StableHacks wins Toronto Fishackathon Challenge 2018

Stablehacks is pleased to announce a team comprised of Krushit Patel, Jarman Batth and Magdalene Schifferer from Stablehacks, as well as Seneca College Students Damian Murawiecki and Simon Inoc are the winners of the Toronto 2018 Fishackathon which took place at City Hall on February 10-11. The team will now submit their idea to the global Fishackathon challenge by February 18, and compete for the top prize against the 35 city winners around the world.

The team’s project addressed how might we help fishers increase the price received for their catch by giving them access to real-time market data, as well as expanding their access to different markets and buyers. Increasing the price will improve their quality of life for small scale fishers and their communities. Real-time access to market data is important because it allows fishers to negotiate for a better price with middlemen and exporters.

To address these problems, the team developed two vectors of change:

1. The development of platform that allows fishers to view current fish market prices locally and regionally, and sell their catch on a virtual marketplace using SMS technology.

2. The creation of the Ship-to-Store certification standard using blockchain technology to be adopted by retailers so they can prove to stakeholders fishers were paid fairly for their catch.

The platform is also highly scalable, and the certification standard can be used to address other issues fishers are facing. For example, the certification could be used to address illegal slavery practices by adding fisher’s work papers to the blockchain. Recording transactions on the blockchain will also give all actors on the supply chain the ability to trace individual catches. This ability is important, for example, if there is a contaminated catch, the entire species from a certain region does not have to be removed from retailer’s shelves, thus reducing waste.


The team used Firebase and Blockchain (Hyperledger Fabric) as a backend. The Blockchain Business Network was created using the Hyperledger Composer framework with chaincode written in Javascript. The team used the Ionic Framework to develop the mobile application from the buyers perspective.

The Twilio API was used to interact with text messages over SMS and store real-time prices in Firebase allowing fishers to access market prices if no internet access is available. As soon as fisher and a buyer agree on a price and the transaction is signed by both parties, the transaction record is appended into the distributed ledger (blockchain). The data can then by queried or retrieved by any party who has access to the transaction ID. Such record is tamper-proof and is immutable on the blockchain. This data is then used to provide market prices for the fishers.
