Paper Tournament Systems for Fishing Tournaments.
Weight Based Fishing Leagues incentivize poor treatment of fish ( such as stuffing the fish with leda to make it heavier )
In Person Tournaments transport big fish of breeding age far distances away from their habitat ( consider the size of the great lakes. A fish could be transferred miles and miles away. ) The transportation of a fish in a Livewell on a boat could be a poor condition for a breeding fish. And then when you consider the mount of time out of water for podium shots at the end of the tournament. It's Unethical.

There is not a fully verified way of proving a fisherman caught and released a fish on the body of water where the tournament is being held.

There is not a unified National Walleye league in the United States. Bassmaster is the biggest national fishing tournament sanctioning body. Walleye does not have the same unified community.

Fish Tab

users can submit fish by following the scanning steps. A fisher needs a bump shot, hero shot, and release video for a full submission.

Bump Shot

the bump shot is a picture of a fish flat on a bump board which is a ruler for fish.

Hero Shot

the hero shot is a selfie with the fish to act as the podium picture.

Release Video

the release video is a video of the fisher releasing the fish

The submission process allows you to scan your submission preocess and select the frames in which there is a bump shot, hero shot, and release video.

Verify Tab

The Verify tab is tinder for fish. Administrators in a derby can approve or deny fish if they followed the correct process.
We have implemented a Zero Knowledge Proof of Location so that the admins ( and the community ) does not see the fishers' location. The fisher does not want their "fishing spot" to be leaked when they are catching 40 incher after 40 incher.

In the future, we would like to provide this function for all community members to vote on Fish and get an option to save a fish if they like the fish nft.

Exchange & Rewards

The Exchange and Rewards tab is a way for the Sanctioning Body ( such as bassmaster ) to reward their fisherman for ethically catching and releasing fish in their tournaments. The sanctioning body rewards an in app currency for every ethically caught fish.

The sanctioning body will issue sport fishing licenses by users paying a monthly subscription ~$2/month.

Technology

• Figma for Design
• HTML, CSS for Landing Page
• React Native
• Rust Backend
• Cadence Smart COntract on Flow
• SnarkJS for ZKLocation verified with ZKVerify
• Othentic and Gaia AVS for Fish Detection and Length Estimation
• GoPro for Live Witness GPS and Catch Video
• In the future, satellite data for gps, rodtech for cool data collection of fish ( lidar bobber, tension gauge, camera, gps module )
• DJI Drone for GPS ( they are connected to 15+ when flying sometimes ) and awesome videos

We began with tons of planning.

1. We built the landing page and initial slide eck with predicted technology usage.
   We wanted Zero Knowledge Location, a good blockchain ( Flow is Perfect for us! ), and AI models implemented in our backend and usable in the react native app to detect fish on screen, and estimate length.
2. We read the docs for Flow and ZKVerify, made implementations.
3. We organized our development environment, figma, react native, rust backend, cadence smart contract for flow, zkproof stuff, gaianet.domains node for AI.
4. Implemented a UI for the app, Flow Smart Contract on TestNet, ZK Location Proof with functions for submitting to zkverify, gaianet node with a tool agent to run our backend AI function ( we could have also incorporated OpenAI's Vision API ),
5. Refined our presentation in DevFolio and Figma

flow, zkverify, eigenlayer avs (gaia)

catch a fish i dare you. FIshing is an untapped market ready for technology to become a standard part of fishing. Many people have a lack of connection with nature nowadays, ethical fish looks to not only rewards fishers for fishing ethically, but in essence, onboard them to nature. Ethical.Fish is for communities, competitions, ethical fishing, fish conservation, body of water research, fish population research, fish ai models, social fish sharing, minting your own fish, winning awesome prizes in competitions, earning for ethically fishing.

Since this is a real project named Derby.Fish, we were actually shopping for a blockchain, not wanting to need to reimplement semthing else after the hackathon or in a few months. Flow is perfect union for sportfishing. The trade off ends up being a good thing because we have more skin in the game with our sponsor implementations.

GaiaNet.Domains Node

I don't think I had enough RAM to run the node. Loved the process tho, it was great. I can't wait to work with GAIA's AVSs more. Super Easy Super Fun.

ZKVerify

We made an early ZKProof, then moved forward with the rest of the project. At the end of the Day, we don't really need to use a blockchain to implement a ZKProof and Verify system, however, we do see onchain verification of being on the lake a quite valuable resource for the future. It does not fully work, but functions are built and we can see ourselves using zkverify in the future.

Flow Smart Contract

@anthony
We deployed our Flow Smart Contract on Test Net but did not integrate with our react native project. It's a hackathon, lots to do, people to netowrk with, so little time. Network is Net worth. Thank you Flow for Flow Castle, being awesome hosts, and cool people!
