factories. Even more, it allows that data to be joined with data collected from the first mile in a trustworthy way – providing a true end-to-end record without the need to change existing interfaces to data capture.
Which begs the question is this really about blockchain technology or the formation of global best-practice standards for supply chain management and product sourcing? Because if it’s the latter, why blockchain?

The very amiable and sincere founder of Provenance is Jessi Baker. When we spoke to her on the phone she insisted that “double-spending” in supply chains is a much bigger problem than most people appreciate.

“The problem is that along the supply chain these [certificates] are being duplicated or substituted and nobody has a global view of what’s going on,” said Baker. “Our argument is that there can’t be one person to account for all of that data. A blockchain enables the fact that it doesn’t need a central broker.”

But before we outline our concerns about that idea, if the tuna blockchain was a Rorschach test might it conjure up thoughts like this?...MORE
You'll have to follow the link to see the significance of the graphical stylings.

In the meantime, there will be a time and a plaice for blockchain, we'll see if this is it.

How to Break a Market Corner: Breeding Breakthrough Helps Sushi Baron Create Sustainable Tuna

*From the Monterey Fish Market:
Members of the Gempoylidae, or snake mackerel family, contain indigestible waxy esters in their fatty tissues similar to those found in Olestra, and these esters have powerful laxative properties that affect people to varying degrees.

Escolar and oilfish caught in the South Pacific and Gulf of Mexico are two such fish, and are quite delicious, popular menu items. Freezing and cooking won't inactivate gempylotoxins, so eating no more than 3-5 ounce servings or avoiding it is the only solution.

Symptoms of this illness are illusive, sudden, and without warning. You can be affected at any time or in the most inappropriate place, and the results can be quite embarrassing, not to mention unhygienic....
Among the six 'Key findings' in the Executive Summary of the Oceana report:
  •  94 percent of the “white tuna” was not tuna at all, but escolar, a snake mackerel that has a toxin  with purgative effects for people who eat more than  a small amount of the fish.
