  Farm records hold the static, temporal, and longitudinal details of the
farms. For small-scale farming, the ability to accurately capture these records
plays a critical role in formalizing and digitizing the agriculture industry.
Reliable exchange of these record through a trusted platform could unlock
critical and valuable insights to different stakeholders across the value chain
in agriculture eco-system. Lately, there has been increasing attention on
digitization of small scale farming with the objective of providing farm-level
transparency, accountability, visibility, access to farm loans, etc. using
these farm records. However, most solutions proposed so far have the
shortcoming of providing detailed, reliable and trusted small-scale farm
digitization information in real time. To address these challenges, we present
a system, called Agribusiness Digital Wallet (ADW), which leverages blockchain
to formalize the interactions and enable seamless data flow in small-scale
farming ecosystem. Utilizing instrumentation of farm tractors, we demonstrate
the ability to utilize farm activities to create trusted electronic field
records (EFR) with automated valuable insights. Using ADW, we processed several
thousands of small-scale farm-level activity events for which we also performed
automated farm boundary detection of a number of farms in different
geographies.
