Summary

Chefs can make sure their food is sustainably sourced and organic through blockchain technology. How to make sure of that? IBM thinks the solution lies in Blockchain. IBM is connecting all players in the global supply chain from farmers, producers, suppliers, manufactures in a secure shared platform---blockchain.?

Blockchain is a decentralized ledger where activities throughout the whole food supply chain are recorded, verified, and become immutable at each step. This technology applies to any numbers of vegetables from fresh to packaged.?

It has three advantages:

Consumers can scan the code on the package to check where the food comes from and? whether it is genuinely fresh etc.?

It can remove the distributor in the middle.?

Traceablity (one of the functions of blockchain) can help spot the problematic food instead of decimating the whole farm in case of a food-born outbreak
