Project by WWF (NGO) and Treum (ex Viant.io, Startup)

In this project WWF and Treum are using blockchain to bring more transparency in the tuna fishing market, which is plagued with the problems of illegal fishing.

Questions & Answers

— What is blockchain?

— What is blockchain?

Blockchain is an IT technology which can be best compared to a database. You can write informations into the blockchain, much like you write information in a database or your Excel spreadsheet.

Other than your regular database a blockchain is stored (a) on multiple computers which are owned by independent parties, (b) the information inside the blockchain can only be added, never deleted (note: this is also true for write-only databases) and (c) the conflicts in different states of the blockchain are solved by computers (with the so-called consensus algorithms) and not by human intermediaries.

✅ Aha!

— Why is blockchain used here?

— Why is blockchain used here?

Blockhain enables a tamper-proof record of informations about the fished tuna across multiple parties (fishers, storage provider, wholesale markets, consumer markets, consumers). Blockchain doesn’t solve the problem with the initial accreditation, that tuna was caught legally (shit in, shit out problem), to solve this you would need an examiner on every fishing boat or trusted computer-generated data (e.g. tamper proof geotagging data) which would guarantee, that the fish was caught in a legal way.

Given, that these problems are solved in a tangible way, blockchain could provide a log with informations for all parties along the supply chain. Contrary to the regular data bases this log with informations wouldn’t be centrally controlled by one of the parties involved and would guarantee for every participant, that the information inside the log can’t be changed or deleted.

✅ Ok, got it.

— What are the next steps of this project?

— What are the next steps of this project?

Releasing transparency, traceability, tradability platforms that are more use case specific.

✅ Okay, nice.

One of the biggest challenges to full traceability is in the time it takes to process map with multiple participants. Additionally, large incumbents are just learning how to bring transparency to their consumers as well as manage a one on one digital relationship with them.

A first step to using blockchain technology would need to be the utilization of a digital traceability platform that can capture the KDEs necessary for traceability. Second, the authenticity of data is important: Any information system is only as good as the quality of its data. Cooperation of downstream supply chain actors is an important constraint on adopting blockchain traceability.
