Blockchain-certified origin
Prove where your products come from
Prova shows how blockchain and the Digital Product Passport make a product's provenance tamper-proof — from producer to your plate, shelf or wardrobe.
How blockchain proves origin
Every supply-chain event — harvest, transport, temperature, inspection — is written to a chain of blocks. No one can change it afterwards.
Why prove origin?
Food adulteration moves billions every year. Verifiable origin is the best defense.
Food fraud
Europe will require a digital record of origin, materials and repairability. Blockchain is the natural foundation.
