Case 1
- 1. CASE 1 Blockchains For Agrifood A Proof of Concept Pilot 6 months in Marieke de Ruyter de Wildt and Bob Klaase 4 July 2017 Amsterdam
- 8. Pilot use-case: Manage provenance trail, ownership and custody of grapes Gain: Transparency of provenance trail Issue and manage certificates Gain: Real-time insight in product certificates’ validity and provenance 8
- 10. Use-case Accreditation body (Accredit inc.) Organic grapes Created by: Accredit inc.
- 11. Use-case Accreditation body (Accredit inc.) Certification body (Certify Union) Organic grapes Created by: Accredit inc. Issued to: Certify Union
- 14. Use-case Farmer John Organic grapes Created by: Accredit inc. Issued to: Certify Union Grape batch: #123 Signed by: Farmer John

Editor's Notes
- There are challenges of trust and transparency in: Transactions (quality of traded produce, efficiency and fairness of the transactions) Identities (who are the parties involved in the provenance trail, what is the origin of the product) Validation and verification (Can we trust the food safety, adherance to environmental- and social standards)
- LOOK FOR MORE EFFICIENCY MORE TRUST BLOCKCHAIN IS A VERY USEFULL CARRIER OF VERIFIED INFORMATION OVER CERTIFICATES NO NEED TO CALL AND VERIFY DIFFERENT SOURCES REAL-TIME ACCESS TO VERIFIED INFORMATION
- In the pilot use-case we developed an application that enables: Management of provenance trail on the blockchain Issue and manage certificates on the blockchain
- Accreditation body creates an accreditation
- Accreditation body issues an accreditation to a certification body (after receiving a positive audit report on the CB)
- The CB can grant signing authority of the certificate to a farmer
- Farmer creates batch of grapes
- Farmer certifies batch of grapes
- This certification will be registered on the blockchain
- Farmer John wants to trade the grapes to Trader Joe
- Trader Joe can verify the validity of the certificate on the blockchain
- The trade is then also registered on the blockchain
- Trader Joe wants to trade the grapes to a shop
- The shop verifies the certificate and provenance of the grapes, and the new trade is registered on the blockchain
- Auditor Andrew has discovered the use of prohibited pesticides by Farmer John, and revokes the signing authority of Farmer. Farmer John cannot certify new grapes. All issued certificates of the Farm are rendered invalid Auditors can also revoke certificates on the level of CB’s. This results in CB’s not being able to issue signing authority to farmers And all derived certificates are rendered invalid
- The revocation is also registered on the blockchain.
- It is immediately clear to everyone looking at the state of the blockchain that this certificate is revoked. This is where the true power of blockchain is visible. We don’t have to rely on complex/slow/long communication channels to inform everyone of the revoked certificates
