BHRV Verification

BHRV is DerbyFish's cheat-proof catch verification system. Every submitted catch goes through four steps to ensure legitimacy.

The Four Steps

1. Bump Board

The angler places the fish on a standard measuring board and takes a photo. The AI system:

• Detects the measuring board in the image

• Reads the measurement markings

• Estimates fish length

2. Hero Shot

A photo of the angler holding the catch. This links the catch to a specific person and provides additional species verification data.

3. Release Video

A short video of the fish being released back into the water. This proves:

• The fish was alive and healthy

• The catch happened in real time (not a pre-recorded submission)

4. Blockchain Verify

The submission is timestamped on the Flow blockchain. This creates an immutable record that:

• The catch happened at a specific time and GPS location

• The AI species identification was confirmed

• The measurement data was verified

AI Species Identification

DerbyFish uses computer vision to identify fish species from submission photos. The system:

• Identifies the species from bump board and hero shot images

• Cross-references against the derby's allowed species list

• Flags submissions that need manual review

Why BHRV Matters

Traditional fishing derbies rely on the honor system or in-person weigh-ins. BHRV allows:

• Remote participation (no need to bring fish to a weigh station)

• Catch and release competitions

• Real-time leaderboard updates

• Verifiable, tamper-proof results
