Each cannabis product is assigned a unique Groovy QR-NFT, its digital twin on a centralized Hyperledger Fabric blockchain. This digital twin, leveraging ERC-725x/y smart contracts, stores a wealth of verifiable information about the product, including its origin, strain details, cultivation practices, lab test results, and ownership history. This information is securely linked to a physical QR code printed on a tamper-evident Groovy QR-NFT tag. These tags incorporate several robust analog security features: a 3D holographic image, micro-dot printing containing covert information, and a reflective laser logo only visible with a laser beam. These physical features provide immediate visual authentication cues for consumers and retailers, adding an extra layer of security that complements the digital verification process. Furthermore, the ERC-735 standard enables secure management of claims and attestations linked to the NFT, adding another layer of verifiable information.
When a consumer scans the QR code with a smartphone, the associated smart contract interacts with the Geno-IP library on the blockchain. This allows consumers to verify product authenticity while also exploring detailed information about the strain's genetic lineage. This seamless integration of the physical tag with the digital platform empowers consumers with unprecedented transparency and strengthens trust in the product and the brand. The scan also triggers the Groovy Rewards program, awarding GROOVY tokens for each authenticated product. These tokens can be redeemed for discounts, merchandise, and other rewards, incentivizing consumer engagement and brand loyalty.
This multi-layered approach, combining robust analog security features with the power of blockchain technology, NFTs, and smart contracts, creates a highly secure and transparent system for product authentication. Groovy QR-NFT tags not only protect brands from counterfeiting but also empower consumers with the information and rewards they need to make informed purchasing decisions and participate in a more engaging and trustworthy cannabis ecosystem.
