Provenance, Blockchain, and Smart Contracts as a Traceable Soil Mapping Solution

Abstract

Blockchain technology combined with Data provenance is one way to make soil data more trustworthy and traceable by providing tamper-proof information about the origin, transformations, and history of pieces of data. We present Hyperledger Fabric of FAIRCHAIN, a computational infrastructure that manages smart contracts that uses soil data. We aim to mitigate the open challenges of the agricultural food supply chain, specifically in the difficulty of traceability of soil data. In this work, we present the mechanism to structure a smart contract using soil data enriched with retrospective provenance metadata. The infrastructure can hold workflow implementations.
