Regulating Fishing Supply Chains With Blockchain Protection

60 second pitch

Consumers demand high quality fish at a cheap price ➡️ encourages fishers to manipulate locations, fish illegally ➡️ destroying marine life and environments

38M tons of marine life trashed from bycatch annually (WWF, 2009)

3.9B acres of seafloor habitats destroyed annually by bottom trawling (F&F Lab, 2021)

$50B of damage in nationally protected ecosystems annually from illegal fishing (Congress 2024)

Our ocean is declining because modern fishing regulations are unverifiable

So instead of threatening fishermen with laws that we can’t even enforce

We created 🌐Nautilink⚓ To help fishers get what they want whilst reaching consumer’s demands

Here’s how it works

Fishermen allow us to incorporate blockchain technology on their fishing equipment to uniquely mint transactions on a ledger IOT Devices: -Computer Vision detecting species of fish -Load Cell for weighing fish -NFC Tap for simplicity

Our mobile app tracks every step along the supply chain -From where the fish was caught, to the ship it was on, to the port, fishery, storage units, processing plants(curing, deboning, cutting), wholesale hqs, retail stores, and finally to the consumer -Our NFC technology verifies the movement of fish

In the end, the consumer scans a qr code and learns about how their fish was caught -trace of supplychain -sustainability scores of each step -price markup for proven sustainability

Then send these markups to the fishermen for their transparency and following regulations

On top of all that, we created a web app for regulators to track all this information on a dashboard -transaction tracking -supplychain visualization -sustainability scoring algorithm -report databases -research ai assistants -authentication methods -security roles

Old Description

The Problem (inspiration)

Fishing on the high seas is fragmented, unverifiable, and dangerous to the environment

and if unregulated, fishermen commit biblical levels of greed and harm the environment

Illegal, unregulated fishing steals $20–50 billion per year from nationally protected ecosystems (Congress 2024)

Bottom trawler destroys ~3.9 billion acres of seafloor habitats every single year (F&F Lab 2021)

*an area larger than the U.S. and China combined

Bycatching discards 38 million tons of marine life every year (WWF 2009)

*bycatch -> unintended non-target catch

All because modern fishing regulations are unverifiable

And the root of all evil starts from the consumer perspective, trying to hunt for the cheapest high value deals on fish.

Competitive prices create difficult conditions for fishers to operate in and make up for by cheating the law

But consumers aren't exactly happy about the environment destroyed,

they just need a way to understand how their choices affect the fishing supply chain.

Instead of relying on a global seafood traceability system is built on some magical thing called trust

we decided to build a system to verify, visualize, and improve the fishing supply chain sustainability

The Solution

And that is why we created Nautilink is a cross-platform block chain integrated system made up of 5 parts aimed to achieve 5 things

Simplicity

Support

Traceability + Transparency

Ecocentric

Security

How it works

Hardware (fishermen, supply chain etc.)

• Arduino-based NFC reader used to transmit sensor data from a hardware-agnostic fishing apparatus to NFC-tagged crates.

• Smartphone scanning of the tag logs the crate, owner, and device DIDs, along with GPS (latitude/longitude) to the blockchain.

• Blockchain integration provides a low-cost, verifiable link between physical assets and their digital records.

• Proof of concept demo: scanning the tag triggers a stepper motor (crane) to lift a cup of goldfish, simulating catch retrieval.

• Design goals: low-cost, small-scale, IoT-enabled hardware easily integrated into existing fishing equipment and vessels.

Block Chain Technology (transparent, verifiable)

Built on Solana blockchain with every crate movement, mixing of fish, and split being permanently recorded on a public, immutable ledger that anyone can verify.

Our smart contract program enforces transparent supply chain rules (weight validation, ownership transfers, and provenance tracking via our hardware) with novel state tracking to not only track crates but also track weighted many to many relationships.

• Sub-second verification - 400ms transaction finality enables real-time supply chain transparency with instant fraud detection

• Cryptographic integrity - SHA256 hashing and Ed25519 signatures all underlying trusted party hardware to ensure every crate record is tamper-proof and verifiable by regulators, consumers, and stakeholders

• Complete provenance chain - Parent-child relationships stored on-chain create an unbreakable audit trail from catch to consumer, preventing illegal fishing and supply chain fraud while creating a market for tracable fish that can align company profits with the mission of sustainability and transparency

For tobile App (consumers, fishermen, supply chain etc.) consumers would track their transactions by using QR codes and NFC tags. This interaction was depicted through a chain of nodes and edges. For the fisherman part of the app we helped them focus on fish and how they can better track their fish, which is also the main rationale behind us pursuing this idea, in tracking the fish from their inception in the oceans to their spot in our shelves we could see how efficient/inefficient certain parts of the market were and the mobile app helped in meeting this interest in the market.
